Answer:
π m
Step-by-step explanation:
Arc length = 2πr
where r = radius and 0 = central angle
The given radius is 4m and the given central angle is 45°
Thus, arc length = 2π4
* simplify *
( note when simplifying we leave our answer in terms of π as the answer choices do. )
2 * 4 = 8
arc length = 1π
Hence, arc length = 1π or just π
830$ there are 52 weeks in a year. 52 times 15 is 780. 780 plus 50 is 830
Will you please provide more information and state a clear question
Answer:
I believe it is y = 15
Step-by-step explanation:
So you have
25x+10y=24
and
x+y=20
you can eith er subsitue or add
let's add
mutliply x+y=10 by -10
-10x-10y=-200
add to first equation
25x+10y=24
<u>-10x-10y=-200 +
</u>15x+0y=-176
15x=-176
divide both sides by 15
x=-176/15
subsitue
x+y=20
-176/15+y=20
add -176/15 to both sides
y=476/15
solution
(x,y)
