Answer:
Secretariat's average speed in the Kentucky Derby of 1973 was of 47.05 miles per hour.
Step-by-step explanation:
Secretariat set the current record of 1 minute 59.40 seconds for the Kentucky Derby, running 10 furlongs, which are 1.25 miles.
To determine the speed at which the horse ran, we must first isolate the time in which he ran, to determine the fraction of time in which he traveled the 1.25 mile.
An hour has 60 minutes. To determine the speed, whe have to divide 60 by the minutes the horse ran, and then multiply it by the number of miles he ran: 60 / 1.5940 = 37,64 x 1.25 = 47,05.
The horse ran at 47.05 miles per hour.
Answer:
The smallest whole number length is 12
Step-by-step explanation:
The sum of any two sides of any triangle must be greater than the length of the third side.
In this case, the two smallest sides of the triangle must be greater than the third side to satisfy the statement above.
Let "x" = the length of the third side.
Our two smaller sides are "x" and "4", and their sum must be greater than 15.
x + 4 > 15
x > 15 - 4
x > 11
First we subtract 100 - 35 to get 65. (Because 35% is out of 100%)
Since we already know there are 117 students, we can automatically assume 65%= 117
<span>117 is 65% of what?
We use this formula to find out: y</span><span>/p% = x
</span>Plug in the numbers so it's now 117/65%= x
Or to make it easier, 65% is also 0.65 (you can find by dividing 65/100)
So now we have 117/0.65= x
Work that through to get x= 180
Hope that helps!
