Answer:

the answer is b

Step-by-step explanation:

Answer: B

Step-by-step explanation:

The second power basically means that you multiply the number by itself that many times depending on the power, and since it's 50^2, the answer is Caleb - 100 | Jenna - 2,500. (Tip: Just multiply 50 x 50)

Complete Question:

Luke, Kira, and Ali each served 2/3 of their own cake. Each cake was the same size, but Luke served 4 slices, Kira served 6 slices, and Ali served 8 slices. How is this possible? Enter your answers in the boxes to complete the solution.

A. Luke cut his cake into how many slices?

B. Kira cut her cake into how many slices?

C. Ali cut her cake into how many slices.

Answer:

A. 6 slices.

B. 9 slices.

C. 12 slices.

Step-by-step explanation:

Given the following data;

Number served by Luke = 4 slices

Number served by Kira = 6 slices

Number served by Ali = 8 slices

We would solve for the number of slices each of them divided their cakes into.

For Luke, serving 2/3;

[tex] \frac {4}{\frac{2}{3}} = \frac {4 * 3}{2} [/tex]

[tex] \frac {4}{\frac{2}{3}} = \frac {12}{2} [/tex]

[tex] \frac {4}{\frac{2}{3}} = 6 \; slices [/tex]

For Kira, serving 2/3;

[tex] \frac {6}{\frac{2}{3}} = \frac {6 * 3}{2} [/tex]

[tex] \frac {6}{\frac{2}{3}} = \frac {18}{2} [/tex]

[tex] \frac {6}{\frac{2}{3}} = 9 \; slices [/tex]

For Ali, serving 2/3;

[tex] \frac {8}{\frac{2}{3}} = \frac {8 * 3}{2} [/tex]

[tex] \frac {8}{\frac{2}{3}} = \frac {24}{2} [/tex]

[tex] \frac {8}{\frac{2}{3}} = 12 \; slices [/tex]

Therefore, it is possible because;

A. Luke cut his cake into 6 slices.

B. Kira cut her cake into 9 slices.

C. Ali cut her cake into 12 slices.

Given:

The data values are 45, 41, 35, 44, 38, 47, 47, 39, 37, 43, 42.

To find:

The interquartile range of these test results.

Solution:

We have, the set of data values.

45, 41, 35, 44, 38, 47, 47, 39, 37, 43, 42

Arrange the data in ascending order.

35, 37, 38, 39, 41, 42, 43, 44, 45, 47, 47

Divide the data in two equal parts.

(35, 37, 38, 39, 41), 42, (43, 44, 45, 47, 47)

Divide each parenthesis in two equal parts.

(35, 37), 38, (39, 41), 42, (43, 44), 45, (47, 47)

Here,

First quartile: [tex]Q_1=38[/tex]

Third quartile: [tex]Q_3=45[/tex]

Now, the interquartile range is

[tex]IQR=Q_3-Q_1[/tex]

[tex]IQR=45-38[/tex]

[tex]IQR=7[/tex]

Therefore, the interquartile range of these test results is 7.

Answer:

x<8

Step-by-step explanation:

i don't think the question was complete, i cannot make an inequality with just the information given.

Given:

One endpoint of a line segment = (-7,-9)

Midpoint of the segment = (-2,-16)

To find:

The other endpoint of the given line segment.

Solution:

Let (a,b) be the other endpoint of the given line segment.

Midpoint formula:

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

Using this formula, we get

[tex](-2,-16)=\left(\dfrac{-7+a}{2},\dfrac{-9+b}{2}\right)[/tex]

On comparing both sides, we get

[tex]\dfrac{-7+a}{2}=-2[/tex]

[tex]-7+a=-4[/tex]

[tex]a=-4+7[/tex]

[tex]a=3[/tex]

And,

[tex]\dfrac{-9+b}{2}=-16[/tex]

[tex]-9+b=-32[/tex]

[tex]b=-32+9[/tex]

[tex]b=-23[/tex]

Therefore, the coordinates of other endpoint are (3,-23).

Answer:

20 oatmeal cookies

Step-by-step explanation:

4/5 of 25 is 20

If you are working on proportions, you can do 4/5=x/25

Answer:

24

Step-by-step explanation:

30 cookies, 4/5 are oatmeal

Multiply fractions straight across the equation, numerator times numerator and denominator times denominator.

30/1 x 4/5 = 120/5

Reduce 120/5 by dividing denominator and numerator by 5

120 / 5 = 24/1 = 24 cookies were oatmeal.

OR

30/5 = 6 = 1/5 of 30

4 x 6 = 24 cookies were oatmeal

Answer:

x = 12

Step-by-step explanation:

In similarity triangles angles are congruent.

∠D = ∠A

x² - 8x = 48

x² - 8x  - 48 = 0

x² + 4x  - 12x - 48 = 0

x(x + 4) - 12(x + 4) = 0

(x +4)(x - 12) = 0

x - 12 = 0     {Ignore x + 4 = 0, as measurements won't have negative values}

x = 12

Answer:

x = 23

Step-by-step explanation:

(8x - 27) and (7x - 4) are corresponding angles and are congruent, so

8x - 27 = 7x - 4 ( subtract 7x from both sides )

x - 27 = - 4 ( add 27 to both sides )

x = 23

Answer:

x = 23

Step-by-step explanation:the answer to your question is 3/28

Answer:

3/28 or [tex]\frac{3}{28}[/tex]

Step-by-step explanation:

[tex]\frac{2}7}[/tex]÷[tex]\frac{8}{3}[/tex]

to divide fractions, flip the second one and multiply them.

[tex]\frac{2}{7}*\frac{3}{8}[/tex]

2 * 3 = 6

7 * 8 = 56

[tex]\frac{6}{56}[/tex]

simplify by dividing both sides by 2

[tex]\frac{3}{28}[/tex]

Answer:

2

Step-by-step explanation:

8:400*100 =

(8*100):400 =

800:400 = 2

The solution of the equation that 8 is what percent of 400 is  2, i.e. 8 is 2  percent of 400.

Two algebraic expressions separated by an equal symbol in between them and with the same value of the expression are called equations.

Example = 2x +4 = 12

here, 4 and 12 are constants and x is variable.

The equation of percentage can be calculated as:

Consider, the unknown variable as x,

According to the given data in the question,

[tex]8 = \dfrac{x}{100} \times 400[/tex]

The equation can be simplified as:

8 = 4x

Divide both side by 4 to get the value of x,

x = 2

The solution of the equation that 8 is 2  percent of 400.
