let the no. is x then 9x-2x=21 =>7x=21 =>x=3
x+y=40 (1/x)+(1/y)=(2/5) =>x+y=(2/5)xy =>40(5/2)=40y-y^2[ since x+y=40 =>xy+y^2=40y] =>y=20+5(12)^(1/2)=a or 20-5(12)^(1/2)=b[pythagorus theorem] now if x=a then y=b & vice-versa
solve both of the equations for y if the slopes are recipricals of one another the lines are perpendicular otherwise if they are the same slope they are parallel
f(x)=-9x-10 if you read your text it states that slope intercept form is y=mx+b where m is the slope here -9 and b is the y (or f(x) )intercept -10. to find the solution to the system look at the solution I gave for your other problem and use the same
you have to divide both sides by a negative 0.4 doing this changes the < to > by rule. x>-12/-.4 = x>30
use order of operations First solve in parentheses then exponents then multiplication and division then addition and subtraction. 5(-39-(-74-85))=5(-39+(159))=5(120)= 600
two equations two unknowns: 3r - 2s = 0 2r + 3s = 13 3r - 2s = 0 =>r=2s/3 Substituting in (eqn 2)=> 2*2s/3 +3s = 13 solve for s =>s((4/3)+3)=13=>s(13/3)=13=>s=3=>using eqn 1 r=2
Altruism is the selfless concern for the welfare of others. In order to answer this question you have to think why people help others (which is more philosophical).

petroleum has many different compounds all with different chain lengths so if it is heated the smaller chain length molecules rise and the heavier stay at the bottom due to density differences
212 min / 60 min/hr = 3 hrs 32 minutes + 9 hrs = 12 hrs 32 minutes

for the first one find the amount moved total east west. Movement lateral=(east)- (west) 30cm - 15cm = 15 cm now find the longitudinal movement Movement longitudinal = 25 cm the maginitude is the distance moved relative to original postion which is given
Density is mass/unitvolume. for instance the density of water is approximately 1000 grams per Liter. So in one liter of space there is 1000 grams of water.
it looks like you could just solve for 2^x=(1*365*24*3600) =>xln(2)=ln(1*365*24*3600) => x=ln(1*365*24*3600)/ln(2) oh and at 1 for the series begining at 1 not zero. appoximately 26 times.

I believe that one accompanies acute lymphoblastic leukemia.
When components are alike they tend to be able to dissolve one another. water is a polar molecule where as acetaminophen is also polar so it will dissolve
The abyssal plain is formed when the lower crust (sima), is melted and pushed up by the up-welling mantle, reaches the surface at mid-ocean ridges and forms new oceanic crust. Therefore it is mainly composed of basalt or volcanic rock not so much sand

one can determine if two lines are perpendicular if thier they share a common point and the product of thier slopes are -1
speed of sound in air at atmosphere v = 331 m/s + (0.6 m/s/C)•T v=wavelength * Frequency => wavelength= v/Frequency = 0.46 m if 732 were first harmonic => Length being 7th harmonic = 7 * 0.46 m = 3.22 m
2.5 moles of each implies 86.18g/mole*2.5moles=215.5g 215.5 g / .660 g/mL = 326.4 mL 88.15 g/mole * 2.5moles=220.4g 220.4 g / .814 g/mL = 270.7mL
