Answers
The answer is a rectangular prism
The boxes of Fred's Fudge, made of 2 triangles and 3 rectangles, are most likely shaped as triangular prisms.
Each box of Fred's Fudge is constructed from 2 triangles and 3 rectangles. The shape of each box can be determined by visualizing how the triangles and rectangles are assembled. In most cases, packaging that includes triangles would imply the presence of triangular prism shapes, where the triangles serve as the ends and the rectangles connect the corresponding sides of the triangles. Hence, it's reasonable to conclude that the shape of each box is likely a triangular prism.

Sabra joins a cooking club for $8.50 and pays $6.25 each month. She also joins a movie club for $12 and pays $3.75 each month. Write an expression that represents the total amount of money Sabra spends on both clubs after m months. Then enter the simplified expression in the boxes.
Answers
To start we can write the following two expressions for her expenses.
8.5 + 62.5m and 12 + 3.75m
Then, adding the two expressions together will give us a combined expression of: 10m + 20.5
Total amount of money Sabra spends on both clubs = 20.50 + 10m
Amount paid to join the cooking club = $8.50
Monthly payment at the cooking club = $6.25
Payment for m months at the cooking club = 6.25m
Total money paid at the cooking club = 8.50 + 6.25m
Amount paid to join the movie club = $12
Monthly payment at the movie club = $3.75
Payment for m months at the movie club = 3.75m
Total money paid at the movie club = 12 + 3.75m
Total amount of money Sabra spends on both clubs = Total money paid at the cooking club + Total money paid at the movie club
Total amount of money Sabra spends on both clubs = 8.50 + 6.25m + 12 + 3.75m
Total amount of money Sabra spends on both clubs = 20.50 + 10m

You have a 64 foot of fencing. What are the dimensions of the rectangle of the greatest area you could enclose?
Answers
Let one side have length x.
The opposite side also has length x.
The lengths of these two sides add to 2x.
The lengths of all 4 sides add to 64, so the lengths of the other 2 sides
add up to 64 - 2x. Each side measures 32 - x.
The rectangle has sides of length x and 32 - x.
The area of the rectangle is
A = LW
A = x(32 - x)
A = 32x - x^2
y = 32x - x^2 is a parabola that opens downward.
The maximum value of the parabola is the vertex on top.
32x - x^2 = 0
(32 - x)x = 0
32 - x = 0 or x = 0
x = 32 or x = 0
Since the parabola is symmetric with respect to the vertical axis, the vertex has x-coordinate 16.
At x = 16, you get maximum area.
Two opposite sides measure 16 ft each.
32 - x = 32 - 16 = 16
The other two opposite sides also measure 16 ft.
Since all sides turned out to have length 16 ft, the rectangle is a square.
Answer: The maximum area is enclosed by a square with side 16 ft.

First, we need to find the common denominator.
6 × 2 = 12
4 × 3 = 12
Our least common denominator is 12.
Now, we convert the fractions and add.
7 1/6 = 7 2/12
5 1/4 = 5 3/12
5 1/6 = 5 2/12
7 2/12 + 5 3/12 + 5 2/12 = 17 7/12

The expression 12g12g12, g gives the number of kilometers a car can travel using ggg liters of gasoline. How far can this car travel on 5 \dfrac125 2 1 5, start fraction, 1, divided by, 2, end fraction liters of gasoline?
Answers
The car can travel 66 miles using 5.5 liters of gasoline
Explanation:
We are given that:
The expression 12*g is used to evaluate the number of miles the car can travel using g liters of gasoline.
Therefore:
miles = 12*g
Now, we are given that the liters of gasoline = 5[tex] \frac{1}{2} [/tex] = 5.5 liters.
To get the number of miles, all we have to do is substitute with the given liters in the above expression as follows:
miles = 12*g
miles = 12 * 5.5
miles = 66 miles

