The escalator at Northpark Mall of Jackson rises 36
feet over a horizontal distance of 64 feet. What is its
slope?
Answers
Using the slope concept, it is found that the slope is of 56.25%.
--------------------------
Slope is normally represented as a percentage, representing rate of change, and it is given by:
[tex]S = 100{V}{H}[/tex]
In which:
V is the vertical distance.H is the horizontal distance.--------------------------
The escalator rises 36 feet, thus the vertical distance is [tex]V = 36[/tex]The horizontal distance is [tex]H = 64[/tex]Thus, the slope, as a percentage is:
[tex]S = 100{V}{H} = 100 \times \frac{36}{64} = 56.25[/tex]

Are points Q, R, X, & W non-coplanar? Explain.
Answers
Answer:
No, they are co-planar.
Step-by-step explanation:
Points Q, R, X, and W are all in the plane QRXW. Planes do not have to be at ninety-degree angles (that is, straight up and down or straight to the left and right). However, the points Q, S, U, and X would not be coplanar as a plane must be a flat surface.

A foundational background concept is that multiplying by 10 makes a number bigger and moves the decimal to the right.
For example: 3.4 x 10 = 34
The counterpart for that is that dividing by 10 makes a number smaller and moves the decimal to the left.
For example: 3.4 ÷ 10 = 0.34
So, when you see 3.4 x 10^5, this means you’re multiplying by 10 fives times, so that will move the decimal point five places to the right.
3.4 x 10^5 = 340 000
On the other hand, when you see a negative exponent on the 10, then that means you’re actually dividing by that many 10s and will move the decimal point that many places to the left. (to make the number smaller)
3.4 x 10^-5 = 0.000034
So, you need to first identify if you’ll make the number bigger or smaller and then how many places the decimal point will need to move.

Answer:
The GCF is going to be 20
Step-by-step explanation:
This Is how I find the GCF of 2 numbers. I find the prime factorization first, then I find the common factors and multiply them. Here
The prime factorization of 20, 2 × 2 × 5= 20
The prime factorization of 80, 2 × 2 × 2 × 2 × 5 = 80
The common factors are 2, 2, and 5. We multiply those to get the GCF.
2 × 2 × 5 = 20

The square below represents one whole.What percent is represented by the shaded area?
Answers
You won't type in the percent sign as that's already taken care of
=============================================================
Explanation:
We have 6 squares shaded out of 100 total. This means we have 6/100 = 0.06 = 6% of the squares shaded. The term "percent" means "per 100" or "for every 100".
Take note that there are 10 rows and 10 columns, meaning there are 10*10 = 100 squares total, either shaded or not shaded.

Answer:
[tex]\frac{5-\sqrt{2}}{27}[/tex]
Step-by-step explanation:
This kind of problem uses a sort of algebra trick.
To rationalize [tex]\frac{1}{5+\sqrt{2}}[/tex], multiply both numerator and denominator by what is called the conjugate radical -- the same expression but with opposite sign.
Note: this is really a clever name for 1, and multiplying by 1 does not change the value of an expression, it changes the way the expression looks.
Here goes:
[tex]\frac{1}{5+\sqrt{2}} \cdot \frac{5-\sqrt{2}}{5-\sqrt{2}}=\frac{5-\sqrt{2}}{25+5\sqrt{2}-5\sqrt{2}+2}\\=\frac{5-\sqrt{2}}{25+2}\\=\frac{5-\sqrt{2}}{27}[/tex]

So basically if each square is equivalent to one square foot, and 1 paint can covers 6 square feet, then you basically count out how many squares there are and divide by six. So 20 square feet (all of the dark squares added) divided by 6 (how many square feet the paint covers). So 6 goes into 20, 3 times, with 2 left over. So you’ll need about 2 cans and somewhere around 80% of the third one. Or something along those lines if you want to get exact. But really it’s 3 cans (there is just a little left over).
