6.928203230275509 is the exact answer but if you wanna round it to the nearest tenth its 6.9 and the nearest hundredth is 6.95
Answer:
b = T / $3
T = $3b
Step-by-step explanation:
Given that:
Cost per box of cereal = $3
Total amount from sale of cereal = T
Number of boxes sold = b
Number of boxes sold = (Total amount from sale of cereal / cost per box)
Number of boxes (b) = T / $3
T = $3b
Answer:
1/7 of a box of food.
Step-by-step explanation:
Rosie's leaving for SEVEN days, Spot can eat ONE box a week, if he eats the same amount every day, the answer would be 1/7.
The sqrt function has the distributive property.
So sqrt(a/b) = sqrt(a) / sqrt(b).
In this case, a = 81, and b = 625.
sqrt(81) = 9.
sqrt(625) = 25.
So sqrt(81/625) = 9 / 25.
To get a decimal representation, multiply by a form of 1 that makes the denominator a power of 10. Here, 25 * 4 = 100, so
9/25 * 4/4 = 36/100 = 0.36
Answer:
f(n)=-5-3n
Step-by-step explanation:
Given the recursive formula of a sequence
f(1)=−8
f(n)=f(n−1)−3
We are to determine an explicit formula for the sequence.
f(2)=f(2-1)-3
=f(1)-3
=-8-3
f(2)=-11
f(3)=f(3-1)-3
=f(2)-3
=-11-3
f(3)=-14
We write the first few terms of the sequence.
-8, -11, -14, ...
This is an arithmetic sequence where the:
First term, a= -8
Common difference, d=-11-(-8)=-11+8
d=-3
The nth term of an arithmetic sequence is determined using the formula:
T(n)=a+(n-1)d
Substituting the derived values, we have:
T(n)=-8-3(n-1)
=-8-3n+3
T(n)=-5-3n
Therefore, the explicit formula for f(n) can be written as:
f(n)=-5-3n
