Summer has an offer to buy an item with a sticker price of $13,200 by paying $460 a month for 36 months. What interest rate is S
AysviL [449]

Answer:

the annual interest rate is 7.583%

Step-by-step explanation:

We are given

Summer has an offer to buy an item with a sticker price of $13,200

so, we have

P=13200

paying $460 a month for 36 months

so, we can find total amount

A=460\times 36

A=16560

Let's assume

annual interest is r

total time =36 months

so, total number of years =3

Since, it is compounded monthly

so, n=12

now, we can use formula

A=P(1+\frac{r}{n} )^{nt}

now, we can plug values

16560=13200(1+\frac{r}{12} )^{36}

now, we can solve solve for r

(1+\frac{r}{12} )^{36}=\frac{16560}{13200}

r=0.07583

So, the annual interest rate is 7.583%

Pepsi [2]
Because the account PAYS compound interest per year it's called depreciation.
So you do 100-3.4 = 96.6, the divide by 100 = 0.966
Then you do 0.966^3 x £6000 = £5408.6

From the diagram below, if AD = 5, and DB = 10, what is the length of CD? ​
bazaltina [42]

Answer:

20

Step-by-step explanation:

According to Euclidian theorem:

h^2 = AD*CD (h is the height, DB in this case)

rewrite the equation by using given values

10^2 = 5*CD find the square value of 10

100 = 5*CD divide both sides by 5

20 = CD
