Mr. F's bathtub drains at a rate of 2 gallons per minute but fills at 3.5 gallons per minute. After a 4000-calorie dinner, Mr. F forgot to close the drain before filling his 60 gallon tub. How long did it take for the tub to fill? Express your answer in minutes.
Answers
40 minutes
Step-by-step explanation:
It will take 40 minutes because if the water drains at a rate of 2 gallons a minute but fills at 3.5 gallons a minute, that will mean that the water will still fill at 1.5 gallons per minute.
If you multiply 1.5 gallons by 20 minutes the tub will be half full with 30 gallons of water so that means if you multiply 20 minutes by 2 it will mean that the tub will have 60 gallons of water and it would have taken 40 minutes to fill.

Multiple select question
A)
I could use a mapping diagram. If more than one arrow points from an input value to the output values, I know it is not a function.
B)
I could use a straight object like a pencil. If the pencil intersects a graph at more than one point when it is held vertically, I know it is not a function.
C)
I could use a table. If I see that there is more than one output for an input, then the relation is a function.
D)
I could use a straight object like a pencil. If the pencil intersects a graph at more than one point when it is held horizontally, I know it is not a function.
E)
I could use a mapping diagram. If more than one arrow points from an output value to the input values, I know it is not a function.

Answer:
C, Identify the input values. Identify the output values. If each input value leads to only one output value, classify the relationship as a function. If any input value leads to two or more outputs, do not classify the relationship as a function.

The table shows the balances of two bank accounts for 3 months. In what month will the balance of Account A be equal to the balance of Account B? I have a pic below
Answers
x can represent the number of months and y can represent the account balance
account a: y=35x + 150
this is because the balance starts at $150 and increases by $35 every month
account b: y=15x+450
this is because the balance starts at $450 and increases by $15 every month
now we use substitution (making equations equal to each other) to solve for x, the number of months it will take for the balances to be equal
35x+150=15x+450
-150 -150
35x=15x+300
-15x -15x
20x=300
/20 /20
x=15
On month 15, the balances of both accounts will be equal.

There are 15 sedans on a used car lot, along with 54 other vehicles.
What is the probability that a randomly selected vehicle will be a sedan?
Write your answer as a fraction or whole number.
Answers
Answer:
5/23
Step-by-step explanation:
54+15=69
15/69=5/23
The Probability of selecting a sedan is 22%.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The degree to which something is likely to happen is basically what probability means.
Given that there are 15 sedans and 54 other vehicles, the total number of vehicles on the lot is:
Total number of vehicles
= Number of sedans + Number of other vehicles
= 15 + 54
= 69
So, the Probability of selecting a sedan
= Number of sedans / Total number of vehicles
= 15 / 69
= 5/23
= 0.22
= 22%

Carmela mixes 3/4 kilograms of walnuts, 1/2 kilograms of almonds,and 1/4 kilograms of pecans together. She divides the mixed nuts into 3/10 kilogram bags. How many bags of mixed nuts does she have. PLEASE HELP DUE TOMORROW.
Answers
Answer:
5 bags of mixed nuts.
Step-by-step explanation:
First, we add the amount of nuts together.
3/4 + 1/4 = 1
1 + 1/2 = 1 1/2
1 1/2 = 3/2 as an improper fraction.
Then we divide 3/2 by 3/10
To divide fractions, use "Keep, Switch, Flip"
Keep the first number, switch the sign, and flip the second fraction.
3/2 * 10/3 = 30/6 = 5.

Answers
Answer:
Step-by-step explanation:
1
perimeter = 9 · 4 = 36 m
area = 9² = 81 m²
2
perimeter = (10+14) · 2 = 24 · 2 = 48 in
area = 10 · 14 = 140 in²
3
width = 63 : 7 = 9 km
9 · 2 = 18 km
7 · 2 = 14 km
area = 18 · 14 = 252 km²
4
A 300 : 30 = 10
(10 + 30) · 2 = 40 · 2 = 80 (no)
B
(20 + 5) ·2 = 25 · 2 = 50 yd (ok)
C
perimeter is 48 yd (ok)
D
(22 +26) · 2 = 48 · 2 = 96 yd (no)
E
(16 + 14) · 2 = 30 · 2 = 60 yd (no)
F
length = 162 : 9 = 18 yd
(18 +9) · 2 = 27 · 2 = 54 yd (ok)
Answer:
1
perimeter = 9 · 4 = 36 m
area = 9² = 81 m²
2
perimeter = (10+14) · 2 = 24 · 2 = 48 in
area = 10 · 14 = 140 in²
3
width = 63 : 7 = 9 km
9 · 2 = 18 km
7 · 2 = 14 km
area = 18 · 14 = 252 km²
4
A 300 : 30 = 10
(10 + 30) · 2 = 40 · 2 = 80 (no)

Step-by-step explanation:[tex]\frac{2(m+2)}{2}[/tex]
step 1
2(m+2)=22=2x11
step 2
:[tex]\frac{2(m+2)}{2}=\frac{2*11}{2}[/tex]
step 3
(m+2)=11
step 4

Answer: (see below)
Step-by-step explanation:
2 distributed to each term inside 2(m + 2) looks like this:
2m + 4
first multiply 2xm, then 2x2
Now you have an expression where you can solve for m:
2m + 4 = 22
2m = 22 - 4 = 18
m = 18/2 = 9
Dan is cutting 4.75-foot lengths of twine from a 249-foot spool of twine. He needs to cut 42 lengths and says that 40.5 feet of twine will remain. Show that this is reasonable.
Answers
To show that Dan's statement is reasonable, we can set up an equation to represent the situation. Let's let x represent the number of feet of twine that Dan has cut.
We can then set up the following equation: [tex]4.75x = 249 - 40.5[/tex]
Solving for x, we find that x = 42. This means that Dan has cut 42 lengths of twine, which is what he said he would do.
Since the number of lengths of twine that Dan has cut and the amount of twine that will remain match what Dan said, his statement is reasonable.
