Answer:
3/8 is smaller than 8/10. Just by comparing the denominators you can decide how big or small the fraction will be. If its a larger number, its a smaller fraction.
Step-by-step explanation:
While there are many quadratic equations using -6 and 5 as roots, the most simple would be the basic (x+6)(x-5)=0, or simplified, x² + x - 30 = 0.
Using these roots, all you have to do is make both sides of the equation and even both sides of the multiplied pre-product to equal 0. If using this format, x has to be equal to -6, and 5.
The sum of adjacent sides is half the perimeter, so is 25 cm. Since the side lengths are consecutive numbers, they are both nearly half of 25 cm. One side is 12 cm, the other is 13 cm.
These lengths, then, are one leg and the hypotenuse of the right triangle that makes up half the parallelogram. The other leg, the altitude, is found using the Pythagorean theorem (or your knowledge of Pythagorean triples). It is
... altitude = √((13 cm)² -(12 cm)²) = √(25 cm²) = 5 cm
The length of the altitude is 5 cm.
18 tens 20 ones= 200 hundreds
NH: UD=0 ; AH: UD<0.
U is a Greek letter but I don't have a Greek keyboard. Both D shapes are subscript. NH stands for null hypothesis, AH is for alternative hypothesis. Just took the test.
