Answer:
=1232cm^3
Step-by-step explanation:
Volume of a cylinder=πr^2h
Where r=radius=diameter/2=14/2=7 cm
h=height=8 cm given
π=22/7
Volume of cylinder=πr^2h
=22/7x7x7x8=154x8=1232cm^3
Let say
e=number of english teachers
m=number of math teachers
3 more english tahn math
e=m+3
ratio if e to m is 6:5
e:m=6:5
e/m=6/5
e=m+3
(m+3)/m=6/5
times 5m both sides
5(m+3)=6m
5m+15=6m
minus 5m both sides
15=m
e=m+3
e=15+3
e=18

Answer:
(C) Since 1/2 and 3/4 are both either equal to or greater than 1/2, the total must be equal or greater than 1. So, 4/6 is not a reasonable answer, as 4/6 is less than 1.

Answer:
The distance from the house to the school is 500 units
Step-by-step explanation:
The distance we want to calculate represents the hypotenuse of the right triangle
So, to use the Pythagoras’ theorem, we need the two other side lengths apart from the hypotenuse
The base side measures (350-50 = 300 units)
The measure of the height is (450-50 = 400 units)
Mathematically, the theorem states that the square of the hypotenuse equals the sum of the squares of the two other sides
Thus, we have it that;
h^2 = 300^2 + 400^2
h^2 = 90,000 + 160,000
h^2 = 250,000
h = √250,000
h = 500 units
