Again, use the area of a circle formula

A=pi(radius)2
A= 3.14(11)2
A=380.133 ft2

The area covered by the water will be 7850 square feet. The correct option is C.

What is the area of the circle?

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the circle in a two-dimensional plane is called the area of the circle.

Given that each rotating sprinkler in the park can water a circular section of grass that has a radius of 50 feet.

The area of the circle will be calculated by the formula below,

A = πr²

A=3.14 x ( 50 )²

Answers

Answer:

D;

(x + 1/2)^2 + (y- √57)^2 = 81

Step-by-step explanation:

Mathematically, the general equation of a circle is given as;

(x-a)^2 + (y-b)^2 = r^2

where (a,b) represents the circle center and r represents the radius of the circle

Thus, we have this as follows;

(a,b) = (-1/2, √57) , r = 9

Substituting these values;

(x + 1/2)^2 + (y- √57)^2 = 9^2

(x + 1/2)^2 + (y- √57)^2 = 81

Find JK................

Answers

Answer:

24 unit

Step-by-step explanation:

From the question,

JK = 2×NK.................... Equation 1

Using pythagoras theorem,

a² = b²+ c²................. Equation 2

From the diagram,

a = 15 unit, b = 9 unit, and c = NK

Substitute these values into equation 2

15² = 9²+(NK)²

Solve for NK

225 = 81+(NK)²

(NK)² = 225-81

(NK)²  = 144

NK = [tex]\sqrt{144}[/tex]

NK = 12 unit.

Substitute these value of NK into equation 1

JK = 2×12

JK = 24 Unit.

Find the error for the proposed solution. Then correct the proposed solution.
2x + 18 = 16
2x = 34
2x 34
2 2
X = 17

Answers

Answer:

The error is in the second line.

x = -1

Step-by-step explanation:

When solving for "x", you are trying to isolate it, or move everything else to the other side. You may have learned that "what you do to one side, you do to the other" .

2x + 18 = 16

2x = 34               18 was added to the right side, but not to the other.

If you add 18 on both sides, then the equation would be:

2x + 36 = 34       "x" is not being isolated.

Instead, you should subtract 18 from 16.

Correct solutions steps:

2x + 18 = 16

2x + 18 - 18 = 16 - 18     Subtract 18 from both sides to cancel out 18

2x = -2

2x/2 = -2/2                     Divide both sides by 2

x = -1                              Final answer

A salesperson receives a base salary of $35,000 and a commission of 10% of the total sales for the year. If a salesperson sells $250,000 worth of merchandise, what is her total income for the year, including her base salary?

Answers

Answer:

$60,000

Step-by-step explanation:

Given data

Base salary=$35000

commssion= 10%

Sales=  $250,000

Let us find the commission

=10/100* 250,000

=0.1*250,000

=25000

Hence the total income is

=25000+35000

=$60,000

1. A line has a slope of 6 and includes the
points (-1, q) and (0, -7). What is the
value of q?

Answers

Answer:

q = - 13

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to 6

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 1, q) and (x₂, y₂ ) = (0, - 7)

m = [tex]\frac{-7-q}{0+1}[/tex] = - 7 - q , then

- 7 - q = 6 ( add 7 to both sides )

- q = 13 ( multiply both sides by - 1 )

q = - 13

Answer:

q = -13?

Step-by-step explanation:

the equation is y = mx + c

m is the gradient

c is the y-intercept

where the line crosses the y axis

If 6 is the gradient then the equation is

y = 6x + c

Find c by using the coordinates given:

-7 = ( 6× 0) +c

-7 = 0 + c

c = -7

the equation is y = 6x -7

Substitute the other coordinates to find q:

y or q = (6 ×-1) - 7

q = -6 -7

q = -13

If it costs $55,000 to put on a magic show for two weeks in the estimated revenue is $15,000 per night for 14 nights what will the stadiums profit be

Answers

Answer:

$155,000

Step-by-step explanation:

You need to first multiply revenue of one night by 14 ($210,000) and then subtract the cost ($55,000) from it. You would get $155,000.

The profit will be $155,000.

What is profit?

Profit is the money earned by a business when its total revenue exceeds its total expenses.

Given that the costs $55,000 to put on a magic show for two weeks in the estimated revenue is $15,000, we need to find the profit,

So,

The cost of the magic show for two weeks is given as $55,000, The revenue is estimated as $15,000 per night.

As the show continued for 2 weeks or 14 nights, so the total revenue is,

= 15000 x 14 = $210,000

∵ Profit = Revenue - cost

Profit = $210,000 - $55,000

Profit = $155,000

Hence the profit will be $155,000.
