Find The Surface Area Of A Square Pyramid With Side Length 5 Ft And Slant Height 7 Ft.5 Ft5 Ft

Answers

Answer 1

Answer:

99.33ft^2

Step-by-step explanation:

The surface area of a square pyramid is expressed as;

TSA = a²+2a√a²/4 + h²

Given that

a = 5ft

h = 7ft

Substitute

TSA = 5²+2(5)√5²/4 + 7²

TSA = 25+10√25/4 + 49

TSA = 25 + 10√(221/4)

TSA = 25 + 10(√55.25)

TSA = 25 + 10(7.433)

TSA = 25 +  74.33

TSA = 99.33ft^2

Hence the surface area of a square pyramid with side length 5 ft and slant height 7 ft is 99.33ft^2

Answer 2

Answer:5x5=25 fts

4(1/2 x 5ft x7 ft) = 70 fts

Add them up and you get

Answer= 95fts

Answer:

The equation is:

y = -15*x + 1200

and:

a = 120

b = 70

c = -1500

Step-by-step explanation:

This seems to be a linear relationship.

A linear relationship can be written as:

y = a*x + b

where a is the slope and b is the y-axis intercept.

For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:

a = (y2 - y1)/(x2 - x1).

Here we know that our line passes through the points (60, 300) and (20, 900)

Then the slope of this line is:

a = (900 - 300)/(20 - 60) = 600/(-40) = -15

Then this line is something like:

y = -15*x + b

To find the value of b, we know that this line passes through the point (60, 300) then when x = 60, we have y = 300.

Replacing these values in the above equation we get:

300 = -15*60 + b

300 + 15*60 = b = 1200

Then:

y = -15*x + 1200.

Now that we have this equation, we can complete the table.

a is the value for y, when x = 72

Then we can replace x by 72 in the above equation:

a = -15*72 + 1200 = 120

a = 120

b is the value of x when y = 150, then we need to replace y by 150

150 = -15*b + 1200

150 - 1200 = -15*b

(150 - 1200)/-15 = b = 70

then:

b = 70

c is the value of y when x = 180, then we need to replace x by 180.

c = -15*180 + 1200

c = -1500

using angle sum property

we get

110+35+(x+12)=180

(x+12)=180-145

(x+12)= 35

x= 35-12

x= 23

Answer:

Angles in a triangle are sum up to 180 degrees.

35 + 110 + (x+12)=180

145+x+12=180

157+x=180

x=180-157

x=23 degrees

Model With Mathematics A photographer is
placing photos in a mat for a gallery show.
Each mat she uses is x in, wide on each side.
The total area of each photo and mat is
shown

Answers

Answer:

a. The possible dimensions of the total area are;

The width of the total area is (2·x + 8) inches

The length of the total area is (2·x + 10) inches

b. The dimensions of the photos are as follows;

The length of the photos are 10 inches

The width of the photos are 8 inches

Step-by-step explanation:

a. Given that the area, A = 4·x² + 36·x + 80

We get;

A = 4 × (x² + 9·x + 20) = 4 × (x + 4) × (x + 5) = (2·x + 8)·(2·x + 10)

Therefore, the possible dimensions of the total area (photo + mat) are;

The width of the total area (photo + mat) = (2·x + 8) in.

The length of the total area (photo + mat) = (2·x + 10) in.

b. The dimensions of the photos alone are shorter than the dimensions of the photo and mat combined by 2·x each

Therefore, we have the dimensions of the photos are as follows;

The length of the photo = (2·x + 10) in. - 2·x in. = 10 in.

The width of the photos = (2·x + 8) in. - 2·x in. = 8 in.
