Suzanne wants to put a fence around her square garden. If the garden covers an area of 49ft^2, how many feet of fencing does she

lina2011 [118]

Answer:

The area for a square is given by:

$A = x^2$

And we can find the dimension for one side like this:

$x = \sqrt{A}$

Replacing we got:

$x = \sqrt{49 ft^2}= 7ft$

Then since we are interested in the how many feet of fencing does she need, we can find the perimeter given by:

$P = 4x$ and replacing we got:

$P = 4*7 ft = 28 ft$

Step-by-step explanation:

For this case we know that Suzanne want to put a fance around a square garden with an area of 49 ft^2

The area for a square is given by:

$A = x^2$

And we can find the dimension for one side like this:

$x = \sqrt{A}$

Replacing we got:

$x = \sqrt{49 ft^2}= 7ft$

Then since we are interested in the how many feet of fencing does she need, we can find the perimeter given by:

$P = 4x$ and replacing we got:

$P = 4*7 ft = 28 ft$

You are driving in France and see the price of gasoline is 2.099 euros per liter. Use the facts below to calculate the price in

Dahasolnce [82]

Answer: $\$10.503$

Step-by-step explanation:

Knowing that the price of gasoline in France is 2.099 euros per liter, you can follow these steps in ordere to calculate the price of the gasoline in US dollars per gallon:

1. Convert 2.099 euros to US dollars:

$(2.099\ euros)(\frac{1\ US\ dollar}{0.7564\ euros})=2.774\ US\ dollars$

Then, the price in US dollars per liter is $2.774\ US\ dollars\ per\ liter$

3. Knowing that:

$1\ liter=1.0567\ quarts\\\\4\ quarts = 1\ gallon$

You can make the conversion from 1.0567 quarts to gallons:

$(1.0567\ quarts)(\frac{1\ gallon}{4\ quarts})=0.2641\ gallons$

4. Set up the following proportion:

$\frac{2.774}{0.2641}=\frac{x}{1}$

Where "x" is the the price in US dollars per gallon.

5. Solving for "x", you get:

$\frac{(2.774)(1)}{(0.2641)}=x\\\\x=10.503$

Two customers took out automobile loans. Katy took out a 5-year loan for $18,000 and paid 7.00% annual simple interest. Frank to

Sophie [7]

Answer:

The difference between the amounts of interest Katy and Frank paid for their loans is $180

Step-by-step explanation:

The formula of the simple interest is I = Prt, where

P is the amount of the loan
r is the interest rate in decimal
t is the time

Katy took out a 5-year loan for $18,000 and paid 7.00% annual simple interest

∵ The amount of her loan is $18,000

∴ P = 18,000

∵ The annual simple interest is 7%

∴ r = 7% = 7 ÷ 100 = 0.07

∵ The loan is for 5 years

∴ t = 5

- Substitute these values in the formula above

∴ I = 18,000(0.07)(5)

∴ I = 6,300

∴ Katy will pay $6,300 interest for her loan

Frank took out a 6-year loan for $18,000 and paid 6.00% annual simple interest

∵ The amount of his loan is $18,000

∴ P = 18,000

∵ The annual simple interest is 6%

∴ r = 6% = 6 ÷ 100 = 0.06

∵ The loan is for 6 years

∴ t = 6

- Substitute these values in the formula above

∴ I = 18,000(0.06)(6)

∴ I = 6,480

∴ Frank will pay $6,480 interest for his loan

∵ The difference between their interests = 6,480 - 6,300

∴ The difference between their interests = $180

The difference between the amounts of interest Katy and Frank paid for their loans is $180

Use the information given to write the equation of the circle.

aliina [53]

Answer:

(x +9) ^2 + (y +7)^2 = 289

Step-by-step explanation:

We know the equation of a circle can be written as

(x-h) ^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius

We are given the diameter so we can find the radius

r = d/2 = 34/2 = 17

(x- -9) ^2 + (y- -7)^2 = 17^2

(x +9) ^2 + (y +7)^2 = 17^2

(x +9) ^2 + (y +7)^2 = 289
