$6.4
so, if he gets 40% of a thing, that means he gets a reduced price.
to conduct sales tax, we need to move the decimal places 2 places to the left of the percent, so 40% becomes .40
then, multiply it to 8.50
that equals 3.4
3.4 is how much is taken away from him.
so, we subtract 3.4 from 8.50
that is 5.1. thats how much he gets from this haircut, but he gets a 1.30 tip
add 1.30 to 5.1
we get $6.4. thats how much he gets.
None of those are outliers because they are all within .1 of each other.
Answer:
The solution to a system of linear equations represent the place where the lines intersect. P.S. If the lines are parallel, they will never intersect and there is NO solution. If the lines are coincident (same line) there are infinitely many points of intersection so there are MANY solutions. If the lines cross, then there is ONE solution.
Step-by-step explanation:
None of the above. make sure you have it said the right way
The quarter circle pieces are all congruent allowing us to glue them together to form a circle. The circle will be completely inside the square. This circle is as large as possible so it's not spilling outside of the square.
The area of the square is 8*8 = 64 square units
The circle has a radius of 8/2 = 4 units. Use r = 4 and plug this into the area of a circle formula
A = pi*r^2
A = pi*4^2
A = pi*16
A = 16pi
Now subtract the two areas
(area of square) - (area of circle) = 64 - 16pi
The exact answer, in terms of pi, is 64 - 16pi
If your teacher wants you to find the approximate decimal version, then you would use a calculator to find that 64 - 16pi = 13.7345175 approximately. If you end up going with the approximate answer, be sure to follow the instructions on what your teacher wants with rounding.
