90+75=165 165 student are divided in 15 groups 165/15=11 groups of people
The answer is going to be 7
to make 4 and 2/3 a fraction you multiply 4 times 3, and then add two, so it will com in as 14/3
then you take the multiplicative inverse of that fraction which would make is 3/14, and then you multiply it by 2/3
3*2=6
14*3=42
so it comes out as 6/42, then you take the multiplicative inverse of that, and it come in at 42/6, divide 6 into 42 and you get seven.
hope this helps
Answer:
217.04 cm²
Step-by-step explanation:
We should first calculate the area of the rectangle:
A= 14*21 =294cm²
then we should substract the area of the half-cercle :
A'= (7²*π)/2=76.96 cm²
then the area of the shaded area is :
A"= 294-76.96= 217.04 cm²
