The ingredients are:300g rice1 brown onion210g of Thai green curry paste400 mL of coconut milk450g Chicken100g snow peas1 green capsicumIf Amber wants to make 10 servings, how much additional coconut milk does she need to use?Explanation of answer:Step 1: We know that 400 mL of coconut milk is used to make 4 servings of the recipe, but Amber wants to make 10 servings We are being asked how much extra coconut milk she will need in addition to the 400mL required for 4 servings. So, we need to work out how much coconut milk is needed for 10 – 4 = 6 servings.Step 2: To do this we need to find out how much coconut milk is needed for 1 serving. To find this we divide 400mL by 4 = 100mL. One serving equals 100 mL of coconut milk.Step 3: If 100mL makes 1 serving, then 600mL will make the extra 6 servings Amber wants to make. 100mL x 6 = 600 mL. Amber needs an additional 600mLof coconut milk to make 10 servings of the recipe.Step 4: The correct answer is d) 600 mL Please select your answer a) 1000 mL b) 800 mL c) 700 mL d) 600 mL Question 222. A delivery van has been parked in a loading zone for 38 minutesHow many minutes of parking time has the van got left?Explanation of answer:Step 1: The sign tells us that a vehicle can use a loading zone for one hour. This is the equivalent of 60 minutes.Step 2: The delivery van has been parked for 38 minutes. This means that we need to find the remaining time the van can be permitted to park in the loading zone. This can be done by subtracting 38 from 60. 60 – 38 = 22Step 3: This means that the delivery van has only 22 minutes left to stay parked in the loading zone.Step 4: The correct answer is – d) 22 minutes a) 102 minutes Refer to Explanation of Answer b) 32 minutes Refer to Explanation of Answer c) 28 minutes Refer to Explanation of Answer d) 22 minutes Correct Answer None Question 223. Ava and her 5 friends went out for dinner.The total bill for the dinner was \$146.80.Ava was the only one to have a starter with her main meal.She paid \$16 for her starter and the rest of the bill was shared equally amongst the six of them.Which expression shows the total amount of money Ava paid for her dinner?The total amount Ava paid for her dinner is equal to:Explanation of answer:Step 1: To complete this answer you must use the order of operations acronym BIMDAS (brackets, indices, multiplication, division, addition and subtraction) step by step to find the answer. We do not need to know the value amount of the meal only the expression which would lead us to the final cost.Step 2: To figure out how much it costs Ava for her meal we must break the bill into sections. If the total bill costs \$146.80, we must subtract \$16 from it to determine the portion that is to be shared. This is the first step and is represented by (146.80 – 16).Step 3: The next step requires us to divide the shared portion between the 6 friends. This would be represented by ÷ 6 in the equation.Step 4: The next step would be adding the value of the meal back onto Ava’s amount. This would be represented by +16 in the equation.Step 5: We add all the components together to give the final equation of: (146.80 – 16) ÷ 6 + 16Step 6: The correct answer is – a) (146.80 – 16) ÷ 6 + 16. Please select your answer a) (146.80 – 16) ÷ 6 + 16 b) (146.80 + 16) ÷ 6 - 16 c) (146.80 + 16) ÷ 6 d) (146.80 – 16) ÷ 6 Question 224.Ezekiel was repairing a tap in his back garden.He used an adjustable spanner to tighten the garden tap onto the pipe fixing.Ezekiel placed his spanner in the position below:He rotated the spanner through a three-quarter turn clockwise.What was the position of the spanner after that rotation?Explanation of answer:Step 1: The best way to answer this question is to use the available pictures to visualise the position of the spanner handle in a quarter, half and three-quarter turns.Step 2: Looking at the original picture we can see that the handle is slightly tilted to the right. If we rotated the spanner a quarter turn, it would look like the picture in option b), handle slighted tilted down.Step 3: A half turn would have the spanner handle facing towards the ground and the three-quarter turn would have the handle slightly facing upwards as shown in option a). This means that option a) would be the correct position for a three-quarter turn.Step 4: The correct answer is – a) a) Correct Answer b) Refer to Explanation of Answer c) Refer to Explanation of Answer d) Refer to Explanation of Answer None Question 225.The graph below shows the fundraising effort of two Surf lifesaving Clubs in 2019.How much more money did the Mullaloo SLSC raise