Answer:

A

Step-by-step explanation:

Hello!

When given an equation y=mx+b, m stands for the slope and b stands for the y-intercept. The y-intercept tells us that even if we start on the x value 0, whatever is the y-intercept will be our answer.

For this equation, the 20 does not represent per hour rental, as it should be the slope if it was. The total cost is not true either, 20 would be placed where the Y is.

It is A, since no matter how many hours you rent the kayak, it will still be a 20 dollar deposit.

Question 1 Answer:

Aunt 1 and Grandma 1 would fill gift bags.

Mom and Aunt 2 would make centerpieces.

You and Grandma 2 would blow up balloons.

Since you are pairing up to complete the tasks, these pairs each have the shortest times in their respective categories and therefore are the most logical pairing to complete tasks.

Question 2 Answer:

We use algebra and our previous pairings to determine the length of each task.

<u>Gifts Bags --> 6/7 hours</u>

x = time together

\frac{1}{x} = rate of completion

Aunt 1 = \frac{1}{1.5} Grandma 1 = \frac{1}{2}

\frac{2}{3} +\frac{1}{2} = \frac{1}{x}

\frac{7}{6} = \frac{1}{x}

x = \frac{6}{7}

<u>Centerpieces --> 7/4 hours</u>

x = time together    \frac{1}{x} = rate of completion

Mom = \frac{1}{3.5} Aunt 2 = \frac{1}{3.5}

\frac{2}{7} + \frac{2}{7}  = \frac{1}{x}

\frac{4}{7} = \frac{1}{x}

x = \frac{7}{4}

<u>Balloons --> 15/16 hours</u>

x = time together    \frac{1}{x} = rate of completion

You = \frac{1}{1.5} Grandma 2 = \frac{1}{2.5}

\frac{2}{3} + \frac{2}{5}  = \frac{1}{x}

\frac{16}{15} = \frac{1}{x}

x = \frac{15}{16}

Shortest amount of time to complete all tasks is:

\frac{6}{7} + \frac{7}{4} + \frac{15}{16} = \frac{397}{112}  ≈ 3.54 hours

Converting hours to hours and minutes --> 3 hours 32 minutes

Therefore they must arrive by 5:28pm to complete the tasks in time to leave at 9:00pm.

Rewrite in simplest terms: -10(-3m-10)-3(-8m+3) i don't usually ask questions that often but I actually need help this time. so
andreev551 [17]

Answer:

The simplest form is 6m+91.

Step-by-step explanation:

Consider the given information.

-10(-3m-10)-3(-8m+3)

First, remove the parenthesis by multiplying -10 and -3 inside the parenthesis.

30m+100-24m-9

Now, rearrange the like terms.

30m-24m+100-9

Combine the like terms.

6m+91

Hence, the simplest form is 6m+91.

What is the percent of the number 2 in the number 625
Tpy6a [65]
Write 2/625 and then multiply the result by 100%:  200%/625 can be re-written as  8% / 25 by dividing both 200 and 625 by 25.

8% / 25 can be thought of as "eight twenty-fifths of 1 percent.  (ANSWER)

Using my calculator, I found that 2/625 is 0.0032.  Mult. that by 100% results in 0.32.  Note that 8/25 = 0.32.
