what is an indulgence?​

Answers

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.

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?

Answers

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.

we can make some assumptions b/c of the marks. on the sides,  the double marks means they are the same,  and the single marks are also the same length.  because those sides are the same lengths.. we can just add up all the  sides to find the length around the shape... or the perimeter of it.  

Step-by-step explanation:

I'll start with the 14 on the left, and go counter clock wise

14 + 6 + 9 + 5 + 9 + 7 + 14 + (6+7+5)   =  Perimeter

the last numbers in the parenthesis are from the sides opposite of the long top side,  the parts of the other sides adds up to the long top side... sooo,

Perimeter = 82   ( I added in my head , so use a calculator to double check )

How do you graph (0,3.5)

Answers

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.

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

Answers

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

If a shirt cost 9.99, but there was a sale that said 15% of the original price, how much was the shirt?

Answers

Answer: $8.49

To solve this problem, you want to find out how much 15% of 9.99 is. To do that you have to multiply 9.99 by 0.15 (which equals 1.4985) to find out how much the shirt was discounted. Then take that number and subtract 9.99 from it which gives you 8.4915 (or $8.49 rounded)

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?​

Answers

Answer:   y = (-1/2)x + 2

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
