47.74

Step-by-step explanation:

Answer:

x=20

Step-by-step explanation:

ok so that is a pentagon and if you didnt know all of the angles in a pentagon add up to equal 540

so we setup an equation which would be

7x+4x+5+4x+10+5x-5+6x+10=540 and now we just solve for x

step 1 combine like terms

7x+4x=11x

11x+4x=15x

15x+5x=20x

20x+6x=26x

5+10=15

15-5=10

10+10=20

now we have

20+26x=540

step 2 subtract each side by 20

20-20 cancels out

540-20=520

now we have 26x=540

the final step is to divide each side by 26

26/26 cancels out

540/26=20

x=20

hope this helps :D

Answer: -46

Step-by-step explanation: Place -7 into the equation. 4(-7-5)+2= 4*-7=-28,-4*5=20. Negative 28 minus 20 is -48. Negative 48 + 2 is -46.

Answer:

x=15 degrees

Step-by-step explanation:

You know that the right angle is split in half to 45 degrees and 3x degrees. Because a right angle is equal to 90 degrees, 3x has to be equal to 45. Therefore, the equation will be 3x=45. You want to make x equal one so you have to divide 3 by each side. The equation will be x=45/3. Simplify that to get x=15. Therefore, x=15 degrees.

Answer:

x = 13

Step-by-step explanation:

(x-1)/(x+2) = 8/10

10(x-1) = 8(x+2)

10x-10 = 8x+16

2x = 26

x = 13

Answer:

B. 117 cm

Step-by-step explanation:

you just multiply them :)

Answer:

117 cm³

(Answer B)

Step-by-step explanation:

The volume is the product of the base area and the height, that is,

V = 13 cm² * 9 cm = 117 cm³

Answer:

a)  $498

b) $1052

c) $554

Step-by-step explanation:

to find the median of lower half of data:  find median of all the data, then find middle value from the minimum value to the median (not including median)

to find the median of upper half of data:  find median of all the data, then find middle value from the median to the maximum value (not including median)

interquartile range (IQR) is the difference of the two

First, order the number set from least to greatest:

3 , 4 , 4 , 7 , 8 , 9 , 12 , 14 , 16 , 20

Mean: You find the mean by combining all the terms, and dividing by the amount of the terms there are in the number set:

(3 + 4 + 4 + 7 + 8 + 9 + 12 + 14 + 16 + 20)/10

(97)/10 = 9.7

Mean: 9.7

Median: You find the median by first ordering the number set from least to greatest, and finding the middle number. Note that if there is a even number of numbers in the set, you find the mean with the two given median digits:

8 & 9 are the median numbers:

(8 + 9)/2 = (17)/2 = 8.5

Median: 8.5

Mode: The mode is the number(s) in the set that shows up the most:

Mode: 4 (shows up one more time than all other numbers)

Range:  The range can be found by subtracting the least number from the greatest number in the number set:

Range: 20 - 3 = 17

Range: 17

Answer:

112*

Step-by-step explanation:

The easy way to figure this out is to take the two numbers we do have and add them together. 50 + 62 = 112

We now now the complete angle if that line was not there in the middle. and sice that angle is the same at angle X it is automatically the same, 112. If you don't understand please comment and let me know.

Answer:

your answer would be 1253in^3

Step-by-step explanation:

there are two boxes

one box has the dimensions 7,5,5

the other has the dimensions 14,11,7

you would have to multiply all the dimensions

7*7*5=175

14*11*7=1078

then you add the two products together

1078+175=1253

hope this helps! have a nice day :)

Answer:

1253in^3

Step-by-step explanation:

7*7*5=175

14*11*7=1078

then you add the two products together

1078+175=1253in ^3

Answer:

you take 2 points on the graph

(3,300) and (6,200)

and then you do y2 -y1

                           x2-x1          

you plug in the values

200-300

6-3               =    -(100)/(3)

every 3 years the resale of a refrigerator decreases by 100 dollars.

its basically the rate that the price goes down for resale value of a refrigerator

Step-by-step explanation:

Let's take the points displayed on this graph:

(300, 3) (200, 6) and (100, 9).

Our first value in the points represents the amount of money for the resale value of a refrigerator, and the second value represents the number of years after the original purchase. So, as we can see, as the years increase, the value goes down $100 dollars every three years.

3 years after original purchase: $300

Increase years by three, value goes down by $100

6 years after original purchase: $200

The rate of change in this situation means that for every  resale three years after the original purchase, the value will decrease by $100.

Answer:

the answers B and D are correct

Answer:

B & D

Step-by-step explanation:

It can-t be A, because that would mean 20², which equals 400, would equal 20.

B is correct because even though it's negative, negative times negative = positive, which would mean that (-sqrt of 20)(-sqrt of 20)=20.

C is wrong because sqrt -20 is an imaginary number,which is a completely different topic.

D is correct because it's the same thing as B, but without the 2 negaties cancelling each other out.

E is the same as A, except it's '-20' x '-20', whcih is still 400, which is still wrong

Hope this helps :)

Answer:

88 ft^2

Step-by-step explanation:

For a rectangular prism with dimensions 1 ft by 8 ft by 4 ft, there are two opposite faces with dimensions

1 ft by 8 ft,

two opposite faces with dimensions

1 ft by 4 ft,

and two opposite faces with dimensions

4 ft by 8 ft.

We find their area and add them.

SA = 2 * 1 ft * 8 ft + 2 * 1 ft * 4 ft + 2 * 4 ft * 8 ft

SA = 16 ft^2 + 8 ft^2 + 64 ft^2

SA = 88 ft^2

Answer:

B) 114.511m^3

Step-by-step explanation:

Formula of a cylinder is πr^2 x h

r = radius (half of diameter)

h = height

Since it is 3/4 full you only do 3/4 of the height so- 0.75 x 9.60 which equals 7.2

Half of the diameter is 2.25. 2.25^2 = 5.0625.

The volume of the cylinder = 5.0625π x 7.2

By solving this, you will get approximately 114.511 m^3 as your answer.

Answer: 8

Step-by-step explanation:

Answer: 8 pizzas.

Step-by-step explanation:If she is ordering 4 pizzas for 15 people then that simply means that the fraction is 4/15, 15*2 is 30, so that means that our next fraction (Equivalent fraction) will be like this 4/15 = -/30. What ever. Happens to the numerator must happen to the denominator and vice versa. So 4*2 is 8. So the answer is 8.

Answer:

Suzy would earn $40

Bill will earn $40

they will both earn $80

Step-by-step explanation:

The total amount suzy earns is a function of the total hours worked. Let t represent time

total income of suzy = $20t eqn 1

Bill's income = starting bonus + variable pay

= $20 + $10t

We are looking for when they would earn the same amount :

20t = $20 + $10t  eqn 2

collect like terms and solve for t

10t = $20

t = 2 hours

Substitute for t in either eqn 1 or 2

20(2) = $40

Suzy would earn $40

Bill will earn $40

they will both earn $80

Answer: The number is 0

Step-by-step explanation:

8 = 7x + 8

Then we solve it:

8 = 7x + 8

8 - 8 = 7x

0 = 7x

0 ÷ 7 = x

x = 0

Answer:

The X- intercept is (7/5,0) and the Y intercept is (0,-21/2)

Step-by-step explanation:

Answer:

25x + 35(2x) = 380

25x + 70x = 380

95x = 380 so

x = 4

then i think that mean it might be 8 then im not completly sure
