-Okay so, we know that The lateral surface area of a prism is the sum of the areas of its lateral faces. And The total surface area of a prism is the sum of the areas of its lateral faces and its two bases. Then Usually, if "right" or "oblique" is not mentioned, you can assume the prism is a right prism. The general formula for the lateral surface area of a right prism is  L.S.A.=ph  where p represents the perimeter of the base and h represents the height of the prism.

Answer:

2 1/2

Step-by-step explanation:

( 11 1/4 ) / ( 4 1/2 ) = 2 1/2

( 2 1/2 ) = 5/2

The width of the pan is 2.70 inches.

The volume of the pan is 409,024 inches³

A rectangular prism is a polyhedron with six faces and twelve edges. It is also known as a cuboid.

The width of the foil can be determined by dividing the area by the length.

Width = area / length

1114 / 412 = 2.70 inches

Volume of the pan =length x width x height

83 x 154 x 32 = 409,024 inches³

Step-by-step explanation:

The Ella works 16 hours after school and 8 hours before school.

What is an mathematical expression?

Expression in mathematics is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Here, it is given that :

Ella works two part-time jobs, one before school and one after school. Before school, she earns $11.25/hour, and after school "a" she earns $11..75/hour and She works twice as many hours after school that is :

a = 2b ......(1)

also, 11.25a + 11.75b = 278....(2)

now, solving for a and b :

11.25a + 11.75b = 278

11.25(2b) + 11.75b = 278

b = 278/34.25

b ≈ 8 hours

Now, the value of a will be 2b = 16 hours

Therefore, the Ella works 16 hours after school and 8 hours before school.

Answer:

the answer is 600mph

Step-by-step explanation:

because 1800miles/3 hours=600mph

Answer:

600 mph

Step-by-step explanation:

In order to find the answer you must solve using this formula:

S=D/T

Where S is speed, D is distance, and T is time

You have time and distance, so you have to plug those into the formula:

S=1800/3

Then all you have to do is divide 1800/3 and get 600 for speed.

The population of interest to the department of education will be all college students.

A population is a large group of individuals that have some common feature by the researcher's point of interest.

Here the Department of Education wishes to estimate the proportion of all college students who have a job off-campus.

Proportion: A proportion is an equation in which two ratios are set equal to each other. If there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls) 1 / 4 are boys and 3 / 4 are girls. 0.25 are boys (by dividing 1 by 4).

So , he needs data of all students to compute the exact proportion.

But instead of that he surveyed 1600 randomly selected students which determine the sample.

Sample just gives the estimate of the parameter.

Hence, the population of interest to the Department of education is " All college students" .

Answer:

16 and 64

Step-by-step explanation:

The geometric mean n of two numbers a and b can be given as;

√ab = n

In this question;

a = 16

b = ?

n = 32

So we have

16 * b = 32^2

b = 32^2/16

b = (32 * 32)/16

b = 2 * 32

b = 64

Answer:

The vertical line [tex]x = -2[/tex] is the axis of symmetry of [tex]y = -(x + 2)^{2} + 8[/tex].

Step-by-step explanation:

For the graph of a quadratic function, the axis of symmetry is the vertical line that goes through the vertex of this function.

In general, if the vertex of a quadratic function is at [tex](x_{0},\, y_{0})[/tex], the vertex form equation of this function would be [tex]y = a\, (x - x_{0})^{2} + y_{0}[/tex] for some non-zero constant [tex]a[/tex] ([tex]a \ne 0[/tex].)

Rewrite the quadratic equation in this question [tex]y = -(x + 2)^{2} + 8[/tex] to match the vertex form:

[tex]y = -(x + 2)^{2} + 8[/tex].

[tex]y = (-1)\, (x - (-2))^{2} + 8[/tex].

Thus:

Hence, the vertex of this parabola would be at [tex](-2,\, 8)[/tex].

Again, the axis of symmetry of this graph would be a vertical line that goes through this vertex. The [tex]x[/tex]-coordinate of this vertical line would be [tex](-2)[/tex]. The equation of this vertical line would be [tex]x = (-2)[/tex].

Hence, the axis of symmetry of this quadratic function would be [tex]x = (-2)[/tex].

Answer:

To get to system B the second equation in system A was replaced by the sum of that equation and the first equation multiplied by 4. The solution to system B is the same as the solution to system A.

Step-by-step explanation:

A system of equations and it’s solution are given below.

System A.

x-y=3

-2x+4y=-2

Solution: (5,2)

Complete the sentences to explain what steps were followed to option the system of equations below.

System B

x-y=3

2x=10

To get to system B the (first/second) equation in system A was replaced by the sum of that equation and the (first/second) equation multiplied by (4....2.....-3) . The solution to system B (is/ is not) the same as the solution to system A.

Solution:

To get system B:

First write the first equation in system A. x - y = 3

Multiply the second equation in system A by 4 and add to the first equation in system A to get:

2x = 10

x = 10/2 = 5

Put x = 5 in x - y = 3

5 - y = 3

y = 5 - 3 =2

The solution to system B is the sam as that of system A

To get to system B the second equation in system A was replaced by the sum of that equation and the first equation multiplied by 4. The solution to system B is the same as the solution to system A.

The expression that represents the perimeter of the rectangle is [tex]$\boxed{20c + 10}$[/tex] centimeters.

We are given that;

Width= (8c-5)(8c−5) centimeters

Length= (2c 10)(2c 10) centimeters

Now,

The perimeter of a rectangle is given by the formula:

P = 2l + 2w

where l is the length and w is the width.

[tex]$w = (8c-5)\ cm$[/tex]

and

[tex]$l = (2c+10)\ cm$[/tex]

Substituting these values into the formula for the perimeter, we get:

[tex]$P = 2l + 2w = 2(2c+10) + 2(8c-5) = 4c + 20 + 16c - 10 = \boxed{20c + 10}\ cm$[/tex]

Therefore, by rectangle the answer will be [tex]$\boxed{20c + 10}$[/tex].
