Step-by-step explanation:
Container I currently contain 4.6 gallons of water and is being filled at a rate of 1.2 gallons per minute. Container II currently has 54.6 gallons of water and is being drained at a rate of 0.8 gallons per minute. After how many minutes will both containers have the same amount of water?
Answer: After 25 minutes both containers will have the same amount of water.
Step-by-step explanation:
Let x = Number of minutes
y= Quantity of water
For container I, Quantity of water will be :
y = 4.6+ 1.2x
For container II, Quantity of water will be :
y = 54.6-0.8x
According to the question, we have
4.6+ 1.2x = 54.6-0.8x
Add 0.8x on both sides and subtract 4.6 on both sides , we get
1.2x+8x = 54.6-4.6
⇒ 2x = 50
Divide both sides by 2, we get
x= 25
So after 25 minutes both containers will have the same amount of water.

In an apartment building, there is only one elevator that residents are allowed to use. The elevator picks up six people in the main lobby and ascends 4 floors. Next, the elevator ascends another 2 floors and descends 3 floors. The elevator ascends 8 more floors, then descends 2 floors. The elevator finally descends another 2 floors before getting stuck. What floor is the elevator stuck on?
Answer:
It is stucked on the 9th floor
Step-by-step explanation:
We want to know the floor on which the elevator is stucked.
The main lobby is the ground floor and has a value of 0 floor
Ascends four floors with 6 people from the lobby
It is now on floor 4
Ascends another two so it is now on floor 4 + 2 = 6
Ascends another 2, then descend descends 3
That will be 6 + 2 -3 = 5th floor
Ascends 8 more , then descend 2
That will be 5 + 8 -2 = 11
Descends another 2, making 11 - 2 = 9
It is stucked on floor 9
Kindly note, when it ascends, that is a positive value, when it descends, that is a negative

Find the values of x and y. 3x - 5 5y - 4 y + 12
The values of x and y in the equilateral and Isosceles triangles are 7 and 4 respectively.
What is an equilateral triangle?An equilateral triangle is a triangle that has all its sides equal to each other.
Therefore,
3x - 5 = 5y - 4 (equilateral triangle)
3x - 5y = 1
Therefore,
y + 12 = 3x - 5 (Isosceles triangle)
y - 3x = - 17
Hence,
3x - 5y = 1
- 3x + y = - 17
-4y = -16
y = -16 / -4
y = 4
Therefore,
3x = 1 + 5(4)
3x = 21
x = 21 / 3
x = 7

Write an equation in slope-intercept form that goes through the points (4, 4) and (1, 2).
Step-by-step explanation:
Hey there!
The given points are; (4,4) and (1,2) as (x1,y1) and (x2,y2).
Note: Use double point formula for the equation.
Now;
[tex](y - y1) = \frac{y2 - y1}{x2 - x1} (x - x1)[/tex]
Put all values.
[tex](y - 4) = \frac{2 - 4}{1 - 4} (x - 4)[/tex]
Simplify it.
[tex](y - 4) = \frac{ - 2}{ - 3} (x - 4)[/tex]
[tex](y - 4) = \frac{2}{3} (x - 4)[/tex]
[tex](y - 4) = \frac{2}{3} x - \frac{2}{3} \times 4[/tex]
[tex]y = \frac{2}{3}x - \frac{8}{3} + 4 [/tex]
[tex]y = \frac{2}{3} x - \frac{8 + 12}{3} [/tex]
[tex]y = \frac{2}{3} x + \frac{4}{3} [/tex]
Therefore, the equation is; y = 2/3x+4/3.

Answer:
D
Step-by-step explanation:
The numbers between the < , > show the change from the preimage to the image. So, <-2,3> would be the x - 2 and the y + 3.
So, A(5,6) -> A'(3,9)
B(6,-3) -> B'(4,0)
C(7,2) -> C'(5,5)
A middle school took all of its 6th grade students on a field trip to see a ballet at a theater that has 4200 seats. The students filled 84% of the seats in the theater. How many 6th graders went on the trip?
You need to find 84% of 4200 to get the amount of students. First change the percent to a decimal, and multiply 0.84 x 4200.
There were 3528 total students at the theater.

Food bank usage in Britain has grown dramatically over the past decade. The number of users, in thousands, of the largest food bank in year t is estimated to be N(t) = 1.3e0.81t , where t is the number of years since 2006.25
(a) What does the 1.3 represent in this context? Give units.
(b) What is the continuous growth rate of users per year?
(c) What is the annual percent growth rate of users per year?
(d) Using only your answer for part (c), decide if the doubling time is more or less than 1 year.
Answer:
A) 1.3 represents the number of foodbank users in thousands in the year 2006
B) 0.81 per year
C) 124.79%
D) the doubling rate is less than a year.
Step-by-step explanation:
A) We are given N(t) = 1.3e^(0.81t) where t in thousands the number of years since 2006. N(t) is in thousands
Thus, in 2006,t = 0.
So, N(0) = 1.3e^(0.81 × 0)
N(0) = 1.3
Thus,1.3 represents the number of foodbank users in thousands in the year 2006
B) From the question, we see that the continuous growth rate is 0.81t.
This is 0.81 per year
C) The exponent of the growth rate is e^(0.81t).
Thus gives; 2.2479^(t)
This means the annual growth factor for each year is 2.2479.
Thus,annual percent growth rate is;
(2.2479 - 1) × 100% = 124.79%
D) From C above we saw that the annual percent growth rate is more than 100%. This means that it takes less than a year for the number of users to be doubled.. Thus, the doubling rate is less than a year.

Mr. Tonroy hired Michael to make balloon animals for the children who visited a carnival. Michael was paid a base fee of $100.00 plus a fee of $1.50 per balloon animal made. If Michael was paid $295.00, how many balloon animals did Michael make is to be determined
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
Here,
Let the number of the balloons be x,
According to the question,
295 = 100 + 1.5x
1.5x = 295 - 100
1.5x = 195
x = 195 / 1.5
x = 130
Thus, the required number of balloons animals Michael made is 130.

Given the functions f(x) = 2x2 +5 and g(x) = 8+x find go f(-5)
A. 63
B.3.
C.2
D.23
Answer:
A. 63
Step-by-step explanation:
Given functions:
f(x) = 2x² + 5
g(x) = 8 + x
find:
g o f(-5)
Solution:
Start first by finding f(-5);
f(x) = 2x² + 5
= 2(-5)² + 5
= 50 + 5
= 55
Now
g o f(-5);
g(55) = 8 + 55 = 63
If on a scale drawing 240 feet
are represented by 10 inches,
then a scale of ¼ inch
represents how many feet?
Answer:
6 feet
Step-by-step explanation:
240 feet : 10 inches
24 feet : 1 inch
? feet : 1/4 inch
to get from 1 to a 1/4 you divide by 4, so you do 24 ÷ 4
24 ÷ 4 = 6
Answer:
6 ft
Step-by-step explanation:
First, make this visually understandable using a ratio:
240 ft = x ft
10 in [tex]\frac{1}{4}[/tex] in
To find the change between the inches,
1/4 ÷ 10 = 0.025
Use this same amount to find x ft:
240 (0.025) = 6
x = 6 ft
To double-check:
240/10 = 24
6/0.25 = 24
