One number is 16 more than the other and their average is 60. The numbers are *
Answers
Answer:
68
Step-by-step explanation:
Let The first number = X
& the Second one = X + 16
Sum of these two numbers = 120
X + X + 16 = 120
2X = 120 - 16
2X = 104
X = 52
So , the first number = 52
& Second one = 52 + 16 = 68
Answer:
The numbers are 52 and 68.
Step-by-step explanation:
Let x be the first number and y be the second. The question tells us that:
1) x = y + 16
2) (x + y) / 2 = 60
2 equations, 2 unknowns. Solve the system. Plug equation 1 into equation 2:
(y + 16 + y) / 2 = 60
2y + 16 = 120
y + 8 = 60
y = 52
Now plug the value of y back into either original equation. I'll use the first:
x = 52 + 16
x = 68
The school that Mark attends is selling tickets to a spring musical. On the first day
of ticket sales, the school sold 3 adult tickets and 8 student tickets for a total of $60.
The school took in $88 on the second day by selling 10 adult tickets and 8 student
tickets. What is the price of each adult ticket and child ticket?
Adult: $
Student: $
Answers
Answer:
Adult=4, Student=6
Step-by-step explanation:
a=adult, s=student
3a+8s=60 equation 1
10a+8s=88 equation 2
-3a-8s=-60 multiply equation 1 by -1
7a = 28 add above 2 equations
a=4
solve for s by inserting a value into either equation
3a+8s=60
3(4)+8s=60
12+8s=60
8s=48
s=6

Answers
Answer:
B. [tex]^{5} P_{5}[/tex] × [tex]^{20} P_{15}[/tex]
Step-by-step explanation:
No. of students from first grade = 15
No. of students from second grade = 5
There are 5 rows of seats
Each row contains 5 seats
Total seats = 25
No. of ways for second-grade students to occupy the first row (i.e first 5 seats) = [tex]^{5} P_{5}[/tex]
Remaining seats = 20
So, now we are left with 15 first grade students
So, No. of ways for first-grade students occupy remaining seats = [tex]^{20} P_{15}[/tex]
Using the counting rule principle,
No. of ways for the students can be seated if all of the second-grade students occupy the first row = [tex]^{5} P_{5}[/tex] × [tex]^{20} P_{15}[/tex]
So, Option B is the correct answer
Hence, no. of ways for the students can be seated if all of the second-grade students occupy the first row is ×
There are ¹⁵P₁₅ x ¹⁰P₅ possible way to seat, if all of the second-grade students occupy the first row.
What is permutation?A permutation in math is the number of ways in which a set of data or objects can be ordered or arranged, where the order matters.
Given that, a school bus has 25 seats, with 5 rows of 5 seats. 15 students from the first grade and 5 students from the second-grade travel in the bus.
Since you have to place all first-grade students in the first three rows,
Therefore,
For the 15 first-graders of the first three rows (15 seats), we have ¹⁵P₁₅ since all 15 places have to be occupied by all 15 first-graders.
Then we have 10 remaining seats left to be assigned to the 5 second-graders = ¹⁰P₅
We then multiply the permutation numbers of those two arrangements to get the total ways:
¹⁵P₁₅ x ¹⁰P₅
Hence there are ¹⁵P₁₅ x ¹⁰P₅ possible way to seat, if all of the second-grade students occupy the first row.

Probability[Selected ball is a white ball without replacement (W)] = 5 / 22
Step-by-step explanation:
Given:
Number of white ball in jar = 5
Number of black ball in jar = 6
Find;
Probability[Selected ball is a white ball without replacement (W)]
Computation:
Probability of an event = Number of favorable outcomes / Total number of outcomes
Probability of 1st white ball = 5 / [5 + 6]
Probability of 1st white ball = 5 / 11
Probability of 2nd white ball [without replacement] = 5 / [11 - 1]
Probability of 2nd white ball [without replacement] = 5 / 10
Probability[Selected ball is a white ball without replacement (W)] = [5/11][5/10]
Probability[Selected ball is a white ball without replacement (W)] = 25 / 110
Probability[Selected ball is a white ball without replacement (W)] = 5 / 22

