Answer:

  • k = 45 . . . miles per hour
  • k = 1/45 . . . hours per mile

Step-by-step explanation:

One way we can relate distance and time is ...

  time = k × distance

Then the value of k (the constant of proportionality) is ...

  k = time/distance = 4 hours/(180 miles)

  k = (1/45) hours/mile

__

Another way we can relate the variables is ...

  distance = k × time

Then the value of k (the constant of proportionality) is ...

  k = distance/time = (180 miles)/(4 hours)

  k = 45 miles/hour

Mikhael and Hema are planning the annual school fundraiser. They
babunello [35]

Percent of earnings that go to school = 80%

Percent of earnings that was spent on the fundraiser cost = 20%

Last year earnings were= $4000

80% of 4000 went to school which is =

\frac{80}{100}\times4000=3200

20% of 4000 =\frac{20}{100}\times4000=800 went to costs.

a:

As given, this year, they want  $4,000 to go directly to the school.

So let the earnings this year be represented by = x

As, 80% of the earnings go to school, so 80% of x = 4000

\frac{80}{100}*x=4000

80x=400000

x=5000

Hence, this year their earnings should be $5000 so that 80% of it which is $4000 will go to school. And 20% which is $1000 will go to costs.

Or we can say last year they earned $4000, so this year they need to earn $1000 more.

b:

The total amount they need to earn this year is $5000.
