C=1
since the slope is -1/4 and the y-intercept is 2, the equation would be c= -1/4x + 2. Plug the value of 4 in for x. c= (-1/4)(4) + 2, c= -1 +2, c=1

I don’t know the answer to that one can you help me please

Answer:

16/45

Step-by-step explanation:

Step 1: When dividing fractions, use “KFC”. It means Keep the first fraction, Flip the second one, and

Change it to multiplication

-4/20 ÷ -9/16 → -4/20 ∙ 16/-9

Step 2: Reduce any fractions if necessary, it makes multiplying them easier and you will have to reduce anyway at the end. It’s easier arithmetic to reduce at this step. The first fraction reduces because both the numerator and denominator are divisible by 4.

-1/5 ∙ 16/-9

Step 3: Multiply numerators and denominators together to get one fraction

(-16)/(-45)

Step 4: Cancel out the negatives, a negative divided by a negative is a positive. Our final answer is

16/45

If a circle is cut from a square piece of plywood, how much plywood would be left over? Use 3.14 for pi. one whole side is 28 in

morpeh [17]

<em>What you need to find is the extra amount of plywood. To do that, you must find the area of the square and the area of the circle and subtract them to find the answer.</em>

Formulas:
area of a square: A = bh
area of a circle: A = $\pi r^2$

square measurements:
b = 28
h = 28

circle measurements:
$\pi$ (≈3.14)
r = 14

A = (28)(28)
A = 784
area of square = 784 in^2

A = 3.14 ( $14^{2}$ )
A = 3.14 (196)
A = 615.44 in^2

784 - 615.44 = 168.56
The amount of plywood left over is 168.56 in^2.
