Answer:
0.8 4
3.2 16
12.8 64
Step-by-step explanation:
Proportional means that it will have a constant rate of change. If we divide 4/0.8 in the first example, we get 5. In the second example, we need to find x/3.2=5. 16/3.2=5. In the third example, we need to find 2 numbers divided by each other that equals 5. 64/12.8=5
Answer: (a)
Step-by-step explanation:
Given
Equation is
Write the cross-multiplication of the given equation i.e.
This corresponds to the option (a).
Answer: 55%
Step-by-step explanation:
We divide the number of completed deliveries by the total number of expected deliveries and multiply by 100:
22 out of 40= 22/40 ×100
= 0.55 x 100
= 55%

Answer:
x = 75
y = 105
Step-by-step explanation:
Remark
You can find y in two different ways.
One
You can recall that y is the sum of the 2 interior angles not connected to it. Those angles are called the remote interior angles. Or
Two
You can add the three angles to 180 and solve for x. Then since x and y are supplementary, you can find y.
Solution
One
y = 60 + 45
y = 105 Answer
Two
x + 60 + 45 = 180 All triangles have 180 degrees. Solve for x.
x + 105 = 180 Subtract 105 from both sides
x = 180 - 105 Combine
x = 75 Find an equation that relates x and y
x + y = 180 x and y are supplementary they add to 180
75 + y = 180 Subtract 75 from both sides.
y = 180 - 75 Combine
y = 105
