Control = group with no music / maybe no variable?
Manipulated/independent variable = Number of tomatoes being grown
Dependent/responding = Number of tomatoes produced by each plant
Conclusion = Use four parts... Was your hypothesis correct or not and why...Cite numbers/evidence from experiment.... Were the results reliable?.... any improvements to be made
Answer:
87.5%
Step-by-step explanation:
1) divide 7 by 8 which gives you 0.875
2) move the decimal in 0.875 two spaces to the right which makes it as a percent of 87.5%
Electromagnets are devices that create a magnetic field through the application of electricity. Strong electromagnets are used to lift, move and drop heavy objects, such as vehicles. Electromagnets have advantages over permanent magnets. When the current is switched off, the electromagnet will lose its magnetism. The car will fall back to earth and we need that when we move cars in a junkyard. With a regular ( permanent ) magnet it would be much harder to do.
Answer: A. True
Answer:
Hi there!
Your answer is:
the number is 68
Step-by-step explanation:
(18-n) /2 = -25
×2
(18-n) = -50
-18
-n = -68
/-1
n= 68
Plug it back in!
(18-68) /2 = -25 ???
-50/2 = -25 ✓✓✓
Hope this helps
Answer:
tanA=34⟹sinA=332+42−−−−−−√=35
Now, we have
sinAcosA=tanA
⟹3/5cosA=tanA
⟹cosA=13×54×3
⟹cosA=45
⟹cosAsinA=4×35×5=1225
Step-by-step explanation:
