What is the cross-section of a cone that is perpendicular to the base? Rectangle that is perpendicular to the base? Cylinder that is parallel to the base? Triangular Prism that is parallel to the base? (urgent now please answer)

Answers

Answer:

1. Triangle or trapezoid.

2. A line

3. Circular

4. Triangular.

Step-by-step explanation:

1. The cross-section of a cone that is perpendicular to the base either of a shape of a triangle or a trapezoidal shape.

If we make the cross-section along the diameter of the base circle then the cross-section will be a triangle and otherwise, it will be of trapezoidal shape.

2. The cross-section of a rectangle that is perpendicular to the base is line only because a rectangle is a two-dimensional shape and if we cut it perpendicularly to the base it will give a line.

3. The cross-section of a cylinder that is parallel to the base is a circle only.

Because the shape of a cylinder is constantly circular along the vertical axis.

4. The cross-section of a triangular prism that is parallel to the base is a triangle only.

Because the shape of a triangular prism is constantly triangular along the vertical axis. (Answer)

I can do this with Emma and Jacob or shopping in the store they notice to Cashiers are applying the discounts differently the cashier on the left is taking 20% off the total bill then subtracting $10 the cashier on the right is subtracting 10 first and then taking the 20% off the total who's getting the better deal ​

Answers

Answer: the person on the left

Step-by-step explanation:

by taking 20% off of the total cost first they are getting the better deal.

The customer gets a better deal from the cashier on the left. Explanation on determining the better deal between two cashiers based on how they apply discounts.

To determine who is getting the better deal, let's compare the total bill after discounts for both cashiers:

Cashier on the left: 20% off, then subtract $10

Cashier on the right: Subtract $10 first, then 20% off

Example Calculation:

If the total bill is $100:
Left cashier: $100 - 20%($100) = $80, then $80 - $10 = $70
Right cashier: $100 - $10 = $90, then 20%($90) = $18, so $90 - $18 = $72

In this scenario, the customer gets a better deal from the cashier on the left.

What is algebra ?

Algebra is a branch of mathematics that deals with various symbols and the arithmetic operations such as division , multiplication , etc.

It is given that Karli and her friend can paint 6/7 of a picture in 3/14 of an hour.

Let's assume they can paint x number of pictures in a full hour.

So , the fraction by dividing 6/7 by 3/14 can be written equal to x .

i.e.,

[tex]\frac{6/7}{3/14}[/tex] = x

We need to do the cross product here :

[tex]\frac{3}{14}[/tex] × x = [tex]\frac{6}{7}[/tex]

or

x = ([tex]\frac{6}{7}[/tex]) ÷ ([tex]\frac{3}{14}[/tex])

We know that when dividing two fractions we need to change the division sign to multiplication sign by inverse the fraction value right to the division sign i.e.,

x = ([tex]\frac{6}{7}[/tex]) × ([tex]\frac{14}{3}[/tex])

x = 84 / 21

x = 4

Therefore , the number of pictures which Karli and her friend can paint in a full hour is equal to 4 pictures.

You and your friend are selling magazine subscriptions. You sell 8 fewer magazine subscriptions than your friend. Together you sell 42 magazine subscriptions. Write a system of linear equations that represents this situation.

The system of linear equations that represents this situation is:

x + y = 42

x - y = 8

Step-by-step explanation:

To solve the problem assume that

x represent the number of magazine subscriptions that your friend selly represents the number of magazine subscriptions that you sell

∵ Your friend sells x magazine subscriptions

∵ You sell y magazine subscriptions

∵ Together you sell 42 magazine subscriptions

x + y = 42 ⇒ (1)

∵ You sell 8 fewer magazine subscriptions than your friend

∵ Your friend sells x magazine subscriptions

∵ You sell y magazine subscriptions

- That means y = x - 8

∴ y = x - 8

- Add 8 for both sides

∴ 8 + y = x

- Subtract y from both sides

∴ 8 = x - y

- Switch the two sides

x - y = 8 ⇒ (2)

(-8)-(6+30i) Express your answer in the form (a+bi)

Answers

Answer:

-14 - 30 i

Step-by-step explanation:

We recall that when combining complex numbers, we need to combine the real parts among themselves to get the new real part, and the imaginary parts among themselves to get the imaginary part of the new complex that results from the operation.

