what is the measure of one interior angle of the regular 32 gon?
Answer:
180°
Step-by-step explanation:
A polygon that has 32 sides is called a triacontadigon or a triacontakaidigon.
The angles of a triacontadigon add up to 5760°.
5760÷32=180°

Step-by-step explanation:
Find the value of x.
F) 6m
G) 7.5m
H) 15m
I) 21m
Answer:
x = 6 m
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = [tex]\frac{1}{2}[/tex] h (a + b)
where h is the perpendicular height and a, b the parallel bases
Here A = 60, h = 8, a = 9 and b = x , thus
[tex]\frac{1}{2}[/tex] × 8 × (9 + x) = 60, that is
4(9 + x) = 60 ( divide both sides by 4 )
9 + x = 15 ( subtract 9 from both sides )
x = 6 m

Step-by-step explanation:
Fabian bought 223 feet of wood to build
wooden boxes. He estimates it will take 2
feet per box. How many boxes will Fabian be
able to build?
Answer:
111 boxes
Step-by-step explanation:
He bought 223 feet of wood
Each box will take 2 feet
To determine the total number of box he'll make from 223,
1 box = 2 feet of wood
X box = 223 feet of wood
X = (223 × 1) / 2
X = 111.5 box approximately 112 boxes
But technically, since its 111.5, he'll be able to make 111 boxes completely with 0.5 feet of wood left
Jose ran13

mile in 3 minutes and 15 seconds. Calculate Jose's rate in minutes per mile; in other words, the time that it would take for him to run 1 mile.
Answer:
you have to find the unit rate first then try to solve
Step-by-step explanation:
Answer:
1/4 minutes
Step-by-step explanation:
1 minute = 60 seconds
3 minutes = 180 seconds
3 minutes and 15 seconds = 195 seconds
13 miles/195 seconds
195/13 = 15
His speed --> 1 mile/15 seconds
1/4 minutes = 15 seconds

convert 20 m\s into km\hr ?
HELPPP!! PLEASEEE!
AND THANK YOUUUU
Answer: 72 km / hour
Step-by-step explanation:
Answer:
72 km/hr
Step-by-step explanation:
First, convert from meters to kilometers. 20 meters is 0.02 kilometers.
Now that you have km/s, convert 0.02 km/s into km/h by multiplying it by the number of seconds in an hour. There are 3,600 seconds in an hour. Multiply 0.02 km/s by 3,600 secs/h to get 72km/h!

Given the general form: ax + by = c How can we rewrite this general for the equation of a line, so that it is in slope intercept form? (a, b, and c are real numbers other than 0.) Hint: Substitute in values for a,b,c if you are confused) YOUR FINAL ANSWER SHOULD HAVE a,b,c in it. *
Answer:
[tex]y = \frac{c}{b} - \frac{ax}{b}[/tex] or [tex]y = \frac{c-ax}{b}[/tex]
Step-by-step explanation:
Slope intercept form is y = mx + b, so you rewrite it to equal y.
ax + by = c
by = c - ax
y = (c - ax) / b
[tex]y = \frac{c}{b} - \frac{ax}{b}[/tex]
In the image, all the lines overlap. This proves that all the equations are equal to each other.

Answer:
no 6^2 + 8^2 ≠ 12^2 so this is not a right triangle
Step-by-step explanation:
The Pythagorean theorem tells you if you have a right triangle
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
6^2 + 8^2 = 12^2
36+64 = 144
100 = 144
This is not true so this is not a right triangle
What is the measure of an angle, in degrees, if its supplement is six times its complement?
Answer:
72 degrees.
Step-by-step explanation:
We can name the measure of the angle x.
We can name the measure of the complement of it y.
Note that complementary angles add up to 90 degrees and supplementary angles add up to 180 degrees.
Using this info, we can set up two equations.
x+y=90
x+6y=180
Subtract the first equation from the second to eliminate x. You can do both ways, but I prefer to keep the equation positive.
x+6y=180
-x -y -90
5y=90
Divide both sides by 5.
y=18
The complement is 18, now we can plug that in to find x.
x+18=90
Subtract 18 from both sides.
x=72
The measure of the angle is 72 degrees.

Element X decays radioactively with a half life of 13 minutes. If there are 530 grams of Element X, how long, to the nearest tenth of a minute, would it take the element to decay to 11 grams? y = a * (.5) ^ (1/7)
Answer:
[tex]t \approx 50.4\,min[/tex]
Step-by-step explanation:
The time constant of the element X is:
[tex]\tau = \frac{13\,min}{\ln 2}[/tex]
[tex]\tau = 18.755\,min[/tex]
The decay function has the following form:
[tex]\frac{m}{m_{o}} = e^{-\frac{t}{\tau} }[/tex]
[tex]t = -\tau \cdot \ln \frac{m}{m_{o}}[/tex]
[tex]t = -(13\,min)\cdot \ln \left(\frac{11\,g}{530\,g} \right)[/tex]
[tex]t \approx 50.4\,min[/tex]

1.5(6)
9
Answer:
9
Step-by-step explanation:
I chose 9 because first you have to add 4+2 because it's in parenthesis and the other with parenthesis has no other numbers so 4+2 first then 4+2 is 6 then you multiply 6 by the 3 in the parenthesis because it is in the parenthesis then divide by 2 because 1/2 is basically dividing by 2

Find the mean absolute deviation for the set below:
62, 71, 83, 110, 501, 94, 227
Answer:
(MAD) mean absolute deviation: 114.2
Step-by-step explanation:
Mean: 62 + 71 + 83 + 110 + 501 + 94 + 227 = 1,148/7 = 164
164 - 62 = 102
164 - 71 = 93
164 - 83 = 81
164 - 110 = 54
164 - 501 = 337
164 - 94 = 70
164 - 227 = 63
Mean Absolute Deviation: 102 + 93 + 81 + 54 + 337 + 70 + 63 = 800/7 = 114.2
Answer:
Step-by-step explanation:
First, add all the numbers and count the total amount of numbers.
Once you've done that find the mean by dividing the total of the numbers by how many numbers you have.
Next make a chart, have 2 parts in the chart. Make boxes for however many numbers you have. Make another row in the chart for the distance from the mean ( how many numbers is it from the mean.)
Add all the "distance from mean" numbers and divide by total numbers, If a decimal, round up or down.
Then, you have the M.A,D ( Mean Absolute Deviation )
If a quadratic equation has no real roots, then its graph intersects the x-axis at how many points?
Answer:
It does not intersect the x axis
