Answer: 160 cans
Step-by-step explanation:
Step 1: Write out what you know and what your equation is
1/4 pound = 8 cans
5 pounds = x cans
Step 2: Find how many can you need to make 1 pound
1/4 pounds = .25 pounds
.25 x 4 = 1 pound 8 x 4 = 32
1 pound = 32 cans
Step 3: Finish Solving
1 pound = 32 cans
5 pounds = x cans
5 pounds = 32 x 5
5 pounds = 160 cans
Hope This Helps!
Answer:
ΔABC is not a right- angled triangle
Step-by-step explanation:
Given AB = 8, BC = 5
Then AC = 22 - (8 + 5) = 22 - 13 = 9 cm
Using the converse of Pythagoras' identity
If the square of the longest side equals the sum of the squares of the other 2 sides then triangle is right.
AC² = 9² = 81
AB² + BC² = 8² + 5² = 64 + 25 = 89
81 ≠ 89, hence ΔABC is not right- angled
