Answer:
B
Step-by-step explanation:
V = (4 * pi /3) * (38 + 0.16t)^3
t = 208 seconds.
V = (12.56/3) * (38 + 0.16 * 280)^3
V = 4.186 * ( 38 + 44.8)^3
V = 4.286 * (82.8)^3
V = 4.286 * 567663
V = 2433005 which is close enough. The precise answer will be obtained by using a better value for pi. Anyway that's the only answer that gives about 2.5 million so B is correct.
Answer:
Step-by-step explanation:
Here is the complete question: 28 elementary schools to 16 middle schools, write the ratio in simplest form.
Given ratio= elementary schools: middle schools:: 28:16
The ratio can be written as
Now to write into simplest form, we need to divide both numerator and denominator by 4.
∴ elementary schools: middle schools=
Hence, we get simplest ratio of elementary schools to middle schools=
-8 you have to do a number line
Answer:
