The area of a rectangular parking lot is 7031m? If the with of the parking lot is 79m, what is its length?
serg [7]
The length of the parking lot is 89m.

To find the length, we can abide by the following formula:

L = A/W

where L is the length, A is the area, and W is the width.

Given this formula, we can set up an equation:

7,031 / 79 = 89

The length of the parking lot is 89 meters.

Find the measure of the indicated angle to the nearest degree
Alisiya [41]

Answer:

The answer to your question is below

Step-by-step explanation:

14) sin Ф = 32/33

    sin Ф = 0.9697

        Ф = 75.86°

15) sin Ф = 16/36

     sin Ф = 0.444

          Ф = 26.39°

16) sin Ф = 29/36

     sin Ф = 0.806

          Ф = 53.66°

17) cos Ф = 11/34

    cos Ф = 0.324

          Ф = 71.12°

18) sin Ф = 21/40

     sin Ф = 0.525

           Ф = 31.67°

19) cos Ф = 6/14

     cos Ф = 0.429

          Ф = 64.62°

20) cos Ф = 38/39

      cos Ф = 0.974

            Ф = 13°

3. What is the scale factor of Figure B to Figure A?
xxMikexx [17]

Answer:

2.5

Step-by-step explanation:

From the diagram, figure B was enlarged to obtain figure A.

The two figures are therefore similar.

The corresponding sides are in the same proportion. That constant value of the proportion is called scale factor.

It is given by:

k =  \frac{image \: length}{corresponding\:object \: length}

Figure B is the image of A

k =  \frac{10}{4}  =  \frac{25}{10}  = \frac{21.5}{8.6} =   2.5

Therefore the scale factor is 2.5
