A cell phone tower in a field casts a shadow of 100 ft. At the same time, a 4 ft 6 in post near the tower casts a shadow of 3 ft
Volgvan
This is the concept of linear proportionality;
We are required to find the height of the tower in feet. The height of the tower will be found as follows;
[height of tower]/[length of the shadow of tower]=[height of post]/[length of shadow of the post]
height of the tower =h
height of the shadow=100ft
height of post=4 ft 6in=4 1/2 ft= 9/2 ft
length of the post's shadow=3 ft 4 in 3 1/3 ft=10/3 ft

N/B 1 ft= 12 inches

thus;
h/100=(9/2)/(10/3)
multiplying both sides by 100 we get:
h=(9/2)/(10/3)*100
h=9/2*3/10*100
h=135 ft

the answer is 135 ft

How do I answer A and B?
shusha [124]

Answer:

Step-by-step explanation:

a) We're working with the ratio 3:1

x:500

500/1 = 500

500 * 3 = 1,500

x = 1,500

She would need to use 1,500 mL of yellow ink.

b) We're working with the ratio 2:3

x:750

750/3 = 250

250 * 2 = 500

x = 500

She would need to use 500 mL of red ink.

You can check both of these by:

(a) 1,500/500 = 3/1 = 3 : 1 which is the ratio we're working with.

(b) 500/2 = 250

750/2 = 375

250 : 375

Then, divide both 250 and 375 by 125

250/125 = 2

375/125 = 3

We are then left with the ratio 2 : 3 which is the ratio we're working with.
