Hello there,

In order to solve this you are going to add 12 and 4/5 yards three times.

First we change 12 and 4/5 into an improper number:

  • 64/5 is the mixed number for 12 and 4/5  

Now we take 64/5 and add it three times or simply multiply by 3:

  • 192/5 is what you get when you add it three times

Now we change 192/5 into a mixed number:

  • 38 and 2/5

The quarterback threw in all 38 and 2/5 yards altogether.

Hope I helped,

Amna

Answer:

38.4 or 38 2/5

Step-by-step explanation:

He threw 12 4/5 yards for each of his three passes, so you would need to multiply 12 4/5 by 3.

12 4/5 x 3 = 38.4

You can also simplify the decimal into a fraction.

38.4 = 38 4/10 = 38 2/5.

Which of these numbers is a prime number: 1, 11, 21, 51?
statuscvo [17]

Answer:

11 and 51

Step-by-step explanation:

1 technically isn't a prime since a prime can only be divided by two things (itself and 1) and 1 can only be divided by 1.

21 can be divided by 1, 3, 7, and 21 so it is not prime.

Hope this helps!

9mph in still water it takes 5hrs longer to travel 74 miles upstream than downstream find the rate of current and round to neare
prohojiy [21]

Answer:

The rate of current is 2.5 mph.

Step-by-step explanation:

The speed in the water when current is absent is 9 mph.

If the speed of the current is v mph then the upstream speed is (9 - v) mph and the downstream speed is (9 + v) mph.

Now, it takes 5 hours longer to travel 74 miles upstream than down stream, then we can write the equation as  

\frac{74}{9 - v} - \frac{74}{9 + v} = 5

⇒ \frac{2v}{81 - v^{2} } = \frac{5}{74}

⇒ 148v = 405 - 5v²

⇒ 5v² + 148v - 405 = 0

Applying Sridhar Acharya's formula we can write  

v = \frac{-148 + \sqrt{148^{2} - 4(5)(-405) }  }{2(5)} (Neglecting the negative root)

⇒ v = \frac{- 148 + 173.2166}{10} = 2.5 mph (Rounded to the nearest 10th) (Answer)
