Alex runs 21 hours a week.
Since, a week has 7 days, he runs, 21 hours in 7 days.
Now,
In 7 days, Alex runs 21 hours
In 1 day, Alex runs 21 / 7 hours
                            = 3 hours
In 3 days, Alex runs 3 * 3 hours
                           = 9 hours.
 
So, If he is unable to run for 3 days, he loses 9 hours of his training time.

Simora [160]

Answer:

7x +5

Step-by-step explanation:

Mason works h hours each day during the 5-day workweek. He also works 5 hours on the weekend. Write an algebraic expression for the number of hours Mason works each week.

"h hours each day in the week"

There are 7 days, so 7 × x.

"5 hours on the weekend"

5

So, this can be written as 7x + 5.

Using the Division algorithm to find q and r such that 3662 = q·16+r , where 0 ≤ r &lt; 16 . What if we take c = −3662 instead o
bagirrra123 [75]

Answer:

a) If c=3662 then q=228 and r=14.

b) If c=-3662, then q=-229 and r=2

Step-by-step explanation:

a) Observe that 229*16=3664, since r must be in the interval [0,16), then 229 doesn't work, but 228*16=3648 and 3662-3648=14.

Then 3662=228*16+14.

b) Observe that -228*16=-3648 and -3648-14=-3662, but r= must be positive. Then -228 doesn't work.

But observe that -229*16=-3664 and -3664+2=-3662. So -3662=-229*16+2

A sum of money is divided in ratio 3:5:9 . Calculate the smallest share given that the largest share is $558
MA_775_DIABLO [31]
First work out the 'multiplier'

3 + 5 + 9 = 17 so Multiplier = 1/17

$558 is the largest share  and that equals  9 * 1/17  of x  where x is the total amount of money

9x / 17 = 558

x = (558 * 17) / 9  =   $1054

So the smallest share  = 3 /17  *  1054 =  $186  Answer
