Joe gave 1/4 of his total candies to his classmate then he gave 4/6 of when he had left to his brother when he went home then he realized that you didn’t give any to his sister he gave 25% of the remaining candies to her after all this he realized that he only had 21 candies left how many candies did he have In the beginning
Answer:
112
Step-by-step explanation:
Given: Joe gave 1/4 of his total candies to his classmate.
Then, he gave 4/6 of when he had left to his brother.
He gave 25% of the remaining candies to his sister.
Finally, he only had 21 candies left.
Lets assume the total number of candies at the beginning be "x".
First, finding the number candies left after giving candies to classmate.
∴ Remaining candies= [tex]x- x\times \frac{1}{4}[/tex]
Solving it to find remaining candies after giving candies to clasmate.
⇒ Remaining candies= [tex]x-\frac{x}{4}[/tex]
Taking LCD as 4
⇒ Remaining candies= [tex]\frac{4x-x}{4} = \frac{3x}{4}[/tex]
∴ Remaining candies after giving candies to clasmate= [tex]\frac{3x}{4}[/tex]
now, finding the candies left after giving candies to his brother.
∴ Remaining candies= [tex]\frac{3x}{4} - \frac{3x}{4} \times \frac{4}{6}[/tex]
Solving it to find the remaining candies after giving candies to his brother.
⇒ Remaining candies= [tex]\frac{3x}{4} - \frac{x}{2}[/tex]
Taking LCD 4
⇒ Remaining candies= [tex]\frac{3x-2x}{4} = \frac{x}{4}[/tex]
∴ Remaining candies after giving candies to his brother= [tex]\frac{x}{4}[/tex]
We know, Joe was left with only 21 candies after giving candies to his sister.
Therefore, putting an equation for remaining candies to find the number of candies at the beginning.
⇒[tex]\frac{x}{4} - 25\% \times \frac{x}{4} = 21[/tex]
⇒[tex]\frac{x}{4} - \frac{0.25x}{4} = 21[/tex]
Taking LCD 4
⇒ [tex]\frac{x-0.25x}{4} = 21[/tex]
⇒ [tex]\frac{0.75x}{4} = 21[/tex]
Multiplying both side by 4
⇒[tex]0.75x= 21\times 4[/tex]
dividing both side by 0.75
⇒[tex]x= \frac{21\times 4}{0.75}[/tex]
∴[tex]x= 112[/tex]
Hence, Joe had 112 candies at the beginning.

Step-by-step explanation:
21. Higher Order Thinking Amil and Abe
rode in a bike-a-thon. Abe rode for 77 minutes
at a faster rate per mile than Amil. Find Amil's
unit rate. Then explain how you could use it to
find a possible unit rate for Abe.
Amil rode 15 miles
in 55 minutes.
Amil's unit rate is calculated by dividing the distance traveled (15 miles) by the time in hours (0.917 hours), resulting in approximately 16.36 mph. Abe's unit rate is faster but cannot be precisely determined without more information about his distance or time.
Explanation:Amil rode 15 miles in 55 minutes. To find Amil's unit rate, we divide the total distance by the total time. The unit rate is a measure of speed, indicating how many miles are traveled in one minute. To find this unit rate, we perform the following calculation:
Convert the time from minutes to hours to find the unit rate in miles per hour (mph), since speed is often expressed this way: 55 minutes × (1 hour/60 minutes) = 0.917 hours
Divide the distance by the time: 15 miles ÷ 0.917 hours = 16.36 mph (rounded to two decimal places).
Amil's unit rate is approximately 16.36 mph. This information can be used to estimate Abe's unit rate, knowing that Abe rode at a faster rate. If we knew how far Abe rode or his unit rate in miles per minute, we could compare the two directly. Without additional information about Abe's distance or time, we can only say that Abe's unit rate exceeds 16.36 mph.
A mother is currently 7 times older than her son. In 2 years time, she will be 5 times older than her son.
Let x and y be the present ages of the son and mother respectively.
Use the fact that the mother is currently 7 times older than her son to set up an equation relating r and V (call this Equation 1).
Answer:

Find the sum of the first 90 terms of the sequence -4,-1,2,5,8
Answer:
1655
Step-by-step explanation:
Note the common difference d between consecutive terms of the sequence
d = - 1 - (- 4) = 2 - (- 1) = 5 - 2 = 8 - 5 = 3
This indicates the sequence is arithmetic with sum to n terms
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]
Here a₁ = - 4, d = 3 and n = 90, thus
[tex]S_{90}[/tex] = [tex]\frac{90}{2}[/tex] [ (2 × - 4) + (89 × 3) ] = 45(- 8 + 267) = 45 × 259 = 1655

