Answer:
Mary's sister is 12 years old.
Step-by-step explanation:
If Mary is half of her sister's age, her sister is 2 times her age.
Represent M as Mary's age...
M+2m=18
3m=18
3m/3=18/3
m=6
But because Mary is a half of her sister's age...
6*2=12

Answer:
167.6 cm³
Step-by-step explanation:
the volume of a cone :
ground area × height / 3 = pi×r² × height / 3
r = 4 cm
height = 10 cm
pi×4² × 10 / 3 = pi×16×10/3 = pi×160/3 = 167.6 cm³
For this case we can make the following rule of three:
1 box -------------> 15 paperweights
x -------------------> 1269 paperweights
We clear the value of x.
We have then:
x = (1269/15) * (1)
x = 84.6
Rounding to the nearest whole:
x = 85
Answer:
There will be needed about:
x = 85 boxes
