Answer:
x = 87
Step-by-step explanation:
37 + 56 = 93
triangles always equal to 180
180 - 93 = 87
Answer: Total Volume = 15π + 18 π= 33π cubic mm
Step-by-step explanation:
What is the volume of the composite figure? Leave the answer in terms of π.
_33π mm3
We have a cone here conjoined to a semi-sphere.
so
Cone volume: C = (1/3)*(πr^2) * h
semi-sphere volume : V = (1/2)* (4/3) * (π * r^3)
r = 3 mm and h = 5mm
so C = (1/3)*(π (3)^2) * 5 = 15π cubic mm
V = (1/2)* (4/3) * (π * 3^3) = 18 π cubic mm
Total Volume = 15π + 18 π= 33π cubic mm
Answer:
52
Step-by-step explanation:
140 - 13 = 127
127 - 75 = 52
Check your work:
75 + 13 + 52
= 140
Answer:
Imani's rent had a higher percent increase
Step-by-step explanation:
A change from 560 to 600 represents a positive change (increase) of 7.1428571429%
A change from 825 to 875 represents a positive change (increase) of 6.0606060606%
Percent change = New - Old /825 × 100
Answer:
200
Step-by-step explanation:
25 percent is known to be 1/4 of a number, so if 50 teachers represent 1/4 of all the teachers, that means that in order to get a full number, we must multiple 50 by 4 in order to get all 100% of the teachers.
By doing 50x4, we can conclude that 200 teachers teach at the school (aka 100% of all teachers)
