Answer:
The balance in her lunch account at the end of the day on Friday is -$1.15.
Step-by-step explanation:
The balance at the end of the week will be the result of adding up the initial balance with the amount deposited on Monday minus the total amount spent that week.
Initial balance=$2.60
Amount deposited on Monday=$20
Total amount spent that week=$4.75*5=$23.75
Balance=$2.60+$20-$23.75
Balance=$22.60-$23.75
Balance=-$1.15
According to this, the answer is that the balance in her lunch account at the end of the day on Friday is -$1.15.
Answer:
Step-by-step explanation:
The common ratio is given as 2, so the base of any exponential must be 2 (not -2 or 2.25). The 4th term is negative, so the initial value must be negative (since the multiplying factor is positive). The only selection matching these requirements is d.
You know the general term is ...
... an = a1·r^(n-1)
so the 4th term is
... -18 = a1·2^(4-1) = 8·a1
Then the first term is ...
... a1 = -18/8 = -2.25 . . . . . confirms our choice of answer d.
The answer that is needed in the blank is disturbance
You can use a proportion.
4 hours is to 82 miles as 14 hours is to x miles
4/82 = 14/x
Cross multiply to get
4x = 14 * 82
4x = 1148
x = 287
287 miles
Answer:
A
Step-by-step explanation:
SA = πr² + πrs
r = 4.42
s = 2.61
SA = π(4.42)² + π(4.42)(2.61)
SA = 19.5364π + 11.5362π
SA = 61.34 + 36.22
SA = 97.56
The closest answer would be A.
Best of Luck!
