If the areas of two similar hexagons are to each other as 5 : 2, and one side of the first hexagon is 25, what is the corresponding side in the other hexagon?

Answers

The area of a hexagon is given by (3sqrt(3) / 2) x a^2 where a is the side of the hexagon. Given that the ratio of the area of two similar hexagons is 5 : 2. This means that the ratio of the square of the sides is 5 : 2. Let the corresponding side in the other hexagon be x, then: 25^2 : x^2 = 5 : 2 625 / x^2 = 5 / 2 x^2 = (625 x 2) / 5 = 250 x = sqrt(250) = 15.8 Therefore, the corresponding side in the other hexagon is approximately 15.8

b. 43.218 m/s
c. 43.22 m/s
d. 43.2 m/s

Answers

I think you are asking for the quotient of the numbers because base from the choices the units are meters per second and the given has units of meters and seconds. So, the quotient of the numbers is 43.218 meters per second which is option B.

Answer:

9. obtuse isosceles

10. equiangular equilateral

For 10., it is also acute equilateral, but if you can pick only one answer, go with the answer above which is more descriptive.

Step-by-step explanation:

9.

Two sides are congruent. The third side is not congruent to the other two.

According to sides: isosceles triangle.

One angle is obtuse.

According to angles: obtuse triangle

10.

All sides are congruent.

According to side: equilateral triangle.

All angles are congruent, and each angle measures 60 deg. All angles are acute.

According to angles: equiangular triangle

According to angles: acute triangle.

both are the first answers

In the neighborhood park there is a circular grassy picnic area, but half of the grass has died. The city wants to replant the grass, but needs to know the square footage of the damaged area. If the circular picnic area is 150 feet across, what is the square footage of the damaged area? Let π = 3.14.A) 471 sq. feet
B) 8831.25 sq. feet
C) 17662.5 sq. feet
D) 35325 sq. feet

Answers

so, πr^2 is the equation for the area of a circle, if we calculate that, it will equal 17662.5

we then half that to get the area (square feet) of the dead grass, which is 
8831.25 square feet which means the answer is B.
150 feet across is diameter
find area
but 1/2 is dead
find area then times 1/2

area=pir^2

150=d
d/2=r=150/2=75=r

area=pi75^2
area=5625pi
times 1/2
area=2812.5pi
pi=3.14 for this problem
area=8831.25

B is answer
