Answer:

8. 1.2E

9. 1.2B

Step-by-step explanation:

Two planes intersect at a line.

Answer: 1.2E

When lines LM and MO intersect, point M is the same point on both lines. Points L, M, and O are not collinear, so they determine a plane.

Answer: 1.2B

Answer:

Your answer would be B.

Step-by-step explanation:

a^2 + 9^2 = 113^2

Solve exponents.

A^2 + 81 = 113

Subtract 81 from each side.

A^2 = 32.

Square root each side.

A = 32

A small airplane flies 1200 miles with an average speed of 300 miles per hour. 2 hours after the plane leaves, a Boeing 747 leav

inysia [295]

The small plane has the following parameters

Distance = 1200 miles

Speed = 300miles/hour

time = ?

$\begin{gathered} \text{Speed =}\frac{dis\tan ce}{time} \\ time\text{= }\frac{1200}{300} \\ \text{time = 4 hours} \end{gathered}$

If a Boeing 747 leaves 2 hours later, the total time becomes 4hours + 2 hours = 6 hours

Considering the distance of the small plane after 6 hours, we have

$\begin{gathered} \text{distance = sp}eed\times\text{ time} \\ d\text{ = 300 }\times6 \\ d\text{ =1800 miles} \end{gathered}$

So the total distance = 1800 miles

Hence the speed of the Boeing 747 will be

$\begin{gathered} \text{Speed =}\frac{dis\tan ce}{time} \\ \text{distance = 1800 miles } \\ time\text{ = 2hours} \end{gathered}$ $\begin{gathered} \text{speed = }\frac{1800}{2} \\ \text{speed = 900 miles/hour} \end{gathered}$

The average speed of the Boeing 747 is 900 miles/ hour
