The density in pounds per pint is 0.047 pounds per pint
Density is calculated using the formula -
Density = [tex]\frac{mass}{volume}[/tex]
To find the density in pounds per pint, we will convert mass and volume to the respective units.
Converting mass in kilograms to pounds -
1 kilogram = 2.205 pounds
9 kilograms = [tex]\frac{2.205*9}{1}[/tex]
9 kilograms = 19.84 ppounds
Converting volume in cubic feet to pints -
1 cubic foot = 59.844 pints
7 cubic foot = [tex]\frac{59.884*7}{1}[/tex]
7 cubic foot = 418.9 pints
Now, keeping the values in formula to find density
Density = [tex]\frac{19.84}{418.9}[/tex]
Performing division to find density -
Density = 0.047 pounds per pint
Hence, the density in pounds per pint is 0.047.

Jim's science class is making slime from cornstarch and glue. Jim is helping pass out materials. He gives each student 80 grams of cornstarch from a 2-kilogram bucket. If Jim's class has a total of 21 students, how many grams of cornstarch will he have left?
The total amount of corn starch left is 320 grams.
How to find the grams of corn starch left?He gives each student 80 grams of corn starch from a 2-kilogram bucket.
Each students collected 80 grams of corn starch.
Therefore,
1 student = 80 grams of corn starch
His class has a total of 21 students.
Therefore,
total mass of corn starch distributed = 21 × 80
total mass of corn starch distributed = 1680 grams
The corn starch from the bucket = 2 kg
1kg = 1000 g
2kg = 2000g
Hence,
The corn starch from the bucket = 2000 grams
Finally,
amount in grams of corn starch left = 2000 - 1680
amount in grams of corn starch left = 320 grams.

Answer:
250x + 525y ≤ 7800
no, 15 refrigerators and 8 pianos will not fit on the truck
Step-by-step explanation:
we know that x is the refrigerators and each one is 250 lbs
this can be written as 250x
we know that y is the pianos and each one is 525 lbs
this can be written as 525y
we also know that "no more than" is the same that as less than equal to
so this can be written as ≤
we can also say that the refrigerators and pianos has to be ≤ 7800
so now we have: 250x + 525y ≤ 7800
plug in 15 to x and 8 to y
250(15) + 525(8) ≤ 7800
3750 + 4200 ≤ 7800
7950 ≤ 7800
this statement is not true so no, 15 refrigerators and 8 pianos will not fit on the truck

Answer:
y = -1.50x + -3
---------------------------------------------
Step 1: Calculating Slope (m).
m = y2-y1/x2-x1
m = 3-0/-4--2
m = 3/-2
m = -1.50
Now putting value of m in equation (i)
y = -1.50x + b
Step 2: Calculating Y-intercept (b).
Lets choose the first point, (-2,0) for calculating y-intercept:
y = mx + b
0 = -1.50(-2) + b
0 = 3 + b
-3 = b
b = -3
Now putting value of b in equation
y = -1.50x + -3

the adams family and the green family each used their sprinklers last summer. the water output rate for the adams family's sprinkler was per hour. the water output rate for the green family's sprinkler was per hour. the families used their sprinklers for a combined total of hours, resulting in a total water output of . how long was each sprinkler used?
The duration of the sprinkler used by each families are-
Adams family: 25 hoursGreen family: 30 hoursWhat is linear equation in two variables?Linear equations in two variables are equations with one, none, and infinitely many solutions where each of the two variables has the highest exponent order of 1.
A two-variable linear equation has the standard form ax + by + c = 0, where x and y are the variables. The solutions could also be composed in pairs, such as (x, y).Now, as per the given question;
Let the total time taken by Green family is 'x'.
Let the total time taken by Adams family is 'y'
The total time for which the sprinkler are used is 55 hours.
Thus, x + y = 55 (equation 1)
The water output rate for the Green family's sprinkler was 30 L per hour.
The water output rate for the Adams family's sprinkler was 20 L per hour.
The total output of the water is 1400 L.
Then,
30x + 20y = 1400 (equation 2)
Substitute the value of x from equation 1 in equation 2.
30(55 - y) + 20y = 1400
Dividing whole equation by 10.
3(55 - y) + 2y = 140
Solving the equation.
165 - 3y + 2y = 140
y = 165 - 140
y = 25 hours. (Time for which Adams family used the sprinklers)
Put value of y in equation 1 to find x.
x = 55 - y
x = 55 - 25
x = 30 hours. (Time for which Green family used the sprinklers)
Therefore, the time for which both of the families used the sprinklers is estimated.

help! I only have a certain amount of time.... easy points! The sum of 3 times a number and 4 is 13. Find the number.
Answer:
The number is 3
Step-by-step explanation:
Ok, first thing's first: we need to make the words into an actual equation.
since it just says a number I'll use x
3 times x + 4 = 13
3x +4 =13
Now that we have our equation, we can solve for x
3x + 4 = 13
-4 -4
3x = 9
I subtracted 4 on both sides to get rid of the 4 and move it to the other side of the equation, so we can try to get x by itself.
3x =9
/3 /3
x = 3
I divided both sides by 3 to get rid of the 3 that's being multiplied by x
Now we have our number : x = 3
