10,000,000+2,000,000+400,000+30,000
Answer:
the answer is c
Step-by-step explanation:
x and y have to be at least 12, so that's why the greater than sign was used
the amount of money had to be at most $230, so that's why the less than sign was used
they said x and y represent black and white respectively, so that means x is black and y is white, so it is 18x and 20y
Answer:
tha answer is leter C thanks po
Step-by-step explanation:
thanks you po ??
The formula for volume of a sphere is (4/3)πr², with r being the radius. Since the diameter of the sphere is 18 cm, the radius is 18/2, which is 9. Now substitute the 9 for r so you have:
V=(4/3)π*9²
V=(4/3)π*81
V=108π
108π is the exact volume of the sphere.
