Answer:a is 52 b is 65
Step-by-step explanation:
a:Write 65% as 65100.
65100 of 80 = 65100 × 80.
Therefore, the answer is 52. If you are using a calculator, simply enter 65÷100×80 which will give you 52 as the answer.
b: it is 65 because it is the same question but in reverse which still gives you the same answer.

The linear function for the number of trimmers assembled is:
y = 7 + 4x.
--------------------------------
A linear function has the following format:

In which:
- a is the rate of change.
- b is the fixed amount.
--------------------------------
- In an earlier shift, 7 trimmers had already been produced, thus 7 is the fixed amount, that is,
. - Diane assembles 4 trimmers per hour, thus the rate of change is 4, that is,

- The <u>amount of trimmers y produced after x hours</u> is given by:

If you draw that out on a coordinate grid, you get a trapezoid with one base 6 units long, one base 4 units long and a height of 4. Using the formula for area of a trapezoid
h(b1 + b2)/2
where h is the height, 4, b1 is a base, 6, b2 is the other base, 4, we get
4(4+6)/2
which is 4(10)/2 or 40/2
which gets us the answer, 20
