Answer:
the amount received in change is $0.70
Step-by-step explanation:
The computation of the amount received in change is shown below:
= Given amount - purchased amount
= (3 × 50 + 4 × 20 + 4 × 5) - $249.30
= (150 + 80 + 20) - $249.30
= 250 - 249.30
= $0.70
Hence, the amount received in change is $0.70
Answer:

Step-by-step explanation:
Longest side of ∆ = 2a = 6.2 cm
If the shortest side is, a, and we are told that the longest side is twice the shortest side, therefore, length of shortest side is
The sum of the 3 sides = perimeter = 14.5 cm
Thus,

Plug in the values of a and b

The equation that can be used to find the side lengths is 
Convert "3/4 ton" into pounds. Use the identity 2000 lb = 1 ton.
2000 lb 1500 lb
Then [(3/4) ton] * ---------------- = ----------------
1 ton 1
Now divide 1500 lb by 4 lb 14 oz. Note that 4 lb 14 oz = 4 14/16 lb, or
4 7/8 lb, or 4.875 lb.
Then, divide 1500 lb by
4.875 lb
------------ to determine the number of bricks the truck can safely carry.
1 brick
This comes out to 1500/4.875 bricks, or approx. 307 bricks.
