Answer:

3.14

Step-by-step explanation:

Circumference of a circle is given by

C=\pi d and making \pi the subject then

\pi=\frac {C}{d}

Here d is the diameter and C is the circumference.

Given that d=10cm and C=31.4 then

\pi=\frac {31.4}{10}=3.14

The simplification form of the expression (1.93 × 10⁷) − (9.7 × 10⁶) is

9.6×10⁶ and the correct order is shown in the picture.

<h3>What is an integer exponent?</h3>

In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.

We have:

\rm =\left(1.93\times \:10^7\right)-\left(9.7\times \:10^6\right)

\rm =\left(1.93\times \:10^7\right)-\dfrac{10}{10}\left(9.7\times \:10^6\right)

\rm =\left(1.93\times \:10^7\right)-\left(0.97\times \:10^7\right)

= \rm (1.93-0.97)\times 10^7

= 0.96\times 10^7

= \dfrac{10}{10}(0.96\times 10^7)

= 9.6×10⁶

Thus, the simplification form of the expression (1.93 × 10⁷) − (9.7 × 10⁶) is

9.6×10⁶ and the correct order is shown in the picture.

slamgirl [31]
Small angle - x
large angle - 3x-8
supplementary = sum of this angles = 180
x+3x-8=180
4x-8=180
4x=188
x=47  
large angle  3x-8=3*47-8= 133°
check: 133+47=180
