The product of the page numbers on two facing pages of a book is 156. Find the page numbers

Gnoma [55]

Let x be the page number then x+1 would be the other page number (because the pages are two facing pages which means they follow on consecutively)

Then

(x)(x+1) = 156

x^2 + x - 156 = 0

x = 12 or x = -13( but x can't be a negative number)

so x = 12

and the next page is 13

$3-2i/5+i$

$\frac{3*5+(-2)*1)+(-2*5-3*1)i}{5^2+1^2}$

$\frac{13-13i}{26}=\frac{1-i}{2}$

$=\frac{1}{2}-\frac{1}{2}i$

Shaquil needs to borrow $400. The loan company charges him $80 in fees for the loan. Shaquil calculates that the annual percenta

lesya [120]

Answer:

(B)

Step-by-step explanation:

PRINCIPAL AMOUNT(p) = $400

RATE (r)= 250% = 2.5

INTEREST = $80

t = time (in days) = t/365

By using the formula,

r = $\frac{i}{pt}$

2.5 = $\frac{80*365}{400*t}$

t = $\frac{364*80}{400*2.5}$

t = 29.2

t = 29 days (approx)

Hence option (B) is correct.
