Answer:
1.75 liters
Step-by-step explanation:
We know that all 200 bottles can hold 350 liters of water.
Suppose each bottle holds b liters of water. Then we can model the situation in terms of b:
200b = 350
Divide both sides by 200:
b = 350/200 = 35/20 = 1.75
The answer is thus 1.75 liters.

Two identical pumps fill a water reservoir in 10 hours. How many additional pumps should be turned on if the reservoir must be willed in 4 hours?
Answer:
5
Step-by-step explanation:
All you have to do is 2*10=20 and then 20/4=5
So 5 additional pumps should be turned on.
The number of additional pumps that should be turned on if the reservoir must be filled in 4 hours is 3 pumps
Given:
2 identical pumps = 10 hours
Time taken for each pump = Total time ÷ number of pumps
= 10 hours / 2 pumps
= 5 hours per pump
Total hours to fill a reservoir = 4 hours
let
x = number of pumps
Number of pumps = (Time taken for each pump × Total hours to fill a reservoir) / Total hours to fill a reservoir
= (5 × 4) / 4
= 20 / 4
= 5 pumps
Additional pump needed = Pumps needed - available pumps
= 5 - 2
= 3
Therefore, number of additional pumps that should be turned on if the reservoir must be filled in 4 hours is 3

Based on a survey, assume that 38% of consumers are comfortable having drones deliver their purchases. Suppose that we
want to find the probability that when four consumers are randomly selected, exactly two of them are comfortable with
delivery by drones. Identify the values of n, x, p, and q.
Answer:
[tex]n = 4[/tex]
[tex]x = 2[/tex]
[tex]p = 38\%[/tex]
[tex]q = 62\%[/tex]
Step-by-step explanation:
Required
Find n, x, p and q
n always represent the population surveyed;
So:
[tex]n = 4[/tex]
x represents the sample from the population
So:
[tex]x = 2[/tex]
p always represents the given proportion
[tex]p = 38\%[/tex]
Solving for q
[tex]p + q = 1[/tex]
[tex]q = 1 - p[/tex]
[tex]q = 1 - 38\%[/tex]
[tex]q = 62\%[/tex]

Owning a small and successful business isn't easy! There is a monthly cost of shipping supplies and
products of $2000. There is also a monthly cost of $1600 for each employee you hire. If you hire x
employees for the year, what is the total cost, C, in dollars, to keep your business running?
Answer:
[tex]C(x)=24,000+19,200x[/tex]
Step-by-step explanation:
Mathematical Modeling
To model a real-life situation, a mathematical model can be constructed in such a way it accurately represents the variables measured in the system.
This problem requires to build a model for the yearly cost of a small and successful business.
The first data is the fixed monthly cost or the money the owner must pay regardless of the number of employees he hires. This cost includes shipping supplies and products for $2,000. To operate for a full year, the fixed cost is 12*$2,000=$24,000.
The other component of the cost function is the variable cost of x employees. Given each employee costs $1,600 each month, having x employees cost 1,600x each month. For a full year, the variable cost will be
12*1,600x=19,200x.
We finally form the total cost function:
[tex]\boxed{C(x)=24,000+19,200x}[/tex]

In the figure, RS bisects DE at point s. DS = 3x + 10 and SE = 6x - 2. Find the value of 'x and the length
of the segment DE.
x = 4; DE = 22
x = 8/3; DE = 18
x = 4; DE = 44
X = 3; DE = 38
The value of x is equal to 4 and the length of segment DE is equal to 44.
Option (C) is correct.
It is required to find the scientific notation.
What is midpoint ?The midpoint is the middle point of a line segment. It is equidistant from both endpoints, and it is the centroid both of the segment and of the endpoints. It bisects the segment.
Given:
Since S is the midpoint of line segment DE, it simply means that line segment DE is divided into two (2) sections DS and SE and they are equal in length. By applying the midpoint rule, we have:
DS = SE
3x + 10 = 6x - 2
6x - 3x = 10 + 2
3x = 12
x = 12/3
x = 4.
For the measure of segment DS, we have:
DS = 3x + 10
DS = 3(4) + 10
DS = 12 + 10
DS = 22.
For the measure of segment SE, we have:
SE = 6x - 2
SE = 6(4) - 2
SE = 24 - 2
SE = 22.
For the measure of segment DE, we have:
DE = DS + SE
DE = 22 + 22
DE = 44.
Therefore, the value of x is equal to 4 and the length of segment DE is equal to 44.

Answer:
See step by step explanation or see diagram.
Step-by-step explanation:
Hi!
So, we're asked to find a line that is parallel to the given line and passes through a point.
We're going to use slope-intercept form.
y=mx+b
M is slope and b is y-intercept
Start!: Find a line that is parallel to y= -2x +4 and passes through (-4,7)
Parallel lines have the same slope . We can change slope-intercept form to reflect that.
y=-2x + b
Now, we need to find b (the y-intercept). We can do this by plugging in the coordinates of the point that we were given.
7= -2 (-4) + b
7 = 8 +b
b = -1
Next, change the equation to reflect that.
y = -2x - 1.
So, go right.
This time, the point is (2,1) and the line is y= -x - 4.
The slope of a line parallel to y = -x -4 is -1.
y= -1x+b
Plug in the points:
1 = -1 (2) +b
1 = -2 +b
b = 3
Finish the equation.
y = -x + 3.
Go diagonally.
This time, the point is (-6,1) and the line is y = 1/2x +1 .
The slope of the parallel line will be 1/2.
y= 1/2x +b
Plug in points:
1 = 1/2 (-6) + b
1 = -3 +b
b = 4
y = 1/2x + 4
Go down.
This time, the point is (2,0) and the line is y= 3/2x+5
Slope of parallel line: 3/2
y = 3/2x+b
Subsitute points in.
0 = 3/2(2) + b
0 = 3 + b
b = -3
y = 3/2x -3
Go left.
This time, the point is (-1,-5) and the line is y=2x-9
Slope of parallel line: 2
y=2x+b
Substitute points:
-5 = 2(-1) + b
-5 = -2 + b
b = -3
y= 2x -3
Go diagonally.
This time, the point is (-9, -8) and the line is y= 1/3x+3
Slope of parallel line: 1/3
y = 1/3x+b
-8 = 1/3 (-9) +b
-8 = -3 +b
b= -5
y=1/3x-5
Go up.
This time, the point is (4,3) and the line is y= x +6
SOPL (slope of parallel line): 1
y=x+b
3 = 4 + b
b = -1
y=x-1
Go right.
This time, the point is (-2, -8) and the line is y=3x-1
SOPL = 3
y= 3x+b
-8 = 3(-2) +b
-8 = -6 + b
b = -2
y=3x-2
Go down.
This time, the point is at (1,4) and the line is y=-2x-1
SOPL: -2
y= -2x + b
4 = -2 (1) +b
4 = -2 + b
b=6
y= -2x + 6
Go diagonally.
This time, the point is (4,11) and the line is y = -1/2x-5
SOPL: -1/2
y= -1/2x + b
11 = -1/2 (4) +b
11 = -2 +b
b=13
y= -1/2x+13
Finish!
What is the slope of the line that passes through the points (5, 2) and (-3, 6)?
Answer:
-1/2
Step-by-step explanation:
We can use the slope formula
m = ( y2-y1)/(x2-x1)
