find the number of side
Answer:
The sum of interior angles of a regular polygon is 720 degree 720 720 Degree find the measure of each interior angle of the polygon
Since each angle is equal, 720 is split into 6 equal parts. So, 720/6 = 120 degrees is the measure of each interior angle.

A single die is rolled twice. Find the probability of rolling an odd
number the first time and a number greater than 4 the second time.
Step-by-step explanation and answer:
The 6 sides of the die are numbered 1,2,3,4,5,6
There are 3 odd and 3 even numbers
probability of an odd number on 1st roll is:
3/6=1/2
When you want A AND B probabilities, you multiply
the events A and B
The number less than 3 are 1,2, so the probability is:
2/6=1/3
so the probability of both events are going to be:
(1/2) *(1/3)=1/6

how many times did the decimal point move if 1.56 went to 1560
Answer:
For 1.56 to get to 1560 the decimal point moved three times.
Step-by-step explanation:
To explain this I will give a visual representation.
We have to get from 1.56 to 1,560 and find out how many times it moved forwards.
0). 1.560
1). 15.60
2). 156.0
3). 1,560
as you can see it moved three times.
1/8 divided by ? = 1/40
fill in the question mark
Answer:
5
Step-by-step explanation:
1/8 divided by 5 equals 1/40
Answer:
[tex]\frac{\frac{1}{8}}{5}=\frac{1}{40}[/tex]
Step-by-step explanation:
Let 'x' be the number to which 1/8 had to be divided to get 1/40
so the equation becomes
[tex]\frac{1}{8}\div \:x=\frac{1}{40}[/tex]
[tex]\frac{\frac{1}{8}}{x}=\frac{1}{40}[/tex]
[tex]\frac{1}{8x}=\frac{1}{40}[/tex]
[tex]\mathrm{Apply\:fraction\:cross\:multiply:\:if\:}\frac{a}{b}=\frac{c}{d}\mathrm{\:then\:}a\cdot \:d=b\cdot \:c[/tex]
[tex]1\cdot \:40=8x\cdot \:1[/tex]
[tex]40=8x[/tex]
switch sides
[tex]8x=40[/tex]
Divide both sides by 8
[tex]\frac{8x}{8}=\frac{40}{8}[/tex]
[tex]x=5[/tex]
x=5 is the number.
Therefore,
1/8 divided by 5 = 1/40
i.e.
[tex]\frac{\frac{1}{8}}{5}=\frac{1}{40}[/tex]
SOLUTION CHECK
[tex]\frac{\frac{1}{8}}{5}[/tex]
[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{\frac{a}{b}}{c}=\frac{a}{b\cdot \:c}[/tex]
[tex]=\frac{1}{8\cdot \:5}[/tex] ∵ [tex]\frac{\frac{1}{8}}{5}=\frac{1}{8\cdot \:5}[/tex]
[tex]=\frac{1}{40}[/tex]
What is the mean?

Step-by-step explanation:
3+0+4+7+0+4+5+3+6+8/10
40/10
4
Answer:
The mean is 4.
Step-by-step explanation:
When you add 3+0+4+7+0+4+5+3+6+8 you get 40 and because there are 10 numbers you would divide 40 by 10 and get 4.
Mean-the average of all of the numbers in a data set...to find the mean you simply add all of the given numbers together and then divide that sum by the total amount of numbers given, then you will get your mean.

y = -1
Step-by-step explanation:
-2x + 5y = -17 ------ equation 1
3x- 10y = 28 ------- equation 2
equation 1× 2
-4x + 10y = -34 ------- equation 3
equation 2 + equation 3
-x = -6
x = 6
x = 6 substitute for equation 1
-12 + 5y = -17
5y = -5
y = -1
