Answer: 57%
Step-by-step explanation:
Davis's monthly expenditure and his monthly salary was 3 : 7.
This means that for every $7 he received, he spent $3 out of it.
The amount he saved is therefore:
= 7 - 3
= $4
For every $7 received, he saved $4.
Percent = 4/7
= 57%
(2,1) and (3,6)
Slope = (6-1)/(3-2) = 5
y = mx + c
y = 5x + c
at point (2,1)
1 = 5(2) + c
1 = 10 + c
c = -9
y = 5x - 9
Answer:
f(- 3) = 12
Step-by-step explanation:
Substitute x = - 3 into f(x) , that is
f(- 3) = (- 3)² - (- 3) = 9 + 3 = 12
Answer:
3
Step-by-step explanation:
Volume if a cone is given by the formula
V=⅓πr²h
Where V is the volume, r is radius and h is height.
Given diameter as 3 m, the radius will be half of this hence 3/2=1.5 m
Substituting 4m for h and 1.5 m for r then
V=⅓π×1.5²×4=3π m³
Therefore, the missing figure is 3
