A recipe uses 4 cups of milk to make 8 servings. If the same amount of milk is used
for each serving, how many servings can be made from one pint?
1 gallon 4 quarts
1
quart
2 pints
1 pint = 2 cups
1 cup = 8 fluid ounces
Before you try that problem, answer the question below.
How many cups will you need to find the number of
servings for?
Answer: 4 servings
4 cups of milk = 8 servings
2 cups of milk = 4 servings
I divided both sides by 2 to change "4 cups milk" into "2 cups milk".
The reason why I want 2 cups of milk is because the chart you're given shows 1 pint is 2 cups.
Therefore, 1 pint of milk will get you 4 servings.

In a survey, 9 out of 10 dentists recommend PurWhite toothpaste for their patients. If 80 dentists were surveyed, how many doctors recommend PurWhite toothpaste?
Answer:
72 dentists
Step-by-step explanation:
In this case, we can multiply 80 by 9/10 or .9 to get our answer.
If we were to multiply by 9/10 it would look like this:
[tex]80 * \frac{9}{10} \\\frac{720}{10} = 72[/tex]
But, if we were to multiply by .90 (remember that 9/10 = .9) it would look like this:
[tex]80(.90) = 72[/tex]
Therefore, if 9 out of 10 dentists recommended PurWhite toothpaste and 80 were surveyed then 72 out of the 80 would have recommended it.
I hope this helps!!

Tori bought 24 candy bars for 69 cents each. She used partial products to find the total cost in cents. Which are NOT possible partial products for 24 × 69? Choose all that apply. A. 24 B. 36 C. 180 D. 240 E. 1,656
Answer:
B. 36 C. 180 D. 240 E. 1,656
Step-by-step explanation:
Partial product is the multiplication of individual digit of a number in turn with each digit of the others where each digit maintains its place.
Using distributive property to multiply 24 × 69 to determine our partial products:
i.e.
24 × 69 = 24 × (60 + 9)
= (24 × 60) + (24 × 9)
= 60 (20 + 4) + 9(20 + 4)
So; we can have:
= (60 × 20) + (60 × 4) + (9 × 20) + (9 × 4)
= 1200 + 240 + 180 + 36
= 1656

Answer:
question 1 asks about the volume and question 2 asks about the surface area.. I can't see all of question 3... soo I'll give you the first two only
Step-by-step explanation:
this seems like it would be easier to figure out.. if we did the volume of the block that would fit around the odd shape of the foam soooo
the block would be 10 inches tall by 36 inches long by 20 inches in depth
use a calculator.. 10 x 36 x 20 = 7200 [tex]inches^{3}[/tex] is the volume... of just a block that would fit perfectly over that foam structure.. now subtract the two pieces that are not part of the block.. the long rectangle and the triangle off the end.
the first one to subtract is a block that is 8 x 5 x 20= 800
the second piece to subtract is the triagle block that is 18 x 8 so the formula for the area of a triangle is 1/2 base * height = 1/2 (18*8)= 72
7200-800-72=[tex]inches^{3}[/tex] is the total volume of the shape
the surface area is just add up each flat area of the shape
side = 36x10 - 8x5 - 1/2(8x20)
side = 240
5x20 + 8x20 + 5x20 + 10x20 + 20x20 + 2x20 +36x20 + 2(side)= 2200 [tex]inches^{2}[/tex]

d) The difference between the annual and semi-annual compound interest on
of money is Rs 482 at the rate of 20 % per annum for 2 years. Find the sum
Answer:
Rs 20000
Step-by-step explanation:
Let the sum is x.
The rate of interest, r=20%=0.2
Time, t=2 years.
Total amount after t years, [tex]A= x \left(1+\frac{r}{n}\right)^{tn}[/tex]
The value of n when compounded annually, n=1
So, the total amount,
[tex]A_1=x \left(1+\frac{0.2}{1}\right)^{2\times 1}=x(1.2)^2[/tex]
The compound interest when compounded annually,
[tex]I_1 =x(1.2)^2-x[/tex]
The value of n when compounded semi-annually, n=2
So, the total amount, [tex]A_2 = x \left(1+\frac{0.2}{2}\right)^{2\times 2}=x(1.1)^4[/tex]
The compound interest when compounded semi-annually,
[tex]I_2 =x(1.1)^4-x[/tex]
As the difference between the annual and semi-annual compound interest on x amount of money is Rs 482, so
[tex]I_2-I_1=482 \\\\(x(1.1)^4-x)-(x(1.2)^2-x)=482 \\\\x(1.1)^4-x(1.2)^2=482 \\\\x(1.1^4 - 1.2^2) = 482 \\\\x(0.0241) = 482 \\\\x=482/0.0241 \\\\[/tex]
x=20000
Hence, the sum is Rs 20000.
Use the algebraic expressions for the length and width of Marlene's living room found in the
23.
diagram and the value of x found in Question 21C.
A. Find the actual length and width of her living room.
B
Find the actual area of Marlene's living room. Use actual dimensions.
Answer:
The area of Marlien's living room is 420 square ft
Step-by-step explanation:
Before calculating the real dimensions of Marlien's living room, we must find the value of x.
Given the total shape of the house is a rectangle, then both widths must be equal and both lengths must be equal.
The widths are already written width identical expressions x-2+x, but the lengths are given as different functions of x. Equating both expressions, we have:
[tex]2x-10+x-2+\frac{1}{2}x-4+x-2=2x+2+\frac{1}{2}x-4+x-2[/tex]
Simplifying:
-10 + x - 2 = 2
x = 10 + 2 + 2
x = 14
Since x=14 feet, the dimensions of Marlien's living room are
width=x=14 feet
length=2x+2=30 feet
Thus the area is:
A = 14*30 = 420 square ft
The area of Marlien's living room is 420 square ft

