700 / 10 = 70
70* 7 = 490
Answer:
yards =
feet
Step-by-step explanation:
The graph is a straight line passing through the origin with equation
y = mx ( m is the slope )
Calculate slope using gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (6, 2) ← 2 points on the line
m =
=
= 
the x- axis is feet and the y-axis is yards, hence
yards =
feet
3/(x + 4) = (x + 2)/5
Multiply both sides by 5 :
5 × 3/(x + 4) = 5 × (x + 2)/5
15/(x + 4) = x + 2
Multiply both sides by x + 4 :
(x + 4) × 15/(x + 4) = (x + 4) × (x + 2)
Provided that x + 4 ≠ 0, we can cancel the factors of x + 4 on the left side:
15 = (x + 4) (x + 2)
Expand the product on the right side:
15 = x² + 6x + 8
Move everything to one side:
0 = x² + 6x - 7
We can factorize easily in this case
0 = (x + 7) (x - 1)
Then
x + 7 = 0 or x - 1 = 0
⇒ x = -7 or x = 1
If a circle is equal to 365°, take 365° and multiply is by each percentage:
Potatoes - 365° x .088 = 32.12 = 32°
Green Beans - 365 x .119 = 43.435 = 43°
Corn - 365 x .151 = 55.115 = 55°
Carrots - 365 x .108 = 39.42 = 39°
Broccoli - 365 x .197 = 71.905 = 72°
