Prime number = numbers greater than 1, they only have two factors. 1 and the number itself.
composite number = positive integer, multiplying two smaller positive integers.
prime fact. = finding what the prime numbers are and then multiplying them.
factor tree = pretty self-explanatory. all of the numbers spread out into a way so that you can multiply them. for example, (image attached). hope this helps!!
$3.75
Step-by-step explanation:
times 3.25 by 5 which is 16.25 then do 20 - 16.25
You don't need to understand the construction or why it works. You only need to accept the fact that it does. You can figure out the answers to this question by looking at the picture.
RT is tangent to circle Q -- TRUE. That is the point of the construction.
QT is a radius of circle Q -- TRUE. Q is the center and T is on the circle. A line segment from the center to a point on the circle is a radius.
m∠QSR = 90° -- FALSE. Those points lie on the same line. The measure of the angle is 180°.
QS = QT -- FALSE. S lies inside circle Q, so is closer to the center than T, which lies on the circle. (For some choice of point R, S might lie on the circle, but because this statement is not always true, it must be considered false.)
ΔRTQ is a right triangle -- TRUE. A tangent line is always perpendicular to the radius to the point of tangency. The construction succeeds because RTQ is inscribed in semicircle RTQ (centered at S). Such a triangle is always a right triangle.
60 degrees because vertical angles are congruent if you move line y 5 degrees clockwise then you are adding 5+55=60 and since 1 and 3are congruent 3=60 degrees
