Answer:

See Below

Step-by-step explanation:

The length of the belt is the length around 2 inch radius wheel PLUS length around 8 inch radius wheel.

The length around a circular region is its circumference. The formula is:

[tex]C=2 \pi r[/tex]

Where

C is circumference

r is the radius

We sum up both, given first one radius is 2 and second one radius is 8, so we have:

[tex]2\pi r + 2 \pi r \\=2 \pi (2) + 2 \pi (8)\\=4\pi + 16 \pi\\= 20 \pi\\=62.83[/tex]

The length of the belt should be around 62.83 inches

Answer:

To solve this equation we need to get x by itself.

4x-6=10x-3, (the first step would be adding 6 to both sides.)

4x=10x+3 (the next step is the subtract ten from both sides.)

-6x=3 (Last step is the divide both sides by -6.)

x=-1/2

Answer: 3

Step-by-step explanation:

Move the decimal back to its point of origin

To multiply a number by a power of 10, you move the decimal point to the right by the number of zeros in the power of 10.

When multiplying a number by a power of 10, you can count the number of zeros in the power of 10 and move the decimal point that same number of places to the right.

In the case of multiplying 0.008 by 10, the power of 10 is 1, so you would move the decimal point one place to the right, resulting in 0.08.

Therefore, you multiply 0.008 by 10 to get 0.08.

Answer:

the answer is b 2

Step-by-step explanation:

Final answer:

Adding a sixth temperature of 83°F to the original data set increases the median temperature from 70°F to 71°F, which is an increase of 1°F. Thus, option A is correct.

Explanation:

The question is asking how much the addition of a sixth day's temperature of 83°F will increase the overall median temperature of the previously recorded five days.

First, we need to arrange the temperatures of the first five days in ascending order: 68°, 70°, 70°, 72°, and 75°. The median of these five numbers is 70°F, which is the middle value.

When we add a sixth temperature of 83°F, the new set of temperatures will be 68°, 70°, 70°, 72°, 75°, and 83°.

With an even number of data points, the median is the average of the two middle numbers which are now 70° and 72°F. The average of 70°F and 72°F is 71°F.

Thus, the new median is 71°F, which is a 1°F increase from the original median of 70°F.

Therefore, the correct answer is A) 1°.

To calculate the slope of a line we require any two points along the line.

Explanation:

suppose two points are given that is (x1,y1) (x2, y2) . The equation of a line is  y-y1=m(x-x1) , where m is referred to as the slope of the line .

To find m,

m= y2-y1/x2-x1 . Hence this way of finding slope is known as point- slope form. Another form is there known as slope- intercept form

y=mx+c.

But to find a slope , minimum amount of information that we require is points along the line.

Final answer:

To calculate the slope of a line, only two points on the line are needed. Slope is computed as the difference in y-coordinates divided by the difference in x-coordinates of these points.

Explanation:

To calculate the slope of a line, the minimum amount of information needed is any two points along the line. The slope is the rate of change between two points on a line and can be calculated using the formula slope (m) = (Y₂ - Y₁) / (X₂ - X₁), where Y₂ and Y₁ are the y-coordinates and X₂ and X₁ are the x-coordinates of the two points. It is not necessary to know the length of the line, the endpoints specifically, or the x and y intercepts separately.

The slope-intercept form of a linear equation, y = mx + b, shows that m is the slope and b is the y-intercept. Here, the y-intercept is simply the point where the line crosses the y-axis, but it is not required for calculating the slope when you have two points on the line.

4 = y - x

2. 2x+4y = 10

x+4y = 5

x+y = 5/4

Answer:

36

Step-by-step explanation:

9 times 4

The perimeter of a square is calculated by 4 times the length of one side. For a square plastic tarp with each side being 9 meters, the perimeter would be 36 meters.

The perimeter of a square can be calculated by using the formula: 4 x side length. In this case, the length of the side of the tarp is 9 meters. Therefore, to find the perimeter, you would multiply 4 (the number of sides in a square) by 9 (the lengths of one side). That calculation would look like this: 4 x 9 = 36 meters. So, the perimeter of the square plastic tarp is 36 meters.

Answer:

The angle measurement is 68 degrees

Step-by-step explanation:

The line NL is a straight line, so the angle is 180

NOM and LOM add up to the straight line

Then, subtract 112 from 180 to get 68 degrees as the answer

Answer:

68°

Step-by-step explanation:

1.) 112 + x = 180

2,) subtract 112 to both sides

112 + x = 180

-112       = - 112

         x  = 68

Answer:

Step-by-step explanation:

The largest monthly payment David can afford for the television set is $794.

To determine the largest monthly payment David can afford for the television set, we need to calculate his monthly expenses and subtract them from his net income. David's fixed monthly expenses consist of a rent payment of $450 and a student loan payment of $116. Therefore, his total monthly fixed expenses are $450 + $116 = $566.

We can subtract David's total monthly fixed expenses from his net income: $1,360 - $566 = $794. This is the maximum amount David can afford to allocate towards credit card payments and still stay within a safe debt load.

So, the largest monthly payment David can afford for the television set is $794.

Area scale

= (1 in)²: (3 ft)²

= 1 in²: 9 ft²

This means that 1 in² of the drawing represents an actual area of 9 ft².

Area of garden in the drawing

= 5(3.5)

= 17.5 in²

Area of actual garden

Answer:

Angle 4 is 144.

Step-by-step explanation:

Applying the definition of vertical angles, the measure of angle 4 is: 144°.

Vertical angles are a pair of angles that lie directly opposite each other and are equal in measure to each other.

m∠1 + m∠2 = 180° (linear pair)

Substitute

3x + 12x = 180

15x = 180

x = 12

∠4 and ∠2 are vertical angles, therefore:

m∠4 = m∠2 = 12x

Plug in the value of x

m∠4 = 12(12)

m∠4 = 144°

Therefore, applying the definition of vertical angles, the measure of angle 4 is: 144°.

Step-by-step explanation:

It can be rewritten as y = -x + 1.

The slope is -1 and the y-intercept is (0,1)

Final answer:

The equation y=1-x is indeed a linear equation, fitting the general form y = a + bx with a slope of -1 and y-intercept of 1.

Explanation:

Yes, y=1-x is a linear equation. In general, a linear equation can be written in the form y = a + bx, where a is the y-intercept and b is the slope. In this case, the equation y=1-x can be rewritten as y = (-1)x + 1, which clearly fits the form of a linear equation with a slope of -1 and a y-intercept of 1.

The graph of a linear equation is a straight line, and the equation y=1-x represents a straight line with a downward slope. Unlike nonlinear equations, such as y=xb where b is a power, linear equations represent a direct proportionality between y and x.
