So you have 10 total cups and 5 batches. Assuming that the raisens are evenly distributed, you get 10/5, which is 2 raisin cups per batch

Please help!! will mark branliest

Answer:

a. After the first bounce, the ball will be at 85% of 8 ft. After 2 bounces, it'll be at 85% of 85% of 8 feet. After 3 bounces, it'll be at (85% of) (85% of) (85% of 8 feet).  You can see where this is going. After n bounces the ball will be at

h(n) = (85\%)^n 6ft = (\frac{17}{20})^n(6ft\times 12\frac{in}{ft}) = (\frac{17}{20})^n\times72'

b. After 8 bounces we can apply the previous formula with n = 8 to get

h(8)=(\frac{17}{20})^8\times 72' = 19.62'

c. The solution to this point requires using exponential and logarithm equations; a more basic way would be trial and error using the previous h(n)increasing the value of n until we find a good value. I recommend using a spreadsheet for that; the condition will lead to the following inequality:

1>(\frac{17}{20})^n\times 72 Let's first isolate the fraction by dividing by 72.

(\frac{17}{20})^n  Now, to get numbers we can plug in a calculator, let's take the natural logarithm of both sides:

ln ((\frac{17}{20})^n) < ln \frac 1{72} \rightarrow n\times ln (\frac{17}{20}) < -ln72. Now the two quantities are known - or easy to get with any calculator, replacing them and solving for n we get:

-(0.16)n < - 4.27 \rightarrow n>26.31 Now, since n is an integer - you can't have a fraction of a bounce after all, you pick the integer right after that, or n>27.

Who think they can figure out this equation for me
Vaselesa [24]

Answer:

b < -1

Step-by-step explanation:

Step 1: Write inequality

-3(6b - 1) > 18 - 3b

Step 2: Solve for <em>b</em>

<u>Distribute -3:</u> -18b + 3 > 18 - 3b

<u>Add 18b to both sides:</u> 3 > 18 + 15b

<u>Subtract 18 on both sides:</u> -15 > 15b

<u>Divide both sides by 15:</u> -1 > b

<u>Rewrite:</u> b < -1
