Answer:
It is the first one
Step-by-step explanation:
Hi, it is the first one because there is 4 - 1/2 3 - 3/4 and 2 - 1/4
The graphs of two linear equations cannot intersect in two different points. the correct answer is B.
Answer:
The volume of the cylinder with given height and radius is 150.72 centimeters³ .
Step-by-step explanation:
Given as :
the height of cylinder = H = 12 centimeters
The diameter of cylinder = D = 4 centimeters
So The radius of cylinder = R = 
Or, R =
I.e R = 2 cm
The volume of cylinder is given as V =
×R²×H
where R is the radius and H is the height
So, V = 3.14×(2)²×12
Or, V = 3.14×48
∴ V = 150.72 centimeters³
So, The volume is 150.72 centimeters³
Hence The volume of the cylinder with given height and radius is 150.72 centimeters³ . Answer
Answer:
6610
Step-by-step explanation:
Move the decimal 2 spots to the right and add 2 zeros more behind the 528.8
so its becomes 8 divide what that number is
Answer:

Step-by-step explanation:
Let's set up a system of equations. (1 equation for yesterday and 1 for today).
- Let h = haircut and c= color
(Yesterday: 2 haircuts and 1 color for $194).
(Today: 2 haircuts and 4 colors for $494).
Notice that both equations have a 2h. If we subtract the two equations, the 2h will cancel and leave us with one variable, c.



Since we are solving for c, we must isolate the variable. It is being multiplied by -3. The inverse of multiplication is division. Divide both sides by -3.

Now we have to solve for h. Plug 100 in for c in the first equation.

100 is being added, so we must subtract 100 from both sides.

h is being multiplied by 2, so we divide both sides by 2.

A haircut costs $47 and a color costs $100.
