What is the volume of a rectangular prism with a length of 8 1 /2 812 cm, width of 9 1/3 913 cm and a height of 12 2/5 1225 c

blondinia [14]

The volume of a rectangular prism is obtained by multiplying the length, width and the height of the prism. You can multiply them in any order to get the same different result. We calculate as follows:

V = lwh
V = 8 1 /2 (9 1 /3) (12 2/5)
V = 983.73

Hope this answers the question. Have a nice day.

Mary jogged from Point P to Point Q while Wyatt jogged from Point Q to Point P.

12345 [234]

Answer:

When did Mary and Wyatt meet? 0.5 minutes later

How far from point Q did they meet? 3.5 km

Step-by-step explanation:

Mary’s motion is represented by d = 8t----(1)

Wyatt’s motion is represented by 2d + 14t = 15----(2)

We solve for d in equation (2) to get:d=7.5-7t----(3)

We equate equation (1) and (3) to get:

$8t=7.5-7t$

We now solve for t to get:

$8t+7t=7.5$ $15t=7.5$

$t=\frac{7.5}{15}=0.5$

Now put t=0.5 into equation (1) to get d=0.5*8=4

This means they met 4 km from point P.

Therefore they meet 7.5-4=3.5km from point Q
