Answer:
Area of the given regular pentagon is 61.5 cm².
Step-by-step explanation:
Area of a regular polygon is given by,
Area =
Here, a = Apothem of the polygon
P = Perimeter of the polygon
Apothem of the regular pentagon given as 4.1 cm.
Side of the pentagon = 6 cm
Perimeter of the pentagon = 5(6)
= 30 cm
Substituting these values in the formula,
Area =
= 61.5 cm²
Therefore, area of the given regular pentagon is 61.5 cm².
D) It is the sum of the initial amount and the additional amount after d days.
He is adding them together to find the sum, not multiplying them together to find the product.
Answer : The greatest number of red marbles is 24.
Explanation:
Let the number of red marbles be x
Let the number of blue marbles be y
Since we have given that sum of blue and red marbles is atmost 36
i.e. x+y ≤ 36 (Equation 1)
and we have also given that red marbles is twice of blue marbles .
i.e. x= 2y ( Equation 2)
By putting the value of x from( Equation 2) in ( Equation 1) ,
we have,
2y+y ≤ 36
⇒ 3y ≤ 36
⇒ y ≤
⇒ y≤ 12
Now, we put the value of y in Equation 1
x+ 12 ≤ 36
⇒ x ≤ 36-12
⇒ x ≤ 24
So the greatest number of red marbles are in the bags is 24 .
Unit rate is feet per 1 second
117/6.5=18/1=18ft per second
Yes they are similar. I believe one of them is smaller and upside. The size is different but the shape is the same!
Hope this helped :)
