If the measure of one exterior angle of a regular polygon is 40 degrees, how many sides does the polygon have?
Answer:
The polygon has 9 sides
Step-by-step explanation:
we know that
A regular polygon has equal length sides and equal interior angles
step 1
Find the measure of the interior angle
Remember that
The interior angle plus the exterior angle must be equal to 180 degrees (form a linear pair)
Let
x ----> the measure of each interior angle in the regular polygon
so
[tex]x+40^o=180^o[/tex]
solve for x
[tex]x=180^o-40^o=140^o[/tex]
step 2
Find the number of sides of the regular polygon
we know that
The measure of each interior angle in a regular polygon is given by the formula
[tex]x=\frac{(n-2)180^o}{n}[/tex]
where
n is the number of sides of the polygon
substitute the given values
[tex]140^o=\frac{(n-2)180^o}{n}[/tex]
solve for n
[tex]140n=180n-360\\180n-140n=360\\40n=360\\n=9\ sides[/tex]
therefore
The polygon has 9 sides

If a Subway train traveled 12 km in 8 minutes how many km/h was the train going?
Answer: 1.5 km/h
To find the speed use this:
distance/ time
12/8
Answer:
90km/h
Step-by-step explanation:
set up as this: 12km/8min = x/60min then cross multiply
12*60 = 720
8*x = 8x
solve for x
720 = 8x
90 = x

Step-by-step explanation:
So what are you looking for with that equation?
Which equation is equivalent to the square root of x^2 + 81 = x + 10 (I put a picture up with the question and answers)
Answer:
See below
Step-by-step explanation:
sqrt(x^2+81)=x+10
x^2+81=x^2+20x+100 (which is one of the options)
81=20x+100
-19=20x
x=-19/20
So there's the work done.

joyce has between 25 to 75 coloured beads. when she makes them into groups of 9, 8 beads are left out. when she groups into groups of 8, 6 beads are left out,how many beads are left
Answer:
Joyce has total 62 colored beads.
Step-by-step explanation:
For making groups of 9, let the number of beads be x.
total beads = 9x + 8
For making groups of 8, let the number of beads be y.
total beads = 8y + 6
As the total number of beads in both cases are same so,
9x + 8= 8y + 6
or, 9x-8y = -2
Now lets check the values through hit and trial;
First check; x=6, y=7
9*6 - 8*7 = -2
or, 54- 56 = -2
or, -2 =-2
This satisfies our equation.
Hence; Total beads = 9*6 + 8 = 62
The total number of beads joyce had is 62.
Number of beads she have is 62 .
Step-by-step explanation:
Here we have , joyce has between 25 to 75 colored beads. when she makes them into groups of 9, 8 beads are left out. when she groups into groups of 8, We need to find how many beads are left . Let's solve this:
when she makes them into groups of 9, 8 beads are left out equation is
[tex]9x+8[/tex]
when she groups into groups of 8 , 6 beads are left out, equation is
[tex]8y+6[/tex]
Equating both equation's we get:
⇒ [tex]9x+8 = 8y+6[/tex]
⇒ [tex]9x-8y = -2[/tex]
By hit & trial method , we put x = 6 & y=7:
⇒ [tex]9(6)-8(7) = -2[/tex]
⇒ [tex]54-56= -2[/tex]
⇒ [tex]-2= -2[/tex]
Since , LHS = RHS x = 6 & y=7 satisfies the equation [tex]9x+8 = 8y+6[/tex] . So putting value of x=6 in [tex]9x+8[/tex] we get:
⇒ [tex]9x+8[/tex]
⇒ [tex]54+8[/tex]
⇒ [tex]62[/tex]
Therefore, Number of beads she have is 62 .
find the mean:
23,91,83,31,49,11,60,92
Answer:
55
Step-by-step explanation:
For the mean you add together all of the values, and then divide the sum by the number of digits there are.
23+91+83+31+49+11+60+92 = 440
440/8 = 55
23 + 91 + 83 + 31 + 49 + 11 + 60 + 92 = 440/8 = 55
Mean: 55.

