Answer: -14 degrees F
Explanation:
Draw a vertical number line. Plot -3 on that line. Then move down 11 units to arrive at -14. Think of it like being in basement level 3 of a building, going down 11 floors, to get to basement level 14.
Answer:
Step-by-step explanation:
A polygon in the plane has rotational symmetry if the figure can be mapped onto itself by rotating between 0 and 360° about it's center.
So, we need to find the number of symmetrical line a regular polygon can have.
Note : A regular polygon with n sides has n lines of symmetry and order of symmetry n.
Then, let n be number of symmetrical line lines
Then,
Smallest angle of rotation about the center for which the polygon will be mapped unto itself is
360 / n
Answer:
Step-by-step explanation:
Remark
I take it you are studying the sine law. If that is so, Then it will be set up as
Formula
x/sin(53) = 7 / sin(44) Multiply both sides by Sin(53)
Solution
Sin(53)x/Sin(53) = 7 sin(53)/Sin(44)
x = 7*Sin(53)/Sin(44)
x = 7 * 0.7986/0.6947
x = 8.0848
Note:
The sine law is always set up by 2 ratios. It consists of the sine of an angle divided by the side opposite = equal to another angle's sine over the side oppose the second angle.
The sine law can also be set up as two ratios side opposite / sin(Angle).
Lets say that:
X = price of each notebook
Y = price of each newspaper
So from the problem statement we can create the following equations:
40 X + 20 Y = 130 --> eqtn 1
8 X + 4 Y = 28 --> eqtn 2
Divide both equations by the lowest coefficient to simplify:
Divide eqtn 1 by 20 => 2 X + Y = 6.5
Divide eqtn 2 by 4=> 2 X + Y = 7
So we can see that although both equations has equal left side, the right side do not match. Hence this problem is impossible to solve.
so the given information describes an impossible situation.
