A street light is mounted on a pole. The tip of the shadow of a man who is standing on a street a short distance from the pole h
Snezhnost [94]
Suppose
h=height of street light
x=distance of woman from pole, 20-x=distance of man from pole
tan 24=x/h=0.445
tan 28=(20-x)/h=0.532
re-arranging the above we get:
x=0.445h
20-x=0.532h
thus the value of h will be given by:
20=0.977h
hence
h=20.5 ft

substituting the values we get:
x=woman's position =9.1 ft from the pole and the man is 10.9 ft away.

Hi need help on hw plz help me out my questions is - a rectangle has a length of 14cm and width 9.5cm the length increased by 6%
sweet-ann [11.9K]

Answer:

Part a) 21.9\%

Part b) 82.03\%

Step-by-step explanation:

we know that

The original area of rectangle is equal to

A=(14)(9.5)\ cm^{2}

so

if  the length is increased by 6% and the width is by 15%

then

the new area is equal to

A=[1.06(14)][1.15(9.5)]\ cm^{2}

A=(1.06*1.15)(14)(9.5)\ cm^{2}

A=(1.219)(14)(9.5)\ cm^{2}

The new area is (1.219) times the original area

Part a) Calculate the percentage change in area of the rectangle

1.219-1=0.219

convert to percentage

0.219*100=21.9\%

Part b) what is the original area as a percentage of the increased area of the rectangle?

Divide the original area by the increased area

\frac{(14)(9.5)}{(1.219)(14)(9.5)} =\frac{1}{1.219} \\ \\=0.8203

Convert to percentage

0.8203*100=82.03\%
