2. The ratio of 7 dimes to 3 quarters
3. Marc took 3 hours (h) to mow a lawn while Angelina took 150 minutes

7. Determine whether each pair of fractions is proportional.

9. A store has T-shirts on sale at 2 for $5.50. At this rate, what do five T-shirts cost?
10. If a person jogs at a rate of 5 mi/h for 3 h in a week, how many calories do they
burn?

Answer 1

1. 28/5 to 21/10 or 5.6 to 2.1 or 2.67
2. 70 to 75 or 14 to 15 or 0.93
3. 180 to 150 or 6 to 5 or 1.2
4. i think it would be 40
5. the first one would be a better buy: There is two ways of doing it:1. divide 4.75 by 5 and divide by 19.92 by 20. 2. multiply 5 and 4 to get 20 using that proportion multiply 4.75 by 4 to see if it is less than or greater than 19.92
6. 8/15 = 24/45 cross multiply 8 and 45 which = 360 and cross multiply 15 and 24 which = 360. 360 = 360 so the proportion would be 0.53 i think
7. Yes they are equal 75/120 reduced = 5/8
8. No
9. $13.75
10. insufficient information How many calories are burned in when you run 15 miles, I do not know

I tried my best on all of these answers and I think they are all right. I am sorry if any are wrong and hope this helped you.

Answer 2

I select just a few questions only:
4.) 240pds : 6lawns
=> 240/6 : 6/6
=> 40 : 1

5.) 5lb : 4.75
=> 5/5 : 4.75/5
=> 1 : 0.95

20lb : 19.92
=> 20/20 : 19.92/20
=> 1 : 0.996

So it is better to buy 5lbs if sugar for $4.75

7.) 5/8 : 75/120
=>0.625 : 0.625

So the pair of fractions are equal

9.) 2 : 5.50
5 : x

Cross multiply the ratios:
2x = 5.50*5
2x = 27.5
x = 13.75
So five T-shirts cost $13.75

Answer 3

I see your combination up - A = PiR^2 precise? properly, section = Pi (radius squared), the place you placed the radius as 40 8. The Diameter is 24 cm, precise? properly, interior the formula, radius is barely 0.5 of the diameter, so which you ought to be using 12^2, no longer 40 8^2 Your formula ought to look like this: section = Pi(3.14) * 12^2 That'll provide you the the ideal option answer.
