Irrational because you it’s irra
Answer:
12 square inches.
Step-by-step explanation:
Please consider the complete question.
A model ship has a mast that is 7 inches tall. A right triangular sail goes from the top of the mast to 1 inch from the bottom of the mast. The length of the base of the sail is 4 inches. The height of the sail is along the mast. Find the area of the sail.
The sail will form a right triangle with respect to mast, whose height is 6 inches and base is 4 inches as shown in the diagram.
The area of the sail will be equal to area of triangle.




Therefore, the area of the sail is 12 square inches.
its 7 because 7*7=49 and 49*7=343
so the cube root of 343 would be 7
X + y = 20 --> eqn 1
The second equation would be the mass balance shown below:
(x)(0.40) + y(0.70) = 20(0.52) --> eqn 2
Rearranging eqn 1,x = 20 - ySubstitute this to eqn 2:
(20 - y)(0.40) + y(0.70) = 20(0.52)Solve for y,y = 8 grams Finally, solve for x.x = 20 - 8 = 12 grams
Therefore, Serena needs 12 grams of the 40% solution and 8 grams of the 70% solution.
