Solve this inequality: 3b – 7 < 32 A. b < 8.33
B. b < 39
C. b < 5
D. b < 13

Answers

Answer:

D) b < 13 .

Step-by-step explanation:

Given : 3b – 7 < 32 .

To find : Solve this inequality.

Solution : We have given 3b – 7 < 32 .

On adding 7 both sides both sides.

3b < 32 + 7.

3b < 39.

On dividing both sides by 3.

b < 13 .

Therefore, D) b < 13 .

It's a lot like solving equations.

3b-7 < 32
Add 7 to each side.
3b < 39
Divide by 3 on each side.
b < 13

Hope this helps :)

Four light bulbs cost $3.20.how much does it cost to buy 14 light bulbs ?

Answers

SO 14 light Bulbs cost $11.2 or $11.20.

Hope I helped ya!!

3.20= 4 light bulbs
3.20/4= .80cent per light bulb
.80*14=$11.20

The circular ring of the fountain has a radius of 9 feet. what is the area of the ring?a. 4.5 square feet

b. 28.26 square feet

c. 63.61 square feet

d. 254.34 square feet

Answers

The area of the circular ring of the fountain with a radius of 9 feet is approximately 254.34 square feet.

To find the area of the ring, we need to subtract the area of the smaller circle from the area of the larger circle. The area of a circle is given by the formula A = πr^2, where r is the radius of the circle. Therefore, the area of the larger circle is π(9^2) = 81π square feet, and the area of the smaller circle is π((9/2)^2) = 20.25π square feet.

Subtracting the area of the smaller circle from the area of the larger circle, we get:

81π - 20.25π = 60.75π

Using the approximation π ≈ 3.14, we get:

60.75π ≈ 60.75(3.14) ≈ 190.845

Therefore, the area of the ring is approximately 190.845 square feet, which is closest to option (d) 254.34 square feet.
