Answer 1

Answer:

FC = 27

QC = 18

Step-by-step explanation:

The centroid divides the median in which it stands into a ratio of 1:2

The longer length being twice of the shorter

So in this case, what we have is that ;

FC = FQ + QC

with QC twice FQ

so QC = 2(9) = 18

while;

FC = 18 + 9 = 27

Mrs. Barker bought some books at a book sale, including 4 paperback books. 20% of all the books she bought were paperback. How many books did Mrs. Barker buy in all?

Answers

Answer:

20

Step-by-step explanation:

Number of paperback books = 4

Percentage of total books that were paperbacks = 20%

Let total number of books = x

Hence,

20% of total books = paperback books

20% of x = 4

0.2 * x = 4

0.2x = 4

0.2x / 0.2 = 4 / 0.2

x = 20

Total number of books = 20

What is the solution to the linear equation? d – 10 – 2d + 7 = 8 + d – 10 – 3d

Answers

Answer:

d = 0.33

Step-by-step explanation:

First off, you want to get like terms next to each other. We'll move the numbers with variables on one side and normal numbers on the other. Since we're changing the sides of the equal sign they're on, this also changes whether their positive or negative.

d - d - 2d + 3d = 10 -7 + 8 - 10

Now that they're together, we can add or subtract them. The variables without numbers can be ones for this equation.

3d = 1

Now we divide 1 by 3 to find what d equals.

3d/3 = 1/3

d = 0.33

Answer:

216 Minutes

Step-by-step explanation:

2x=18

x=9

Every mile is 9 minutes, so we can multiply 9 by 26:

234 minutes

But he has already ran for 18 minutes, so we can subtract:

234-18=216

Answer:

216mins  

Step-by-step explanation:

first divide 2/18 by 2 to see the rate and you get 1/9 so he runs 1 mile every 9 mins. You multiply 9 by 26 to get your answer and you get 234 subtract 18 and it will take him 216 more mins

Answer:

3/5 (Already there but I wanted to put an explanation)

Step-by-step explanation:

first you want to change the 1/2 to work better with the 1/10. The way you can do is change the 1/2 to be 5/10 by multiplying both sides of the fraction by 5 so that it is out of 10 rather than out of 2. you then add 5/10 to 1/10 to get x=6/10. since 6/10 can be simplified by 2, you divide both sides of the fraction by 2 to get 3/5=x

if a function has a verticale asymptote at a certain x-value, then the function is at the value

Answers

Answer:

We conclude that If a function has a vertical asymptote at a certain x-value, then the function is undefined at the value.

Step-by-step explanation:

If a function has a vertical asymptote at a certain x-value, then the function is undefined at the value.

For example, let the function

[tex]f\left(x\right)\:=\frac{x+3}{x-3}[/tex]

It is clear that the given function becomes undefined at x = 3 in the denominator.

i.e. 3-3 = 0

It means, the function can not have x = 3, otherwise, the function will become undefined.

In other words, if the function has a vertical asymptote at x = 3, then the function is undefined at the value.

Therefore, we conclude that If a function has a vertical asymptote at a certain x-value, then the function is undefined at the value.

If QR is 17 more than twice x, RS is 19 less than six times x, and QS is one less than four times x, find x and the measure of each side

Answers

Complete question :

triangle QRS is an equilateral triangle. If QR is seventeen more than twice x, RS is 19 less than six times x, and QS is one less than four times x, find x and the measure of each side.

Answer:

x = 9

All sides have 35 units length

Step-by-step explanation:

Recall: Equilateral triangles have 3 sides, all of equal length.

QR = 2x + 17

RS = 6x - 19

QS = 4x - 1

Take :

QR = RS = QS

To find x

QR = RS

2x + 17 = 6x - 19

2x - 6x = - 19 - 17

-4x = - 36

x = 9

QR = 2(9) + 17 = 35

RS = 6(9) - 19 = 35

QS = 4(9) - 1 = 35

Answer:

Step-by-step explanation:

There are several ways you can go about this. The most straight-forward (and time-consuming) is to use a calculator to calculate the value for each cell of the table.

If you realize that the first row will be the base of the exponential, then you can finish filling that easily. The first row is completed by ...

  4^1 = 4, 5^1 = 5.

Each row below that is the immediately preceding row multiplied by the number in the first row. For example, to finish the second column, we have ...

  2^4 = 2·8 = 16

  2^5 = 2·16 = 32

__

When calculations are easily defined and repetitive, I like to use a spreadsheet to do them. It avoids errors, and (to me) is less tedious than repeating the same calculation over and over. The first row of this spreadsheet is sequential numbers, as described above. The remaining cells raise the first row value to the left column power.

Check all that apply.
HELP ME NOW PLEASE DONT GIVE A FAKE ANSWER PLEASEEEEEEEEEE

Answers

Answer:

y = 22; x = 8

y > x

Step-by-step explanation:

A larger number is double the sum of 3 and a smaller number. The larger number is 2 less than 3 times the smaller number. If y represents the larger number and x represents the smaller number, which equations model the situation? Check all that apply.

Let

Smaller Number = x

Larger number = y

larger number is double the sum of 3 and a Smaller number

Sum of 3 and a smaller number = 3 + x

y = 2(3 + x)

y = 6 + 2x (1)

Also

y = 3x - 2 (2)

Equate the equation of the larger number

6 + 2x = 3x - 2

6 + 2 = 3x - 2x

8 = x

x = 8

Substitute x = 8 into (1) to find y

y = 6 + 2x (1)

y = 6 + 2(8)

= 6 + 16

= 22

y = 22

y = 22; x = 8

Therefore,

y > x
