Pemdas? OK so how I would remember it by is "Please Excuse My Dear Aunt Sally"
So.. Parenthesis, Exponent(s), Multiplication, Division, Addition, Subtraction..
Example~~~~~
(
+ 4) ×12÷4 - 1= ? so first do parenthesis and then the exponents then add it to 4 and the divide 12 and 4 and then subtract 1 which is 2.. Then after take two and 13 and multiply which is 26~
Hope this helps! :)
The height should equal to 8m
M<1=m<5= corresponding
m<2=m<6= corresponding
m<3=m<6= alternate interior
m<4=m<5= alternate interior
m<1=m<8= alternate exterior
m<2=m<7= alternate exterior
m<1=m<4= vertical
m<5=m<8= vertical
m<2=m<3= vertical
m<6=m<7= vertical
Answer:
The answer is 512
Step-by-step explanation:
4) 32 x 2=60
5) 64 x 2= 128
6) 128 x 2= 256
7) 256 x 2 = 512
8) answer - 512x2=1,024
Multiply each product by 2!
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.
