there are 9 cards left
1,2,3,4,6,7,8,9,10
the only cards that will make the sum less than 8 is 1 and 2
2/9
Answer: 2/9
A regular decagon has 10 equal sides. An apothem is a perpendicular bisector to the side. This means 2 equal right triangle are formed on each side (20 equal right triangles) or 10 equal isosceles triangles.
Using the 10 equal isosceles triangles and A = .5(base)(height)
Base is a side and height is apothem
Area of regular decagon = 10 × .5 × 8 × 12.3 = 492.0 yd²
Answer: 492.0 yd²
Yes, i am pretty sure! hope it helped!

Answer:
Rational number
Step-by-step explanation:
Any number that can be written as a ratio of two integers is a rational number.
In the question, you have the keyword 'ratio', meaning a comparison between two numbers. For example 1.5 can be expressed as the ratio between 3 and 2 (3/2), as a fraction.
<u>When a number cannot be expressed as a fraction, it's called an irrational </u>number. <u> The most famous irrational number of all would be pi (π). </u> You cannot express pi in a ratio between numbers, because it's too complicated, it's basically an infinite number without any periodicity.
