Per 1/2 an hour it is changes by 5 so the constant rate would be: 5 inches per 1/2 an hour

From the given question we come to know of certain number of facts and they are:
At 1:00 PM the water level of the pond was = 13 inches
At 1:30 PM the water level of the pond was = 18 inches
At 2:30 PM the water level of the pond was = 28 inches
From the above given facts we can easily find the amount of water changing every half an hour.
Amount of increase in water from 1:00PM to 1:30 PM = (18 - 13) inches
                                                                                       = 5 inches
Amount of increase in water level from 1:30PM to 2:30PM = (28 -18) inches
                                                                                             = 10 inches
From the above two deductions we can come to the conclusion the the constant rate of change in water level is 5 inches for every half an hour.

HELP ME PLEASE!!!!<br> ΔAXY ~ ΔABC. What is the value of BC
emmasim [6.3K]

Answer:

BC = 28 \frac{1}{3} ft

Step-by-step explanation:

Given that the triangles are similar then the ratios of corresponding sides are equal, that is

\frac{AX}{AB} = \frac{XY}{BC} , substitute values

\frac{12}{20} = \frac{17}{BC} ( cross- multiply )

12BC = 340 ( divide both sides by 12 )

BC = \frac{340}{12} = \frac{85}{3} = 28 \frac{1}{3}

Factor completely
ZanzabumX [31]
Use the (-b + - sqrt( b^2 - 4ac) ) /2a Formula.
a = 1 b= 10 c= 24
 so you get .. (x+6 )(x+4) A
