Answer:
[tex]v = \frac{5.4mT}{6T - 37}[/tex]
[tex]v = -1.701*10^8[/tex]
Step-by-step explanation:
Given
[tex]T = \frac{37v}{6v-5.4m}[/tex]
Solving (a): Make v the subject
[tex]T = \frac{37v}{6v-5.4m}[/tex]
Cross Multiply:
[tex](6v-5.4m)T = 37v[/tex]
Open bracket
[tex]6vT - 5.4mT = 37v[/tex]
Collect Like terms
[tex]6vT - 37v= 5.4mT[/tex]
Factorize:
[tex](6T - 37)v= 5.4mT[/tex]
Make v the subject
[tex]v = \frac{5.4mT}{6T - 37}[/tex]
Solving (b):
[tex]T = 4.5[/tex]
[tex]m = 7 * 10^7[/tex]
So, the expression becomes:
[tex]v = \frac{5.4mT}{6T - 37}[/tex]
[tex]v = \frac{5.4*7*10^7*4.5}{6*4.5 - 37}[/tex]
[tex]v = \frac{170.1*10^7}{27 - 37}[/tex]
[tex]v = \frac{170.1*10^7}{-10}[/tex]
[tex]v = -17.01*10^7[/tex]
[tex]v = -1.701*10*10^7[/tex]
[tex]v = -1.701*10^8[/tex]

A bridge being designed will cross the river at a right angle. The equation of the left bank of the river is j = 2x+8. The center of the bridge will pass through (0,2). What is the equation of the line representing the bridge?
This is the same as y = -0.5x+2
==========================================================
Explanation:
Refer to the diagram below.
The blue line is the graph of y = 2x+8, which is the left bank of the river.
For now, ignore the y = (-1/2)x+2 in the diagram and pretend we don't know that just yet. The red line is the bridge and it's some linear equation in the form y = mx+b. We're told the bridge is perpendicular to the river, so the bridge must also be perpendicular to the riverbank.
The blue line has slope m = 2. Apply the negative reciprocal to this to end up with -1/2. This is the perpendicular slope, and the slope of the red line. Note how the two slopes (2 and -1/2) multiply to -1. Any two perpendicular lines will have their slopes multiply to -1, as long as neither line is vertical or horizontal.
Since we want the bridge to pass through (0,2), this must mean the y intercept is b = 2.
So with m = -1/2 and b = 2, we go from y = mx+b to y = (-1/2)x + 2 which is the equation of the bridge shown in red.
This is the same as y = -0.5x + 2 since -1/2 = -0.5

Jackie has one sister. Jackie's sister is 4 years older than her. The girls' ages add up to 28. Write an equation to solve for Jackie's age. *
Answer:
Jackie's age = 12 years and Her sister's age = 16 years
Step-by-step explanation:
Let the age of Jackie be x.
Her sister's age = (x+4)
The sum of ages = 28
ATQ,
x+x+4 = 28
2x+4 = 28
2x = 24
x = 12
Jackie's age = 12 years
Her sister's age = (12+4) = 16 years
Hence, this is the requiredsolution.

How do you graph (0,3.5)
Answer:
In a coordinate axis, the horizontal line is called the x-axis, and the vertical line is called the y-axis.
1) Then if you have a point (x, y), to graph this you go at the horizontal axis to find the value x,
2) Starting from the point you already found, now you need to move y units in the vertical axis.
Now we want to graph the point (0, 3.5).
First we need to locate the value 0 in the horizontal axis, this is the point where both axes intersect.
Now we move 3.5 units, because the number is positive, we move 3.5 units upwards.
The graph of the point is shown below.

what is an indulgence?
Answer:
In the teaching of the Catholic Church, an indulgence is "a way to reduce the amount of punishment one has to undergo for sins".
Answer:
In the teaching of the Catholic Church, an indulgence is "a way to reduce the amount of punishment one has to undergo for sins"
Step-by-step explanation:
Indulgence is the action or fact of indulging. (in the Roman Catholic Church) a grant by the Pope of remission of the temporal punishment in purgatory still due for sins after absolution. The unrestricted sale of indulgences by pardoners was a widespread abuse during the later Middle Ages.
Indulgence sentence example. The indulgence accentuated the division between those who accepted and those who rejected it. German chocolates are my only indulgence . I went to a party last night, and there out of five ladies three were Roman Catholics and had the Pope's indulgence for doing woolwork on Sundays.
Find the missing side length of the right triangle. Be sure to clearly identify
which side is the hypotenuse first. 50 yards and 30 yards
Answer:
40 yards
Step-by-step explanation:
Let the hypotenuse = 50yards
Adjacent = 30yeards
The missing length is x
Using the pythagoras theorem
hyp^2 = opp^2 + adj^2
50^2 = 30^2 + x^2
2500 = 900 + x^2
x^2 = 2500 - 900
x^2 = 1600
x = √1600
x = 40yards
Hence the length of the missing side is 40 yards
How many solutions exist for the given equation?
1/2(x + 12) = 4x-1
zero
one
two
infinitely many
Answer:
one
Step-by-step explanation:
Given
[tex]\frac{1}{2}[/tex] (x + 12) = 4x - 1 ( multiply through by 2 to clear the fraction )
x + 12 = 8x - 2 ( subtract x from both sides )
12 = 7x - 2 ( add 2 to both sides )
14 = 7x ( divide both sides by 7 )
2 = x
There is one solution to the equation, that is x = 2

length = 25cm, bredth =60 cm, Volume = 7500cm^3. Find height of a cuboid.
Answer:
height = 5cm
Step-by-step explanation:
Volume of the cuboid = length x breadth x height
7500 = 25 x 60 x height
height = 7500 / 1500
height = 5
Answer:5
Step-by-step explanation:
V = l×b×h
h = 7500 ÷ (25×60)
h = 5

1. When Jack and Jill work together, they can carry a cooler of
water up a hill in 12 hours. When Jill works alone it takes her
7 fewer hours than when Jack works alone. How long would it
take Jack, working alone, to carry a cooler of water up a hill?
9514 1404 393
Answer:
28 hours
Step-by-step explanation:
Let x represent Jack's time. Then Jill's is x-7. Together their rate of carrying water in hills per hour is ...
1/x + 1/(x -7) = 1/12
Multiplying by 12x(x -7) gives ...
12(x -7) +12x = x(x -7)
x^2 -31x +84 = 0 . . . . . subtract the left side and simplify
(x -3)(x -28) = 0 . . . . . . . . . . factor
x = 3 or x = 28 . . . . . . . . . . x-values that make the factors zero
We know the times must be longer than 12 hours, so the value x=3 is extraneous for this problem.
It takes Jack 28 hours to carry the cooler of water up the hill working alone.

Select all expressions equivalent to 6x- - 24.
Answer:
the answer should/could be 6(x-4) & 3(2x-8)
Answer:
6(x - 4) & 3(2x - 8) is the answer
Step-by-step explanation:
6(x - 4) = 6x - 24
2(3x - 24) = 6x - 48
3(2x - 8) = 6x - 24
3(3x - 21) = 9x - 63
Which of these statements are correct about a line segment with a length of 12 units in a coordinate plane? Select all that apply. If it is rotated 270° about the origin, its length will still be 12 units. If it is rotated 90° about the origin, its length will no longer be 12 units. If it is reflected across the line y = –x, its length will no longer be 12 units. If it is translated 18 units to the right, its length will no longer be 12 units. If it is translated 15 units up, its length will still be 12 units. If it is reflected across the y–axis, its length will still be 12 units.
