Answer:
423000cm²
Step-by-step explanation:
its multiply by 10000
The formula of triangle: height x base ÷2
here's how you can find x
x(2x+7)/2=92
2x^2+7x=92×2
2x^2+7x-184=0
x=8 or x=-11.5(rejected)
thus,the height would be 8
and the base would be: 2(8)+7=23
hope it helps!
Column Resolution
Rs = 2[(tr)y - (tr)x]/[Wx + Wy]
= 2[17.63 - 16.4]/ [1.11 + 1.21] = 1.06
Average no. of plates in the column for substance x
N = 16(tr/ W)^2
N = 16(16.4/1.11)^2
N = 3490 plates
Average no. of plates in the column for substance y
N = 16(tr/ W)^2
N = 16(17.63/1.21)^2
N = 3397 plates
Plates Height
H = L/N
For substance x
H = 30/3490
H= 0.00916905 cm/plate
For substance y
H = 30/3397
H = 0.00883132 cm/plate
Answer:
Step-by-step explanation:
Answer:
Step-by-step explanation:
rewrite you problem with the number as x
22(11) + 10 numbers next to eachother mean to multiply
242 + 10
252
