Answer:
So, the area of a trapezoid is A=9h in square feet.
Step-by-step explanation:
We know that a h represent the height in feet. We have that the base lengths of 7 feet and 11 feet. So,
We calculate the area in square feet, where A represent the area.
We have the formula for the area of a trapezoid:
Therefore, we get:
So, the area of a trapezoid is A=9h in square feet.
Answer: The volume of the cylinder is 9,184.5 cubic millimeters.
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a cylinder (V) : π x radius ² x height
Replacing with the values given and solving for v (Volume)
V = 3.14 x 15² x 13
V = 9,184.5 mm3
In conclusion, the volume of the cylinder is 9,184.5 cubic millimeters.

It asks to "Find the unit price in dollars per padlock"
The phrasing "dollars per padlock" is the same as "dollars per 1 padlock"
In other words, the teacher wants to know how much 1 padlock costs.
7 padlocks : $23.80
7/7 padlocks : $23.80/7 .... divide both parts by 7
1 padlock : $3.40
We see that 1 padlock costs $3.40, so the unit cost is $3.40 per padlock
Answer:
$160
Step-by-step explanation:
Simple interest=principal×time×rate/100
Principal=$800
Time=5years
Rate=4%
S.I=800×5×4/100
S.I=8×4×5
S.I=160
So the simple interest is $160
<em>The first one would be the Commutative property of multiplication because you are just flipping a multiplication equation.</em>
<em>The second one would be Commutative property of addition because you are still just flipping it but, it is an addition equation.</em>
