Step-by-step explanation:
125%= 1.25
1.25 times 24= 30
Well, think of the dragonfly's speed as a ratio of miles/hours, thus making it 36/1 (as a fraction). Now to solve this, set the known ratio equal to the ratio you want to find and solve for the missing variable (x) which is hours. Cross multiply to find your (x) hours.
A molecule contains just one element while a compound contains more than one element.
Answer:
$72
Step-by-step explanation:
And the reason is because it said it costs $18 for 4 hours so each every hour you add $18
so therefore it means that 18 x 4 + 72
109° and 71°
Supplementary angles sum to 180°
let one angle be x then the other angle is x - 38, hence
x + x - 38 = 180
2x - 38 = 180 ( add 38 to both sides )
2x = 218 (divide both sides by 2 )
x = 109
the two angles are 109° and 109 - 38 = 71°
