Closing parenthesis is misplaced. Should be:
<span>A = h(b₁ + b₂)/2 </span>
<span>h = 75 ft </span>
<span>b₁ = 125 ft </span>
<span>b₂ = 81 ft </span>
<span>Then it's just plug & grind: </span>
<span>A = 75(125 + 81)/2 ft² = 75·206/2 ft² = 75·103 ft² = (7500 + 225) ft² = 7725 ft² </span>
<span>If you follow that, it will guide you through any other, similar p</span>
Answer:
216x⁶y⁹
Step-by-step explanation:
[(3x²y³)2]³
[6x²y³]³
[6]³.[x²]³.[y³]³
216.x⁶.y⁹
216x⁶y⁹
First convert everything into inches.
1 foot = 12 in
5 feet = 5*12 = 60 in
12 feet = 12*12 = 144 in
Now add them together
60 + 9 + 144 + 3 = 216 in
or
18 feet
Hope this helps :)
Answer:
-1
Step-by-step explanation:
The mean is the sum of all values divided by the amount of values.
We take the sum of all the numbers:
-3 + -8 + 12 + -15 + 9
-11 + 12 + -15 + 9
1 + -15 + 9
10 + -15
-5
We then divide the sum by how many number we have (we are given 5 numbers):
-5/5 = -1
Therefore, our mean is equal to -1.
B because 2 and 1/3 is 7/3 as an improper fraction times 4 is 28/3 and as a mixed number it is 9 and 1/3
