Answer:
15 students at school
Step-by-step explanation:
So there is 50 students in total
First subtract that much with how much students have the flu
1/10 = 5/50
So 5 students have the flu
That leaves 45 students
Then subtract that much with the amount of students that are remaining are on the field trip
45 divided by 3 = 15
so 2/3 = 30/45 (they can both be multiplied and divided by 15)
so 30 of the 45 students are on the field trip
45 - 30 = 15
That means there are 15 students left over at school
Answer:
A = 18 units²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A =
h ( b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ the parallel bases
By counting squares
h = 3, b₁ = 3, b₂ = 9 , then
A =
× 3 × (3 + 9) = 1.5 × 12 = 18 units²
The circumference of a circle has the formula: 2*pi*r. So, we could easily determine the value of r.
C = 2*pi*r
12*pi = 2*pi*r
12 = 2r
r = 12/2
r = 6 inches
Knowing the r, we could find the area which has the formula
A = pi*r^2
A = pi*6^2
A = 113.1 square inches
