1) The MST will have 3 connections to Mal, more than any other node.

2) The sum of weights is 250 +3*300 +500 = 1650.
.. (You can rule out 1560 as a choice because no weight ends in 10 or 60. This is simply test-taking savvy, not math.)

How many whole cans can the company make out of each sheet of metal?

klio [65]

Answer:

Step-by-step explanation:

Total Surface Area of the Metal Sheet = $1000\:in^2$

Given a cylinder with diameter 3 Inch and height $4\frac{1}{4} in$

To determine how many whole cans can be made, the first step is to find the total surface area of each of the cylindrical can.

Total Surface Area of a cylinder = $2\pi r^2+2\pi rh$

Radius =3÷2=1.5 Inch

Height of the can = $4\frac{1}{4} in$

Total Surface Area of each can

$2\pi r^2+2\pi rh=2\pi r(r+h)\\=2*1.5*\pi(1.5+4.25)\\=3\pi *5.75\\=17.25\pi \:in^2$

Number of Cans that can be Made

To determine this, we divide the total surface area of the metal sheet by the total surface area of each can.

Number of Cans=Total surface area of the metal sheet÷Total surface area of each can.

$=1000 \div 17.25\pi\\=18.45$

Therefore, the company can make 18 whole cans from each sheet of metal.

R/16 + 6 = 7 pLEASE HELP WITHIN A HOUR OR TWO

cestrela7 [59]

Solution:

Simplify the equation and solve for r.

r/16 + 6 = 7
=> r/16 = 7 - 6
=> r/16 = 1
=> r = 16

The value of r is 16.

Check:

r/16 + 6 = 7
=> 16/16 + 6 = 7
=> 1 + 6 = 7
=> 7 = 7 (Proved correct)
