Mr. Lyle made a round trip between two cities that were 450 kilometers apart. On the return trip, he increased his average of rate travel by 5 km/h and made the trip in one hour less. Find his rate for each direction.

Answers

Answer:

45 km/h

50 km/h

Step-by-step explanation:

Distance traveled in one way = 450 km

Let x = Velocity when he was going to his destination in km/h

He traveled 5 km/h faster when he returned so his velocity was [tex]x+5[/tex]

It took him 1 hour less when he returned so

[tex]\dfrac{450}{x}-\dfrac{450}{x+5}=1\\\Rightarrow x^2+5x-2250=0\\\Rightarrow x=\frac{-5\pm \sqrt{5^2-4\times 1\times \left(-2250\right)}}{2\times 1}\\\Rightarrow x=45,-50[/tex]

So, velocity while going to his destination is 45 km/h

While returning his velocity was 45+5 = 50 km/h.

At an amusement park, 40 percent of the tickets were sold in the first hour. If 800 tickets were sold in the first hour, which equation can be used to find the total number of tickets sold for the entire day?
StartFraction 800 divided by 40 Over 40 divided by 40 EndFraction = StartFraction 20 Over 1 EndFraction
StartFraction 100 divided by 4 Over 800 divided by 4 EndFraction = StartFraction 25 Over 200 EndFraction
StartFraction 40 times 20 Over 800 times 20 EndFraction = StartFraction 800 divided by 16,000 EndFraction
StartFraction 40 times 20 Over 100 times 20 EndFraction = StartFraction 800 Over 2000 EndFraction

Answers

Answer: 2000 tickets were sold

Step-by-step explanation:

8000 divided by 40 percent is 200

If 800 tickets were sold in the first hour, the equation representing the given condition is [tex]\frac{40 \times 20}{10 \times 200}= \frac {800}{2000}[/tex]. Option D is correct.

What is the percentage?

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

If 800 tickets were sold in the first hour, the equation representing the given condition is [tex]\frac{40 \times 20}{10 \times 200}= \frac {800}{2000}[/tex]. Option D s correct.

It is given that 40 percent of the tickets were sold in the first hour and 800 tickets were sold in the first hour,

Let the total ticket be x

40% of x =800 tickets

x = 800/40%

x=800×100/40

x=20×100

x=2000

As a result

40% of 2000 =800 tickets

(40/100)×2000 = 800

Rearrange the equations we get,

800/2000=(40×20)/(100×20),

Hence, if 800 tickets were sold in the first hour, the equation representing the given condition is [tex]\frac{40 \times 20}{10 \times 200}= \frac {800}{2000}[/tex]. Option D is correct.

Answers

I'm assuming you mean that <C=68 degrees.

Now we know that the interior angle of a triangle adds up to 180 degrees.

We just need to subtract the 2 already known angles from it.

180 degrees-56 degrees-68 degrees=180 degrees-124 degrees=56 degrees.

Done!

<B=56 degrees.
