aliina [53]

Area is calculated by taking the length times the width.
A=lxw

one shed is 9 x 4 =36 square feet.
the other shed will be the same but have a four sides equal.
a shed with side of 6 x 6 will have a area of 36 square feet.

one side of the square shed would be 6 feet.

Answer:

Step-by-step explanation:

using the rule of radicals

• $\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

simplifying $\sqrt{32}$

$\sqrt{32}$ = $\sqrt{16(2)}$ = $\sqrt{16}$ × $\sqrt{2}$ = 4 $\sqrt{2}$

$\sqrt{32}$ + 5 $\sqrt{2}$

= 4 $\sqrt{2}$ + 5 $\sqrt{2}$ = 9 $\sqrt{2}$ → D

Yanka [14]

Answer:

11.29.

Step-by-step explanation:

We are given that The mean length of six-year-old rainbow trout in the Arolik River in Alaska is 478 millimeters with a standard deviation of 38 millimeters.

We are also given that these lengths are normally distributed.

So, The highest value is at mean .(Refer the attached figure).

Formula : $Percentile = \frac{Length}{Maximum} \times 100$

$54 = \frac{Length}{478} \times 100$

$\frac{5400}{478} =Length$

$11.297 =Length$

The 54th percentile of the lengths is 11.29.
