For the first question you shade in the bar to the 20% mark as she has saved 20% of the money needed for her jacket. To complete the bar you add the amount of how much each percentage is in dollars. We know 20%=$15 and the percentage goes up 20% each time so you keep adding $15 on. For question 2 the bar is half way between 0 and 20 and half of 20 is 10. As 10 is half of 20 we half 15 to get $7.50

r-ruslan [8.4K]
You just have to rearrange the formula.
So:
765 = 135 x m + 225
765 - 225 = 135 x m
540 = 135 x m
m = 540 / 135
m = 4

So four months.

Can you guys help please will mark brainliest answer.I need help on 24 and 28

24) All percents are numbers with the decimal moved 2 to the right. So if you have 275%, move the decimal to the left twice to get a factor of 2.75. that means that the puppy is 2.75 times heavier at 4 months than it was at 2 months. Since you need the answer as a mixed fraction, your answer is;
2.75=2+\frac{3}{4}=2~\frac{3}{4}

28) If 6 of 75 trees are 30+ feet tall and you need to know how many are under, subtract 6 from 75 to get (75 - 6) = 69 trees under 30ft tall.
You're looking for the percent of trees under 30ft tall, so divide the number of trees <30ft by the total number of trees to get;
\frac{69}{75}= .92
Move the decimal 2 to the right to get 92%.
Your answer is that 92% of trees is under 30ft.

Which expression can be expanded using the binomial theorem?
kirill [66]

Answer:

The third choice:  (x² - 1)³

Step-by-step explanation:

That is the only expression that is a binomial.  Binomial means "two numbers".  For this expression, x² is one number, and -1 is the other.  Choice 1 is a monomial (one number) and choices 2 and 4 are trinomials (three numbers)
