Answer:

q = $0.05

e = $0.5

Step-by-step explanation:

13q = 0.65 equation 1

5q + 7e = $3.75   equation 2

in equation 1, divide both sides of the equation by 13

q = 0.65 / 13 = 0.05

Substitute for the value of q in equation 2

5(0.05) + 7e = 3.75

0.25 + 7e = 3.75

collect like terms

3,75 - 0.25 = 7e

3.5 = 7e

e = 0.5

Answer:

D 0.00000256

Step-by-step explanation:

[tex]5^{28} *5^{-32}*5^{-4}=5^{28-32-4}=5^{-8}=\frac{1}{5^{8}} =0.00000256[/tex]

Answer:

B. 0.000256

Step-by-step explanation:

5^28 . 5^- 32 . 5^ -4

= 5^( 28 - 32 - 4 )

= 5^( 28 - 36 )

= 5^- 8

= 1 / 5^8

= 1 / 390625

= 0.000256

Answer:

10 sides.

Step-by-step explanation:

Two same interior angles + 72 degrees = 360.

Thus, the interior angle of the polygon is [tex]\frac{360-72}{2} =144[/tex].

The formula to find the interior angle of a polygon is [tex]\frac{180(n-2)}{n}[/tex]

[tex]\frac{180(n-2)}{n} =144[/tex]

Multiply both sides by n:

[tex]\frac{180\left(n-2\right)}{n}n=144n[/tex]

[tex]180\left(n-2\right)=144n[/tex]

Expand:

[tex]180n-360=144n[/tex]

Add 360 to both sides:

[tex]180n-360+360=144n+360[/tex]

[tex]180n=144n+360[/tex]

Subtract 144n from both sides:

[tex]180n-144n=144n+360-144n[/tex]

[tex]36n=360[/tex]

Divide both sides by 36:

[tex]\frac{36n}{36}=\frac{360}{36}[/tex]

[tex]n=10[/tex]

Answer:

f(-2) = -17

Step-by-step explanation:

All f(-2) means is to substitute x for -2. Therefore,

2(-2)^3 - (-2)^2 + 3

2(-8) - 4 + 3

-16 - 1

Answer:

The volume of the solid figure = Volume of the first cuboid + Volume of the second cuboid

The volume of the solid figure = 15×5×5 + 5×5×10

Or, The volume of the solid figure = 375 + 250

Or, The volume of the solid figure = 625 inch³

Therefore, the volume of the solid figure = 625 inch³

Answer:

this is quite easy. just count the markings that are not in the 1 ounce or 2 ounce sections. in this problem, there are 5 bottles in total and 2 of them are either in the 1 ounce or 2 ounce section. this leaves 3 bottles. (also make sure you count the ones above and below the areas specified)

Answer:

If you know the area of one triangle, then you can multiply it by 2 to get the area of the parallelogram, because the other triangle is congruent.

Answer: The answer to this question is measure of angle DGE = 1/2 (measure of arc DGE - measure of arc DE).

Step-by-step explanation:

The formula for an angle outside of the arc can be written as measure of angle x is equal to the larger arc starting from the ends of the segments forming x subtracted to the smaller arc starting from the ends of the segments forming x divided by 2.

Answer: The mean is 6.

Step-by-step explanation: First you add all of the numbers together getting a total of 48. Next to find the mean you divide them by the total number of "dots". Lastly, you get the answer of 6 which is your mean.

Answer:

6.

Step-by-step explanation:

First you take the data on the dot plot, and write the numbers down from least to greatest.

The data set:

2,3,6,6,7,8,8,8

Now that you have the data reordered in a easier way to read, add up all the numbers that you got from the dot plot.

2+3+6+6+7+8+8+8=48

Next we count all the number in the data set we made.

2,3,6,6,6,7,8,8,8 = 8

The amount of numbers in this data is 8.

Lastly we then divide 48 by 8.

48/8= 6

So your answer is 6!

Answer:

130

Step-by-step explanation:

Triangle MNP is twice the size of triangle SRP. So 2(x+4)=5x-34.

Distribute: 2x+8=5x-34

Add 34 on both sides: 2x+42=5x

Subract 2x on both sides: 42=3x

Divide both sides by 3: 14=x

If x=14, then 5x-34

is 5(14)-34=70-34=36.

The perimeter of the triangle MNP is

MN+NP+PM.

MN is 36

NP is doubled the 22 because triangle MNP is twice the size of triangle MQS. So NP is 44.

PM is doubled the 25 because triangle MNP is twice the size of triangle QNR. So PM is 50.

The perimeter of the triangle MNP is

MN+NP+PM

=36+44+50

=130
