Answer:

$59.40

Step-by-step explanation:

8% is equal to 0.08

since you are adding the tax to the original cost you will multiply 55 by 1.08 to get the cost of the shoes plus the tax.

AlekseyPX

Answer:

Height of plane = 25971.7 meters

Step-by-step explanation:

let H =height of plane

Let x = distance ray to the point under the plane

800 foot = 245meters

1 mile = 1609meters.

Tan 81 = \frac{H}{1609+x}    -----------------------(1)

Tan 67 = \frac{H-245}{x}    -----------------------(2)

6.3134  = \frac{H}{1609+x}   ------------------------(3)

2.3556 =  \frac{H-245}{x}    -----------------------(4)

from (3) and (4)

H = 10158.26 + 6.3134x  ---------------(a)

H = 245 + 2.2336x ---------------(b)

equating both (a) and (b) we have:

9913.26 = 3.9576x

x = 2504.74

Subst. x = 2504.74 into (a)

H = 25971.7meters
