Answer 1
Answer:

Answer: a. 12.66 cm

Step-by-step explanation:

Given value: 12.655 cm

Here in the given value there area five significant figures.

If we need to round the value to four significant figures then we need to round the given value to the nearest hundredth.

Since, the last digit (hundredth and thousandth place) is 55 which is nearest to 60.

Then the the required answer after round off to the  nearest hundredth will be :-

12.660\ cm=12.66\ cm
Answer 2
Answer: A, 12.66 cm as 55 is above 50 which mean you have to round it to the next tenth figure which is 6.

Help ?!

Answers

Its solve the system of equations. you can do substitution or elimination.

There are two kinds of solving but elimination seems best for this system:

-2x-9y=-25
4x+9y=23 (multiplied it by -1 so you can eliminate the variable "Y")
---------------
2x=-2
x=-1 (divide by 2 on each side)

-2(-1)-9y=-25 (insert what you received for what "X" is)
2-9y=-25 (simplify)
-9y=-27 (subtract 2 on each side)
y=3 (divide each side by -9)
Turn them into y=mx+b form
(-2/9)x+25/9 and (-4/9)x+23/9.
Then equate them to each other
(-2/9)x+25/9=(-4/9)x+23/9
Then solve of x
(-2/9)x+(4/9)x = (23/9) - (25/9)
X = -1
Then plug in X and solve for y
Y = (-2/9)(-1) + (25/9)
Y= (27/9)
Y= 3
So your solution is (-1,3)

Answer:

9p2 + 6p - 8  -12 = 9p^2 + 6p -20

Step-by-step explanation:

You can't change 9p^2 or 6p as we do not know what p is equal to but

-8 + (-12) = -20

So if we put it all together we get 9p^2 + 6p -20

A company has two electric motors that consume varying amounts of power. The power consumed by each motor is a function of the time (t in minutes) for which it runs. The cost of power (in $) to run one motor is given by the function `C_a(t) = t^2 - 2t + 5`. The cost of running the second motor is given by `C_b(t) = 3t + 2`. Which function gives the total cost of running both motors?
