Precision Testing (PTest) does fluid testing for several local hospitals. Consider their urine testing process. Each sample requires 12 seconds to test, but after 300 samples the equipment must be recalibrated. No samples can be tested during the recalibration process, and that process takes 30 minutes. They receive 150 samples per hour to test. What is PTest’s capacity to test urine samples (in samples per hour)? (round to the nearest integer)

i just took the test, the correct answer is .. 31.5 in.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!

i think it's b. 5.5

step-by-step explanation:

because if you subtract 2 from 7.5 that's what you

hope that . i might be wrong though =i
