16(4) = 64. 7(3) = 21
64/21 simplifies to 3 and 1/21 as 21 goes into 64 three times. Option C is your answer.

Determine the coordinates of C
To do this, we make use of:

So:
Answer: $210.75
Explanation: You multiply the price of the object by how many they buy.
So for the beams you calculate 3 x 45.25 and get 135.75. For the screws you multiply 6 x 12.50 and that equals 75. Then, for the total price you add the two together, so 135.75 + 75 = 210.75
Another way to do it is (3 x 45.25) + (6 x 12.50) = 210.75
Answer:
NO
Step-by-step explanation:
Surface area = 2lw+ 2 lh + 2 hw Where h = height, w= width and l = length
We will double w
SA becomes 2l(2w) + 2lh + 2h(2w)
SA = 4lw + 2lh + 4lw
Doubling the SA
2SA = 2(2lw+ 2 lh + 2 hw)
= 4lw + 4lh +4 hw
2SA =? SA for 2w
4lw + 4lh +4 hw = 4lw + 2lh + 4lw
This is not the same
Doubling one dimension does not double the surface area
Angle T and Angle R are vertical angles, which means they are congruent (equal in measurement)
Use substitution to go from
Angle T = Angle R
to
3x+36 = 6x-9
Now let's solve for x
3x+36 = 6x-9
3x+36-3x = 6x-9-3x
36 = 3x-9
36+9 = 3x-9+9
45 = 3x
3x = 45
3x/3 = 45/3
x = 15
Since x = 15, we can say,
Angle T = 3x+36
Angle T = 3*x+36
Angle T = 3*15+36 ... x is replaced with 15 (since x = 15; found above)
Angle T = 45+36
Angle T = 81
The final answer is 81 degrees
