Volume of a cylinder formula is
Answer:
"The values for y are square roots of negative numbers"
Step-by-step explanation:
The steps shown are correct. But at the end we can see that we have to <em><u>"take the negative square roots"</u></em>.
This means we have to take the square root of -1. In the real number system, we CANNOT take the square root of any negative number. Hence, there is NO SOLUTION to the system.
2nd answer choice, "The values for y are square roots of negative numbers", is right.
Answer:
16
Step-by-step explanation:
each pound has 3.6 cups
1/4 of a pound can be multiplied
3.6 x 1/4 = 0.9
then we subtract 4 - 3.6 = 0.4 say if the question was for one pound
But we have to find 14.4 cups instead as;
3.6 x 4 = 14.4 = 4 pounds
We go back to 0.9 are first smaller serving = 1/4 cup
14.4/0.9 = 16
Answer:
A
Step-by-step explanation:
Owing someone meand you have to give them money and therefore is represented ad a negative number.
-14 + (-7) is the same as -14 - 7
since, average of doctors using brand x aspirin is 3 out of 5
if we consider one part then one part will be equal to 3/5
total survey consists of 2000 doctors then to find the brand x aspirin we can use the unitary method that is multiply the total number by one part
2000 x 3/5= 400 x 3
= 1200
so, total 1200 doctors are using brand x aspirin
