How much oil must I add to have the correct proportions?
A 10 ml B 30 ml C 40 ml D 80 ml
Answer:
We know that you put (90-50), or 40 ml of lemon juice. If 40 ml of lemon juice is 1/3 of the total sauce, then 80 ml of it should be oil.
So you should add 30 ml more oil to make it proportional.
Let me know if this helps!
24a^4+18=6(4a^4+3)
12a^3+8a=4(3a^3+2a)
16a^5−20a^3=4a^3(4a^2−5)
30a^6−24a^2=3a^2(10a^4−8)
B.) t + b less than or equal to 20 15t + 8b greater than or equal to 150
C.) t + b less than or equal to 20 15t + 8b less than or equal to 150
D.) None of the systems shown represent this scenario.
Answer:
Option B is the correct answer.
Step-by-step explanation:
Earning for tutoring per hour = 15$
Earning for bag boy per hour = 8$
We have Nick is only able to work up to 20 hours per week but must earn at least $150 per week and t represents the number of hours Nick tutors and b represents the number of hours he works as a bag boy.
Nick is only able to work up to 20 hours per week
t + b ≤ 20
But must earn at least $150 per week
15 t + 8 b ≥ 150
Option B is the correct answer.
