Answer:
0.625lb bag of bird seeds
Step-by-step explanation:
She starts with a 3.5 lb bag,
Then she uses 3/4 of the bag, so find the remaining amount in the bag, which would be 1/4 of the original weight;
1/4 * 3.5
= 1/4 * 7/2
= 7/8
Then she removes 0.25 lbs of weight, hence take away 0.25 (the amount removed) from 7/8 (the current weight of the bag).
7/8 - 0.25
= 7/8 - 1/4
= 7/8 - 2/8
= 5/8
So she has a 5/8lb bag of bird seeds or a 0.625lb bag.
Answer:
c = 
km
Step-by-step explanation:
Here's the required formula to find the missing side of triangle by pythagoras theorem :
a = 20 km- b = 21 km
- c = ?
Substituting all the given values in the formula to find the third side of triangle :
Hence, the length of missing side of triangle is 29 km.
