Answer:
The customer pay to the plumber be $148 .
Step-by-step explanation:
As given
A plumber uses the expression 48 + 25h to determine the number of dollars to charge each customer.
If h = 4
Customer pay to the plumber = 48 + 25 × 4
= 48 + 100
= $148
Therefore the customer pay to the plumber be $148 .
Answer:
x = 6 cm
Step-by-step explanation:
Given ratio of sides of similar figures = a : b , then
ratio of areas = a² : b²
Here ratio of areas = 5 : 45 = 1 : 9 , so
ratio of sides =
:
= 1 : 3
Thus side of B is 3 times side of A
x = 3 × 2 = 6 cm
1. Observe problem
Solve for the area and Circumference of a circle who's radius is 3 cm
Area for circle formula:
pi*r^2=
9pi
I simplicity is needed, 9 pi is around
28.2743338823cm^2
Circumference for circle formula: 2*pi*r
which is
6pi
if simplicity is again needed, its around
18.8495559215cm
Answer:
The true statements are (D) and (E). This is a square with sides equal to 5 units so that means that its perimeter is 4×(5 units) or 20 units and its area is (5 units)×(5 units) or 25 units^2.
1. 12-9×3×4+3=-93
2.3+4×3×9-12=99
3. 12-9+3×9×3×4=327
