What is area of this shape

german

Answer:

132 ft squared

Step-by-step explanation:

One way is to divide the shape into a rectangle and a triangle, by drawing a vertical line.

This gives a rectangle that is 9 by 11, so has area 99.

The triangle has a base of 11 and height of 15 - 9 = 6.

So the area of the triangle = 1/2 x b x h = 1/2 x 11 x 6 = 33

So the total area is 99 + 33 = 132.

Calculate the specific heat of a metal (in calories/gram-degree C) from the following data. A container made of the metal has a

Arisa [49]

Answer:

<h2>The specific heat of the metal is 0.274951 calories/gram-degree C.</h2>

Step-by-step explanation:

Let, the specific heat of the container is x calories/gram-degree C.

The container and water gains (18 - 15) = 3 degrees C.

Hence, the transfer of heat is $3(18.1\times1000\times1) + 3(3.77x\times1000)$ .

The metal, which is dropped in the water, losses (164 - 18)= 144 degrees C.

Hence, the transfer of heat is $144\times 1.45\times1000x$ .

As per the given conditions,

$3(18.1\times1000) + 3(3.77x\times1000) = 144\times1.45\times1000x\\54.3 + 11.31x = 208.8x\\197.49x = 54.3\\x = 0.274951$ .

What is the area of the trapezoid with height 13 units? Enter your answer in the box. units2 A rectangle with a length of 15 and

jolli1 [7]

Answer:

Step-by-step explanation:

Area of the trapezoid = area of rectangle + 2 * area of triangle

Area of a triangle = 1/2 bh

= 1/2 * 13 * 7

= 45.5 units²

Area of a rectangle = L × B

= 15 × 13

= 195 units²

Area of the trapezoid = [195 + 2 * (45.5)]

= 195 + 91

= 286 units²
