The total number of fish bought was 320. And you know she bought two types of fish. The best way to solve this is guess and check. It would be the fastest. So she bought 7 times as many trigger-fish as parrot fish that means the number of trigger-fish bought was 7p. This means 320 = 7p +p. So all you do is take educated guesses for the number of parrot fish and check if it is right. So if she bought 50 parrot fish. 7(50) + 50 = 400. Close but a bit high. Lets keep guessing. 7(35) + 35 = 245. So now we know the answer is between 50 and 35. So lets try 40. 7(40) + 40 =320. That works so we know she bought 40 parrot fish and 280 trigger-fish.
Answer:
C
Step-by-step explanation:
V=4
/3πr3
3000=1 1/3*3.14*r*r*r
3000=4.18666667*r*r*r
716.560509=
Cube root the number
8.94851471456=r
TSA=4
TSA=4*3.14*8.94851471456*8.94851471456
TSA=1006.26
Since we used different numbers for pi and I rounded our answer will be different but the answer is C
Answer:
Step-by-step explanation:
A system has no solution if the 2 (or more) functions that make up the system do not intersect. The only pair of functions here that do not have an intersection is found in D. You could graph these 2 on a graphing calculator to see that this is true.
