Answer:
A
Step-by-step explanation:
You can tell that the equal share is more than 1 whole when the numerator is greater than the denominator.How? As we all know that in order to convert a fraction to a decimal number, we need to divide the numerator by the denominator.Now, if the numerator is less than the denominator, expect that the digit is now less than 1 whole. But if the numerator is greater than the denominator, for sure, it is more than 1 whole for example.=> 5/4 , where 5 is the numerator and 4 is the denominator<span>=> 1 and 1/4 or 1.25</span>
-- Ignore the signs and multiply the numbers.
-- If the original two numbers have the same sign, then the product is positive.
-- If the original two numbers have different signs, then the product is negative.
Answer:
-2
Step-by-step explanation:
9w-36-7w=15w-10
2w-36=15w-10
-13w=26
w=26/(-13)
w=-2
Answer:a) 84π b) 109.2π
Step-by-step explanation:
The formula to find this is v=πr^2h/3
r=d/2. so the radius (r) is 6 because you have to divide the diameter (12) by 2. and the height is 7. so, 6^2=36 and 36x7=252.
252/3=84
and because the question is asking for the EXACT value, you need to just put the pi symbol next to it. Final answer for a is 84π
B) you need to find 30% of 84, which is 25.2 and add it to 84, and you will get 109.2! Final answer is 109.2π.