A roller coaster starts with the cars being pulled up a ramp. The mass of the cars is estimated by the function m(p) = 175p + 1,180 where p is the number of passengers in the car. The potential energy of the car is calculated using the function E(m) = 9.8mh, where h is the height of the ramp.
If the top of the ramp is 30 meters, which function can be used to calculate the potential energy of a car in terms of the number of passengers?
Answer:
[tex]E(p)=51,450p+346,920[/tex]
Step-by-step explanation:
The function
[tex]m(p) = 175p + 1,180[/tex]
gives the mass of the car as a function of the number of passengers in it.
And the function
[tex]E(m) = 9.8m*h[/tex]
gives the potential energy of the car as a function of the car's mass.
Now if the height of the ramp is 30 meters, we have
[tex]E(m) =9.8m*(30)[/tex]
[tex]E(m) =294m[/tex]
And to find the potential energy as a function of the number of passengers, we just substitute [tex]m(p)[/tex] into [tex]E(m)[/tex] to get:
[tex]E(m(p))=294(175p+1180)[/tex]
[tex]\boxed{ E(p)=51,450p+346,920}[/tex]
which gives the potential energy as a function of the number of passengers.

Whats the answer to. 4r + 8 + 5 = -15 - 3r
To solve the equation 4r + 8 + 5 = -15 - 3r, combine like terms and isolate the variable r leading to the solution r = -4.
Explanation:The student is asking how to solve the algebraic equation 4r + 8 + 5 = -15 - 3r. To solve for r, we must first simplify and combine like terms. This means we need to get all the terms with r on one side of the equation and the constant numbers on the other side.
Therefore, the solution to the equation is r = -4.
Final answer:
The solution to the equation 4r + 8 + 5 = -15 - 3r is r = -4.
Explanation:
The algebraic equation provided by the student is 4r + 8 + 5 = -15 - 3r.
To solve for r, we must first simplify and rearrange the equation by combining like terms and moving the variables to one side and the constants to the other.
By subtracting 3r from both sides and also subtracting 8 + 5 from both sides, we end up with 4r + 3r = -15 - 8 - 5. Simplifying further, we get 7r = -28.
Finally, dividing both sides by 7 yields r = -4.

what is the vertex of the quadratic function below y=3x^2-12x+17
Answer:
(2, 5 )
Step-by-step explanation:
Given a quadratic in standard form : y = ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
y = 3x² - 12x + 17 ← is in standard form
with a = 3 and b = - 12, thus
[tex]x_{vertex}[/tex] = - [tex]\frac{-12}{6}[/tex] = 2
Substitute x = 2 into the function for corresponding value of y
y = 3(2)² - 12(2) + 17 = 12 - 24 + 17 = 5
vertex = (2, 5 )

FIND THE MIDPOINT OF THE LINE SEGMENT
Answer:
The mid point of the line segment is [tex]$ \bigg(- \frac{3}{2}, -\frac{3}{2} \bigg ) $[/tex].
Step-by-step explanation:
From the graph we can find the end points of the line segment. The end points are: [tex]$ (- 1, - 4) $[/tex] and [tex]$ (4, 1) $[/tex].
When the end points of a line segment are known, the mid point of the line segment is given by:
[tex]$ \bigg ( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \bigg ) $[/tex]
where [tex]$ (x_1, y_1) $[/tex] and [tex]$ (x_2, y_2) $[/tex] are the end points.
Here: [tex]$ (x_1, y_1) = (- 1, - 4) $[/tex] and [tex]$ (x_2, y_2) = (4, 1) $[/tex]
Therefore, the mid point of the line segment would be:
[tex]$ \bigg ( \frac{- 1 + 4}{2}, \frac{- 4 + 1}{2} \bigg) $[/tex]
[tex]$ \bigg(- \frac{3}{2}, -\frac{3}{2} \bigg ) $[/tex] is the required answer.

The age of Noelle’s dad is 6 less than 3 times Noelle’s age. The sum of their ages is 74 . Find their ages.
Answer: Noelle's age is 20 years
Noelle's father is 54 years
Step-by-step explanation: First of all, let Noelle's age be represented by x. Given that her father's age is 6 less than three times her age, her father's age would be expressed as
3n - 6
Note also that their ages sum up to 74.
Therefore,
n + (3n - 6) = 74
n + 3n - 6 = 74
4n - 6 = 74
Add 6 to both sides of the equation
4n = 80
Divide both sides of the equation by 4
n = 20
Hence, Noelle's father's age is 54 (that is 3n - 6)
While Noelle's age is 20
Noelle’s age is 20
her dads age is 54
Simplify: log81/8 + 2log2/3 - 3log 3/2 +log 3/4
Answer:
0.
Step-by-step explanation:
Using the laws of logarithms:
log81/8 + 2log2/3 - 3log 3/2 + log 3/4
= log 81/8 + log (2/3)^2 - log (3/2)^3 + log 3/4
= log 81/8 + log 4/9 - log 27/8 + log 3/4
= log 81/8 + log 4/9 - (log 27/8 - log 3/4)
= log (81/8 * 4/9) - log (27/8 * 4/3)
= log 9/2 - log 9/2
= 0.
