Sindrei [870]

Answer:

Your answer is 5cl

Step-by-step explanation:

This is because of King Henry Died by Drinking Chocolate Milk (Kilometers,Hectometers, Decameters, Base(Liters,Meters, and Grams) Decimeters, Centimeters and Millimeters). So when you have 50 milliliters, milliliters is one place away from centiliters so you move the decimal forward one place.

Find the volume of each sphere. Be sure to include appropriate units.<br> (Show your work)

babunello [35]

Answer:

2145.5m^3

679.2yard

Step-by-step explanation:

$volume \: of \: a \: sphere = \frac{4}{3}\pi \: r {}^{3} \\ when \: r = 8 \\ volume = \frac{4}{3} \times \frac{22}{7} \times 8 {}^{3} \\ volume = \frac{4}{3} \times \frac{22}{7} \times 8 \times 8 \times 8 \\ volume = \frac{4 \times 22 \times 512}{3 \times 7} \\ volume = \frac{45056}{21} \\ volume = 2145.5m {}^{3} \\ \\ for \: the \: second \: shape \\ volume = \frac{4}{3} \times \frac{22}{7} \times 5.5 {}^{3} \\ = \frac{4}{3} \times \frac{22}{7} \times 166.373 \\ = \frac{14641}{21} \\ = 697.2yard$

Tell whether the relation is a function. {(-5, -3), (-1, 3), (4, 3), (8, 8)}

VladimirAG [237]

Given:

The relation is {(-5, -3), (-1, 3), (4,3), (8, 8)}.

To find:

Whether the given relation is a function or not.

Solution:

A relation is called a function, if there exist a unique output for each input.

We have, a relation given as

{(-5, -3), (-1, 3), (4,3), (8, 8)}

Here, all x-values are different. So, each x-value has a unique y-value.

Thus, there exist a unique output for each input.

Therefore, the given relation is a function.

Solve the system of equation?<br>2x - 4y = 10<br>7x - y = 12

allsm [11]

Answer:

x = 1.153846153846154

y = -1.923076923076923

Step-by-step explanation:

Multiply 7x - y = 12 by -4 and then add it to 2x - 4y = 10

2x - 4y = 10

+(-4( 7x - y = 12))

-26x = -30

$\frac{-26x}{-26} = \frac{-30}{-26}$

x = 1.153846153846154

Then plug in x to get y.

2(1.153846153846154) - 4y = 10

2.307692307692308 - 4y = 10

-2.307692307692308 -2.307692307692308

-4y = 7.692307692307692

$\frac{-4y}{-4} = \frac{7.692307692307692}{-4}$

y = -1.923076923076923
