Number of grams of cereal A = a
Number of grams of cereal B = b
One gram of Cereal A has: 6 mg of sodium and 7 calories
One gram of Cereal A has: 8 mg of sodium and 5 calories
We need to make sure that the cereal contains maximum 200 mg sodium
⇒ Number of grams of cereal A × Sodium quantity in a gram of cereal A + Number of grams of cereal B × Sodium quantity in a gram of cereal B <= 200 mg
Substituting the required values
⇒ a×6 + b×8 <=200
Further simplifying the above equation
⇒ a×3 + b×4 <=100
Further, we need to make sure that the cereal contains maximum 150 calories
⇒ Number of grams of cereal A × Calories in a gram of cereal A + Number of grams of cereal B × Calories in a gram of cereal B <= 150
⇒ a×7 + b×5 <=150
Hence, the system of inequalities that represents the possible mix is:
a×3 + b×4 <=100 AND a×7 + b×5 <=150
Substitute 8 for x in the function.
y=50(8)=400
He would travel 400 miles
It’s 60 dollars Nd 0.6666 is natural answer with runs out of 2030km
Answer:
2.35 miles
Step-by-step explanation:
Please find the attachment for visual understanding.
We are told that the library is 1.75 miles directly north from the school and the park is 0.6 miles directly south of the school.
To find distance between library and park we will add distance of library from school to the distance of park from school.
Therefore, library is 2.35 miles away from park.
The angle measured from the normal to the mirror will be
.. arctan(14/11.5) ≈ 50.6°
