Solve the equation r+11+8r=29

Answers

Answer 1

Answer: Combine like terms: r+8r=9r. subtract 11 from both sides 9r=18. r=2

Answer 2

Answer: Ok so lets evaluate this equation. First,we have to combine like terms which in this case us r only. So lets do it r+8r is simply 9r+11=29 so now since we want to isolate or in other terms get r the variable by itself we would have to subtract 11 form both sides. 29 -11 is simply 18 now we have 9r=18 divide 9 on both sides and r is equal to 2

Nishi, who has a 70% free-throw percentage, is in a two-attempt free-throw situation. This means she will attempt the second free throw no matter what happens on the first. What is the probability of scoring zero points?

Answers

Nishi has a 70% chance of making a free-throw. This means that out of 100%, Nishi will miss the free-throw 30% of the time.

Zero points means that Nishi will have to miss the free-throw twice. To calculate this occurrence, we must multiply the chances of Nishi missing twice.

This occurrence asks for a 30% chance to happen the first free throw, and a 30% chance to happen on the second free throw. Convert the percentages to a decimal:

$30 / 100 = .30$

Multiply these two occurrences together:

$.30 * .30 = 0.09$

Convert this decimal back into a percentage:

$0.09 * 100 = 9$

There is a 9% chance that Nishi will score zero points.

Answer:

9% that is your answer!
