Answer:
The answer is b (50.24)
step-by-step explanation:
A=πr2=π·42≈50.26548
7.2x10^-3--->.0072
you take 7.2 and move the decimal point 3 places to the left
1. Now let's first see what this would be added together.
1.5 + 3 + 4 = 8.5
And multiplied:
1.5 * 3 * 4 = 18
So basically, here, we can multiply by a decimal to decrease the multiply and increase the add, because if we increased the number, the multiplication would increase at a much larger scale.
So here, let's see what 18 * .5 is.
It's 9.
And 8.5 + 0.5 is 9.
So the fourth item was priced at 50 cents.
3. So if Deion Sander's 60 yard-dash time of 5.6 seconds was three times faster then Larry Lewis', we can first convert 60 yards to 100 yards.
It's 10/6 times more.
So we can just multiply 5.6 by 10/6.
5.6 * 10/6 = 56/6 = 28/3
Now since it's three times slower then that,
28/3 * 3 = 28
So he ran the 100 yard dash in 28 seconds.
To solve this problem, we have to substitute in the value of -6 for each x in the expression. This is shown below:
(x² - 3)/(x+3) = ((-6)² - 3)/((-6) + 3)
To simplify this seemingly daunting expression, we should first simplify the exponents in the numerator. This is because of the order of operations, outlined by PEMDAS, which states that we should compute numbers in parentheses first, exponents next, then multiplication and division, and finally addition and subtraction.
((-6)² - 3)/((-6) + 3) = (36-3)/(-6+3)
Now, we can perform the addition and subtraction in the numerator and denominator because they are both in parentheses.
(36-3)/(-6+3) = 33/-3
Finally, we can perform the last operation of division.
-11
Therefore, your answer is -11.
Hope this helps!
