Answer:
12 dimes and 4 quarters
Step-by-step explanation:
If a quarter is 25 cents and a dime is 10 cents then:
There are at least 8 dimes, so we have at least 80 cents
And we know there is only 8 more dimes than quarters so the ratio 12 dimes: 4 quarters tells us that this expression is correct

Answer:
In the year 2010, the population of the city was 175,000
Step-by-step explanation:
If we rewrote this as a linear expression in standard form (it is linear, btw), it would look like this:

The rate of change, the slope of this line, is 11/2. If the year 2010 is our time zero (in other words, we start the clock at that year), then 0 time has gone by in the year 2010. In the year 2011, t = 1 (one year goes by from 2010 to 2011); in the year 2012, t = 2 (two years have gone by from 2010 to 2012), etc. If we plug in a 0 for t we get that y = 175,000. That is our y-intercept, which also serves to give us the starting amount of something time-related when NO time has gone by.
Answer:
50.265(correct to 5 significant figure)/ 16π
Step-by-step explanation:


=50.265(cor. to 5 sig.fig.)/ 16π
to find the arc length of a sector,we need to use πradius² times (sector's degree divided by 360degree).
