Write 12,400,000 in scientific notation.

a.1.24*10^[7]
b.1.24*10^[4]
c.1.24*10^[1]
d.12.4*10^[7]

A ) .

Step-by-step explanation:

Given  : 12,400,000 .

To find : Write 12,400,000 in scientific notation.

Solution : We have given 12,400,000 .

Steps to write in scientific notation :

Step 1 : If a number has n digit we move decimal point ( n-1) place to left  and to balance , multiply by .

We can see there are n = 8 in 12,400,000 .

So, we move decimal point 7 place to the left .

Then  .

Therefore,  .

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180

d no solution
