Answer:
8%
Step-by-step explanation:
234.25$ : 100 = 252.99$ : x
234.25x = 252.99 x 100
234.25x = 25299
25299 divided by 234.25 is 108
so answer 8%
It 13 because you subtract 6 from 74.25 and then divide by 5.25

Answer:
a. C(x) = $16, if 0 ≤ x ≤ 10
C(x) = 2x - 4 if x > 10
b. Independent: Number of DVD rentals
Dependent: Monthly cost of rentals
c. $26
Step-by-step explanation:
a. The cost (C) of renting 'x' DVDs is given by:
If 10 ≤ x ≤ 10
C(x) = $16
If x > 10
C(x) = 16 + 2(x-10)
C(x) = 2x - 4
b. Since the cost depends on the number of DVD rentals, cost is the dependent variable and number of DVD rentals is the independent variable.
c. For x = 15:
C(15) = 2*15 - 4
C(15) = $26
It costs $26 to tent 15 DVDs in one month
Answer:
Center: (-7, -4)
radius = 4
Explanation:
- Equation: (x + 7)² + (y + 4)² = 16
Circle formula:
(h, k) denotes the center of the circle, "r is radius"
Rewrite the following equation in standard form:
- (x - (-7))² + (y - (-4))² = 4²
From this identify:
- h = -7, k = -4, radius = 4
154, since 17+16+15...+1 = 154.

let each of these dots represent a student. once the first student has finished a project with everyone, cover it with your finger. then, the next student has to do a project with all the others, but not the one behind him, because the one behind him already did a project with him. Am I making sense?
