Part of the proceeds from a garage sale was ​$440 worth of ​$10 and ​$20 bills. If there were 2 more ​$10 bills than ​$20 ​bills
Korvikt [17]

Hey there! I'm happy to help!

Let's set this up a system of equations where x represents the number of 10 dollar bills and y represents the number of 20 dollar bills.

10x+20y=440

x=y+2

We see that x has a value of y+2, so we can replace the x in the first equation with y+2 so we can solve for y.

10(y+2)+20y=440

We use distributive property to undo the parentheses.

10y+20+20y=440

We combine like terms.

30y+20=440

We subtract 20 from both sides.

30y=420

y=14

Since there are 2 more $10 bills, there would be 16 of those.

Therefore, there are 16 $10 bills and 14 $20 bills.

Have a wonderful day! :D

4. In the game Scrabble, there are a total of 100 tiles. Of the 100 tiles, 42 tiles have the vowels A, E, I, O, and U printed on
Nonamiya [84]

Answer:

Step-by-step explanation:

Given that in the game Scrabble, there are a total of 100 tiles. Of the 100 tiles, 42 tiles have the vowels A, E, I, O, and U printed on them, 56 tiles have the consonants printed on them, and 2 tiles  are left blank.

a. If tiles are selected at random, the probability that the first tile drawn from the pile of 100 tiles is a vowel = \frac{42}{100} =0.42

b. If tiles drawn are not replaced,  the probability that the first two tiles selected are both vowels =0.42^2 = 0.1764

c. Event A is drawing a vowel, event B is drawing a consonant, and event C is drawing a blank tile. A1 means a vowel is drawn on the first selection, B2 means a consonant is  drawn on the second selection, and C2 means a blank tile is drawn on the second selection. Tiles are selected at random and without replacement.

i. Find P(A1 and B2). =\frac{42}{100} *\frac{56}{99} \\=0.2376

ii. Find P(A1 and c2). =\frac{42}{100} *\frac{4}{99} \\=0.0170

iii. Find P(A1 and A2).=\frac{42}{100} *\frac{41}{99} \\=0.1739

Please help! I would really appreciate it!
Jlenok [28]
Hello!

First you have to find what percent like action movies with the data you have

You add all the numbers up

80 + 160 + 200 + 360 = 800

Now you divide the amount that like action by the total amount of people that answered

160 / 800 = 0.2

Now you multiply this by 3200 to see how many would say action

3200 * 0.2 = 640

The answer is 640

Hope this helps!
