Answer:
Average = 96
Step-by-step explanation:
Average = sum of terms/ number of terms
sum of terms = number of burgers sold
number of terms = number of visitors
d = number of days since Monday which is 7
burgers sold = 200d^3 + 542d^2 + 179d + 1605 substituting d with 7
burgers sold = 200(7)³ +542(7)² + 179(7) +1605
burgers sold =68600 + 26558 + 1253 + 1605
burgers sold =98016
number of visitors= 100d + 321
number of visitors= 100(7) + 321
number of visitors= 700+321
number of visitors= 1021
Average = 98016/1021
Average = 96
Do the problem 440×7.5 to find your answer
They will have same amount in 45 weeks.
Step-by-step explanation:
Given,
Starting amount of Nancy = $425
Per week saving = $25
Let,
x represent the number of weeks.
N(x) = 25x+425
Starting amount of Seamus = $875
Per week saving = $15
S(x) = 15x+875
For same amount;
N(x) = S(x)

Dividing both sides by 10

They will have same amount in 45 weeks.

Answer:
50ft
Step-by-step explanation:
Hi,
Considering that one side is equal to 38 degrees, we know this isn't a 30 - 60 - 90 triangle.
One of the legs is equal to 40 feet
So, tan(b) = 40/x
tan(38 degrees) is 0.78 round up to 0.8 (if that's what your teacher wants)
0.8 = 40/x
0.8x = 40
x = 50ft
I hope this helps
