What is the wander to 6x25 x?
2x80
What is 2 over 3 of 240?
(2/3)x240 = 2x80 = 160
How do you use the distributive property to multiply 22x85?
22x85 = (20 + 2)x(80 + 5) = 20x(80 + 5) + 2x(80+5) = 20x80 + 20x5 +2x80 + 2x5 = 1600 + 100 + 160 +10 = 1870 Although if I were doing it in my head I'd probably just do 22x85 = (20 + 2)*85 = 20*85 + 2*85 = 1700 + 170 = 1870.
How should you prepare for the Track Season?
If you're a sprinter, you should be doing interval workouts, such as running 2x90 2x80, 2x70 meter workouts, it is espescially to work on lifting weights, don't try to max out but do lots of reps to make yourself explosive.Depends on what you're doing.Sprints-2 weight liftings a week and 3 track trainings (block work, 5x80m ect)Middle distance- 2 long runs a week at jog pace, and 3 speed sessions such as jog for a lap sprint a lap x4
A hammer is dropped off a roof of an apartment building that is 80 meters high How long will it take to hit the ground?
The hammer will take square-root(2x80/9.8)= 4.04 seconds to hit the ground. The distance is related to the time by s=v0t + 1/2 gt^2 where vo, the initial velocity is=0. The answer is 4.04 or rounded is 4 seconds.
Is a 140 out of 240 a good psat score?
PSAT (Preliminary Scholastic Aptitude Test) score report is made up of three scores - critical reading, math and writing. Those score will range from a low of 20 to 80 as the highest. So the PSAT range would be 60 (3x20) being the lowest and 240 (2x80) the highest. In 2009, the average score grade 11 was 47 in reading, 48 in math, and 46 in writing. Grade 11 total 141. The average score for grade 10 was 42 in reading, 43 in math and 41 in writing. Grade 10 total 126. A minimum of 201 is needed to apply for a scholarship.
If a sprinter has a mass of 80 kg and a kinetic energy of 3000 what is the speed?
Although the units of the kinetic energy aren't given, we have to assume that the "3,000"are joules ... the SI unit of energy; otherwise we can't go anywhere at all with this question.K.E. = 1/2 m V2 = 3,000 joulesm V2 = 6,00080 V2 = 6,000V2 = 6,000/80 = 75V = sqrt(75) = 8.66 meters per second (rounded)
