Answer:

275 ft³

Step-by-step explanation:

Given the ratio of radii of 2 similar figures = a : b , then

ratio of volumes = a³ : b³

Here the ratio of radii = 5 : 2 , so

ratio of volumes = 5³ : 2³ = 125 : 8

Calculate the volume (V) of A using proportion

$\frac{125}{V}$ = $\frac{8}{88}$ = $\frac{1}{11}$ ( cross- multiply )

V = 275 ft³

That is the volume of figure A = 275 ft³

Answer:

C) $281.25

Step-by-step explanation:

3/15 describes you having to pay the bill in 15 days with a 3% discount.

3% = 0.03

289.95 - (298.95 x 0.03)

289.95 - 8.6985

281.25

Algebra I

Function Notation

Step-by-step explanation:

Step 1: Define

f(x) = 3x - 2

g(x) = x² - 5

Step 2: Find g(f(2))

f(2)

Substitute in x: f(2) = 3(2) - 2
Multiply: f(2) = 6 - 2
Subtract: f(2) = 4

g(f(2))

Substitute in x: g(4) = 4² - 5
Exponents: g(4) = 16 - 5
Subtract: g(4) = 11

determine if l || m based on the information given on the diagram. If yes, state the converse that proves the lines are parallel

kirza4 [7]

Answer/Step-by-step explanation:

1. YES.

Converse: If same side interior angles are supplementary, then l || m. (Same side interior angles)

Since the sum of the two same side interior angles, 65° and 115°, equals 180°, therefore, l || m.

2. YES.

Converse: if two angles angles are a linear pair, they are supplementary, therefore l || m. (Linear pair)

Thus,

128° + 53° = 180°.

3. YES.

Converse: if two angles are corresponding angles and congruent, therefore l || m. (Corresponding angles).

Thus,

The indicated angles which are equal to 90°, are corresponding angles therefore, l || m.

4. YES

Converse: if two alternate exterior angles are congruent, then l || m. (Alternate exterior angles)

Thus, the two exterior angles are congruent, therefore l || m.

Clint and Max worked out at the gym together today. Clint works out at the gym every 4 days. Max works out at the gym every 6 da

VikaD [51]

Answer:

24 days

Step-by-step explanation:

To determine the number of days until they both work out at the gym on the same day again,

Find the lowest common multiples of 4 days and 6 days

Clint (4 days) = 8, 12, 16, 20, 24, 28, 32

Max (6 days) = 12, 18, 24, 30, 36, 42

The lowest common multiple of ,4 days and 6 days is 24 days

Therefore, the number of days until they both work out at the gym on the same day again is 24 days
