Okay we know that tangent-chords creat 90 degree angles so what we have is a right triangle with a base of 9 and a height of 12, so do Pythoagoreas Theorem and we have 81+144=225 square root of 225 is 15 and that is AJ
Answer:
252 cm²
Step-by-step Explanation:
=>Given:
r = 4.9 cm, and h = 3.3 cm of a solid cylinder, π = 3.14
=> Required:
Total Surface Area (T.S.A) = 2πrh + 2πr²
T.S.A = 2*3.14*4.9*3.3 + 2*3.14*4.9²
= 101.5476 + 150.7828
= 252.3304
= 252 cm² (approximated)
72 fish total. 12 fish in each tank.

n=Number of fish tanks
*If I got it wrong, let me know*
It could have been oh so much easier to choose the best choice
if you had but told me what the choices are.
The most appropriate choice depends on why you want to know,
and what you plan on doing with the information. Are you going to
use it to help you decide ...
-- How many entrance gates to build ?
-- How many ticket-takers to hire ?
-- What size parking lot is needed ?
-- How much ice cream and beer to stock in the park each day ?
-- How many rest rooms the park needs ?
-- How many costumed characters should roam the park ?
-- How many police should patrol the park ?
-- How much the park needs to be advertised in the next 6 months ?
-- Whether it will pay to build another similar park somewhere else ?
Depending on the application, here are some appropriate units
to describe the rate at which people are entering a theme park:
-- visitors per minute
-- visitors per hour
-- visitors per day
-- visitors per week
-- visitors per month
-- visitors per year
Answer:
Honestly im not sure
Step-by-step explanation:
5.2°C = (273 + 5.2)k = 278.2k
Change in temperature = 368k -278.2= 89.8k
q (heat energy) = MCp∆T
When Cp of water =1046J
q = 7.59 g × 1046J × 89.8k
= 712, 934.772Jgk-1 = 713kJgk
When Cp of water =250cal
q = 7.59 g × 250 × 89.8k = 170kCalk
