Dan and his family are traveling to North Carolina. On Monday, they drove 3/8 of the trip and on Tuesday they drove 4/8 of the trip. How much of the trip did they drive so far?

They drove 87.5% of the trip so far.

Step-by-step explanation:

The total of the trip is 100%.

On Monday, they drove 3/8 of the trip

So on Monday, 3/8 = 0.375.

On Tuesday they drove 4/8 of the trip

So on Tuesday, 4/8 = 0.5

How much of the trip did they drive so far?

0.375 + 0.5 = 0.875

They drove 87.5% of the trip so far.

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
