DC = 13.4 WHAT IS BD

Abdiel's total if he uses a coupon for 12% off the subtotal and leaves a 25% tip before the discount is $27.46

The correct answer option is option B

Amount of total after discount = 12% × $24.30

= 0.12 ×24.30

= $2.916

Amount of abdiel's tip = 25% × $24.40

= 0.25 × 24.30

= $6.075

Abdiel's total after discount before tip = (Amount of abdiel's tip + Abdiel's subtotal) - Amount of total after discount

= (6.075 + 24.30) - $2.916

= $30.375 - $2.916

= $27.459

Approximately,

$27.46

Therefore, the total amount Abdiel paid after discount before tip is $27.46

Answer:

(10 + 8) - (7 * 2) = x, 4 pounds of birdseed left

Step-by-step explanation:

      For the first part of our equation, we will find the total amount of pounds of seeds among the bags (addition).

      For the next part, we will find out how much of the bird seed is used (subtraction).

      Then, it will equal whatever is left.

(10 + 8) - (7 * 2) = x, x = pounds of bird seed left

      Now, we will solve.

(10 + 8) - (7 * 2) = x

(18) - (14) = x

The exchange rate of US dollars per Australian dollar is 0.72

The exchange rate of Australian dollars per US dollar is 1.39

Exchange rate

Exchange rate is the price of a country's money in relation to another country's money and it is “fixed” when countries use gold or another agreed-upon standard, and each currency is worth a specific measure of the metal or other standard.

Given,

After arriving in Australia, Jason exchanged $750 of US currency for $1,041.67 Australian dollars. Complete the two statements based on this currency exchange.

Here we need to find the exchange rate of US dollars per Australian dollar and Australian dollars per US dollar then round it to the nearest hundredth.

According to the given details,

Total amount in US dollars = $750

Converted amount in Australian dollar = $1,041.67

When we divide the US dollar by the Australian dollar then we get the value of one dollar rate,

=> 750/1041.67

=> 0.719

When we round off it to the nearest hundredth then we get the exchange rate of $1 is 0.72

Similarly, now we have to divide the Australian dollar by the US dollar then we get the value of one dollar rate,

=>  1041.67/750

=> 1.388

When we round off it to the nearest hundredth then we get the exchange rate of $1 is 1.39.

20 amount of 30% salt solution

How to find the salt solution percentage?

Divide the solute's gram weight by the total weight of the solution, then multiply the result by 100 to get the mass/mass percent of the solution. The amount of solute (measured in grams) per milliliter of solution is known as the mass/volume percent.

Let x be the amount of 30% salt solution

Then, 60-x = amount of 15% salt solution

Salt content of the first solution + salt content of second solution = salt content of the mixture

∴ 0.30x + 0.15(60-x) = 0.20*60

The 80,000 BD Villa in Saar Mr. Abbas plans to sell at a 40% profit , with the annual house price growth rate of 7% (compounded) gives the number of years Mr. Abbas has to wait as approximately 5 years

The growth rate is the rate at which the value changes within a specified period.  

The amount Mr. Abbas bought the Villar in Saar = 80,000 BD

The profit at which he intends to sell it = 40% = 0.4

The rate at which the house prices rise on average = 7 % per annum

Answer:

  2.  $19,547.04

  3.  $10,276.54

  4.  $16,758.38

Step-by-step explanation:

You have three problems in compound interest with different initial payments, interest rates, and compounding intervals. You want the relationship between the initial payment and the future value.

The multiplier of a single payment earning annual interest rate r compounded n times per year for t years is ...

  k = (1 +r/n)^(nt)

For this problem, r=0.09, n=1, t=9. The multiplier of the payment is ...

  k = (1 +0.09/1)^(1·9) = 1.09^9 = 2.17189328

Then the future value of $9000 will be ...

  FV = $9000 × 2.17189328 ≈ $19,547.04

For this problem, r=0.10, n=12, t=4. The multiplier of the payment is ...

  k = (1 +0.10/12)^(12·4) = 1.08333...^48 = 1.48935410

Then the future value of $6900 will be ...

  FV = $6900 × 1.48935410 ≈ $10,276.54

For this problem, r=0.13, n=12, t=13. The multiplier of the payment is ...

  k = (1 +0.13/12)^(12·13) = 1.0108333...^156 = 5.3704484

Then the payment that gives a future value of $90,000 will be ...

