Answer:
X=7 1/3, y=0
Step-by-step explanation:
1) 1.5x+2y=11 --> 3x+4y=22
2) 3x+6y=22
Subtract 1) from 2)
2y=0
y=0
Plug into 2)
3x+6*0=22
3x=22
x=7 1/3
Answer:
the 3rd One!
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
1. You have the following logarithm:
<span>log(2)n=4
2. Therefore, you con rewrite it as below:
loga(b)=logb/loa
</span>
3. Therefore, you have:
log(2)n=4⇒log(n)/log(2)=4
4. Then, you obtain:
log(n)=4log(2)
5. Therefore, as you can see, the answer for the exercise shown above is the last option, which is:
log(n)=4log(2)
Drop the 4 down to make it equal to 2.
Answer:
Volume = 3,689,616 m³
Step-by-step explanation:
A large office building would make a three-dimensional shape of a rectangular prism. The formula for the volume of a rectangular prism is:
V =lwh, where l = length, w = width and h = height
In this case, the l = 158m; w = 56m and h = 417m. Putting these values into the formula for volume:
V= (158)(56)(417) = 3,689,616 m³
