If it takes (a) men (b) hours to dig (c) holes, how many men are required to dig b holes in c hours?
docker41 [41]
Well, let's see . . .

You said that  (a) men can dig (c) holes in (b) hours.

So . . . It takes  (a) men  (b / c) hours to dig one hole.

And . . . It takes    One man  (a b / c) hours to dig one hole.

Now . . .  There are  (b) holes to be dug.

              It would take one man  (a b / c)·(b) = (a b² / c) hours to dig them all.

              But if you had 'x' men, it would only take them  (c) hours to do it.

So          c  =  (a b² / c)  /  x

           x c  =  (a b² / c)

           x     =  a b² / c²  men   . 

Now, I lost the big overview while I was doing that,
and just started following my nose through the fog.
So I have to admit that I'm not that confident in the answer.
But gosh durn it.  That's the answer I got, and I'm stickin to it.

Show that f(x)=(x-2)^3+8 is one to one algebraically
Lelu [443]
What im thinking is this: F(a) = f(b) so have 2 equations written and plug a into one and b in the other

(a-2)^3+8   = a^3-8+8 = a^3

                                             =            a^3 = b^3 square root both side = a=b
 <span>(b-2)^3+8  = b^3-8+8 = b^3


Thus it is 1:1.</span>

Rosa's test scores are 78, 92, 88, and 89. What must she score on her next test to have an average of 90? A) 95 B) 97 C) 99 D) 1
Morgarella [4.7K]

Answer: D

<u>Step-by-step explanation:</u>

Let x represent the score on her next test

\frac{78 + 92 + 88 + 89 + x}{5} = 90

(5)\frac{78 + 92 + 88 + 89 + x}{5} = (5)90

78 + 92 + 88 + 89 + x = 5(90)

                      347 + x = 450

                    <u> -347      </u>   <u>-347 </u>

                                x = 103
