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

The square below represents one whole.

sergij07 [2.7K]

Answer:

Decimal: 0.23

Fraction: 23/100

Percent: 23%

Step-by-step explanation:

In this case, one whole is 100. This is because there are 100 little squares in the one big square.

The amount of shaded squares is 23.

This can be represented as the fraction 23/100. 23/100 is the same as 23 being divided by 100. 23 divided by 100 is 0.23 (our decimal). To find a percent, move the decimal point to the right 2 times. Our percent is 23%.

Solve for x. Round to the nearest tenth.

Nana76 [90]

Answer:

x = 103.5

Step-by-step explanation:

tan 12 = 22/x

Multiply each side by x

x * tan 12 = 22/ x*x

x tan 12 = 22

Divide each side by tan 12

x tan 12 / tan 12 = 22/ tan 12

x = 22 / tan 12

x = 103.5018624

Rounding to the nearest tenth

x = 103.5
