What is the smallest number greater than 100 that is :

krek1111 [17]

I'd start by listing out the multiplies of all three past 100, like this:
102, 104, 106, 108, 110, 112, 114, 116, 118, 120, 122, 124, 126, 128, 130
104, 108, 112, 116, 120, 124, 128, 132, 136
110, 120, 130, 140
Now it's just a matter of finding the number that is the same for all three of them, which is 120.

Target sells 24 bottles of water for $3, and 36 bottles of water for $4. Which is the better buy and by how much?

pishuonlain [190]

Answer:

D) 36 bottles for $4 by 1.4¢ per bottle

Step-by-step explanation:

We calculate bottle per dollar for each option.

#A

Bottles/Dollar= $\frac{24\ bottles}{\$3}=8$ bottles/dollar

#Both B and C charges the same as A and will have bottle/dollar ration of 8:1

#D

$=\frac{36}{4}\\\\=9$

Hence, D is the better buy as it gives you 9bottles per $1 spent as compared to the 8 bottles per $1 spent as in the other 3 options.

About how accurately must the tank's exterior diameter be measured to calculate the amount of paint it will take to paint the si

kondaur [170]

Answer: The error of the diameter would be 5% .

Step-by-step explanation:

Since we have given that

$S=2\pi rh$

Here, r is the radius

h is the height

So, it becomes,

$S=2\pi (\dfrac{D}{2})h\\\\S=\pi Dh\\\\S=\pi D\times 10\\\\S=10\pi D$

So, we will derivate S wrt D, we get that

$\dfrac{dS}{dD}=10\pi\\\\dS=10\pi dD$ ---------------------(1)

As we have given that

it will take to paint the side of the tank to within 5% of the true amount.

So, it becomes,

$dS=0.5\pi D$ ---------------(2)

So, from (1) and (2) , we get that

$0.5\pi D=10\pi dD\\\\\dfrac{0.5\pi}{10\pi}=\dfrac{dD}{D}\\\\0.05=\dfrac{dD}{D}=5\%$

Hence, the error of the diameter would be 5% .
