A hotel had a number of meeting rooms, m, available for events. Each meeting room has 325 chairs.

Create an equation to represent c, the total number of chairs in all of the meeting rooms in the hotel.

Answer:

Step-by-step explanation:

basically, what they are asking you is to factor and then plug in the values (x=3; x=4) that they gave you.

first, you need to factor out the equation.

start with the original equation.

V=4x^3+10x^2+4x

factored form:

V= 2x(2x^2+5x+2)

next, you're going to want to plug in the values.

the answer asks for x=4, but you should do both.

v=2(3)(2(3)^2+5(3)+2)

do not forget to do the exponents before!

v=6(18+15+2)

v=6(35)

v=210 ft^2

that's the answer for if x was equal to 3.

V= 2x(2x^2+5x+2)

don't forget to write the original equation first.

V=2(4)(2(4)^2+5(4)+2)

V=8(36+20+2)

⬆is your answer! hope this helped!!

Step-by-step explanation:

question 1) equal angels

8+19)=(9x+9)

x=10°

8x+19=99°

question 2) equal angels

(3x-26)=2x

x=26°

3x-26= 52°

question 3) different angels

180-(x+10) = x+50

180-x-10=x+50

170-x=x+50

2x=120

x= 60°

x+10= 70°

x+50=120°

question 4) equal angels

3x-31=x+59

2x=90

x=45°

x+59=104°

question 5) equal angels

6x+3=7x-12

x=15°

6x+3=93°

Answer:

$8,900

Step-by-step explanation:

You don't say anything about compounding. If this problem involves only simple interest, then the interest will be i = p*r*t and the account balance will be i + p.

Here i = $8,000*0.075*1.5 (representing 18 months)

         i + $900

At the end of 18 months there will be $8,000 + $900, or $8,900, in the account.

Answer: Mean Absolute Deviation Calculator

Instructions

This calculator computes the mean absolute deviation from a data set:

You do not need to specify whether the data is for an entire population or from a sample. Just type or paste all observed values in the box above. Values must be numeric and may be separated by commas, spaces or new-line. Press the "Submit Data" button to perform the computation. To clear the calculator, press "Reset".

What is the mean absolute deviation

The mean deviation is a measure of dispersion, A measure of by how much the values in the data set are likely to differ from their mean. The absolute value is used to avoid deviations with opposite signs cancelling each other out.

Mean absolute deviation formula

This calculator uses the following formula for calculating the mean absolute deviation:

$ MAD =\frac{1}{n} \sum_{i=1}^n |x_i-\bar{x}|$

where n is the number of observed values, x-bar is the mean of the observed values and xi are the individual values.

Answer: How to find diagonal length of a rectangular prism?

Step-by-step explanation:To find the diagonal distance of a prism, you can use the formula: \displaystyle d = \sqrt{w^{2} + l^{2} + h^{2}}, where = height; = width, and = length. \displaystyle d = \sqrt{2^{2} + 8^{2} + 10^{2} } = \sqrt{4 + 64 + 100} = \sqrt{168} = \sqrt{4 * 42} = 2\sqrt{42}.

==============================================================

Explanation:

For now, let's ignore the 73 pounds.

The 13 ounces she gains is added onto the initial 3 ounces to get 3+13 = 16 ounces = 1 pound.

So we add this 1 pound onto the 73 pounds from earlier to get the answer to be 73+1 = 74 pounds

-----------------

We could write the steps out like this

(73 pounds, 3 ounces) + (13 ounces)

(73 pounds + 3 ounces) + (0 pounds + 13 ounces)

(73 pounds + 0 pounds) + (3 ounces + 13 ounces)

73 pounds + 16 ounces

73 pounds + 1 pound

74 pounds
