Answer:

Area = 8 square ft

Step-by-step explanation:

Area of a rectangle = Length × width

suppose length = x

width  = y

Here it is given that  x = 3 y - 2

             width is given as y = 2 ft

            ∴ x = 3 × 2 -2

              x = 6 -2

              x = 4

 Area of rectangle = length × width

                              A = 4 × 2

                                 = 8 square ft

Triangles A and B are congruent.<br>Find the area of triangle A. Give your answer to 1 dp.​
Xelga [282]

Answer:

A ≈ 117.3 cm²

Step-by-step explanation:

Pythagorean Theorem: a² + b² = c²

Area of a Triangle: A = 1/2bh

If Triangle A ≅ Triangle B, then the bottom side length of A would be 11 cm and the hypotenuse will stay 24 cm.

Step 1: Find the vertical leg of A

11² + b² = 24²

121 + b² = 576

b² = 455

b = 21.3307 cm

Step 2: Find area of A

A = 1/2(11)(21.3307)

A = 1/2(234.638)

A = 117.319

A ≈ 117.3 cm²

Va box contains 4 red marbles and 7 green remove 3 at once probability of 3 red
lbvjy [14]

Answer:

0.024

Step-by-step explanation:

Given,

Red marbles = 4,

Green marbles = 7,

Total marbles = 4 +7 = 11,

Ways of choosing 3 marbles =^{11}C_3

Ways of choosing 3 red marble = ^4C_3

Hence, the probability of 3 red marble = \frac{^4C_3}{^{11}C_3}

=\frac{\frac{4!}{3!1!}}{\frac{11!}{3!8!}}

=\frac{4}{165}

≈ 0.024
