Triangle to the left I did 4 x 3 = 12 ÷ 2 =6
Triangle to the right I did 2 x 4 = 8 ÷ 2 = 4
Then I did square in the middle so 5 x 4 = 20
Now i add these up 20 + 6 + 4 = 30
Hope this helps!

can someone please help me with this question
Answer:
10 sides.
Step-by-step explanation:
Two same interior angles + 72 degrees = 360.
Thus, the interior angle of the polygon is [tex]\frac{360-72}{2} =144[/tex].
The formula to find the interior angle of a polygon is [tex]\frac{180(n-2)}{n}[/tex]
[tex]\frac{180(n-2)}{n} =144[/tex]
Multiply both sides by n:
[tex]\frac{180\left(n-2\right)}{n}n=144n[/tex]
[tex]180\left(n-2\right)=144n[/tex]
Expand:
[tex]180n-360=144n[/tex]
Add 360 to both sides:
[tex]180n-360+360=144n+360[/tex]
[tex]180n=144n+360[/tex]
Subtract 144n from both sides:
[tex]180n-144n=144n+360-144n[/tex]
[tex]36n=360[/tex]
Divide both sides by 36:
[tex]\frac{36n}{36}=\frac{360}{36}[/tex]
[tex]n=10[/tex]

Answer: The mean is 6.
Step-by-step explanation: First you add all of the numbers together getting a total of 48. Next to find the mean you divide them by the total number of "dots". Lastly, you get the answer of 6 which is your mean.
Answer:
6.
Step-by-step explanation:
First you take the data on the dot plot, and write the numbers down from least to greatest.
The data set:
2,3,6,6,7,8,8,8
Now that you have the data reordered in a easier way to read, add up all the numbers that you got from the dot plot.
2+3+6+6+7+8+8+8=48
Next we count all the number in the data set we made.
2,3,6,6,6,7,8,8,8 = 8
The amount of numbers in this data is 8.
Lastly we then divide 48 by 8.
48/8= 6
So your answer is 6!
A motorboat averages 20 miles per hour (mph) in still water. It takes the boat the same amount of time to travel 3 miles with the current as it does to travel 2 miles against the current. What is the current's rate in mph?
Answer:
4 mph
Step-by-step explanation:
Let :
Boat speed = 20 mph
speed of current = x mph
Distance against current = 2 miles
Distance with current = 3 miles
speed against current will be ; 20 - x
speed with current will be ; 20 + x
Time =distance / speed against time against = time with current
Solving Mathematically ;
2/(20-x )=3/(20 +x)
2(20+x )= 3( 20-x )
40+2x = 60-3x
3x +2x=20
5x=20
x = 20 / 5
x = 4 mph
Speed of current = 4 mph
Evaluate f(-2) where f(x)=2x^3-x^2+3
Answer:
f(-2) = -17
Step-by-step explanation:
All f(-2) means is to substitute x for -2. Therefore,
2(-2)^3 - (-2)^2 + 3
2(-8) - 4 + 3
-16 - 1
-17

A, B, and C are points of tangency in the given Circle, a m equals 6, BK equals 4 in the perimeter of mkn is 34
Answer:
A
Step-by-step explanation:
according to tangent property
we get
AM=BMAN=CNBK=CKGiven that
AM=6BK=4Thus our equation is
[tex] \rm \displaystyle 2AM + 2AN + 2BK = 34[/tex]
substitute the given values
[tex] \rm \displaystyle 2.6+ 2AN+ 2.4 = 34[/tex]
simplify multiplication:
[tex] \rm \displaystyle 12+ 2AN+ 8 = 34[/tex]
simplify addition:
[tex] \rm \displaystyle 2AN+ 20= 34[/tex]
cancel 20 from both sides:
[tex] \rm \displaystyle 2AN=14[/tex]
divide both sides by 2:
[tex] \rm \displaystyle AN=7[/tex]
AN=CN
hence,CN=7
therefore our answer is A

Answer: 15:8
Step-by-step explanation:
Acacia leaves= 15 bags
Eucalyptus leaves=8 bags
A ratio compares two amounts and uses a :
We are comparing acacia leaves bags to eucalyptus leaves bags

What is the volume of the solid figure?
Solid is made up of 2 cuboids. First cuboid has length as 15 in., height as 5 in. and width as 5 in. Second cuboid has length as 5 in., height as 10 in. and width as 5 in. HELP ASAP I HAVE 1- MINUTES LEFT!!!
Answer:
The volume of the solid figure = Volume of the first cuboid + Volume of the second cuboid
The volume of the solid figure = 15×5×5 + 5×5×10
Or, The volume of the solid figure = 375 + 250
Or, The volume of the solid figure = 625 inch³
Therefore, the volume of the solid figure = 625 inch³

PLEASE HELP!!! I have no clue how to find the perimeter of MNP
Answer:
130
Step-by-step explanation:
Triangle MNP is twice the size of triangle SRP. So 2(x+4)=5x-34.
Distribute: 2x+8=5x-34
Add 34 on both sides: 2x+42=5x
Subract 2x on both sides: 42=3x
Divide both sides by 3: 14=x
If x=14, then 5x-34
is 5(14)-34=70-34=36.
The perimeter of the triangle MNP is
MN+NP+PM.
MN is 36
NP is doubled the 22 because triangle MNP is twice the size of triangle MQS. So NP is 44.
PM is doubled the 25 because triangle MNP is twice the size of triangle QNR. So PM is 50.
The perimeter of the triangle MNP is
MN+NP+PM
=36+44+50
=130
How to solve this equation?
It says use the substitution method, so you would take the bottom equation, and since it says that x is equal to that, you would use that equation in place of the x in the top equation. so it would be 9y = 3(3y+3) - 9. You then distribute the 3 into the 3y +3, which gets you 9y = 9y + 9 - 9, which is also 9y=9y. Subtract 9y to get 0 = 0, which just means that there are infinite solutions to this equation. Whenever you get 0 = 0, all that means is that there are infinite solutions to this particular set of equations. Hope this helped!
Answer:
y=y
x=3y+3
Step-by-step explanation:
[tex]\left \{ {{9y=3x-9} \atop {x=3y+3}} \right.[/tex]
[tex]9y=3x-9[/tex]
Plug the second equation [tex]x=3y+3[/tex] into the above equation as x
[tex]9y=3(3y+3)-9[/tex]
Open up the brackets
[tex]9y=3(3y+3)-9\\9y=9y+9-9\\9y=9y\\y=y[/tex]
This system of equations has infinitely many solutions.
When graphed, the two lines will overlap each other.
Therefore, y=y and x=3y+3.
I hope this helps!
There were x cupcakes at the beginning of a party. By the end of the party, 16 of them had been eaten. Using x, write an expression for the number of cupcakes that were left.
Answer: x - 16
Step-by-step explanation:
Since there were x cupcakes at the beginning of a party and at the end of the party, 16 of them had been eaten, the expression for the number of cupcakes that were left will be gotten by subtracting the number of cupcake that have been eaten from the cupcakes at the beginning. This will be:
= x - 16
For example, if there were 20 cupcakes at the beginning and 16 was eaten, the number left will be:
= x - 16
= 20 - 16.
= 4
There'll be 4 left
