Answer:
Step-by-step explanation:
d = 24 x h
since d is the distance in order to get that we need to multiply the speed times time and get the answer
-2y>12x-42
y<21-6x
so a is true
Answer:
50
Step-by-step explanation:
Use pythagoreom theorem to determine the length of the hypotenuse:
a² + b² = c²
- assign side a to 30 and side b to 40
30² + 40² = c²
90 + 160 = c²
250 = c²
Now square root both sides to isolate side c:
√250 = √c²
50 = c
side c = 50
Answer: THIRD OPTION.
Step-by-step explanation:
For this exercise you need to use the formula for calculate the distance between two points. This is:

Given the following points:
and 
You can identify that:

Knowing these values, the next step is to substitute them into the equation for calculate the distance between two points and then evaluate.
Therefore, the distance between
and
is:

We simply need to find a common denominator. The common denominator between the two (LCM/Least common multiple for denominator) is 24.
Now, we multiply the numerators also. We have our new numbers: 2 8/24 for October, 12/24 for November, and 3 9/24 for December. Now, we have to add them together. 2 8/24 + 12/24 = 2 20/24
Now, add the December value to the combined October/November values.
2 20/24 + 3 9/24 = 5 29/24
Now, we need to simplify the fraction.
6 9/24
Answer: 6 3/8 inches of rain occured in the three months.
