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.
Answer:
56.549 cm (choice 1)
Step-by-step explanation:
If the area of the square if 36 cm, then each side is 6 cm.
That means the diameter for each semi circle is also 6 cm.
Formula for a semi circle is 1/2(πr²)
We need the radius, which is half the diameter. So the radius is 6÷2= 3
Now plug in to the formula.
A= 1/2(π3²)
A= 14.137 (nearest hundredths)
Now multiply that by 4, because there are 4 semi circles
4(14.137)= 56.549 cm (nearest hundredths)
Answer:
A - 4? (Don’t quote me)
Explanation:
It says the tank needs to be quadrupled, and quadrupled means by 4.
