Answer:
Tickets Sold: 146
Step-by-step explanation:
Let's assume that the number of adult tickets sold is "x".
According to the problem, the number of student tickets sold is three times the number of adult tickets sold. Therefore, the number of student tickets sold is 3x.
The total number of tickets sold is 584, so we can set up an equation:
x + 3x = 584
Simplifying the equation, we get:
4x = 584
Dividing both sides by 4, we get:
x = 146
Therefore, the number of adult tickets sold is 146.
Answer: 146
Step-by-step explanation:
let x = # of adult tickets sold
let y = # of student tickets sold
x + y = 584
this is because the sum of adult tickets and student tickets is 584.
3x = y
this equation is written because there is 3 times more students there than adults
using substitution, we can find the equation :
x + (3x) = 584
4x = 584
x = 146
since x is equal to the number of adult tickets sold, your answer is 146.

The probability that the student was female and got grade C is P ( A ) = 0.12833
Given data ,
Let the table represent the group of students with their gender and the grades in school
Now , the probability that the student was female = total number of females / total number of students
So , probability that the student was female = 22/60
Now , the probability that the student got grade C = 21/60
So , the compound probability P ( A ) = probability that the student was female and got grade C
On simplifying , we get
P ( A ) = ( 22/60 ) ( 21/60 )
P ( A ) = 462/3600
P ( A ) = 0.12833
Hence , the probability is P ( A ) = 0.12833

An amount of $21,000 is borrowed for 13 years at 8.75% interest, compounded annually. If the loan is paid in full at the end of that period, how much must be paid back?
Answer: To solve this problem, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
A is the final amount
P is the initial principal (the amount borrowed)
r is the annual interest rate (as a decimal)
n is the number of times the interest is compounded per year
t is the time period in years
In this case, we have:
P = $21,000
r = 8.75% = 0.0875
n = 1 (interest is compounded annually)
t = 13 years
So, plugging these values into the formula, we get:
A = 21,000(1 + 0.0875/1)^(1*13)
A = 21,000(1.0875)^13
A = $58,150.51
Therefore, if the loan is paid in full at the end of the 13-year period, $58,150.51 must be paid back, which includes the original principal plus the interest accrued over the 13-year period.

The derivative of the function is f' ( x ) = 9 / ( 4 + 3x ) ( ln 2 )
Given data ,
Let the function be represented as f ( x )
Now , the value of f ( x ) is
f ( x ) = log₂ ( 3x + 4 )³
On simplifying , we get
On taking the derivative of the function , we get
f' ( x ) = d/dx ( log₂ ( 3x + 4 )³ )
d/dx ( log₂ ( 3x + 4 )³ ) = 1/ ln ( 2 ) [ d/dx( 3x + 4 )³ ]
On applying chain rule , we get
f' ( x ) = 1/ ln ( 2 ) 1/( 3x + 4 )³ ( 9 ( 3x + 4 )² )
So , cancelling out the similar terms , we get
f' ( x ) = 9 / ( 4 + 3x ) ( ln 2 )

La señora Luisa pide un presupuesto para reparar ocho joyas. El encargado de la joyería le dice que cobrará $6 por la primera joya, y por cada pieza sucesiva lo triple que la anterior. ¿Cuánto le cobrará el joyero a la señora Luisa?
The amount that the jeweler would charge Mrs. Luisa, given the prices of the successive jewelry would be $ 19, 680
How to find the total cost ?The charge for repairing the jewelry pieces is calculated in a geometric progression:
= 6, 63, 63 ², 63 ³, ..., 63 ⁷
The sum of the first n terms in such a progression is:
S = a x (r ⁿ - 1) / ( r - 1 )
Seeing as there are 8 pieces of jewelry, the total cost to Mrs. Luisa would be:
S = 6 x ( 3 ⁸ - 1) / ( 3 - 1 )
S = 6 x ( 6561 - 1 ) / 2
S = 6 x 6560 / 2
S = 3 x 6560

Dos ángulos de un cuadrilátero miden 60° y 80°. Los otros dos ángulos están en una
proporción de 2:9. ¿Cuáles son las medidas de esos dos ángulos?
Answer:
La suma de los cuatro ángulos de un cuadrilátero es igual a 360 grados. Entonces, si dos ángulos miden 60° y 80°, la suma de esos ángulos es de 140 grados.
Los otros dos ángulos están en una proporción de 2:9, lo que significa que la suma de sus medidas es de 11 partes. Si representamos las medidas de estos ángulos como 2x y 9x, respectivamente, entonces podemos escribir la ecuación:
2x + 9x = 11 partes
11x = 11 partes
x = 1 parte
Por lo tanto, el ángulo más pequeño mide 2x = 2 partes o 2 × 1 = 2 grados, y el ángulo más grande mide 9x = 9 partes o 9 × 1 = 9 grados.
En resumen, los dos ángulos faltantes miden 2° y 9°.

