Answer:
6. 19 candles
7. 6 pills
Step-by-step explanation:
6. If a particular candle burns for 2 3/4 hours (=2.75) and you want to use similar candles to burn one at a time over 10 days for 5 hours each day, find the total number of hours: 10 x 5 = 50 hours. Then, divide by the amount of time it takes for one candle to burn: 10÷2.75 = 18.18. Since the answer is a decimal, you will need to round to the next whole number = 19 candles.
7. Given the rules that no more than three pills may be taken in a four-hour period and each pill must be taken 1 1/2 hours (=1.5) apart, you can take the total number of hours (10) and divide by the time between each pill (1.5):
10 ÷ 1.5 = 6.7
Since you won't take part of a pill, the most you can take is 6 and because the intervals are 1.5 hours, 1.5 + 1.5 + 1.5 = 4.5, you will not have taken more than 3 in any four hour period.
Answer:
∠EFH
Step-by-step explanation:
If AB and CD are parallel lines and EF is a transversal line, then angles formed on the same side of the transversal line and are exterior to the parallel lines are same side exterior angles.
Same side exterior angles theorem states that same-side exterior angles are supplementary.
From the image attached below:
∠ABC and ∠EFH are same side exterior angles, therefore:
∠ABC + ∠EFH = 180°
D
An acute angle is less than 90 degrees
Answer:
Exact: 10.08
To 1 decimal place: 10.1
Step-by-step explanation:
Just ask.
Hope this helps.
Dividing by a fraction is the same as multiplying by its reciprocal
example
the reciprocal of 3/4 is 4/3
hence for your problem
