Step-by-step explanation:ddo the area with both triangles then multiply

Answer: 1020

Step-by-step explanation:

The following system of linear equations is shown in the graph.

y equals one fourth times x minus 1
x − 4y = 4

a coordinate plane with two lines that pass through the points 0 comma negative 1 and 4 comma 0

How many solutions does the system of linear equations have?

No solution
Infinitely many solutions
One solution at (4, 0)
One solution at (0, −1)

Answers

The system of linear equations is given as:

y = 1/4x - 1

x - 4y = 4

To find the solution, we can substitute y in the second equation with 1/4x - 1:

x - 4(1/4x - 1) = 4

x - x + 4 = 4

4 = 4

The equation 4 = 4 is always true, which means that the system of linear equations has infinitely many solutions.

Therefore, the answer is:

Infinitely many solutions.

Professional support careers help people involved in education and training systems with personal and family needs,  educational goals, mental health assistance, and career decision-making. They provide support and encouragement to students undergoing challenging experiences. Professional support career titles include counselors and Psychologists, among others.

Teachers and trainers offer instructions to students in the class or other conducive places. They help students complete their syllabus, learn the intended materials, acquire knowledge, and pass their examinations.

Both careers try to support student success; however, teaching and training careers involve direct instruction of students.

Obviously, if this doesn't apply to your question, you can use it as a guide. Just multiply how many things are together and you can get the number of possible outcomes.

Kylie brought 5 pears to soccer practice to share with her teammates. She cuts each pear into thirds. How many slices of pears does she have to share with her teammates? Which equations can you use to solve the problem? Select two equations.

A. 5 × 3 = 15

B. 1/5 × 1/3 = 1/15

C. 1/5 × 3 = 3/5

D. 5 ÷ 1/3 = 15

E. 1/3 ÷ 5 = 1/15

Answers

Answer:

A and D

Step-by-step explanation:

One pear is split into thirds. That means that one pear can become 3 slices. Because you have 5 pears, you have 15 slices. By multiplying 3 (slices) and 5 (pears), we receive the answer of 15 slices.

The answer is A and D.

Step-by-step explanation - Kylie brought 5 pears to practice. Because she cut each of them into thirds, this means that each pear equals 3 slices - therefore making the equation 5 x 3 = 15 and also making the equation 5 ÷ 1/3 because them two both equal 15.

A rectangular prism with dimensions 5 inches by 13 inches by 10 inches was cut to leave a piece as shown in the image. What is the volume of this piece? What is the volume of the other piece?



HELP

Answers

To find the volume of the piece that was cut out, you need to calculate the volume of the original rectangular prism and then subtract the volume of the remaining piece.

The volume of the original rectangular prism is given by:

V1 = length x width x height
= 5 inches x 13 inches x 10 inches
= 650 cubic inches

To find the volume of the remaining piece, you need to determine its dimensions. If you have an image or a description of the piece, you can use that information to calculate its volume. Once you have the volume of the remaining piece, you can subtract it from the volume of the original rectangular prism to get the volume of the piece that was cut out.

To find the volume of the other piece, you can subtract the volume of the piece that was cut out from the volume of the original rectangular prism:

V2 = V1 - V_cut_out

where V_cut_out is the volume of the piece that was cut out.

B) After five weeks of his earning, he has to pay 28% in taxes. How much were the
taxes? How much of his total pay does he have left after taxes? Show and explain all
of your work.


ANSWER BOTH QUESTIONS QUESTION A AND QUESTION B.

Answers

Answer: A) $333

B) $468

Step-by-step explanation:

A) First we multiply. 130x5=650 Now we know that we have to get $650 total in 5 weeks in order to get an average of $130 per week.

87+105+125=317

650-317=333

Necolai has to earn $333 the fifth week to achieve an average of $130 per week.

B) 28% of 650 = 182

Now subtract the taxes from his earnings. 650-182=468

Necolai has $468 of his total pay after taxes.

Question A:
To find how much Necolai has to earn in the fifth week to achieve an average of $130 per week, we have to use the concept of mean.

The average of five weeks' earnings should be $130. Therefore, the sum of his five-week earnings should be:

5 * 130 = 650

Necolai's total earnings for the first four weeks are:

87 + 105 + 125 + x (earning in the fifth week) = 317 + x

317 + x + y = 650

where y represents his earnings in the fifth week. Solving for y, we get:

y = 650 - 317 - x
y = 333 - x

So, Necolai has to earn $333 in the fifth week to achieve an average of $130 per week.

Question B:
After earning $87, $105, $125, and x dollars (from the third week), Necolai’s total earning are $317 + x. After 5 weeks, Necolai has to pay 28% in taxes, which means he gets to keep 72% of his earnings.

The taxes are calculated as:

Taxes = 0.28 * (317 + x)
Taxes = 88.76 + 0.28x

Therefore, the taxes he has to pay after five weeks are $88.76 + 0.28x.

The portion of his total earnings that he keeps after taxes is:

Total earnings - Taxes = (317 + x) - (88.76 + 0.28x)
Total earnings - Taxes = 228.24 + 0.72x

Therefore, after paying taxes, Necolai is left with $228.24 + 0.72x of his total earnings.

A photographer’s darkroom needs a new coat of black paint on all surfaces of the room, including the ceiling and the floor. The room is a cube with edge length 11
feet. How much surface area must be painted?

Answers

The surface area of a cube is given by the formula 6s^2, where s is the length of the edge. In this case, s = 11 feet, so the surface area of the cube is:

6s^2 = 6(11)^2 = 6(121) = 726 square feet

Since the room has six surfaces that need to be painted (four walls, one ceiling, and one floor), the total surface area that needs to be painted is:

6 x 726 = 4356 square feet

Therefore, the photographer's darkroom needs to have 4356 square feet of black paint applied to all of its surfaces.

726 I believe