)) Rachel is using ribbon to create girls' hair barrettes. For a craft fair in Springfield, she
made 12 small barrettes and 12 large barrettes, using a total of 156 yards of ribbon. Then,
for another craft fair in Norwood, she made 10 small barrettes and 11 large barrettes, which
used a total of 138 yards. How many yards of ribbon does Rachel use for each?
Answer:
small: 5 yardslarge: 8 yardsStep-by-step explanation:
Using s and L to represent the amount of ribbon used for small barrettes and large barrettes, respectively, we have ...
12s +12L = 156
10s +11L = 138
Dividing the first equation by 12 gives ...
s +L = 13
Substituting s = 13-L into the second equation gives ...
10(13 -L) +11L = 138
130 +L = 138 . . . . . . . simplify
L = 8 . . . . . . . . . . subtract 130
s = 13 -8 = 5 . . . . find s
Rachel uses 5 yards for a small barrette, and 8 yards for a large barrette.

Find the measure of < B
The measure of angle b is 25°.
Solution:
Given data:
The "L" shape angle is a right angle.
Right angle is splitted by another line and two angles are formed.
One angle is 65° and the other angle is b.
Let us find the other angle b.
65° + m∠b = 90°
Subtract 65° from both sides of the equation.
m∠b = 90° – 65°
m∠b = 25°
Hence the measure of angle b is 25°.

At a baseball game, a vendor sold a combined total of 232
sodas and hot dogs. The number of sodas sold was three times the number of hot dogs sold. Find the number of sodas and the number of hot dogs sold.
Answer:
Step-by-step explanation:
sodas ----x
hot dogs ---- y
x = 2y
x+y = 192
2y + y = 192
3y=192
y = 64
64 hotdogs and 128 sodas
2x + 3y = 2
x + 6y = 4
Answer:
x=0 and y=2/3
Step-by-step explanation:
Multiply top equation by 2 -> 4x+6y=4
Cancel out the "6y"s by elimination -> 3x=0
Divide both sides by 3 -> x=0
Plug x=0 into x+6y=4 to get y -> 0+6y=4 -> 6y=4 -> y=4/6=2/3
So x=0 and y=2/3

The ratio of the dimensions will be the same for a similar rectangle.
12/16 = 3/4 . . . given rectangle
__
18/24 = 3/4 . . . choice A is similar
9/14 ≠ 3/4 . . . . choice B is not similar
6/10 = 3/5 . . . . choice C is not similar

If 5 bags weigh the same as 3 blocks, how many blocks will 9 bags weigh?
The weight of 9 bags is 5.4 blocks
Solution:
Given that,
5 bags weigh the same as 3 blocks
We have to find how many blocks will 9 bags weigh
Let "x" be the weight of 9 bags
Then,
5 bags weigh the same as 3 blocks
9 bags weight the same as "x" blocks
From proportion we can say,
5 : 3 : : 9 : x
Therefore,
[tex]\frac{5}{3} = \frac{9}{x}\\\\5x = 27\\\\x = 5.4[/tex]
Thus the weight of 9 bags is 5.4 blocks
9 bags will be equal to 5.4 blocks
Step-by-step explanation:
Step 1 :
Given,
Weight of 5 bags = weight of 3 blocks
We need to find the weight of 9 bags
Step 2 :
From step 1 , we get
Weight of 1 bag = weight of 3 blocks ÷ 5
The weight of bags is in direct proportion to the weight of the blocks.
Hence
Weight of 9 bags = 3 blocks × 9 ÷ 5
= [tex]\frac{27}{5}[/tex] blocks = 5.4 blocks
Step 3 :
Answer :
9 bags will be equal to 5.4 blocks

6. On day 1 of a bake sale, the group sold 125 chocolate chip cookies and 75 oatmeal cookies. They also received donations that
totaled $46. They raised $196 on day 1. Both types of cookies were sold for the same price. Write and solve an equation to find
how much they charged for each cookie.
Answer:$1.33
Step-by-step explanation: What I did is I subtracted the 46 dollars in donations from the total they raised on day 1 to get the amount for just the cookies $150. Then I added the amount of the 2 total of cookies sold = 200. Then, I took the amount of cookies sold and divided it by the amount they made selling the cookies = 1.33. 200 ÷ 150 = 1.33
