Answer:

a. 8/24 or 1/3 a day

b. 45/60 or 3/4 a hour

24 hours is 1 day

7 days is 1 week

3-4 weeks per month (depending on the month and year)

Which relationship is always true for the angles r, x, y, and z of triangle ABC?
mariarad [96]

That's the second one,


180 - x = r


Whenever two lines cross we get congruent opposite angles and supplemental adjacent angles, i.e. they add to 180 degrees.


The first one is almost right; we have r+y+z=180 and r+x=180 so x=y+z not quite what was written.

How can I show that 0 is not a natural number​
madam [21]

Answer:

The reason why 0 is not a natural number is because does not have a value which is positive or negative. Therefore, since all real numbers are positive integers, we do not assume that zero is a natural number. Although zero is called a number in its entirety.

Please help and answer all the question too
IgorC [24]
To find the volume you use the formula—> length x width x height.

For the first problem you’ll solve 5 x 3 x 2 which is 30.

For the second one you’ll do the same thing. For this one you’ll do 3 x 3 x 2 which is 18.

Write a list of 6 ordered pairs to show the height of the candle in inches (y) as a function of time in hours (x) from the first
Bumek [7]

A function assigns the values. The list of 6 ordered pairs to show the height of the candle inches are (1,8.5), (1,8), (1,7.5), (1,7), (1,6.5), and (1,6).

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

The rate at which the candle burns down is 0.5 inches per hour. Now, if we substitute the value of the point (0,9) in the function of a line, and the rate as well, we will get,

y = mx +c

9 = -0.5(0) + c

c = 9

Now, the equation that can represent the height of the candle at any hour after it is lit will be,

y= -0.5x+9

substitute the value of x as 1, 2, 3, 4, 5, and 6 to get the value of y and form ordered pairs.

  • y=-0.5(1)+9 = 8.5 inches  ⇒ (1,8.5)
  • y=-0.5(2)+9 = 8 inches  ⇒ (1,8)
  • y=-0.5(3)+9 = 7.5 inches  ⇒ (1,7.5)
  • y=-0.5(4)+9 = 7 inches  ⇒ (1,7)
  • y=-0.5(5)+9 = 6.5 inches  ⇒ (1,6.5)
  • y=-0.5(6)+9 = 6 inches  ⇒ (1,6)

Hence, the list of 6 ordered pairs to show the height of the candle inches are (1,8.5), (1,8), (1,7.5), (1,7), (1,6.5), and (1,6).
