vekshin1

Answer:

₹2520

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 10%/100 = 0.1 per year,

then, solving our equation

I = 12600 × 0.1 × 2 = 2520

I = ₹ 2,520.00

The simple interest accumulated

on a principal of ₹ 12,600.00

at a rate of 10% per year

for 2 years is ₹ 2,520.00.

Two complementary angles are represented by x and x+14 . find the value of x

qaws [65]

Answer:

$x=38\textdegree$

Step-by-step explanation:

Remember that complementary angles <em>always </em>add up to 90°.

We know that the two complementary angles are represented by (x) and (x+14). In other words:

$(x)+(x+14)=90$

So, let's solve for x.

First, combine like terms:

$2x+14=90$

Let's isolate the x by subtracting 14 from both sides:

$(2x+14)-14=(90)-14$

The left cancels. Subtract on the right:

$2x=76$

Divide both sides by 2:

$\frac{2x}{2}=\frac{76}{2}$

The left side cancels. Divide on the right:

$x=38\textdegree$

So, the value of x is 38°.

And we're done!

x = length of one side.

1,232in^2 = x^2

Take the sqrt of both sides.

35.1 in = x

The length of one side = 35.1 in

A coin is flipped 25 times. How many ways can we get exactly 19 heads?

Fittoniya [83]

Answer:

177,100 ways

Step-by-step explanation:

"If you number the flips 1 through 25, then each different combination of 19 heads from the 25 total is considered different. So 25C19 = 25C6 is the number of distinct U Tube videos you could watch to yield your outcome. So it is 177,100 ways."
