A clothing store offers a 30% discount on all items at the store. If the original price of a sweater is $40, how much will you pay for the sweater at the discounted price?

Answers

Answer:

x=1

Step-by-step explanation:

30% = .30 or .3

$40(.3)= 12

$12 is how much money you saved. So now just subtract 40-12.

$40-12= $28

The sweater will cost $28 dollars at discounted price.

A group of friends wants to go to the amusement park. They have no more than $245
to spend on parking and admission. Parking is $9.25, and tickets cost $25.75 per
person, including tax. Which inequality can be used to determine p, the maximum number of people who can go to the amusement park?

Answers

Answer:

9.25 + 25.75p ≤ 245

Step-by-step explanation:

I didn't see any inequality options to select from . . .

245 ≤ 9.25 + 25.75p

p= number of people

since there’s no more than $245, they can only spend the exact amount or less than which is why ≤ (less than or equal) to is used.

x = -2

y = 9

Step-by-step explanation:

y = -3x + 3

y = 5x + 19

We can put one y as another:

-3x + 3 = 5x + 19

-8x = 16

x = -2

And now let's check using x = -2

y = (-3 * -2) + 3

y = (5 * -2) + 19

y = 6 + 3

y = -10 + 19

y = 9

y = 9

Dillon peeled 40 pounds of potatoes. How many ounces of potatoes did Dillon peel?

Answers

Answer:

640

Step-by-step explanation:

40 pounds = 640 ounces

The ounces of potatoes that Dillon peeled is 640 ounces.

What is Unit Conversion?

Unit conversion is defined as expressing the same quantity by different measurement units.

For example, a distance of 20 meter can be also expressed as 2000 cm. The distance is same.

Given that,

Amount of potatoes that Dillon peeled = 40 pounds

We have to convert the same amount of potatoes in to the measurement unit of ounces.

We have to convert the unit.

We have the measurement unit that,

1 pound = 16 ounces

40 pounds = 40 × 16 = 640 ounces

Hence 640 ounces of potatoes did Dillon peel.

Amanda and Carly have the same percentage of green marbles in their bags of marbles. Amanda has 4 green marbles and 16 total marbles. Carly has 10 green marbles. How many of Carly's marbles are NOT green?​

Answers

Answer:

30

Step-by-step explanation:

They both have the same percentage of green marbles, Amanda has 16 total marbles, 4 of them are green. So 25 percent of her marbles are green. If 25 percent of Amandas marbles are green, 25 % of Carlys marbles are green too. Carly has 10 green marbles, if 10 is 25 percent of the total amount then the total amount if 40, minus 10 from 40 because we only want the non green ones and the answer is 30. :)

You invest $7000 in an account bearing 5% interest for ten years. A. How much will the account be worth if compounded quarterly? What about monthly? Daily? B. What do you notice about the amount of additional money you make as the frequency of compounding increases?

Answers

Answer:quarterly, monthly, daily

Step-by-step explanation:

quarterly: y=7000 (1+.05/4)'10(4)     answer y=11,505.34

monthly: y=7000 (1+.05/12)'10(12)    answer y=11,529.07

daily: y=7000 (1+.05/365)'10(365)    answer y=11,540.65

What do you notice about the amount of additional money you make as the frequency of compounding increases? The account is worth more

The account will be worth approximately $11,505 if compounded quarterly.

The account will also be worth approximately $11,540 if compounded daily.

A. Compounded quarterly:

n = 4 (quarterly compounding)

A = 7000(1 + 0.05/4[tex])^{(4)(10)[/tex]

A ≈ 7000(1.0125)⁴⁰

A ≈ 7000 x 1.643619463

A ≈ 11505.34

The account will be worth approximately $11,505 if compounded quarterly.

B. Compounded monthly:

n = 12 (monthly compounding)

A = 7000(1 + 0.05/12[tex])^{(12)(10)[/tex]

A ≈ 7000(1.00416666667)^(120)

A ≈ 7000 x 1.6487212707

A ≈ 11540.05

The account will be worth approximately $11,540 if compounded monthly.

C. Compounded daily:

n = 365 (daily compounding)

A = 7000(1 + 0.05/365)^(365*10)

A ≈ 7000(1.0001369863)^(3650)

A ≈ 7000 * 1.6487212707

A ≈ 11540.05

The account will also be worth approximately $11,540 if compounded daily.

B. As the frequency of compounding increases, the additional money earned (compared to simple interest) becomes more significant. In this case, regardless of whether the interest is compounded quarterly, monthly, or daily, the resulting values are very close to each other.

Answer:

81/x - 3 = 6 2x - 3 = 15

Answer:

it's only the last two

Step-by-step explanation:

3x + 2 = 25

3x + 2 - 2 = 3x

25 - 2 = 23

3x = 23

3x / 3 = x

23 / 3 = 7 2/3

x = 7 2/3 not this one

x/3 + 7 = 8

x/3 + 7 - 7 = x/3

8 - 7 = 1

x/3 = 1

x/3 * 3 = x

1 * 3 = 3

x = 3 not this one

4 + 5x = 18

4 + 5x - 4 = 5x

18 - 4 = 14

5x = 14

5x / 5 = x

14 / 5 = 2 4/5 not this one

24 - 2x = 13

24 - 2x - 24 = -2x

13 - 24 = -11

-2x = -11

-2x / -2 = x

-11 / -2 = 5 1/2 not this one

81/x - 3 = 6

81x - 3 + 3 = 81/x

6 + 3 = 9

81/x = 9

81/x * x = 81

9 * x = 9x

81 = 9x

81 / 9 = 9

9x / 9 = x

9 = x this one

2x - 3 = 15

2x - 3 + 3 = 2x

15 + 3 = 18

2x = 18

2x / 2 = x

18 / 2 = 9

x = 9 this one
