wilma buys a new game that is priced $43.89. she gets successive discounts of 15% followed by 5% off on the game. the purchase price of wilma’s game is

Answers

If you would like to know the purchase price of Wilma's game, you can calculate this using the following steps:

15% of $43.89 = 15% * 43.89 = 15/100 * 43.89 = $6.5835 = $6.58

$43.89 - $6.58 = $37.31

5% of $37.31 = 5% * 37.31 = 5/100 * 37.31 = $1.8655 = $1.87

$37.31 - $1.87 = $35.44

The correct result would be $35.44.

Answer: C 80.75%

Step-by-step explanation:

Which is bigger:
3/8 or 0.38.
Can you tell me how to work it out?please!

Answers

You do 3 x 8 / 100 to work out 3/8 as a decimal. So its 0.24. 0.38 is bigger

A bowl contains 4 red marbles and 3 yellow marbles. Tim randomly draws 3 red marbles from the bowl. He replaces each marble after it is drawn. What is the probability that he draws 2 yellow and 1 red?

Answers

So,

The probability of drawing a yellow marble is (3)/(7).
Since he replaces the marble after it is drawn out, the probability of drawing another yellow is the same: (3)/(7).

The probability of drawing a red marble is (4)/(7).

In order to get the probability of drawing 2 yellow marbles and 1 red marble, given that each marble is replaced after it is drawn out, we must multiply the fractions together.

( (3)/(7) )( (3)/(7) )( (4)/(7) ) = (36)/(343)

Because the order of the marbles doesn't matter, we will multiply the probability by 3.
3( (36)/(343) ) = (108)/(343)

Isolate c
a=b(1/c-1/d)

Answers

A= b(1/c - 1/d)
A/b = 1/c -1/d
A/b + 1/d = 1/c
(A/b + 1/d) 1 = c

Answer: c = b/(a + 1).

Step-by-step explanation:

a = b(1/c - 1/d)

Expand RHS by first finding LCM

a = b((d — c)/cd)

a = (bd — bc)/cd

Then cross multiply

acd = bd — cd

Collect the terms having c to the LHS

acd + cd = bd

Factorise cd out of LHS

( a+ 1)dc = bd

c = bd/(a + 1)d

c = b/(a + 1).
