How many 1.1 centimeter lengths can be made from a string that is 5.093 centimeters long? Enter a numerical answer only.
Alexandra [31]
The number of 1.1 cm in 5.093 cm can be calculated through finding the ratio of:
(longer length)/(shorter length)
longer length=5.093 cm
shorter length=1.1 cm
thus the ratio will be:
5.093/1.1
=4.63
This means that 1.1 cm length will go into 5.093 cm length by a factor of 4.63

mezya [45]

Answer:

4 dimes and 8 quarters

Step-by-step explanation:

Let d = number of dimes.

Let q = number of quarters.

d + q = 12

10d + 25q = 240

       -10d - 10q = -120

(+)     10d + 25q = 240

---------------------------------

                  15q = 120

q = 120/15

q = 8

d + q = 12

d + 8 = 12

d = 4

Answer: 4 dimes and 8 quarters
