Margo sells bracelets for $8 each and necklaces for $12 each. The equation below can be used to calculate E , her total earnings. E=8b+12n If is the number of bracelets, and n is the number of necklaces she sold, which equation can be used to find b , when E and n are known?

Answers

Answer 1

The equation that can be used to find b, when E and n are known is: b = (E - 12n) / 8.

This equation can be derived from the original equation of E=8b+12n. To solve for b, we can start by subtracting 12n from both sides of the equation to isolate b. We then divide both sides of the equation by 8 in order to solve for b.

The result is b = (E - 12n) / 8. This equation can be used to find the number of bracelets (b) when the total earnings (E) and the number of necklaces (n) are known.

We can rearrange the equation to solve for b.

E = 8b + 12n

Subtract 12n from both sides:

E - 12n = 8b

Divide both sides by 8:

(E - 12n)/8 = b

Therefore, the equation to find b, when E and n are known, is:

b = (E - 12n)/8

Step-by-step explanation:

brainliest please?

Answer:

336703275

Step-by-step explanation:

This is simple multiplication:

When you 'multiply' or 'times' a number you add it to itself a number of times, for example, 8475 multiplied by 39729 is the same as saying 8475 +8475 + 8475 = 336703275. Multiplication is therefore a quicker way of adding the same number many times, for example, 8475 x 39729 = 336703275.

What is a cylinder?

In geometry, it is defined as the three-dimensional shape having two circular shapes at a distance called the height of the cylinder.

We know the volume of the cylinder is given by:

[tex]\rm V = \pi r^2 h[/tex]

We have:

Water flows at a rate of 6500 cubic inches per minute into a cylindrical tank.

Volume or amount of water after 5 minutes:

= 6500×5

= 32500 cubic inches

The base area of the cylindrical tank = πr²

r is the radius of the tank

The diameter of the tank = 120 inches

The radius r = 120/2 = 60 inches

The base area of the cylindrical tank = π(60)² = 79200/7

∵ π = 22/7

The height of the water in the tank after 5 minutes

= 32500/(79200/7)

h = 2.87 inches

Thus, the height of the water in the tank after 5 minutes is 2.87 inches if the tank has a diameter of 120 inches and a height of 72 inches.
