Answer: The real answer is 19/10 or 1 and 9/10

Step-by-step explanation:

Jackie added 1/2 and 1/4 to get 1/8 but in order of operation you have to multiply and divide first . So she should have divided 1/2 by 1/4 and then added that with -1/10 .

A 12 gallon tank is filled with water at a rate of 1/4in 5 seconds. It will take ____ Minutes and ____ seconds to fill 5/6 of th
vlabodo [156]
If a 12 gallon tank is filled with water at rate of 1/4 of the tank in 5 seconds, then it's filled with 3 gallons per 5 seconds (because 1/4 * 12 = 3). 5/6 of the tank is as much as 5/6 * 12 = 5 = 60/6 = 10 gallons.

If 3 gallons of the tank are filled in 5 seconds, then 10 gallons will be filled in (10 ÷ 3) * 5 = 3 1/3 * 5 = 16 2/3 seconds.

Answer: It will take 0 minutes and 16 2/3 seconds to fill 5/6 of the tank.

I hope that's what you meant :)

Erica walked down a trail into a valley.
inysia [295]

Answer:

Erica's vertical distance from the top of the valley (in kilometers) after walking 2 kilometers along the trail is T.

Step-by-step explanation:

It is given that V(d) models Erica's vertical distance from the top of the valley (in kilometers) after walking d kilometers along the trail.

We need to find the meaning of V(2)=T.

On comparing V(d) and V(2), we get d=2.

Since V(d) models Erica's vertical distance from the top of the valley (in kilometers) after walking d kilometers along the trail, therefore V(2) models Erica's vertical distance from the top of the valley (in kilometers) after walking 2 kilometers along the trail.

V(2)=T

It means Erica's vertical distance from the top of the valley (in kilometers) after walking 2 kilometers along the trail is T.
