➷ First, just divide the numbers:
12/4 = 3
When dividing values with exponents, you have to subtract the exponents:
7 - 5 = 2
Therefore, your answer would be option B. 3b^2

Answer:
The height of the water = 6.2 in. to the nearest tenth
Step-by-step explanation:
∵ The rate of flows of water into the tank = 8000 in.³/min.
∴ The volume of the water in the tank after 10 min. = 8000 × 10 = 80000 in.³
∵ The water take the shape of the tank
∴ The height of the water = volume of water ÷ Area of the base of the tank
∵ The tank is cylinder with diameter 128 in. and height 72 in.
∴ The area of the base of the tank = π(128/2)²
∴ The height of the water = 
∴ The height of the water = 6.2 in. to the nearest tenth
Answer:
y = -1/2x + 3.5
Step-by-step explanation:
The gradients of perpendicular lines multiply to make -1. The gradient of the line given is 2, so 2 multiplied by something gives us -1. 2 × -1/2 = -1. The gradient of the perpendicular line is -1/2
y = -1/2x + c
Now we can substitute x = 1 and y = 3 into the equation:
- 3 = -1/2(1) + c
- 3 = -1/2 + c
- c = 3 + 1/2
- c = 3 1/2 or 3.5 or 7/2
The equation of the line is y = -1/2x + 3.5
Hope this helps!
Answer:
10(7q + 6)
Step-by-step explanation:
- Find the GCF of 70 and 60: 10
- Divide each number by 10 (steps shown below)
- 70q ÷ 10 = 7q
- 60 ÷ 10 = 6
- Re-write the expression with 10: 10(7q + 6)
I hope this helps!
Assuming what is meant by "infinite solutions" are infinite number of solutions of a logarithmic equation.
