The value of y varies directly with the value of x. When y = 15, x = 3. What is the value of x when y = 60?

1 answer:

6 0

The answer is B
because at first y was equal to 15 and x equaled to 3 the quotient of 15/3 = 5.
now the y is 60 so, 60/5 = 12

assuming $219_{10}$

Then the column values for base five here are

5³ 5² $5^{1}$ $5^{0}$

We can get 1 × 5³ = 125 → 219 - 125 = 94

We can get 3 × 5² = 75 → 94 - 75 = 19

We can get 3 x $5^{1}$ → 19 - 15 = 4

and 4 = 4 × $5^{0}$

Thus $219_{10}$ = $1334_{5}$

As a check

(1 × 125 ) + (3 × 25 ) + (3 × 5 ) + 4 = 219

It will be six laps because 8 times three equal 24 and 2 laps in 8 minutes each 8 min will be two so 2 times three equal six
