In how many ways can you select a committee of four students of a group of nine students?
Answer:
126
Step-by-step explanation:
n! / (r! (n-r)!)
In this case n = 9 and r = 4
9!/ (4! * (9-4)!)
9!/ (4! * 5!)
= 126
9! = 9x8x7x6x5x4x3x2x1

What would be the profit when the price is $35?
Step-by-step explanation:
The total expenses stay the same at $92,039.
The income changes to 12,000 × $35 = $420,000.
So the profit is $420,000 − $92,039 = $327,961.
Why might you need to use the addition or subtraction property of equality more than once after you have used the distributive property and combined like terms?
Answer:
If there is a variable term and a constant on each side of the equation, then you will need to use the addition or subtraction property of equality once to isolate the variable term and once to isolate the constant.

Joanne and Ed Greenwood built a new barn with an attached arena. To finance the loan, they paid $1,326 interest on $47,600 at 4%. What was the time, using exact interest? (Do not round intermediate calculations. Round up your answer to the nearest day.)
Step-by-step explanation
Note that
Interest is represented by I=1326
The principal is represented by P=47,600
Rate is R =4%
And Time is year
Interest is calculated using the formulae,
I =PRT/100
From the above formulae, time can be calculated as
T=100I/PR
T= 100×1326/(47600×4)
T= 132600/190400
T= 0.6964 years
To convert to days, multiply by 365(since those no of days make a year)
T= 0.6964×365=254 days
This was approximated to the nearest day
Answer is 254 days

During the first half of a football game, a running back ran for 9 total yards. In the second half, he ran for a loss of 12 yards. What was the running back's total yardage?
Answer:
21
Step-by-step explanation:
The running back's total yardage is 21 yards
From the question we are given the following parameters
Distance travelled in the first half of the game is 9 yards
Distance travelled in the second half of the game is 12 years
In order to determine the running back's total yardage, we will take the sum of the distance travelled as shown
Total distance travelled = 9 yards + 12 yards
Total distance travelled = 21 yards
Hence the running back's total yardage is 21 yards

19c + 31 = 26c - 74
solve for c
Answer:c
c = - 15
Step-by-step explanation:
Simplifying
19c + 31 = 26c + -74
Reorder the terms:
31 + 19c = 26c + -74
Reorder the terms:
31 + 19c = -74 + 26c
Solving
31 + 19c = -74 + 26c
Solving for variable 'c'.
Move all terms containing c to the left, all other terms to the right.
Add '-26c' to each side of the equation.
31 + 19c + -26c = -74 + 26c + -26c
Combine like terms: 19c + -26c = -7c
31 + -7c = -74 + 26c + -26c
Combine like terms: 26c + -26c = 0
31 + -7c = -74 + 0
31 + -7c = -74
Add '-31' to each side of the equation.
31 + -31 + -7c = -74 + -31
Combine like terms: 31 + -31 = 0
0 + -7c = -74 + -31
-7c = -74 + -31
Combine like terms: -74 + -31 = -105
-7c = -105
Divide each side by '-7'.
c = 15
Simplifying
c = - 15

The diagram shows a window in the shape of a square. Each side of the measures 8 √5 centimeters, and the area of the square is 32x square centimeters. What is the value of x?
Answer:
x = 10
Step-by-step explanation:
recall that for a square with side length "L", the area of the square can be expressed as
Area = L x L
or
Area = L²
in this case we are given that Area, A = 32x
and that Side Length, L = 8√5
If we substitute these into the equation, we will get:
Area = L²
32x = (8√5)² (using the properticals of exponents, we can re-write the right side)
32x = (8)² · (√5)²
32x = 64 · 5
32x = 320 (divide both sides by 32)
x = 320 / 32
x = 10

acomoda 2 8 3 y 4 en este orden con las operaciones +-×÷ de forma que el resultado sea 76 y 40
Answer:
[(2*8) + 3] *4 = 76
[2*(8 - 3)]*4 = 40
Step-by-step explanation:
Los paréntesis ( ), corchetes [ ] y llaves {} son símbolos de agrupación que indican el orden de las cuatro operaciones aritméticas básicas (suma, resta, multiplicación y división). Las reglas del orden de operaciones establece que se debe realizar primero el cálculo dentro de los símbolos de agrupación.
En otras palabras, la jerarquía de operaciones es el orden en el que hay que realizar las distintas operaciones, ya que unas tienen prioridad frente a otras. Y establece primero debes empezar por resolver los paréntesis, luego los corchetes y finalmente las llaves. Es decir, cuando haya símbolos de agrupación dentro de símbolos de agrupación, calcula de adentro hacia afuera. Esto es, empieza simplificando los símbolos de agrupación en el centro.
Para obtener 76, se pueden realizar la siguiente operación combinada:
[(2*8) + 3] *4
Aplicando lo anteriormente mencionado de la jerarquía de operaciones, comienzas por resolver el paréntesis:
[16 + 3]*4
Ahora, resolviendo el corchete:
19*4
Finalmente, resolviendo la multiplicación:
19*4= 76
Entonces [(2*8) + 3] *4 =76
Para obtener 40, se pueden realizar la siguiente operación combinada:
[2*(8 - 3)]*4
Comenzando a resolver el paréntesis:
[2*5]*4
Ahora, resolviendo el corchete:
10*4
Finalmente, resolviendo la multiplicación:
10*4= 40
Entonces [2*(8 - 3)]*4 = 40
