## anonymous 5 years ago solve the formula for the specified variable: A=1/2bh for h

1. anonymous

Is it $A={1 \over 2bh}?$

2. anonymous

your solving for h

3. anonymous

I am asking if what I wrote above is the original expression?

4. anonymous

If so, then: $(2Ab)h=1 \implies h={1 \over 2Ab}$

5. anonymous

its A=1/2(one half)bh

6. anonymous

But if the original expression is: $A={1 \over 2}bh$ then: $h={2A \over b}$

7. anonymous

thank you!

8. anonymous

np.

9. anonymous

can you try and help me with some other?!

10. anonymous

Yeah.

the total cost in dollars for a certain company to produce x empty jars to be used by a jelly producer is given by the function C(x)=.07x=12,000. find C(90,000), the cost of producing 90,000 jars

12. anonymous

Is it C(x)=0.7x-12,000?

13. anonymous

A.) $63,000 B.)$75,000 C.) $12.70 D.)$90,012

14. anonymous

I don't want choices. You made a mistake in writing the formula. I want you to check it. Is +12,000 or -12,000?

15. anonymous

positive 12,000

16. anonymous

If so, then the cost of 90,000 jars is: $C(90,000)=0.7(90,000)+12,000=75,000$

17. anonymous

sorry for the misunderstanding thanks so much!

18. anonymous

You're welcome!

You could give me a medal :)
