A pyramid has a square base with an area of 169ft. What is the perimeter of the base of the pyramid?

ArbitrLikvidat [17]

Answer:52 ft.

Step-by-step explanation: If the area of the base of the pyramid is

169

then each side of the base is

long because the base of the pyramid is a square.

Length of the side,

√

169

Iif we take the area of a square

where

we get the area of the base to be

169

thus proving that each side of the base is

long.

So to find the perimeter of the base of the pyramid we use the formula:

where

and thus,

Working alone and at a constant rate, Machine A takes 3 hours to create a widget. Machine B, working alone and at a constant rat

PilotLPTM [1.2K]

Answer:

Time required by Machine B to create a widget = 4 hours

Step-by-step explanation:

Time taken by Machine A ( $T_{A}$ ) = 3 hours

Time taken by Machine B ( $T_{B}$ )= x hours

Time taken by both machines by working together = 12 hours

The time required to both machines by working together to finish a task is given by the formula = $\frac{T_{A} {T_{B} } }{T_{A} + T_{B} }$

Put the values in above formula we get

⇒ T = $\frac{3 x}{3 + x}$

⇒ 12 = $\frac{3 x}{3 + x}$

⇒ 36 + 12 x = 3 x

⇒ x = - 4 hours

This is the time required by Machine B to create a widget.
