to use the distributive property you need to multiply everything inside the parentheses by what is outside of the parentheses. First you would do 1/2 x 4x and you get 2x. Then you do 1/2 x -6y and you get -3y. The rewritten expression would be 2x-3y
Hope this helps
V=(1/3)hpir²
ok, so inscribed
therefor the edge length is the diameter of the cone (the base is on bottom)
so then d=6
d/2=r
6/2=3=r
height
we need pythagoran theorem to find this
if we look at one side and draw the height then we get a right triangle with height is one leg
3 is another
and 9 is hyptonuse
a²+b²=c²
3²+h²=9²
9+h²=81
h²=72
h=6√2
h=6√2
r=3
V=(1/3)(6√2)(pi)(3²)
V=18pi√2 cubic feet
1. 980 ÷ 100 = 9.8 = 1%
9.8 × 14 = 137.2
2. 50 ÷ 5 = 10 = 20%
10 ÷ 2 = 5 = 10%
20% + 10% = 30%
3. 78 × 5 (because 20% is 1/5) = $390
4. 6000 ÷ 100 = 60 = 1%
60 ÷ 2 = 30 = 1/2%
6000 - 30 = 6970
5. 25000 ÷ 100 = 250 = 1%
250 ÷ 5 = 50 = 1/5%
250 × 12 = 3000
3000 + 50 = 3050 = 12 1/5%
6. 75% is 3/4
12 ÷ 3 = 4 = 25%
4 × 4 = 16
7. 30/20 = 3/2 = 1.5
=150%
8. 20000 ÷ 100 = 200 = 1%
200 ÷ 4 = 50 = 1.4%
200 + 50 = 250
I hope this helps!