Hola, alguien me puede resolver esta operación? a. Múltiplo de 5 y de 6 mayor que 95.000 ( _ 8 9 1 _ ) b. Divisible por 3, 4 y 5, menor que 4.675. ( 4 6 _ _ )
Answers
Answer:
a) 98,910
b) 4,620
Step-by-step explanation:
Recordar que un numero N es multiplo de A si N es divisible por A.
Entonces, decir:
Buscar N, tal que sea multiplo de A
es lo mismo que decir:
Buscar N, tal que sea divisible por A.
a) Queremos un múltiplo de 5 y de 6 mayor que 95.000
( _ 8 9 1 _ )
Sabemos que los múltiplos de 5 terminan en 0 o 5.
Y un número de 5 dígitos mayor que 95,000 requiere que el quinto digito en este caso sea 9, entonces tendremos:
98,91_
Para encontrar el dígito de las unidades, podemos probar remplazarlo por 0 y por 5, y luego dividirlo por 6.
Si el resultado es un número entero, entonces el número será un múltiplo de 6.
Probemos con 0, vamos a tener el número:
98,910
dividiéndolo por 6 obtenemos:
98,910/6 = 16,485
Entonces:
98,910 es más grande que 95,000
es múltiplo de 5 (porque termina en cero)
Y es múltiplo de 6, como acabamos de comprobar.
b) Ahora queremos un número divisible por 3, 4 y 5, que sea menor que 4,675
4,6__
De vuelta, como tiene que ser divisible por 5, sabemos que termina en 5 o 0.
Y como también tiene que ser divisible por 4, sabemos que tiene que terminar si o si en número par, entonces podemos concluir que solo puede terminar en 0.
Así, sabemos que el número va a ser algo como:
4,6_0
Ahora podemos probar con el dígito de las decenas, de tal forma que el número sea divisible por 3, 4 y 5.
Recordar que este número tiene que ser menor que 4,675
Entonces el número faltante puede ser:
0, 1, 2, 3, 4, 5, 6, 7
Ahora también podemos recordar que un número es solo divisible por 3 si la suma de todos sus dígitos es divisible por 3.
Entonces tenemos que tener que:
4 + 6 + x + 0 = múltiplo de 3
10 + x = múltiplo de 3
Los posibles valores de x van a ser:
x = 2 (porque 12 es múltiplo de 3)
x = 5 (porque 15 es múltiplo de 3)
Ok, ahora sabemos que el número restante solo puede ser 2 o 3.
Entonces tenemos que remplazar esos valores en el número y ver si este es divisible por 4 o no.
Comenzamos con el 2.
Tendremos el número:
4,620
Probamos dividiendo esto por 4:
4,620/4 = 1,155
El resultado es entero, entonces 4,620 es divisible por 4 (y por como lo creamos, también sabemos que es divisible por 3 y por 5, y además es menor que 4,675, como queríamos)

Fiona leaves $1600 in the bank for four years. It earns compound interest of 4% each year. Calculate the total amount Fiona has in the bank at the end of the four years
Answers
Answer:
A = $1,871.77
Step-by-step explanation:
A = P(1 + r/n)nt
Where,
A = Total money in the bank
P = principal = $1,600
r = interest rate = 4% = 0.04
n = number of periods = 1 year
t = time = 4 years
A = P(1 + r/n)^nt
A = 1,600(1 + 0.04/1)^1*4
A = 1,600(1 + 0.04)^4
= 1600(1.04)^4
= 1600(1.16985856)
= 1,871.773696
Approximately,
A = $1,871.77
John had to pay a combined electric and gas bill $150. The electric portion of the bill was $90. What is the ratio of money spent on electric to that on gas?
Answers
Given:
John had to pay a combined electric and gas bill $150.
The electric portion of the bill was $90.
To find:
The ratio of money spent on electric to that on gas.
Solution:
Let x be the amount of gas bill.
The electric portion of the bill was $90 and John had to pay a combined electric and gas bill $150. So,
[tex]90+x=150[/tex]
[tex]x=150-90[/tex]
[tex]x=60[/tex]
The gas portion of the bill was $60.
The ratio of money spent on electric to that on gas is:
[tex]\text{Required Ratio}=\dfrac{\text{Electric bill}}{\text{Gas bill}}[/tex]
[tex]\text{Required Ratio}=\dfrac{90}{60}[/tex]
[tex]\text{Required Ratio}=\dfrac{3}{2}[/tex]
[tex]\text{Required Ratio}=3:2[/tex]
Therefore, the ratio of money spent on electric to that on gas is 3:2.

Andreas plays soccer video game he earns three stars for every goal he scores and loses 3/4 stars every time he misses the goal he scores five goals and Misses the goal four times how many stars does he have
Answers
Answer: 12 stars
Step-by-step explanation:
First find out the number of stars he gained by scoring goals:
= Number of goals scored * Stars if goal is scored
= 5 * 3
= 15 stars
Then find out the number of stars he is to lose by missing the goal:
= No. of goals missed * stars if goal missed
= 4 * 3/4 stars
= 3 stars
The total number of stars he has are:
= Stars gained - Stars lost
= 15 - 3
= 12 stars

Line segment AB has endpoints A(6, 4) and B(2, 6). Find the coordinates of the point that divides the line segment directed from A to B in the ratio of 1:3.
Answers
Answer:
(3, 5.5)
Step-by-step explanation:
Given the line segment AB with endpoints A(6, 4) and B(2, 6). If the coordinates of the point divide the line segment directed from A to B in the ratio of 1:3, then;
M(X, Y) = {(ax1+bx2)/a+b, ay1+by2/a+b}
X = ax1+bx2/a+b
X = 1(6) + 3(2)/1+3
X = 6+6/4
X = 12/4
X = 3
Similarly;
Y = ay1+by2/a+b
Y = 1(4)+3(6)/1+3
Y = 4+18/4
Y = 22/4
Y = 5.5
Hence the required coordinate is (3, 5.5)
