Answer:
x + 15
Step-by-step explanation:
9x + 25 + x + 5 = 180
9x + x + 25 + 5 = 180
10x + 30 = 180
10x = 180 - 30
10x = 150
x = 150÷10
x = 15.

Solution:
Yes , what mathematics say that every real number has at least two factors apart from number 1 and -1.
The number zero has infinite factors.
The number 1 and -1 which is neither prime nor composite has only 1 factor i.e itself.
Prime integers has only two factors one and itself.
Non prime integers has more than two factors.
But when you say a number apart from natural, whole and integers it includes rational ,and irrational and when we combine them The set is called Real number. .So, Yes this statement is true for rational and irrational also.
So, yes Kia is not absolutely true, but if she has written the statement in this form: Apart from 1 and -1 , every number has at least two factors then it would have been a true statement.
Answer:
82.8424 feet
Step-by-step explanation:
The leaf, the base of the tree and the top of the tree form a triangle.
The adjacent cathetus to the 46 degrees angle is 80 feet. The opposite cathetus to the 46 degrees angle is the tree height that we want to know. So, using the relation between the opposite cathetus and the adjacent cathetus (so the tangent of the angle), we can find the tree height (h):
tan(46) = h/80 = 1.0355
h = 80*1.0355 = 82.8424 feet
Answer:
1.92cm
Step-by-step explanation:
Circumference of a circle is computed using the formula:
Where:
r = radius
π = 3.14
Since the radius is the distance of the center of the circle from any point of the circle and the diameter is the measure of a straight line that goes across the center of the circle from one side to the other, radius is half of a diameter. So the diameter = 2r.
We can then use the diameter to solve for the circumference by using the formula"
So we just plug in what we know in the formula:
