Ron takes a ribbon thats 48inches long and cuts it in 2pcs, how long is each pcs, 1 pc is 3times as the other how long is each pcs.

Answers

Answer 1
Answer: 48/4 because it is 3 times as long as the other piece thinking there are 4 pieces. So one piece has to be 12 because 48/4 is 12 and 12 x 3 is 36 so then we double check 12+36=48 so the pieces are 12inc and 36inc

A scientist needs 10 litera of a 20% acid solution for an experiment but she has only 5% solution and a 40% solution. To the nearest tenth of a liter, how many liters of the 5% and the 40% solutions should she mix to get the solution she needs?

Answers

x = liters of 5% solution

y = liters of 40% solution

The scientist wants 10 L total of a 20% solution, so

x + y = 10

0.05 x + 0.40 y = 0.20 (x + y) = 2

From the first equation,

y = 10 - x

Substitute this into the second equation and solve for x :

0.05 x + 0.40 (10 - x) = 2

0.05 x + 4 - 0.40 x = 2

2 = 0.35 x

x ≈ 5.714 L

Solve for y :

y = 10 - x

y ≈ 4.286 L

range is the set of number you get from inputing the domain
normally domain is x and range is y
(x,y)

domain is all 1st number
range is all 2nd numbers

doman={-5,-3,0,3}
range={5,2,3} (if it repeats, don't list)

5! Means 5 factorials >> 5 x 4 x 3 x 2 x 1 It's simply just the product of a series of descending natural numbers (no negative numbers or fractions) which are indicated by an exclamation point.
The answer is B. because 5x4= 20, 20x3 (next number to multiply in the series) =60, 60x2= 120, 120x1= 120.
