Naddik [55]

Answer:

100 rupee notes= 6, 50 rupee notes=3

Step-by-step explanation:

3 x 50 = 150

6 x 100 = 600

600 + 150 = 750

the algebraic expression 6(2x)+9x+3 represents the area of a rectangle .what is the the area of the rectangle when x =3 feet

sashaice [31]

Answer:

66. Assuming after you substituted 3 in place of x, you followed order of operations, or PEMDAS.

Step-by-step explanation:

6(2x) + 9x +3 = area

6 (2(3)) + 9(3) + 3 = area

6 x 6 + 27 + 3 = area

36 + 30 = 66

area = 66

A principal of $6000 is invested in an account paying an annual rate of 5%. Find the amount in the account after 4 years if th

astra-53 [7]

Solution :

Given :

Principal amount deposited, P = $ 6000

Rate of interest, r = 5%

Number of years, t = 4 years

When the deposited amount is compounded semiannually, i.e. n = 2

Therefore,

Future value,

$FV = P\left( 1 +\frac{r}{n}\right)^{nt}$

$FV = 6000\left( 1 +\frac{0.05}{2}\right)^{2 \times 4}$

$FV = 6000 \times (1.025)^8$

= 6000 x 1.2184

= 7310.4

Therefore, after 4 years there will be $ 7310.4 in the amount when compounded semi annually.

When the deposited amount is compounded quarterly, i.e. n = 4

Therefore,

Future value,

$FV = P\left( 1 +\frac{r}{n}\right)^{nt}$

$FV = 6000\left( 1 +\frac{0.05}{4}\right)^{4 \times 4}$

$FV = 6000 \times (1.0125)^{16}$

= 6000 x 1.219889

= 7319.334

Therefore, after 4 years there will be $ 7319.334 in the amount when compounded quarterly.

When the deposited amount is compounded monthly, i.e. n = 12

Therefore,

Future value,

$FV = P\left( 1 +\frac{r}{n}\right)^{nt}$

$FV = 6000\left( 1 +\frac{0.05}{12}\right)^{12 \times 4}$

$FV = 6000 \times (1.0041667)^{48}$

= 6000 x 1.22089

= 7325.34

Therefore, after 4 years there will be $ 7325.34 in the amount when compounded monthly.

Solve for rv=r+at, for r

mafiozo [28]

$v=r+at$

Since we need to solve for r we have to leave that variable alone in one side of the equation. We notice that at is adding in the right side, then it goes to the left side substracting, that is:

$v-at=r$

Therefore:

$r=v-at$

in the last part we only switch the sides of the equation.
