The answer would be the next day at two in the morning
The correct answer is 8
Because
In triangle ORB
OR=(OB^2-RB^2)^1/2
OR=(17^2-15^2)^1/2
OR=(289-225)^1/2
OR=(64)^1/2
OR=8
RB=AB/2 so I kept its value 15 and ^1/2 refers to square root
Answer:
c
Step-by-step explanation:
Answer:
4 pounds and 1/4 ounces
Step-by-step explanation:
8 and 1 half pounds = 8.5 Ibs
One half of 8.5 = 8.5/2 = 4. 25 Ibs or 4 & 1/4 or 4Ibs 4 ounces.
Because the student scored 73/100 on the first test, their current average is 73%.
To calculate the avergae with the next test score, you add both percentages the student gets together and then divide by 2.
79 = (73 + x) / 2
Multiply by 2 on both sides
158 = 73 + x
Subtract 73 on both sides
x = 85
So the student needs to get at least an 85/100 on the next test to maintain a 79 average.
