Convert from Decimal Notation to Scientific Notation
Brrunno [24]

Answer:

Hence, 87,50,000 can be expressed as $8.75 \times 10^{6}$.

Step-by-step explanation:

- Given 87,50,000

- Use given, move the decimal point so that first factor is greater than or equal to 1 but less than 10 .

- Then count n and write in scientific notation.

Step 1 of 1

Consider 87,50,000.

8.75

So, 8.75 lies between 1 & 10 .

Now, Decimal moved to 6 places at left.

$8.75 \times 10^{6}$

So, $87,50,000=8.75 \times 10^{6}$.

Angie and Becky each completed a separate proof to show that the measures of vertical angles AKG and HKB are equal. Who complete
BigorU [14]

Linear pair angles, which are angles that together form a straight line are

supplementary angles.

The one that completed the proof incorrectly is <u>Becky</u>.

Reasons:

The two column proof is presented as follows;

Statement {}                                                             Reason

1. Segment GH intersects segment AB at K {}     1. Given

2. m∠AKG + m∠HKB = 180°    {}            2.Definition of Supplementary Angles

m∠GKB + m∠HKB = 180°

3. m∠AKG + m∠HKB = m∠GKB + m∠HKB      {}  3. Substitution property

4. m∠AKG = m∠HKB     {}                                      4. Subtraction Property

The difference between Angie's Proof and Becky's Proof is in Statement 2.

  • Angie states that; m∠AKG + m∠HKB = 180° and m∠GKB + m∠HKB = 180° by definition of Supplementary Angles

  • Becky states that; m∠AKG + m∠HKB = 180° and m∠GKB + m∠HKB = 180° by Angle Addition Postulate

Becky's proof is incorrect because the measure of angles  m∠AKG and

m∠HKB and m∠GKB and m∠HKB are not given, therefore, the use of the

reason of Angle Addition Postulate in statement 2. is incorrect.
