NoWhich statement best explains the relationship between
lines AB and CD?
-They are parallel because their slopes are equal.
-They are parallel because their slopes are negative
reciprocals.
-They are not parallel because their slopes are not
equal.
-They are not parallel because their slopes are
negative reciprocals.
Answer:
they are parallel because their slopes are equal
Answer:
They are parallel because their slopes are equal.
Step-by-step explanation:
Find the slope using the points indicated on each line
The slope of AB
m = rise/run = 6/8 = 3/4
The slope of CD
m = rise/run = 3/4
They are parallel because their slopes are equal.

Inequalities definition
Answer:
a inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size.
Step-by-step explanation:
hope it helps :)
Answer:
In Algebra, inequality is a Mathematical statement that shows the relation between two expressions using the inequality symbol. The expressions on both sides of an inequality sign are not equal. It means that the expression on the left-hand side should be greater than or less than the expression on the right-hand side or vice versa. If the relationship between two algebraic expressions is defined using the inequality symbols, then it is called literal inequalities. If two real numbers or the algebraic expressions are related by the symbols “>”, “<”, “≥”, “≤”, then the relation is called an inequality.

-9.24 + (-2.89)
how do i do this problem? please help, i will mark you brainliest!!
Answer:
-12.13
Step-by-step explanation:
To add two negative numbers, drop the negative signs and add the two positive numbers. Then make the answer negative.
-9.24 + (-2.89) =
We are adding two negative numbers, -9.24 and -2.89.
Step 1: ignore the negative signs and add the number 9.24 + 2.89
9.24 + 2.89 = 12.13
Step 2: the answer is negative, so add a negative sign to the sum above.
-9.24 + (-2.89) = -12.13

A car's gas mileage is the distance it can go using 1 gallon of gas (measured in miles per gallon).
Based on the graph, what is this car's gas mileage? Explain.
Answer:
20 mpg
Step-by-step explanation:
Answer:
The car is traveling 20 miles per gallon.
Step-by-step explanation:
There are two ways you can solve this.
1) Since this is a graph of the car's gas mileage, all you have to do is look to find the miles for one gallon, which is plotted in this case. As you can see, for one, it is plotted halfway between 0 and 40, so that means the mile number would be 20. Looking at this, the car travels 20 miles per gallon.
2) You can also look at the point at the top that is clearly defined, and the point is (12, 240), 12 gallons used for 240 miles. To get the exact number of miles for one mile, you would divide 12 and 240 both by 12, which results in (1, 20). Since it is miles per gallon, the car gas mileage is 20 miles per gallon.

Gina has 48 stickers 3/8 are flowers, 1/8 were plants, how many are people
Answer:
Hello!
Judging by the question you have provided I have deduced that the correct answer is:
24 people
Step-by-step explanation:
To come across this answer I assumed that [tex]\frac{3}{8}[/tex] of the stickers are flowers, [tex]\frac{1}{8}[/tex] of the stickers are plants, and the wrest of the stickers are people.
I then realized that I could look at the equation this way:
If we already know how many stickers are not people, we can then add up the amount of stickers we know are not people, and then subtract that amount from the total amount of stickers to figure out how many left can be people!
Which in this case would be:
[tex]\frac{3}{8}[/tex] (not people)+ [tex]\frac{1}{8}[/tex] (not people) = [tex]\frac{4}{8}[/tex] stickers that are not people, or if simplified [tex]\frac{1}{2}[/tex] or half of the total number of stickers.
We now know that half of the stickers are not people, so thus we can deduce that the other half of the stickers are people.
And half of 48 is:
24
Thus, 24 stickers are people!
And the other 24 have to be flowers and plants!

A group of 200 adults were asked whether they prefer getting their news from newspapers or from TV. The gender of the adults and their responses are
reported in the following table.
Newspapers
Women 30
Men 50
TV
52
68
(a) What percentage of the adults are women?
(b) What percentage of the adults prefer TV?
Answer:
41% of adults are women.
60% of adults prefer TV.
Step-by-step explanation:
Women 30 Newspaper 52 TV 82 In Total so the percentage would be 82 out of 200 which would be 41 therefore 41% of adults are women.
TV scores 52 + 68 = 120 therefore 120 out 200 is the percentage of the adults that prefer TV 60 therefore 60% of the adults prefer TV.
The percentage of the adults prefer TV is 60%.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, a group of 200 adults were asked whether they prefer getting their news from newspapers or from TV.
Here,
Newspapers TV
Women 30 52
Men 50 68
Number of women =30+52
= 82
a) Percentage of the adults are women
= 82/200 ×100
= 41%
b) Percentage of the adults prefer TV
Number of adults watch TV = 52+68
= 120
Here, 120/200 ×100
= 60%
Therefore, the percentage of the adults prefer TV is 60%.

What is 34% of 375?
Answer: 127.5
Step-by-step explanation:
Question: What is 34% of 375
Percentage solution with steps:
Step 1: Our output value is 375.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above, 375=100%
Step 4: Similarly, X=34%
Step 5: This results in a pair of simple equations:
375=100% (1)
X=34%(2)
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
375/X = 100%/34%
Step 7: Again, the reciprocal of both sides gives:
X/374=34/100
X=127.5
Therefore, 34% of 375 is 127.5
