Perpendicular has slope that multiplies to -1 in other sloope
thsi one
2x-5y=-35
-5y=-2x-35
y=2/5x+7
slope=2/5
2/5 times -5/2=-1
y=-5/2x+b
findn b
(10,4)
(x,y)
4=-5/2(10)+b
4=-25+b
21=b
y=-5/2x+21
2y=-5x+42
5x+2y=42
Answer:18 inches
Step-by-step explanation: Try calculating the decimation of 7.581
Answer:
Step-by-step explanation:
In acidic reaction , equivalent weight of potassium dichromate is
mol weight / 6
= 294 / 6
49 g
equivalent weight of alcohol = 46 g
31.05 cc of .06M of potassium dichromate
= 31.05 x .06 cc of M potassium dichromate
= 1.863 cc of M potassium dichromate
= 1.863 x 6 cc of N potassium dichromate
= 11.178 cc of N potassium dichromate
== 11.178 cc of N alcohol
= (11.178 / 1000 ) x equivalent weight of alcohol
= (11.178 / 1000 ) x 46 g
= .514 g
30 g of blood contains .514 g of alcohol
100 g of blood contains (0.514 / 30) x 100
= 1.71 % of alcohol.
The answer should be length: 4 ft
