Answer: 376.8m
Step-by-step explanation:
Total surface area of a cylinder is calculated by 2πrh+2πr2, where π is a constant, given as 3.14, h is the height= 7m and r is radius= 5m
rh = 5m x 7m = 35m while
r^2 = 5m x 5m = 25m
Slot the values into the formula:
V = 2 x 3.14 ( 35) + 2 x 3.14 (25)
V= (6.28 x 35) + (6.28 x 25)
= 219.8 + 157
V= 376.8m
I hope this helps.
the answer is 10 hoped this helped have a great day
Answer:
The pet sitter babysat his dog for 3 hours.
Step-by-step explanation:
You know that a pet sitter charges $ 20 for supplies and $ 10 per hour of service, represented by the equation C = 10*n + 20, which describes the total cost she would charge for n hours of service.
The pet sitter charges a customer $ 50 for his service, so C has a value of $ 50.
Replacing:
50=10*n+20
Solving:
50 - 20= 10*n +20 -20
30= 10*n
30÷10= n
3= n

Hi there! :)
Answer:
y = -2x + 3
Step-by-step explanation:
We can write an equation in slope-intercept form. Use the slope formula to find the rate of change in the table:
Plug in values from the table:
Simplify:
m = -2 (rate of change)
Use a point from the table (-2, 7) and the slope to solve for the equation for the linear function:
7 = -2(-2) + b
7 = 4 + b
7 -4 = b
b = 3
Rewrite:
y = -2x + 3 is the equation for the linear function.
X=60
That’s the answer
What I did to get it
(3x-60)=120
+60. +60
3x =180
————. = 60
3
X=60
