(A) 12:50 pm
Step-by-step explanation:
In the above question, we are asked about that COMMON TIME in which both the bells rings together.
So, in order to find that common time, we will figure out the L.C.M. of 20 and 35.
LCM (20, 35) = 140 minutes, i.e. 2hours and 20 minutes
Now, time after a duration of 2hr and 20 min from 10:30 am =
10:30 + 2:20 = 12:50 pm

C. 0
D. 44
Answers
Answer:
A. 8
Step-by-step explanation:
Use PEMDAS
E for exponents (4^2)/(2^1)
4^2 = 4 * 4 = 16
2^1 = 2
D for division
16/2 = 8
So the answer is A
Hi!
Let's solve it together.
4^2 is just 4x4,
4 x 4 = 16
Next, 2^1.
2^1 is just 2, so the answer is 2.
Now, we divide 16 and 2.
16 ÷ 2 = 8
So, the answer is A.Hope this helps!~~~PicklePoppers~~~A family gathered 20 small seashells from the beach bringing the total number of small seashells in their collection to 41.

[tex]a^{2}+b^{2}=c^{2}[/tex]
Subtract b squared from both sides.
[tex]a^{2}= -b^{2}+c^{2}[/tex]

She collects data on the number of turkey sandwiches sold per day for a week. Explain to her how to find the mean, median, mode, and range of the number of turkey sandwiches sold. How that would be helpful when she orders new turkey sandwich makings? Which measure do you think would be the most helpful for her and why?
Answers
Answer:
In order to find the mean of the sandwich shop you would add all of them up so 73+88+85+88+99+134+129 = 696. Then you divide it by how many days there are which there are 7 days so 696÷7=99.43. To find the median order the number least to greatest, then u count how many numbers are in the set. Count inwards and the median would be 88. The mode is the set of number that is in the problem the most, so in this case the mode would be 88. In order to find the range you subtract the highest number from the lowest number, so 134-73. The range would be 61. The measure that would be most helpful is the median, because it is not affected by the outliers!!

To rent a certain meeting room, a college charges a reservation fee of $19 and an additional fee of $4 per hour. The chemistry club wants to spend at most $47 on renting the room. What are the possible numbers of hours the chemistry club could rent the meeting room?
Answers
Answer:
The possible number of hours the chemistry club can rent the meeting room is 7 hours.
Step-by-step explanation:
h=hours
19+4h=47
Subtract 19 from both sides of the equation.
4h=28
Divide 4 from both sides of the equation.
h=7
The possible number of hours the chemistry club can rent the meeting room is 7 hours.
Hope this helps :)
Answer:
7 hours
Step-by-step explanation:
There is $47 total dollars. The reservation fee is $19 dollars. Subtract the two:
47-19= 28 dollars
Now the per hour fee is 4 dollars an hour. And you have 28 hours. So divide the two to get maximum hours:
28/4=7 hours

Rewrite 1/5 barrel 1/2 hour as a unit rate
Answers
Hope this helps! ☺️
Unit rate of (1 /5 barrel) / (1/2hour) is equals to (2/5) barrels /hour.
What is unit rate?
"Unit rate is defined as the representation of the ratio of the two different units with value of the denominator equals to 1."
According to the question,
Given,
[tex]\frac{\frac{1}{5} barrel}{\frac{1}{2} hour}[/tex]
⇒ (1 / 2) hour = ( 1/ 5) barrel
⇒ 1 hour = ( 2 / 5) barrel
⇒( 2 / 5) barrel per 1 hour
Therefore,
Unit rate of given value is rewritten as
[tex]\frac{2}{5}[/tex] barrel / hour
Hence, Option(B) is the correct answer.
