Using the formula with n = 25 , then

[tex]\frac{25(26)(50+1)}{6}[/tex]

= [tex]\frac{25(26)(51)}{6}[/tex]

= [tex]\frac{33150}{6}[/tex]

= 5525

Answer:

-9

Step-by-step explanation:

Use synthetic division here.  The divisor will be -2, which comes from the divisor (x + 2):

-2    /      1    0    0    -1

                   -2    4    -8

       -------------------------

              1      -2   4    -9

The remainder is -9.

Answer:

Negative 9 or -9 is the answer.

The area of a rectangle if the length is 5 more than 4 times the width, the algebraic expression for this is, A = (4b + 5) × b

An area is total space occupied by two-dimensional or flat surfaces. In other words we can say that it is a number of unit squares present in a closed figure. We use various units for measurement of area like, cm², m², ft², mm².

Given that,

The length is 5 units more than 4 times the width

Suppose,

length = l

width = b

So, according to given condition

l = 4b + 5

Now, the area for rectangle is

A = length × width

A = l × b

A = (4b + 5) × b

Hence, the algebraic expression is (4b + 5) × b

Answer:

B

Step-by-step explanation:

Use the distance formula in 3 dimensions

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2+(z_{2}-z_{1})^2 }[/tex]

with (x₁, y₁, z₁ ) = (3, 4, 10) and (x₂, y₂, z₂ ) = (8, 4, - 2)

d = [tex]\sqrt{(8-3)^2+(4-4)^2+(-2-10)^2}[/tex]

   = [tex]\sqrt{5^2+0^2+(-12)^2}[/tex]

    = [tex]\sqrt{25+144}[/tex]

    = [tex]\sqrt{169}[/tex]

here's your solution

==> Total number of students in class = 45

==> percentage of girls in class = 60%

==> number of girls in class = (60/100)*45

==> number of girls = 27

==> number of boys = 45 - 27

==> number of boys = 18

Answer:

45.5

Step-by-step explanation:

First, you need to put the data in order: 37, 39, 41, 43, 48, 51, 52, 54

I'm not sure what 5 median means, but to find the median, you look for the middle number of the data set.

43 + 48 = 91      

then, you divide the numbers by 2 to get the median.

91/2= 45.5

So, the median is 45.5

First convert 4.5 hours to minutes

4.5 hours = 270 minutes

6:30 = ?:270

Divide 270 and 30

270/30 = 9

Then multiply 6 and 9

9*6 = 54

The event planner can set up 54 tables in 4.5 hours(270 minutes)

Step-by-step explanation:

Answer:

Wait ima ask my mom to help you with this.

Step-by-step explanation:

Answer:

So first we have to figure out what $1200 per month for 12 months is since it was a year. 1200x12=14,400 a year which is outrageous for an apartment just saying.

Then we find out what 12% of the 1200 is and then add it to 1200.

To find the percentage of that we need to know how many times 12 fits into 100% 12 fits into 100 a total of 8.33333333333 times.

So now we divide 1200 by 8.33333333333 to see what 12% of it is.

1200 divided by 8.33333333333 is 144. So 1200+144=1344.

Now since one of the nine years has passed already we only have 8 remaining.

Now we see what 1344 a month for 12 months is 16,128 a year.

Now we multiply 16,128 by 8 to get the outcome of 8 more years. So 16,128x8=129,024

Step-by-step explanation:

Answer:

The grapes are more expensive than the green grapes.

Step-by-step explanation:

GRAPES: If you divide $20.72 by 7, to get one bag of grapes instead of seven, you get $2.96/bag.

GREEN GRAPES: If you divide $8.46 by 3, to get one bag of green grapes instead of three, you get $2.82/bag.

$2.82 is less than $2.96, therefore, the grapes are more expensive than the green grapes.

~Answer~

Substitute your numbers:

y = 5x

For the first one, y equals 5, so substitute 5 for y.

So, 5 = 5x.

What multiplied by 5 gives 5? The answer is 1.

So, the first one is 1.

Do the same for all the others.

So, 4 = 5x.

4 = 5(4/5)

As a decimal that equals 0.8.

For the last one, I can't tell if that is saying 2 or .2 so I'll do both.

for 2, you will do 2 = 5x and for .2, you will do .2 or 0.2 = 5x.

For 2, it would be 2/5 or 0.4.

For .2 or 0.2, it would be 0.04.

So,

x                                                             y

1                                                             5

4/5 or 0.8                                             4

0.4 if it is 2 and 0.04 if it is 0.2.        2

(looking back, I'm pretty sure it was just 2 and not .2)

I hope this is what u were looking for, if not I'm so sorry for a useless answer.  I wasn't completely sure whether I was doing it right since I haven't done these types of math problems in some time.
