Answer:
60%
Step-by-step explanation:
If I get you right, you're asking for the percentage gain to the nearest percentage, right?
Now to do this, we need to get the amount of profit she made. That's quite easy, we only need to subtract the cost price from the selling price. And that equals $15 - $9.38 that equals $5.62.
Now, we divide this value by the cost price and multiply by 100% to get the percentage gain.
I.e 5.62/9.38 × 100%.
That gives 59.9% , which equals 60% when approximated to the nearest percentage.
Answer:
f(- 5) = 13
Step-by-step explanation:
Substitute x = - 5 into f(x)
f(x) = - 3x - 2 , then
f(- 5) = - 3(- 5) - 2 = 15 - 2 = 13
Answer:
y = 30(2)^x
Step-by-step explanation:
Initial deer population = 30 (in 2010)
Every year, deer population doubles ; this means there is an 100% increase in the population every year ;
Hence, using the exponential growth relation :
Final = initial * (1 + rate)^year
Here,
Final population y ; x years after 2010
Rate = 100% = 1
Hence,
y = 30(1 + 1)^x
y = 30(2)^x
Answer:
120
Step-by-step explanation:
.
Plug in the information given:
.
Now we want to solve this equation for Run.
If you don't like Run as a variable, let's just use x in it's place:
Cross multiply:
Simplify both sides:
The run is 120.
Let's check our work.
.
So if our rise is 6 and our run is 120.
Does 6/120 reduce to 1/20?
6 and 120 do have a common factor of 6.
So if you divide top and bottom of 6/120 by 6 you do get 1/20.
3 because a polygon has 3 or more sides
