Determine whether the graphs of y =-9x+12 and y=1/3x-12 are parallel, perpendicular, coincident
notka56 [123]

1) graphs y = -9x + 12 and y = 1/3x - 12 are not coincident.

2) The graphs are not parallel, because the angular coefficients are not equal

3) The condition of perpendicularity:

k_1\cdot k_2=-1, where k_1=-9;~~~ k_2=\frac{1}{3}


(-9)\cdot\frac{1}{3}=-3\ne -1 - not perpendicular

Donald Trump wants to build a 100 meter high tower as quickly as possible. He has unlimited resources and an unlimited budget an
Sladkaya [172]

It will take 100 weeks to build the tower.

Since Donald Trump wants to build a 100 meter high tower as quickly as possible with blocks that are 100 meters long and 100 meters wide, but only 1 meter tall, and using special lifters, putting one stack on top of another stack takes one week regardless of how high the stacks are, to determine what is the shortest amount of time (weeks) that it will take to build the tower, the following calculation must be performed:

  • Time per block x total blocks = Total time
  • 1 week x 100 = X
  • 100 weeks = X

Therefore, it will take 100 weeks to build the tower.

As a lifeguard, you can earn $5 per day plus $7.50 per hour. How many hours you must work to earn $50 in one day?
ELEN [110]

Answer:

Step-by-step explanation:

Earnings = 5 + 7.50x  You want to earn 50.00

50 = 5 + 7.50x             Set up equation  

45 = 7.50x                    Subtract 5

45/7.50 = (7.50/7.50) x Divide by 7.5

x = 6

You need to work 6 hours.

Adding mixed numbers. Can someone help me correct my answer?
Olin [163]

Answer:

27 13/60

Step-by-step explanation:

What you have tried to do is not an impossible way to do it. What you could do is set your fractions and whole numbers like this.

( 7 + 1/10) * (3 + 5/6) I don't know if you know what FOIL is, but that is the way to proceed.

  • First: (meaning the first in each factor ).   3 * 7 =                                    21
  • Outside: (meaning the two terms near outside the brackets) 7 * 5/6 = 5 5/6
  • Inside: The two terms closest to the * sign      1 / 10  *3 =                         3/10
  • Last: The two end terms    (1/10 * 5/6 = 5/60                                              5/60

Now you can add. 21 + 5 is the whole number amount = 26

Add the fractions

  • 5/6 + 3/10 + 5/60 The lowest common multiple is 60
  • 50/60 + 18/60 +5/60 = 73 / 60 = 1 and 13/60

Add that to 26 and you get 27 13/60
