Answer:

300 minutes

Step-by-step explanation:

Given

10 feet in 40 minutes

Required

Determine the time to shovel 75 feet

Let the required be represented with x

First, we need to represent the given and required as ratios.

[tex]Given = 10 : 40[/tex]

[tex]Required = 75 : x[/tex]

Since you work at steady rate, then both ratios are equivalent.

[tex]10 : 40 = 75 : x[/tex]

Convert to fractions

[tex]\frac{10}{40} = \frac{75}{x}[/tex]

[tex]\frac{1}{4} = \frac{75}{x}[/tex]

Solve forx

[tex]x * 1 = 75 * 4[/tex]

[tex]x = 300[/tex]

Answer:

y = -3x + 7

Step-by-step explanation:

Using any 2 pairs of values, say (-3, 16) and (-1, 10), therefore, rate of change of the data given = [tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{10 - 16}{-1 -(-3} = \frac{-6}{2} = -3 [/tex].

We would get the same rate of change if we use any other two pairs of values in the data given.

Therefore, the data can be modeled by a linear equation because the rate of change remains constant all through.

To represent y as a function of x, find b, since we know the rate of change (m).

Substitute x = -3, y = 16 and m = -3 in y = mx + b.

Thus:

16 = (-3)(-3) + b

16 = 9 + b

Subtract 9 from each side

16 - 9 = b

7 = b

b = 7

Substitute m = -3 and b = 7 in y = mx + b

The function would be:

✅ y = -3x + 7

Step-by-step explanation:

The maximum amount of profit the company can make is $543

Let y represent the amount of profit and x represent the selling price.

The relationship between x and y is:

y = -4x² + 141x – 703

The maximum profit is at dy/dx = 0, hence:

dy/dx = -8x + 141

-8x + 141 = 0

8x = 141

x = 17.625

The maximum profit is:

y = -4(17.625)² + 141(17.625) – 703 = 543

The maximum amount of profit the company can make is $543

Answer:

Kiran is jogging at 9.6 miles per hour.

Step-by-step explanation:

We can find the speed of Kiran as follows:

[tex] v = \frac{x}{t} [/tex]

Where:

v: is the speed =?

x: is the distance = 24 miles

t: is the time

If Clare and Kiran started walking at 8 am and they get to their destination at 10:30 am, then the time is:

[tex] t = 10:30 - 8:00 = (10 h + 30min*\frac{1 h}{60 min}) - 8 h = 2.5 h [/tex]

Then, the speed of Kiran is:

[tex] v = \frac{x}{t} = \frac{24 miles}{2.5 h} = 9.6 miles/h [/tex]

Therefore, Kiran is jogging at 9.6 miles per hour.

I hope it helps you!

Answer:

35 hotdogs

Step-by-step explanation:

You are running a concession stand at a basketball game. You are selling hotdogs and sodas.

Let the number of hot dogs be represented by x

The number of soda be represented by y

You sold a total of 87 hotdogs and sodas combined

x + y = 87

x = 87 - y

Each hotdog cost $1.50 and each soda cost $0.50. At the end of the night you made a total of $78.50.

Hence we have the equation:

$1.50 × x + $0.50 × y = $78.50

1.50x + 0.50y = 78.50

Substitute 87 - y for x

1.50(87 - y) + 0.50y = 78.50

130.5 - 1.50y + 0.50y = 78.50

Collect like terms

- 1.50y + 0.50y = 78.50 - 130.50

-1.00y = -52

y = -52/-1

y = 52 sodas

How many hotdogs did you sell?

Using the equation:

x = 87 - y

x = 87 - 52

x = 35 hotdogs

Hence, you sold 35 hotdogs

Answer:

B. 6 field goals

Step-by-step explanation:

Given

[tex]Attempts = 15[/tex]

[tex]Scored = 40\%[/tex]

Required

Determine the number of goals scored

To do this, we simply multiply the number of attempts by the percentage scored.

[tex]Number = Attempts * Scored[/tex]

[tex]Number = 15 * 40\%[/tex]

Convert % to decimal

[tex]Number = 15 * 0.40[/tex]

y=0,3

x=-4,0

(-4,3)

The required coordinate of the image of p is under y = -1 is given as (-4, 4).

Coordinate, is represented as the values on the x-axis and y-axis of the graph. while the coordinate x is called abscissa and the coordinate the y is called ordinate.

Here,
Coordinates of point P = (-4, 3)

Now,
[tex]R_{y = -1}(p)[/tex]

The question of the image is given that
(x, y) ⇒ (x, -[y + 1])
        = (-4, -[3 + 1]) = (-4, -4)

Answer:

Step-by-step explanation:

Use the slope-intercept form to find the slope and y-intercept.  

The slope-intercept form is  y = m x + b , where  m  is the slope and  b  is the y intercept.

y = m x + b

Find the values of  m  and  b  using the form  y = m x + b .

m =− 5 3 b = 2

The slope of the line is the value of  m , and the y-intercept is the value of  b .

Slope:  

− 5 3

y-intercept:  2

Any line can be graphed using two points. Select two  x  values, and plug them into the equation to find the corresponding  y  values.

Choose  0  to substitute in for  x  to find the ordered pair.

Replace the variable  x  with  0  in the expression.

f ( 0 ) = − 5 ( 0 ) 3 + 2

Simplify the result.

Simplify each term.

Cancel the common factor of  0  and  3 .

Factor  3  out of  5 ( 0 ) .

f ( 0 ) = − 3 ( 5 ⋅ ( 0 ) ) 3 + 2

Cancel the common factors.

Factor  3  out of  3 .

f ( 0 ) = − 3 ( 5 ⋅ ( 0 ) ) 3 ( 1 ) + 2

Cancel the common factor.

f ( 0 ) = − 3 ( 5 ⋅ ( 0 ) ) 3 ⋅ 1 + 2

Rewrite the expression.

f ( 0 ) = − 5 ⋅ ( 0 ) 1 + 2

Divide  5 ⋅ ( 0 )  by  1 .

f ( 0 ) = − ( 5 ⋅ ( 0 ) ) + 2

Multiply  5  by  0 .

f ( 0 ) = − 0 + 2

Multiply  − 1  by  0 .

f ( 0 ) = 0 + 2

Add  0  and  2 .

f ( 0 ) = 2

The final answer is  2 .

2

The  y  value at  x = 0  is  2 .

y = 2

Choose  3  to substitute in for  x  to find the ordered pair.  

Replace the variable  x  with  3  in the expression.

f ( 3 ) = − 5 ( 3 ) 3 + 2

Simplify the result.

Simplify each term.

Cancel the common factor of  3 .

Cancel the common factor.

f ( 3 ) = − 5 ⋅ 3 3 + 2

Divide  5  by  1 .

f ( 3 ) = − 1 ⋅ 5 + 2

Multiply  − 1  by  5 .

f ( 3 ) = -5 +2

Add  − 5  and  2 .

f ( 3 ) = − 3

The final answer is  − 3 .

− 3

The  y  value at  x = 3  is  − 3 .

y = − 3

Create a table of the  x  and  y  values.
