Elan Coil [88]

Answer:

With the amount of fuel she has, she can drive 120 km which will take 2 hours.

Step-by-step explanation:

You need to figure out which information is necessary for this problem and which is not.

The fuel tank has 20 L.

The car drives 6 km per L.

20 L * 6 km/L = 120 km

She can drive 120 km with the amount of fuel she has.

She is driving at 60 km/h.

speed = distance/time

time * speed = distance

time = distance/speed

time = (120 km)/(60 km/h) = 2 hours

Answer: With the amount of fuel she has, she can drive 120 km which will take 2 hours.

Charlotte is running at a rate of 9\,\dfrac{\text{km}}{\text{h}}9 h km 9, start fraction, start text, k, m, end text, divided

OverLord2011 [107]

Answer:

2.5 meters per second

Step-by-step explanation:

Given,

The speed of Charlotte = 9 km/h

That is, the distance covered in 1 hour = 9 km,

∵ 1 km = 1000 m

So, the distance covered in 1 hour = 9000 m,

∵ 1 hour = 60 minutes and 1 minute = 60 seconds,

⇒ 1 hours = 3600 seconds,

∴ The distance covered in 3600 seconds = 9000 m,

⇒ Distance covered in 1 second = $\frac{9000}{3600}$ = 2.5 m,

Hence, his/her speed = 2.5 meters per second

I think that C would be the best answer because you have to multiply and then divide.

I have no idea where to start

Sliva [168]

Let me know if you want the answer, but what you need to do first is get the opposite angles.

They're on straight lines, so 180 minus that angle would equal the angle inside the triangle.

Then all inner angles if a triangle add up to 180° so 180 minus the two other angle would give you the final missing angle.

Do the straight line thing again and subtract 156 from it.