than Fremantle SLSC?Explanation of answer:Step 1: The question asks us what is the difference between how much money each club raised. We need to find that difference.Step 2: First look at the vertical lines separating the monetary value on the horizontal axis. This tells us that each interval represents $200.Step 3: Look at the top bar representing Fremantle SLSC. The bar sits three quarters of the way across the interval between the \$1,000 and the \$1,200 lines. If the interval represents \$200, then half the interval represents \$100. So, three quarters of the interval represents \$150. We can see that the Fremantle SLSC bar extends past the \$1,000 line. We add the \$1,000 and \$150 to tell us that the Fremantle SLSC raised \$1,150.Step 4: Look at the bottom bar representing Mullaloo SLSC. The bar sits one quarter of the way across the interval between the \$1,400 and the \$1,600 lines. One quarter of the interval represents \$50. We can see that the Mullaloo SLSC bar extends past the \$1,400 line. We add the \$1,400 and \$50 to tell us that the Fremantle SLSC raised \$1,450.Step 5: To find out the difference raised between the two club we must subtract the Fremantle amount from the Mullaloo amount. So, \$1,450 – \$1,150 = \$300. Mullaloo SLSC raised \$300 more than Fremantle SLSC.Step 6: The correct answer is – d) $300 a) $1,450 Refer to Explanation of Answer b) $1,150 Refer to Explanation of Answer c) $400 Refer to Explanation of Answer d) $300 Correct Answer None Question 226.A father and his young son were watching a West Coast Eagles and Fremantle derby at Optus Stadium.The son asked his father what the green and red zones on the screen meant.The father explained that the green zone represented a goal worth 6 points and the red zone represented a behind worth 1 point.At the end of the game the winning team kick 9 goals and 8 behinds.How many points did the winning team kick, as their final score?Explanation of answer:Step 1: From the description, we know that 1 goal equals 6 points and 1 behind equals 1 point. The team kicked 9 goals and 8 behinds.Step 2: To get our answer we must first multiply 9 goals by 6 points, which equals 54 points. Secondly, we multiply 8 behinds by 1 point, which equals 8 points. We add the 54 points and 8 points together to get 62 points.Step 3: The winning team kicked 62 points as their final score.Step 4: The correct answer is – b) 62 a) 80 Refer to Explanation of Answer b) 62 Correct Answer c) 55 Refer to Explanation of Answer d) 48 Refer to Explanation of Answer None Question 227.Chris owns a farm just South of Perth. He was on the Bureau of Meteorology website looking to gather some information on the likelihood of getting above the median rainfall on his farm.What is the chance that Chris will get above the median rainfall for his farm?Explanation of answer:Step 1: To determine if Chris will get above the median rainfall on his farm, we need to look at two specific areas on the image above. First, we need to look just South of Perth to see what coloured shading is represented in the key to the right-hand side of the image. We can see that colour as being light brown/orange.Step 2: Now looking at the key we can see that the colour light brown/orange represents a 30% to 35% chance of getting above the median rainfall on his farm.Step 3: When looking at our options for the answer 30% to 35% could not be considered for “Moderately Likely” or “Likely”, as they would represent a percentage chance above 50%. “Not at all Likely” would be represented by anything close to 0% chance. This leaves us with “Unlikely”, which would represent a 30%-35% chance of getting above the median rainfall for his farm.Step 4: The correct answer is – c) Unlikely a) Moderately likely Refer to Explanation of Answer b) Likely Refer to Explanation of Answer c) Unlikely Correct Answer d) Not at all likely Refer to Explanation of Answer None Question 228. During the Corona virus pandemic, the public transport capacity in cities around Australia were affected.Each was working at a lower capacity than in normal times.Which figure shows the greatest reduction in public transport capacity?Explanation of answer:Step 1: The quickest way to answer this question is to convert the fractions into their respective percentages, so we can compare using the same units to find the greatest reduction in capacity.Step 2: For a) Brisbane at 3/4 capacity, three quarters is converted into 75%, for d) Adelaide at 2/3 capacity, two thirds is converted into 66%. We now have all the same units to compare against.Step 3: Comparing those percentages