Answer:
Step-by-step explanation:
First off, let's change everything to a common denominator. This will allow us to add the fractions!
To find a common denominator, we find a number that both 4, 28, and 1 can go into. 28 is the best choice, as 4 goes into it 7 times, 28 goes into it once, and 1 goes into it 28 times.
Let's change the first fraction into a number with a denominator of 28!
= 1. Multiplying a number by one doesn't change its value.
The second fraction, 
, already has a denominator of 28, so we don't have to do anything with it.
Now to the third number, -1:
Now, let's add them all up!
One last step, to simplify:
<h2>Your answer is 1/14!</h2>
Answer:
1, 2, and 4
Step-by-step explanation:
Answer:
taking z as the reference angle XY becomes perpendicular and YX becomes base thus SIN Z= P/H
SIN Z = 30/50
therefore sin z= 0.6
X to the power of 2 + 4x +5
Answer: The instrument weigh 204 ounces on Earth.
Step-by-step explanation:
Since we have given that
Instrument weighed on the moon = 34 pounds
As we know that
The force of gravity on Earth is 6 times greater than on the moon.
So, the weight of instrument on the earth is 6 times the weight on the moon.
Mathematically, it is expressed as
Hence, the instrument weigh 204 ounces on Earth.
