Answer:

x/ 12 = 7/3
x = 12*7/3
x = 28 feet
Option A

<u>Consider letter position in names of figures:</u>

A. QR and CD is the correct one

x/ 8 = 7/12
x = 8*7/12
x = 4 2/3

<u>One angle marked and one angle congruent as vertical</u>

A. AA postulate; 4 2/3 is the correct option

A boundary stripe 6 in. wide is painted around a rectangle whose dimensions are 120 ft by 230 ft. Use differentials to approxima

Nimfa-mama [501]

Answer:

350 square feet

Step-by-step explanation:

We are given that

Width of strip=6 in

Dimension of rectangle= $20 ft\times 230 ft$

We know that

Area of rectangle ,A=xy

Differentiate

$dA=\frac{\partial A}{\partial x}x+\frac{\partial A}{\partial y}y$

We have $\frac{\partial A}{\partial x}=y=230 ft$

$\frac{\partial A}{\partial y}=x=120$

$dx=\frac{12}{12}=1 ft$

1 ft=12 in

Because 6 in added in both side of breadth

dy= $\frac{12}{12}=1 ft$

Because 6 in added on both sides of length of rectangle

Substitute the values

$dA=230\times 1+120\times 1=350 ft^2$

Hence, the number of square feet of paint in the strip=350 square feet

How do I find the lateral and total surface area of the prism.

Roman55 [17]

<h3>Explanation:</h3>

<em>Lateral Area</em>

The lateral area is the area of the sides of the prism. If the faces are perpendicular to the bases, then each face is a rectangle. The area of each rectangle is the product of its length and width, generally the product of the height of the prism and the length of one edge of the base.

The total lateral area will then be the product of the height of the prism and the perimeter of the base.

<em>Total Area</em>

The total area is the sum of the lateral area (computed as above) and the area of the two bases of the prism. The formula for that area depends on the shape of the prism. (You have already seen formulas for the areas of triangles, rectangles, and other plane shapes. If not, they are readily available in your text or using a web search.)
