Answer:
80
Step-by-step explanation:
5x8 hats=40/8 yard which equals 5 yards cause 40/8=5
So you know that 5 yards can make 8 hats.
Then do 5x16 because 10 yards is double the size as 5 to get 80.
Answer:
C
Step-by-step explanation:
40 minutes every day for a week is 40 multiplied by 7, which is 280. Dividing that by 60 is 4 remainder 40, so 4 hours and 40 minutes.
Answer:
Thomas' real income now is half that it was (nominal income decreased by half or prices doubled)
Step-by-step explanation:
If you graph both cases you will see that the shift is parallel between one case and the other.
Changes in relative prices (this is, if only one of the goods change prices), would cause a rotation in the budget line
Answer:
11 half years
Step-by-step explanation:
The formula for compound interest is
A = P(1+r/n)^(nt), with r representing the interest rate, n being the number of times interest is applied over the time period, and t being the amount of time periods.
If we make the time period a half year (so interest is compounded once per time period), n=2. Then, our interest rate is 7%, or 0.07 (to convert from percent to decimal, simply divide by 100). Our starting amount is 500, and we want it to double, making it 1000. Our formula is thus
1000 = 500 (1+0.07)^(t)
divide both sides by 500
2 = (1+0.07)^(t)
2 = (1.07)^(t)
Using logarithms, we can say that
and using a calculator, we get
10.24 = t
Since interest is only compounded once per time period, though, we have to round up to make sure it doubles, so t = 11
the answer is C (0,0) because thats the only choice that is in the blue shaded area on the graph
you can also test it by plugging in 0 into the equation and your answer will be true meaning that (0,0) is a correct answer
