Answer:
3220
Step-by-step explanation:
5x4=20
3x6=18
20+18=38
1=60
38x60=2280
20x25=500
2280+500=2780
6000-2780=3220
By proportion. First write down the given information systematically:
[1000] drops of liquid equals (1 fl. oz.)
(100) drops of liquid equals ? oz
For problems that are directly proportional, we cross multiply the numbers in the bottom left and top right (in parentheses), divide by the number across ( in square brackets) from the unknown, namely:
Answer:
100 drops * 1 fl. oz / (1000 drops) = (100/1000)* 1 fl. oz = 0.1 fl. oz.
Answer:
the price would be $3.93
Step-by-step explanation:
18%of 3.33 is .6 so just add that to the original amount
Step-by-step explanation:
Assuming the speed of car B to be x and the speed of car A to be x+20
<u>1</u><u>5</u><u>6</u> = <u>2</u><u>0</u><u>8</u>
x. x+20
156(x+20)= 208x
156x+3120=208x
3120=208x-156x
3120=52x
x=60
The speed of car A is (x)= 60
The speed of car B is(x+20)= 80
