If 4 faculty members are chosen from total of 8 faculty members, this can be done in 8C4 number of ways.
8C4 = 8!/(8-4)!4!
8C4 = 8!/4!4!
8C4 = 8*7*6*5*4!/4!*4*3*2
8c4 = 8*7*6*5/24
8C4 = 7*5*2
8C4 =70 ways
Similarly, 5 students are to be selected from a pool of 13 students, this can be done in 13C5 number of ways.
13C5 = 13!/(13-5)!5!
13C5 = 13!/8!5!
13C5 = 13*12*11*10*9*8!/8!*5*4*3*2
13C5 = 13*12*11*10*9/120
13C5 = 1,287 ways
The total number of ways the committee can be formed is 8C4 * 13C5 = 70*1287
The total number of ways the committee can be formed is 90,090 ways

A car leaves at 9 : 00 a.m. and drives at a constant speed. It is 20 miles from its starting point at 9 : 30 a.m. At what time will the car be 200 miles from its starting point?
PLSSSS HELP
Answer:
2:00 PM
Step-by-step explanation:
I figured out that the car is going 40 mph seeing as how it went 20 miles in 30 minutes.
I used this and found out how many hours it would take to get to 200 miles at this rate:
200/40 = 5
I divided 40 by 200 as 200 is the end goal and the car is going 40 mph.
The 5 is 5 hours, so I added 9 and 5 to get 14 which is 2:00 PM
Hope this helps!! :)

x2−10x+29=5
Step 1 of 2: Using the standard form ax2+bx+c=0 of the given quadratic equation, factor the left hand side of the equation into two linear factors.
Answer:
(x-6)(x-4) = 0
Step-by-step explanation:
Subtract 5 from both sides to make the equation equal to 0. You will get the equation x2-10x+24=0. Now think of two numbers that multiply to get 24 but add to get -10. These numbers are -6 and -4. The factors of x2 are x and x which multiply to get x2. Now put two linear factors into parathesis to get (x-6)(x-4) = 0.
The local newspaper has letters to the editor for 40 people if this is the number represents 5% of all the newspaper readers how many readers does the newspaper have. fill in the blanks
40/5= 8 8 is 1% of the total people, 1% x 100 = 100%
8 x 100 = 800 people
The answer to this question would be: The newspaper has Eight hundred readers.
Part = Percent x Whole
40 = 5% x 800
Do the equation above to make sure your correct( it is) and if it doesn't come back to 40 then your math is incorrect and you have the incorrect answer
Do that with all math that your trying to find the whole for, its a helpful thing.

For a given show, a theater charges $80 for a premium ticket and $30 for a regular ticket. If a total of n tickets were sold and p of them were premium tickets, what is the total amount, in dollars, from the sale of regular tickets and premium tickets?
Please explain the process.
Answer:
50p + 30n
Step-by-step explanation:
Cost of each premium ticket = $80.
Cost of each regular ticket = $30
Total tickets sold = n
We are told that p tickets were sold. Thus;
Total tickets sold is; p + (n - p)
Thus total amount generated is;
T = 80p + 30(n - p)
T = 50p + 30n

Answer:
NM = [tex]\sf \sqrt{70}[/tex]
Step-by-step explanation:
Let NM = y
If KL is twice the length of NM, then KL = 2y
Given:
KM = 20NO = 7As ΔKLN ~ ΔNOM
KL : KM = NO : NM
[tex]\sf \implies 2y : 20 = 7 : y[/tex]
[tex]\sf \implies \dfrac{2y}{20}=\dfrac{7}{y}[/tex]
[tex]\sf \implies 2y \cdot y=7 \cdot 20[/tex]
[tex]\sf \implies 2y^2=140[/tex]
[tex]\sf \implies y^2=70[/tex]
[tex]\sf \implies y=\sqrt{70}[/tex]
As NM = y, then NM = [tex]\sf \sqrt{70}[/tex]
Answer:
NM = [tex]\sqrt{70}[/tex]
Step-by-step explanation:
Δ NMO and Δ KML are similar ( by the AA postulate )
Then the ratios of corresponding sides are in proportion, that is
[tex]\frac{NM}{KM}[/tex] = [tex]\frac{NO}{KL}[/tex] ( substitute values, noting KL = 2NM )
[tex]\frac{KM}{29}[/tex] = [tex]\frac{7}{2NM}[/tex] ( cross- multiply )
2 NM² = 140 ( divide both sides by 2 )
NM² = 70 ( take the square root of both sides )
NM = [tex]\sqrt{70}[/tex]
Solve for m.
m/10 - 1/2 = 1/5
m is equal to 7
Step-by-step explanation:
trust me bro
Answer:
m=7
Step-by-step explanation:
[tex]\frac{m}{10}-\frac{1}{2}=\frac{1}{5}[/tex]
[tex]\mathrm{Add\:}\frac{1}{2}\mathrm{\:to\:both\:sides}[/tex]
[tex]\frac{m}{10}-\frac{1}{2}+\frac{1}{2}=\frac{1}{5}+\frac{1}{2}[/tex]
[tex]\mathrm{Simplify}[/tex]
[tex]\frac{m}{10}=\frac{7}{10}[/tex]
[tex]\mathrm{Multiply\:both\:sides\:by\:}10[/tex]
[tex]\frac{10m}{10}=\frac{7\cdot \:10}{10}[/tex]
[tex]\mathrm{Simplify}[/tex]
[tex]m=7[/tex]

Janet has 3 cube-shaped boxes. Each box has a side length of 10 inches. What is the minimum amount of wrapping paper needed, in square feet, to wrap all 3 boxes
Answer:anyone here watch anime
Step-by-step explanation:
EREN JEAGER
The minimum amount of wrapping paper needed, in square feet, to wrap all 3 boxes is 12.5 square feet.
Side of each cube = 10 inches
Number of cubes =3
As we know The minimum amount of wrapping paper needed, in square feet, to wrap all 3 boxes will be the total surface area of all 3 boxes.
What is the total surface area of a cube?The total surface area of a cube with side a is 6a².
So, the total surface area of a cube with a side of 10 inches will be 6*10² = 6*100 = 600 square feet.
So, the total surface area of 3 cubes with a side of 10 inches will be 600*3 = 1800 square inches.
As we know that 1 square inch = 0.00694444 square feet
So, 1800 square inches = 1800*0.00694444 = 12.5 square feet.
Therefore, the minimum amount of wrapping paper needed, in square feet, to wrap all 3 boxes is 12.5 square feet.
