1) What is the scale of a drawing in which a 9ft wall is 6 cm long?

2) Using a ¼ in. = 1 ft. scale, how long would a drawing of a 22 ft car be?

3) The height of a person on a scale drawing is 4.5 in. The scale is 1:6. What is the actual height of the person?

The scale of a map is 1 in. = 21 mi. Find each length of the map.
4) 147 mi = 5) 5.25 mi. =

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.
