Carl has three lengths of cable, 5/6 yard long, 1/4 yard long, and 2/3 yard long. If he uses 1 yard of cable, how much cable is left?
Please explain how you did it :3

Answers

Answer 1
He would have 9/12 yards left over because you have to create a common denominator which would be 12. so for 5/6 you would multiply by 2 so you have 10/12. 1/4 you have to multiply by 3 so you get 3/12. and 2/3 you have to multiply by 4 so you get 8/12. then you add them 10/12+3/12+8/12 = 21/12 which simplifies to 1 9/12 and because he used 1 yard he is left with 9/12.
final answer: 9/12 yards

On a large baking tray, 40 cookies can be baked together. To bake 40 cookies it takes 14 minutes, for baking 80 cookies it takes 28 minutes, for baking 100 cookies it takes 42 minutes. How much time will it take to bake 140 cookies?

A-49 B-56 C-57 D48

Answers

the answer is B (56) because it states that it takes 14 minutes to bake 40 cookies, and you already have 100 cookies so you would just add the time it took to bake 40 cookies which would be 42+14=56

Find the area of the shaded region please help

Answers

To solve this problem I'd reccomend first finding the area of the circle, then dividing that area by 4 to find the area of the shaded area.

Let's begin!

To find the area of a circle, we will use this formula:

A = (pi) r^2

(pi multiplied by the radius squared)

The radius of a circle is the distance from the center outwards. The diameter goes straight across the circle, through the circle. Radius is basically half of a circle's diameter.

The math problem states that we approximate pi to be 22/7, so we will use that in place of the pi symbol.

Finding the area of the circle:

(pi) r^2 = A

(Write out formula)

(22/7) 12^2 = ?

(Input the values that we now, r equals 12 because that is the radius shown on the image the problem provided.)

22/7 × 144 =

(Start solving, we did 12^2 first)

452 4/7 in^2 (inches squared or square inches)

(Always use your units, math teachers usually don't allow naked numbers. You'll notice that our answer is in fraction form, that's okay if it is, unless your teacher says otherwise, because some teachers prefer answers in decimal form rather than in fraction form)

Now that we know the whole area of the circle, we can finally find the area of the shaded region :)

452 4/7 ÷ 4 = 113 1/7 in^2 (square inches or inches squared)

The area of the shaded region is 113 1/7 in^2

(Hope this helps :) )

The Area is 113/7 in
