Answer:
0.9
Step-by-step explanation:
To find the mean temperature, we have to add all of the numbers together and divide that by the amount of numbers there are.
6 + 5 + 3 + -4 + 3 + -3 + 2 + -1 + -2 + 0 = 9
There are 10 numbers.
Our mean, or average, would be 9 / 10 = 0.9
X would be 60, I don’t know an equation, but you can divide both sides by 4 and get 20% of c is 12, and then you can multiply both sides by 5 to get that 100% of x is 60, hope this helps!
If I’m correct he earned $3 per hour mowing lawns. How I got this is because I divided 15 by 5 and thts how I got 3. Hope this helps :)
Answer:
It is the hypotenuse of a right triangle with legs 5 and 12.
Step-by-step explanation:
The diagonals of a parallelogram bisect each other. If the angle at which they meet is a right angle, then a right triangle is formed whose legs are half the length of each of the diagonals, and whose hypotenuse is the length of one side of the parallelogram (rhombus).
Here, the triangle's leg lengths are 5 and 12, so the Pythagorean theorem tells us the hypotenuse is ...
√(5²+12²) = √(25+144) = √169 = 13
Since the perpendicular diagonals are 10 and 24 inches long, the side length of the rhombus must be 13 inches long.
HK must be 13 inches because the Pythagorean theorem applies and that's what it says.
