63 students. To solve, you first ned to determine the total cost for each student by adding 300 and 5, which equals $305. You then need to see how many times $305 will go into $19215, which shows how many students went. $19215 divided by $305 equals 65.
Answer:
.08cm or 0.08cm
Step-by-step explanation:
First of all, we can see that 20mm is in millimeters, not centimeters.
If we convert the ones in centimeters to millimeters, it will result in decimals, which I want to avoid, but you could also do it that way.
There are 10 mm in 1 cm, so I multiply all of the values in cm by 10.
So now, we have that the volume is 1760mm, the length is 110mm, and the width is 20mm.
The formula for the volume of a cuboid is: 
We have the width, length, and volume, so let's plug it in.

To solve for h:
1. Multiply 20 and 100
2. Divide both sides by 2200

3. Divide right side
h = 0.8
Keep in mind that this is in millimeters. In centimeters, it would be .08
I think it’s 30 hope that helps
Answer:
C
Step-by-step explanation:
Since Δ ABC is isosceles , then AB = AC and the base angles are congruent.
∠ ACB =
=
= 65°
∠ ACB and ∠ BCE are adjacent angles and are supplementary, thus
∠ BCE = 180° - 65° = 115° → C
