Answer:
9.7x10^-5
Step-by-step explanation:
You have to have one number in the ones place, so moving that forward, would mean that there would need to be one more power of ten to get it to where it needs to be.
Answer:
the answer is 1/4 because if you add up all of the numbers you get 100 which is easy to get a fraction out of and because the orange juice proportion is 25 you get 1/4
Answer:
question 19 = no solution because not enough information
question 20 = 18 for volume
Step-by-step explanation:
question 19:
cylinder formula
surface A =2πrh+2πr2
2π times 9 times 7 + 2π times 9 times 2
SA = 508.938009882
volume equals 395.840674352
question 20:
biggest one,
4h﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4
V=18 IS the volume
Answer: No
Solution:
Substitute the values of x & y into the first equation
6 -(-1) = 3
6 + 5 is NOT equal to 3
Therefore we can say this is not true
For this to be true, when substituting the values of x & y, the equation must be true for BOTH equations. Since it’s not true for the first equation it doesn’t matter if it’s true or not for the other equation.
I hope this helps!
