How would I figure out what L= is if V=168 yd W= 7 yd H= 3 yd?

Mariulka [41]

We can assume that the shape is a rectangular prism by the given dimensions

Volume of a rectangular prism
Volume = Area of Base × Height of prism
= Length × Width × Height of prism
Substitute!
168 = L × 7 × 3
168 = L × 21
Divide 21 on either sides to isolate L

$\frac{168}{21}$ = $\frac{L*21}{21}$
21 and 21 cancels out

8 = L
L = 8 yd

A rose garden is formed by joining a rectangle and a semicircle, as shown below. The rectangle is 24 ft long and 14 ft wide.

expeople1 [14]

rounded part is a semicircle so the area for that is the area of a circle ÷ 2

area of the rectangle + (area of the circle ÷ 2) = answer

24 * 14 = 336 = area of the rectangle

14 ÷ 2 = r

(pi * 7^2) ÷ 2

(pi * 49) ÷ 2 = 153.86 ÷ 2 = 76.93 = area of semicircle

336 + 76.93 = 412.93 ft^2 = answer

Last week Missy read for a total of 240 minutes during this time she read 112 pages at this rate how many pages did she read in

LuckyWell [14K]

Answer:

28 pages

Step-by-step explanation:

240 minutes = 4 hours

240 minutes = 112 pages read

You have to divide by 4 the numbers are in each side, it would be like this:

60 minutes = 28 pages read

60 minutes is equal to an hour

1 hour = 28 pages read
