Sample response: <span>Yes, the fan will provide enough airflow. The volume of the ranger station is 720 cubic feet. The ranger station requires a 720 CFM fan. 1,500 CFM is greater than 720 CFM, so it will be enough airflow.</span>
Answer:
Step-by-step explanation:
Since there are missing data, let's discuss some facts about regular polygons and their angles.
1) The sum of its Interior angles is given by:

2) Since it is a regular pentagon, each interior angle is congruent:
Each interior angle:

3) If we trace an outside line, the external angle will be supplemental, i.e.

4) If we trace from each diagonal one line segment, in a regular pentagon that will form 3 triangles with one-third of 108º,i.e.,36º
As we can see, the in the picture below
We have two ways to solve this question
1)sin45=4√2 /x
√2 /2 =4√2 /x
X=8
2)Pythagorean theorem
In a 45-45-90 degree triangle
(4√2)^2+(4√2)^2=x^2
X=8
7x +2y +4 is the simplified form of this expression.
Answer:
<h2>The number is 75</h2>
Step-by-step explanation:
Let the number be x
A third of a number is written as

A third of a number minus 8 is written as

The result is 17
We have

<u>Add 8 to both sides of the equation</u>
That's

<u>Multiply through by 3 to eliminate the fraction</u>
That's

<h3>The number is 75</h3>
