Answer:
35
Step-by-step explanation:
We can call the amount of questions they answered as 4x, 6x and 3x respectively. Since Chandran answered 30 questions, we know that 6x = 30 so x = 5. The total number of questions Kadir and Ping Wei answered was 4x + 3x = 7x and since we know that x = 5, the answer is 7 * 5 = 35 questions.
Part A: $1920 because if you change 20%to .2 then .2*1600= 320 and 320+1600=1920
Part B: $320 because 1600/5=320 that is after taxes, before taxes it is $384 because 1920/5=384 you divided it by 5 because it is 1/5, so you divide it by 5 and then multiply it by 1 because 1/5=y/1600 so find y which is what he out in the savings account
Step-by-step explanation:
6 men → 4 days → 3 metres
1 man → 24 days → 3 metres
1 man → 8 days → 1 metres
1 man → 56 days → 7 metres
10 men → 5.6 days → 7 metres
therefore, 5.6 days

Answer:
z=70 degrees y=117 degrees
Step-by-step explanation:
To find angle z, you have to know that when two sides are against each other, they have to equal 180 degrees so 180-110 is equal to 70. Therefore z is equal to 70 degrees. To find y, you have to know that a quadrilateral's total degrees is equal to 360 degrees. Therefore, you have to do 360-93-80-70 which is equal to 117 degrees. Therefore y is equal to 117 degrees.
