If the ratios form a proportion, the ratios will be equal. first we'll simplify the ratios:
14/21
divide top and bottom by 7
2/3
26/39
divide top and bottom by 13
2/3
ss you can see now, the ratios are indeed equal, so they do form a proportion
To 3 decimal places.
128.59943
Count three places to the right after the decimal point. The third digit is 9, and the fourth is 4. Since the 4th is not up to 5, we leave the 9 that way and so we can not round up the 9 to 10.
So it becomes = 128.599
Thanks.
Answer:
Simplified = 4 + 3
, Decimal = 8.2426...
Step-by-step explanation:
Using a calculator divide 2x10^8 by 5x10^6 and you get 40 therefore it is 40 times larger
Answer:
18 since f(3)=18
Step-by-step explanation:
f(x)=2x^2 is give as our function. To find f(3) we need to replace x with 3.
f(3)=2(3)^2 (Replaced x with 3.)
f(3)=2(9) (Did 3^2 which was 3*3=9)
f(3)=18 (Did 2(9) which was 18)
