The measure of m∠14 is 110 degrees and the angle relationship is a supplementary angles
Let us assume that angle m∠10 and m∠14 are supplementary, this means that the sum of both angles will be 180 degrees.
Since the angles are supplementary, hence the required expression will be:
m∠10 + m∠14 = 180
Given that m∠10 = 70 degrees
70 + m∠14 = 180
m∠14 = 180 - 70
m∠14 = 110 degrees
Hence the measure of m∠14 is 110 degrees and the angle relationship is a supplementary angle.

The price of an item is $45.00. After a discount, the price is $38.25. What is the percent of the discount?
Answer correctly and I will give brainliest
Answer:
=15
Step-by-step explanation:
45-x% *45=38.25
(-45) x/100=38.5-45
(-45)x/100=(-6.75)
x=6.75 * 100/45
=15
The percent of the discount is 15.
It is required to find the percent of the discount.
What is percentage?A part of a whole expressed in hundredths a high percentage of students attended. Also the result obtained by multiplying a number by a percent the percentage equals the rate times the base.
Given:
Let the discount percent be x%
When the price of $45 is reduced by x%, we get $38.25.
So,
45 − x % ∗ 45 = 38.25
− 45 x /100 = 38.25 − 45
− 45 x /100 = − 6.75
x = 6.75 ∗ 100 /45
x= 15
Therefore, the percent of the discount is 15.

How do you find percentages?
Answer:
obtained number divided by total number multiply by 100%.
· Definition of Percentages
Mathematically, percentages are either numbers or ratios that are expressed as fractions of 100. They are usually denoted as "%" or simply "percent." They may be further represented as simple fractions or as decimal fractions. An example of a percentage is 65% or 65 percent. The term percentage was formed from two words, “per” and “cent.” Cent is a word with Latin and French origin that means "hundred," and "percent" means "per hundred." For example, 90 percent (or 90%) means 90 out of 100 while 50 percent (or 50%) means 50 out of 100 or half of a whole.
1. Determine the initial format of the number to be converted to a percentage
The number to be converted to a percentage can either be in the decimal or fraction format. A good example of a decimal number is 0.57, which may be the calculated ratio of the values you are comparing, while an example of a fraction is 3/20. The initial format will determine the next mathematical process to be carried out on the number.
2. Carry out a mathematical process on the number to be converted to a percentage
If the number to be converted to a percentage is a decimal number like 0.57, you may not need to do anything to it before you go to the next step. However, if it is a fraction like 3/20, you should first divide the numerator (3 in this case) by the denominator (20 in this case) to get a decimal number.
3. Multiply the result of the mathematical process by 100
If you are required to convert a decimal number like 0.57 to a percentage, you are to simply multiply it by 100. That is, 0.57 x 100 = 57. Therefore, 0.57 as a percentage = 57% or 57 percent. Another example of converting a decimal to a percentage is 0.03 x 100 = 3% or 3 percent.
However, if you are required to convert 3/20 to a percentage, you should divide 3 by 20 = 0.15. Then multiply 0.15 by 100 = 15% or 15 percent.
Another example is if you are to convert 5/10 to a percentage, you should divide 5 by 10 = 0.5. Then, multiply 0.5 by 100. Therefore, 0.5 x 100 = 50% or 50 percent.

