x is 23

Step-by-step explanation:

cause it is an 180 angle so 180-93=87

87 -18 =69

3x=69

x=23

Answer:

x=23

Step-by-step explanation:

in order to find x

(3x+18)° + 93°=180°

⇒3x+18=180-93

⇒3x=180-93-18

x=69/3

x=23

and there we go X = 23

I did the test and got it correct.

Answer:

the answer is not A. the correct answer is D. 0.00000078

Step-by-step explanation:

The reason D.

is correct is because if you multiply 10 six times you will get 1,000,000

and all you have to do is take the zeros from 1,000,000 and add it to 0.78 you will get your answer.

could someone’s please help me with this

Answers

Answer:

Step-by-step explanation:

first you just divide 11.25 by 9 which is 1.25. then you multiply 5 by 1.25 which is 6.25. Then you do the same with 2, multiply it by 1.25, which is 2.50. for the last one, you divide 20 by 1.25, which is 16

divide 11.25 by 9, and thats 1.25 then multiply it by 2 which is 2.5, so for 2 cartons its 2.5, for 5 cartons its 6.25, and for 20.00 is 16

A hexagonal pyramid has a volume of 144 cubic millimeters and a height of 4 millimeters. What is the area of the base of the pyramid? (Hint: Label the parts you know. Draw a picture if necessary)
This is confusing T^T

Answers

Answer:

The area of the base of the pyramid is 109.2 mm.

Step-by-step explanation:

The area of the base of a hexagonal pyramid is given by the area of a hexagon:

[tex] A_{b} = \frac{P*a}{2} [/tex]  

Where:

P: is the perimeter

a: is the apothem

We need to find the perimeter and the apothem.

The perimeter is equal to:  

[tex] P = 6*s [/tex]

Where:

s: is the side of the pyramid

And the apothem is:

[tex] a = \frac{\sqrt{3}}{2}*s [/tex]

So, to calculate the apothem and the perimeter we need to calculate the side of the pyramid. We can find it from the volume of the pyramid:

[tex] V = \frac{\sqrt{3}}{2}*h*s^{2} [/tex]  

Where:

h: is the height = 4 mm  

V: is the volume = 144 mm³                                  

Then, the side is:  

[tex] s = \sqrt{\frac{2V}{\sqrt{3}*h}} = \sqrt{\frac{2*144}{\sqrt{3}*4}} = 6.5 mm [/tex]

Now, we can find the perimeter and the apothem.

[tex] a = \frac{\sqrt{3}}{2}*s = \frac{\sqrt{3}}{2}*6.5 = 5.6 mm [/tex]

[tex] P = 6*s = 6*6.5 = 39 mm [/tex]

Finally, the area is:

[tex] A_{b} = \frac{P*a}{2} = \frac{39*5.6}{2} = 109.2 mm^{2} [/tex]

Therefore, the area of the base of the pyramid is around 109 mm.

I hope it helps you!

Solve the system using substitution. Show your work.
x = -4y + 9
x - y = 4

Answers

Answer:

please what should we found? is it the value of ×or y

x = -4y + 9
x - y = 4

- rearrange the second equation to x = 4 + y
- then we can plug it into x for the first equation

4 + y = -4y + 9 — then we solve for y
y = -4y + 5
5y = 5 -> y = 1

we can then plug in 1 (our y value) into the original second equation.

x - 1 = 4 -> x = 5

x = 5 & y = 1
you should put it in a coordinate layout so:

Well assuming you don’t need to simplify

44/100

0.44

44%

Step-by-step explanation:

Okay so fraction is easy, theres a 100 cubes in total, 44 are shaded in, 44/100 are shaded in which is the area in this scenario.

Decimal is basically moving the place area by a specific amount, in this case theres no whole number since the whole number is 1 or 100/100 and its 44/100 right now so it can’t be a whole number. Decimals go by tenths, hundreths, thousandths, etc. so in this case 44/100 is n the hundreth place since its over a hundred so its 0.44. Or you can move it twice to the right by the times of 0 that appears.

Percent basically means out of 100. So in this case its 44 out of a hundred or 44%

So in this case it’s 44 out of a 100 or 44%

Can you help plz 7 + 56 y

Answers

I think it's 56y + 7, is what I'm pretty sure of.

Answer:

Simplifying

7 = 56y

Solving

7 = 56y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-56y' to each side of the equation.

7 + -56y = 56y + -56y

Combine like terms: 56y + -56y = 0

7 + -56y = 0

Add '-7' to each side of the equation.

7 + -7 + -56y = 0 + -7

Combine like terms: 7 + -7 = 0

0 + -56y = 0 + -7

-56y = 0 + -7

Combine like terms: 0 + -7 = -7

-56y = -7

Divide each side by '-56'.

y = 0.125

Simplifying

y = 0.125

Mrs. Chevalier’s class is reviewing by playing a math game. Mrs. Chevalier randomly selects an integer from the set of integers -15 to 15.

Part A

What is the probability that Mrs. Chevalier names a positive integer?

Part B

Explain how you determined your answer.

Answers

Answer:

(15/31) ?

Step-by-step explanation:

|-15| = 15

15+15+1 (for 0) = 31

1 through 15 are positive, so 15 of the 31 could be positive, or 15/31

Sorry, could be wrong, but I think it's right

Part A Answer: The probability that Mrs. Chevalier names a positive integer is a 50% chance.

Part B: Numbers from -15 to 15 is thirty-one total numbers including zero, but zero is neither negative nor positive, so it doesn’t really count in this situation unless the instructions describe it as positive. Without the zero, it is thirty numbers in total, with half of them being negative, and half of them being positive, which can also be said as 50%. You can find this answer by dividing 15 by 30, which is 1/2, or 50%.

Step-by-step explanation:

By the Exterior Angle Theorem:

(2x + 1) + 63 = 5x -2

2x + 64 = 5x - 2

66 = 3x

22 = x

Now, we can plug the value of x back into the expression that represents the exterior angle to find the measure of the exterior angle:

5(22) - 2

110 - 2

The answer is 108 degrees. (I'm sorry your question was answered so late; I hope you got the right answer when you solved it!)
