P.S - The exact question is -
Given - Mr. Sanders wants to display his American flag in a triangular case as shown below.
To find - What is the area of the triangular case ?
Proof -
Given that,
Base of triangle = 14 2/5 in
Height of triangle = 8.5 in
We know that,
Area of triangle =1/2 *base *height =1/2 *8.5 *14 2/5
=1/2 * 8.5 * 14.4
=1/2 * 122.4
=61.2

we get
The area of the triangular case = 61.2 square inches

(#5) A carpenter has two different-sized circular saws. The smaller saw has the radius shown. I couldn't show it, so it is 1.25 inches. The larger saw has a diameter that is 1.5 inches greater than the diameter of the smaller one. How much greater is the circumference of the larger saw than the smaller saw? Use 3.14 for π. Attach a picture of your work. *

Answers

Answer:

4.71 in. difference

Step-by-step explanation:

so, the radius of the smaller saw is 1.25 and the diameter is double the radius. so it is 2.5 in diameter. the larger saw is 1.5 in greater which is 4 in.

to find circumference, you have to use the solution C = πd or circumference = pi x diameter.

3.14 x 2.5 = 7.85

4 x 3.14 = 12.56

subtract 7.85 from 12.56 to get your answer! i hope this helps!

Answer:

C: y= 1/50x + 4

Step-by-step explanation:

Since margo drove 200 miles to her aunts house and was left with 8 gallons of gas in the tank of her car when she arrived, we just plug the variables we know in the equation to get the answer. she drove 200 miles, so x=200. 1/50x is 1/50 times 200 aka 4. So now we just add the 4 at the end of the equation and 4 + 4 is 8. This is true, we know she had 8 gallons of gas left when she arrived and she drove 200 miles. So C is the correct answer.

C: 1/50x + 4
Therefore the answer should be C...HOPE I COULD HELP GOOD LUCK:))
