tino4ka555 [31]

Answer:

103 degrees

Step-by-step explanation:

The sum of the measures of all triangles is 180 degrees. The two angles given total 77 degrees. Subtracting 77 from 180 leaves 103 degrees for the 3rd angle

22.11 divided by 11?

Dimas [21]

Answer: 2.01

Explanation: I rounded 22.11 two 22. So when you divide it by eleven is 2. Then you divide 11 by 11. Which is one, and it seems it was in the hundreths place so you add a cero before the one.

11. Mr Lee bought a second hand car for

Marrrta [24]

Answer :

Depends on the rate compound interest is accrued. See answers.

Step-by-step explanation:

We need the compound interest formula which is:

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

A = final amount

P = initial principal balance

r = interest rate

n = number of times interest applied per time period

t = number of time periods elapsed

It doesn't say how frequently the interest is compounded, so we will do monthly, quarterly, and yearly.

MONTHLY

So we know the car costs $25,480 and he made a down payment of $10,000. By subtracting the down payment from the purchase price we find the loan amount.

$25,480 - $10,000 = $15,480

P = 15,480

r = 4.75% = .0475

n = 12 (12 months in a year)

t = 2

Plug everything into the compound interest formula.

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

$A = 15480(1+\frac{.0475}{12})^{12*2}$

$A = 15480(1+\frac{.0475}{12})^{24}$

$A = 15480(1+.00396)^{24}$

$A = 15480(1.00396)^{24}$

$A = 15480*1.0992$

$A = $17016.14$

Mr. Lee paid $17,016.14 when the bill came due at 2 years with interest compounded monthly.

QUARTERLY

P = 15,480

r = 4.75% = .0475

n = 4 (4 quarters in a year)

t = 2

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

$A = 15480(1+\frac{.0475}{4})^{4*2}$

$A = 15480(1+\frac{.0475}{4})^{8}$

$A = 15480(1+.0119})^{8}$

$A = 15480(1.0119)^{8}$

$A = 15480*1.099$

$A = 15480(1.099)$

$A = 17013.20$

Mr. Lee paid $17,013.20 when the bill came due at 2 years with interest compounded quarterly.

YEARLY

P = 15,480

r = 4.75% = .0475

n = 1

t = 2

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

$A = 15480(1+\frac{.0475}{1})^{1*2}$

$A = 15480(1+\frac{.0475}{12})^{2}$

$A = 15480(1+.0475})^{2}$

$A = 15480(1.0475)^{2}$

$A = 15480*1.0973$

$A = 16985.53$

Mr. Lee paid $16,985.53 when the bill came due at 2 years with interest compounded yearly.

To mail a package, the rate is x cents for the first pound and y cents for each additional pound, where x>y. Two packages wei

horrorfan [7]

Answer:

Option A) Combined, with a saving of x-y cents

Step-by-step explanation:

We are given the following in the question:

The rate to mail a package is x cents for first pound and y cents for each additional pound.

$x>y$

Weights of packages =

3 pounds and 5 pounds

Cost of combined package:

Total weight = 8 pounds

$C\text{(combined)} = x + 7y$

Cost of sending separately:

$C\text{(separated)} = (x + 2y) + (x + 4y) = 2x + 6y$

Difference between cost of sending the packages separately and combined

$C\text{(separated)}-C\text{(combined)} \\=2x + 6y-(x+7y)\\=(x-y)\text{ cents}$

Thus, sending the packages combined is a cheaper method with a saving of (x-y) cents

Thus, the correct answer is:

Option A) Combined, with a saving of (x-y) cents
