Two multiple choice questions, because: 3*28 is equal to 84, so if we do 8*2 we get 16, and 84+16 is 100! Hope this helped! Brainliest is always appreciated.
Answer:
3
Step-by-step explanation:
In this case, Luis has 6 quarters, and 3 dimes. 6 - 3 = 3, and it works out to the following:
6 • 0.25 = 1.50
3 • 0.10 = 0.30
1.50 + 0.30 = 1.80
2.045 , 2.43 , 25/9. Hope this helped ;)
Answer: first choice 14.142 ft
Explanation:
1) Side length of the square: x
2) Use the Pythagorean theorem to relate the side lenght with the diagonal:
diagonal² = x² + x² = 2x²
3) Clear x:
x² = diagonal² / 2
⇒x = √(diagonal² / 2) = diagonal /√2 = diagonal √2 / 2
4) subsitute diagonal = 5 ft
⇒ x = 5 ft √2 / 2 ≈ 3.536 ft
5) The perimeter of the square is 4 times the side length:
Perimeter = 4 × 3.536 ft = 14.142 ft
