I Did Ah Little Digging Down Deep And The Answer I Came Up With Was 81 .

Answer:

81.

Step-by-step explanation:

in order to find 8.1×10, you'd want to move your decimal place one to the right (hence the ONE zero on the end of 10). so, if you wanted to do 8.1×10, it would be 81.

if you wanted to do 8.1×100, it would be 810 because you'd move the decimal place two to the right (because there are two zeroes on the end of 100)

if you wanted to do 8.1×1,000, your answer would be 8,100. moving the decimal place three to the right (hence the three zeroes on the end of 1,000) you'd get 8,100.

Hope this helps! <3

David wants to measure the width of a road
alexira [117]

Answer:

<u>The width of the road =  25.359 m</u>

Step-by-step explanation:

See the attached figure which represents the problem.

The length of AB = 40 m

let the width of the road w.

Construct PC perpendicular to AB, So, the measure of angle C = 90°

∠B = 60° and ∠A = 45°

Let the length of AC = x, so, the length of BC = 40-x

At ΔBCP which is a right triangle at C

tan B = opposite/adjacent = w/(40-x)

w = (40-x) * tan B  ⇒(1)

At ΔACP which is a right triangle at C

tan A = opposite/adjacent = w/x

w = x * tan A  ⇒(2)

from (1) and (2)

(40-x) * tan B = x * tan A

40 tan B - x *tan B = x tan A

40 tan B  = x tan A + x *tan B

40 tan B  = x (tan A + tan B)

x = (40 tan B)/(tan A + tan B) = (40 tan 60)/(tan 60 + tan 45) = 25.359 m

substitute at (2) with x

w = x tan A = 25.359 tan 45 = 25.359 m

<u>So, The width of the road =  25.359 m</u>
