If there is 1.8g of fat in 100ml,how many will be in 250ml
Answers
Answer 1
Answer:
from 100ml to 250ml is an increase by a factor of 2.5. since the amount of fat is directly proportional to the total amount, the amount of fat should increase by a factor of 2.5 as well. therefore: (1.8)(2.5) = 4.5
Tony’s class needs more than $500 for the school dance. So far, they have raised $200. They plan to have a car wash, charging $8 a car, to raise more money. Tony solved the inequality 8x + 200 Greater-than-or-equal-to 500, and determined that if they wash 37 cars, they will have enough money. Is he correct? Explain.
Answers
no, tony is not correct. solving the inequality tells us that x is greater than or equal to 37.5. since the class must wash a whole number of cars, they need to wash at least 38 cars.
