algebra
70 = (75+63+68+x)/4 ...with x being what he must get. So you solve that: 70(4)-75-63-68 = x x = 74 So therefore, Sam must get a 74 or above to get a C grade. x => 74

Physics
Oh nvm, you mean F = 1/d^2 Got it...thanks.

Physics
but what is the 3^2 for? If the 3 is for the distance being tripled...what about the exponent 2?

Physics
If the distance between two objects is tripled, by what factor will the gravitational force between them change?

Chemistry
A sample of solid monoprotic acid with molar mass equal to 137.9 g/mol was titrated with 0.1879 M sodium hydroxide solution. Calculate the mass in grams of acid to be used if the volume of NaOH to be used is 25 mL.

Chemistry
If 1.000 kcal of heat is added to 1.700 L of oxygen in a cylinder at constant pressure of 1.00 atm, the volume increases to 2.100 L. Calculate the total energy change for this process.

Science
At what latitude (on Earth) is the elevation of the South Celestial Pole greatest?

Trigonometry
is that supposed to be zero or theta? if its theta: 1) theta = 23.6 2) theta = 53.1

Math
Find all values of x in the interval [0, 2 pi] that satisfy 2 cos x-1 = 0. cos x = 1/2 x = 60 How do I find the other value of x?

Chemistry
That means that AgNO3 is the limiting reactant as it has 0.0033 moles compared to 0.0039 for silver nitrate. But I don't get the last part you said. What same number of moles of silver bromate would I get? Do you mean same number of moles as the limiting reactant? Meaning ...
