Since 40%=40/100=4/10, we can divide 11 by 10 and multiply that by 4 to get the weight gained, which is 1.1*4=4.4. The weight gained paired with the starting weight = 10+4.4=14.4
Answer:
12 5/8 tons were delivered by the third truck
Step-by-step explanation:
25 = 6 4/8 + 5 7/8 + x
25 = 12 3/8 + x
- 12 3/8
12 5/8 = x
<u>Answer:</u>
x = ±5
<u>Step-by-step explanation:</u>
We are given the following polynomial function and we are to find all of its real roots:
Let 
so we can now write it as:
Factorizing it to get:
Substitute back to get:
The quadratic factor has only complex roots. Therefore, the real roots are x = ±5.
<span>Given:
family travelled 25 miles in 30 minutes or 50 miles /hr
current time 3.00 pm.
total distance=225 miles.
solution:
speed = distance * time
time = distance/spedd
= 225/50
time = 4.5 hours.
reaching time= 3 hours +4 hour 30 minutes= 7.30 pm</span>
