50 pizzas can be sold in 10 hours, according to this equation p = 5h.
What is equation ?In mathematics, an equation is a statement that asserts the equality of two expressions. An equation typically consists of two expressions separated by an equal sign (=). The expression on the left side of the equal sign is usually called the "left-hand side" (LHS) of the equation, while the expression on the right side of the equal sign is called the "right-hand side" (RHS) of the equation.
Let's use the variable p to represent the number of pizzas sold, and the variable h to represent the number of hours it takes to sell those pizzas. We can use the formula for finding the rate of sales (also known as the unit rate) to write an equation that represents the situation:
rate = amount of sales ÷ time
In this case, we know that 35 pizzas are sold in 7 hours. So, the rate of sales is:
rate = 35 pizzas ÷ 7 hours
Simplifying this expression, we get:
rate = 5 pizzas per hour
Therefore, the equation that represents the situation is:
p = 5h
This equation tells us that the number of pizzas sold (p) is equal to 5 times the number of hours it takes to sell those pizzas (h). For example, if we want to know how many pizzas can be sold in 10 hours, we can plug in h = 10 and solve for p:
p = 5h
p = 5(10)
p = 50
Therefore, 50 pizzas can be sold in 10 hours, according to this equation p = 5h

5. Martin is a telemarketer and receives $75 every day he works. He make a baseline of 35 calls (c) every hour. For every call he makes over 35 in one hour, Martin receives a bonus of $5.50 per call. Martin works for 4 hours every day and makes the same number of calls every hour. Write a function to express the total amount of money Martin will make as a function of the number of calls he makes. If Martin makes a total of 45 calls every hour, how much money will Martin make for the day?
Answer: The function to express the total amount of money Martin will make as a function of the number of calls he makes is:
Total Money = (Number of hours worked x Base pay per hour) + (Bonus pay per hour x Number of bonus calls)
Where:
Number of hours worked = 4
Base pay per hour = $75 / 4 = $18.75 (since he works for 4 hours every day and receives $75)
Bonus pay per hour = ($5.50 x (Number of bonus calls)) / 4 (since he works for 4 hours every day and receives a bonus of $5.50 per call over 35 in one hour, which is equivalent to $5.50 / 4 per call)
Number of bonus calls = (Total calls - (Number of hours worked x Baseline calls per hour))
Using this formula, we can calculate how much money Martin will make for the day if he makes a total of 45 calls every hour:
Number of bonus calls = (45 - (4 x 35)) = 5
Bonus pay per hour = ($5.50 x 5) / 4 = $6.875
Total Money = (4 x $18.75) + (4 x $6.875) = $75 + $27.50 = $102.50
Therefore, if Martin makes a total of 45 calls every hour, he will make $102.50 for the day.

Benjamin's math teacher finds that there's roughly a linear relationship between the amount of time students spend on their homework and their weekly quiz scores. This relationship can be represented by the equation y=8x+57 where y represents the expected quiz score and x represents hours spent on homework that week. What is the meaning of the x-value when y = 98?
When the quiz score is expected to be 98, the corresponding x-value, which represents the number of hours spent on homework, is approximately 5.125 hours.
What is the linear equation in two variables?
A linear equation in two variables is an equation of the form:
ax + by = c
where x and y are variables, a, b, and c are constants, and a and b are not both zero. The graph of a linear equation in two variables is a straight line, and any point on the line satisfies the equation.
The given equation is:
y = 8x + 57
where y is the quiz score and x is the hours spent on homework.
To find the meaning of the x-value when y = 98, we can substitute y = 98 into the equation and solve for x:
98 = 8x + 57
Subtracting 57 from both sides, we get:
41 = 8x
Dividing both sides by 8, we get:
x = 5.125
when the quiz score is expected to be 98, the corresponding x-value, which represents the number of hours spent on homework, is approximately 5.125 hours. This suggests that students who spend around 5 hours and 7.5 minutes on homework per week can expect to score around 98 on their weekly quiz.
Therefore, when the quiz score is expected to be 98, the corresponding x-value, which represents the number of hours spent on homework, is approximately 5.125 hours.

