Answer:

35 degrees, 60 degrees, and 55 degrees

Step-by-step explanation:

I'm not sure what you're trying to ask for the answer, but I'm assuming it's the degrees.

Think about it: A right triangle automatically has a 90 degree angle, and it already gave one of the degrees as 35 degrees. Adding those up, it equals 125 degrees. 180 (sum of degrees in a triangle) -125=55 degrees.

Therefore, the triangle's degrees are 35, 55, and 60 degrees.

hope this helped!~

Mama L [17]

Answer: it will take them 4 hours to be 640 kilometers apart.

Step-by-step explanation:

Let t represent the time it will take for both trains to be 640 kilometers apart. It means that the total distance that both trains will covered in t hours is 640 kilometers.

Distance = speed × time

A train leaves Little Rock Arkansas and travels north at 75 kilometers per hour. Distance covered after t hours would be 75 × t = 75t

Another train leaves at the same time and travels south at 85 kilometers per hour. Distance covered after t hours would be 85 × t = 85t

Since the total distance covered is 640 kilometers, then

75t + 85t = 640

160t = 649

t = 640/160

t = 4 hours

Please help thank you!​

Answer:

(d) WEAK NEGATIVE ASSOCIATION.

Step-by-step explanation:

Pearson correlation (r) is defined as a factor which measures the linear dependence between two variables (x and y). It's also known as a parametric correlation.

Here, r = -0.19

Now, as r is NEGATIVE.

⇒ As the value of x increases , value of y decreases.

⇒There is a  NEGATIVE ASSOCIATION.

Now as the value of r is between 0 and ( -1). So the factor of variation is very small.

Hence, it is WEAK NEGATIVE ASSOCIATION.
