Is the table above proportional or non-proportional?
Answer: I think you should divide them all and if you get the same answer it’s proportional if you don’t get the same answer it’s non-proportional
Step-by-step explanation:
Answer:
It is non-proportional.
Step-by-step explanation:
The table is non-proportional because it expresses a curved line instead of a straight line.
A fruit basket contains only apples and bananas. If there are 8 apples and 13 bananas, what is the ratio of bananas to fruit? Select all that apply. 13:8
Answer:
The ratio of bananas to total fruit is 13:21
Step-by-step explanation:
Since we already know the amount of apples and pears, we can find the total. 13+8=21, and since we know the number of pears, 13, we can say that the ratio is 13:21.
Answer: 13:21
In a class of 42 students, 18 students are in the Math Club, 5 students
are in both the Math Club and the Science Club, and 14 are in neither. How many
students are in the Science Club?
Answer:
15 maybe?
Step-by-step explanation:
42 - 14 = 28
18 - 5 = 13
28 - 13 = 15
subtract the 14 because it says it is in neither.
Subtract 5 from 18 because 18 are in math and only 5 are in both math and science.
Subtract 13 from the 28 because those 13 are in math and wont be in science also.

Jamie believes that applying a scale factor of 1 would result in an enlargement. Do you agree or disagree with her claim? Explain.
Answer:
If the scale factor is 1, the figure and the image are congruent.
Step-by-step explanation:
If the scale factor is less then one, then it would be a reduction, but if the scale factor is greater then one, it would be an enlargement.

Can yall give me 4 examples of rules of exponents with answers pls?
Answer and Step-by-step explanation:
When multiplying two numbers (or variables) of the same exponent, the solution would have the exponents adding each other:
[tex]a^{x} * a^{y} = a^{x+y}[/tex]
When dividing two numbers (or variables) of the same exponent, the solution would have the exponents subtracting each other:
[tex]a^{x} / a^{y} = a^{x-y}[/tex]
When a number with an exponent is being raised to an exponent, the solution would have the exponents multiplying each other:
[tex](a^{x)^{y} } = a^{xy}[/tex]
When there are two variables in parentheses and an exponent on the outside, the exponent will power both variables:
[tex](ab)^{x} = a^{x} b^{x}[/tex]

Mrs. Kelly bought a bag of flour that holds 1623 cups of flour. Each loaf of banana bread uses 23 cup of flour.
How many loaves of banana bread can she make?
Answer:
69 loaves
Step-by-step explanation: (Sorry if you don't understand I am not that good at explaining)
First you need to divide 1,623 by 23 because each loaf is 23 cups of flour.
So 1,623 divided by 23 equals 70.56 but you can't have a fractioned number so it needs to be a whole loaf of bread so she can make 69 loaves of bread

Each pair of points lies on a line with the given slope. Find y.
Answer:
3/4
Step-by-step explanation:
If slope is 1/4, you have to assume it is multiplied by x. x in the second coordinate is 3. So you place in
1/4(x)=y
1/4(3)=y
3/4=y
And the other one is incorrect
1/4(x)=y
1/4(7)=y
1 3/4 =y

Slope-intercept form
find out the y intercept and slope
Answer:
18. Slope (m) = 1/2
Y-intercept (b) = -6
19. Slope (m) = 2
Y-intercep (b) = 8
20. y = 1/2 + 6
Step-by-step explanation:
y = mx + b
y - 2x = 8
y = 2x + 8

What is the Law of Exponents?
Answer:
The exponent of a number says how many times to use the number in a multiplication.
Example:
[tex]8^{2}[/tex] = 8 × 8 = 64
Assume that the cheetah travels an average of 40 mph to go from its resting place to a rock near a river. On the return trip to its resting place, the cheetah travels an average of 70 mph. If the cheetah traveled for 15 minutes, how many minutes did the return trip take to the nearest minute and second?
Set up the table as follows. Label the rows “To the River” and “From the River.” Label the columns “Distance,” “Rate,” and “Time (in Hours).” Let t represent the unknown quantity in the problem. Fill in the table.
Answer:
9.55 minutes
Step-by-step explanation:
x hours to go to the river
0.25-x hours to come back, since 15 minutes is 0.25 hr.
to the river 40 mph * x hours =40x miles
from the river 70 mph (0.25-x) hours=17.5-70x
those two are equal
40x=17.5-70x
110x=17.5
x=17.5/110=0.159 hours
9.55 minutes

Answer: 120
120
Step-by-step explanation:
I honestly can’t explain but I think you have to do this (actually I did the work so I’m right)
P/w = part/whole = ?/400
%/100= percent/100 = 30%/100
These numbers are equivalent
If you don’t understand the top then here is how to do the work-
400x30=12000
12000/100=120
Therefore it’s 120

There are 9 people going on a trip. They purchased coach tickets for $160, and first class tickets for $1180. The total budget to spend was $4500. How many first class tickets did they buy? How many Coach tickets did they buy? Show your work.
Answer:
Step-by-step explanation:
Given
There are 9 people going on a trip
They purchased coach tickets =$160
first class tickets =$1180
total budget to spend = $4500
Let coach tickets=X
So first class tickets=9-x
160x+1180(9-x)=4500
160+10620-1180x=4500
160x-1180x=4500-10620
-1020x=-6120
X=6120/1020
X=6
So answer
Coach tickets=X=6
First class tickets=(9-x)
=3.
