Step 1: Add up all the scores.
Step 2: count the number of scores.
step 3: divide the sum of the scores by the number of scores themselves.
step 4: The answer is 26 points.
125 is the answer.
A mean of vie numbers is 25. If it is 25, the numbers must be 25. So, since there is 5 of 25, multiply 25 by 5. Then, the answer would be 125.
There is also another way to do it. Set-up your equation.
x/5=25.
Now flip it to make the equation a multiplication problem.
25×5=x
Once you solve the equation, you should get 125 is the answer.
Answer:
H= 10
Step-by-step explanation:
Hypotenuse formula if you have the other 2 sides.
Answer:
54.2 mph
Step-by-step explanation:
Since the drivers leave at the same time and travel in directions 90° from each other, their separation speed can be found using the Pythagorean theorem. Let c represent Cynthia's average speed. Then (c-10) will represent Tim's average speed. Their combined separation speed is 70 miles per hour, so we can write ...
70² = c² +(c -10)²
4900 = 2c² -20c +100 . . . . eliminate parentheses
c² -10c -2400 = 0 . . . . . . . . divide by 2; put in standard form
(c -5)² -2425 = 0 . . . . . . . . . rearrange to vertex form
c = 5 ±5√97 . . . . . . . . . . . . solve for c, simplify radical
c ≈ 54.244 ≈ 54.2 . . . . . . . use the positive solution
Cynthia's average speed was 54.2 miles per hour.
It will be 93 because it 92 but you have to round up with deimal number
