Answer:
1080
Step-by-step explanation:
Firstly, if he is paying 50 per month, we need to know the number of months it would take him to finish paying the money. Hence that would be 800/50 = 16 months
Now we know there is a surcharge of 17.5 for each month he owes a balance. The total balance he is to pay is thus 16 * 17.5 = 280
The total cost of the jacket is thus 800 + 280 = 1080
Answer:
32
Step-by-step explanation:
f(6)=6^2-4
f(6)=36-4
f(6)=32
Suppose we have the repeat decimal 0.123232323.... or 0.123 with a line over the repeated part (check the diagram)
- The first thing we need to do is identify the part of the decimal that repeats, 23 in our case.
- Second, we are going to assign a variable to our original decimal:
.
- Third, we are going to multiply both sides by a power of ten whose denominator will be the number of repeating digits. We know that we have 2 repeating digits (23), so we are going to multiply both sides by
, and
is just 100; therefore we get:
- fourth, subtract our original equation from the second step from the one from above:
Now we can cancel the repeated decimals to get:
- Last but not least multiply both numerator and denominator by a power of ten equals to the decimal digits in the numerator:
We now know how to convert a repeating decimal to a fraction.
For the reasoning, I think that you said it well, you should restate your answer, for an example, start off like this: I agree with Diego because... and for number five, I'm not too sure, sorry.
f(x) = 6 * 9 = 54 f(x)=54
f(x) = 6*37=222 f(x)=222
f(x)=6*109=654 f(x)=654
f(x)=6*6=36 f(x)=36
