Answer:

10% decrease

Step-by-step explanation:

The formula for percent change is:

\frac{\textrm{New}-\textrm{Old}}{\textrm{Old}} \times 100

Therefore, for this example:

\frac{\textrm{New}-\textrm{Old}}{\textrm{Old}} \times 100=\frac{135-150}{150} \times 100=-10\%

The negative value indicates that the change was a decrease. Therefore, there was a 10% decrease.

1 answer = 1 step closer to me getting to play animal crossing
OLEGan [10]

Answer:

The answer to your question is the letter A. 20 ft²

Step-by-step explanation:

Data

length of a side = 10 ft

length of the diameter = 10 ft

length of the radius = 5 ft

Process

1.- Calculate the area of the square

Area of the square = side x side

                                = 10 x 10

                                = 100 ft²

2.- Calculate the area of the circle

Area = πr²

Area of the circle = (3.14)(5)²

Area of the circle = 78.5 ft²

3.- Calculate the remaining area

Remaining area = 100 - 78.5

Remaining area = 21.5 ft²   ≈ 20 ft²

Allisa [31]

Answer:

6

Step-by-step explanation:

Sample space of the experiment

first number in the bracket is white die and second number in the bracket is black

(1,1) (1,2) (1,3) (1,4) (1,5) (1,6)

(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)

(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)

(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)

(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)

(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)

As it can be seen that the first numbers in the bracket are (1,1) (1,2) (1,3) (1,4) (1,5) (1,6)

∴1 on the white die can be obtained in 6 ways

Compound interest <br> Plz help!!!
liraira [26]

Answer:

a) A(t) = 17500(1.0053)^{12t}

b) The balance after 8 years will be of $29,069.

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

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

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

a)

Loan of $17,500 means that P = 17500

6.4% interest rate means that r = 0.064

Compounded monthly means that n = 12. So

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

A(t) = 17500(1 + \frac{0.064}{12})^{12t}

A(t) = 17500(1.0053)^{12t}

b)

This is A(8). Then

A(8) = 17500(1.0053)^{12*8} = 29069

The balance after 8 years will be of $29,069.
