Answer:
Step-by-step explanation:
<u>We know that:</u>
- Side lengths of rectangular prism: 2 in, 5 in, and 6 in.
- Surface area = Area of all faces
<u>Solution:</u>
- Surface area = 2(6 x 2) + 2(5 x 2) + 2(6 x 5)
- => Surface area = 2(12) + 2(10) + 2(30)
- => Surface area = 24 + 20 + 60
- => Surface area = 104 in.
Hence, the surface area of the rectangular prism is 104 in.
Answer:
D
Step-by-step explanation:
Using the tangent ratio in the right triangle
tanθ =
=
, then
θ =
(
) ≈ 60° ( to the nearest degree )
Answer:
A form of blocking by three variables.
Step-by-step explanation:
Graeco-Latin square design is a special type of comparative design.
Graeco-Latin square design uses 3 blocking variables unlike the 2 blocking variable as used by the standard Latin square design.
In this square design of experiment, the experimental units are grouped into three different ways.
$22.50. change 25% into decimal. 0.25 and multiply the original price by percent in decimal form you will get the amount that is taken off so subtract that from original:)
Answer:
D
Step-by-step explanation:
First, let's find <em>x</em>.
We know that one of the angles is 30. The side opposite to than angle is 11, and <em>x</em> is the adjacent side to it. Therefore, we can use the trig function tangent.
Recall that:

Plug in 30 for the angle, 11 for the opposite, and <em>x</em> for the adjacent. Solve for <em>x</em> by cross-multiplying:

From the unit circle, recall that tan(30) is equal to one over the square root of 3. Thus:

Now, we can use the Pythagorean Theorem to find <em>y</em>. <em>y</em> is the hypotenuse. Thus:
