Answer:
12 fives and 18 tens
Step-by-step explanation:
solving this we need 2 different equations
one for he total bills and one for the total money
x+y=30
that is total bills
5x+10y=240
combining both equations we can use elimination method and get
12 five dollar bills and 18 ten dollar bills
Answer:
8.91m/s²
Step-by-step explanation:
If you were referring to the question :
If a 2.2 kg textbook weighs 19.6 newtons on Venus, what is the strength of gravity on that planet then read on.
Weight is the force of gravity on an object and it can be computed using the formula:
W = mg
where:
W = weight (N)
m = mass (kg)
g = acceleration due to gravity
So we know the weight and the mass of the object, all we do is plug it into our formula and solve for what we do not know.
![W = mg\\\\19.6N = (2.2kg)(g)\\\\ \dfrac{16.6N}{2.2kg} = g\\\\8.91m/s^{2} = g](https://tex.z-dn.net/?f=W%20%3D%20mg%5C%5C%5C%5C19.6N%20%3D%20%282.2kg%29%28g%29%5C%5C%5C%5C%20%5Cdfrac%7B16.6N%7D%7B2.2kg%7D%20%3D%20g%5C%5C%5C%5C8.91m%2Fs%5E%7B2%7D%20%3D%20g)
Answer:
answer is 4.15
Step-by-step explanation:
you just add the numbers its no different than a normal addition problem for the most part.
I see two ways to do it.
First, you have to understand that when you see a 'complex fraction' like this, the top number is a numerator, and the two bottom numbers are both denominators.
Way-1:
Take the top fraction . . . 2/2 . That's equal to 1 . So the whole thing is <em>1/3</em>.
Way-2:
Multiply the bottom two denominators. Then the whole thing is 2/(2·3) . That's the same thing as 2/6 . Simplify that, and you have <em>1/3</em> .
