Answer:
The sum of angles of the exterior angles of a nonagon is 360°.
The perimeter of a triangle is 20 cm. The lengths of the sides are x, x + 3, and x + 5.
What is the length in centimeters of the longest side?
The side of the longest triangle would be 9cm.
Step-by-step explanation:First, we need to find x
To do this, we add all 3 sides together to get the perimeter (20) :
x + x + 3 + x + 5 = 20
3x + 8 = 20
We then use this equation to find x :
3x + 8 = 20
(minus 8 on both sides)
3x = 12
(divide by 3 on both sides)
x = 4
Now we have x, we substitute it into the longest side (x + 5)
4 + 5 = 9cm.

A cylinder has a height of 7 feet and a radius of 12 feet. What is its volume? Use ≈ 3.14 and round your answer to the nearest hundredth.
Answer: 461.6 ft^3
Step-by-step explanation:
Substitute r and h into the volume formula. In this case, the height is 12, so h = 12. The diameter is 7, so the radius is half that, or 3.5. Substitute into the formula and simplify: V=π(3.5)2(12)V=π(12.25)(12)V=147π
So the exact volume of the cylinder is 147π ft3
.
To find the approximate volume, substitute 3.14 for π
and simplify:V≈147(3.14)≈461.58
. Rounded to the nearest tenth, the approximate volume of the cylinder is 461.6 ft3
.

Brainliest plus 30 points could you help me with this its a Simplifying Radicals maze?https://drive.go ogle.com/file/d/1F4wd2VyL16D68UHnPVaZgye8niEV9Pe9/view
Okay, so it took me a few videos to understand what exactly we were supposed to be doing(your teacher wasn't exactly a ball of fire oop), but I pretty much get it now.
So basically the goal of simplification is to translate as much of the raticand as possible into whole numbers. Right now, most of the raticands are imperfect squares-- numbers whose square roots aren't whole numbers. If we ran these questions through a calculator, we'd get an answer like 17.88854382, which isn't super easy to manipulate.
Instead, we want to break that up into two parts-- the whole number and a much smaller radical. To do this, we need to find the largest factor of each raticand that's a perfect square, which is a number who has a square root of a whole number(for example 25, whose square root is 5).
For example, lets find the largest perfect square of the first problem: (I'm sure there's a better way to do this, but I just try dividing the number by 2, 3, 4, and so on until I find a perfect square)
[tex]320 \div 2 = 160( \sqrt{160} = 12.65)(imperfect) \\ 320 \div 3 = 106.67( \sqrt{106.67} = 10.32)(imperfect) \\ 320 \div 4 = 80( \sqrt{80} = 8.94)(imperfect) \\ 320 \div 5 = 64( \sqrt{64} = 8)(perfect)[/tex]
So now we know that
[tex] \sqrt{320} [/tex]
is the same as
[tex] \sqrt{64} \times \sqrt{5} [/tex]
Finally, we take the square root of 64(in this case 8) and append it to the front of the other radical, like so:
[tex]8 \sqrt{5} [/tex]
and there we go! We have successfully simplified the radical.
I want you to try this out now, and tell me if it makes sense. If it doesn't, tell Gem and I can try to clarify for you on zoom. Sorry for the delay buck, but I hope this is what you needed!

morgan has 42 inches of rope, Malcolm has 4 feet of rope and Roberto has 2 yards of rope express the total length of rope the three friends have in inches, feet, and yards.
Answer:
1) Total length in inches = 162 inches
Step-by-step explanation:
express the total length of rope the three friends have in inches, feet, and yards.
2) Total length in Feet = 13.5 feet
3)Total length in yard = 4.5 yard
a) Total length in inches
Morgan has 42 inches of rope
Malcolm has 4 feet of rope
Convert to inches
1 foot = 12 inches
4 feet = 4 × 12 inches
= 48 inches
Roberto has 2 yards of rope
Convert to inches
1 yard = 36 inches
2 yards = 2 × 36 inches
= 72 inches
Hence, the total length of rope in inches
= (42 + 48 + 72)inches
= 162 inches
2) Total length in Feet
1 inch = 0.0833 feet
162 inches = 162 × 0.0833 feet
= 13.5 feet
2) Total length in yard
1 inch = 0.0278 yard
162 inches = 162 × 0.0278 yard
= 4.5 yard

The ___
is the variable that determines the value of the output in a function
Here, we are required to identify what is the variable that determines the value of the output in a function.
The Independent variable is the variable that determines the value of the output in a function.Most mathematical functions take the form;
y(x) = polynomial in terms of x.
such as; y = 5x + 6
In the scenario above; the connotation f(x) can simply be written in words as;
y being a function of x.Consequently, the value of x is the determinant of the corresponding value of y.
This means that y(output) is dependent on x(input) and as such;
This concept is evident in Regression Analysis.
The variable y can be termed the Dependent variable and the variable x can be termed the Independent variable.

For the equation y = 2.5X, choose which ordered pairs would be on the line if it was graphed? Select ALL that apply.
(0, 0) and (-4, -10)
(-1, -2.5)
(0. 0) and (2, 5)
(3, 7.5) and (-3, -7.5)
(1, 3.5) and (2, 5)
(1, 2.5) and (3, 6.5)
Answer:
(0, 0) and (-4, -10)
(0. 0) and (2, 5)
(3, 7.5) and (-3, -7.5)
Step-by-step explanation:
We have the function:
y = 2.5*x
This is a linear relationship, with a slope equal to 2.5 and y-intercept equal to zero.
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
Then we can check with the points given in the options, and see which ones meet these two criteria.
a) (0, 0) and (-4, -10)
the slope will be:
a = (-10 - 0)/(-4 - 0) = 2.5
The slope is 2.5, then:
y = 2.5*x + b
To find the value of b, we just need to replace the values of one of the points in the equation, let's use the point (0, 0)
0 = 2.5*0 + b
0 = 0 + b
Then b = 0
y = 2.5*x
This means that these points would be on the line when graphed.
b) (0. 0) and (2, 5)
in this case the slope is:
a = (5 - 0)/(2 - 0) = 2.5
then:
y = 2.5*x + b
to find the value of b, let's use the point (0, 0)
0 = 2.5*0 + b
0 = 0 + b
b = 0
then
y = 2.5*x
This ordered pair would be on the line when graphed.
c) (3, 7.5) and (-3, -7.5)
The slope is:
a = (-7.5 - 7.5)/(-3 - 3) = 2.5
y = 2.5*x + b
The value of b will be obtained by using the point (3, 7.5)
7.5 = 2.5*3 + b
7.5 = 7.5 + b
b = 0
Then:
y = 2.5*x
This ordered pair will be on the line when graphed.
d) (1, 3.5) and (2, 5)
The slope is:
a = (5 - 3.5)/(2 - 1) = 1.5
The slope is different than 2.5, then we can discard this pair.
e) (1, 2.5) and (3, 6.5)
the slope is:
a = (6.5 - 2.5)/(3 - 1) = 2
Again, the slope is different than 2.5, then this option can be discarded.
We can conclude that the ordered pairs that will be graphed are:
(0, 0) and (-4, -10)
(0. 0) and (2, 5)
(3, 7.5) and (-3, -7.5)