Objective: Solve systems of equations with three variables using addition/elimination.
Solving systems of equations with 3 variables is very similar to how we solve systems with two variables. When we had two variables we reduced the system down
to one with only one variable (by substitution or addition). With three variables
we will reduce the system down to one with two variables (usually by addition),
which we can then solve by either addition or substitution.
To reduce from three variables down to two it is very important to keep the work
organized. We will use addition with two equations to eliminate one variable.
This new equation we will call (A). Then we will use a different pair of equations
and use addition to eliminate the same variable. This second new equation we
will call (B). Once we have done this we will have two equations (A) and (B)
with the same two variables that we can solve using either method. This is shown
in the following examples.
Example 1.
3x +2y − z = − 1
− 2x − 2y +3z = 5 We will eliminate y using two different pairs of equations
5x +2y − z = 3

3x +2y − z = − 1 Using the first two equations,
− 2x − 2y +3z = 5 Add the first two equations
(A) x +2z = 4 This is equation (A), our first equation
− 2x − 2y +3z = 5 Using the second two equations
5x +2y − z = 3 Add the second two equations
(B) 3x +2z = 8 This is equation (B), our second equation
(A) x +2z = 4 Using (A) and (B) we will solve this system.
(B) 3x +2z = 8 We will solve by addition
− 1(x +2z) =(4)( − 1) Multiply (A) by − 1
− x − 2z = − 4
− x − 2z = − 4 Add to the second equation, unchanged
3x +2z = 8
2x = 4 Solve, divide by 2
2 2
x = 2 We now have x! Plug this into either(A) or(B)
(2) +2z = 4 We plug it into (A),solve this equation,subtract 2
− 2 − 2
2z = 2 Divide by 2
2 2
z = 1 We now have z! Plug this and x into any original equation
3(2) +2y − (1)= − 1 We use the first, multiply 3(2) =6 and combine with − 1
2y + 5= − 1 Solve,subtract 5
− 5 − 5
2y = − 6 Divide by 2
2 2
y = − 3 We now have y!
(2, − 3, 1) Our Solution
As we are solving for x, y, and z we will have an ordered triplet (x, y, z)

Answer:
343 cubic feet
Step-by-step explanation:
A company rents a storage unit. The unit is in the shape of a cube.
The formula V=s^3 can be used to find the volume of a cube.
Using the formula, determine the volume of the storage unit if the side length (s) is 7 feet.
From the above question
Side length (s) = 7 feet
Formula for the cube = V = s³
Volume of the cube(storage unit) = (7 feet)³

Andrew needs a ladder to hang holiday lights. His house is 24 feet tall and he has a flower bed that extends 4 feet out from the side of the house. How long of a ladder will he need to reach the top and be out of the flower bed?
Answer:
24.33 feet
Step-by-step explanation:
The flower bed, the ladder and the house form a right angled triangle where the length of the ladder is the hypotenuse side.
Let L = length of ladder, H = height of house = 24 feet and l = length of flower bed = 4 feet.
Using Pythagoras' theorem,
L² = H² + l²
So, L = √(H² + l²)
substituting the values of the variables, we have
L = √[(24 ft)² + (4 ft)²]
L = √[576 ft² + 16 ft²]
L = √[592 ft²]
L = 24.33 ft
The ladder must be at least 24.33 feet long to reach the top and be out of the flower bed
We may conclude that (a) events A and B are independent. (b) events A and B are mutually exclusive. (c) either A or B always occurs. (d) events A and B are complementary. (e) none of the above is correct.
Answer:
The answer is below
Step-by-step explanation:
The question is not complete. But I would show you how to solve the problem.
Two events A and B are said to be independent if the occurrence of event A does not affect the occurrence of event B and vice versa. P(A and B) = P(A) * P(B).
Two events A and B are said to be mutually exclusive if event A and event B cannot occur at the same time. P(A and B) = 0.
Two events A and B are said to be complementary when event A occurs if and only if event B does not occur and vice versa.
Enter the value of p so the expression 4(n+7) is equivalent to (n+p)4.
Answer:
p=7
Step-by-step explanation
both n and 4 are in both so p will have to be the same thing as 7 in order to be equal
The value of p that makes the expressions 4(n+7) and (n+p)4 equivalent is p = 7.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To make the expressions 4(n+7) and (n+p)4 equivalent, we need to distribute the 4 in the second expression, which gives us:
(n+p)4 = 4n + 4p
Now we can set this expression equal to 4(n+7) and solve for p:
4n + 4p = 4(n+7)
Simplifying both sides:
4n + 4p = 4n + 28
Subtracting 4n from both sides:
4p = 28
Dividing both sides by 4:
p = 7
Therefore,
The value of p that makes the expressions 4(n+7) and (n+p)4 equivalent is p = 7.

A rectangle has length 4 inches and width 2 inches. If the length and width of the rectangle are each reduced by 50 percent, by what percent will the area of the rectangle be reduced?
Answer: 25%
Step-by-step explanation:
Given: A rectangle has length 4 inches and width 2 inches.
Area = Length x width
= 4 inches x 2 inches
= 8 square inches
If length is reduced by 50% , then length [tex]=0.5\times4=2\text{ inches}[/tex]
If width is reduced by 50% , then length [tex]=0.5\times2=1\text{ inch}[/tex]
Reduced area = (reduced length) x (reduced width)
= 2 inches x 1 inch
= 2 square inches
The percentage of the area of the rectangle be reduced :-
[tex]\dfrac{\text{Reduced area}}{\text{Original area}}\times100 \\\\=\dfrac{2}{8}\times100\% \\\\=25\%[/tex]
Hence, the percent of the area of the rectangle be reduced = 25%
