Answer:
88 ft^2
Step-by-step explanation:
For a rectangular prism with dimensions 1 ft by 8 ft by 4 ft, there are two opposite faces with dimensions
<em>1 ft by 8 ft, </em>
two opposite faces with dimensions
<em>1 ft by 4 ft, </em>
and two opposite faces with dimensions
<em>4 ft by 8 ft.</em>
We find their area and add them.
SA = 2 * 1 ft * 8 ft + 2 * 1 ft * 4 ft + 2 * 4 ft * 8 ft
SA = 16 ft^2 + 8 ft^2 + 64 ft^2
SA = 88 ft^2
For this case we have the following expression:

We must indicate an equivalent verbal expression.
If "p" is a variable that represents any number, we can write:
Four times a number plus 3 equals -5.
Answer:
Four times a number plus 3 equals -5.
Option D
Well the angle is acute at the 3 it would be a right angle so I'm guessing it's 30 degrees but if I'm wrong u could use a protractor to find the angle of degrees
Answer:

Step-by-step explanation:
Given: 76,45,64,80,92
Required: Determine the standard deviation
We start by calculating the mean

Where x-> 76,45,64,80,92 and n = 5



Subtract Mean (71.4) from each of the given data

Determine the absolute value of the above result

Square Individual Result

Calculate the mean of the above result to give the variance


Hence, Variance = 255.298
Standard Deviation is calculated by
