(13÷6)×8+6

first you need to divide the one in the parenthesis, so the answer will be

(13÷6)=2.16 then,

2.17×8+6

at that point you need to do the multiplacation first, 2.17×8.

2.17×8 = 17.36 then,

17.36 + 6 now you gonna add this numbers

so the answer is 23.36.

for the other question, the same thing do the one in the parenthesis first then the multiplication then the addition.

PEMDAS - Parenthesis, Exponent, Multiplication, Division, Addition, Subtraction

just follow this then you will got your answer.

Find the maximum volume of a cylindrical soda can such that the sum of its height and its circumference is 120 cm.

Klio2033 [76]

The volume of such a can with base radius $r$ and height $h$ would be

$V(r,h)=\pi r^2h$

We desire the base's circumference and the can's height to add to 120, i.e.

$2\pi r+h=120\implies h=120-2\pi r$

Substituting this into $V(r,h)$ allows us to reduce the volume to a function of a single variable $r$ :

$V(r,120-2\pi r)=V(r)=\pi r^2(120-2\pi r)=120\pi r^2-2\pi^2r^3$

Taking the derivative with respect to $r$ yields

$V'(r)=240\pi r-6\pi^2r^2$

Set this equal to 0 and find any critical points:

$240\pi r-6\pi^2r^2=0\implies 6\pi r(40-\pi r)=0\implies r=0\text{ or }r=\dfrac{40}\pi$

This suggests the can will have maximum volume when its radius is $\dfrac{40}\pi\approx12.7$ cm, which would give a volume of about 20,371 sq. cm.

HELP ASAP PLEASE!!!!!!!

75.25x + 3604 = 300.50x
300.50x - 75.25x = 3604
225.25x = 3604
x = 16
Both companies charged the same at 16 tons
first answer 16 tons
--------------------
300.50x = 300.50(16) = $4,808
both companies charged the same are $4,808
second answer is $4,808
