Answer:
The surface area is 162 yards
Step-by-step explanation:
A = 2(w l + h l + h w)
A = 2(7 (3) + 6 (3) + 6 (7))
7 x 3 = 21
6 x 3 = 18
6 x 7 = 42
21 + 18 +42 = 81
81 x 2 = 162

Answer:
598 books
Step-by-step explanation:
Let x be the number of books in the 3rd pile. We will have then:
1st pile: 2x + 10
2nd pile: 2x
3rd pile: x
3000 = (2x + 10) + (2x) + (x)
3000 = 5x + 10
3000 - 10 = 5x
2990 = 5x
2990/5 = x
x = 598 books in the third pile!
We can check that:
3000 = 2*598 + 10 + 2*598 + 598
3000 = 1196 + 10 + 1196 + 598
3000 = 3000 CHECK!
Answer:
x=3
Step-by-step explanation:
2^x=9-1
2^x=8
2^x=2^3
x=3
The rate of change of y with respect to x is - 7 / 4
<h3>what is rate of change:</h3>
The rate of change is the rate at which one quantity changes in relation to another.
Therefore, the rate of change of y with respect to x is an evaluation of how much y changes per unit change in x.
Therefore,
let's use (9, 8) and (5, 15)
Rate of change = 15 - 8 / 5 - 9
Rate of change = 7 / - 4
Rate of change = - 7 /4
