Answer:

x=7

Step-by-step explanation:

9x -5 = 58 since they are vertical angles and vertical angles are equal

9x-5 = 58

Add 5 to each side

9x-5+5 = 58+5

9x = 63

Divide each side by 9

9x/9 = 63/9

x=7

The diameter of the attic is 18ft and its height is 18ft. What's is the volume of the space in the attic
Svet_ta [14]
I attached an image with the complete question.

Answer:
volume of attic = 1526.04 ft³

Explanation:
Volume of cone can be calculated using the following rule:
Volume = \frac{1}{3} * area of base * height
Volume = \frac{1}{3} * π * radius² * height
We are given that:
π = 3.14
radius = 18/2 = 9 ft
height = 18 ft

Substitute in the equation to get the volume as follows:
Volume = \frac{1}{3} * 3.14 * (9)^2 * (18) = 1526.04 ft³

Hope this helps :)

The length of a rectangular computer chip is 22 x 10 cm and the width is 7 x 104 cm. Explain how to
mash [69]

Answer:

area = 160160 inches²

area = 1.6016 × 10⁵ inches²

Step-by-step explanation:

The length of the rectangular computer chip is 22 × 10 cm and the width is 7 × 104 cm .  

The area of the rectangular computer chip is the product of the length and the width.

area = length × width

area = (22 × 10) × (7 × 104)  

area = 220 × 728

area = 160160  inches²

In scientific notation

area = 1.6016 × 10⁵ inches²

160160 is written as 1.6016 × 10⁵ because 1.60160 × 100000 = 1.6016 × 10⁵
