Rational numbers are a giant group of numbers in mathematics. Basically, rational numbers are all numbers that can be written as a fraction. The set of rational numbers includes many subsets of numbers which are provided in the image.
Answer:
B. 8
Step-by-step explanation:
48/8=6
56/8=7
120+x+16+x=180
2x+ 136=180
2x=44
X= 22
<B= 22
First you have to find the area of the rectangle.
A=Lw
A=91(68)
A=6,188 m
Next you have to find the area of the semi- circles.
A of circle= radius to the second power times pi
A=68x68
A= 4,624
Multiply the area of the semi- circles by 2 since there are two of them. That will give you 9,248 m. Add 9,248 with 6,188 and that will give you your final answer which is 15,436 m.
Answer:
-2 and 5
Step-by-step explanation:
If roots of a quadratic are "a" and "b", then (x-a) and (x-b) are factors. Then the quadratic can be written as ...
y = (x -a)(x -b) = x^2 -(a+b)x +ab
That is, the constant (-10) is the product of the roots, and the x-coefficient (-3) is the opposite of their sum.
In short, you want a solution pair that has a sum of 3. Only one answer qualifies: -2 and 5.
