Irma and Kate have summer jobs selling newspaper subscriptions door-to-door, but their
compensation plans are different. Irma earns a base wage of $15 per hour, as well as $1 for
every subscription that she sells. Kate gets $2 per subscription sold, in addition to a base
wage of $6 per hour. If they each sell a certain number of subscriptions in an hour, they will
end up earning the same amount. How many subscriptions would that be? How much would
each one earn?
If Irma and Kate sell
subscriptions in an hour, they will each earn $
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
Jerry played with friends today, all at different times. He played with Tommy for hours, then Nathan for hours, then Chris for hours.
How many hours did Jerry play with his friends today?
Answer:
twelve hours
Step-by-step explanation:
Answer:
Undefined
Step-by-step explanation:
You told us that Jerry played with all of his friends for hours. You did not give us a specific number of hours for at least two of them. Therefore, we can conclude nothing.
It is undefined.
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.

area of square = 100
area of circle = 15.7
the area of the shaded = im not really sure but im thinking its 50
Step-by-step explanation:
so u see the line in the middle it say 10 cm and the square is equal on all sides so it would be 10cm for the lenth and with so it would be 10 times 10 witch is 100 and u would use the 10 for the circle aswell witch u would use 3.14 times 10 divided by 2 to get the area of the circle
Answer:
The Area of the square is 100cm^2
The Area of the Circle is 78.54cm^2
The Area of the Yellow is 21.46cm^2

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.

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
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.

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.
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.
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
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
