a. The formula solved for t is t = I/Pr 
b. The value of t in the table is 3 years 
<h3>Simple Interest</h3>
From the question, we are to solve for t in the given formula
The given formula is the formula for simple interest 
I = Prt 
To solve for t, we will divide both sides of the equation by Pr
That is, 
I/Pr = Prt/Pr 
I/Pr = t 
∴ t = I/Pr
The formula solved for t is t = I/Pr 
b. We are to find the value of t when 
I = $75 
P = $500 
r = 5% = 0.05
From 
t = I/Pr 
t = 75/(500×0.05)
t = 75/25
t = 3 years
Hence, the value of t in the table is 3 years

Answer: 2908.92435 inches.
Step-by-step explanation for shape 1: A = 2(wl + hl + hw) = 2 · (30 · 13 + 13 · 13 + 13 · 30) = 1,898 inches.
Step-by-step explanation for shape 2:
Using the formulas:
A=2AB+(a+b+c)h
AB=s(s﹣a)(s﹣b)(s﹣c)
s=a+b+c
2
Solving for A:
A=ah+bh+ch+1
2﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=9·30+13·30+9·30+1
2·﹣94+2·(9·13)2+2·(9·9)2﹣134+2·(13·9)2﹣94≈1010.92435
Step-by-step explanation for total volume: 2908.92435 inches.
 
        
                    
             
        
        
        
Hi there!
First we subtract 44-14 leaving us with 30. 5x6 = 30 
Therefore, a member can visit a history museum 6 times to equal a total cost of $44.
In a different situation:
If the person has already paid the $14, and that doesn’t count as a visit, then a person would have to visit a museum 8 times to get a total of $45. Considering this is a real-world problem. 
I hope this helps and have a good day :) !

Answer:
11 bottles
Step-by-step explanation:
make a proportion because if you're using the same rate proportions can show that it's equal

cross multiply


divide the answer by 90 to find x

round to 11 because you can't have 10.8 bottles
 
        
             
        
        
        
Answer:
$4.84
Step-by-step explanation:
County A: Multiply the price by the sales tax to find out how much money the sales tax will add. Remember to convert percent to decimal!
$75 * 0.0725 = $5.4375
Add the original price and the sales tax.
$75 + $5.4375 = $80.4375
County B: Multiply the price by the sales tax to find out how much money the sales tax will add. Remember to convert percent to decimal!
$70 * 0.08 = $5.6
Add the original price and the sales tax.
$70 + $5.6 = $75.6
Then take the difference.
80.4375 – 75.6 = 4.8375
Round to the nearest hundredth: $4.84
