Answers

Answer:

If I am correct it is either 344 degrees or 172 degrees because the highlighted area only takes over half of the circle meaning it has to be 172 or 344 as it is the only numbers over or close to 180 degrees

I have a triangle: Angle A = 3x +28; Angle B = 5x +52; Angle C = 2x - 10: Solve for X

Answers

I have no clue if I even did this right but here’s my work. I don’t wanna get it wrong for you!
Answer: x=11


Explanation: The anglers in a triangle must all add to 180.

Therefore, we can use the equation 180=3x+28+5x+52+2x-10

Combing like terms gives us 180=10x+70

Solving for x gives us 11.

To check our work, we can plug in 11 for x.

3(11)+28+5(11)+52+2(11)-10=180.

Create a table of values for Jackson's situation described above. Is the table proportional? How do you know?​

Answers

x represents the number of weeks he has been saving.

y is the total money in his account.

The slope is $15

The y intercept is 35

For the table

X:0 and y: 35, x:1 y:50, x:2 y:65, x:3 y:80 x:4 y:95 , x:5 y:110 ,

This table is not proportional because the equation you have has a y intercept and for it to proportional it has to be written as y=mx not as y=Mx+b

Is not proportional table

Find the percent of change from 6,570 pt to 16,425 pt.

Answers

Answer:

Percentage Change | Increase and Decrease

First: work out the difference (increase) between the two numbers you are comparing.

Increase = New Number - Original Number.

Then: divide the increase by the original number and multiply the answer by 100.

% increase = Increase ÷ Original Number × 100.

Step-by-step explanation:

hopefully this helped and you can find the percent change.

I think you would do
6,570 divided by 16,425
And that would get you
0.4%

not sure if this is correct i did my best

Answer:

The answer is 0.045

Step-by-step explanation:

1. Use this formula V=lwh

0.5 x 0.4 x 0.15 = 0.03

That is the volume of the lower prism

2. Do V=lwh again for the volume of the upper prism

0.5 x 0.15 x 0.2 = 0.015

3. After that add both of them up together

0.015 + 0.03 = 0.045

4. Trust me I got this right in Khan academy and am confident wiht this answer.

Hi I need help with this problem. But it has to be shown with work. Does anyone know?
x : 6 = 10 : 150

Answers

Answer:

its is 90

Step-by-step explanation:

6x10=60    150-60=90

Answer:

0.4 or 2/5???

Step-by-step explanation:

I believe this is a proportion/ratio problem.

Think of it like this:

x/6 = 10/150

To solve for x, you must cross multiply:

150x = 6*10 (150x... DON'T write 150*x, that is nonsense)

150x = 60

     x = 60/150  (you divide because you are actually dividing 150 on both sides and doing the opposite operation of multiplication)

     x = 6/15

     x = 2/5 or 0.4  (I simplified it)

Hopefully this helped? I can't seem to find a whole number answer... so the only options I could do are 2/5 or 0.4

please help I don't understand I don't want the answer I want an explanation

Step-by-step explanation:

I already explained this in the "ask [insert name here] about this question" thing, but out of the goodness of my heart I can do it once more. Just take random 2 coordinates and take the difference of the y values and divide it by the difference of the 2 x coordinates. Simple! Any more questions just ask me on this or DM me

2. Now you need to find how many cubes are needed to fill it. Basically since it takes 8 1/2 cm cubes to fill a 1 cm cube, you need to multiply 8 by 13 1/8. I got 105.

The answer is D. I’m assuming this is surface area so here’s my explanation:) ok so the area of the triangle is 6 (4x3 divided by 2) and when you add the other triangle that’s 12. Ok so we have 12 so far. Then the area of the bottom rectangle is 24 (3x8). Then the area of the side rectangle is 32 (4x8). THEN the top rectangle’s area is 40 (8x5). When you add the numbers up (12+24+32+40) you get 108! And of course dont forget the cm2. ( centimeters squared ). :) I hope this helps
