Lelu [443]

Answer:

840 cubic inches

Step-by-step explanation:

Given:

The wooden steps have two parts.

Both of which are rectangular prisms.

The top part is 6 inches tall, 5 inches wide and 10 inches long.

The bottom part is 6 inches tall, 9 inches wide and 10 inches long.

Question asked:

What is the volume of the steps?

Solution:

<u>For top part</u>

Length = 10 inches

Width = 5 inches

Height = 6 inches

<u><em>As we know:</em></u>

<u><em /></u> $Volume\ of\ rectangular\ prism =length\times width\times height$

$=10\times5\times6=300\ cubic\ inches$

<u>For bottom part</u>

Length = 10 inches

Width = 9 inches

Height = 6 inches

Similarly

$Volume\ of\ rectangular\ prism =length\times width\times height$

$=10\times9\times6=540\ cubic\ inches$

Volume of two steps = 300 + 540 = 840 cubic inches

<em>Therefore, the volume of the steps are 840 cubic inches.</em>

The sun shines at a 60∘ angle to the ground. A flagpole is 20 feet tall. If you are trying to find the length of the shadow cast

almond37 [142]

Answer: From the 60° angle, the flagpole is the opposite side and the shadow is the adjacent side of the triangle.

tangent 60° = opposite/adjacent

so

tan 60° = 20/x

multiply both sides by x and you have

x · tan60° = 20

divide both sides by tan 60° and you have

x = 20/tan60°

x = 11.5 ft.

if this is wrong sorry don’t be mad but if it’s right then hope this helps

Which is irrational?

sladkih [1.3K]

Answer:

The square root of an integer is rational if the integer is a perfect square. You probably know the first few perfect square integers are 1, 4, 9, 16, 25, 36, ...

The integer 5 is not on that list, so its square root will be irrational.
