Step-by-step explanation:

Volume of a rectangular prism is:

V = lwh

Given that l = 4½, w = 3½, and h = 6:

V = (4½)(3½)(6)

V = 94.5

The volume is 94½ cm³.

The formula for the volume of a rectangular prism is:

V = length x width x height

OR

V = l x w x h

You must plug in the values given in the equation

Hope this helps.

The range of the given set {19, 12, 13, 3, 0, 0, 0, 0, 0, 0, 2, 13} is 19, which is the difference between the largest (19) and smallest (0) values in the set.

The range of a set of numbers is the difference between the largest and smallest values in the set. To find the range of the given numbers {19, 12, 13, 3, 0, 0, 0, 0, 0, 0, 2, 13}, follow these steps

Step 1: Arrange the numbers in ascending order: {0, 0, 0, 0, 0, 0, 2, 3, 12, 13, 13, 19}.

Step 2: Find the smallest value: 0.

Step 3: Find the largest value: 19.

Step 4: Calculate the range: Largest value - Smallest value = 19 - 0 = 19.

Answer:

O.118 seconds will be taken for a radio signal to travel from a satellite to the surface of earth.

Step-by-step explanation:

We are given Speed = 3.00 · 10^8 meters per second.

And Distance = 3.54.10^7 metwers

We need to find time.

We know that,

Distance = Speed * Time

3.54.10^7 = 3.00 · 10^8 * Time

Time = 3.54.10^7 / 3.00 · 10^8

Time = 1.18 X 10^7-8

Time = 1.18 x 10^-1

Time = 0.118 seconds.

So, O.118 seconds will be taken for a radio signal to travel from a satellite to the surface of earth.

Answer:

x = 0, y = 7

Step-by-step explanation:

Solving a system of equations using substitution requires one side to be equal to a variable present in the equation, in this case x or y. We should simplify the equation using elimination before substituting to reduce the chance of error.

In order to use the elimination method, you have to create variables that have the same coefficient—then you can eliminate them. These equations arew already aligned for us.

                  3x - 10y=-70

             -   4x +9y = 63

                  -x + y = 7

Now, for substitution, the equation must be set to a variable.

                  -x + y = 7

                  y = x + 7

Next, plug the equation in where applicable in another equation.

                  4x +9(x + 7) = 63

                  4x + 9x + 63 = 63

                  13x = 0

                  x = 0

The final step of substitution is to plug the known variable into an equation to find the other variable.

                  3(0) - 10y=-70

                  0 - 10y = -70

                  10y = 70

                  y = 7

I guarantee you this answer is correct, I worked it out using other methods and graphing prior to submitting this answer.

Answer:

x = 0 , y = 7

Step-by-step explanation:

Step-by-step explanation:

Just find the *median* of each coordinate.

In this Multiplication in Algebra question, The expression '80 (1/4) x' is equivalent to '20x'. When the constant 80 multiplies with the fraction 1/4, the product then multiplies with the variable 'x' resulting in a simplified expression '20x'.

The given mathematical expression 80 (1/4) x can be simplified using the rules of multiplication in algebra.

Here the number 80 multiplies with the fraction 1/4 and then by the variable 'x'.

To carry out this operation, first multiply 80 by 1/4 which equals to 20, and then multiply this by 'x', so your final result would be 20x. Hence, the expression 80 (1/4) x is equivalent to 20x.

Answer:

C

Step-by-step explanation:

Find the height (h ) above eye level and add 5 to give height from floor level.

