Eighths and their multiples are common fractions which I recommend memorizing, but to actually solve this, you use the literal meaning of a fraction and divide 5 by 8. See the long-division below (it was surprisingly difficult to type, so I hope it helps!).
To round 0.625 to the nearest hundredth, we go to the second decimal place, which is 5, so we round up to 0.63.
Answer:
$34.50
$1.01
Step-by-step explanation:
For these two problems, you must find a percent of a number. Since percentages can easily be turned into decimals, this is easy to do. First, turn the percent into a decimal by moving the decimal point two to the left; so, 6.25% becomes 0.0625. Then, multiply this number by the cost, 32.47. Finally add that, 2.02, to the cost to get the final answer, $34.50. For the next question do the same. Turn the percent into a decimal and then multiply that by the cost to get the total tax, $1.01.
By definition we have:
sineA = (C.O) / (h)
cosA = (C.A) / (h)
Where,
C.O: opposite leg
C.A: adjacent leg
h: hypotenuse
Substituting values:
sinA = (48) / (50)
cosA = (14) / (50)
Answer:
sineA = (48) / (50)
cosA = (14) / (50)
Option 2
We know that the pool drains at a rate of 8 gallons per minute. We can multiply 8*11. 8*11 is 88. We can now subtract 88 from 143. This gives us 55. The swimming pool has 55 gallons of water after 11 minutes.
Answer:
I think the answer is 149.842. If I'm wrong let me know.
