Answer:
see the explanation
Step-by-step explanation:
we know that
An extended ratio compares three or more numbers.
In the extended ratio a:b:c
The ratio of the first two numbers is a:b (you can write a to b or a/b)
The ratio of the last two numbers is b:c (you can write b to c or b/c)
The ratio of the first and last numbers are a:c (you can write a to c or a/c)
Okie doke. So, we are rounding this number to the nearest thousandths place, which is three digits behind the decimal. The rules for rounding are if the number is 5 or more in the digit behind it, the number goes up. If it is 4 or less, the number goes back. In other words, we depend on the digit right of the digit we are rounding to in order to see what we do. The number we are rounding is 1.49882. The 8 is in the thousandths place and the 8 is to the right of that, which is the ten thousandths place. Because 8 is greater than 5, the number rounds up. So the number rounded to the nearest thousandth is 1.500.
Answer:
V = 2010.6193m^3
Step-by-step explanation:
This is right assuming 8m is the radius and 10m is the height
If his speed is 43 mph, then it takes him 40/43 of an hour to go 40 miles.
An hour = 60 minutes.
40/43 of 60 minutes = 55.8 minutes. He gets home 55.8 minutes after 6:24 PM.
72 total pupils
8x passed the test, x did not
8x + x = 72
9x = 72
x = 8
So since 8x passed the test, substitute 8 for x
8(8) = 64
64 pupils passed the exam
