would you classify the number 200 as a perfect square, a perfect cube,both, or neither? explain
Answers
A: No, the number 200 is not a perfect square.
B: No, the number 200 is not a perfect cube.
C: Yes. the number 200 is neither.
No number times itself twice or threefold is 200 therefore I can conclude it's neither.
Answer: neither because a perfect square is number like 9 or 100 where 3^2=9 and 10^2=100 and likewise for a perfect cube. 200 is not a perfect square or perfect cube for any number

How can you use unit rates to solve pricing problems?
Answers
Answer:
a ratio is a comparison of two numbers or measurements
the objects being compared are called the terms of the ratio.
if the tow terms are different units this is called a rate.
example:
David covers 600 miles in 8 hours and John covers 380 miles in 5 hours. Who is driving faster ?
solution:
Distance covered by David in 1 hour is
= 600 / 8
= 75 miles per hour
Distance covered by John in 1 hour is
= 380 / 5
= 76 miles per hour
When we compare the above unit rates (Distance covered in 1 hour), John is driving faster than David.
We can use unit rates to solve pricing problems because we solve for price of one of that item.
For example, David bought 5 pounds of peanuts for $10, how much does it cost for one pound?
10 / 5 = $2 per pound
The $2 is the unit rate and we use to find if David buys more then 10 pounds.

15. If gasoline costs $4.02 per gallon, your tank holds 13 gallons, and your car averages 26 miles per gallon,
a) If your tank is full, how far can you drive before you run out of gas?
b) If your tank were empty, how much will it cost to fill up your tank?
Answers
Answer: a) 338 miles
b) $52.26
Step-by-step explanation: To get the amount of miles that your car can drive before running out of gas, you just multiply how many gallons you have by how many miles each gallon lasts. Then, to get the cost of all the gas, you multiply the cost of the gas by how many gallons you need.

Which of the following is the solution set of the given equation?
(x - 3) - 2(x + 6) = -5
A) {-10}
B) {-4}
C) {8}
Answers
first you distribute the -2 throughout (x+6) which then becomes, -2x -12
After you’ve done that plug it in the equation, the equation should be, x-3-2x-12=-5
Now combine like terms. After it should look like, -x - 15 = -5, Add 15 to both side. It should be, -x = 10
Finally divide by -1 on both sides and that should give you x= -10

If (–6, y) is a solution to the equation –7x − 5y = –68, find the value of y.
Answers
Steps to solve:
-7x - 5y = -68 when x = -6
~Substitute and simplify
-7(-6) - 5y = -68
42 - 5y = -68
~Subtract 42 to both sides
-5y = -110
~Divide -5 to both sides
y = 22

y = -1/2x - 3
In this form, we see that the slopes of the two lines are -1/2 and 2, so the product of their slopes is -1. That means the lines are perpendicular.
