The table shows the amount of red paint that can be added to different amounts of white paint while making a custom paint color:

KIM [24]

you are looking for a unit rate (for 1 quart of red, how much white is used).

notice all red amounts are less than white, so b and c make no sense.

I look at the 4:20 and think, half of the paint would be 2:10, half of that is 1:5

(you could also start with 4:20 and divide each by 4 to get this answer)

Mr Patel is planning to drive 325 miles. He will stop one hour for lunch and take a 15 min rest break.

Option D

The trip lasts for $6\frac{1}{4}\ hours$

Solution:

Mr Patel is planning to drive 325 miles

Average speed is 65 mph

He will stop one hour for lunch and take a 15 min rest break

Let us first find the time taken

$Time = \frac{distance}{speed}$

$Time = \frac{325}{65}\\\\Time = 5$

Thus he covers 325 miles in 5 hours

Also, given that, he will stop one hour for lunch and take a 15 min rest break

Therefore, total time taken for trip is:

Total time = 5 hours + 1 hour + 15 minutes

Total time = 6 hours 15 minutes

We know that,

1 hour = 60 minutes

Therefore,

$6\ hours\ 15\ minutes\ = 6 + \frac{15}{60}\ hours = 6 + \frac{1}{4} = 6\frac{1}{4}\ hours$

Thus the trip lasts for $6\frac{1}{4}\ hours$

4 more than one third of a number n is 6. An equation is? The solution is n =?

harkovskaia [24]

Answer:

$\frac{1}{3}$ n + 4 = 6

Step-by-step explanation:

Given problem:

4 more than one third of a number n is 6

Unknown:

The equation = ?

Solution of the number = ?

Solution:

let the number = n

So, 4 more than one third of a number;

One third of n = $\frac{1}{3}$ n

4 more;

$\frac{1}{3}$ n + 4

is 6;

$\frac{1}{3}$ n + 4 = 6 (equation of the expression)

Let us now solve the equation:

$\frac{1}{3}$ n + 4 = 6

$\frac{1}{3}$ n = 6 - 4

$\frac{1}{3}$ n = 2

n = 6
