Container A and container B have leaks. Container A has 800 ml of water, and is
leaking 6 ml per minute. Container B has 1000 ml, and is leaking 10 ml per minute.
How many minutes will it take for the two containers to have the same amount of
water?
**Write an equation to represent the situation (first blank). Use the variable m, for
minutes.
**Then solve for m (second blank).
**Finally, use your solution to determine the water level at that time (third blank).
The equation
can represent this situation. It will take
minutes for the two containers to have the same amount of water. At this time,
both containers will have ml left.
Answer:
a) 50 minutes
b) The water level at 50 minutes for Container A and B would be 500ml
Step-by-step explanation:
a) Let number of minutes at which both containers leak be represented by m.
Container A has 800 ml of water, and is leaking 6 ml per minute.
800ml - 6ml × m
800 - 6m
Container B has 1000 ml, and is leaking 10 ml per minute.
1000ml - 10ml × m
1000 - 10m
How many minutes will it take for the two containers to have the same amount of water?
Container A = Container B
800 - 6m = 1000 - 10m
Collect like terms
-6m + 10m = 1000 - 800
4m = 200
m = 200/4
m = 50 minutes
It will take 50 minutes for the two containers to have the same amount of water.
b) Finally, use your solution to determine the water level at that time.
Since m = 50 minutes
Container A = Container B
800 - 6m = 1000 - 10m
800 - 6 × 50 = 1000 - 10 × 50
800 - 300 = 1000 - 500
500 ml = 500 ml
Therefore, the water level at 50 minutes is 500 ml
Find the equation of the line that passes through points a and b.

Answer:
y=2x-1
Step-by-step explanation:
Gradient : (7-3) / (4-2) = 2
y=2x+c
substitute one of the points
3=2*2+c
c=-1
y=2x-1
calculate each
!!!!!!!!!
Step-by-step explanation:
1. (4m² - 1.5m + 2) + (9m - 2m³ + 2m)
= 4m² - 1.5m + 2 + 9m - 2m³ + 2m
= 4m² + (-1.5m + 9m + 2m) + 2 + 2m³
= 4m² + 9.5m + 2 + 2m³
= 2m³ + 4m² + 9.5m + 2
2. (-3y + 2y² - 6) + (3y + 4y² + x)
= -3y + 2y² - 6 + 3y + 4y² + x
= (-3y + 3y) + (2y² + 4y²) - 6 + x
= 0y + 6y² - 6 + x
= 6y² - 6 + x
which point is collinear to the point (0,0)?
A) (1,0)
B) (3,2)
C) (4,1)
D) (1,3)
Answer:
All of them are right
Step-by-step explanation:
Are you sure the question was that?
Collinear means that it lies on the same line
Now, from every 2 points passes a unique line
So(0,0) and (3,2) are in a line
(0,0) and (1,0) are in an other line and so on

y-2 = -3(x + 6), write the equation of the line in slope intercept form.
Answer:
y = -3x - 16
Step-by-step explanation:
Point-slope form: y - y1 = m(x - x1)
Given: y - 2 = -3(x + 6)
Slope-intercept form: y = mx + b
To write the equation in slope-intercept form, we need to know the slope(m) and the y-intercept(b). By looking at the given equation, we can see that the slope is -3. We are also given the value of one point: (-6, 2).
To find the y-intercept, input the given values of the slope and the point into the equation format and solve for b:
y = mx + b
2 = -3(-6) + b
2 = 18 + b
Subtract 18 from both sides of the equation to isolate b:
2 - 18 = 18 - 18 + b
-16 = b
The y-intercept is -16.
Now that we know the slope and the y-intercept, we can write the equation:
y = -3x - 16
four ninths plus nine eighteenths :]
Answer: 17/18
In words, this is seventeen eighteenths
==========================================
Work Shown:
4/9 + 9/18
8/18 + 9/18 ... see note below
(8+9)/18
17/18
----------------
note: To go from 4/9 to 8/18, we multiply top and bottom by 2. So that's why 4/9 = 8/18.
The diagram below shows a visual representation of why 4/9 = 8/18.
In the top row, I've drawn out 9 rectangles of the same size. Then I've shaded 4 of the 9 rectangles to represent the fraction 4/9. In the bottom row, I've cut each of those 9 rectangles into two smaller equal pieces, so we have 9*2 = 18 rectangles now. Note how the shaded regions are the same size, so this shows 4 green regions doubles to 2*4 = 8 yellow regions; therefore 4/9 is the same as 8/18.
Answer: its 17/18

18. Two planes left an airport at the same time. One flew north at a set speed and the other
flew south at one-and-a-half times the speed of the other plane. Three hours later the planes
were 2400 miles apart. How fast was each plane flying?
Answer: plane A = 333.33mph
Plane B = 500mph
Step-by-step explanation:
Given data:
Distance between the two planes = 2400miles.
Plane A flew North
Plane B flew south
Solution:
Let v represent plane A.
Let 2v represent plane B.
Distance between the two plane
v + 1.5* v = 3*v
7.5v = 2500miles
v = 333.33mph
Plane B has one and half times the speed of plane A
= 1.5 * 333.33
= 500mph

Answer:
42
Step-by-step explanation:
[tex]41^{2}[/tex] + [tex]9^{2}[/tex] = [tex]c^{2}[/tex]
So, what's 41 to the power 2?
Thus;
1,681
Do the same for the other one.
9 to the power of 2
Thus;
81
Add all these up all your final answer to get a total of 1,762.
1681+81=1762
Thus;
[tex]c^{2} = 1762[/tex]
Then square root your final answer
[tex]\sqrt[]{1762}[/tex]=[tex]c^{2}[/tex]
Thus;
42= [tex]c^{2}[/tex]

Which could be a step used when solving the equation 2x−5=1/3x
Answer:
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
x = 3
Step-by-step explanation:
Multiply both sides by 3. I take it mean 1/3 * x and not 1/(3*x) which puts x in the denominator.
6x - 15 = (1/3) x * 3 Cancel on the right.
6x - 15 = x Subtract 6x from both sides.
6x - 6x - 15 = x - 6x Collect light terms
- 15 = - 5x Divide by - 5
-15/-5 = -5x/-5
x = 3

I need help with solving for x please
Answer:
1. x = 16
2. 2x + 9 = 41
Step-by-step explanation:
So this is the first step.
2x + 9 + 3x + 1 = 90 (collect like terms)
5x + 10 = 90 (subtract 10 on both sides)
5x = 80 (divide by 5 on each side)
x = 16
Plug in to 2x + 9
2(16) + 9 =
32 + 9 =
41 = 2x + 9

Weights of different materials were taken for three lengths: 6 inches, 12 inches, and 18 inches. Which of the materials' weights does NOT have a proportional relationship with length?
The question is incomplete, the complete question is shown in the image attached.
Answer:
Material 1
Step-by-step explanation:
Given the table shown in the complete question, we can see that the weights in material 1 does not have a proportional relationship with length.
If something has a proportional relationship, then it increases or decreases by a constant value called the constant of proportionality. This is not the case in material 1 as seen from the table.
