Answer:

when you ask multiple questions at once, it feels more like i'm doing your HW for you, not that i'm  helping you understand , i'll answer these but you really should have been able to do these if you really did all the others.  Did you just get tired out?  Why can't you do 4, 6, 8?  what is it that you don't understand?

Step-by-step explanation:

4)   old price = 120   to new price = 240

they ask what is the percent change

How much is the change ( in amount )

the "How much is obvious right?  Old price 120 , new price 240.. change is $120

the percent is   change / old price = 120 / 120  = 1  and to put it in percent , multiply by 100 , so 100 % change

6) old price = 250   amount of change -100

so what percent of 250 is 100  

100 / 250 = 0.4   to get it in percent multiply by 100  = 40%

  old price + change = new price

250 +  ( -100)  =  150   new price is $150

8) 5% mark up  , amount of change = $2.50

so 5% of what = 2.50 ?

X* 5% = 2.5

X* 0.05 = 2.5

X=2.5/0.05

X= $50  was the old price

old price + amount change = new price

50 + 2.50 = 52.50

$52.50 is the new price

The simplified form of the expression 4x(x + 1) − (3x − 8)(x + 4) is -3x^2 - 4x - 32.

To simplify the expression 4x(x + 1) − (3x − 8)(x + 4), we can expand the parentheses and combine like terms.

Expanding the first term, we get 4x^2 + 4x.

Expanding the second term, we have -(3x)(x) - (3x)(4) - (-8)(x) - (-8)(4), which simplifies to -3x^2 - 12x - (-8x) - (-32), further simplifying to -3x^2 - 12x + 8x - 32.

Combining like terms, we obtain -3x^2 - 4x - 32.

With the area of the square wall is 87.5 ft^2, the approximate length of each side of the square is 9.35 feet, rounded to the nearest tenth.

To find the length of each side of the square, we need to use the formula for the area of a square, which is A = s^2, where A is the area and s is the length of each side.

In this problem, we know that the area of the square wall is 87.5 ft^2. So we can write:

87.5 = s^2

To solve for s, we need to take the square root of both sides of the equation:

√87.5 = s

Using a calculator, we get:

s ≈ 9.3541

We can check our answer by calculating the area of the square with this length:

9.3541^2 ≈ 87.5

The result the given area of 87.5 ft^2, which confirms that our answer is reasonable.

The probability of getting a black card and a numbered card is 9/26.

To calculate the probability of getting a black card (E1), we need to determine the number of black cards in a standard deck of 52 cards.

There are 26 black cards in total, which consist of 13 spades (black) and 13 clubs (black).

Therefore, the probability of drawing a black card (P(E1)) is:

P(E1) = Number of favorable outcomes / Total number of possible outcomes

P(E1) = 26 / 52

Simplifying this fraction, we get:

P(E1) = 1/2

So the probability of drawing a black card is 1/2.

To calculate the probability of drawing a numbered card (E2), we need to determine the number of numbered cards (2 through 10) in a standard deck.

Each suit (spades, hearts, diamonds, clubs) contains one card for each numbered value from 2 to 10, totaling 9 numbered cards per suit.

Therefore, the probability of drawing a numbered card (P(E2)) is:

P(E2) = Number of favorable outcomes / Total number of possible outcomes

P(E2) = 36 / 52

Simplifying this fraction, we get:

P(E2) = 9/13

So the probability of drawing a numbered card is 9/13.

To calculate the probability of both events occurring together (getting a black card and a numbered card), we multiply the individual probabilities:

P(E1 ∩ E2) = P(E1) × P(E2)

P(E1 ∩ E2) = (1/2) × (9/13)

Simplifying this fraction, we get:

P(E1 ∩ E2) = 9/26

Therefore, the probability of getting a black card and a numbered card is 9/26.

Answer:

$1984.80

Step-by-step explanation:

165.40 times 12 equals 1984.80

Answer:

He pays $1984.80 on his loan in one year.

Step-by-step explanation:

If he pays 165.40 per month, and there are 12 months in one year, then we must multiply the values together.

165.4*12 = 1984.8

He pays $1984.80 on his loan in one year.

The amount in the account at the end of 1 year is $5400.

The amount in the account at the end of 2 year is $5832.

What do you mean by interest rate?

The real yearly cost of funds over the course of a loan is the annual rate that is charged for borrowing (or made by investing), expressed as a single percentage number.

According to data in the given question,

We have:

Deandre places $5000 in an account that pays 8% interest compounded each year.

And no withdrawals are made from the account.

Now, we need to determine the amount of 8% interest on the $5000,

\(=\frac{5000}{100}*8\\ =400\)

Then, the amount in the account at the end of 1 year =$5000+$400

=$5400.

Now, we need to determine the amount of 8% interest on the $5400,

\(=\frac{5400}{100}*8\\ =432\)

So, the amount in the account at the end of 2 year =$5400+$432

=$5832.

18,792 you round to the thousand which is 8 and the number after is 7 which is above 5 so the 8 turns into a 9

Answer:

19000

Step-by-step explanation:

18,792

Rounding to the nearest thousand

The 8 is in the thousands place

We look at the number in the hundreds place, 7

It is 5 or higher so we will round the 8 up to 9 and everything else to the right will become zeros

18,792 becomes 19000

To find how many degrees a polygon's angles add up to, use the formula (n - 2) · 180, where n = the number of angles. So, since this polygon has 5 angles (it's a pentagon)

(5-2) · 180 = 3 · 180 = 540.

Now, all we have to do is add up all of the angles:

75 + 126 + 126 + 81 + c = 540

c = 132

The width of the canyon in the given image is 70 ft wide.

To find the width of the canyon, we can visually extend side DC and AE to form two sides of a rectangle.

Given that side DC is the same as side AE (80 ft), we can use this same reasoning to determine that the width is the sum of side AB and side BC, which is 35 + 35.

This gives us a width of 70 ft.

In a rectangle, the longer side is known as the length and the shorter side is known as the width.

Therefore, using the sum of side AB and side BC, we get a width of 70 ft for the canyon.

The probability that the number is an even number is 1/2.

The probability is defined as the ratio of number of favourable outcomes and the the total number of possible outcome.

A number from 8 to 15 is drawn at random.

The number between 8 to 15 are 8, 9, 10, 11, 12, 13, 14, 15 = 8

Total even number = 8, 10, 12, 14 = 4
