Since 25 feet = 1/2 an inch, we know that an inch = 50 feet. 600/50 = 12 and 1000/50 = 20 so the whole park is 12x20 inches on the scale drawing.
1 hour = 60 minutes
1 minute = 60 seconds.
Saturn: 10 hours 39 minutes and 24 seconds.
Convert hours to minutes: 10 hours x 60 minutes per hour = 600 minutes.
Convert seconds to minutes: 24 seconds / 60 seconds per minute = 0.4 minutes.
Total time for Saturn : 600 minutes + 39 minutes + 0.4 minutes = 639.4 minutes
Answer:
b(n) = -23 + 18n
Step-by-step explanation:
NOTE - This is an arithmetic sequence, so each number is increasing by addition. If you were in a geometric sequence, however, you'd be multiplying. This means that the explicit formula for the geometric sequence you'll be learning later on will be different.
The formula for explicit formula is b(n)=b(1)+d(n-1). The variable d represents the common difference and the a is whatever number of the term you are using.
Since you have b(1), you look at what your first term is. Plug -5 into a(1).
To find your common difference, find 13-(-5). This is 18, and adding it to the others you can see that it continues.
So, plugging in what you have so far it looks like b(n) = -5 + 18(n - 1)
All we need to do now is simplify.
1. Distribute: -5 + 18n - 18
2. Add like terms: -23 + 18n
Hope this helped and made sense lol.
I think you mean
so therefor since we can't take squaer root of negative
3t-9 must not be negative
basicaly, 3t-9 must be greater than or equal to 0
According to the given information, we build the equation for the cost. After we build the equation, the equation that relates these measures is:
Cost:
0.3 kilograms of tomatoes, at 3.30 dollars per kilogram.
Thus, the cost starts at:
y kilograms of cucumbers, at x dollars per kilogram.
Considering this, the cost will now be of:
0.2 kilograms of carrots, at z dollars per kilogram:
Now, we have to consider this for the cost, so:
