Answer:
The variable
Step-by-step explanation:
In order to solve the problem above, represent the width by x. With this, the length of the rectangular portrait is 1.5x. The perimeter of the rectangle is two times the sum of the length and width. This translates to,
2 (1.5x + x) = 10 ft, x = 2 ft.
Thus, the length of the rectangular portrait is 3 ft.
Complete question is;
If Pablo invests $4200 for 3 years and earns $630
A) what is the simple interest rate?
B) Pablo’s goal is to have $5000 after 4 years. Is it possible with a rate of 6%? Explain.
Answer:
A) Rate = 5%
B) Yes, it is possible for him to earn $5000 after 4 years with an interest rate of 6%
Step-by-step explanation:
A) Formula for interest is;
i = PRT
We are given;
i = 630
P = 4200
T = 3
Making R the subject;
R = i/PT
R = 630/(4200 × 3)
R = 0.05
This is 5%
B) Formula for value of principal after interest period is;
A = P(1 + RT)
P = 4200
R = 6% = 0.06
T = 4 years
Thus;
A = 4200(1 + (0.06 × 4))
A = $5208
Thus, it is possible for him to earn $5000 after 4 years with an interest rate of 6%
Answer:
15
Step-by-step explanation:
Answer:
$3.63
Step-by-step explanation:
A 10-minute call to France cost $3.19.
A 15-minute call to France costs $4.29.
Now we will use two point slope form
Substitute the values :
y is the cost and x is the number of minutes
Now we are suppose to find cost of a 12-minute call to France
Substitute x = 12
Hence the cost of a 12-minute call to France is $3.63
