Let those numbers be a and b

a+b = 25 -----(i)
ab = 154 -----(ii)

from (ii)
a = 154/b

by substituting for "a" in (i)

a + b = 25
(154/b) + b = 25
( 154 + b^2)/b = 25
154 + b^2 = 25b
154 + b^2 -25b =0

now, arrange the terms

b^2 - 25b + 154 = 0
b^2 - 14b - 11b + 154 =0
b (b-14) -11 (b-14) =0
(b-11)(b-14)= 0


now find the value for b

b -11 =0
b = 11
and

b-14=0
b = 14


b equals either 14 or 11

and a = 154/b
if b = 11 then, a = 154/11 = 14
if b = 14 then, a = 154/14 = 11


so, the value of a and b are 11 and 14.

so, those numbers are 11 and 14.

A water storage tank has the shape of a cylinder with diameter 14 ft. It is mounted so that the circular cross-sections are vert
4vir4ik [10]

Check the picture below.

neverminding for a few seconds the volume of the cylinder, the percentage in the height used by the water will be the same as the percentage of its volume.  We know the total amount or 100% of the height is 14, so what is 11 in percentage?

\begin{array}{ccll} amount&\%\\ \cline{1-2} 14&100\\ 11&x \end{array}\implies \cfrac{14}{11}=\cfrac{100}{x}\implies 14x=1100 \\\\\\ x = \cfrac{1100}{14}\implies x = \cfrac{550}{7}\implies \boxed{x \approx 78.6}

Simplify without using the absolute value sign<br><br> | x- ( - 18) | if x &gt; - 18
slega [8]
The expression would be > 0.

Subtracting a negative is the same as adding a positive; therefore -18--18 = -18+18 = 0.  Since we know that x>-18, 0 is below anything we could get from this.
