Answer:  Possibly, 105 cm³ if it is a triangular prism,  or

Possibly 210 cm³ if it is a rectangular prism

Step-by-step explanation: Without knowing exactly what kind of prism it is, it is impossible to give an exact answer.

If the bases are triangles with altitude and and base of 5 and 6, anf the height of the prism is 7, the volume is

(6×5)/2 × 7

30/2 ×7

15 × 7 = 105 cm³ for a triangular prism

If the bases are rectangles with length and and width of 6 and 5, and the height of the prism is 7, the volume is

6×5×7 = 210 cm³ for a rectangular prism

Step-by-step explanation:

[tex]f(g(x) = 4(2x + 2) - 1 \\ 4(2(5) + 2) - 1 \\ 4(12) - 1 \\ 48 - 1 = 47[/tex]

Answer:

29,205

Step-by-step explanation:

100% - 17.5% = 82.5%

82.5% * 35,400 = answer

make percent a decimal

.825 * 35,400 = 29,205

29,205 is answer

The required current value of the ambulance is given as $29,205.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,

The value of an ambulance depreciated by 17.5% from the purchase price of $35,400 a year ago.

Current price = 35400[1 - 0.175]
Current price =  $29,205

Thus, the required current value of the ambulance is given as $29,205.

Answer:

60 miles

Step-by-step explanation:

distance = speed x time

45 minutes = 0.75 hours

0.75 x 80 = 60

Answer:%80 or 0.8

Step-by-step explanation:

Total = 7.50

Part of 7.50 is 6

The percentage of 6 in 7.50 is  6*100/7.50

0.8* 100

80%

Answer:

11, 37, 63, 89, 115, 141

Step-by-step explanation:

Subtract 89 from 115 and you get 26.

Subtract 115 from 141 and you get 26.

Its a pattern, subtract 26 from 89 and you get 63, keep subtracting 26.

Answer:

11, 37, 63, 89, 115, 141

Step-by-step explanation:

Every time you proceed right you add 26 to the last number.

Every time you go left you take away 26 from the last number

Hope this helps:)

(just add until 89 is 115 and add the answer to 115 and see if the answer adds up)

Answer:

12 bouquets

Step-by-step explanation:

Determine what the greatest common factor is in this case...

72/12 = 6 red roses

60/12 = 5 pink roses

48/12 = 4 yellow roses

As you can see the greatest common factor is 12. Therefore the greatest number of bouquets that the florist can make if no roses are left over should be 12 bouquets.

[tex]\overrightarrow{AB}+\overrightarrow{CD}=(-3,-7)[/tex]

Step-by-step explanation:

Vector Addition

We are given the points A=(1,3), B=(-4,5), C=(-2,10), D=(0,1). Find:

[tex]\overrightarrow{AB}+\overrightarrow{CD}[/tex]

First, find both vectors from the initial and final points:

[tex]\overrightarrow{AB}=(-4-1,5-3)=(-5,2)[/tex]

[tex]\overrightarrow{CD}=(0-(-2),1-10)=(2,-9)[/tex]

Now find the sum of both vector by adding the components separately:

[tex]\overrightarrow{AB}+\overrightarrow{CD}=(-5,2)+(2,-9)=(-3,-7)[/tex]

[tex]\boxed{\overrightarrow{AB}+\overrightarrow{CD}=(-3,-7)}[/tex]

Answer:

  B.  x +6y = 4.45; x +12y = 5.65

Step-by-step explanation:

The problem statement defines the variables for you. Using x and y for the cost of a loaf and the cost of an egg, respectively, each purchase can be represented by an equation of the form ...

  (number of loaves)x + (number of eggs)y = (amount spent)

The first purchase is described as

The second purchase is of a dozen eggs, which is 12 eggs. The description of this purchase can be ...

The situation can be represented by the equations shown in the attachment.

Answer:

Home to school through mall: 11 miles

Home to school through theater: 13 miles

Step-by-step explanation:

The route from home to school that passes the mall is x + 1 + x + 2 = 2x + 3.

The route from home to school that passes the theater is 2x + 1 + x = 3x + 1.

The route from home to school that passes the mall is 2 miles shorter than the route that passes by the theater.

2x + 3 = 3x + 1 - 2

2x + 3 = 3x - 1

-x = -4

x = 4

Home to school through mall:

2x + 3 = 2(4) + 3 = 11

Home to school through theater:

3x + 1 = 3(4) + 1 = 13

Answer:

Home to school through mall: 11 miles

Home to school through theater: 13 miles

==========================================

Work Shown:

The scalar (2/5a+6) multiplies with the matrix on the left side to get the matrix on the right side

So this is what your steps could look like

[tex](\frac{2}{5}a+6)\begin{bmatrix}3 \\ -2 \\ 7\end{bmatrix}=\begin{bmatrix}15 \\ -10 \\ 35\end{bmatrix}\\\\\\\begin{bmatrix}(\frac{2}{5}a+6)*3 \\ (\frac{2}{5}a+6)*(-2) \\ (\frac{2}{5}a+6)*7\end{bmatrix}=\begin{bmatrix}15 \\ -10 \\ 35\end{bmatrix}\\\\\\[/tex]

[tex]\begin{bmatrix}\frac{2}{5}a*3+6*3 \\ \frac{2}{5}a*(-2)+6*(-2) \\ \frac{2}{5}a*7+6*7\end{bmatrix}=\begin{bmatrix}15 \\ -10 \\ 35\end{bmatrix}\\\\\\\begin{bmatrix}\frac{6}{5}a+18 \\ -\frac{4}{5}a-12 \\ \frac{14}{5}a+42\end{bmatrix}=\begin{bmatrix}15 \\ -10 \\ 35\end{bmatrix}\\\\\\[/tex]

The last matrix equation leads to this system of equations

[tex]\begin{cases}\frac{6}{5}a+18=15 \\ -\frac{4}{5}a-12=-10 \\ \frac{14}{5}a+42=35\end{cases}\\\\\\[/tex]

If we pick any of those equations, and solve for 'a', then we'll get our answer.

---------------------

Let's say we pick the first equation

(6/5)a+18 = 15

(6/5)a = 15-18

(6/5)a = -3

a = -3(5/6)

a = -15/6

a = -5/2

--------------------

If we pick on the second equation, then,

(-4/5)a-12 = -10

(-4/5)a = -10+12

(-4/5)a = 2

a = 2(-5/4)

a = -10/4

a = -5/2

--------------------

Or we could solve the third equation for 'a'

(14/5)a+42 = 35

(14/5)a = 35-42

(14/5)a = -7

a = -7*(5/14)

a = -35/14

a = -5/2

-------------------

You only need to solve one equation to find 'a', though it's good practice to solve all three to see all three rows agreeing with one another.

The multiplication of the matrix by a constant will multiply for each term in the matrix value of the "a" given system of the matrix will be -2.5.

A matrix is a collection of numbers lined up in rows and columns to produce a rectangular array.

In computer graphics, where they have been used to describe picture transformations and other alterations, matrices have vital applications as well in many sectors.

As per the given system of the matrix.

When we multiply anything in a matrix then it will multiply to each and every term of the matrix.

Therefore the (2/5)a + 6 will be multiplied by 3,-2, and 7 each.

So the first term of the left-hand side matrix becomes,[(2/5)a + 6]3

If we compare two matrices then each corresponding term will be the same.

Therefore, the first term of the left-hand matrix = first term of the right-hand matrix

[(2/5)a + 6]3 = 15

6a/5 + 18 = 15

6a/5 = -3

6a = -15

a = -15/6 = -2.5

Hence "The value of the "a" given system of the matrix will be -2.5".
