Answer:
11.61 in
Step-by-step explanation:
the screen when divided diagonally, forms 2 right triangles
diagonal = hypotenuse = 16
16^2 = 11^2 + w^2
w^2 = 135
w = 11.61
Answer:
No, because the cone has a smaller volume than the ice cream
Step-by-step explanation:
V=4
3πr3=4
3·π·33≈113.09734
Volume of scoop: 113.1 cm^2
V=πr2h
3=π·2.52·10
3≈65.44985
Volume of cone: 65.45 cm^2
65.45 < 113.1
Answer:
5 and 50
Step-by-step explanation:
Constant of proportionality=(10-5)/(2-1)=5
Distance is 5*10=50
Answer:
Age of Eva = 15 Years
Age of Carrie = 45 Years
Step-by-step explanation:
Let the age of Eva be X years
Given that Carrie is 3 times as old as Eva
Therefore age of Carrie = 3X YEARS.
__________________________________________________________
After 15 years
Age of Eva = X + 15
Age of Carrie = 3X +15
Given that Carrie is twice as old as Eva
so according to this condition
age of Carrie = 2*Age of Eva
Substituting the age of Eva and Carrie
3X +15 = 2*(X + 15 )
=> 3X +15 = 2X +30
=> 3X - 2X = 30 - 15
=> X = 15
Since X was assumed age of Eva so age of Eva is 15 years
age of Carrie = 3X years = 3*15 = 45 years.
