This is basic Pythagoras. Remember A squared + B squared = C squared?
reverse it and u get c squared - a squared = b squared.
Apply to ur equation. 14.7 squared - 11.9 squared = 216.09 - 141.61 = 74.48 squared. find the square root, 8.630179604156567, and round it to the nearest 10th. That will equal 8.6
Hope it helps!

Answer:
The mid-segment is 17 cm long.
Step-by-step explanation:
The mid-segment of a trapezoid is the average of the bases (mid-segment of a trapezoid theorem), so we can write an equation:
In this case x represents the length of the mid-segment.
The mid-segment is 17 cm long.
Answer:
Continuous.
Step-by-step explanation:
In Mathematics, a random variable can be defined as any variable whose values are determined by the outcome of a random experiment.
Basically, random variables are classified into two (2) main categories and these are;
1. Discrete random variable: a discrete random variable is a data set in which the number of possible values are either finite or countable. For instance, the value of a fair die, number of sweets in a jar, number of eggs in a crate etc.
2. Continuous random variable: a continuous random variable is a data set having infinitely many possible values and those values cannot be counted, meaning they are uncountable. Any quantity such as height, volume, weight, density, length, pressure, temperature, speed, distance, time are generally a continuous random variable.
Hence, the weight of a rock is continuous random variable because it has an infinite number of possible values such as 1kg, 20kg, 10kg, 50kg etc.
I think it is $2.25 unless the calculator is wrong.
Pythagorean theorem you times 40 by 2 then 9 by 2 then square root
