you install 618 feet of fencing along the perimeter of a rectangular yard. The width of the yard is 152 feet. What is the length of the yard?

Answers

Answer:

The length of the yard is 157 feet

Step-by-step explanation:

P= L+L+W+W or 2L+2W. (P is perimeter, L is length, and W is width.)

Substitute in known values for the variables.

618=2L+2(152)

Multiply.

618=2L+304

Now solve for L by doing inverse operations (subtract).

314=2L

Divide.

L=157

So the yard is 157 feet long.

At Trendy Tailor Boutique's annual end-of-season sale, every necktie in the
shop gets marked down. Will purchased 7 neckties during the sale. Each
necktie cost $8 less than its full price. He paid a total of $147.
Which equation can you use to find f, the cost of each necktie at full price?

Answers

By direct calculation, we will see that the full price of each necktie is $29.

How to find the complete price of each necktie?

Let's say that the full price of each necktie is f.

We know that Will each necktie costed $8 less than the full price, so he paid:

(f - $8) for each one.

Knowing that he bought 7 and paid a total of $147, we know that he paid:

$147/7 = $21

Then we need to solve:

(f - $8) = $21

Solving for f, we have:

f = $21 + $8 = $29.

So the full price of each necktie is $29.

ERROR ANALYSIS Describe and correct the error in
graphing and comparing
y= x^2and y = 0.5x^2.

Answers

Answer:

The graph should be stretched rather than become narrower.

Step-by-step explanation:

To figure this out, just create some example points.

At x = 0, your y-value will always be 0. But if you were to plug in the value 1, you would get a y-value of 1 in y=x^2, but a value of 0.5 in y=0.5x^2. If you were to plug in a value of 2, you would get a value of 4 in y=x^2, but a value of 2 in y=0.5x^2.

If you continue this pattern for a few more points, then plot them, you will see that adding a coefficient of 0.5 simply stretches the graph

Emma doesn't have experience using credit cards. In fact, she just got her first one. She is also about to start her first year
of college. She uses her new credit card to purchase textbooks for her classes. The total comes to $300. These are the
terms of her credit card:
• It has a 15% annual interest rate.
• The interest is compounded monthly
• The card has $0 minimum payments for the first four years it is active.
The expression that models this situation is P(1 + r/n)^nt, where (1 + r/n) represents the growth factor of the interest rate.

Answers

Answer:

P = $300

r = 0.15

n = 12

$544.61  (to the nearest cent)

[tex]P(1+r)^t[/tex]

$524.70  (to the nearest cent)

Step-by-step explanation:

P = principal amount = $300

r = annual interest rate in decimal form = 15% = 15/100 = 0.15

n = number of times interest is compounded per unit t = 12

How much she'll owe in 4 years

P = 300

r = 0.15

n = 12

t = 4

[tex]P(1+\frac{r}{n})^{nt}=300(1+\frac{0.15}{12})^{12 \times 4}[/tex]

= $544.61  (to the nearest cent)

Yearly compounding interest rate

[tex]P(1+r)^t[/tex]

How much she'll owe in 4 years at yearly compounding interest

[tex]P(1+r)^t=300(1+0.15)^4[/tex]

Larry claims that (14 + 12) × (8 + 12) and (14 × 12) + (8 × 12) are equivalent because they have the same digits and the same operations. Is Larry correct?

Answers

Answer:

Larry is wrong

Step-by-step explanation:

Multiplying big numbers will give significantly bigger results then multiplying smaller numbers then adding them. 14 + 12 = 26 & 8 + 12 = 20. 14 x 12 = 68 & 8 x 12 = 96. 96 + 168 is alot less then 26 * 20 so that is why larry is wrong
