Answer:

[tex]Surface\ Area = 179.25cm^2[/tex]

Step-by-step explanation:

Given

See attachment for figure

Required

Determine the surface area

To do this, we calculate the surface area of each individual shape.

For the semicircle.

[tex]Area = \frac{1}{2}\pi r^2[/tex]

Here, the diameter (D) is given

[tex]D = 10cm[/tex]

The radius is:

[tex]r = \frac{1}{2}D[/tex]

[tex]r = \frac{1}{2}*10cm[/tex]

[tex]r= 5cm[/tex]

So, the area is:

[tex]Area = \frac{1}{2} * 3.14 * (5cm)^2[/tex]

[tex]Area = \frac{1}{2} * 3.14 * 25cm^2[/tex]

[tex]Area = 39.25cm^2[/tex]

For the triangle, the area is:

[tex]Area = \frac{1}{2}bh[/tex]

[tex]Area = \frac{1}{2} * 10cm * 8cm[/tex]

[tex]Area = 40cm^2[/tex]

For the rectangle

[tex]Area = Length * Width[/tex]

[tex]Area = 20cm * 5cm[/tex]

[tex]Area = 100cm^2[/tex]

So, the surface area is:

[tex]Surface\ Area = 39.25cm^2 + 40cm^2 + 100cm^2[/tex]

[tex]Surface\ Area = 179.25cm^2[/tex]

Could you put a picture it could be very easier to solve for you

Answer:

The total distance in miles at x = 2 hours will be 543.2 miles.

Step-by-step explanation:

Given

Given the linear model function

y = -67.9x +679

where

y represents the distance, in miles y, is a function of time, x, in hours

To determine:

Use the model to calculate the total distance, in miles, at x = 2 hours

substituting x = 2 in the function

y = -67.9x +679

y = -67.9(2) +679

y = -135.8 + 679

y = 543.2 miles

Therefore, the total distance in miles at x = 2 hours will be 543.2 miles.

Answer:

60%

Step-by-step explanation:

1: 15 divided by 25 to get 0.6

2: multiple 0.6 by 100 to get 60%

Answer:

50% value change.

Step-by-step explanation:

A 100% increase from 10 would be 20. It's the equivalent of doing 10 times 2. We need 15 though which is half the distance in value to 10 than 20 is. Half of 100% is 50%.

Therefore, $15 is a 50% percent change from $10.

Answer:

[tex]\frac{1}{4}[/tex]

Step-by-step explanation:

In this question, we have to find the slope with the given coordinates.

To find our slope, we would use the slope formula: [tex]m = \frac{y2-y1}{x2-x1}[/tex]

Plug in your coordinates and solve:

[tex]m = \frac{18-12}{40-16}\\\\m=\frac{6}{24}[/tex]

Simplify the fraction:

[tex]m=\frac{1}{4}[/tex]

The slope would be [tex]\frac{1}{4}[/tex]

Answer:

Yes, (2, 10) is a solution to this system:

y = 4x + 2

y = x + 8

Step-by-step explanation:

When graphed, the two equations cross at (2,10) making it a solution.

Answer:

Yes

Step-by-step explanation:

If y=4x+2 and y=x+8, then 4x+2=x+8

4x+2=x+8

4x=x+6

3x=6

x=2

Plugging this into the original equation "y=x+8", we obtain the result that y=10.

This means, (2, 10) is a solution  to the system.

Answer:

$148,000 was the selling price

Answer:

$148,000

Step-by-step explanation:

S = selling price

.06* S = 8880

S = 8880/.06

S = 148000

Answer: m^3

Step-by-step explanation:

Taking the square root of something is the same as raising it to the half power the square root of 4 is equal to 4^(1/2). This hold true with any root, not just square root. M^(3b) to the b root is equal to m^(3b x (1/b)). Ignore the base (m) for a second and the exponents make 3b x (1/b) which equals (3b/b). The b on the top and bottom cancel and you’re left with a 3. The answer is m^3

Answer:

No, is the answer. :)

Step-by-step explanation:

Answer:

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

Step-by-step explanation:

[tex] \frac{ {x}^{2} - 8x + 16 }{ {x}^{2} - 7x + 12} [/tex]

Lets split the numerator and denominator.

[tex] = > \frac{ {x}^{2} - 4x - 4x + 16}{ {x}^{2} - 3x - 4x + 12} [/tex]

Lets factorise the numerator and denominator.

[tex] = > \frac{x(x - 4) - 4(x - 4)}{x(x - 3) - 4(x - 3)} [/tex]

[tex] = > \frac{(x - 4)(x - 4)}{(x - 3)(x - 4)} [/tex]

Cancelling x - 4 from numerator and denominator ,

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

Answer:

The y-intercept b = 4.

Please also check the attached graph.

Step-by-step explanation:

We know that the slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

Given the equation

3y = 6x + 12

Let us convert the equation into the slope-intercept form by dividing the equation by 3

y = 2x + 4

Thus, the equation into the slope-intercept form is:

y = 2x + 4

now comparing with the slope-intercept form of the line equation

Therefore, the y-intercept b = 4

Determining the y-intercept through Graph:

Please also check the attached graph of the equation  3y=6x +12.

We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

From the graph, it is clear that:

at x = 0, the value of y = 4

Thus, the point (0, 4) represents the y-intercept of the equation 3y=6x +12 where y = 4 is the y-intercept.
