At what rate of interest would rs 1800 amount to rs 2500 in 2 years

Romashka [77]

Interest formula: A = P(1 + rt)

Solving for r (Rate): r = (1/t)(A/P - 1)

Rate = (1/2)(2500/1800 - 1) = (1/2)(25/18 - 1) = (1/2)(7/18) = 7/36 ≈ 0.194

Rate = 0.194% per annum

Order the following numbers from least to greatest.

zaharov [31]

Answer:

-5.5 $-\sqrt{20}$ $\sqrt4$ $\frac{22}{7}$ 4.5

Step-by-step explanation:

Given:

The numbers to order from least to greatest is given as:

$-5.5, 4.5, 22/7,\sqrt4,-\sqrt{20}$

In order to compare these numbers, we have to convert them in same form.

Let us simplify each number in decimal form.

$-5.5 = -5.5\\\\4.5=4.5\\\\\frac{22}{7}=3.14\\\\\sqrt4=2\\\\-\sqrt{20}=-\sqrt{5\times 2^2}=-2\sqrt5=-4.47$

So, the least number is one which has the largest value with a negative sign.

Here, -5.5 is the least number.

The next smallest number is -4.47. So, $-\sqrt{20}$

The next smallest number is 2. So, $\sqrt4$

The next smallest number is 3.14. So, $\frac{22}{7}$

The greatest number is 4.5.

Therefore, the order from the least to greatest is:

-5.5 < $-\sqrt{20}$ < $\sqrt4$ < $\frac{22}{7}$ < 4.5

Area = 120 units squared <br> Base = 8 units <br> Length = ? (Include the units in your answer)

Vesnalui [34]

Answer:

Step-by-step explanation:

Okay, so we know that Base*Length=Area, so we just have to divide the area by the base, so the formula here is Area/Base=Length.

That would get us 120/8=Length,

and if we just divide 120 by 8 we get 15, so the length is 15
