Answer:

9\frac{3}{2} smallest

27\frac{1}{3}

125\frac{2}{3} largest

Step-by-step explanation:

First change the mixed numbers into an improper fractions.

9\frac{3}{2} = \frac{21}{2}  9 x 2 = 18 + 3 = 21

27\frac{1}{3} = \frac{82}{3} 27 x 3 = 81 + 1 = 82

125\frac{2}{3} = \frac{377}{3} 125 x 3 = 375 + 2 = 377

Find the least common denominator.

2 and 3 have 6

\frac{21}{2} = \frac{63}{6} smallest

\frac{82}{3} = \frac{164}{6} medium

\frac{377}{3} = \frac{754}{6} largest

A cheetah ran 275 feet in 3.23 seconds. How fast did the cheetah run in miles per hour? Round your answer to the nearest whole m
yawa3891 [41]
First we convert feet into meters, since 1 feet is 0.3048 m: 275 feet * 0.3048 = 83.82m.

Then we do: 83.82m / 3.23s =  <span>25.9504644 m/s.

Then we convert that into miles per hour by </span>2.23694, so we do:

25.9504644 * 2.23694 = <span>58.0496318.

Then we round it to 58 mph.

So the answer is: The cheetah was running at 58 mph.

Hope this helped! c:</span>

At the market, 7 apples cost $4.55. How much do 9 apples cost?
Dvinal [7]
7 apples = 4.55
To find the single cost of an apple, divide 4.55 by 7
4.55/7 = 0.65 per apple
Let's check to see if this is right.
0.65 x 7 = 4.55 = correct
0.65 x 9 = $5.85 for 9 apples

Line AC is tangent to circle O at point C<br> What is the measure of OAC?
Nuetrik [128]
AC is a tangent so by definition, it touches the circle at exactly one point (point C) and forms a right angle at the tangency point. So angle ACO is 90 degrees

The remaining angle OAC must be 45 degrees because we need to have all three angles add to 180
45+45+90 = 90+90 = 180

Alternatively you can solve algebraically like so
(angle OAC) + (angle OCA) + (angle COA) = 180
(angle OAC) + (90 degrees) + (45 degrees) = 180
(angle OAC) + 90+45 = 180
(angle OAC) + 135 = 180
(angle OAC) + 135 - 135 = 180 - 135
angle OAC = 45 degrees

Side Note: Triangle OCA is an isosceles right triangle. It is of the template 45-45-90.
