Answer:

1) 95% is the minimum

Step-by-step explanation:

If 5 tests were taken, and 100 pts each, and he received 77/100 on all 5 tests, then his grade would be 385/500 being 77%. Add another 100 pts to the denominator (for the last test) and 95 to the numerator, equaling 480/600, or 80%.

A 30cm board is cut down to be 25.5 cm. What is the percent decrease in length?
zmey [24]
Okie, so percent decrease is the amount loss divided by the original number and multiplied by 100 to find the percent. This is because you are finding the amount loss in terms of the total amount - percent basically.
The amount loss : 4 feet
4 feet/ 12 feet = .3333 (ratio of how much cut) multiply by 100 --> 33.3% decrease. From 12 feet to 8 feet is a 33.3 % decrease. I hope this helps :-)