In our case the firs complex number is "-8" which consists of strictly real part (with zero imaginary part). The second complex number is (6+30 i) which has real part = 6 and imaginary part = 30 i.

now we operate separately on the real parts and on the imaginary parts performing the requested subtraction:

Real part:  -8 - 6 = -14

Imaginary part: 0 i - 30 i = -30 i

Therefore the final complex number that results from this subtraction is: "-14 - 30 i"

the greatest of four consecutive even integers is 14 less than twice the smallest integer. what are the integers​

Answers

The four consecutive even integers are 20, 22, 24, 26

Solution:

Let the four consecutive even integers are a , a + 2, a + 4, a + 6

Let "a" be the smallest integer and "a + 6" be the largest integer

To find: the four consecutive even integers

Given that the greatest of four consecutive even integers is 14 less than twice the smallest integer

largest integer = twice the smallest integer - 14

a + 6 = 2(a) - 14

a + 6 = 2a - 14

a - 2a = -14 - 6

-a = -20

a = 20

Thus the four consecutive even integers are:

a = 20

a + 2 = 20 + 2 = 22

a + 4 = 20 + 4 = 24

a + 6 = 20 + 6 = 26

Thus the four consecutive even integers are 20, 22, 24, 26

When Julia is writing a first draft, there is 0.7 probability that there will be no spelling mistakes on a page. One day, Julia writes a first draft that is 4 pages long. Assuming that Julia is equally likely to have a spelling mistake on each of the 4 pages, what is the probability that she will have no spelling mistakes on at least one of them?

Answers

Answer:

The required probability is  given by, 0.9919.

Step-by-step explanation:

Let, X be the random variable denoting the no. of pages among those 4 pages which Julia writes where she makes no spelling mistake.

clearly,

X [tex]\sim[/tex] Binomial (4, 0.7)

So,      P(X = x) = [tex]^4C_{x} \times (0.7)^{x} \times (0.3)^{(4 - x)}[/tex]

                            [when  x = 0, 1, 2, 3, 4]

                         = 0 otherwise

According to the question, we are to find out  P(X ≥ 1) .

Now, P(X ≥ 1)

     = 1 - P(X = 0)

     = [tex] 1 - (^4C_{0} \times (0.7)^{0} \times (0.3)^{4})[/tex]

     = [tex] 1 - 0.0081[/tex]

     = 0.9919

So, the required probability is  given by, 0.9919

The probability that Julia will have no spelling mistakes on at least one of the pages is approximately 99.19%.

To determine the probability that Julia will have no spelling mistakes on at least one of the four pages she writes, we can first find the probability that she will make at least one spelling mistake on all four pages and then subtract this from 1.

The probability that there will be a spelling mistake on a page:

= 1 - 0.7 = 0.3.

Since the probability of a spelling mistake on each page is independent, we can multiply the probabilities for the four pages together.

The probability of at least one mistake on all four pages:

= 0.3 x 0.3 x 0.3 x 0.3 = 0.3⁴= 0.0081.

The probability that there will be no spelling mistakes on at least one page

= 1 - 0.0081 = 0.9919 or about 99.19%.

So, the probability is 99.19%.

Answers

Answer:

(a) The equation is [tex]7h-2=56[/tex].

(b) Trey gets approximately $8.29 for each hour of work.

Step-by-step explanation:

Given:

Number of hours Trey works = 7

Amount of money he put aside for mom = $2

Total Amount he keeps each day = $56

We need to find the amount he gets for each hour.

Let 'h'  represent the amount (in dollars) Trey gets paid each hour.

Solving for part (a).

We need to write the equation to find the amount he gets paid for each hour.

Now we can say that;

Total Amount he keeps each day is equal to Number of hours Trey works multiplied by the amount he gets paid for each hour minus Amount of money he put aside for mom.

framing in equation form we get;

[tex]7h-2=56[/tex]

Hence the equation is [tex]7h-2=56[/tex].

Solving for part (b).

we need to solve the above equation to find the amount he gets paid for each hour.

On solving the equation we get;

Adding both side by 2 we get

[tex]7h-2+2=56+2\\\\7h=58[/tex]

Now Dividing both side by 7 using Division Property we get;

[tex]\frac{7h}{7} = \frac{58}{7}\\\\h \approx \$8.29[/tex]

Hence Trey gets approximately $8.29 for each hour of work.

in a game of tug of war your team changes -1 3/10 feet in position every 10 seconds. What is your change in position after 30 seconds?

Answers

To calculate the change in position after 30 seconds, multiply the rate of change per 10 seconds, which is -1 3/10 feet, by the number of 10-second intervals in 30 seconds, resulting in a total change of -3 9/10 feet or -3.9 feet.