we can see that the city with the greatest reduction of capacity is Adelaide with a capacity of 66%.Step 4: The correct answer is – d) Adelaide at 2/3 capacity a) Brisbane: 3/4 capacity Refer to Explanation of Answer b) Melbourne: 68% capacity Refer to Explanation of Answer c) Sydney: 70% capacity Refer to Explanation of Answer d) Adelaide: 2/3 capacity Correct Answer None Question 229.Mikael and Astrid had just visited Karijini National Park in the Pilbara. They were staying in Newman and were on their way back to Perth.They estimated that the distance to Perth was about 1,200 kilometres. They wanted to drive an average of 400 km a day. At the end of their first day driving they reached Meekatharra.Image from: http://ontheworldmap.com/australia/state/western-australia/road-map-of-western-australia-with-cities-and-towns.htmlWhich town did they reach at the end of their second day of driving?Explanation of answer:Step 1: In answering this question we are looking for an estimated answer, but the distances travelled have to be roughly the same for each day and they are travelling in the direction of Perth as their final destination. We should look through the answers to see which one is probable.Step 2: a) Leonora – Leonora is not in the general direction of Perth so we can discount that answer.Step 3: b) Gascoyne Junction – again is not the general direction of Perth, so we can discount that as an answer.Step 4: c) Northampton – could be considered the answer, however, it deviates away from the general direction of Perth in the last part of the drive and might be considered a bit further than the 400 km drive each day.Step 5: d) Paynes Find – Is the most correct answer as it is in the general direction of Perth and is about the 400 km away from Meekatharra.Step 6: The correct answer is – d) Paynes Find a) Leonora Refer to Explanation of Answer b) Gascoyne Junction Refer to Explanation of Answer c) Northampton Refer to Explanation of Answer d) Paynes Find Correct Answer None Question 230.Recently a young skateboarder named Gui Khury in California was the first person to be able to perform a 1080-degree trick on a halfpipe — a trick in which the skater spins three full times in the air, 1,080 degrees. Before this accomplishment, the best skateboarding trick anyone has ever done was a 900-degree trick by Tony Hawk.When Tony Hawk performed his 900-degree trick, how many turns did he go through?Explanation of answer:Step 1: The key to answering this question can be found in the question. A 1080-degree trick is three full turns/spins in the air. 1 full turn or spin is 360 degrees. If we divide 1080 by 360, we will get 3 full turns. Alternatively, if we multiply 360 degrees by 3 turns, we will get 1080 degrees.Step 2: The question asks us how many turns Tony Hawk went through for a 900-degree trick. We know that 3 turns give us 1080 degrees and 2 turns would be 2 x 360 = 720 degrees.Step 3: A 900-degree turn must be between those two values. If we halve 360 degrees, we will get 180 degrees (360 ÷ 2 = 180 degrees), which means a half turn. If we add 180 degrees (½ turn) to the 720 degrees (2 turns) we get a 900-degree turn.Step 4: This means that a 900-degree trick would be 2 ½ turns or 2.5 turnsStep 5: The correct answer is – b) 2.5 turns a) 3 turns Refer to Explanation of Answer b) 2.5 turns Correct Answer c) 2 turns Refer to Explanation of Answer d) 1.5 turns Refer to Explanation of Answer None Question 2. The table below shows the attendance for the Perth Wildcats at Perth Arena from 2013 to 2016. The West Australian Newspaper reported the attendance rounded to the nearest thousand. In 2015, what attendance did the West Australian Newspaper report? Explanation of Answer: Step 1: The question asks you to look for the attendance in the 2015 season. Step 2: Look for the year – 2015 in the table and then across to the attendance figure. Step 3: The figure is 154,600. Step 4: The question says the West Australian Newspaper rounded the attendance to the nearest thousand. Step 5: You need to round 154,600 to the nearest thousand. Step 6: Look at the number in the thousands column, it is 4. Step 7: When rounding we need to look at the number on the right hand side of the number being rounded. In this case it is 6. Step 8: Because the 6 is closer to 10 we must round up the 4 in the thousands column by 1 digit to 5. This gives us 155,000. Step 9: The correct answer is – d) 155,000. a) 161 000 Refer to Explanation of Answer b) 154 000 Refer to Explanation of Answer c) 150 000 Refer to Explanation of Answer d) 155 000 Correct Answer None Question 4.
