Answer:
210 cm³
Step-by-step explanation:
The area of the triangular side is base*half height, which is 7*3=21.
To get the volume, multiply by the depth: 21*10 = 210 cm³
Answer:
Rounded, 22 yards.
Step-by-step explanation:
The pythagorean theorem states: a^2 + b^2 = c^2
a = 34, squared = 1156
b = 41, squared = 1681
Add those to get 2837.
√2837 = 53.26, rounded.
34 + 41 = 75
75 - 53 = 22
22 yards is your answer.
For this case we have the following inequality:

Subtracting 4 from both sides of the inequality we have:

Dividing between 7 on both sides of the inequality we have:

Thus, the properties used were:
Subtraction property
Division property
Answer:
Subtraction property
Division property
Answer:
Choice A.
Step-by-step explanation:
Apply the vertical line test.
If a vertical line intersects 2 or more points on the graph, the relation is not a function.
If all vertical lines intersect at most 1 point on the graph, the relation is a function.
Any vertical line in Choice A. intersects 1 single point. Choice A. is a function.
There are vertical lines that would intersect 2 points of the graph in Choices B., C., and D., so they are not functions.
We have a work problem here. We can use our knowledge on ratio and proportion in order to set up and equation to determine what is being asked. We do as follows:
1 job / 3 hours for both = 1 job / 8 hours for charlie + 1 / x hours for sam alone
Therefore, the equation would be
1/3 = 1/8 + 1/x
