Well if we multiply 3.48 times two which would make 4 toothbrushes it would be 6.96. So this means if we wanted a better deal on more toothbrushes. The answer would be the package of 4

3.48x2= 6.96. Therefore if you bought the pack of 4 toothbrushes it would be a better deal bc you can get the same amount of toothbrushes for less since the 4 pack is 6.60 =)

15 1/4 acres of land are to be divided into lots of at least 2/3 acres each What is the maximum number of lots that can be creat
Sholpan [36]
Well, if you want the maximum number of splits, then you want to make
each individual split as small as possible. 
That's 2/3 acre.  How many will that give you ?

                  (15 and 1/4) divided by (2/3)

             =      (15.25)  /  (0.666...)  =  22.875 pieces .

The maximum number of 2/3-acre lots you can sell is 22 lots.

Then you have 58.3% of an acre of land left over that you can't sell
because it's less than 2/3 acre.  Sadly, that 58.3% of an acre is just
about the size of the lot that I've been living n for almost 30 years. 
You really know how to rub it in, dontcha !

Find the compound interest on 30,000 for 2years at 7 percent per annum​
hjlf

Answer:

34347

Step-by-step explanation:

Use the formula s=p(1+r/k)^kt

p=30000

r=7% (interest)

k=1 (because of per annum)

t= 2 (years)

Hence: 30000(1+0.07/1)^1(2) = 34347

N is the sum of three consecutive primes and is also the product of two 2-digit primes, what is the least possible value of N
Nookie1986 [14]

Hello from MrBillDoesMath!

Answer:   N = 143

Discussion:

This one took some trial and error! At first I listed all 2 digit primes, looked at the list, but didn't know how to proceed. So, I took the smallest 2 digit primes numbers:  11 and 13 and wondered if their product, 13*11 = 143, could be represented as the sum of  3 consecutive primes.   I went back to my list of primes,  added groups of three consecutive numbers that seemed to be in the right range to give the desired sum, and stumbled on  43, 47, and 53!

43 + 47 + 53 =  143 !


Therefore N = 143. It's the sum of 43, 47, and 53 as well as the product of 11 and 13.


Thank you,

MrB

Find the value of Q in the following system so that the solution to the system
lisabon 2012 [21]

Answer:

<h2>Q = -6</h2>

Step-by-step explanation:

If the solution of the system of equations is {(x, y): x - y = 4} - infinitely many solutions, then this system is consistent and dependent.

x - 3y = 4            <em>multiply both sides by 2</em>

2x - 6y = 8

Therefore Q = -6
