Answer:
x= 113
y= 67
z= 49
Step-by-step explanation:
a triangle equals to 180° so lets start with the triangle that has two given degrees
28 + 39 + x = 180 solve
x = 113
no we can find y by using x + y = 180 since it's a straight line
we know the value of x so 113 + y = 180. solve.
y= 67
now do the same thing we did from the start since we have two given degrees on the other triangle.
67 + 64 + z = 180
z= 49
Answer:
50.3 cm³
Step-by-step explanation:
Use the cylinder volume formula:
V = 
r²h, where r is the radius and h is the height.
Since the radius is half of the diameter, and the cylinder has a diameter of 4 cm, this means the radius is 2 cm.
Plug in the radius and height into the equation:
V = r²h
V = (2²)(4)
V = 16
V = 50.3 cm³
-31/15 is the correct answer
Step-by-step explanation:
the mean value is the sum of all values divided by how many values there are.
so,
(3 + -5 + 70 + -90 + -13) / 5 = -35/5 = -7
-7° F is the mean temperature of the 5 cities.
