<span>In a scientific notation, you have to put a decimal right after the first number (unless it is a zero). How many times you move the decimal from its original spot determines the answer. (FYI: In a number like 196 the decimal point is 196.000<--here)</span>

<span /><span>1.
5.8927 (moved the decimal point 4 times, so the answer is --->)  5.8927×10^{4}</span>

<span>2.
1.304×</span><span>10^{9}</span>

<span>3.
6.73×10^{6}</span>

<span>4.
1.33×10^{4}</span>

<span>5.
9.77×10^{22}</span>

<span>6.
3.84×10^{5}

Example on worksheet (subtracting by adding up)
Lisa [10]

Answer:

(49 - 29) + 1 =(50 - 29)

Step-by-step explanation:

The 20 comes from the subtraction of 29 in both sides of the previous step equality. In the following, I transcript the complete procedure and I add the step that you need to understand why 20 appears (in bold numbers):

29+20=49

49+1=50

(49 - 29) + 1 =(50 - 29)

20+1=21

50-29=21

hence, it was only nesseraty to subtract 29

Given: AD = BC and AD || BC
o-na [289]

Answer:

See below

Step-by-step explanation:

<u><em>Proof:</em></u>

<u><em>Statements  </em></u>                                  |  <u><em>Reasons</em></u>

AD ≅ BC                                         | Given

AD ║ BC                                         | Given

AC ≅ AC                                         |  Reflexive Property

∠DAC ≅ ∠ACB                               | If 2 || lines are cut by a trans., the                                                                       |  alternate interior ∠s are congruent.

ΔADC ≅ ΔBCA                               | S.A.S  Postulate

BA ≅ DC                                         | Corresponding sides of congruent Δs

So, quad. ABCD is a ║gm             | If a quad. has its opposite sides

                                                       | congruent, the quad. is a parallelogram.

Does anyone know where the a in front of the parentheses for the LCD : a(a+5)(a-6) came from?
lukranit [14]

Answer:

See below

Step-by-step explanation:

If you factor a^2-a-30 you get \left(a^2+5a\right)+\left(-6a-30\right)

= a(a+5)-6(a+5)

= a(a+5)(a-6)

That's where the a comes in

Not sure if that answers your question
