Answer:
1. 64
2. 72 square feet
3. 31.5 square feet
Step-by-step explanation:
For the first one use the equation A=bh.
Plug in your values: A=12.8*5.
Solve: A=64
For the second one multiply 8*3 which gives you 24. Next multiply that by 3 to give you 72 square feet.
For the third one multiply 9 by 3.5 to get 31.5 square feet.
Answer:
<em>76 degrees</em>
Step-by-step explanation:
The corresponding angles help you solve this.
The vertical angle of x (meaning the one practically in front of it) is 76 degrees, since x is vertical to 76, the degree will be the same.
Divide 9/40 will give you 0.225
Multiply it by 100
= 0.225 x 100 = 22.5%
Answer:
The answer is
<h2>
![{8.y}^{12}](https://tex.z-dn.net/?f=%20%7B8.y%7D%5E%7B12%7D%20)
</h2>
Step-by-step explanation:
(2y⁴)³
Using the rules of indices
That's
<h3>
![( {ax})^{b} = {a}^{b} . {x}^{b}](https://tex.z-dn.net/?f=%28%20%7Bax%7D%29%5E%7Bb%7D%20%20%3D%20%20%7Ba%7D%5E%7Bb%7D%20.%20%7Bx%7D%5E%7Bb%7D%20)
</h3>
So for the above expression we have
<h3>
![( {2y^{4} })^{3} = {2}^{3} . {y}^{4 \times 3}](https://tex.z-dn.net/?f=%28%20%7B2y%5E%7B4%7D%20%7D%29%5E%7B3%7D%20%20%3D%20%20%7B2%7D%5E%7B3%7D%20.%20%7By%7D%5E%7B4%20%5Ctimes%203%7D%20)
</h3>
Simplify
We have the final answer as
<h2>8.y¹²</h2>
