Answer:

7/12

Step-by-step explanation:

m=rise/run

The required slope of the roof is given as 7/12, as per the given conditions.

Given that,
A roof is to set one end of a 12-inch level on the roof surface and hold it level. Then take a tape measure or ruler and measure from the other end of the level down to the roof surface.

The slope is a tangent angle made by line with horizontal. i.e. m = tanx where x in degrees.

here,
Vertical reading of rising measure by a 12-inch level = 7
horizontal reading(run measure) = 12

The slope of the roof is given as,
m = rise/ run
m = 7 / 12

Thus, the required slope of the roof is given as 7/12, as per the given conditions.

Answer:

42

Step-by-step explanation:

To find the amount of water in a 63-kg person you must first find the unit rate in an 84-kg person.

84 ÷ 56 = 1.5

1.5 is how much human body weight there is as a unit rate over 1-kg of water.

1.5 x 56 = 84, so this shows we are correct.

84 ÷ 1.5 = 56, so that goes even further to prove you are correct.

Now, what's the amount of water in a 63-kg person?

1.5 is the unit rate we found out was used, so it should still be proportional.

63 ÷ 1.5 = 42.

Indeed, it is proportional. You are correct.

The answer is 42.

There is 42 kg of water in a 63 kg person.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x = 4 is an equation.

We have,

The number of kilograms of water in a human body varies directly with the mass of the body.

This means,

W ∝ M

Where W is the kg of water and M is the mass of the body.

Now,

W = KM

W = 56 kg

M = 84 kg

So,

56 = 84K

K = 56/84

Now,

For M = 63,

W = KM

W = 56/84 x 63

W = 42

Thus,

There is 42 kg of water.

If any individual factor on the left side of the equation is equal to  

0.

Answer:

x=4

Step-by-step explanation:

If you do 4-4 in the first one you get 0. Then the problem would look like this.

(0)(-5x+1)=0

It wouldn't matter what the next one looks like because you would multiply it by 0 which would give you 0.

Answer:

1.66666666667

Step-by-step explanation:

Answer:

y = 5x.

Step-by-step explanation:

Read the table from top to bottom.  You'll see that each time x increases by 1, y increases by 5.  We know immediately that the slope of this line is m = rise/run = 5/1 = 5.

Using the first point (2, 10), we see that y = 10 when x = 2.  Fit this info into the slope-intercept form of the equation o a straight line:

y = mx + b becomes 10 = 5(2) + b, or b = 0, and the final equation is y = 5x.
