\frac12 in -\frac38 ft \\
8\frac48 in - x\ ft\\
\\
\frac12x=\frac38 \cdot 8\frac49\\
\frac12x=\frac38 \cdot \frac{76}9\\
\frac12x=\frac{76}{24}\ /\cdot 2\\
x=\frac{76}{12}=6\frac13 ft\\\\
Answer:Actual\ lenght\ is\ 6\frac13ft.

How much will it cost to pour a circular slab 18 ft in diameter by 3 in. For a patio if the concrete costs $40.00 per cubic yard
sasho [114]
A circular concrete slab is a cylinder. Vol = pi%2Ar%5E2%2Ah
in this cylinder:
r = 18%2F2 = 9 ft
h = 3%2F12 = .25 ft
:


Find the volume in cu/ft:
V = pi%2A9%5E2%2A.25
V = 63.61725 cu/ft
:
Change to cubic yds; (1 cu/yd = 27 cu/ft) and multiply by $40:
Cost = 63.61725%2F27 * 40
Cost = $94.25


In practical terms , they may require you to buy 3 cu/yds , which is $120

Craig is practicing his baseball pitching he kept track of the speed of each of his throws yesterday,and made the histogram
Morgarella [4.7K]

Using it's concept, there is a 0.125 = 12.5% probability that Craig will pitch it between 70 and 75 mph.

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

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

From the histogram, the number of pitches is given by:

1 + 5 + 3 + 4 + 1 + 2 = 16.

Of those, 2 were between 70 and 75 mph, hence the probability is given by:

p = 2/16 = 1/8 = 0.125.

There is a 0.125 = 12.5% probability that Craig will pitch it between 70 and 75 mph.
