Answer:
Step-by-step explanation:
- So first we have to find out the total number of points possible
- So he took 5 tests each with a max score of 100 points, so that's 500 points total
- The final test will be 150 points, so his whole grade is out of 500+150= 650 points
- He has already scored 460 of those 650 points
- Now how much must he get in the least, on the last test in order to make 90%?
- Now we need to find what 90% of 650 points is
- so
- Then we ask ourselves, how much must we add to 460, to get 585 points? 585-460= 125 points
- So Mark needs to get either 125 points or more on the next test to make 90% or more
- Now let's say the letter
means whatever grade number Mark gets on his next test
- This number must not be less than 125, so it must be either equal to or greater than 125 points
- So

<h3>Part A</h3><u>Multiply the energy produced in 1 second by the number of seconds:</u>
erg
10⁻³ is same as 0.001 times and 10³ is same as 1000 times.
1.6*1000 = 1600 mm = 160 cm = 1.6 m is way too big for the measurement of the distance between the tracks on a CD.
So the first option is correct.
