<h3>
Answer: 4900 (choice D)</h3>
===================================================
Work Shown:
1 km = 1000 m
3.5 km = 3500 m ............. multiplying both sides by 3.5
(70 paces)/(50 m) = (x paces)/(3500 m)
70/50 = x/3500
7/5 = x/3500
7*3500 = 5x .............. cross multiply
5x = 7*3500
x = (7*3500)/5
x = (7*5*700)/5
x = 7*700
x = 4900
Ann takes 4900 paces to walk 3.5 km
The flower beds occupy:
100% - 20% = 80%
We then have the following rule of three:
25 feet ^ 2 ------> 100%
x -----------------> 80%
We clear the value of x:
x = (80/100) * (25)
x = 20 feet ^ 2
Answer:
the flower beds occupy 25 square feet
Answer:
A
Step-by-step explanation:
3. yes because 15 divided by 5 and 27 divided by 9 both result in the same answer; 3.
4. No because 3/4 is not a whole number, while 4/3 is. For this to be an equivalent ratio, the second number would have to be something like 6/8.
