Hello!
I believe the answer is 58°.
Explanation: In order to find this answer, we must first add up the two numbers; 87+35. After adding, your solution should be 122. In order to be a triangle, all of the degrees must all add up to 180°. Next we must subtract 122 from 180. After subtracting, the answer is 58. Therefor your answer is 58°.
Answer:
I think maybe E. I never really solved a question like this before but to find the mean you add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
Step-by-step explanation:
Just multiply the number out of the parentheses with the ones inside. So -8 times 9=-72 and 3q times -8=-24q. Now keep the same operation, which is subtraction in this case.So, -72--24q or -72+24q will be the correct answer.
To find the decimal equivalent for 2/3, you simply divide 2 by 3.
After dividing, the decimal equivalent will be about 0.6666666667
The volume of a rectangular box is equal to the area of its base times the vertical height. Thus,
V = Ah = 80
Since the base is a square with side x, then the area is equal to x². Hence, we can express h in terms of x.
80 = x²h
h = 80/x²
Now, each lateral side of the rectangular box is in the shape of a rectangle with a length of h and a width of w. Hence, the equation for the total cost would be:
Total Cost = Cost per area of lower base + Cost per area of upper base + 4(Cost per area of lateral side)
Total Cost = 0.45x² + 0.28x² + 4(0.10h*x)
Total Cost = 0.73x² + 0.4hx
Since h = 80/x²,
Total Cost = 0.73x² + 0.4(80/x²)(x)
Total Cost ($) = 0.73x² +32/x
