Answer:
3.73 hours
Explanation:
In 1 hour, Lisa does 1/7th of the order while Bill does 1/8th of the order in an hour. To find out how long it will take them to fill the order, we have to:
Step 1:
Add the rate of both Lisa and Bill together
1/7 + 1/8
Step 2:
Since both denominators of the fractions are different, you have to find the least common multiple of 7 and 8
7·8= 56 8·7= 56
which is 56.
Step 3:
Then, you have to multiply the numerator of 1/7 with 8 and the numerator of 1/8 with 7.
1·8= 8 1·7= 7
The fractions would now have equal denominators:
Lisa: 8/56 Bill: 7/56
Step 4:
Now, you can add them together
8/56 + 7/56
which equals to 15/56. Both Lisa and Bill together completes 15/56th of the order in 1 hour.
Step 5:
15/56 is not the final answer as it is the RATE of them working together. To find how long it will take them total to complete the order, you must divide 56 with 15.
56/15
which is 3.73 hours in decimal form (rounded).
Answer:
The Area of a circle is
Therefore the Area of Circle A is
Area of Circle B is
Circle C
Circle D
You have to divide 234 by 13
the answer is 18
Answer:
900 meters
Step-by-step explanation:
There are about 3 feet in a meter, so to find the answer you have to add up all the meters he swam and then multiply it by that.
So the equations will be: 100+200=300, 300x3=900.
Hope you get an A! <3
There are 3 vowels out of 11 letters in the word CANDLESTICK.
Probability (vowel) = 3/11
P( N or S) = 2/11 ( as there is 1 S and 1 N in the word)
P(not C) = 1 - P(picking a C) = 1 - 2/11 = 9/11 (note there are 2 C's in the word)
