Answer:

The correct option is 1.

Step-by-step explanation:

The given expression is

3.5\times 2+9(7.1+0.5)+4

To solve these type of expressions we have a rule that is known as BODMAS.

BODMAS = brackets of division, multiplication, addition, subtraction.

It defined the order of calculations. It means first we have solve the brackets, then division, then multiplication, after that addition and last subtraction.

So according to BODMAS, Claudio should simplify the bracket first.

The bracket of given expression is (7.1+0.5).

The simplification of given expression is shown below.

3.5\times 2+9(7.6)+4               (Brakets)

7+68.4+4                                  (Multiplication)

79.4                                          (Addition)

Therefore he will solve (7.1+0.5) first. So, option 1 is correct.

The given speed in kilometers per sec to miles per hour is 51449.534 mph.

Given that, the Oyo Empire if they are traveling 23 kilometers per sec.

<h3>What is the speed?</h3>

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

Now, the conversion of kilometers per sec to miles per hour is as follows:

To convert a kilometer per second measurement to a mile per hour measurement, divide the speed by the conversion ratio.

Thus, mph = km/s ÷ 0.00044704

Now, 23/0.00044704

= 51449.534 miles per hour

Hence, the given speed in kilometers per sec to miles per hour is 51449.534 mph.

Answer:

Circumference ≈ 82.9

Step-by-step explanation:

The formula for calculating the circumference of a circle is:

C = 2πr

Where 3.14 is pi (as stated on your screen)

And r is the radius.

Knowing this substitute those values

C = 2(3.14)(13.2)

Multiply 2 and 3.14.

C = (6.28)(13.2)

Multiply 6.28 and 13.2.

C = 82.9 when rounded.
