Answer:
A-75 and B-25
Step-by-step explanation:
Firstly, divide the 200 students by the amount of sections (8) and that gives you 25 a section. Since year 7 has 3 sections and year 9 has 1, 3(25)=75 and 25(1)=25.
Answer:
Step-by-step explanation:
2 + 32 = 5 + 3z
34 = 5 + 3z
3z + 5 = 34
3z + 5 - 5 = 34 - 5
3z = 29
3z ÷ 3 = 29 ÷ 3
Answer:
first calculate the area of the arch using:
O/360×πr2
O represents theta
second calculate the area of the circle using πr2
finally minus the answer gotten from the two different areas
thats how u get the area of the shaded area
That is the standard form
