<h2><em><u>Answer:</u></em></h2>

Total Surface Area = 375 ft^2

<h2><em><u>Step-by-step explanation:</u></em></h2>

You need to find the area of the ceiling, floor, the two rectangle walls and the two trapezoid walls

<u>Area of the ceiling:</u>

c = length * width

c = 9*6.5 = 58.5

<u>Area of the 2 rectangle walls:</u>

w = 2(length * width)

w = 2(9 * 8)

w = 2(72)

w = 144

<u>Area of floor:</u>

f = 9 * 7.5

f = 67.5

<u>Area of the two trapezoids:</u>

t = 2(h * \frac{a + b}{2})

a = 6.5

b = 7.5

h = 7.5

t = 2(h * \frac{a + b}{2})

t = 2(7.5 * \frac{6.5 + 7.5}{2})

t = 2(7.5 * \frac{14}{2})

t = 2(7.5 * 7)

t = 2(52.5)

t = 105

Total Surface Area = c + w + f + t

Total Surface Area = 58.5 + 144 + 67.5 + 105

Total Surface Area = 375 ft^2

Lynn was shopping and found a purse that was marked with a discount of 1/3 off if the original cost of the purse was $80 how muc
sdas [7]

The amount paid by Lynn is $ 53.33

<em><u>Solution:</u></em>

Given that, Lynn was shopping and found a purse that was marked with a discount of \frac{1}{3} off

Original cost of purse = $ 80

<em><u>To find: Amount paid by Lynn</u></em>

Discount = \frac{1}{3} \text{ of original price }

Therefore, discount price is given as:

\text{ Discount } = \frac{1}{3} \times 80 = 26.67

Thus discount price = $ 26.67

<em><u>Amount paid by Lynn:</u></em>

Amount paid = original price - discount price

Amount paid = 80 - 26.67 = 53.33

Thus amount paid by Lynn is $ 53.33

A transformation of ΔDEF results in ΔD'E'F'.
sladkih [1.3K]

Answer:

Rotation

Step-by-step explanation:

A transformation of a triangle can be either dilation or reflection or rotation or a translation.

Dilation happens when a symmetric figure is formed with scale factor other than 1.  But here both triangles have same side length.  Hence no dilation

Reflection happens when it is reflected over a line as we see in a mirror. But here the two triangles are not looking as images on  a line.  Hence no reflection

Rotation is keeping the same shape but rotating through a certain angle.  Here DEF is rotated without disturbing its shape or size through a certain angle. Hence rotation is right

Translation is not right because there is no vertical or horizontal shift to get new triangle.
