259 Students go on a field trip. There are 19 vehicles, some vans and some buses.
Sunny_sXe [5.5K]

Answer:

12 vans

7 Buses

Step-by-step explanation:

I tried multiple versions but I finally got it right.

Since the buses can hold 25 students at a time I multiplied it by 7.

7 x 25 = 175

Then you'll need to find the remainder.

259-175 = 84

This number would be used to find the students going in the van

84/7= 12

So in total there would be 12 vans

and 7 buses

I hope this helps

(HELP ASAP PLEASE AND THANK YOU..)
Zigmanuir [339]
Hello!

As you can see, two of the triangles that we see that are made from the lengths we are given make up one face of the pyramid. We can use the triangle formula without multiplying by 1/2 to find the length of one face.

30(45)=1350

Now we multiply this by  four to find all of the sides.

1350(4)=5400

We find the area of the square base

30(30)=900

Finally, we add up our lengths.

5400+900=6300

Therefore, our answer is C) 6400 yards²

I hope this helps!

A) 3.3 m/s

1 km/ 5 minutes
=1000 m/ 5(60) s
= 1000 m/ 300s

Measurement of a 18 gon of its interior and exterior
ExtremeBDS [4]

There will be 18 exterior angles, each of 360/18 = 20 deg. So each interior angle, which is supplementary to the exterior angle will be 180–20 - 160 deg. The sum of the 18 interior angles = 18*160 = 2880 deg.
