Answer: Each lap that Marshall runs has 452.16 yards
Step-by-step explanation:
Because the lap is circular, we know that the distance from the center of the track to any point of the path must be the same.
We know that he walkerd 72 yards, from the center to the path, se we know that the path is a cirlce of radius equal to 72 yards.
The perimeter of a circle is equal to P = 2*pi*r
where pi = 3.14
so we have that the perimeter of the track is 2*3.14*72 yards = 452.16 yards.
So each lap that Marshall runs has 452.16 yards
Step-by-step explanation:
Q1. diameter =90yd radius=45
circumference of circle=2×pi×radius
"" =2×3.14×45
=282.6 yd
Q2 diameter =18m radius=9
area of circle=pi×(radius)
""" =3.14×9²
""" =254.34m²
-11-4 - (-b+3)
Distribute the negative sign
-11-4+b-3
Simplify like terms -11, -4, and -3, making sure to remember their sign.
-11-4-3 = -18
So the answer would be b-18 or -18+b.
Answer:
x=6°
Step-by-step explanation:
7x+180-23x+10x+36=180
-6x=180-180-36
-6x=-36
divide both sides by-6
x=6°
Answer:
45.55 meters
Step-by-step explanation:
I'm guessing she recorded above her height, right?
To find the height of the dam, use the tangent ratio:
The height of the dam is the side opposite the given angle, and this will represent x. The adjacent side (the hypotenuse is NEVER considered the adjacent side) is the distance from Scarlett to the dam. The angle of elevation is the angle of 26°. Insert the values:
Solve for x. Multiply both sides by 90:
Insert equation into a calculator:
Now add Scarlett's height:
The dam is 45.55 meters tall.
<em>Finito</em> :D
