The average annual precipitation on Mt. Washington, in New Hampshire, is 90 inches. During one particularly wet year, different news reports carried the following statements.
The precipitation this year is 200% of normal.
The precipitation this year is 200% above normal.
Do the two statements have the same meaning? That is, how many inches of precipitation is implied by each one? Explain.

If t8 = 4 and t12 = −2, find the first three terms of the arithmetic sequence.

Aline has a slope of . which ordered pairs could be points on a parallel line? check all that apply. (-8, 8) and (2, 2) (-5, -1) and (0, 2) (-3, 6) and (6, -9) (-2, 1) and (3,-2) (0, 2) and (5,5)

Aspacecraft can attain a stable orbit 300 kilometers above earth if it reaches a velocity of 7.7 kilometers per second. the formula for a rocket's maximum velocity v in kilometers per second is vequalsminus0.0098tplusc ln upper r, where t is the firing time in seconds, c is the velocity of the exhaust in kilometers per second, and r is the ratio of the mass of the rocket filled with fuel to the mass of the rocket without fuel. find the velocity of a spacecraft whose booster rocket has a mass ratio of 20, an exhaust velocity of 2.1 km/s, and a firing time of 15 s. can the spacecraft achieve a stable orbit 300 km above earth?
