It took Andre and Lin 1.5 hours for them to meet.
Speed is the ratio of distance travelled to total time taken. Speed is given by:
Speed = distance/time
Let d₁ represent the distance covered by Andre at time t and d₂ represent the distance covered by Lin at time t.
Hence:
5 = d₁/t
d₁ = 5t
3 = d₂/t
d₂ = 3t
Andre and Lin are 12 miles apart, hence:
d₁ + d₂ = 12
5t + 3t = 12
8t = 12
t = 1.5 hours
It took Andre and Lin 1.5 hours for them to meet.

The answer to Part A is 13.25.
And the answer to Part B is hen you round to the nearest 10th the steps are nearly always the same:<span>Identify which place value you are rounding to. The smaller the place value, the more accurate the final result will be.Look to the next smallest place value, the digit to the right of the place value you're rounding to. For example, if you want to round to the nearest ten you'd look at the ones place.If the digit in the next smallest place value is less than five (0, 1, 2, 3, or 4), you leave the digit you want to round to as-is. Any digits after that number (including the next smallest place value you just looked at) become zeros, or drop-off if they're located after the decimal point. This is called rounding down.<span>If the next smallest place value is greater than or equal to five (5, 6, 7, 8, or 9), you increase the value of the digit you're rounding to by one (+1). Just like before, any remaining digits before the decimal point become zeros, and any that are after the decimal point are dropped. This is called rounding up.

C. 1/13 because there are 4 2’s in a deck of cards. So that’s 4/52 which is rounded to 1/13
Answer:
40.3 feet
Step-by-step explanation:
Use trigonometry.
First, set your calculator to Degrees instead of Radians. Next, draw a model like the attached image to help you better understand the question.
Now, figure out which trigonometric ratio to use. In this case, it is easiest to use sine (or cosine).
sin(38°) = x / 125
125(sin(38°)) = x
x ≈ 37.046
Finally, to find the height, simply add how high the hand is from the ground:
h = 37.046 + 3.25 = 40.296
So,
h ≈ 40.3 ft
It has 2 sides of equal length
