Marco can finish a jigsaw puzzle in 3 hours. Working together with Cliff, it takes them 1 hour. How
vovikov84 [41]

Macro can finish the puzzle in 3 hours. We can say that her speed for working is 1/3 or 1/3 puzzle per hour.

Now if they work together, this turns into 1 puzzle per hour.

That must mean that Cliff would be doing the other 2/3 of the puzzle while Macro does his 1/3 in that hour. If Cliff has a speed of doing them 2/3 per hour. Then it would take 1 and a half hour to finish 1 whole puzzle.

90% of a number is x . What is 100% of the number? Assume x&gt;0
mariarad [96]

Step-by-step explanation:

Let the required number be n

\therefore \:  \frac{90}{100}  \times n = x \\  \\ \therefore \:  \frac{9}{10}   \\  \\  \therefore \:n = \frac{10}{9} x \\  \\  \therefore 100\% \: of\:n = \frac{10}{9} x \times 100\% \\  \\  = \frac{10}{9} x \times \frac{100}{100}  \\  \\  =  \frac{10}{9} x  \\

NOTE: A number is always 100% in itself.

Help please! factoring polynomials
alexgriva [62]

Answer:

B

Step-by-step explanation:

you can use foil and the graph,

because you can see (in the graph) that the lines intersect at 1 and 4.

just use foil to help figure out which matches the slope.

something else (the normal way) is find which 2 numbers equal to the last coefficient, in this case it can be

-2 and -2,  2 and 2, 4 and 1 or -4 and -1, multiply them and if they make up the last coefficient, and added it equals the second coefficient it is correct.
