Treat it as a normal equation - except that you have to add fractions as coefficients rather than integers.Improper fractions will probably be best for adding because later you can cross multiply.

A bag contains 10 red chips, 8 white, 6 blue, and 8 yellow. You randomly pick one chip from the bag. Without replacing the chip, you randomly pick a second chip. Find the probability of choosing the first chip, then the second chip.1. Red and yellow
2. Yellow and blue
3. Blue and blue
4. White and yellow
5. Not white and not white
6. Blue and not red

Answers

number choice 1, like Red and yellow. you have to find the color chips with the highest numbers and then use strikethrough.

Given a = 4, b = -2 and c = 8, evaluate 3abc.

Answers

3(4)(-2)(8) is what the equation looks like all you have to do is multiply all these numbers so 3 times 4 equals 12 and 12 times -2 equals -24 then lastly multiply -24 by 8 which gives you the product of -192.

-192 is the answer. you get this by multipling 3 times 4 times 8 times -2.

Find the angular velocity in radians per second of a wheel turning at 25 revolutions per minute.

Answers

(25 rev/minute) x (2 pi radian/rev) x ( minute / 60 sec) = 2.618 rad/sec (rounded)

1 revolution= 2π radians= 6,28 radian
1 minute= 60 s
25 rev=50π=157 radian

$(25)/(1)* (6,28)/(60)=2,62 (rad)/(s)$

the alabama river is 729 miles. if 1 mile equals 1.61 kilometers, find the length of the river to the nearest whole kilometer. (due tomorrow)

Answers

1 times 729=729 so

1mile=1.61kiloneter
multiply both sides by 729 to get 729 miles on left side
729 miles=1173.69 kilometer

whole
1173.6
6>5 so round up
1174

answer is 1174 kilometer

A bowling alley charges each person $6 to play a game and $4.50 to rent a pair of bowling shoes. Write an expression to show how much the bowling alley will charge f friends if they each play 3 games and all but one of them rents shoes.

Answers

Write an expression to show how much the bowling alley

cost = f($6 x 3) + (f - 1) x $4.50

c=9f+4.5*(f-1)

Final answer:

The expression to calculate the total cost for f friends playing 3 games each, with all but one renting shoes, is 6 * 3 * (f - 1) + 4.50 * (f - 1).

Explanation:

To calculate the total cost for f friends playing 3 games each, all but one renting shoes, we can write the expression: 6 * 3 * (f - 1) + 4.50 * (f - 1). The cost of each game is $6, and since each person plays 3 games, we multiply that by 3. The cost of renting shoes is $4.50, and since all but one person rents shoes, we multiply that by (f - 1).
