Answer:
its going to be the one with the line going down
Step-by-step explanation:
The answer is 2.2108
Solution:
first equation:
h = -0.2d² + 2.25d-d + 6h = 21.77
2nd equation:-d + 6h = 21.77d = 6h - 21.77
Then substitute:h = -0.2(6h - 21.77)² + 2.25(6h - 21.77)h = 3.9968
Answer:d = 2.2108
Well pie is 3.14 etc.
And the way to find that out is by:
~Using the formula.
~To find out what the circumference is you have to use this formula<span>
C= π*d =2*π*r
</span>~Pi<span> equals a circle's circumference divided by its diameter.
</span>~If you plug in the numbers in a calculator the numbers should be 3.14.
Answer:
0.0057
Step-by-step explanation:
- Narrow it down.
- The point P is between 5 * 10^-3 and and 6*10^-3
- When you go to the bottom line, P is on the 7th division from the left.
- Going from left to right increases P
- P is on a line that goes between 5 and 6. Each division is 1/10. So P is in the tenth place.
- One of the answers is 5.7 * 10^-3
- The other answer is .0057
- I really don't know which one to choose because we are given no direction. As a programmer, 0.0057 would be easier to program. I would choose it.
- If it is not correct, then 5.7 * 10^-3 is the answer.
The answer is h = 2A/(b1 + b2).
In order to find this, use all the methods for solving typically used in these types of equations. See the below example.
A = 1/2(b1 + b2)h ---> Multiply both sides by 2.
2A = (b1 + b2)h -----> Divide both sides by (b1 + b2)
2A/(b1 + b2) = h
