Answer:

Step-by-step explanation:

When you divide each of the prices by the amount of candy bars, B is the lowest. The price for 1 candy bar with A's price is 1.75. The price for 1 candy bar for B's is 1.71. The price for 1 candy bar with C's is 1.73 and the price of 1 candy bar for D's is 1.74. Again, B has the lowest price for 1 candy bar so the correct answer is B.

Answer:

Step-by-step explanation:

Let's find the unit price of each choice. Unit price is essentially how much one object is worth.

A) We know that there is $19.25 for 11 candy bars, so to find the unit price, simply divide 19.25 by 11:

19.25/11 = $1.75 / candy bar

B) We know that there is $15.39 for 9 candy bars, so to find the unit price, simply divide 15.39 by 9:

15.39/9 = $1.71 / candy bar

C) We know that there is $17.30 for 10 candy bars, so to find the unit price, simply divide 17.30 by 10:

17.30/10 = $1.73 / candy bar

D) We know that there is $22.62 for 13 candy bars, so to find the unit price, simply divide 22.62 by 13:

22.62/13 = $1.74 / candy bar

Comparing all these unit prices, we see that the deal from part B is the lowest, so that's the best one.

Hope this helps!

What is 6 divided by 812

maksim [4K]

6 divided by 812 is very difficult to do without using a calculator - I would suggest the bus shelter method, as I've shown in the photo attached, but it is still quite difficult to use that method without a calculator.

<em>If</em>, however, you mean 812 divided by 6, that is a lot easier to calculate using the bus shelter method - so, just in case, I've attached the method for that too.

6 divided by 812 = 0.007389...

Carissa and Louann both have savings accounts. Carissa has $250 in her account and deposits $80 per month. Louann has $1230 in h

zlopas [31]

Carissa value after x months=current+amount deposited
louan value after x months=current-amount taken out

carissa depositied=amount per month times x months=80x
louan take out=amount per month tiems x months=60x

when wil amount be equal
se equal

cariss=lousa
250+80x=1230-60x
add 60x both sides
250+140x=1230
minus 250 both sides
140x=980
divide both sides by 140
x=7

find how much that is
250+80(7)=250+560=810

Setting:

nata0808 [166]

A. Mr. Kent interviewed the 54 students as they are going to leave the school, it is not considered to be a random sample. It is because a random sample is when a set is taken from a population. Mr. Kent interviewed the 54 who are going to leave, meaning, he didn't take a set out of that 54, he took all of them. So it is not a random sample.

b. The question that Mr. Kent asked is considered to be a leading question, so it does not seem biased.

c. If there are 54 respondents.
51 = yes, the rest is no.
= 54 - 51 = 3
= 3 is now divided to 54 = 3/54
= giving an answer of 0.0555
= 0.0555 x 100
= 5.6%
= The percent of responses that says 'no' is 5.6%

A club swimming pool is 21 ft wide and 33 ft long. the club members want an exposed aggregate border in a strip of uniform width

vovangra [49]

First compute the perimeter of the pool:
(21+33)*2=108 foot.
Since the material cover 232 ft^2, then it is sufficient to divide the above number over the length of the border like this:
232/108=2.1

The trip can be 2.1 ft in wide.
