If we assume that the house has 2 floors, we separately measure the area of the first area and second floors. The area of the house can be divided into rectangles. The area of each floor of the house is equal to the sum of the areas of the rectangles that make it up. The area of a rectangle is equal to the product of 2 of its perpendicular sides.As for the perimeter, to calculate it you need to add the length of each side.

Of course, the area and perimeter of the house are utilized to calculate how much it will cost to repair, for example.

Sam bought an electric iron as a price of 25 less than the original price if the original price of it is $2500 at what price did
wlad13 [49]

Answer:

$2475  or $1875

Step-by-step explanation:

Assuming the question meant to say $25 less than the original price, it would be $2475 because $2500-$25= $2475

However, if the question meant to say that Sam bought the iron for 25% less than the original price, it would be $1875 because 2500*0.25= $625

$2500-$625= $1875

1400 dollars is placed in an account with an annual interest rate of 5.5%. to the nearest year, how long will it take for the ac
olga_2 [115]

It will take 19 years and 6 months for the account value to reach 2900 dollars

Step-by-step explanation:

Given

Principal amount = 1400 dollars

Rate = 5.5 %

Final value = A = 2900

We have to find t

So,

The formula for simple interest is:

A = P(1+rt)

Putting values

2900 = 1400(1+0.055.t)\\\frac{2900}[1400} = 1+0.055t\\2.071 = 1+0.055t\\2.071-1=0.055t\\1.071 =0.055t

Dividing both sides by 0.055

\frac{0.055t}{0.055} = \frac{1.071}{0.055}\\t = 19.47\ years

Rounding off to nearest tenth

19.5 years

Hence,

It will take 19 years and 6 months for the account value to reach 2900 dollars

What is the average rate of change of the function over the interval x = 0 to x = 8?
Hatshy [7]

Answer:

if f(x) = 3x+4, the rate of change is 4.

if f(x) = 2x+7, the rate of change is 2.

Step-by-step explanation:

We know that the average rate of change over the interval x=0 to x=8 is:

(f(x2) - f(x1))/x2-x1

Where:

x2 = 8

x1 = 0

if f(x) = 3x+4

so f(8)=3(8)+4 = 28

f(0)=3(0)+4 = 4

Then: (f(x2) - f(x1))/x2-x1 = (28 - 4)/8-0 = 24/8 = 3

On the other hand, if f(x) = 2x+7

f(8) = 2(8)+7 = 23

f(0) = 2(0)+7 = 7

Then: (f(x2) - f(x1))/x2-x1 = Then: 23 - 7/8-0 = 16/8 = 2
