Answer:

A. Circumference is 16

C. Diameter is 25.5

Step-by-step explanation:

circumference = 2πr

Diameter = r/2

Diameter = 5 or radius = 5/2

Circumference = 2*3.14*5/2 = 15.7 or 16

Circumference = 80 = 2πr

Radius = 12.74

Diameter = 2*radius = 25.48 or 25.5

What is the answer to 36÷9 using a number line?

Katarina [22]

To divide 36/9 using the number line you have to jump from zero with length of 9 until reach 36, and the result will be the number of jumps.

I do the jumps by steps, but you can draw in the number line:

0. First jump from 0 to 9.

1. Second jump from 9 to 9+9=18.

2. Third jump from 18 to 18+9=27.

3. Fourth jump from 27 to 27+9=36.

4. Great!! We already reach 36.

So, we need four jumps of 9 to reach 36 from 0.

So, the result is 36/9=4

If a car can travel 220 miles on 12 gallons of gas, how many gallons

vampirchik [111]

Set up a ratio of known to unknown:

Let X = the amount of gas needed for 500 miles:

220/12 = 500/x

Cross multiply:

220x = 6000

Divide both sides by 220:

X = 6000 / 220

x = 27.27 gallons (round answer as needed).

Two sides and an angle are given. determine whether the given information results in one triangle, no triangle, three triangles,

Crazy boy [7]

We are given 2 sides 18.7, 16.1 and a NON-included angle.
We have to calculate the altitude of the triangle.
altitude = 18.7 * sine (35)
altitude = 18.7 * 0.57358
altitude = 10.725946 
In this case, side c is greater than the altitude and is less than side a so 2 two triangles will be formed.
