9. A store has T-shirts on sale at 2 for $5.50. At this rate, what do five T-shirts cost?

Answer 1

(1) 5 3/5: 2 1/10=28/5 : 21/10=4/1:3/2 =4 :1 1/2 (2)7 dimes :3 quarters =70 cents:75 cents=14:15 (3) Marc :Angelina= 3hrs :150 mts =180 mts :150 mts. =6:5 (4) Ratios of similar things only can be found out.no ratio is possible bet weight and area. (5) 4.75/5= 0.95 whereas 19.92/20=0.996 Therefore the first rate is better.(6) 8:15::24:45 OR 8:15=24:45 OR 8/15=24/45 (7) As 5*120 is equal to 8*75 the ratios are proportional. (8)As 12*1240 is not equal to 9*8329 they are not proportional and so you cannot put an '=' sign between these two ratios.(9) it is $2.75 for each shirt.So 5 shirts cost $2.75X5 or $13.75

Answer 4

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.

Answer 5

It seems you hardly know anything, should you prefer to be spoon-fed every time then you will never grasp the facts. I can work out all these problems for you, but that means you will continue bringing more. Do 6 and ask 4, that way you will become a genius.

Answer 6

This is your homework. Do it on your own. If you CAN NOT do one, ask then and only then.
