Answer:
1670
Step-by-step explanation:
Mas has 839 balls
37 are taken away
839 -37 = 802
Then he gets 868 balls
802+868 =1670
He now has 1670 balls
Answer:
24
Step-by-step explanation:
base (b) = 8
height (h) = 6
A = bh/2
= 8x6/2
= 48/2
= 24
2x2 for each pen with four in a square and one to the side kind of like this
=== ==
each length of fencing would be 2 meters and the total square footage would be 20 meters because some of the fencing is used for more than one pig's pen
the dimensions would be hard to show, but 4x4+ a 2x2
4sin x=2sin x + √3
4sin x-2sinx=√3
2sin x=√3
sinx=√3/2
x=arcsin √3/2=π/3 + 2Kπ U 2π/3+2Kπ
Sol: π/3 + 2Kπ U 2π/3+2Kπ ; K∈Z
π/3+2Kπ=60º+360ºk
2π/3+2Kπ=120º+360ºK
