Step-by-step explanation: 43 divided by 25 is 43/25 and that’s not right so the correct answer is 1950 because if you divide 1950 by 25 you get 78 and 78 + 12 = 90

dezoksy [38]

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.

$\text{Area of triangle}=\frac{1}{2}(\text{Base}\times\text{Height})$

$\text{Area of triangle}=\frac{1}{2}(4\text{ in}\times6 \text{in})$

$\text{Area of triangle}=2\text{ in}\times 6 \text{in})$

$\text{Area of triangle}=12 \text{ in}^2$

Therefore, the area of the sail is 12 square inches.

Solve for x and y 9/x-4/y=8

borishaifa [10]

You can solve <span>9/x-4/y=8 for x or for y but NOT at the same time.

Solving for x: </span><span>9/x-4/y=8 Mult all 3 terms by xy to eliminate the fractions.

9(xy)/x - 4xy/y = 8xy => 9y - 4x = 8xy, or 9y = 4x + 8xy = 4x(1+2y)

then 9y = x [ 4(1+2y) ]
9y
therefore x = ------------
4(1+2y)

Solve for y using a similar approach.
