Answer:
85%(estimated)
Step-by-step explanation:
150-22=128
changed ÷ original x 100%
128 ÷ 150 x 100%
≈ 85%
Sod=1*1
to cover =30*14
to cover=420
to cover divided by one piece
=420/1
=420 pieces
Answer:
Step-by-step explanation:
8x+9/x^2-13x+42
Write 8
x as a fraction with denominator 1
8x+9/x^2-13x+42
then we multipuly 8x/1 by x^2/x^2
Let x = amount invested at 8%
26000 - x = amount invested at 6%
0.08x + 0.06(26000 - x) = 1860
solving the equation you get x = 15000
and subtract that from 26000 you get 11000
8% investment = 15000
6% investment = 11000
The relations are domain and range
