Monique needs to buy a baseball for $20, a soccer ball for $15, and a set of tennis balls for $12. Monique has a coupon that giv

es her a discount of x percent on a baseball. She has a second coupon that gives her a discount of y percent on a set of tennis balls. The third coupon gives her a discount of z percent on her total purchase. She cannot combine the coupon for the total purchase with the other two coupons. These expressions give both possibilities for the total cost of Monique's purchase after the coupons are applied, the variables represent the percentages as decimals. (1−x)20+(1−y)12+15 (1−z)(20+15+12) Which part of the expression represents the price of the set of tennis balls after a coupon was applied directly to them?

Answer:

12(1 - y) and 12(1- z).

Step-by-step explanation:

Cost of a base ball = $20

Cost of the base ball after a discount coupon of x% = $20 - x% of $20

= $20(1 - x)

Similarly cost of a tennis ball with y% discount = $12(1 - y)

And cost of soccer ball = $15

So the total cost of Monique's purchase = 20(1 - x) + 15 + 12( 1 - y)

Here 12(1 - y) represents the price of the set of tennis balls after coupon z was applied.

If other coupon of z% is applied on total purchase of Monique, then the cost will be = (10 + 15 + 12) - z% of (10 + 15 + 12)

= (10 + 15 + 12)(1 - z)

In this expression 12(1 - z) represents the cost of a pair of tennis balls after z% discount on total purchase.

5.<br> If g(x) = 3x + 4, what is the value of g-1(g(-2))?
stepan [7]

Answer:

- 2

Step-by-step explanation:

The composition of inverse functions gives x

g(x) and g^{-1} (x) are inverse functions, then

g^{-1} (g(x)) = x , thus

g^{-1} (g(- 2)) = - 2

We can find the side length of square 3 by dividing by 4, which is 9.

Then, we find the side length of square 2 by dividing it by 4, which is 12.

To find the AREA of square 1, we do a^2+b^2=c^2. This is basically adding up area of square 1 and square 2 to get square 3.

a^2+b^2=c^2
9^2+12^2=c^2
81+144=225

So the area is 225 units.

Adidea Corp. estimates that $5,670 of its accounts receivables are uncollectible. How will the company record the transaction?
sergiy2304 [10]

Answer:

The transaction will be recorded by the company as :

DR : Non-collectibles $5670  

CR : Accounts receivable $5670

Step-by-step explanation:

Amount of money estimated = $5670

The amount which is non-collectible is recorded as a DEBIT transaction by the company because the amount in the non-collectible account can't be received by the company.

But, the amount in the receivables is the amount which is available for receiving and can be received by the company. So, receivable transaction is marked as CREDIT by the company.

Thus, the transaction will be recorded by the company as :

DR : Non-collectibles $5670  

CR : Accounts receivable $5670
