Answer:
r=244745.8 (approximately)
Step-by-step explanation:
r=x²/y
ry-x²=0
r(59000)-(380000)²=0
r=380000²/59000
r=144400000/59
r=244745.8 (approximately)
Answer:
a) Experts estimate that about 68 percent of the world's population has lactose malabsorption. Lactose malabsorption is more common in some parts of the world than in others.
b) In the United States (ignoring other groups and people who consider themselves to belong to more than one race), 82% of the population is white, 14% is black, and 4% is Asian. Moreover, 15% of whites, 70% of blacks, and 90% of Asians are lactose intolerant.
So ok
reduced by 13% each times 100-13=87 so 87 % of previous
so
t=time elapsed
I=initial amount
C=future amount
C=I(percentrate)^t
so
