Answer:
Cereal A is cheaper by $0.15
Step-by-step explanation:
Cost of a 10-ounce box of Cereal A = $2.70
So,
Cost of a 1-ounce box of Cereal A = 
Cost of a 15-ounce box of Cereal A = 
Also,
Cost of a 13-ounce box of Cereal B = $3.64
So,
Cost of a 1-ounce box of Cereal B = 
Cost of a 15-ounce box of Cereal B = 
Here,
Cost of a 15-ounce box of Cereal B - Cost of a 15-ounce box of Cereal A = 
Therefore,
Cereal A is cheaper by $0.15
The answer is f(x) as x^4 has minimum value of 0 so x^4-2 has a minimum of -2
whereas in g(x) x^3 has a minimum of - infinity so g(x) also has minimum of - infinity. hope it helps
X = 20
This is an isosceles triangle so third angle is also 2x because of symmetry.
Angle sum = 5x + 2x + 2x = 9x = 180 degrees
Answer:
24.4 feet
Explanation:
Let x be the length of the wooden board as shown in the diagram.
Using trigonometry ratio, we can write
cross multiplying we get:
Diving through by 0.819, we obtain
To the nearest tenth, x=24.4 feet.
Answer:
because the length is 4 feet more than the width
=> the length is x + 4 (feet)
because the base has an area of 21 square feet
=> x(x + 4) = 21
<=> x² + 4x = 21