m^ 2 + m − 90 factorize
Answer:
(m+10)(m-9)
Step-by-step explanation:
To factor this equation we want to find two numbers that multiply to -90 but also add/subtract to 1.
Those two numbers are 10 and -9 (10×-9=-90, 10-9=1)
Answer:
[tex](m-9)(m+10)[/tex]
Step-by-step explanation:
When you are given an expression in this format
[tex]ax^2+bx+c[/tex]
You must find two numbers that add up to b while the product is c.
You do trial and error to figure it out for your equation.
[tex]m^2+m-90[/tex]
Hmm... what two numbers add up to 1 and multiplied together equal -90.
Start off with pairs that can equal 90.
45 2
18 5
9 10
Ok, well 45 * 2 does equal 90 but 45 + 2 = 47and 45 + -2 = 43 but there's no way I can make it equal to 1. Next!
18 * 5 equals 90 but 18 + -5 = 13 and 18 + 5 = 23, I can just tell that there's no way I can make this equal to 1.
9 * 10 equals 90, 9 + 10 = 19 but 9 + -10 = -1. Now, that's interesting, We have -1 but we need 1. All we have to do is flip the order. 10 + -9 = 1. And -9 * 10 = -90, PERFECT!
Now use the two numbers and put it in factored form.
[tex](m-9)(m+10)[/tex]

Find the equation of the line.
A line that is parallel to the graph of 2x+3y=5 and contains the point (3,1)
Answer:
2x + 3y = 6
Step-by-step explanation:
The equation of a line in slope- intercept fprm is
y = mx + c ( m is the slope and c the y- intercept )
Given
2x + 3y = 5 ( subtract 2x from both sides )
3y = - 2x + 5 ( divide terms by 3 )
y = - [tex]\frac{2}{3}[/tex] x + [tex]\frac{5}{3}[/tex] ← in slope- intercept form
with slope m = - [tex]\frac{2}{3}[/tex]
Parallel lines have equal slopes, then
y = - [tex]\frac{2}{3}[/tex] x + c ← is the partial equation
To find c substitute (3, 1 ) into the partial equation
1 = - 2 + c ⇒ c = 1 + 2 = 3
y = - [tex]\frac{2}{3}[/tex] x + 3 ( multiply through by 3 to clear the fraction )
3y = - 2x + 6 ( add 2x to both sides )
2x + 3y = 6 ← equation of parallel line

The Swiger family recycles about 15 pounds of waste a week. This is 2/5 of the total waste a week. How many pounds of waste does the family produce each week? (Step by step explanation)
Answer: 37.5 lb/wk
Step-by-step explanation:
Let X be the total amount of waste. We are told that (2/5) of X is 15 lb/wk.
(2/5)X = 15 lb/wk
X = (5/2)*(15lb/wk)
X = (75/2) il/wk
X = 37.5 lb/wk

Quinn and Logan solved the equation 8(x-5)=8x+40. Quinn said the answer is x=0, Logan said the answer has infinitely many solutions. Who is right? Explain your answer.
Answer:
Neither of them are right
Step-by-step explanation:
First, let's actually solve this equation:
8 ( x - 5 ) = 8x + 40
Distribute on the left:
8 ( x - 5 )
( 8 x X ) + ( 8 x ( -5 ) )
8x - 40
8x - 40 = 8x + 40
Add 40 to each side:
8x = 8x + 80
Subtract 8x from both sides:
0 = 80
0 ≠ 80
There are no solutions to the equation

Which statement best describes how she should draw her line of best fit? A. The line of best fit will be horizontal. B. The line of best fit will be vertical. C. The line of best fit will increase from left to right. D. The line of best fit will decrease from left to right.
Answer:
B
Step-by-step explanation:
The line of best fit should be vertical. This answer may not be correct.
The correct statement is statement B that is the line of best fit will be vertical.
What is a scatter plot ?
A scatter plot is a graph in which the values of two variables are displayed along two axes, and any correlation is revealed by the pattern of the resulting points.
It is given that , after a particular amount of hours of sunlight, Erika made a scatterplot showing the height that a plant increased to. On the horizontal axis, the plant height was shown.
We know that in a scatter plot , the values of two variables are displayed along two axes. As the plant height was shown on the horizontal axis. The other value which is amount of hours of sunlight will be on the vertical axis.
So , the statement which best describes how Erika should draw her line of best fit i.e., the line of best fit will be vertical.
Therefore , the correct statement is statement B that is the line of best fit will be vertical.