Since the triangle is right use the tangent ratio to find h

tan60° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{h}{5}[/tex]

Multiply both sides by 5

5 × tan60° = h, hence

h ≈8.66

The height is 8.66 + 5 = 13.66 ≈ 14 ft ( to nearest foot )

Answer:

[tex]x = 230/3\\[/tex]

Step-by-step explanation:

Step 1:  Distribute

12x + 110 = 6(x + 100)

12x + 110 = (6 * x) + (6 * 100)

12x + 110 = 6x + 600

Step 2:  Subtract 6x from both sides

12x + 110 - 6x = 6x + 600 - 6x

6x + 110 = 600

Step 3:  Subtract 110 from both sides

6x + 110 - 110 = 600 - 110

[tex]6x = 490[/tex]

Step 4:  Divide both sides by 6

[tex]6x / 6 = 490 / 6[/tex]

[tex]x = 490 / 6[/tex]

Answer:

y=-4x-17

Step-by-step explanation:

You want to find the equation for a line that has a slope of -4 and a y-intercept of -17.

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

All you really have to do here is

replace m with -4, which is the slope you gave, and

replace b with -17, the y-intercept you gave,

in the equation y=mx+b.

The equation of the line that has a slope of -4 and a y-intercept of -17 is:

y=-4x-17.

D. The graph of h is the graph of g shifted 2 units to the left and 5 units down.

Step-by-step explanation:

Graph:  h(x) = g ( x + 2 ) - 5

x + 2 means the graph is shifted to left by 2 units.

-5 means to shift the graph down by -2 units

so, the graph of h is the graph of g shifted 2 units to the left and 5 units down.

You will have to use trig to solve this:

The side you have is adjacent to the known angle

The side you are looking for is opposite the known angle

Take all tickets to be adult tickets

$9 x 553 = $4977

Then..... $4977 - $3936 = $1041

The difference between the child and adult ticket is $3, so divide $1041 by $3

$1041 divided by $3 = 347

347 is the number of child tickets sold

347 x $6 = $2082

So 553 - 347 = 206 ( no. of adult tickets )

206 x $9 = $1854

Child tickets sold : 347

Adult tickets sold : 206

:0 ITS MAGIC IM SO SMART

Answer:

347 child tickets and 206 adult tickets are sold

Step-by-step explanation:

Let x be the no. of child tickets sold

Let y be the no. of adult tickets sold

A ticket office sold 553 tickets one day.

Equation becomes : [tex]x+y=553[/tex] ---A

Cost of 1 child ticket = $6

Cost of x child tickets = 6x

Cost of 1 adult ticket= $9

Cost of y adult tickets = 9y

Now we are given that the receipts totaled $3936.

So, Equation becomes : [tex]6x+9y=3936[/tex] ---B

Plot A and B

[tex]x+y=553[/tex] ---Green

[tex]6x+9y=3936[/tex] ---Purple

ANSWER

(-1,2)

EXPLANATION

The given quadratic expression is:

[tex]f(x) = {x}^{2} + 2x + 3[/tex]

The coefficient of the quadratic term is already 1.

So we add and subtract the square of half the coefficient of x.

[tex]f(x) = {x}^{2} + 2x + 1 - 1+ 3[/tex]

We factor the first three terms to obtain

[tex]f(x) =(x + 1)^{2} + 2[/tex]

This is now in the form:

[tex]f(x) = a({x - h)}^{2} +k[/tex]

Answer:

Step-by-step explanation:

Patrica got 80% correct.  She missed 4 problems, so that must have been the remaining 20% of the test.

Therefore:

4 = 20% x

Percent means out of 100, so:

4 = 1/5 x

x = 20

There were 20 problems on the test.

Answer:

y = [tex]\frac{2}{3}[/tex] x - 4

Step-by-step explanation:

Given y = f(x), then

y = f(x) + c represents a vertical translation

• If c > 0 then shift up by c units

• If c < 0 then shift down by c units

Here the translation is 4 units down ⇒ c = - 4, thus

y = [tex]\frac{2}{3}[/tex] x - 4

The equation of a line y = 2/3x moved 4 units down would be y = 2/3x - 4.

In the case of a vertical translation, the equation of a line y = mx + b is altered by adding or subtracting a constant value, which moves the line up or down on the coordinate plane. For example, with the given equation of a line, y = 2/3x, to translate it 4 units down, we subtract 4 from y. Therefore, the equation for the vertical translation would be y = 2/3x - 4.
