The top of a 16-ounce can of a drink is three times thicker than the sides and bottom (so that the flip-top opener will work pro

perly), and the can has a volume of 473 cubic centimeters. What should the radius and height of the can be in order to use the least possible amount of metal? [Assume that the entire can is made from a single sheet of metal, with three layers being used for the top.]

What is the following product?<br> 3v2(5v6-7v3)
steposvetlana [31]

Answer:

3v^2\left(5v^6-7v^3\right)=15v^8-21v^5

Step-by-step explanation:

Given the expression

3v^2\left(5v^6-7v^3\right)

Apply the distributive law

a\left(b-c\right)=ab-ac

a=3v^2,\:b=5v^6,\:c=7v^3

=3v^2\cdot \:5v^6-3v^2\cdot \:7v^3

=3\cdot \:5v^6v^2-3\cdot \:7v^3v^2

=15v^8-21v^5

Thus, we conclude that

3v^2\left(5v^6-7v^3\right)=15v^8-21v^5

Arada [10]
The answer is <span>12^2=x^2+8^2-16x(cos(72°) </span>
<span>x^2-4.9443x=80 </span>
<span>(x-2.4721)^2=86.1115 </span>
<span>x-2.4721=±9.2796 </span>
<span>x=11.7517 </span>

<span>B=72°, b=12, c=8, a=11.8 </span>
<span>C=arcsin(8/12*sin(72°))=39.3° </span>

Mini muffins cost $3:00 per dozen Andre says I have $2:00 so I can afford 8 muffins Elena says I want to get 16 muffins so I’ll
jasenka [17]

Answer:

I agree with both.

Step-by-step explanation:

If it's $3 per dozen that would be $0.25 per muffin because

3 ÷ 12 = 0.25

And if Andre has $2 than he can only afford 8 muffins because

0.25 x 8 = 2

And if Elena wants 16 muffins

16 x 0.25 = 4

So she will have to pay $4.

Hope this makes sense and helps!
