Answer:

Step-by-step explanation:

3000 W = 3 kW

3 kW(4hr/day)(30 day/month) = 360 kWh/month

360 kWh/month($0.15 / kWh) = $54

So about $75 when you add all the taxes and other fees that get added to a typical electric bill.

Adrian is driving to a concert and needs to pay for parking. There is an automatic fee of $7 just to enter the parking lot, and
photoshop1234 [79]

The money that Adrian would  have to pay for parking if he left his car in the lot for 3 hours is $13  and ther amount that Adrian has to pay if he left his car in the lot for t hours is $(2t + 7)

<h3>How to solve Algebra Word Problems?</h3>

We are given;

Fee for entering the Parking Lot = $7

Fee for one hour of parking = $2

Thus;

Fee for three hours of parking = 2 * 3 = $6

Total fee if he parks his car for 3 hours = $7 + $6

Total fee if he parks his car for 3 hours = $13

Total fee if she left the car for t hours = $(2t + 7)

Finally we conclude that the money that Adrian would  have to pay for parking if he left his car in the lot for 3 hours is $13  and ther amount that Adrian has to pay if he left his car in the lot for t hours is $(2t + 7)

If r = 3.2, what is the area of the shaded region? Round your answer to the nearest hundredth. Use your calculator's value of π.
MrRa [10]

Answer: The shaded area is 99.55 units squared.

Step-by-step explanation:

r = 3.2

Now, we can see that the sides of the square are equal to two times the diameter of the circles (or four times the radius of the circles), so the length of the sides of the square is:

L = 2*(2*3.2) = 12.8

The area of the square is A1 = L^2 = 12.8*12.8 = 163.84 units squared.

the shaded semicircle has a diameter of 4 times r (so the radius is 2 times r), and the area is equal to half the area of a circle:

A2 = (1/2)*pi*(2r)^2 = (1/2)*3.14*(6.4)^2 = 64.31 units squared.

And now we must subtract the area of the four smaller circles inside the square, the area of each one is:

A3 = pi*r^2 = 3.14*(3.2)^2 = 32.15 units squared.

Then the shaded area is:

A = A1 + A2 - 4*A3 = 163.84 + 64.31 - 4* 32.15 = 99.55 units squared.

At a zoo, 3 pandas eat a total of 181 1 2pounds of bamboo shoots each day. The male panda eats 3 times as much as the baby. The
S_A_V [24]

Answer:

6037.2 pounds of bamboo shoots does the female panda eat.

Step-by-step explanation:

Total pandas = 3

Total bamboo shoots eaten = 18112 pounds

Let baby panda eats bamboo = x

Male panda eats bamboo= 3x

Female panda eats bamboo = 2x

So, the equation will become

x+3x+2x=18112

Now solving the equation to find value of x

x+3x+2x=18112\\6x=18112\\x=\frac{18112}{6}\\x=3018.6

The value of x we get : x=3018.6

So, baby panda eats bamboo shoots = 3018.6 pounds

Male panda eats bamboo shoots = 3x = 3(3018.6) = 9055.8 pounds

Female panda eats bamboo shoots = 2x = 2(3018.6)= 6037.2 pounds

So, 6037.2 pounds of bamboo shoots does the female panda eat.
