38.82 if you add them all together they give you 95.25

49.00 + 7.43 + x = 95.25
56.43 + x = 95.25
Subtract 56.43 from both sides
x = $38.82

A surveyor sights the top of a building with a handheld range finder. the top of the building is 148 feet 2 inches away. the ang
Leokris [45]

see the attached figure to better understand the problem


we know that

in the right triangle ABC

cos 56°=AC/AB

where

AC is the adjacent side to angle 56 degrees------> the distance from the surveyor to the building

AB is the hypotenuse-----> 148 ft 2 in

56 degrees------> is the angle of elevation

so

cos 56°=AC/AB---------> solve for AC

AC=AB*cos 56°

AB=148 ft 2 in

convert 2 in to ft

1 ft -----> 12 in

x ft------> 2 in

x=2/12-----> x=0.17 ft

AB=148 ft 2 in-----> 148 ft+0.17 ft------> AB=148.17 ft


AC=AB*cos 56°----> AC=148.17*cos 56°------> AC=82.86 ft


convert 0.86 ft to in

0.86 ft=0.86*12-----> 10.32 in

distance AB=82 ft 10 in


the answer is

the distance from the surveyor to the building is 82 ft 10 in

Answer: 300.

Step-by-step explanation: 225/(No denominator) = 75/100.

225 doesn't go in 75. So, 75/100 divided by 5 = 15/20.

I want to find what number you multiply from 15/20 to get 225/(No

denominator). So, I divide 225 by 15. = 15, so multiply 15 x 15 = 225, and

the denominator, 20 x 15= 300.

(Sorry if you don't understand, I don't really know how to explain things.)

But here's your answer!

What is the y intercept of the function f(x)=2•3^x
kykrilka [37]

Answer:

\boxed{Option \ A}

Step-by-step explanation:

f(x) = 2*3^x

y intercept is when x = 0

So, Putting x = 0 in the above function

=> f(0) = 2*3^0

=> f(0) = 2*1

=> f(0) = 2

So, y-intercept is (0,2)
