Answer:
x = 4
Step-by-step explanation:
110ₓ = 40₅ --------- change all to base ten.
<u>the system called binary</u>
1x²+1x ¹+0x⁰ = 45¹+0*5⁰
x² + x + 0 = 20
x² + x – 20 = 0
solve x using Quadratic equation
-1 ±
x = ------------------------------------
2 * 1
x = -5; x = 4
therefore, x = 4

D
Step-by-step explanation:
the mean is the average of the set of numbers, which makes it perfect for summarizing data.
6.9ft
So clearly in this situation the side length of the cloth is the square root of 48, which is 6.928.... closest to 6.9ft
Answer:
No, it is not a right triangle.
Step-by-step explanation:
If the triangle was a right triangle, then the Pythagorean Theorem states that a^2 + b^2 = c^2. Let's test it on this triangle:
13^2 + 14^2 = 365, or c^2. If this is a right triangle, c should equal 15.
However, sqrt(365) = 19.1, which is not 15. So, the triangle is not a right triangle.
