Answer:
19
Step-by-step explanation:
This was done the normal way of multiplying and dividing first:
If p=1 and q=4, evaluate the following expression:
4q − p/p + q = ?
4(4) - 1/1 + 4 = 16 - 1 + 4 = 19
If you wanted to do the addition and subtraction first, the equation would have been:
(4q - p)/(p + q) = ?
(4(4) - 1)/(1 + 4) = 15/5 = 3
With the parentheses, the order of operations is done in the parentheses first.
Supplementary angles add to 180 so x + 128.7 = 180 subtract 128.7 from both sides; therefore, the answer is 51.3
I hope this helps!

Perimeter is 12 units
Answer:
151 in^3
Step-by-step explanation:
The rocket consists of two shapes - a cone and a cylinder
the volume of the plastic = volume of cone + volume of cylinder
volume of a cylinder = nr^2h
Volume of a cone 1/3(nr^2h)
n = 22/7
r = radius
the diameter is the straight line that passes through the center of a circle and touches the two edges of the circle.
A radius is half of the diameter
Radius = 5/2 = 2.5
Height of cone = 11 - 6 = 5
Volume of plastic = (22/7) x (2/5^2) x 6 + (1/3) x (22/7) x (2/5^2) x 5 = 117.9 + 32.7 = 150.6 in^3 = 151
