Complete question:

The park closes at 2:30 P.M. There is a 15−minute break between each game played at the park, and each game takes the same amount of time as Hamid's soccer game. How many more games can be played before the park closes? Hamid's soccer game time is 7:00 to 9:15

Answer:

2 more games can be played before the park closes.

Step-by-step explanation:

Given that Hamid's soccer game time is from 7:00 to 9:15 and there's a 15 minute break between games played, the next game time would be: 9:15 + 15 = 9:30

The time for each game would be calculated as:

stop time - start time = 9:15 - 7:00 = 2:15.

Thus, each game time = 2hrs 15mins

The next game time would be:

9:30 + 2:15 = 11:45

This means the next game would be from 9:30 to 11:45

After this, there would be another game(a second extra game) since the park closes at 2:30PM.

Therefore, the next game time would be:

11:45 + 15 mins break = 12:00

The game duration =

12:00 + 2hrs 15 mins = 14:15 or 2:15PM

Considering the fact that the park closes by 2:30 PM, 2 more games will be played.

Answer:

Air pressure = [tex]4.6\frac{\text{lb}}{\text{in}^{2} }[/tex]

Step-by-step explanation:

Relationship between air pressure and altitude can be modeled by,

P = 14.7e[tex]14.7e^{-0.00004h}[/tex]

Where P = Air pressure

and h = altitude above the sea level

Air pressure on Mount Everest having altitude = 29028 feet abve the sea level will be,

P = [tex]14.7e^{-0.00004\times 29028}[/tex]

  = [tex]14.7\times e^{-1.16112}[/tex]

  = 4.603

  ≈ 4.6 [tex]\frac{\text{lb}}{\text{in}^{2} }[/tex]

Therefore, air pressure on Mount Everest = 4.6 [tex]\frac{\text{lb}}{\text{in}^{2} }[/tex]

Answer:

27π

Step-by-step explanation:

First, find the area as though the circle were complete.

A = πr²

A = π(6)²

A = 36π

Now, if you look at the diagram, you can see that the chunk missing forms a 90 degree angle.  In a circle, there is 360 degrees in total.  This means that only 3/4 of the circle is left.  Multiply the area by 3/4.

36π × 3/4 = 27π

The area is 27π.

Answer:

No

Step-by-step explanation:

They are independent iff:

P(F & D) = P(F) × P(D)

15.278/100 = (55/100) × (27.778/100)

0.15278 = 0.125279 (false)

$857.58 is the price of car after 4 years.

percentage, a relative value indicating hundredth parts of any quantity.

Given,

Dan buys a car for £900.

It depreciates at a rate of 1.2% per year

We need to find the cost of car after 4 years.

1.2/100=0.012

Now multiply 0.012 with 900

10.8

So for first year it will be 900-10.8=889.2

0.012×889.2

10.67

For second year 889.2-10.67=878.53

0.012×878.53=10.54

For third year 878.53-10.54=867.99

0.012×867.99=10.41

For fourth year 867.99-10.41=857.58

Hence, after 4 years the price of car will be 857.58.

y = 2x² + 2x - 3

x = -2 -1 0 1 2

Answer:

Complete table of values

x:   -2        -1         0          1          2

y:    1          -3       -3          1         9

Step-by-step explanation:

Given;

y = 2x² + 2x - 3

To complete the table of values of the equation above, we substitute the value of x into the given equation and solve for y.

when, x = -2

y = 2(-2)² + 2(-2) - 3

y = 8 - 4 - 3

y = 1

when x = -1

y = 2(-1)² + 2(-1) - 3

y = 2 - 2 - 3

y = -3

when x = 0

y = 2(0)² + 2(0) - 3

y = 0 - 0 - 3

y = -3

when x = 1

y = 2(1)² + 2(1) - 3

y = 2 + 2 - 3

y = 1

when x = 2

y = 2(2)² + 2(2) - 3

y = 8 + 4 - 3

y = 9

Complete table

x:   -2        -1         0          1          2

The inverse is 1/7x +2

Step-by-step explanation:

y = 7x - 14

Exchange x and y

x = 7y-14

Solve for y

Add 14 to each side

x+14 = 7y-14+14

x+14 = 7y

Divide each side by 7

(x+14)/7 = 7y/7

1/7x +2 = y

The inverse is 1/7x +2

Answer:

g^-1(x)=x/7+2

Step-by-step explanation:

Answer:

18 inches

Step-by-step explanation:

Given: The heights of both cylinders are 48 inches and 32 inches. Diameter of the larger cylinder is 12 inches

To find: diameter of the larger cylinder

Solution:

Height of the larger cylinder (H) = 48 inches

Height of the smaller cylinder (h) = 32 inches

Diameter of the smaller cylinder (d) = 12 inches

Radius of the smaller cylinder (r) = d/2 =12/ 2= 6 inches

As two cylinders are similar, their heights and radii are proportional.

[tex]\frac{r}{h}=\frac{R}{H}\\\frac{6}{32}=\frac{R}{48}\\R=\frac{6}{32}\times 48=9\,\,inches[/tex]

Diameter of the larger cylinder = 2R = 2(9) = 18 inches

Answer: pencil (x) = 3.00, notebook (y) = 4.00

Step-by-step explanation:

Let pencils be denoted using 'x', and notebooks 'y'.

4x+12y = 60, 14x+7y=70

Let us use the method of elimination. However, neither variable has the same coefficient, so let us multiply the first equation using 7, and the second using 2.

7(4x+12y = 60) => 28x+84y=420

2(14x+7y=70) => 28x+14y=140

Let us subtract the second equation from the first. This eliminates the first variable x, and gives the equation 70y=280

Dividing either side of the equation by 70, we get y=4.

If we substitute (plug in) y=4 for the first equation we get x=3
