You find the area of a triangle by using 1/2*b*h where b is the base and h is the height. since we already know the area is 20 and the height is for you plus them in so the problem would be 20= 1/2 (b) (4) then you multiply what you know together to get 20= 2b and then isolate the b by dividing both sides by two so the base should be 10 m

9ax+9b-6=21 <br><br> based on the equation above what is the value of ax+b
klemol [59]
We have 9ax+9b-6=21.

We add 6 to both sides. 9ax+9b=27.

Now, to solve for ax+b, we factor out and divide by a 9 to get

9(ax+b)=27  \\ ax+b=3.

A manufacturing operations consists of 12 operations. However, five of the 12 machining operations must be completed before any
shutvik [7]

Answer:

604800 possibilities

Step-by-step explanation:

There are two sets.

The first set is for the first five machining operations. This set has the following operations: A,B,C,D,E

The first operation to be made can be any of them(A,B,C,D,E). The second will be any of the four remaining ones, the third will be any of the three remaining and so on...

So for the first set there are 5*4*3*2*1 = 5! = 120 possibilities.

Now for the second set, the same logic is applied.

There will be 7*6*5*4*3*2*1 = 7! = 5040 possibilities.

Now taking into account all the 12 operations, separated by set, there will be 120*5040 = 604800 possibilities.

You can understand this calculus as that for a simple possibility of the first set, there are 5040 possibilities of the second set. The are 120 possiblities in the first set, so we have the multiplication in the paragraph above.

You work at a local grocery store. Your paychecks over the past 6 weeks were $56.05, $41.50, $22.50, $52.90, $49.85 and $31.00.
ICE Princess25 [194]
The arrangement in order would be 22.5, 31, 41.5, 49.85, 52.9, 56.05
the mean would be $42.30 (Added all and divided by 6)
the median would be $45.68 (41.5+49.85=91.35/2= 45.675)
there would be no mode.
