Answer:
If you are rounding to the nearest tens the smallest number is 45. If you are rounding to the nearest whole number, the smallest number is 49.5
Answer:
Length = 72 mm
Width = 46 mm
Ratio = 72:46 = 36:23
Step-by-step explanation:
72 and 36 both are divisible by 2. so when we divide them by two we get 36 and 23. we can divide both the sides only with the same number, but 36 and 23 have no common factors. so we leave it here and this is the answer.
A reasonable number between 18 and 23 is 20. 69 minutes is 3 times 23 minutes, so we multiply the 20 by 3, getting an estimate of 60 cars.
Answer:
-13
you're basically adding -3 and -10 because they're both negatives
C. 5/15
First, change 3/7 to have the same denominator as 1/14.
3/7=6/14 because 7•2=14 (denominator) 3•2=6 (numerator)
Next, subtract 1/14 from 6/14.
6/14-1/14=5/14
