Which angle relationship means two angles add up to 90
degrees?
When two angles add to 90°, we say they "Complement" each other.
So if two angles are complementary,
then the sum of their measures is 90 degrees.
For example, if we had a 62 degree angle and an 18 degree angle,
these two angles are complementary because they add to 90 degrees.

reduce the ratio of 70 and 50
Answer:
7:5
Step-by-step explanation:
70 and 50 can be divided by 10
hope this helps you :)
Answer:
7:5
Step-by-step explanation:
we will make the numbers 70 and 50 as low as they can be while still keeping the same ratio between the two numbers.
To do this we find the largest number that both 70 and 50 can be divided by. Then we divide both 70 and 50 by that number to get the new reduced ratio.
The largest number 70 and 50 can be divided by is 10. When we divide both numbers by 10, we get the new reduced ratio as follows:
7:5
Considering that the lower intersection is a translation of the upper intersection what does this mean about the measures of the corresponding angles
This mean about the measures of the corresponding angles the lower intersection is a translation of the upper intersection. This means that corresponding angles overlap each other on translation. So, the corresponding angles are congruent This is further explained below.
What is angles?Generally, angles is simply defined as the angle formed when two lines or surfaces meet, or the distance between them (typically measured in degrees).
In conclusion, What does this imply about the sizes of the associated angles Simply said, the bottom intersection is a literal translation of the higher one. What this indicates is that, when translated, the relevant angles overlap. As a result, the two angles are equal.

Answer should only contain positive exponents .
2n/n^2
I got n/n^2 .
Answer:
[tex]\frac{2}{n}[/tex]
Step-by-step explanation:
[tex]\frac{2n}{n^2}[/tex] (exponential rule for fraction is the number subtract each other)
[tex]2n^{-1}[/tex] (from the top n exponent of 1 minus bottom exponent of2 (1-2=-1))
since the n is a -1 exponent to make it positive you put it in the denominator
[tex]\frac{2}{n}[/tex]
(the reason it's not n/n^2 is that the two cannot just disappear or be taken away unless you are solving for something and the n/n^2 can also be simplified into the 1/n)

Peyton plans to deposit her next paycheck into her savings account.she makes $12.50 per hour and her next paycheck will be h hours of work the expression 12.50h + b represents the amount of money in her savings account after she deposits her next paycheck what does b represent in the expression
Answer: Current savings account balance
Step-by-step explanation:
since the equation is y = mx + b
mx would be the starting point so she earns 12.50 per hour so it's the current amount she has is 12.50.
Sorry if it dosen't make sense.
The b in the expression 12.50h + b represents the amount already in the saving account before depositing the next paycheck.
What is an expression?An expression is a sentence with a minimum of two numbers or variables and at least one operation such as addition, subtraction, multiplication, or division.
We have,
The amount earned per hour = $12.50
The amount earned in her next paycheck = $12.50h
where h = number of hours
The expression that represents the amount of money in her savings account after depositing the next paycheck:
= 12.50h + b
We need to find what b represents in this expression.
b will represent the amount already in the saving account before depositing the next paycheck.
Thus the b in the expression 12.50h + b represents the amount already in the saving account before depositing the next paycheck.

What is the midpoint between the points (3,-1) and (-9,8)?
Hey there! I'm happy to help!
To find the x value of the midpoint, you add the x values and divide by 2.
3+(-9)=3-9=-6
-6/2=-3
And for the y value you add the y values and divide by 2.
-1+8=7
7/2=3 1/2
Therefore, our midpoint is (-3,3 1/2)
