Wheel world sold 875 cars last year if the sales this year are 120% of sales last year how many cars will they sell this year

inn [45]

okay so first you wanna turn that 120% into a decimal and the decimal form of that would be 1.2 or 1.20

Secondly you want to multiply 875 by the 1.2

875*1.2 = 1050

So if they sell 120% of last years sales they will sell 1050 cars this year.

Hope this helped :)

Two people are standing on opposite sides of a hill. Person A makes an angle of elevation of 65° with the top of the hill and pe

See the picture to better understand the problem

we know that
in the triangle ABC
∠A+∠B+∠C=180°
find ∠C
∠C=180-[80+65]------> ∠C=35°

Applying the law of sines

AB/sin C=CB/sin A
solve for CB
CB=AB*sin A/sin C-----> CB=45*sin 65/sin 35-----> CB=71.10 ft

the answer is
<span>the distance from person B to the top of the hill is 71.10 feet</span>
