Answer:
76
Step-by-step explanation:
22-3=19
19x4=76
645 feet.
Explanation:
We know that are 3 feet in a yard, so let's set up a proportion to solve this
x215
3 feet n
-------- = -----------
1 yard 215 yards
x 215
We are solving for n. To get from 1 to 215, we multiply by 215. So to get from 3 to the answer, we must multiply by 215 as well. 3 x 215 = 645, therefore that is the answer.
Answer:

Step-by-step explanation:
because if u look sideways it shows just one step up and it's 400 or it can be 500 to get 9:45
Answer:
- 9
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square
add/subtract (half the coefficient of the x- term)² to x² - 10x
g(x) = x² - 10x + (- 5)² - (- 5)² + 16
= x² - 10x + 25 - 25 + 16
= (x - 5)² - 9 ← in vertex form
vertex = (5, - 9), hence
minimum value = - 9
Answer:
Unit cost: $2.50 per potato
Step-by-step explanation:
Set up a proportion:
<h2><u>5 potatoes</u> = <u>x potatoes</u></h2><h2>2 dollars 1 dollar</h2><h2 />
cross multiply:
2x = 5
divide by 2 on both sides
x= 5/2 or 2.5
