Answer:
[tex]Perimeter = 4x+16[/tex]
Step-by-step explanation:
Given
[tex]Rug=x[/tex]
Required
Determine the perimeter of the room
The room is 3ft wider.
So:
[tex]Width = Rug + 3[/tex]
[tex]Width = x + 3[/tex]
The room is 5ft longer,
So:
[tex]Length = Rug + 5[/tex]
[tex]Length = x + 5[/tex]
The perimeter is:
[tex]Perimeter = 2 * (Length + Width)[/tex]
[tex]Perimeter = 2 * (x+5+x+3)[/tex]
Collect Like Terms
[tex]Perimeter = 2 * (x+x+5+3)[/tex]
[tex]Perimeter = 2 * (2x+8)[/tex]
[tex]Perimeter = 4x+16[/tex]

Juan plans to build a ramp from his window to the sidewalk so he can skateboard right out his window on his way to school. His window is 5ft off the ground and the sidewalk is 12ft from his house.
Given :
Height of the window, h = 5 ft.
Distance of the sidewalk from the house, d = 12 ft.
To Find :
The length of the slope.
Solution :
We know, angle between wall and the floor is 90°.
So, we can say that the system makes an right angle triangle.
Let, length of the ramp is x.
So, Applying Pythagoras theorem in the triangle is :
[tex]x^2 = 5^2 + 12^2 \\\\x^2 = 25 + 144\\\\x^2 = 169\\\\x = 13\ m[/tex]
Therefore, the length of the ramp is 13 m.

What is the Next-Now rule and function rule for this table? 50 POINTS! BRAINLIEST TO CORRECT ANSWER.
Any unrelated answer is subject to getting their IP found and get reported.
Answer:
Step-by-step explanation:
I'm not sure what the next now rule but I can give you the function.
y = 5 * 2^x
So the table is constructed by letting 0<=x<=8
For example if x is 3
y = 5 * 2^3
y = 5 * 8 = 40
When x = 3 does y come to 40? According to the chart it does.
Try another one
y = 5 * 2*6
y = 5 * 64
y = 320 Is that what the chart records? Yes it does.
If what the text now rule means is that from the current value of y, you can get the next value, then the formula would be
y_n = 2 * y_(n - 1)
y_7 = 2 * y_6
y_7 = 2 * 320
y_7 = 640

A bottled water company bottles varying sizes of water, from 8-ounce to 1-gallon containers. The company has
determined that the mean quantity in their 20-ounce bottles is 20.8 ounces with a standard deviation of 0.6 ounces. The
bottling plant manager believes his machines are overfilling the bottles. A random sample of 30 bottles is taken, and the
mean number of ounces of water is recorded. Which of the following values of the mean of the sample is most likely to
occur if the true mean number of ounces is 20.8?
19.8
20.4
20.9
21.2
Answer:
No, since a sample mean of 20.9 or more occurred 19 out of 100 times, there is insufficient evidence that the true mean ounces of the bottles of water is greater than 20.8

Answer:
Fraction form: -1/2
Decimal form: -0.5
Step-by-step explanation:
1: Subtract 7 from both sides
7 - 6x = 9 - 2x
7 - 7 - 6x = 9 - 7 - 2x
6x = 2 - 2x
2: Add 2x on both sides
6x + 2x = 2 - 2x + 2x
-4x = 2
3: Divide both sides by -4 to get x by itself
-4x/-4 = 2/-4
x = -1/2

A triangle has two side of length 3 and 7. The third side of this triangle must not be shorter than (blank) or longer than (blank)
Answer:
The sum of two side lengths of a triangle must be greater than the length of the third.
So, if two side lengths are 3 and 7, the length of the third side must be less than 10 units.
However, it cannot be shorter than 4 units, as 3 + 4 = 7.
So your answer is: The third side of this triangle must not be shorter than 4 or longer than 10

Sandhya performed better.
Step-by-step explanation:
You can either or simplify the fractions:
[tex]\frac{630}{900}[/tex] and [tex]\frac{650}{1300}[/tex] to simpler forms like [tex]\frac{7}{10}[/tex] and [tex]\frac{1}{2}[/tex] from there you can make the [tex]\frac {1}{2}[/tex] and multiply it by [tex]\frac{5}{5}[/tex] to get [tex]\frac{5}{10}[/tex] and then from there you can see Sandya performed better.
OR
You can divide 630 by 900 and 650 by 1300
630/900 gives you 70
and
650/1300 gives you 50

Problem 4: As a salesman you are paid $250 per week plus $70 per sale. This week you want you
pay to be at least $1,200. How many sales must you make to reach your goal?
Answer
12
13
14
15
16
Answer:
14 sales
Step-by-step explanation:
1,200-250=950
70×14=970
We first need to subtract our normal pay out of the expectation.
1200-250=950 dollars
These 950 dollars have to be made from sales, and if each sale gives you 70 dollars, we just need to do simple division.
950/70=about 13.57
This meant that if we get 13 sales, we are not quite there at the goal yet, so we need to round up. Getting 14 as our answer.
