Answer:1752
Step-by-step explanation: So what you need to do is to multiply the number of copies that the small copier makes with the 4 because it says that it makes it 4 times what the smaller copier does.
Answer:
50 times greater
Step-by-step explanation:
If there are two numbers A and B, where A is greater than B,
If we want to find how many times greater A is to B, we simply divide, so that would be
A/B
Now, we have
and
We simply need to divide to find how much greater is the first number than the second number. Remember dividing numbers in scientific notation:
Thus, we have:
So the first number is 50 times greater than the second
Answer:
7^2
Step-by-step explanation:
there is one law of exponent, where if you're dividing 2, and the base is the same, you can just subtract the exponents so-
We can automatically see that we are dealing with a percent decrease because we are going from a smaller to a bigger number. We need to first find what percent of 140the number 84 is. to do this we can set up the following equation:
140/84=100/x (this equation is basically saying if 140 is 100(%) what would 84 be?)
solving for x here gives us x = (84 X 100)/140 = 60, so 84 is 60 percent of 140 which means 140 decreased by 40 percent.
Let me know if I can clear anything else up.
