Jake drew an isolsceles triange.
10a. What are the measures of the two acute angles?
10b. How do you know?

Answers

Well, first I need to explain A for you to understand B. 
So, an isosceles triangle has two equal angles. Assuming that the third angle is obtuse, it has to be greater than 90 degrees. 
Now, do 180-91. that equals 89. 89 divided by two equals 44.5. This is an acute angle, and 44.5+44.5+89=180. 180 is the sum of the angles of a triangle

For B, it's honestly just a description of the way you did it. You can use what I did or if you did a different method. 
Sorry it's so late! I hope it's on time!

Mrs. Martin wants to place a ribbon around the outer edge of a rectangular mirror. The area of the mirror is 324 square inches. The width is of the mirror is 12 inches. How many inches of ribbon does Mrs. Martin need?

Answers

The inches of ribbon that Mrs. Martin needs will be equal to the perimeter of the rectangular mirror.

We know that the area of a rectangle equals the length times the width.

Area = length * width
324 square inches = length * 12 inches
length = 27 inches

The perimeter of a rectangle is two times the length plus two times the width.

Perimeter = length + length + width + width
Perimeter = 27 + 27 + 12 + 12 
Perimeter = 54 + 24 
Perimeter = 78 inches

Therefore, Mrs. Martin needs 78 inches of ribbon.

15% of Alina’s workout consisted of cardio exercise. 25% of Dane’s workout consisted of cardio exercise. Which statement must be true?If they worked out for the same amount of time, Dane did 10 more minutes of cardio exercise than Alina.


If Alina’s workout was 80 minutes, and Dane’s workout was 48 minutes, they spent the same amount of time on cardio exercise.


If both workouts were 60 minutes, Dane spent 8 more minutes on cardio exercise than Alina did.


Alina spent less time on cardio exercise than Dane did.

Answers


The correct answer is B. If Alina’s workout was 80 minutes, and Dane’s workout was 48 minutes, they spent the same amount of time on cardio exercise.

To figure this out, first find 15% of 80 and then 25% of 48.

To find 15% of 80, you can first find 10% of 80 which is 8(just move the decimal one place to the left). The remaining 5% will be half of 8 since 8 is 10%. Add both the numbers up and you will get 12. (8+4=12)

To find 25% of 48, you can divide 48 by 4. Since percent means 'out of 100', 25% is 25 of 100. 100 divided by 25 is equal to 4. So, 48 divided by 4 is equal to 12.

So, the final answer is B. They both equal to 12.

Hope it helps :)

The correct answer is c. -1/2~
you can say -2/3 = -4/6 so : 1/6 - 4/6 = -3/6 = -1/2 and thats the simplest so the answer is c :))

If each number were multiplied by four, their sum would be 172. What are the two numbers?

Answers

There are a lot of choices for the two numbers; this is because no other condition has been placed on the numbers to pinpoint the exact numbers required.

x = 1st number
y = 2nd number

The equation would be:  
4(x+y) = 172

4(x+y)/4 = 172/4
x + y = 43

If we get the value of x. then, x = 43 - y
Substitute x by its value

43 -y + y = 43
43 = 43
y = 0 

If y = 0 then x = 43 to get the sum of 43
 
  x       y      x + y      4x        4y        4x + 4y
