84 is 30% of what number?
2.8
25.2
280
2520

Answer:

$-108.44

Step-by-step explanation:

Hey! Let's help you out with this question!

We always want to begin with what we know. We know that Jason has $284.31 on his lunch account and that during the year he mowed 13 lawns and earned $30 for each lawn. By the end, he spent $782.75 and now we need to figure out what his balance was at the end of the year. This can be split into 2 parts:

Part 1:

Let's start by how much money he has in total. We can take the current balance in his account of $284.31 and add the amount of money he made mowing lawns. We know that he mowed 13 lawns and earned $30 for each lawn. So, we can just chalk that total to be:

\(13*30=390\)

Based on our calculation, we know that he has earned $390 in total from mowing 13 lawns for $30 each lawn. Now that we have that, let's add that earning into his current balance and that'll give us:

\(284.31+390=674.31\)

Therefore, in total Jason has $674.31. including how much he earned from mowing lawns.

Part 2:

Now, we need to figure out Jason's account balance at the end of the school year. From here, we take the new total of Jason's account balance and subtract it from how much he spent on lunches throughout the school year. So, it would look like this:

\(674.31-782.75=-108.44\)

Unfortunately, Jason has spent too much on his lunches and his account balance at the end of the school year is $-108.44

Answer: The answer is 1296

Answer:

Part A:

8 x 7 = 56; 56 x 10 = 560

Part B:

504

Part A & B explanation:

If you notice, there are no decimals in the answers so it's clear they round them. 8.4 rounded is 8 & 6.9 rounded is 7. To find the area of a singular rectangle is length x width. 8 x 7 = 56. In part A the directions say "best estimate" signaling that it isn't the exact answer you're looking for. 8 x 7 = 56; 56 x 9 = 504 would be the exact answer. (Answer for part b).Therefore, the answer for part A is 8 x 7 = 56; 56 x 10 = 560. Because 560 is the closest to 504 on the board.

Answer:

9 times

Step-by-step explanation:

The number 15 multiplied to the number 9 which gives the value 135.

To find the that how many 15 is to get 135, division should be performed.

So, dividing 135 by 15 gives:

= 135 ÷ 15

                         15 | 135 | 9

                                135

                            _______

                                   0

Thus, the quotient is 9.

Therefore, 15 goes into 135 exactly 9 times.

Answer:

-9 is the answer. is it right

Ok so first we do 12-3 which is 9 right but since it’s 3 and smaller than 12 we go backwards and put -9 so the answer is -9

Answer:

333 inches = 27.75 feet = 9.25 yards

To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).

Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)

where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.

First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:

\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)

Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:

\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)

Now, we can calculate the approximate volume using the Midpoint Rule:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)

Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

Answer:

\(\frac{16}{27}\)

Step-by-step explanation:

From the table, we notice that the total number of students is:

\(3+10+8+6=27\)

Then, along the second column of the table, we notice that the number of students who do not have a brother is:

\(10+6=16\)

So, the probability that a randomly chosen student does not have a brother is:

\(\frac{\text{number of students who do not have a brother}}{\text{total number of students}}=\frac{16}{27}\)
