Answer:
D 75 inches, 55 inches, 45 inches
Step-by-step explanation:
The sum of the two shortest sides must exceed the length of the longest side. This is only the case for choice D.
A. 45+55 < 110
B. 45+45 = 90 . . . . needs to be greater, not equal
C. 35+45 < 100
D. 45+55 > 75 . . . . will form an obtuse triangle
Answer:
1.25 gal
Step-by-step explanation:
5/4 = 1.25
So if Jade makes $306.25 a week and for every hour she works, she makes $8.75, then all you have to do is divide 306.25 by 8.75.
306.25/8.75 = 35 hours should be your answer
Let me know if that doesn't make sense or you still don't understand it :)
Answer:
The rate of the current is 2 miles per hour.
Step-by-step explanation:
Let us assume that the rate of the river is v miles per hour.
The speed of the boat is 12 miles per hour.
Let us assume also that the boat can go 21 miles in t hours in the downstream and 15 miles upstream at the same time i.e. t hours.
So, from the condition given we can write that
......... (1), and
......... (2)
Now, adding those two equations we get
⇒
hours
Now, from equation (1), we get,
⇒ v = 2 miles per hour
Therefore, the rate of the current is 2 miles per hour. (Answer)
