Answer:

The surface area of the figure is SA=458\ ft^{2}

Step-by-step explanation:

we know that

The surface area of the figure is equal to

SA=2B+PH

where

B is the area of the L-shaped cross section

P is the perimeter of L-shaped cross section

H is the width of the figure

<em>Find the area of the L-shaped cross section</em>

B=12*7+5*5=109\ ft^{2}

<em>Find the perimeter P of L-shaped cross section</em>

P=(12+7+7+5+5+12)=48\ ft

H=5\ ft

substitute

SA=2(109)+(48)(5)=458\ ft^{2}

Answer:

Surface area = 458 square ft

Step-by-step explanation:

From the figure attached with this answer we can see figure.

<u>To find the surface area of the figure</u>

Surface area is sum of area of  small rectangles

Surface area = 2(12 * 7 ) + 4(5 * 5) + 2(12 * 5) + 2(7 * 5)

= 2*84  + 4*25 + 2 *60 + 2*35

 = 168 + 100 + 120 + 70

 = 458

Therefore surface area of given figure = 458 square ft

BARSIC [14]

Answer:

-0.75k - 2.0

Step-by-step explanation:

0.25k + 1.5 − k − 3.5

Combining like terms with rational coefficients

0.25k + 1.5 - k - 3.5

Collect like terms with rational coefficients

=0.25k - k + 1.5 - 3.5

= -0.75k - 2.0

Answer equals negative zero Point seven five k minus two point zero

Suppose the null hypothesis is not rejected. State the conclusion based on the results of the test. Three years​ ago, the mean p
Likurg_2 [28]

Answer:

A. There is not sufficient evidence to conclude that the mean price of a​ single-family home has decreased

Step-by-step explanation:

To study : Whether the mean price of single family home has decreased or not -

Null Hypothesis [H0] = There is no change in mean price of single family home

Alternate Hypothesis [H1] = There is change (decrease) in mean price of single family home

If the null hypothesis is not rejected, it implies that 'there is no change in mean price of single family home' has been statistically accepted.

So, it states that - There is not sufficient evidence to conclude that the mean price of a​ single-family home has decreased
