Answer:

The answer is 26

Step-by-step explanation:

All we do is multiply 4/8 by 52.

52 = 52/1

52/1 * 4/8 = 208/8

208/8 = 26

So the answer is 26.

Hope this helps! :)

Suppose that water is pouring into a swimming pool in the shape of a right circular cylinder at a constant rate of 8 cubic feet
adell [148]

Answer:

dh/dt = 0,07 ft/min

Step-by-step explanation:

The swimming pool has the shape of right circular cylinder, therefore its volume is

V(c) = π*x²*h

Where x is the radius of the base and h the height

We take differentiation on both sides of the equation to get:

dV/dt  =  π*x²*dh/dt

The rate of change in height of water in the pool, is independent of the height of the water, since the pool is a right crcular cylinder, and dV/dt is constant at 8 ft³/min.

Then:

8  = π*x²*dh/dt

dh/dt = 8 /  π*x²

dh/dt = 8/113,04

dh/dt = 0,07 ft/min

Please help me solve this?
jenyasd209 [6]

Recipe is for 24 pieces, and required quantity is 16.

So the ratio is 16/24 = 2/3 means we need to reduce all ingredients to 2/3 of the given quantities. Not all recipes can be reduced prorata, but we will assume it can be done. A word of caution: the measurement of quantities will become awkward (like 3/8 of a teaspoon of salt, etc). The practical way is to make the full recipe, and invite friends to take home the remainder.

Here's the scaled recipe

Butter 1cup*3/4 = 3/4 cup

unsweetened chocolate = 4*3/4 = 3 squares

white sugar = 2 * 3/4 = 1 1/2 cups

eggs = 4 * 3/4 = 3 eggs

A.P. flour = 1 cup * 3/4 = 3/4 cups

vanilla extract = 1 * 3/4 = 3/4 teaspoons

salt = 1/2 * 3/4 = 3/8 teaspoons

chopped walnuts = 2 * 3/4 = 1 1/2 cups


For this reason, there is a trend to use weights (in grams) than volumes to make scaling recipes easier.

25.3 = s + 6.2<br><br> s= unknown
den301095 [7]

Answer:

s = 19.1

Step-by-step explanation:

Simplifying

25.3 = s + 6.2

10011813 avatar

Solving

25.3 = 6.2 + s

Solving for variable 's'.

Move all terms containing s to the left, all other terms to the right.

Add '-1s' to each side of the equation.

25.3 + -1s = 6.2 + s + -1s

Combine like terms: s + -1s = 0

25.3 + -1s = 6.2 + 0

25.3 + -1s = 6.2

Add '-25.3' to each side of the equation.

25.3 + -25.3 + -1s = 6.2 + -25.3

Combine like terms: 25.3 + -25.3 = 0.0

0.0 + -1s = 6.2 + -25.3

-1s = 6.2 + -25.3

10011813 avatar

Combine like terms: 6.2 + -25.3 = -19.1

-1s = -19.1

Divide each side by '-1'.

s = 19.1

Simplifying

s = 19.1
