You would need 6 boats.
Step-by-step explanation:
2700 divided by 254 equals about 11, 11 divided by 2 equals 5.5 rounded up is 6.
<span>To find the total loss for this play, take the two values, find their signs (positive or negative), then sum them. In this case, the play itself resulted in a movement of -12.5 yards, and the penalty added a -5 yard movement to the result. This would lead to a total movement of (-12.5 + [-5]), or -17.5 yards.</span>
Answer:
40
Step-by-step explanation:
Let the number of 20cent coins be 'x'
Then, 10cent coins are 'x + 12'
Total amount = $5.4 = 540 cents
20(x) + 10(x + 12) = 540
20x + 10x + 120 = 540
30x = 540 - 120
30x = 420
x = 420/30
x = 14 (14 20cent coins)
x + 12 = 26 (26 10cent coins)
Total coins = 14 + 26 = 40
Answer:
64 and 34
Step-by-step explanation:
Given
a + b = 8 ( square both sides )
(a + b)² = 8² = 64
------------------------------------------------
(a + b)² = 64 ← expand left side
a² + b² + 2ab = 64 ← substitute ab = 15
a² + b² + 2(15) = 64
a² + b² + 30 = 64 ( subtract 30 from both sides )
a² + b² = 34
