Negative 18=r-3 What r and how did you get it

Arisa [49]

Ok, so if you’re saying -18=r-3, then first you need to add 3 to each side so you can move the 3 with the -18 so you can isolate r. (Leave it by itself). So now your equation is -18+3=r. Next, combine like terms, so do -18+3, which is -15. Now you have -15=r, so r is equal to -15.

Multiply the radius times pi. 5. A circle has a diameter of 8.2 inches. Find its circumference?

mash [69]

The radius is half the diameter. So do 4.1 times 3.14 for the circumference. :)

how much interest will roxanne have to pay if she borrows $3,000 for 3 years at a simple interest rate of 2%

Darya [45]

Simpe interest rate = PRT/100
— ( principal x rate x time ) / 100

$3,000 is the principal
3 years is the time
2% is the rate

so, PRT/100
(3,000 x 3 x 2) / 100
= $180

Answer : $180

What is the area of this composite shape?

ankoles [38]

Answer:

A. 132 units²

Step-by-step explanation:

The figure has already been broken into chunks, so there is no need to break it up any further.

I'll start with the top left triangle,

Formula for finding the area of triangles: (H x B) / 2

Following this formula, we take the height, 4, and multiply it by the base, 6.

4 x 6 = 24.

Now, we divide the product by 2:

24 / 2 = 12.

We now have the area for the triangle, it is time to move onto the second.

To find the height of the larger triangle, we add 4 and 4 together, giving us 8. To find the base, we subtract 6 from 15, giving us 9.

Now we multiply 8 and 9 together, then divide by 2

8 x 9 = 72

72 / 2 = 36

Now that we've found the area for both triangles, it is time to find the area of the rectangles.

Formula for finding the area of quadrilaterals such as rectangles and squares: L x W

I'll start with the smaller rectangle underneath the top left triangle:

6 x 4 = 24

Now, I'll move onto the bottom rectangle:

15 x 4 = 60

We have the areas of all the shapes in this figure, all we have left to do is to add them together:

60 + 24 + 36 + 12 = 132 units²

132 units² will be your answer.

Help ixl geometry pls !

katovenus [111]

Answer:

Step-by-step explanation:

Since both the triangles are similar, their sides will be in proportion. As one side is getting doubled, by SSS test of similarity, all the other sides will get doubled as well.

As the perimeter of a triangle is sum of its sides, the doubling of all sides will result in doubling of the perimeter.

Hence, perimeter of 2nd triangle = 14 cm.
