Just look up 53 1/3 yards in feet. This would mean that the football field is 160 feet.
Answer:
AC = 18
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos30° = 
, then
cos30° = 
= 
= 
= ( cross- multiply )
2 AC = 12
× = 12 × 3 = 36 ( divide both sides by 2 )
AC = 18
For the answer to the question What is the speed of Mai if she <span>is riding her bicycle and she takes 6 hours to ride 38.4 kilometers.
I'll provide a solution to my answer below.
</span>time = 6hours
Distance = 38.4 Km
Speed = distance /time
= 38.4/6
= 6.4 km/h
I hope my answer helped you.
EQUATION 1) 2x - 3y = -4
EQUATION 2) 7x + 9y =- 5
Multiply the whole first equation by 3 so that we could find the values of X first.
1) 3(2x - 3y = -4)
1) 6x-9y=-12
2) 7x+9y=-5
Add the 2 equations together.
13x=-17
x=-17/3 OR -5 2/3
2x-3y=-4
Plug the value of X into the equation.
2(-17/3) -3y=-4
-11 1/3 - 3y=-4
-3y=-4+11 1/3
-3y=22/3
y=-22/9 OR -2 4/9
~Hope I helped!~
