Answer:

The surface area 76.32 in^2

Step-by-step explanation:

To find the surface area of a square pyramid we have to find the area of the base and the area of the sides and add them together.

Area of the base:

Since the base is a square, all we have to do is multiply 3.6 by 3.6.

3.6 * 3.6 = 12.96

The area of the base is 12.96 in^2

Area of the sides:

Since the sides are triangles, to find the area we have to multiply the length by the height and divide by 2.

3.6 * 8.8 = 31.68

31.68/2 = 15.84

The area of one of the sides is 15.84

Surface Area:

To find the surface area we have to add the area of the base and the area of the 4 sides together.

12.96 + 4(15.84)

12.96 + 63.36 = 76.32

The surface area is 76.32 in^2

Draw a picture to show the product of 4:7 x 3. Then write the product
Hoochie [10]

Answer:

¹²/₇

Step-by-step explanation:

Model ⁴/₇ × 3

Assume that you have three pies, each dived into seven slices.

There are only four slices remaining in each pie, that is, there is ⁴/₇ pie in each pie plate

The picture represents ⁴/₇ × 3.  

Model the product

Now, transfer slices to get as many filled pie plates as possible.

Count the total slices.

You have 12 slices, and each slice represents ⅐ of a pie.

You have ¹²/₇  pie.

∴ ⁴/₇ × 3 = ¹²/₇

The length of the base of a triangle is twice its height. If the area of the triangle is 16 square kilometers, find the height.
ValentinkaMS [17]

Answer:

4

Step-by-step explanation:

Area of a triangle = bh/2

B = 2h

16 = 2h × 2/2

h×2 = 16

2h = 16

* put a square root on both sides then u will get the answer which is

Height of the triangle = 4

A balloon has a circumference of 28 in. Use the circumference to approximate the surface area of the balloon to the nearest squa
Soloha48 [4]
C=2πr

r=C/(2π), now the surface area is:

A=4πr^2, using r found above we have:

A=4πC^2/(4π^2)

A=C^2/π, we are given that C=28 so:

A=28^2/π in^2

A=784/π in^2

A≈250 in^2 (to nearest square inch)

Find the complex zeros of the following polynomial tunction and use the complex zeros to factor f
kramer

Answer:

x = 5 or x = 5 + 2 i or x = 5 - 2 i

Step-by-step explanation:

Solve for x:

x^3 - 15 x^2 + 79 x - 145 = 0

Hint: | Factor the left-hand side.

The left hand side factors into a product with two terms:

(x - 5) (x^2 - 10 x + 29) = 0

Hint: | Find the roots of each term in the product separately.

Split into two equations:

x - 5 = 0 or x^2 - 10 x + 29 = 0

Hint: | Look at the first equation: Solve for x.

Add 5 to both sides:

x = 5 or x^2 - 10 x + 29 = 0

Hint: | Look at the second equation: Solve the quadratic equation by completing the square.

Subtract 29 from both sides:

x = 5 or x^2 - 10 x = -29

Hint: | Take one half of the coefficient of x and square it, then add it to both sides.

Add 25 to both sides:

x = 5 or x^2 - 10 x + 25 = -4

Hint: | Factor the left-hand side.

Write the left hand side as a square:

x = 5 or (x - 5)^2 = -4

Hint: | Eliminate the exponent on the left-hand side.

Take the square root of both sides:

x = 5 or x - 5 = 2 i or x - 5 = -2 i

Hint: | Look at the second equation: Solve for x.

Add 5 to both sides:

x = 5 or x = 5 + 2 i or x - 5 = -2 i

Hint: | Look at the third equation: Solve for x.

Add 5 to both sides:

Answer: x = 5 or x = 5 + 2 i or x = 5 - 2 i
