Answer:

x = 11

Step-by-step explanation:

interior angles of a triangle = 180

equation:

⇒ 82 + 31 + 6x + 1 = 180

combine like terms:

⇒ 82 + 31 + 6x + 1 = 180

⇒ 114 + 6x = 180

subtract 114 on both sides:

⇒ 114 - 114 + 6x = 180 - 114

⇒ 6x = 66

divide 6 on both sides:

⇒ 6x = 66

⇒ [tex]\frac{6x}{6} = \frac{66}{6}[/tex]

⇒ x = 11

Answers

Answer:

A.) 11%

Step-by-step explanation:

Step 1) There are 9 favorable outcomes but only 1 outcome is possible, so that leaves us with a fraction of: [tex]\frac{1}{9}[/tex]

Step 2) Then we need to turn this into a decimal to find the percentage:

1 ÷ 9 = 0.111111111...

Step 3) We now need to turn this into a percent:

0.11 x 100% = 11%

Use the net to find the surface area of the cylinder. 6ft and 7ft

Answers

Answer:

A. 84 pi feet^2

Step-by-step explanation:

So the lateral area is the rectangular piece on the net

In order for it to be an actual cylinder the 2 circles are congruent

Therefore the radi, area, circumference ect.. are the same.

So the only missing measurement we need to find the lateral area is the length of the rectangular piece

If you visualize a cylinder, the rectangular piece goes around the perimeter/circumference of the circle

So that means that the length of the rectangle is the circumference of the circle

Circumference = 2*pi*r

2 * pi * 6

= 12 pi

Then 7*12 pi

=84 pi

So the lateral area is 84 pi

A very large bag contains more coins than you are willing to count. Instead, you draw a random sample of coins from the bag and record the following numbers of each type of coin in the sample before returning the sampled coins to the bag. If you randomly draw a single coin out of the bag, what is the probability that you will obtain either a quarter or a penny

Answers

Missing Details

Quarters  ≡ Dimes ≡  Nickels ≡  Pennies

23             ≡   29      ≡  17           ≡  38

Answer:

[tex]P(Q\ or\ P) = 0.5701[/tex]

Step-by-step explanation:

Given

[tex]Quarters = 23[/tex]

[tex]Dimes = 29[/tex]

[tex]Nickels = 17[/tex]

[tex]Pennies = 38[/tex]

First, we calculate total number of coins

[tex]Total = 23 + 29 + 17 + 38[/tex]

[tex]Total = 107[/tex]

The probability of obtaining quarter (Q) of penny (P) is:

[tex]P(Q\ or\ P) = P(Quarters) + P(Pennies)[/tex]

[tex]P(Q\ or\ P) = \frac{n(Quarters)}{Total} + \frac{n(Pennies)}{Total}[/tex]

Take LCM

[tex]P(Q\ or\ P) = \frac{n(Quarters) + n(Pennies)}{Total}[/tex]

[tex]P(Q\ or\ P) = \frac{23 + 38}{107}[/tex]

[tex]P(Q\ or\ P) = \frac{61}{107}[/tex]

[tex]P(Q\ or\ P) = 0.5701[/tex]

Samantha’s annual college tuition is $18,541.89. The college offers a monthly payment plan of 9 equal payments. How much would each monthly payment be?

Answers

i think 2,057.21 because 18,541.89 divided by 9 is 2,057.21

Answer:

18541.89/9 = $2060.21 is the answer

Step-by-step explanation:

Total college tuition = $18541.89

Number of equal payments = 9

Equal payments = 18541.89/9

                           = $2060.21

D. A trapezoid has 4 right angles but a parallelogram doesn't need to have 4 night angles
8 07 13 Answered

Answers

Answer:

(a) A trapezoid has only 1 pair of parallel sides but a parallelogram has 2

Step-by-step explanation:

Required

The difference between a trapezium and a parallelogram

The major difference is:

A trapezium has a pair of parallel side, the other sides are not parallel

A parallelogram has 4 sides where opposite sides are parallel (i.e 2 pairs of parallel sides).

Hence, (a) is correct

The slope indicates that the height ? feet per minute.

Answers

The distances in length and height and the total have the same unit (e.g. feet or meters). When the slope is decreasing, height and slope have a minus as prefix.

if you were a doughnut shop owner and wanted to find out which doughnut you should make more of, which measure of central tendency would you use.​

Answers

Answer:

Mode

Step-by-step explanation:

Measures of central tendency:

The 3 most common measures of central tendency are: The mean, the median, and the mode.

The mean is the average value.

The median separates the lower 50% of the values from the upper 50% of the values.

The mode is the value that appears the most times in the data-set.

In this question:

To find the doughnut you should make more, you should have to know which has the biggest interest from clients, that is, the one that is sold the most, which means that the mode should be used.

Mode
