Answer: A circle.
Step-by-step explanation:
To solve this exercise is important to remember:
- A sphere is a three-dimensional object whose surface is round.
- A cross section is defined as the intersection of a figure with three dimensions and a plane.
- By definition, all the intersects of a sphere an a plane are circles.
Based on the information shown above, you can conclude that the cross section, which is shown in the figure attached, is a circle.
The car was towed for 48 miles.
Step-by-step explanation:
Given,
Amount charges by Acme towing = $30
Per mile charges = $3
Total charged = $174
Let, x be the number of miles.
Towing charges + Per mile charges*number of miles = Total charged
30+3x=174
Subtracting 30 from both sides
Dividing both sides by 3
The car was towed for 48 miles.

Let <em>h</em> represent the cost of hot dogs and <em>p</em> represent the cost of potato chips.
Customer 1: 4h + 5p = 15.50 ⇒ 3(4h + 5p = 15.50) ⇒ 12h + 15p = 46.50
Customer 2: 3h + 2p = 9.00 ⇒ -4(3h + 2p = 9.00) ⇒ <u> -12h - 8p = -36.00</u>
7p = 10.50
p = 1.50
Customer 2: 3h + 2p = 9.00 → 3h + 2(1.50) = 9.00 → 3h + 3.00 = 9.00 → 3h = 6.00 → h = 2.00
Answer: hot dog = $1.50, potato chips = $2.00
With all the money that your family gave you, you would have $150
Following the rules of PEMDAS:
We would do exponents before the division
27 ^ 2 = 729
27 ^ 4 = 531,441
729/531441/3 = 0.000456247 approximately
