Answer:
7 students.
Step-by-step explanation:
To pass science, a student requires at least 70 grades so students who scored below 70 will be failed.
From the given bar chart we can calculate the number of students who scored below 70 grades
Students who earned 50 - 59 = 2
Students who earned 60 - 69 = 5
Therefore, number of students who failed were
2 + 5 = 7 students.
Step-by-step explanation:
15^2-12^2
225-144
81
√81=9
21÷9=2.3333(recurring)
2.33333×15=x
X=34.999
or X=35 to 1 d.p

Answer:
d = 24
Step-by-step explanation:
The area of a circle is given by A = π * r²
We are told the area of the clock is 144π.
Let's clear the formula for the radius:
r² = A / π
r² = 144π / π
r² = 144
r = √144
r = 12
The diameter is two times the radius, d = 2r = 2*12 = 24.