The length of an arc RV of circle M with a radius of 6 units is 3pi/2 units. What is the approximate measure of angle RMV?
the options are
A- 15
B- 45
C-66
D-231
Answer:
The formula for the length of an arc of a circle is given by:
length of arc = (central angle/360) x 2πr
where r is the radius of the circle and the central angle is measured in degrees.
In this problem, we know the length of arc RV is 3π/2 units and the radius of circle M is 6 units. Therefore, we can solve for the central angle using the formula above:
3π/2 = (central angle/360) x 2π(6)
3π/2 = (central angle/180) x π x 6
3/2 = (central angle/180) x 6
central angle = (3/2) x (180/6) = 45 degrees
So the approximate measure of angle RMV is 45 degrees, which corresponds to option B.
Find the total surface area of a large round bowl (hollow hemisphere) with outer radius of 12 cm and thickness of 1 cm. 1cm 12cm
The total surface area of the hollow hemisphere is 1736.4 cm²
The total surface area of a large round bowl (hollow hemisphere) can be calculated by finding the surface area of the outer hemisphere and the surface area of the inner hemisphere and area of the ring and adding them together.
The formula for the surface area of a hemisphere is 2πr^2, where r is the radius of the hemisphere.
The outer radius of the bowl is 12 cm, so the surface area of the outer hemisphere is:
Surface area of outer hemisphere = 2π(12)^2 = 2π(144) = 288π
The inner radius of the bowl is the outer radius minus the thickness, which is 12 - 1 = 11 cm. So the surface area of the inner hemisphere is:
Surface area of inner hemisphere = 2π(11)^2 = 2π(121) = 242π
area of the concentric circle joining the outer surface and inner surface is π(12²-11²)= 23π
The total surface area of the bowl is the sum of the surface area of the outer hemisphere and the surface area of the inner hemisphere:
Total surface area = 288π + 242π + 23π = 553π
So the total surface area of the bowl is 530π cm^2.
then we can use the approximation π ≈ 3.14 to find the total surface area:
Total surface area ≈ 553*(3.14) ≈ 1736.4 cm^2
So the total surface area of the bowl is approximately 1736.4 cm^2.

Natasha wants to average at least 90% in math class. Her test scores so far are 94%, 89%,88%,92%, and 85% What score does she need to earn on her next test to reach her goal
Answer:
Let x be the score Natasha needs to earn on her next test to reach an average of 90%.
To find x, we can use the formula for the average:
average = (sum of scores) / (number of scores)
We know that Natasha has taken 5 tests so far, with scores of 94%, 89%, 88%, 92%, and 85%. We can plug these values into the formula and solve for x:
90% = (94% + 89% + 88% + 92% + 85% + x) / 6
Multiplying both sides by 6, we get:
540% = 448% + x
Subtracting 448% from both sides, we get:
92% = x
Therefore, Natasha needs to earn a score of at least 92% on her next test to reach an average of 90%.

Answer:
a = 3, b = 9
Step-by-step explanation:
What is a scale factor?A scale factor is the number that you multiply each side of a shape to enlarge it. A scale factor of 3 means that each side of the new shape is three times the size of the original.
If the new shape is 3 times the size of the original, then we can take the side lengths (3 and 1) and multiply them by 3.
3 × 1 = 3 (side a)3 × 3 = 9 (side b)Therefore, the length of a is 3, whereas the length of b is 9.
In 2010, bachelor's degrees conferred by colleges and universities in the United States were 1.2 million. In 2020, the number of bachelor's degrees awarded was 1.7 million.

(b) If the trend continues, estimate the number of bachelor's degrees to be awarded in 2023.
(c) Write a practical sentence expressing how the number of bachelor's degrees awarded changes yearly.
(d) Graph the number of bachelor's degree line over the time period stated in (a)
The equation that describe the number N bachelor's degrees awarded is N = 0.05t + 1.2 (a). The estimated number of bachelor's degrees to be awarded in 2023 is 1.85 million (b).
The practical sentence is "The number of bachelor's degrees awarded increases by 0.05 million, or 50,000, each year." (c). The graph, see the attachment.
The Explanation to Each Answer(a) To find the equation describing the number N of bachelor's degrees awarded t years after 2010, we can use the formula for a linear equation: N = mt + b, where m is the slope and b is the y-intercept.
We can find the slope by using the formula m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line. In this case, the two points are (2010, 1.2 million) and (2020, 1.7 million).
The y-intercept is the value of N when t = 0, which is the number of bachelor's degrees awarded in 2010, or 1.2 million. So the equation is:
N = 0.05t + 1.2(b) To estimate the number of bachelor's degrees to be awarded in 2023, we can plug in the value of t = 2023 - 2010 = 13 into the equation:
N = 0.05(13) + 1.2N = 0.65 + 1.2N = 1.85 millionSo the estimated number of bachelor's degrees to be awarded in 2023 is 1.85 million.
(c) A practical sentence expressing how the number of bachelor's degrees awarded changes yearly is: "The number of bachelor's degrees awarded increases by 0.05 million, or 50,000, each year."
(d) To graph the number of bachelor's degree line over the time period stated in (a), we can plot the two points (2010, 1.2) and (2020, 1.7) and draw a line through them.

