Answer: A

Step-by-step explanation:

$\frac{6.3\cdot \:10^8}{9\cdot \:10^2}$

$=\frac{6.3\cdot \:10^6}{9}$ --> Exponent rule for division, 10^8/10^2 = 10^6

= 700,000 --> In scientific notation, 7.0×10^5

Answer:

x = 12.25

Step-by-step explanation:

x : 14 = 7 : 8

x/14 = 7 /8

x = (7 * 14 ) / 8

= (7 * 7) / 4

=49 /4

= 12.25

x = 12.25

Based on the information on the diagram, what is the measure of angle ADC?

Serga [27]

Answer:

73°

Step-by-step explanation:

Given: BD=BE

∠DBE= 50°

∠EAC= 42°

DE//AC and AE=CD

Attach is the new drawn diagram with M point.

∵ we know BD=BE, ∴ ∠BDE=∠BED= x ( taking x as unknown angle)

Remember, sum of triangle= 180°

Now, ∠BDE+∠BDE+∠DBE= 180°

⇒ $x+x+50= 180$

⇒ $2x+50= 180$

Subtracting both side by 50, then dividing both side by 2

∴ $x= \frac{130}{2}= 65$ °

We know, ∠MAC= ∠MCA= 42° (∵AM=MC)

Next, ∠EDC=DCA= 42° ( ∵ Alternate interior angle as we know DE//AC )

Now, we have ∠EDC= 42°, ∠BDE= 65°

∴ $BDE+EDC+ADC= 180$ ° (∵sum of straight line= 180°)

⇒ $65+42+ADC= 180$ °

⇒ $107+ADC= 180$ °

Subtracting both side by 107

∴∠ADC= $180-107= 73$ °

∴∠ADC= 73°