The sum of two numbers is 76. The first number is 4 more than twice the other. How much is the first number?
Answers
Since their sum is 76, then x+y=76.
Since x is 4 more than twice y, then x=4+2y.
Now, since you have a definition for x (x=4+2y), you can substitute that equation in for x in the first equation.
This gets you (4+2y)+y=76.
Now, simplifying that out, you get the solution for y: y=24. Since you know what y is, you can substitute that in for y in the first equation and find x:
x+24=76
x=76-24
x=52

y = 3x - 8
Explanation:
The equation in slope-intercept form is:
y = mx + c
where:
m is the slope
c is the y-intercept
We are given that the slope = 3
Therefore, the equation becomes:
y = 3x + c
Now, we need to get the value of c. We are given that the point (6,10) belongs to the line. Therefore, we will substitute with this point in the equation of the line and solve for c as follows:
y = 3x + c
10 = 3(6) + c
10 = 18 + c
c = 10 - 18
c = -8
Based on the above, the equation of the line is:
y = 3x - 8

Last year Anthony earned $24,000. After a brief lay-off this year, Anthony's income is $18,500.
What I am basically trying to find is the Percent Of Change and I have to state whether or not the change is an increase or a decrease.
Answers
Final answer:
Calculate the percentage change in income, find a decrease of 22.92% from last year to this year.
Explanation:
Given:
Original income = $24,000
Current income = $18,500
Step 1: Calculate the change in income:
Change in income = New income - Original income = $18,500 - $24,000 = -$5,500
Step 2: Calculate the percentage change in income:
Percentage change = [(Change in income) / (Original income)] x 100
= [(-$5,500) / ($24,000)] x 100
= -22.92%
Step 3: Interpretation:
The percentage change is -22.92%, indicating a decrease in income by 22.92%.
The weight of a person on or above the surface of the earth varies inversely as the square of the distance the person is from the center of the earth. A particular person weighs 192 pounds on the surface of the earth and the radius of the earth is 3900 miles. Determine the equation that relates weight, W, to the distance from the center of the earth, d, for this person.
Answer choices on picture.
Answers
Weight = 192 pounds
Radius of the earth = 3900 miles
Let's introduce the constant, k
192 = [tex] \frac{k}{3900 ^{2} } [/tex]
k = 192 * 3900²
k = 192 * 15,210,000
k = 2,290,320,000
Putting the constant k back into the equation, W = [tex] \frac{k}{d ^{2} } [/tex]
W = [tex] \frac{2,290,320,000}{d ^{2} } [/tex]
(OPTION D)
The distance the person is from the center of the earth: d
W=K/d^2
W=192 pounds, d=R: Radius of the earth=3900 miles
Replacing in the equation above:
192=K/3900^2
Solving for K:
192=K/15,210,000
192*15,210,000=K
2,920,320,000=K
K=2,920,320,000
Then the equation is:
W=K/d^2 and K=2,920,320,000
W=2,920,320,000/d^2
Answer: Option d. W=2,920,320,000/d^2
James surveyed people at school and asked whether they bring their lunch to school or buy their lunch at school more often. The results are shown below.
Bring lunch: 46 males, 254 females
Buy lunch: 176 males, 264 females
The events "male” and "buys lunch” are not independent because
P(buys lunch | male) = P(male) = 0.4.
P(male | buys lunch) = P(male) = 0.3.
P(buys lunch | male) = 0.3 and P(male) = 0.4.
P(male | buys lunch) = 0.4 and P(male) = 0.3.
Answers
254 + 364 = 518
Which is total of 740 people.
The probability of being male is 0.3
46 + 254 = 300 that bring lunch
176 + 264 = 440 that buy their lunch
P(male | buy lunch ) = 0.4
Answer D
The events "male” and "buys lunch” are not independent because
P(buys lunch | male) = 0.3 and P(male) = 0.4.
Option C is the correct answer.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
We are given that,
P(buys lunch | male) = 0.3 (the probability that a male student buys lunch)
P(male) = 0.4 (the probability that a student is a male).
These values suggest that there is a dependence between the two events.
The probability of buying lunch at school may be different for males and females.
The conditional probability P (buys lunch | male) is not equal to the marginal probability P(buys lunch) if the events "male" and "buys lunch" are dependent.
To confirm this,
We would need to calculate the conditional probability
P(buys lunch | female) (the probability that a female student buys lunch).
If this probability is different from 0.3 (the probability for males), then the events "male" and "buys lunch" are dependent.
Therefore,
The events "male” and "buys lunch” are not independent because
P(buys lunch | male) = 0.3 and P(male) = 0.4.
