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.

Based on the information, it should be noted that the value of x is 3 and the measure of angle HEB will be 27°.

<h3>How to illustrate the information?</h3>

It should be noted that complementary angles are the angles that are equal to 90°.

Therefore, based on the information given, the expression will be illustrated thus:

19x + 6 + 9x = 90°

Collect like terms

28x = 90° - 6°

28x = 84

Divide through by 28

28x / 28 = 84/28

x = 3

Therefore, the value of HEB will be:

= 9x

= 9 × 3

= 27°

Therefore, based on the information, it should be noted that the value of x is 3 and the measure of angle HEB will be 27°.

Which radical expression is an irrational number? A. √ 121 B. √ 65 C. √ 36 D. √ 64
alina1380 [7]

We will verify each options

option-A:

\sqrt{121}

we can factor it

\sqrt{121}=\sqrt{11*11}

\sqrt{121}=\sqrt{11^2}

\sqrt{121}=11

so, this is not irrational.........Answer

option-B:

\sqrt{65}

Since, it can not be factored

so, this is irrational.........................Answer

option-C:

\sqrt{36}

we can factor it

\sqrt{36}=\sqrt{6*6}

\sqrt{36}=\sqrt{6^2}

\sqrt{36}=6

so, this is not irrational.........Answer

option-D:

\sqrt{64}

we can factor it

\sqrt{64}=\sqrt{8*8}

\sqrt{64}=\sqrt{8^2}

\sqrt{64}=8

so, this is not irrational.........Answer
