Katyanochek1 [597]3 years ago
5 0

Step-by-step explanation:

{2.71 \times 10}^{ - 3}

This can be rewritten as

2.71 \times  \frac{1}{10^{3} }

If we will solve this way,

\frac{2.71}{1000}  = 0.00271

But since the denominator is just in terms of 1, we can just simply get the (-3). Note that we have to take the negative into consideration.

From the original position of the decimal point, move the decimal point 3 times TO THE LEFT. Therefore, from 2.71 we move the decimal point 3 times to the left, 0.00271.

If the exponent has a positive value, move TO THE RIGHT.

For example,

2.71 \times  {10}^{3}  = 2.71 \times 1000 \\  = 2710

Note that the exponent has a positive value. Therefore, we have to move the decimal point 3 times TO THE RIGHT. Producing 2710 as the answer.

Find the value of x in the triangle shown below.<br> a. x=80<br> b. x=48<br> c. x= 32<br> d. x=12
yulyashka [42]

THEOREM:

• <u>Pythagorean theorem</u>:— In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides.

ANSWER:

By pythagorean property,

x² = 4² + 8²

x² = 16 + 64

x² = 80

x = √80 units.

So, <u>Correct choice</u> - [A] √80 units.

What is the circumference of a circle whose radius is 13?
Inessa05 [86]

Answer:

Circumference, C = 81.68 units

Step-by-step explanation:

Given that,

The radius of the circle, r = 13 units

We need to find the circumference of the circle. The circumference of a circle is the sum of the outer boundary. For a circle, it is given by :

C=2\ \pi r

C=2\ \pi \times 13

C = 81.68 units

So, the circumference of the circle is 81.68 units. Hence, this is the required solution.
