Simplify 12 × 10 ^8/ 4 × 10^5 and leave in ordinary form

Burka [1]

Answer:

3 x 10^3

Step-by-step explanation:

The first is to identify the operation to be performed, it is a quotient between two potency.

Being two potency of the same base number (10), the property says that the quotient of two potency of the same base subtracts its exponent, and the base remains the same.

The corresponding exponents are 8 and 5.

The subtraction is 8-5 = 3.

The whole number that accompanies the base is divided in a current way, that is 12/4. Therefore, the result is 3.

If measure of angle 1 = 2x+6 and measure of angle 2 = 8x+4 where angles 1 and 2 are supplementary, then how much is the actual m

nlexa [21]

Answer:

The actual measure of ∠1 = 40°

Step-by-step explanation:

We are given: ∠1 = 2x+6 and ∠2 = 8x+4

and both angles are supplementary. we need to find the actual measure of ∠1

Supplementary angles: If the angles are supplementary their sum is equal to 180°

In our case ∠1 +∠2 = 180°

2x+6+8x+4=180

Solving the equation to find x, then we can find the actual measure of ∠1

$2x+6+8x+4=180\\10x+10=180\\10x=180-10\\10x=170\\x=170/10\\x=17$

So, value of x = 17

Now, finding actual measure of ∠1 by putting x=17 in equation 2x+6

$\angle1=2(17)+6\\\angle1=34+6\\\angle1=40$

So, the actual measure of ∠1 = 40°

Solve for n. d=4m + 7n n

Inga [223]

Answer:

n = $\frac{d-4m}{7}$

Step-by-step explanation:

Given

d = 4m + 7n ( subtract 4m from both sides )

d - 4m = 7n ( isolate n by dividing both sides by 7 )

$\frac{d-4m}{7}$ = n
