I'll do 1 and 8, and you should then be able to do 2 and 9!

For 1, we can multiply these separately  - 3*4*9=108 and 5+7+2=13 (exponent multiplication is adding them!), so we have 108b^13

For 8, we can again add the exponents up to get (5/7)^8

Grace and her dad are planning to attend the state fair. An adult ticket is $15.00. The price of an adult ticket is one half the
Aleks04 [339]

Answer:

The equation is 1/2 x + 8 = 15 ⇒ answer A

Step-by-step explanation:

* Lets explain how to solve the question

- Grace and her dad are planning to attend the state fair

- The price of an adult ticket is $15

- The price of the adult ticket is one half the price of the student ticket

  plus $8

- Assume that the price of the student ticket is x

∵ The price of the student ticket is x

∵ The price of the adult ticket is half the price of the student ticket

   x plus 8

- lets multiply half by x and then add the result by 8

∴ The price of the adult ticket = 1/2 x + 8

∵ The price of the adult ticket is $15

- Equate the expression of the price of the adult ticket by the price of

 the adult ticket

∴ 1/2 x + 8 = 15

* The equation to determine how much Grace will pay for a student

  ticket is 1/2 x + 8 = 15

∴ The answer is choice A

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
