a streamer going downstream in a river cover the distance between two towns in 15 hours coming back upstream it covers the distance in 20 hours the speed of the water is 3 kilometre per hour . find the distance between two towns
Answer:
360 km
Step-by-step explanation:
Let stream speed = x
Speed of water = 3km/hr
Therefore,
Upstream speed = (x - 3) km/hr
Downstream speed = (x + 3) km/hr
Time taken downstream = 15 hours
Time taken upstream = 20 hours
Recall:
Distance = speed * time
Upstream Distance = downstream distance
20(x - 3) = 15(x + 3)
20x - 60 = 15x + 45
20x - 15x = 45 + 60
5x = 105
x = 105 / 5
x = 21
Upstream speed = (21 - 3) = 18
Distance between the two towns :
18 * 20 = 360 km
Solve 3[-x + (2x+ 1)] =X- 1.

Find the distance between the two points rounding to the nearest tenth (if necessary).
(4,2) and (1, -2)
Answer:
5 units
Step-by-step explanation:
Calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (4, 2) and (x₂, y₂ ) = (1, - 2)
d = [tex]\sqrt{(1-4)^2+(-2-2)^2}[/tex]
= [tex]\sqrt{(-3)^2+(-4)^2}[/tex]
= [tex]\sqrt{9+16}[/tex]
= [tex]\sqrt{25}[/tex]
= 5

PLEASE HELP I NEED THIS ANSWER
Answer:
E
Step-by-step explanation:
Since the value of x is 10 and the value of y is -2, we can plug it into the equation for E. -2 = -1/5(10) which makes it -2=-2 which is true.
Step-by-step explanation:
For every 10 units across (0 to 10),
the line decreases by 2 units (0 to -2).
Slope of line
= Rise / Run = (-2) / (10) = -1/5.
Also the y-intercept of the line is 0
as it passes through the origin.
Hence the equation is y = -1/5 x. (E)

Consider the following pieces of identification a person might have in order to apply for a credit card:
B : Applicant present a birth certificate
D: Applicant presents a drivers license
M applicant presents a marriage license
Write Logical expressions
1. The applicant must present either a birth certificate, a drivers license or a marriage license.
2. The applicant must present any two of the following forms of identification: birth certificate, drivers license, marriage license
3. Applicant must present either a birth certificate or both a drivers license and a marriage license
Answer:
B v D v M ;
(B ٨ M) V (B ٨ D) V (M ٨ D) ;
B V (D ٨ M)
Step-by-step explanation:
Given :
B : Applicant present a birth certificate
D: Applicant presents a drivers license
M applicant presents a marriage license
1.)
This means that any one of the three must be presented :
Birth certificate OR Driver's license OR Marriage certificate
B v D v M
2.)
This means any two combination of the three certificates :
(birth certificate and marriage certificate) OR (birth certificate and driver's license) OR (marriage certificate and driver's license)
(B ٨ M) V (B ٨ D) V (M ٨ D)
3.)
That is birth certificate alone will suffice or a driver's incense and a marriage certificate
B V (D ٨ M)
Translate the statement into an algebraic expression. (Use "w" as a variable. Do not use "$" in your answer.
Mike had $184 and he is earning $50 per week.
Answer:
Cost = 184+50w
Step-by-step explanation:
Given statement is "Mike had $184 and he is earning $50 per week".
Here, $184 is fixed and $50 increases per week.
Let w is the variable.
ATQ,
Cost = 184+50w
Hence, the algebraic expression for the given statement is 184+50w.
what number are even and wich numbers are odd?
Answer:
Numbers 1, 3, 5, 7, and 9 and so on are uneven. These are only up to ten. Numbers 0, 2, 4, 6, 8, and 10 are even. If 0 is even just skip one number (you skip 1) and the number after (which is 2) is even and you continue so. For uneven numbers you do the same you start from 1 then skip a number (which is 2) and end up with 3 and you also co tune onward for this. I hope it helps!

simplified expression for
3(2x + 1) - 2(4x - 1)
A. 2x + 1
B. -2x + 5
C. -X + 5
D. 14x + 1
E. 14x - 1
Answer:
B. -2x + 5
Step-by-step explanation:
First, distribute the 3 and 2 to the parentheses:
3(2x + 1) - 2(4x - 1)
6x + 3 - 8x + 2
Add like terms:
-2x + 5
So, the simplified expression is -2x + 5

A pizza shop sells three sizes of pizza, and they track how often each size gets ordered along with how much they profit from each size. Let X represent the shop's profit on a randomly selected pizza. Here's the probability distribution of XXX along with summary statistics:
Small Medium Large
X= Profit($) 4 8 12
P(X) 0.18 0.50 0.32
Mean μx= $8.56
Standard Deviation σx ≈ 2.77
The company is going to run a promotion where customers get $2 off any size pizza. Assume that the promotion will not change the probability that corresponds to each size. Let Y represent their profit on a randomly selected pizza with this promotion. What are the mean and standard deviation of Y?
Answer:
μy = $6.56 ; σy = 2.77
Step-by-step explanation:
Given the data :
Mean μx= $8.56
Standard Deviation σx ≈ 2.77
Profit, Y on pizza with current promo :
Price off on pizza = $2
Y = x - 2
μx = E(x) = $8.56
μy = μ(x - 2)
μy = μx - $2
μy = $8.56 - $2
μy = $6.56
For the standard deviation of y
σx ≈ 2.77
σy = σ(x - 2)
σy = σx - 2
Constants are treated as 0 for standard deviation
σy = 2.77

A line with slpoe 3 passes through the point (0.10). What is the y-coordinate of the point on the line with x-coordinate 2
Answer:
When x-coordinate x = 2, the value of the y-coordinate is: y = 16
Please also check the graph.
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptGiven
The point (0, 10)
The slope m = 3
The value of the y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
We have given the point (0, 10)
It means:
at x = 0, y = 1 0
Therefore, the y-intercept b = 10
so substituting b = 10 and m = 3 in the slope-intercept form
[tex]y = mx+b[/tex]
[tex]y = 3x+10[/tex]
Therefore, the equation of a line with slope 3 passes through the point (0, 10) will be:
[tex]y = 3x+10[/tex]
Now, substituting x = 2 in the equation
[tex]y = 3x+10[/tex]
y = 3(2) + 10
y = 6+10
y = 16
Therefore, when x-coordinate x = 2, the value of the y-coordinate is: y = 16
Please also check the graph.

Answer:
(x, y ) → (x + 10, y + 10 )
Step-by-step explanation:
Consider the coordinates of C and C'
C(- 7, - 1 ) and C'(3, 9 )
The translation in the x- direction is
- 7 → 3 = 3 - (- 7) = 3 + 7 = 10
The translation in the y- direction is
- 1 → 9 = 9 - (- 1) = 9 + 1 = 10
Then translation rule is
(x, y ) → (x + 10, y + 10 )
Which equation is a linear function?
y= 2 + 3
y = 22 - 1
y= 22 +7
A band expects to put 16 songs on their next CD. The band writes and records 37.5% more songs than they expect to put on the CD. During the editing process, 50% of the songs are removed. How many songs will there be on the final CD?
answer:
- this is multi-step problem
16 X 1.375 = 22 songs (37.5% was added)
22 X .5 = 11 songs (50% was removed)
