a boat takes 2 hours to travel 15 miles upriver against the current. if the rate of the boat in still water is 12 miles per hour. what is the rate of the current?
Answer:
7 or 8 miles per hour
Step-by-step explanation:
The rate of current or velocity of current upriver is 4.5 miles per hour.
What is velocity?Velocity is the rate of distance covered per time. Velocity could be average or instantaneous.
For example, if a car drives 50 meters for 10 seconds and it is constant then 50/10 = 5 meters/second will be the velocity.
Let's suppose the velocity or speed of the boat (Velocity in still water ) = V miles/hour
Velocity of current = x miles/hour
Given that,
The boat takes 2 hours to travel 15 miles upriver against the current.
15 miles in 2 hour
⇒ 7.5 miles/hour
Since it is traveling against the current velocity so
V - x = 7.5
And V = 12 miles/hour
By substitution,
12 - x = 7.5
x = 12 - 7.5
x = 4.5 miles/hour
Hence "The rate of current or velocity of current upriver is 4.5 miles per hour".

|-3/4+1/8|- (2/3+1/6)
Answer:
-5/24
Step-by-step explanation:
-3/4 = -6/8
-6/8 + 1/8 = -5/8
|-5/8| = 5/8
2/3 = 4/6
4/6 + 1/6 = 5/6
5/8 - 5/6 = 15/24 - 20/24
15/24 + (-20/24) = -5/24

Which of the following is equivalent to
E+f/a-d =b/a
Answer:
a is the answerStep-by-step explanation:
to understand thisyou need to know about:cross multiplicationPEMDASgiven:[tex] \frac{e + f}{a - d} = \frac{b}{a} [/tex]let's solve:[tex]step - 1 : define \\ \frac{e + f}{a - d} = \frac{b}{a} \\ step - 2 : cross \: multiplication \\ b(a - d) = a(e + f)[/tex]
The equivalent expression of (e+f)/(a-d) = b/a is a(e+f) = b(a-d). The correct option is A.
What are the equivalent expressions?Expressions that are equivalent to the same thing, even when they have distinct appearances. When we enter the same value(s) for the variable, two algebraic expressions that are equivalent have the same value (s).
Given:
An expression (e+f)/(a-d) = b/a.
To find the equivalent expression:
(e+f)/(a-d) = b/a
Using cross multiplication,
a × (e+f) = b × (a-d)
Simplifying,
a(e+f) = b(a-d).
In order to solve further, we can use the PEMDAS method.
ae + fa = ba - bd.
Therefore, a(e+f) = b(a-d) is an equivalent expression.

Answer:
1) c, f
2) a, e
3) b, d
Step-by-step explanation:
If you think about the units associated with a coordinate (feet, for example), then you may recognize the following
a) each difference is of "feet", so each difference will have units of "feet". The ratio of "feet" to "feet" cancels the units, leaving a pure number. In this case, it is called "steepness" in selection e. Steepness is given by the slope formula (2).
__
b) The difference in parentheses has units of "feet" (as in (a)), so the square will be "square feet". The sum of two of those will still be "square feet" and the square root of that will be "feet". The units of the formula are those of distance, or length, matching selection d. Distance is given by the distance formula (3).
__
c) The form shown is an ordered pair. That is the same as the representation of a coordinate point, selection f. Coordinates of a point are given by the midpoint formula (1).

Which graph represents this system of equations?
y + 2x = 3
y + 2 = 3x
Answer:
The options are not given, so i will answer in a general way.
First, we have the system:
y + 2*x = 3
y + 2 = 3*x
To graph this system, the easier way is writing both equations as linear equations, like:
y = -2*x + 3
y = 3*x - 2
Now we just need to graph these two lines in the same coordinate axis.
To do it, we can replace the value of x by two different values in each equation, and see the correspondent value of y for these values. Then graph the two points, and draw a line that connects them.
For example, for the first equation if we have x = 0, we have:
y = -2*0 + 3
y = 3
Then we have the point (0, 3)
and if x = 1
y = -2*1 + 3 = 1
y = 1
we have the point (1, 1)
Now we only need to graph these points, and draw a line that passes through them.
Once we did this for both lines, the graph we will get will look something like the one above.
And the point where the lines intersect is the solution of the system of equations.
Which is the point (1, 1)

The work of a student to find the dimensions of a rectangle of area 8 + 12x and width 4 is shown below: Step 1: 8+12x Step 2: 4(4) +4(8x) Step 3: 4(4+8x) Step 4: Dimensions of the rectangle are 4 and 4+8x In which step did the student first make an error and what is the correct step?
a. Step 2;4(2)+4x(2)
b. Step 2;4(2)+4(3x)
c. Step 3;4+(4+8x)
d. Step 3;4+(4•8x)
PLEASE LEAVE EXPLENATION!! :)
Answer:
Step (2) is incorrect.
Step-by-step explanation:
The area of a rectangle is given by :
A = length × width
Area = 8+12x
Width = 4
Step 1: 8 + 12x
Step 2: 4(2) + 4(3x)
Step 3: 4(2 + 3x)
Step 4: Dimensions of the rectangle are 4 and 2 + 3x.
It means he has done a mistake in step (2). The correct step should be 4(2) + 4(3x).
maria and emme each had 4 pints of paint on the first day of painting maria used 3/5 of her 4 pints amd emma used 3/4 of her 4 pints of paint altogether how much of maira and emma paint remained altogether how much of maria and emme paint remained after the first day of painting
HEELLPP ME PLZZZ
Answer:
[tex]\frac{13}{5}[/tex] pints of paints are left together
Step-by-step explanation:
Given
Number of pints of paint with Maria [tex]= 4[/tex]
Number of pints of paint with Emme [tex]= 4[/tex]
On the first day , Maria used [tex]\frac{3}{5}[/tex] of her [tex]4[/tex] pints of paints
Hence, Paint left after first day with Maria
[tex]= 4 - (\frac{3}{5} * 4)\\= \frac{20 - 12}{5} \\= \frac{8}{5}[/tex]
On the first day , Emme used [tex]\frac{3}{4}[/tex] of her [tex]4[/tex] pints of paints
Hence, Paint left after first day with Emme
[tex]= 4 - (\frac{3}{4} * 4)\\\\= 4-3\\= 1[/tex]
Total pint of paint left with both Maria and emme altogether
[tex]= 1 + \frac{8}{5}\\= \frac{5+8}{5} \\= \frac{13}{5}[/tex]
The graph of the reciprocal parent function, f(x) = 1, is shifted 5 units up
and 8 units to the left to create the graph of g(x). What function is g(x)?
Answer:
A. 1/(x + 8) + 5.
Step-by-step explanation:
Staring with 1/x a shift up of 5 units makes it 1/x + 5.
A shift of 8 to the left makes it 1/(x + 8) + 5
