Answer:

7:30

Step-by-step explanation:

Half past 5 would be 5:30.

An hour is 60 minutes, half of 60 is 30

In order to find the time two hours later we must add 2 to 5:30

5:30+2=7:30

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:

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

Y – x² = 4.5 and y = x^4

8090 [49]

Linear functions are in the form y=mx+b.

But the functions are in the form of y=x^4 and y-x^2=4.5.
Their exponents make them a quadratic function so it doesn't have the same rate of change. Therefore the equations are not linear. They are quadratic.

Marilyn knows that she needs $45,000 for a down payment on a house. She found an investment that earns 3.15% interest compoundin

laila [671]

She should save $38,450.39.

The formula for the amount of money in an interest-bearing account that is compounded is

$A=p(1+\frac{r}{n})^{nt}$

where A is the total amount in the account, p is the amount of principal invested, r is the interest rate as a decimal number, n is the number of times per year interest is compounded, and t is the number of years. Using our information we have:

$45000=p(1+\frac{0.0315}{12})^{12\times5}
\\
\\45000=p(1.002625)^{60}$

Divide both sides:
$\frac{45000}{1.002625^{60}}=\frac{p(1.002625)^{60}}{1.002625^{60}}
\\
\\38450.39=p$

The fare for a taxi cab is $2.50 per passenger and $0.75 for each mile. A group of friends has $22.00

xeze [42]

For this case we have to:

x: Let the variable representing the number of people to travel in the group

y: Let the variable representing the number of miles traveled.

If friends only have $22 then we have the following inequality:

$2.50x + 0.75y \leq22$
