a large park in the shape of a parallelogram. The park has an area of 776 1/4 square yards. The base of the park 34 1/2 yards. m
My name is Ann [436]

Answer:

So, marta will sprint 225 yards.

Step-by-step explanation:

Area of parallelogram= b*h

Given: Area = 776.5 square yards

Base = 34.5 yards

Area = b* h

776.5 = 34.5 * h

776.5/34.5 =h

=> h = 22.5

Since sprint is the same distance as of height of park so,

Distance of  1 sprint = 22.5 yards

Distance of  10 sprints = 10 * 22.5 = 225 yards

Identify the height of a triangle in which b=(x−2) m and A=(x2−4) m2. A) h = (2x + 4) m B) h = (2x + 2) m C) h = (x + 2) m D) h
hjlf

Answer:we know that

area of triangle=b*h/2

b=(x-2) m

Area=(x²-4) m²

h=?

(x²-4)=(x+2)*h/2

but remember that

(x²-4)=(x+2)*(x-2)

so

subsititute

(x+2)*(x-2)=(x+2)*h/2

(x-2)=h/2

h=2*(x-2)

the answer is

the height of a triangle is 2*(x-2)

I'm stumped on this one. it's homework and I need help. thanks

Okay so in order to find the circumference we would first need to find either the diameter or radius of the circle. The perimeter of the square is 40 and each side is equal. 40/4 = 10. So the length of one side is 10. The length of one side would be the diameter of the circle.

Diameter = 10

The only thing that is left is to find the circumference.

The formulas for circumference are:
C = \pid
C = 2\pir

So just multiply the diameter by pi (3.14)

10 x 3.14 = 31.4
or 10\pi (Which would be the answer to your problem)
