How many times would a member and a non member have to rent a boat in order to pay the same amount
Yakvenalex [24]
X = number of times they rent a boat. 

Members 
Cost = 105 + 9.50x
Non-members because members don't have to pay the 105 so we gotta leave it out. 
Cost = 14.75x 

Now to determine whether the cost would be equal, we need to set the two equations equal to each other.

105 + 9.50x = 14.75x 

Now solve for x

105 = 5.25x
 
20 = x 

<span>That's your answer.</span><span> They would have to rent 20 times to equal each other. </span>

Amelia is building 3 square garden beds that are all the same size. She arranges them side-by-side to seperate the certain plant
bazaltina [42]

Answer:

3(s x s)

Step-by-step explanation:

You can find the area of each garden bed by multiplying the length of each square, and since a square has four equal sides, the area of one square would be s times s. S times s equals the area of ONE square, so you would take that area and multiply it by three, since you have three squares. Hope this helps!

A satellite can move at 17,000 miles per hour. How many hours will it take to reach a star that is three light years away? Recal
babunello [35]
First convert the distance to miles 

<span>9.5 × 10^12 km x 0.62 miles/km </span>
<span>= (0.62 × 9.5) x 10^12 miles </span>
<span>= 5.9 × 10^12 miles </span>

<span> we want to triple that, because it is 3 light years (not just 1): </span>
<span>3 x 5.9 × 10^12 miles </span>
<span>≈ 18 × 10^12 miles </span>
<span>≈ 1.8 × 10^13 miles </span>

<span>Next divide by the speed to get the time (in hours). </span>
<span>t = 1.8 × 10^13 miles / 17000 miles/hour </span>

<span>convert the speed to scientific notation: </span>
<span>t = 1.8 × 10^13 / 1.7 x 10^4 </span>

<span>t = (1.8 / 1.7) × (10^13 / 10^4) <-- when dividing powers with the same base, subtract the exponents </span>
<span>t ≈ 1.1 × 10^9 </span>

<span>convert that back to standard notation. </span>

<span>Answer: </span>
<span>1,100,000,000 hours (P.S. That is about 120,000 years).
Hope this helps!!!</span>

G(x)=3x^2-2x+7/2x+5 <br> find g(-1)
KengaRu [80]

Answer:

g(- 1) = 4

Step-by-step explanation:

To evaluate g(- 1) substitute x = - 1 into g(x)

g(- 1) = \frac{3(-1)^2-2(-1)+7}{2(-1)+5} = \frac{3+2+7}{-2+5} = \frac{12}{3} = 4
