n=48.76
Step-by-step explanation:
Answer:
(d) a1 = 11
Step-by-step explanation:
Put the numbers in the given formula and solve for a1.
a5 = 176 = a1(r^(5-1)) = a1·r^4
a7 = 704 = a1(r^(7-1)) = a1·r^6
Dividing a7 by a5 gives ...
a7/a5 = (a1·r^6)/(a1·r^4) = r^2 = 704/176 = 4
Then a1 is ...
a1 = a5/(r^4) = 176/(r²)² = 176/(4²) = 11
The first term is 11.
Answer: Libby build 1.27 inches of fence each day .
Step-by-step explanation:
Since we have given that
Length of fencing built by Libby = 56 feet long
Number of days she needed = 44 days
According to question, the same length of fence each day is built by her.
We need to find the number of inches per day so, we will use "Division Rule ":
Number of inches of fence build each day is given by
Hence, Libby build 1.27 inches of fence each day .
The cost is $395. You are trying to find <em>n</em> in 24<em>n</em> + 35.
Set C = 395.
You get 395 = 24<em>n</em> + 35.
Solve for <em>n</em> by first subtracting 35 from both sides of the equation:
395 - 35 = 360.
24<em>n</em> + 35 - 35 = 24<em>n</em>.
Now you have 360 = 24<em>n</em>. Divide both sides by 24 to get:
15 = <em>n</em>.
So, 15 birthday cakes are made when the cost is $395.
The largest whole number that rounds to 2,500 when
rounded to the nearest 100 is 2,549 .
