Step-by-step explanation:
2( l + w ) = perimeter of triangle
P = 2( 10+8 )
p= 2(18)
p= 36cm
Circle = pie (r) + d. recall d = 2r
P= 3.142 (4) + 8
P= 20.57~
so therefore= , 36 + 2(20.57)= 77.14cm ~ to the nearest tenths
Answer:
5
Step-by-step explanation:
20% of p = 10
20% = 0.2
Multiply
0.2p = 10
Multiply both sides of the equation by 5
p = 50
Find 10% of p
10% = 0.1
Multiply
0.1(50)
5
10% of p is 5
Hope this helps :)

I hope you mean 1/5 when you say 1 5. If that's what you mean, then both, Joshua and Melanie, are correct because, both of their equations are the same.
Joshua's - <span>8 ÷ 1/5 = 40 (Since we can divide a number by fraction, we use this rule: keep, change flip. When we use that Joshua's equation turns into 8 * 5/1 = 8*5 = 40, same as Melanie's.)</span>
