Number 9 would be.
v = (4/3) * pi * 7^3
The question ask to complete the question that ask to calculate the total purchase price of on-sale item with a 6% sales tax and the answer would be letter D. Add the sales prices and multiply by 1.06. I hope you are satisfied with my answer and feel free to ask for more
Step-by-step explanation:
sellingprice−costprice
×100
95
sp−95
×100=80
openthebracket
95
100sp−9500
=80
100sp−9500=7600
100sp=7600+9500
100sp=17100
sp=171
2,000, 200 and 20 are similar except for the number of zeros.
You can remove a zero from each to equal the number of zeros in the divisor. So 80,000 ÷ 2,000 is equivalent to 80 ÷ 2 = 40 you just remove the 3 zeros
80,000 ÷ 200 is equivalent to 800 ÷ 2 = 400 you just keep removing 0s like for instance this time it was 2 lastly 80,000 ÷ 20 only allows us to remove 1 zero 8,000 ÷ 2 = 4,000. The smaller the divisor the greater the quotient when dividing the same number like for instance in this example 80,000
-9x^3-72x^2+36=3x^3+x^2-3x+8 Add 9x^3 to both sides.
-72x^2 + 36 = 3x^3 + 9x^3 + x^2 - 3x + 8 Add 72x^2 to both sides
36 = 12x^3 + 73x^2 - 3x + 8 Subtract 36 from both sides.
0 = 12x^3 + 73x^2 - 3x - 28
It does factor, but it is not very nice.
(x + 6.06)(x - 6.09)(x + 0.632)
