Answer:
V ≈ 68.63 cm³
Step-by-step explanation:
the volume (V) of a sphere is calculated as
V = 
πr³
the volume of a hemisphere is half the volume of a sphere, so
V = 
× πr³ = 
πr³ , then
V = π × 3.2³
= π × 32.768
≈ 68.63 cm³ ( to 2 dec. places )
14/4 is a fraction greater than 1.
Answer:
v=0.79x+3.99
f=1.89x+5.49
combined cost: 2.68×+9.48
Answer:
5y + 3x + 9
Step-by-step explanation:
Whenever something is multiplied by the same variable, you can combine the coefficients. In this case, first you'd move the values with the same variable next to each other, for simplicity:
7y-2y+3x+3+6
Then, combine like terms.
5y+3x+3+6
5y+3x+9
Answer:
Step-by-step explanation:
There are six sides on the die...
1, 2, 3, 4, 5, 6
Greater than or equal to 3 includes 3, 4, 5, 6
This means 4 out of 6, or 4/6
4/6 simplified is 2/3
Hope this helps!
