Mr. Sato needs 9 magnets.
Explanation:
AS there are 24 students in the science class,
there are <span><span>242</span>=12</span> pair of students.
Mr. Sato wants to give each pair of students 3 magnets
Mr. Sato has already given 9 pairs of students their 3 magnets
Therefore number of pairs of students yet to be given magnets is <span>12−9=3</span>.
For them he needs <span>3×3=9</span> magnets.
Y=78
A polygon has a total of 5 interior angles
In order to find the total amount of angles in a shape you do (the amount of angles - 2)x180 degrees
(5-2(3))180
3x180=540
Add the numbers you know (10+20+30+40+50=150)
540-150=390 and there are 5y altogether so divide 390 by 5 which is 78
Answer:
1. He traveled 3/ 10 by train
2. 3/4 is the greatest
Step-by-step explanation:
3/ 10 = Iorry
2/5 = taxi
? = train
2=4
5=10
4+ 3 = 7
10 + 10= 10

17/20
Answer:
We can find the volume of a sphere using the volume of a cylinder. Cylinder is a solid which has a circular base. We know the fact that the volume of any solid is equal to the product of base area and height of the solid. So, the volume of a right circular cylinder of base radius ‘r’ and height ‘h’ is given by
