Answer:

9

Step-by-step explanation:

12.5/100 = 0.125

Since there were 2 zeros, we took the point 2 places back.

0.125 in fraction = 1/8

1/8 x 72/1 = 9/1

= 9

Answer:

A. 9

Step-by-step explanation:

% = 1\100

SO..

12.5% = 12.5\100

the word 'of' is the same as the mathematical multiply.

12.5\100 x 72 = 9

The second side of a triangular deck is 3 feet longer than the shortest side and a third side that is 3 feet shorter than twice
matrenka [14]

Answer:

Shortest Side = 20 feet

Second Side = 23 feets

Third Side = 37 feets

Step-by-step explanation:

Let the shortest side of the desk be x. Hence,

Second side = (x + 3) feets

Third side = (2x - 3) feets

Perimeter = 80ft

x + (x + 3) + (2x - 3) = 80

                          4x = 80

                             x = 20

Hence, Second side = (20 + 3) feets

                                  = 23 feets

Third side = (40 - 3) feets

                 = 37 feets

Hence<u>,</u><u> shortest side is 20 feets, Second side is 23 feets, Third side is 37 feets.</u>

Lines Line D E and Line A B are parallel. Lines D E and A B are parallel. Angles B and D are alternate interior angles. Which an
valina [46]

Answer:

a. angles A and C

b. angles B and D

Step-by-step explanation:

When two lines are parallel, it implies the value of the angle between them is 180^{0}. Thus the lines can not meet when extended continuously.

Alternate angles are two equal angles that lie on opposite sides of the transversal line. Alternate Interior Angles are a pair of equal angles on the inner side of two parallel lines.

Since lines DE and AB are parallel with alternate interior angles at B and D, then angles A and C with angles B and D are alternate interior angles.

i.e         < A = < C (alternate interior angle property)

            <B = < D (alternate interior angle property)