The surface area of the cone is given as 3750 square units. The formula for the surface area of a cone is:
Surface Area of Cone = πr(r + l),
where "l" is the slant height of the cone. Since the slant height is not given in the problem, we need to express "l" in terms of "r" and "h" using the Pythagorean theorem:
l² = r² + h²
l² = (3/4)² h² + h²
l² = (9/16)h² + h²
l² = (25/16)h²
l = (5/4)h
Substituting this expression for "l" and the expression for "r" from equation (1) into the surface area formula, we get:
3750 = πr(r + l)
3750 = π[(3/4)h] [(3/4)h + (5/4)h]
3750 = π (9/16 + 15/16) h²
3750 = π (24/16) h²
3750 = (3/2) π h²
h² = (2500/3π)
h ≈ 28.867
Substituting this value of "h" into equation (1), we get:
r = (3/4)h
r ≈ 21.65

Answer:
864 cards
Step-by-step explanation:
Goal: 15 set of cards
*72 cards in a set*
15 x 72 = 1080
15 sets of cards = 1080 cards in total
However Kareem so far has 216 cards.
To find out how much more cards Kareem need to reach his goal, you do the following:
1080 - 216 = 864
Kareem needs 864 more cards to reach his goal.

Question 11
Which values in the data set are outliers? Show all work.
72, 81, 82, 83, 83, 85, 100, 54, 75, 81, 83
List the following (and show work if needed): Q1, Median, Q3, Lower Fence, Upper Fence, and Outliers
The dataset's median, which has a value of 82 and a total of 11 values, is the sixth figure.
what is median ?When a dataset is ordered from smallest to largest, the median, a measure of central tendency, shows the middle value of the dataset. It is frequently used as a more reliable substitute for the mean, which can be vulnerable to anomalies in the data with extremely high or low values. We must first sort the numbers in a dataset from smallest to largest before we can determine the median. The median is just the middle value when the dataset has an odd number of numbers. For instance, the median, or middle number, in the dataset "2, 5, 7, 10, 12" is 7.
given
Values that are noticeably higher or lower than the remainder of the dataset are found using the fences.
Step 1: Sort the information by size, starting from the smallest:
[tex]54, 72, 75, 81, 81, 82, 83, 83, 83, 85, 100[/tex]
Step 2: Calculate the middle
The dataset's median represents its middle number. The median is the sixth number in the dataset, which contains 11 values total:
Average: 82
Step 3: Determine the first and third quartiles (Q1 and Q3, respectively):
The medians for the dataset's lower and upper halves are Q1 for the lower part and Q3 for the upper. We don't use the median value to determine Q1 and Q3 because the dataset has an odd amount of values.
54, 72, 75, 81, 81 in the bottom half.
Top half: 83, 83, 83, 83, 85, and 100
Q1 = 75 for the bottom half's median.
Q3 = 83 for the top half's median.
The dataset's median, which has a value of 82 and a total of 11 values, is the sixth figure.

Problem \# 6: Let R^4 have the Euclidean inner product. Find a unit vector with a positive first component that is orthogonal to all three of the following vectors. u = (1,-1, 7, 0) ; v=(8,1,0,1) ; w=(1,0,6,1)
Problem \#6: Enter your answer symbolically, as in these Enter the four components of your vector, separated with commas.
To find a unit vector with a positive first component that is orthogonal to all three of the given vectors, we need to find a vector x = (x1, x2, x3, x4) that satisfies the following equations:
= 0
= 0
= 0
This means that:
x1 - x2 + 7x3 = 0
8x1 + x2 + x4 = 0
x1 + 6x3 + x4 = 0
We can solve this system of equations to find x. One possible solution is x = (1, -1, 0, 1). However, this is not a unit vector, so we need to divide each component by the length of the vector to get a unit vector:
x = (1, -1, 0, 1) / ||(1, -1, 0, 1)|| = (1/sqrt(3), -1/sqrt(3), 0, 1/sqrt(3))
So, the unit vector with a positive first component that is orthogonal to all three of the given vectors is (1/sqrt(3), -1/sqrt(3), 0, 1/sqrt(3)).

Find the lateral area and total surface area of the rectangular prism. 12in, 7in, 5in
Answer:
The lateral area of the prism is 190 square inches and the total surface area is 358 square inches.
Step-by-step explanation:
To find the lateral area and total surface area of a rectangular prism, we need to use the following formulas:
Lateral Area = perimeter of the base x height
Total Surface Area = 2 x base area + lateral area
Where the base area is simply the product of the length and width of the rectangular prism.
Let's apply these formulas to the rectangular prism with dimensions 12in x 7in x 5in:
Lateral Area:
To find the perimeter of the base, we add up the lengths of all four sides of the rectangle:
Perimeter of the base = 2(length + width) = 2(12in + 7in) = 2(19in) = 38in
Now, we multiply the perimeter of the base by the height of the prism:
Lateral Area = 38in x 5in = 190in^2
Therefore, the lateral area of the rectangular prism is 190 square inches.
Total Surface Area:
To find the base area, we simply multiply the length and width of the rectangular prism:
Base Area = length x width = 12in x 7in = 84in^2
Now, we can use the formula for total surface area:
Total Surface Area = 2 x base area + lateral area
Total Surface Area = 2(84in^2) + 190in^2
Total Surface Area = 168in^2 + 190in^2
Total Surface Area = 358in^2
Therefore, the total surface area of the rectangular prism is 358 square inches.
So the lateral area of the prism is 190 square inches and the total surface area is 358 square inches.
