Answer:

The cost incurred by Trevor's family per minute on shower water totals $0.005.

Step-by-step explanation:

The price of water is:

Cost = $0.20/liter

Water consumption over the past month:

Amount of water used = 72 liters

To calculate the total water expense:

Total water cost = Amount of water used × Cost

                           = 72 × 0.20

                           = $14.4/liter

The average time each individual spent showering is:

Average number of minutes = 480 minutes.

Total individuals in Trevor's household:

N = 6

Calculate the total shower duration for all 6 individuals:

Total amount of time = Average number of minutes × N

                                   = 480 × 6

                                   = 2880 minutes

Calculate the cost per minute for shower water:

Pay per minute on water = Total water cost ÷ Total amount of time

                                          = $14.4 ÷ 2880

                                          = $0.005

Therefore, Trevor's family pays $0.005 per minute for shower water.

Triangle XYZ is an equilateral triangle, meaning the sector's central angle measures 120 degrees, which is equivalent to 2π/3 radians. To find the area of a sector corresponding to a central angle β, we use the formula A = (1/2)r²*β, where β is expressed in radians. For this sector, the area calculation is A = (1/2)*2²*(2π/3) = 4π/3 square units.

In a basketball arena, all four sides are filled with people. If each side of the arena is 20 ft. X 30 ft., and each person take
lawyer [12517]

Answer:

960 individuals

Detailed explanation:

Given that each side of the basketball arena measures 20 ft by 30 ft, the area for one side would be calculated as 20ft * 30ft = 600ft².

As the arena’s four sides are all filled with people, the cumulative area will be 4*600 = 2400ft²

Each person occupies an area of 2.5ft², therefore, the total number of individuals present in the arena can be determined by dividing the total area encompassed by the four sides by the area each person occupies.

Total number of individuals in the arena = area of all four sides divided by area occupied by each person.

Total number of individuals in the arena = 2400/2.5

Thus, the result is 960 people.

- In the following diagram of triangle QRS, QR = 8 and QS = 17. Determine the value of sin Q. Show how you
PIT_PIT [12445]

Response:

SinQ=\frac{15}{17}

Step-by-step explanation:

We create the right triangle as illustrated in the attached image.

Δ QRS

Here, R represents the right angle

Given

QR = 8

QS = 17

Using the Pythagorean Theorem, we can determine RS:

QR^2+RS^2=QS^2\\8^2+RS^2=17^2\\RS^2=17^2-8^2\\RS^2=225\\RS=\sqrt{225}\\RS=15

Currently, the Sine ratio is known as:

Sin(\theta)=\frac{Opposite}{Hyotenuse}

Where \theta signifies the angle (in this case, angle Q)

The side opposite is RS (which measures 15)

While the hypotenuse is QS (which equals 17)

At this point,

SinQ=\frac{15}{17}

This is the value of SinQ.

We don't require the angle, so we will conclude here.

Consider the function represented by the equation y-6x-9=0. Which answer shows the equation written in function notation with x
babunello [11817]

Answer:

A. f(x) = 6x + 9

Step-by-step explanation:

The equation provided is:

y - 6x - 9 = 0

The requirement is to express this equation in function notation where x is the independent variable. This implies replacing y with f(x) and transferring the other components to the opposite side of the equation to achieve the desired format.

y - 6x - 9 = 0

y = 6x + 9

f(x) = 6x + 9

Thus, option A provides the correct response.
