Answer:
x-4
Step-by-step explanation:
|x−4| if x>4
That means x-4 is always positive since x> 4
x-4
The surface area of a cylinder is:
A=2pr^2+2prh and since r=d/2
A=2p(d^2/4+dh/2)
A=(p/2)(d^2+2dh) and we need 200 of these cylinders...
A=(100p)(d^2+2dh), and using d and h, 3.5cm and 70cm we get:
A=(100p)(3.5^2+2*3.5*7)
A=(100p)(12.25+49)
A=6125p cm^2
A≈19242 cm^2 (to nearest cm^2)
Answer: 2
Step-by-step explanation:
Answer:
4 hours to pay the same amount
and aif you want a 3 hours work you should get carpenter A
Step-by-step explanation:

carpenter A for 3 hours:

carpenter B for 3 hours:

Horizontal line is y=a, where a is a constant (number).
We need to choose equation this type.
y= - 7, means that for all values of x y=7.
So, answer is
B. y= - 7
