90/139 is the only fraction not equivalent to 45/70.
To find if a fractions are equivalent, divide the numerator by the denominator for each fraction.
45/70=0.642857
27/42=0.642857
9/14=0.642857
63/98=0.642857
Notice how all of these get you the same number. However, when you divide 90 by 137, you get 0.64748, which is not the same as the others. Therefore, 90/137 is the fraction that is not equivalent to 45/70.
Answer:
Computing the sum of $5.89 and $1.45 we get: $7.34
Step-by-step explanation:
We need to explain, how can we compute the sum of $5.89 and $1.45?
Computing the sums of dollar amounts is same as computing the sum of simple decimal expressions. Each value will be added to its corresponding values and we will get the answer.
Computing the sum of $5.89 and $1.45
![\:\:\:\:\:\$ \:\:5.89\\+\$ \:\:1.45\\------\\\:\:\:\:\:\$ \:\:7.34](https://tex.z-dn.net/?f=%5C%3A%5C%3A%5C%3A%5C%3A%5C%3A%5C%24%20%5C%3A%5C%3A5.89%5C%5C%2B%5C%24%20%5C%3A%5C%3A1.45%5C%5C------%5C%5C%5C%3A%5C%3A%5C%3A%5C%3A%5C%3A%5C%24%20%5C%3A%5C%3A7.34)
So, we will start adding from right side, 9 will be added with 5 and we get 14, 1 will be given carry and 8 will be added by 4 and add the carry we get 13, 1 will be given carry and 1 will be added by 5 and add the carry we get 7
So, Computing the sum of $5.89 and $1.45 we get: $7.34
Answer:
1st : neither linear nor nonlinear
2nd: nonlinear
3rd: linear
4th: both linear and nonlinear
I am not sure about all of them, but it says to write the answers in simplest form, but number 4 is not in simplest form.
4/12 can be simplified to 1/3
<span>3.the function is f^2(4) = f(3) = 1/2 x 1 = 2.5
i believe thats right still working on the others</span>