If your team changes its position by -1 3/10 feet every 10 seconds in a tug of war game, we need to find out the change in position after 30 seconds.

Since the change in position is consistent over time, we can calculate the total change by multiplying the rate of change per 10 seconds by the number of 10-second intervals in 30 seconds.

The number of 10-second intervals in 30 seconds is:

30 seconds / 10 seconds per interval = 3 intervals.

The total change in position is then:

-1 3/10 feet/change × 3 changes = (-1 × 3)+(3/10 × 3)

= -3 9/10 feet or -3.9 feet.

Your team's change in position after 30 seconds is -3 9/10 feet or -3.9 feet.

Consider the net of a triangular prism where each unit on the coordinate plane represents four feet. If a sheet of plywood measures 4 ft x 8 ft, how many sheets of plywood will a carpenter need to build the prism?
A) 2
B) 3
C) 4
D) 5

Answers

Answer:

2 sheets of plywood will be needed.

Step-by-step explanation:

See the attached diagram.

Each three square plywood has area 1 units by 3 units = 4 feet by 12 feet = 48 feet square.  {Since each unit on the coordinate plane represents four feet}

Now, the two triangular plywood has area half of a unit square area.

So, two triangular plywood has total area = 1 unit by 1 unit = 4 feet by 4 feet = 16 feet square.

Therefore, the total area of plywood required to make the triangular prism is (48 + 16) = 64 feet square.

Now, if a sheet of plywood measures 4 ft by 8 ft i.e. 32 feet square, then the carpenter will need [tex]\frac{64}{32} = 2[/tex] such sheets of plywood. (Answer)

OUTCOME 4: There is a 70% Chance that a student will pass a statistics course if I randomly choose a group of five students find the probability that exactly two will pass the course and explain how you derived your solutions

Answers

Answer:

The required probability is [tex]\frac{1323}{10000}[/tex]

Step-by-step explanation:

It is given that The chance, that a student will pass the statistic course is [tex]\frac{70}{100}[/tex]

Hence, The chance that a student will fail in the statistic course is [tex]\frac{100 - 30}{100} = \frac{30}{100}[/tex]

Any 2 students from the total of 5 students can be choosen in [tex]^{5}C_2 = \frac{5!}{3! \times2!} = 10[/tex] ways.

Hence, the probability will be [tex]10\times [\frac{70}{100}] ^{2} \times[\frac{30}{100} ]^{3} = \frac{49\times27}{10000} = \frac{1323}{10000}[/tex]

Final answer:

The probability that exactly two students will pass the statistics course is approximately 30.87%.

Explanation:

To find the probability that exactly two students will pass the statistics course, we can use the binomial probability formula. The formula is:

P(X = k) = C(n, k) * p^k * (1 - p)^(n - k)

In this case, n = 5 (number of students), k = 2 (number of students passing), and p = 0.7 (probability of passing).

Plugging in these values, we get:

P(X = 2) = C(5, 2) * 0.7^2 * (1 - 0.7)^(5 - 2)

Calculating, we find that P(X = 2) ≈ 0.3087, or approximately 30.87%.

Jackson is working two summer jobs, landscaping and clearing tables. He must work
no less than 14 hours altogether between both jobs in a given week. Write an
inequality that would represent the possible values for the number of hours
landscaping, l, and the number of hours clearing tables, c, that Jackson can work in a
given week.

Answers

Final answer:

The inequality l + c ≥ 14 accurately represents the minimum total hours Jackson must work in both his jobs, landscaping and clearing tables, in a week.

Explanation:

The subject of this question is Mathematics, more specifically it involves the topic of inequalities. The grade level of this question would be high school as it deals with algebraic concepts.

The inequality that represents the number of hours that Jackson can work in a given week in landscaping (l) and clearing tables (c) would be l + c ≥ 14. This inequality allows for the total number of hours worked to be equal to or more than 14, as stipulated in the conditions.

This represents the total amount of hours Jackson can work in both jobs simultaneously. This inequality is valid as long as he works at least 14 hours, in total, from both jobs.

Answer:

D) the system has no solution.

Step-by-step explanation:

A student is solving a system of equations by substitution and comes up with the solution -3=2.

So, the unknown variables are canceled out and there are only numbers in the equation but -3 ≠ 2.

If we assume that she solved the problem correctly, then there will be no solution for that system of equations because there is no variable remaining in the final equation to solve for. (Answer)
