Let there be 2x science and 5x art books
<span>science books sold = 2x × 0.2 = 0.4x </span>
<span>science books unsold = 2x – 0.4x = 1.6x </span>
<span>art books sold = 5x × 0.2 = x </span>
<span>art books unsold = 5x – x = 4x </span>
<span>total books unsold = 1.6x + 4x = 5.6x </span>
<span>5.6x = 2240 </span>
<span>x = 400 </span>
<span>2x science = 800 </span>
<span>and 5x art books = 2000 </span>
Answer:
not sure but I think it is no lines of symmetry.
Step-by-step explanation:
the background with trees when folded together don't line up. they aren't similar.
Answer:
it is .25 :)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~``
25% off translates into 0.25($30) = $7.50 off.
A faster way to determine the sales price is to subtract 0.25 from 1.00 and then mult. the regular price by the result: sales price = 0.75($30) = $22.50 (answer)
Answer: Our required probability is 0.067.
Step-by-step explanation:
Since we have given that
Number of days in a year = 365
Number of years = 10
So, Number of days in 10 years = 365 × 10 = 3650
Number of unprovoked shark bites in Florida = 246
so, Probability that there will be at least one unprovoked shark bite on a given day is given by
Hence, our required probability is 0.067.
