1st page: 580
2nd page: 576
in the 1st two pages: 580+576 = 1156
total word = 2000
total word = words written + words to write
2000 = 1156 + words to write
subtract 1156 from each side
2000-1156 = words to write
844 = words to write
Choice D
Answer: A. 1.01 Same as 1 1/100 fractions are rational
B. 57 Integers are rational. (Invisible implied denominator is 1)
Step-by-step explanation: c might be, but the denominator is not specified-- or maybe / is supposed to mean square root. So probably not.
D. NO, non-repeating decimal numbers are irrational
(1/2) / (1/4) = 1 / x......1/2 wall to 1/4 hr = 1 whole wall to x hrs
cross multiply
(1/2)(x) = (1/4)(1)
1/2x = 1/4
x = 1/4 * 2
x = 2/4 reduces to 1/2....so it will take 1/2 hr (or 30 minutes) to paint the whole wall.
Bear in mind that, is an isosceles
right-triangle, so, one angle is 90°.
