Mathematics

topjm [15]3 years ago
4 0

Factors can help find a common denominator because it allows you to see what numbers are shared between your two denominators.

For instance, 4 is a factor of 12.

So, if you have one denominator of 4, and one of 12, you have an official bruh moment and you can see that to get your common denominator, all ya gotta do is multiply the fraction with a denominator of 4 by 3/3

3. Find the values of the constants in each of the following:
lina2011 [118]

9514 1404 393

Answer:

  a = 8; b = -9

Step-by-step explanation:

Filling in the given values gives you two equations.

  7 = a(2) +b

  -1 = a(1) +b

Subtracting the second equation from the first gives ...

  (7) -(-1) = (2a +b) -(a +b)

  8 = a . . . . . simplify

Using this value in the first equation gives ...

  7 = (8)(2) +b

  b = 7 -16 = -9

The constants are a = 8, b = -9.

A submarine on the surface of the ocean descended at a rate of 7 feet per second for 2 minutes. Then it ascended at a rate of 4
kotykmax [81]

Answer:

4,260 feet below sea level (-4,260 feet)

Step-by-step explanation:

The submarine starts at sea level which should be 0 for elevation. And descending 7 feet per second for 2 minutes which means it went down 840 feet ( 7x60x2). Then 4 feet per second for 3 minutes which is 720 feet (4x60x3). Lastly 9 feet per second for 5 minutes which is 2,700 feet (9x60x5). Then you add up those three totals, 840 + 720 + 2,700 = 4,260. So the elevation is -4,260 feet, or 4,260 feet below sea level
