Answer:
224
Step-by-step explanation:13/x8=28 so 28X8=224
In the question , the length of the actual rope is given as 40 foot. Also it is given that the length of one rope after cutting the original piece of rope into 2 pieces is 9 times that of the other pice.
Let us assume that the length of one piece of rope is = X
Then the length of the orther pice of rope = 9X
Now we can easily get the equation
X + 9X = 40
10X = 40
X = 40/10
X = 4
So the length of the shorter rope is 4 foot.
The length of the longer rope is 9 times that of the shorter one.
So the length of the longer rope is 36 foot.
The amortization formula can be used to figure this.
... A = P(r/n)/(1 -(1 +r/n)^(-nt))
where A is the monthly payment, P is the amount borrowed, r is the annual interest rate, n is the number of times per year interest is compounded, and t is the number of years.
Fill in the given information, and solve for P (in either order).
... 821.69 = P(.065/12)/(1 - (1 +.065/12)^(-12*30)) ≈ 0.00632068023P
... P ≈ 130,000.25 . . . . . divide by the coefficient of P
Rounded to the nearest dollar, you borrowed $130,000.
The total cost of the bracelet will be $96.
The number of charms will be 2.
Step-by-step explanation:
Given,
Cost per charm at Dayton Fine Jewelry = $17
Cost of bracelet = $62
Let,
x be the number of charms
y be the total cost
y = 17x+62 Eqn 1
Cost per charm at Cain Jewelers = $18
Cost of bracelet = $60
y = 18x+60 Eqn 2
For same cost;
Eqn 1 = Eqn 2
Putting x=2 in Eqn 1
Putting x=2 in Eqn 2
The total cost of the bracelet will be $96.
The number of charms will be 2.