24.6%
Step-by-step explanation:
Use binomial probability:
P = nCr pʳ qⁿ⁻ʳ
where n is the number of trials,
r is the number of successes,
p is the probability of success,
and q is the probability of failure (1−p).
n = 9, r = 4, p = 0.5

if y varies inversely as the same of x, and =7/4 whenx = 1, find y when x=3
if y varies inversely as the same of x, and y=7/4 when x = 1 then value of y is 7/12 when x=3
If y varies inversely as the same of x, we can write the equation:
y = k / x
where k is the constant of proportionality.
Let us find the value of constant of proportionality k:
y = 7/4 when x = 1
7/4 = k / 1
Apply cross multiplication we get:
7/4 = k
k=7/4
Now plug in the value of k to find y when x = 3:
y = k /x
y = (7/4) / 3
When a fraction is divided by the whole number then fraction is multiplied with reciprocal of the whole number.
y=7/4×1/3

A small rectangular prism has a length of 5 inches, a width of 4 inches, and a volume of 100 cubic inches. A large rectangular prism also has a length of 5 inches and a width of 4 inches, but its volume is 200 cubic inches.
How much taller is the large prism than the small prism?
Write your answer as a whole number or decimal. Do not round.
the volume of a prism is
length × width × height
so, for the small prism we have
5 × 4 × height = 100 in
height = 100/20 = 5 i
for the large prism we have
5 × 4 × height = 200 in³
height = 200/20 = 10 in

Getx-1 in the numerator.
Get (x-7)(√x+2-3) in the denominator.
O Divide out a common factor of x-7.
Calculate the limit as 1.
The correct statement is:
"Divide out a common factor of x - 7." The limit of the given expression is 1/6.
Multiply by (√(x + 2) + 3)/(√(x + 2) + 3):
This statement is not correct.
We generally multiply by the conjugate of the expression to eliminate square roots, but in this case, multiplying by (√(x + 2) + 3)/(√(x + 2) + 3) does not help simplify the expression.
Get x - 1 in the numerator:
This statement is not correct. The expression does not involve x - 1 in the numerator.
Get (x - 7)(√(x + 2) - 3) in the denominator:
This statement is not correct. We want to simplify the expression, not introduce a more complex denominator.
Divide out a common factor of x - 7:
This statement is correct. By factoring out (x - 7) from both the numerator and denominator, we can cancel out the common factor.
Calculate the limit as 1/6:
This statement is not correct. We need to perform further simplification to determine the limit.
After canceling out the common factor of x - 7, the simplified expression becomes:
lim x -> 7 (√(x + 2) - 3)/(x - 7) = lim x -> 7 1/(√(x + 2) + 3)
To find the limit, we substitute the value x = 7 into the simplified expression:
lim x -> 7 1/(√(7 + 2) + 3) = 1/(√(9) + 3) = 1/(3 + 3) = 1/6
Therefore, the correct statement is: "Divide out a common factor of x - 7." The limit of the given expression is 1/6.

An earthquake in Gansu, China, on December 16, 1920, measured 8.6 on the Richter scale and killed 100 000 people. An earthquake that usually causes no damage measures 4 on the Richter scale. Compare the intensities of the two earthquakes. (THE ANSWER IS 40000).
The intensity of the Gansu earthquake was approximately 39,811 times greater than that of an earthquake measuring 4 on the Richter scale, which typically causes no damage.
Let's compare the intensities of the two earthquakes using the Richter scale.
Step 1: Understand that the Richter scale is logarithmic, which means each whole number increase represents a tenfold increase in intensity.
Step 2: Determine the difference between the magnitudes of the two earthquakes. The Gansu earthquake measured 8.6, and the earthquake causing no damage measured 4.
8.6 - 4 = 4.6
Step 3: Calculate the intensity ratio between the two earthquakes using the difference in magnitudes. Since each whole number increase represents a tenfold increase in intensity, we need to raise 10 to the power of the difference.
10^4.6 ≈ 39,810.71705535
Step 4: Round the result to a whole number.
39,810.71705535 ≈ 39,811
The intensity of the Gansu earthquake was approximately 39,811 times greater than that of an earthquake measuring 4 on the Richter scale, which typically causes no damage.

y = mx + c ( m is the slope and c the y- intercept )
given
5x - 9y = 45 ( subtract 5x from both sides )