  P = $90,000/5.3704484 = $16,758.38

For the spreadsheet calculation, we used the "Goal Seek" capability to adjust the value of cell F4 to 90000 by changing the value in cell B4.

We could have calculated the multiplier as above, then used it different ways for the different problems. Instead, we used one FV( ) function for all of the problems.

Jim has 65 coins in his pocket. All of the coins are nickels and dimes. If the total value of his coins is $5.10, how many nickels or dimes does he have?

nickels = n

dimes = d

We use:

d + n = 65

0.10d + 0.05n = 5.10

solve for d:

d + n = 65

d + n - n = 65 - n

d = 65 - n

substitute in for the second equation: d = 65 - n

0.10(65 - n) + 0.05n = 5.10

6.5 - 0.10n + 0.05n = 5.10

6.5 - 0.05n = 5.10

6.5 - 0.05n - 6.5 = 5.10 - 6.5

- 0.05n= -1.4

n = 28

so there are 28 nickels

Now, solve for d: when n = 28

d + n = 65

d + 28 = 65

d = 37

so there are 37 dimes

Jim has 28 nickels and 37 dimes in his pocket. which is determined by the substitution method.

The term "equation" refers to mathematical statements that have at least two terms with variables or integers that are equal.

Let the number of nickels would be n

Let the number of dimes would be d

As per the given question,

d + n = 65  ....(i)

0.10d + 0.05n = 5.10  ....(ii)

From equation (i),

d + n = 65

d + n - n = 65 - n

d = 65 - n

Substitute in for the equation(ii): d = 65 - n

0.10(65 - n) + 0.05n = 5.10

6.5 - 0.10n + 0.05n = 5.10

6.5 - 0.05n = 5.10

6.5 - 0.05n - 6.5 = 5.10 - 6.5

- 0.05n = -1.4

n = 28

This means there are 28 nickels

Substitute the value of n = 28 in the equation (i),

d + n = 65

d + 28 = 65

d = 37

So there are 37 dimes

Thus, Jim has 28 nickels and 37 dimes in his pocket.

In the given triangle JKL,

M, N ,O are the mid-points of the side JK, JL, KL of the triangle respectively.

Measure of NO is equal to 26 units

Measure of JK is equal to (7x + 17) units

Using mid- point theorem we have,

In triangle JKL,

NO is half the measure of opposite side JK

NO = 1/2 ( JK)

⇒ 26 = 1/2 ( 7x + 17 )

⇒ 7x + 17 = 26 × 2

⇒ 7x + 17 = 52

⇒ 7x = 52 - 17

Cost of goods sold       $332          $191                $268.60

FIFO (First-in, First-out) is based on the assumption that the physical flow of goods sold depends on the chronological order of acquisition.

LIFO (Last-in, First-out) assumes that the cost of goods sold should be based on the latest inventory purchases.

The weighted-average method uses the average cost of goods to determine both the ending inventory and the cost of goods sold.

LIFO:

Ending inventory = $704 ($48 + $264 + 28 x $14)

Cost of goods sold = $332 ($1,036 - $704)

FIFO:

Ending inventory = $845 (11 x $11 + 30 x $14 + 19 x $16)

Cost of goods sold = $191 ($1,036 - $845)

Answer:

Depends on the gravitational force. On Earth, one pound equals 4.41N.

Step-by-step explanation:

The formula for Newton's Second Law of Motion is F=ma, which is Force = mass × acceleration.

The SI unit of mass is the kilogram (kg), so we'll have to convert one pound to kilograms. For practical purposes, one pound equals 0.45kg.

The gravitational force of the Earth is 9.8m/s^2. It is worth noting that each planetary body has its own gravitational force in respect to its mass.

Force = mass × acceleration = 0.45kg × 9.8m/s^2 = 4.41N

This number is only applicable on Earth, and may and will change on a planetary body with a mass different from Earth's.

It would take Amanda 2.25 hours to catch up with Ben

Speed is the ratio of distance to time. It is given by:

Speed = distance/time

Given that Ben covers a distance d at time t, hence:

3 = d/t

d = 3t

Since Amanda leaves One and a half hours (1.5) after Ben leaves, hence Time = t - 1.5

5 = d/(t - 1.5)

d = 5t - 7.5

Since they catch up, hence:

3t = 5t - 7.5

2t = 7.5

t = 3.75 hours

Time for Amanda = t - 1.5 = 3.75 - 1.5 = 2.25 hours
