Answer:
10
Step-by-step explanation:
d = √(x2 -x1)² + (y2 - y1)²
√(-6 - 0)² + [1 - (-7)]²
√(-6)² + (8)²
√(36) + (64)
√100
= 10
Answer:
84
Step-by-step explanation:
The sum of the differences of the current scores from average is ...
(84 -85) +(92 -85) +(71-85) +(94 -85) = -1 +7 -14 +9 = 1
So, to make the total of all differences from average be zero, Steve must get a score of 85 -1 = 84 on his 5th test.
Answer:
Conrad worked 11 2/3 hours this week.
Step-by-step explanation:
In order to find the total number of hours that Conrad worked this week, we need to take his total from the week before and multiply it by the increase in time from this week. Seeing the key word 'times' in the problem lets us know that the operation is multiplication. In order to make our multiplication problem easier, we can convert both mixed numbers into improper fractions. 6 2/3 is also 20/3 and 1 3/4 is also 7/4. We can then multiply 20/3 x 7/4, in which case we multiply the numerators together and the denominators together to get: (20 * 7)/ (3*4) = 140/12 = 11 2/3 hours for this week.
