The sum of two numbers is 72. The difference of the two numbers is 40. What are the two numbers.

Oxana [17]

Step-by-step explanation:

x + y = 72

x - y = 40

x = y + 40

so, the first equation is then

y + 40 + y = 72

2y + 40 = 72

2y = 32

y = 16

x = y + 40 = 16 + 40 = 56

the weight of a cylindrical can varies jointly with the height of the can and the square of the cans radius. A 4-inch high can w

Bess [88]

With the information given we have:
$W=k.h.r^2$
Where W is the weight, k is the proportionality constant and r is the radius of the can's radus. Remember that the weight varies jointly so this key word means that you need to multiply the mentiones parameters by a proportionality constant k.
We simply need to reorganize the expression and isolate k for the frst answer:
$k=\frac{W}{h.r^2}$
Replacing by all the appropiate values we get:
$k=\frac{16}{(1.5)^2.4}\approx1.78$
For the second part knowing k we have:
$W=\frac{16\times 4.5\times 2^2}{(1.5)^2\times 4}=32 ounces$
