Percent change formula:
C = x - x
2 1 / x
1
To calculate percent change we need to take the difference between the starting value and final value, divide by the absolute value of the starting value, and multiply the result by 100.
1. 72 is a 33.333% decrease of 108. Round is 33%.
2. 90 is a 20% increase of 75. Round is 20%.
3. 49 is a 75% increase of 28. Round is 80%.
Remember you can do anything to an equaiton as long asyou do it to both sides
4v+18≥6v+10
minus 4v both sides
4v-4v+18≥6v-4v+10
0+18≥2v+10
18≥2v+10
minus 10 both sides
18-10≥2v+10-10
8≥2v+0
8≥2v
divide both sides by 2
8/2=(2v)/2
4≥(2/2)v
4≥1v
4≥v
v≤4
Answer:
No becasue she only has 22 yard and the total she needs is more than 23 yards
No, she's no good at math...
2.99/6 = about fifty cents a drink.
Distance = Y=1.7t
L = 6sin(tan^-1(d/8))
L = 6sin(tan^-1(1.7t/8))
