Area of a trapezoid = h/2 ( a + b) where h = height and a and b are the lengths of the 2 parallel sides.
So here we have
Area = 12/2 ( 18 + 23)
= 246 in^2 Answer
ii . volume of a sphere = 4/3 pi r^3 so
1436.03 = 4/3 pi r^3
r^3 = 1436.03 / (4/3 * pi) = 342.827
r = cube root of 342.827 = 7.0 m Answer
Answer:
Okay so what we need to do is prove that they are not the same.
Step-by-step explanation:
So first we need to find out what 6*2 is which practically is 6 x 6.
Its so because the exponent 2 means you multiply that by that many times. So it would look like 6 x 6 which is different from 2 x 6.
2 x 6 is just multiplying the two different numbers together, and they are not expenentiol so that's your answer.
Hope this helped :P
Answer: Joe's weekly allowance = $12
Step-by-step explanation:
Joe spent half of his weekly allowance playing mini-golf
Let a = his weekly allowance
This means Joe spent a/2 playing mini-golf.
To earn money, his parents let him weed the garden for $6
This means Joe's total money
= a + 6
What is his weekly allowance if he ended with $12?
This means he had $12 left after spending a/2 from ta total of (a +6)
Therefore,
(a +6) -a/2 = 12
Taking LCM of 2
[2(a+6)-a]/2=12
Cross multiplying by 2
2a + 12-a = 24
a+12 =24
a = 24-12 =$12
Joe's weekly allowance = $12

Answer: No, it is not a solution
Work Shown:
-2 ≤ k/3
-2 ≤ -9/3
-2 ≤ -3
The last inequality is false because -3 should be smaller than -2 (not the other way around). Use a number line to help see this.
Since the last inequality is false, the original inequality must also be false for that particular k value. Therefore, k = -9 is not a solution.
