Answer:
53 teachers
Step-by-step explanation:
Basically, what we need to do here is to find how many teachers there need to be, first. If there are 6,734 students in the school district and if maximum class size is 25, then the number of teachers needed is:
6,734 / 25 = 269.36
Of course, it's obvious that we can't have a decimal number of teachers, so we need to find integer (269 or 270).
If we take 269 teachers and 25 students per class, we get:
269 • 25 = 6,725 students, which is not enough, since there are 6,734 students.
That means that the number of teachers needed is 270.
It is given that there are already 217 teachers, meaning that 270-217=53 teachers have to be supplemented.
The answer is 58 milligrams !
Answer:
examples:
Perfect square- 9 multiplied by 9 is a perfect square because it = 81
(two same numbers multiplied together create a perfect square)
square units- on grid paper how many squares would be filled to creat 9 multiplied by 9
square roots- √81 ()using this symbol divide 81 into 2 and if the number you get is even then it is a perfect square
Answer:
Solve to get <em>y</em> by itself
multiple the denominator on both sides [It cancels on the side that has the denominator in the first place]
mx=y
Y = x + 3
3 x + 2 = y + 1
3 x + 2 = x + 3 + 1
2 x = 2
x = 1, y = x + 3 = 4
We have: 3 x + 2 = y + 1 and: y = x + 3.
It means that we have 4 equal triangles ( O is the centre ):
ΔTOS, ΔSOR, ΔROQ, ΔQOT.
∠ 1 = 53°
∠ 2 = (180° - 2 · 53°) : 2 = 37°
Answer: C ) 37°
