There are 15 risers in a set of stairs running from the basement to the first floor. Each riser is 7 1/4" high. What is the dist
slava [35]
<h3>Answer: 108.75 inches or 9.0625 ft</h3>

This is equivalent to 9 ft + 0.75 of an inch, or 9 ft + 3/4 of an inch

==========================================================

Work Shown:

7 & 1/4 = 7.25

Each riser is 7.25 inches tall

15 of them gives a total height of 15*7.25 = 108.75 inches

Divide that by 12 to convert to feet

108.75/12 = 9.0625 feet

9.0625 ft = 9 ft + 0.0625 ft

9.0625 ft = 9 ft + (0.0625 ft)*(12 inches/1 ft)

9.0625 ft = 9 ft + 0.75 inches

9.0625 ft = 9 ft + 3/4 of an inch

Direction: Determine whether each ordered pairis a solution to the given inequality
Klio2033 [76]

Answer:

Step-by-step explanation:

1).b).  2x - 3y > 5

   For (2, 1),

   2(2) - 3(1) > 5

    1 > 5

    False.

   So the answer is NO.

c). For (6, 2),

    2(6) - 3(2) > 5

    12 - 6 > 5

    6 > 5

    True.

    Therefore, the answer is YES.

2). a). 3y + x ≤ 12

    For (3, -2),

    3(-2) + 3 ≤ 12

    -6 + 3 ≤ 12

     -3 ≤ 12

     True.

     Therefore, answer is YES.

b). For (4, 6),

    3(6) + 4 ≤ 12

     18 + 4 ≤ 12

     22 ≤ 12

     False.

     Therefore, answer is NO.

c). For (-1, -2),

    3(-2) + (-1) ≤ 12

     -6 - 1 ≤ 12

     -7 ≤ 12

     True.

     Therefore, answer is YES.

3). a). y < 3x - 15

      For (5, -3),

      -3 < 3(5) - 15

      -3 < 0

       True.

      Therefore, answer is YES.

 b). For (7, 5),

      5 < 3(7) - 5

      5 < 21 - 5

      5 < 16

      True.

      Therefore, answer is YES.

  c). For (3, -5),

       -5 < 3(3) - 5

       -5 < 9 - 5

       -5 < 4

        True.

       Therefore, answer is YES.

The sum of 6 consecutive integers is 204
dolphi86 [110]

Denote the average of the six numbers as n. This will be an even number and the six odd numbers are:

<span>n−5,n−3,n−1,n+1,n+3,n+5</span>

Then:

<span>204=<span>(n−5)</span>+<span>(n−3)</span>+<span>(n−1)</span>+<span>(n+1)</span>+<span>(n+3)</span>+<span>(n+5)</span>=6n</span>

Divide both ends by 6 and transpose to find:

<span>n=<span>2046</span>=34</span>

So the six odd numbers are:

<span>29,31,33,35,37,<span>39</span></span>

At a given time of day , the ratio of the height of an object to the length of its shadow is the same for all objects. If a 4-ft
kherson [118]

Answer:

  38.40 ft

Step-by-step explanation:

The problem statement tells you the proportion is ...

  height/shadow = (4 ft)/(2.4 ft) = (tree height)/(23.04 ft)

Multiplying by 23.04 ft, we find ...

  tree height = (23.04 ft)(4/2.4) = 38.40 ft

The height of the tree is 38.40 ft.
