The sum of the angles in a triangle are 180 degrees. Find the value of the variable, then find the angle measures of a polygon.
Answer:
15=x 5x=75
Step-by-step explanation:
90/6=15
6 is how many x's there are in total meaning that 1 x = 15
15*5=75 so one angle is 15 while the other is 75
75 + 15= 90
90+90=180 getting you the 180 degrees
Select an equation to solve the problem. Then solve. Joaquin is saving $369 to buy a surf board. He saved $9 each week for 11 weeks. He wants to buy the surf board in 9 more weeks. How much does Joaquin need to save each week? Let m be how much money Joaquin needs to save each week. Select an equation to solve the problem. ? Solve the equation. M = Answer the question. Joaquin needs to save $ each week.
Answer:
[tex]9m = 270[/tex]
[tex]m = \$30[/tex]
Joaquin needs to save $30 each week.
Step-by-step explanation:
Total money required for buying a surf board = $369
Money saved every week for first 11 weeks = $9
Total money saved in first 11 weeks = 11 [tex]\times[/tex] 9 = $99
Joaquin wants to buy the surf board in 9 more weeks.
To find:
Money to be saved each week for the next 9 weeks so that the surf board can be bought?
Solution:
Let the money to be saved each week for the next 9 months = $[tex]m[/tex]
Total money to be saved in the next 9 months = $9[tex]m[/tex]
Now, let us find the remaining amount of money to be saved by subtracting the total money saved from the cost of surf board. And then compare it with $9[tex]m[/tex].
[tex]369 - 99 = 9m\\\Rightarrow 9m = 270[/tex]
Solving the equation, we get:
[tex]m = \$30[/tex]
Therefore, Joaquin needs to save $30 each week.
List the sides from least to greatest

15. Scarlett estimated that there were 50 pieces of candy left in her Halloween basket. When she counted,
there was actually only 46 pieces left. What was her percent error?
Answer: 8% Error
Step-by-step explanation:
Lets go ahead and change the equation to a format that we're more familiar with.
Original:
50 -> 46
But what's easier is if we are working with 100's because of 100% right?
So lets do this.
100 -> 92
All I did was multiply both by 2 to get 100 to 92. Now it's easier to determine because of what we're looking at. 100-92 is 8% which also makes 50 to 46 an 8% error because of the symmetry between both equations. Enjoy!

Kellan’s lemonade recipe uses 4 scoops of lemonade powder for every 2.5 cups of water. Kellan uses 10 scoops of lemonade powder to make a batch of lemonade. How much water should he use?
Answer:
6.25 cups of water
Step-by-step explanation:
So I first write out the rates: 4:2.5 and also 10:?
So let's find out how the scoops changed, as in how did you get 4 to become 10 so you can do the same thing to 2.5 and get ?.
To go from 4 to 10 you MULTIPLY/DIVIDE. DON'T ADD OR SUBTRACT. 10 divided by 4 (to see what you multiplied by) is 2.5.
So we multiplied 4 by 2.5 to get 10. So if we multiply 2.5 by 2.5 we get 6.25.
So 4:2.5 = 10:6.25
?=6.25

The lengths of the four sides of a quadrilateral (in inches) are consecutive integers. If the perimeter is 110 inches, find the value of the longest of the four side lengths.
The longest side of the quadrilateral (in inches) is 29 inch.
Here,
The lengths of the four sides of a quadrilateral (in inches) are consecutive integers.
The perimeter is 110 inches.
We have to find the value of the longest side of the four side lengths.
What is Perimeter of quadrilateral?
The sum of all length of sides of a quadrilateral is called the Perimeter of quadrilateral.
Now,
The lengths of the four sides of a quadrilateral (in inches) are consecutive integers.
Let the length of quadrilateral are;
x, x + 1, x + 2 and x + 3
The longest length = x + 3
Since, The perimeter is 110 inches.
Hence,
x + (x + 1) + (x + 2) + (x + 3) = 110
x + x + 1 + x + 2 + x + 3 = 110
4x + 6 = 110
4x = 110 - 6
4x = 104
x = 26 inch
Hence, The longest length = x + 3 = 26 + 3 = 29 inch
Therefore, The longest side of the quadrilateral (in inches) is 29 inch.

During the first leg of a backpacking trip, a group of hikers covered 10.4 miles in 3 hours and 1 minute. The next day, the group hiked 8.6 miles in 3 hours and 47 minutes. What was the group's average speed over the two days? Answer as a decimal rounded to the nearest tenth.
Answer:
2.79 mi/hr ( for the time they were actually moving)
Step-by-step explanation:
average speed = total distance / total time
= ( 10.4 + 8.6 mi) / ( ( 181 + 227 min )/60 min/hr) =2.79 mi/hr
The sum of two numbers is 54. The larger number is 16 more than the smaller number. What are the numbers?
Answer: 19, 35
Step-by-step explanation:
Two numbers: x and y.
x+y=54
x+16=y
x+x+16=54
2x+16=54
2x=38
x=19
19+y=54
y=35
19, 35
Answer:
x = 35
y = 19
Step-by-step explanation:
16 + x + y = 54
-16 -16
x + y = 38
÷2
x = 19
y = 19
The larger number is 16 more than the smaller number
x = 19 + 16 = 35
x = 35
y = 19
35 + 19 = 54
54 = 54

If f(x)=49-x^2 and g(x)=7-x, which is the rule of the function (f-g)(x)?
A. -x^2-x-56
B. -x^2+x+42
C. 7+x
D. x^3-7x^2-49x=343
Answer:
B
Step-by-step explanation:
(f - g)(x) = f(x) - g(x), then
f(x) - g(x)
= 49 - x² - (7 - x) ← distribute by - 1
= 49 - x² - 7 + x ← collect like terms
= - x² + x + 42 → B

In kickboxing, it is found that the force, f, needed to break a board, varies inversely with the length, l, of the board. If it takes 15 pounds of pressure to break a board that is 7 feet long, how many pounds of pressure will it take to break a board that is 5 feet long?
Answer:
21 pounds
Step-by-step explanation:
Given that f varies inversely with l then the equation relating them is
f = [tex]\frac{k}{l}[/tex] ← k is the constant of variation
To find k use the condition f = 15 when l = 7, then
15 = [tex]\frac{k}{7}[/tex] ( multiply both sides by 7 )
105 = k
f = [tex]\frac{105}{l}[/tex] ← equation of variation
When l = 5 , then
f = [tex]\frac{105}{5}[/tex] = 21 pounds

What is the main difference between vascular and non-vascular plants? *
Suppose you find a plant that has a woody stem and is taller than you. Would you classify the plant as vascular or non-vascular. Explain. *
-science
Answer:
The main difference between a vascular and a non-vascular plant is that a vascular plant has vessels that can carry food and water to all the other parts of the plant. the arrangements of the cell in a non-vascular plant is also a lot simpler.
Step-by-step explanation:
I would classify the plant as vascular because vascular plants tend to be really tall and large in comparison to non-vascular plants.
