Which expression can be used to convert 22 Australian dollars to US dollars?Assume 1.2 Australian dollars equals 1 US dollar.

Answers

Answer:

Expression used to convert 22 Australian Dollar to US Dollar is (22)/(1.2)

Step-by-step explanation:

Given:

22 Australian Dollars.

To Do: Expression which can be used to convert Australian dollar to Us dollar.

Let, x be the number of Australian Dollars and y be the US Dollars.

We know that 1.2 Australian Dollar equal to 1 US Dollar.

⇒ 1 Australian Dollar = (1)/(1.2)  US Dollar

So, x Australian Dollar = (1)/(1.2)* x\:=\:(x)/(1.2)  US Dollar

Thus, Expression that can be used to convert Australian Dollar into US Dollar is given by,

y=(x)/(1.2)

So. 22 Australian Dollar

put x = 22

y=(22)/(1.2)=18.3 US Dollars

Therefore, Expression used to convert 22 Australian Dollar to US Dollar is (22)/(1.2)

1.2(22)=x
x= US Dollar amount of 22 Australian dollars.

The revenue, in dollars, of a company that makes toy cars can be modeled by the polynomial 3x2 + 4x – 60. The cost, in dollars, of producing the toy cars can be modeled by 3x2 – x + 200. The number of toy cars sold is represented by x.If the profit is the difference between the revenue and the cost, what expression represents the profit?

3x – 260
3x + 140
5x – 260
5x + 140

Answers

For this case we have the following quadratic functions:

Revenue:

Cost:

Then, we observe that the profit is given by the following mathematical relationship:

Substituting values we have:

Making the corresponding calculations we have:

Answer:

An expression that represents the profit is:

Profit = 5x - 260

Answer:

5x – 260

Lena is making two dishes for an event. Each batch of her mac-n-cheese recipe calls for 6 ounces of cheese and 2 tablespoons of basil. For every two pizzas, she needs 16 ounces of cheese and 5 tablespoons of basil. Part A) Lena buys a 32-oz package of cheese. Does she have enough cheese to make 2 batches of man-n-cheese and 3 pizzas?

Answers

no she needs four more ounces of cheese to make 2 batches of mac n cheese and 3 pizzas

Final answer:

To make 2 batches of mac-n-cheese and 3 pizzas, Lena needs a total of 60 ounces of cheese. If she only buys a 32-ounce package of cheese, she does not have enough.

Explanation:

To determine if Lena has enough cheese to make 2 batches of mac-n-cheese and 3 pizzas, we need to calculate the total amount of cheese needed for each dish. Each batch of mac-n-cheese requires 6 ounces of cheese, so 2 batches would require 2 x 6 = 12 ounces of cheese. Each pizza requires 16 ounces of cheese, so 3 pizzas would require 3 x 16 = 48 ounces of cheese. Therefore, the total amount of cheese needed is 12 + 48 = 60 ounces.

If Lena buys a 32-ounce package of cheese, she does not have enough cheese to make both the mac-n-cheese and the pizzas. The 32-ounce package is smaller than the total amount of cheese needed, which is 60 ounces. Therefore, Lena would need to buymore cheese.

The value of a car depreciates by 18% per year. Work out the current value of a car bought 4 years ago for £20000

Answers

Given:
depreciation rate: 18%
Value of the car : 20,000
Age of the car : 4 years.

The depreciation is based on the current value of the car. Therefore, the amount of depreciation varies.

yr   Beginning Value   Dep. Rate    Depreciation      Ending Value
1   20,000.00                 18%             3,600.00          16,400.00
2   16,400.00                 18%             2,952.00          13,448.00
3   13,448.00                 18%             2,420.64          11,027.36
4   11,027.36                 18%             1,984.92            9,042.44

The current value of a car bought 4 years ago is 9,042.44

Beginning value : purchased amount on 1st year. then, ending balance of the previous year from 2nd year onwards.
Depreciation : Beginning value * depreciation rate
Ending value : Beginning value - depreciation

20000 = 100%18 x 4 = 72%20000 / 100 = 200200 = 1%200 x 72 = 14,40020000 - 14,400 = 5600The value of it now should be £5600
