The multiplication model represented by the image is given as follows:

12(4 x 10) + (3 x 10) + (6 x 10) + 18.

A multiplication operation is equivalent to consecutive additions.

For the green squares, the following addition is obtained:

10 + 10 + 10 + 10 + 6.

(which is the number of squares painted green).

Considering a multiplication with consecutive additions, it is written as follows:

4 x 10 + 6.

For the red squares, the expression is:

4 + 4 x 10 + 2 = 4 x 10 + 6.

For the blue squares, the expression is:

8 + 3 x 10 + 8

3 x 10 + 16

For the white squares, the expression is:

2 + 6 x 10

Hence the total model is calculated as follows:

4 x 10 + 6 + 4 x 10 + 6 + 3 x 10 + 16 + 2 + 6 x 10

(4 x 10)(6 + 6) + (3 x 10) + (6 x 10) + 18.

12(4 x 10) + (3 x 10) + (6 x 10) + 18.

Both Sheila and Bob together can wash the car in 10 minutes

Calculating work :

The formulas to find work and time is given by

Time Taken = 1 / Rate of Work

Rate of Work = 1 / Time Taken

If a work can be done in x number of days, then the work can be done in one day = 1/x

Total Work done = Number of Days × Efficiency ( of the person or machine )

Given that,    

Sheila can wash her car in 15 minutes

Let us consider washing the car is 1 unit of work

Then the work can done by Sheila in 1 minute = 1/15  

Bob take twice as long as Sheila to wash the same

Bob can wash the same car in 30 minutes

Then the work can done by Bob  in 1 minute = 1/30  

From above calculation,

The work can be done by Sheila and Bob = (1/15 + 1/30)

= (2+1) /30 = 3/30 = 1/10  

So the efficiency of Both Sheila and Bob per minute = 1/10

Let Both can complete the work in x minutes

As we know Total Work done = time × Efficiency

⇒ 1 = x × 1/10

⇒ x = 1 × 10

⇒ x = 10 minutes

Therefore,

Both Sheila and Bob together can wash the car in 10 minutes

Answer:

I'll do #17 as an example of how to do the others. #15 doesn't make sense.  What is "= ≤⁄x?"

Step-by-step explanation:

17. (-3, 2); y=-4

y=4 is a horizontal line, where all values of y are 4, regardless of x.  A horizontal line has a slope of 0.  [Y does not depend on x].

That leaves us with y =0x + b

For this line to go through point (-3,2), it would have to have a y-intercept (b) of 2 [b is the value of y when x=0].  Since y=0 regardless of x, b must be 2.

The parallel line that goes through (-3,2) is:

y = 0*x + 2, or

y = 2

The equation of the quadratic function f(x) is f(x) = (x + 4)(x - 2)

From the question, we have the following parameters:

Roots = -4 and 2

Point = (1, -5)

Rewrite the given parameters as

Roots: x = -4 and x = 2

Point: (x, y) = (1, -5)

Recall that:

x = -4 and x = 2

This gives

x + 4 = 0 and x - 2 = 0

Multiply the equations

So, we have

y = a(x + 4)(x - 2)

When (x, y) = (1, -5), we have

-5 = a(1 + 4)(1 - 2)

This gives

a = 1

Substitute a = 1 in y = a(x + 4)(x - 2)

y = (x + 4)(x - 2)

Hence, the equation of f(x) = (x + 4)(x - 2)

In order to get the volume of the irregular figure, let's cut it into two regular figures. See the cut below.

First, let's calculate the volume of the upper part.

The dimensions of the upper part are 7cm by 3 cm by 3 cm. Since the shape is a rectangular prism, let's multiply 7, 3, and 3.

Hence, the volume of the upper figure is 63 cm³.

Let's now calculate the volume of the lower figure.

The dimensions of the lower figure are 5cm by 4 cm by 3 cm. Since this is a rectangular prism too, let's multiply the dimensions.

The volume of the lower figure is 60 cm³.

Let's add the volume of the two figures to get the volume of the entire irregular figure.

Therefore, the entire volume of the given irregular figure is 123 cm³.

33,800,000 are total distinct six characters license plates possible such that the two letters must appear next to each other. We can solve it by using combination formula ( ⁿCr ) .

Total number of digits are 10 i.e., 0,1,2,3,4,5,6,7,8,9. We have given the option to select any four digits out of 10 with repetition. So, we use combination formula

ⁿ C r = n!/(r! ×(n-r)! )

For 1ˢᵗ digit, the number ways to choose the 1ˢᵗ digit is ¹⁰C ₁= 10

For 1ˢᵗ letter, the number of ways to choose the 1ˢᵗ letter is ²⁶C ₁= 26

There are 10×10×10×10 = 10⁴ ways to choose four digits . In a similar way, the total number of letters for choice is 26 ; i.e., from A to Z. We were given the task of choosing two letters from a list of 26 , which were not necessarily distinct .

There are 26×26 = 26²ways to choose the two letters . For the letters to be next to each other, they can be the 1ˢᵗ and 2ⁿᵈ, 2ⁿᵈand 3ʳᵈ, 3ʳᵈand 4ᵗʰ, 4ᵗʰand 5ᵗʰ, 5ᵗʰ and 6ᵗʰ characters . So, there are 6-1 = 5 are choices for the positions of the letters .

We have to solve this linear equation for x:

The answer is x=19/6

According to the theorem, the corresponding angles, formed by a transversal on a pair of parallel sides, are always equal.

Also, the sum of angles on a straight line is 180 degree.

The angles 5 and 7 constitute a pair of corresponding angles, formed by the transversal 'r' on the pair of parallel sides 'p' and 'q'. So they must be equal,

The angles 4 and 5 constitute a straight line, so they must add up to be 180 degrees,

Thus, the angle 4 measures 49 degrees.

The values of x and y after solving the given system of equations are respectively.

According to the question,

We have the following two equations:

y = 2x+3 ....(1)

y = 4x-1 .....(2)

Now, we can put the value of y from equation 1 in equation 2:

2x+3 = 4x-1

Now, we can change sides as it will not affect the result.

4x-1 = 2x+3

Moving 2x from the right hand side to the left hand side will result in the change of sign from plus to minus:

4x-2x-1 = 3

2x-1 = 3

2x = 3+1

2x = 4

x = 4/2

x = 2

Now, we can put the value of x in equation 1 to find the value of y:

y = 2x+3

y = 2*2+3

y = 4+3

y = 7

Hence, the value of x is 2 and the value of y is 7 after solving the equations.

Answer: A z=9

Step-by-step explanation:

Answer:

z = 12

Step-by-step explanation:

To understand the equation, you must first know that m∠a = 108°. It equals that because a regular five-sided polygon has an interior angle of 108° each.

Next, you would want to group all constants to the right side of the equation. By doing so, you want to subtract 72 from both sides.

(3z + 72) - 72 = 108 - 72

3z = 36

Lastly, you want to isolate the z by dividing 36 by 3.

z = 36 ÷ 3

z = 12
