in a state with a population of 2000000 the average vitizen spends 6000 on housing each year. what is the total spent on housing
Olenka [21]

Answer:

1.2 \times 10^{10} spents on housing for each year for the state.

Step-by-step explanation:

Given:

Population of State = 2000000

Average Citizen spends on housing = 6000

We need to find total spent on housing for the state.

For finding total spent on housing for state we need to multiply Population of state with average citizen spends on housing.

Total spent on housing for state = Population of State \times Average Citizen spends on housing = 2000000 \times 6000 = 12000000000

Now expressing the above in scientific notation we get;

Total spent on housing for state = 1.2 \times 10 ^{10}

In converting 9 inches to yards, what unit (omit the number) would you place
Anna35 [415]

Answer:

<u>9 inches are 1/4 or 0.25 yards and we used inches in the numerator and yards in the denominator for our ratio.</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

1 yard = 36 inches

2. In converting 9 inches to yards, what unit (omit the number) would you place  in the numerator of your ratio?

This is the ratio for calculating the answer:

36/1 = 9/x

36x = 9 *1

36x = 9

x = 9/36

x = 1/4 or 0.25 yards

<u>9 inches are 1/4 or 0.25 yards and we used inches in the numerator and yards in the denominator for our ratio.</u>

Trina has $1000 to purchase an open-top cylindrical dog pen in her backyard. She wants the height of the pen to be 5 feet. If th
RideAnS [48]

Answer:

C. 31.83 feet.

Step-by-step explanation:

We have been given that Trina has $1000 to purchase an open-top cylindrical dog pen in her backyard. She wants the height of the pen to be 5 feet.

First of all, we will find the surface area of dog pen using surface area of cylinder.

\text{Surface area of cylinder}=2\pi rh,where,

r = Radius of cylinder,

h = Height of cylinder.

\text{Surface area of cylinder}=2\pi r*5

\text{Surface area of cylinder}=10\pi r

Since the area of each square foot of pen costs $1, so in $1000 Trina can cover an area of 1000 square feet.

Now, we will set the surface area of cylinder equal to 1000 to solve for the radius.

1000=10\pi r

Upon dividing both sides of our equation by 10 pi we will get,

\frac{1000}{10\pi}=\frac{10\pi r}{10\pi}

31.8309886=r

r\approx 31.83

Therefore, the radius of the dog pen is 31.83 feet and option C is the correct choice.
