Answer:

A) 420 seconds = 7 minutes

B) 8 times

Step-by-step explanation:

A) After how many second would all three things happen together again?

Solution:

His clock ticked every 5 seconds , a tap was dripping every 7 seconds and     his pet dog snored every 12 seconds. It all happens simultaneously = 5*7*12=420 seconds

B) How many times would all three things happen together again between    midnight and one o'clock

Since all these events happen together after every 420 sec = 7 mins and there are 60 mins between midnight and 1 o'çlock , thus 60/7 = 8 times ....

Subtract to get your answer.
So, 3 1/6- 1 4/6
Make improper fractions so easier to subtract
19/6-10/6=9/6= 1 3/6
So your answer is A.
(It couldn’t be D because that’s more than you even started with.)

Varvara68 [4.7K]

Answer:

See explanation

Step-by-step explanation:

From the graph,

  • After 1 hour passed, 2 inches of show fell
  • After 5 hours passed, 10 inches of snow fell
  • And so on

This means, that points (1,2), (5,10) lie on the graph. This graph passes through the origin, so its equation is

y=kx,

where k is the slope

Find k:

2=k\cdot 1\\ \\k=2,

so the equation is y=2x and the slope is k = 2.

The slope means how many inches of snow fell in 1 hour.

In 1 hour, 2 inches of snow fell.
