Answer:

451cm cubed

Step-by-step explanation:

The volume of any prism = Area of cross section times height.

So, we substitute area of Cross section with 41 cm squared and height with 11.

41 x 11 = 451

Answer:

B. 10

Step-by-step explanation:

The median is the middle number, so to find it, we must list the numbers from smallest to largest :

5, 5, 8, 11, 15, 21, 27, 34, 55

The median is 15

The mode is what number occurs most often, which is 5.

The difference will be found by subtracting 5 from 15:

15-5=10

Answer:

10

Step-by-step explanation: you have to find the median number and subtract by 5

5,5,8,11,15,21,27,5

also the median is middle number subtract by 5 because it want the difference number of electoral votes per state

15-5=10

Answer:

10( 3/4x  * 9/500y ) = 10  

Step-by-step explanation:

We know 18% can also be found

when we take the x amount 75 x 0.18 = 13.50

We thereafter find 75-13.50 = 61.50 for Janella's hair cost plus $13.50 tip.

But for x = 750 x 9/500 = 10

We find  13.50 = 10

x= 1.5

18% coincidentally is 13.5 and 13.5 x 1.5 = 18

So we could redesign and use 18 in the equation

An equation that could be used to calculate the tip, y, for a bill total of x dollars is y=0.18x.

Given that, Janella has her hair styled and wants to tip her stylist 18%.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the tip be y and total bill be y.

So, tip y = 18% of total bill x

⇒ y = 18% of x

⇒ y = 18/100 × x

⇒ y = 0.18x

Therefore, an equation that could be used to calculate the tip, y, for a bill total of x dollars is y=0.18x.

Short answer yes its true

We would prefer to use a graphing calculator because it will give a more exact solution, because it is easier to read, and because it is faster to do.

There are multiple ways, one of them is by graphing the lines and seeing where the lines intersect.

Now, there are two ways of doing this, graphing by hand and using a graphing calculator.

There are cases where graphing by hand is enough, but is more time-consuming than using a graphing calculator. But there are cases where the intersection happens at a point with irrational values, these cases is really hard to find the solution in a graph by hand (as it can have mistakes and you can't zoom in). While if you used a graphing calculator, you could zoom is as much as you want, so you would get a really good estimation for the solution.

Step-by-step explanation:

Given

[tex](\frac{1}{5})^{-3}[/tex]

Required

Find Equivalent

From law of indices

[tex](\frac{1}{a})^{-x} = \frac{1}{(\frac{1}{a})^{x}}[/tex]

So,

[tex](\frac{1}{5})^{-3} = \frac{1}{(\frac{1}{5})^{3}}[/tex]

Expand denominator

[tex](\frac{1}{5})^{-3} = \frac{1}{(\frac{1}{5})*(\frac{1}{5})*(\frac{1}{5})}}[/tex]

[tex](\frac{1}{5})^{-3} = \frac{1}{(\frac{1}{125})}}[/tex]

Split expression on the right and side

[tex](\frac{1}{5})^{-3} = 1/{(\frac{1}{125})}}[/tex]

Convert divide (/) to multiplication (*)

[tex](\frac{1}{5})^{-3} = 1*{(\frac{125}{1})}}[/tex]

[tex](\frac{1}{5})^{-3} = 1*125[/tex]

[tex](\frac{1}{5})^{-3} = 125[/tex]

Hence, [tex](\frac{1}{5})^{-3}[/tex] is equivalent to 125

Answer:

132 degrees is the measure of angle ABC.

Step-by-step explanation:

ABD = 180 because it is a straight line.

BCD = 48

ABD - BCD = 180 - 48

180 - 48 = 132

Answer:

ABC =132

Step-by-step explanation:

The two angles form a straight line so they add to 180

ABC + 48 = 180

Subtract 48 from each side

ABC +48-48 = 180-48

-To find the distance between points [tex](-8,-2)[/tex] and [tex](-7,-2)[/tex], you the distance formula:

[tex]d = \sqrt{(x_{2} - x_{1})^{2} + ( y_{2} - y_{1})^{2}}[/tex]

-Use the two given points [tex](-8,-2)[/tex] and [tex](-7,-2)[/tex] for the distance formula:

-Then, solve the formula:

[tex]d = \sqrt{(-7 + 8)^{2} + (-2 + 2)^{2}}[/tex]

[tex]d = \sqrt{(1)^{2} + (0)^{2}}[/tex]

[tex]d = \sqrt{1 + 0}[/tex]

[tex]d = \sqrt{1}[/tex]

[tex]d = 1[/tex]

Answer:

Sandy is 9 years old.

Step-by-step explanation:

R+S=24

R=2S-3

R=Randy, S=Sandy

Plug the value of R into the first equation.

2S-3+S=24

Now, simplify.

3S-3=24

Now, solve the equation for S. First add three to both sides.

3S=24+3=27

3S=27

Now divide both sides by 3.

S=9

Based on the information given, the age of Sandy will be 9 years.

The equation that can be used to solve the question will be:

R + S = 24 .... i

R = 2S - 3 ..... ii

Put equation ii into i

R + S = 24

2S - 3 + S = 24

3S = 24 + 3

3S = 27

S = 27/3

S = 9

Therefore, the age of Sandy will be 9 years.
