O A. 270 ft
O B. 150 ft
O C. 120 ft
O D. 180 ft
Set up a ratio with the height over the shadow.
Let the height of the tower be X
The ratio of the tower is x/120
The ratio if the sign is 10/8
Set them to equal and solve for x:
x/120 = 10/8
Cross multiply:
8x = 1200
Divide both sides by 8:
x = 1200/8
x =150
The answer is B. 150 ft.
Answer:
B. 150 feet.
Step-by-step explanation:
The tower and the street sign and their shadows form 2 similar triangles.
So the corresponding lengths are in the same ratio, then:
120 / 8 = h / 10 where h is the height of the tower.
8h = 120 * 10
h = 120 * 10 / 8
= 150 feet.
Solve for s
Hello!
Simplify both sides of the equation
Subtract 3/5s from both sides
Subtract 2 from both sides
Multiply both sides by 5/(-13)
Answer:
s=-55/13
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2−2s=35s+13
2+−2s=35s+13
−2s+2=35s+13
Step 2: Subtract 3/5s from both sides.
−2s+2−35s=35s+13−35s
−135s+2=13
Step 3: Subtract 2 from both sides.
−135s+2−2=13−2
−135s=11
Step 4: Multiply both sides by 5/(-13).
(5−13)*(−135s)=(5−13)*(11)
s=−55/13
