First break it up into 3 different rectangles based on what you know. Since you can make two big 4*8 rectangles, do so first.
2(4*8)=64
The middle rectangle comes next. You can figure out that height by subtracting the 3s from the total 8. So the height = 8-(3+3) = 2.
2*4=8
64+8= 72
Answer:
um heyz.
Step-by-step explanation:
please follow me and give me a thanks because im new user in brainly pleease and mark me as brainliest.
First of all, your sample equation is wrong, it is y=mx+b, not y=mx+c, but anyway, the finished equation is going to be y=3, hope this helps
The model given is:
The term in the parentheses represents the change of rate of the model. If the number is the parentheses is less than 1, we call it <em>exponential decay</em>.
If the number in parentheses is bigger than 1, we call it exponential growth.
In this case, the correct option is "decaying"
The number in parentheses let's call it R, is:
Where r is the rate of change. To find it:
To convert to percentage, we convert by multiplying by 100::
The second answer is 0.45%
And since t is the time passed in hours, and has a "60" multiplying it, the last answer is: Every 60 hours
<em>The final answer is:</em>
The function is exponentially decaying at a rate of 0.45% evary 60 hours.
Well the volume of dirt she needs to remove is equal to length*width*height=6.2*4.9*0.225=6.8355
Now let's find how many bags she needs.
To solve for this, simply divide room in bags from total room.
6.8355/0.87=7.857
Thus Zoe has barely enough, but enough bags.
