if k is a half-plane determined by QR, then for every real number 0 < x < or = to 180, there is exactly one ray, QQP, that

zloy xaker [14]

Let me start from the meaning of half plane.you must have learned that there are two axes X and Y axes which includes positive X axes and negative X axes and there is positive Y axes and negative y axes. So there are four quadrants which i have explained in the figure. I have explained the meaning of Half plane in the Diagram also. Half plane=Figure obtained by covering any two adjacent regions of the coordinate axes.So we get four half planes.

Now your question is k is a half plane determined by QR, such that 0<x≤180 and there is exactly one ray QRP that lies in k

So, $0< \angle PQR \leq 180^\cir{0}$

If PQRS is a rectangle, find the length of QT

MAVERICK [17]

Step-by-step explanation:

Since, opposite sides of a rectangle are equal and each angle is of 90°.

$\therefore$ QP = RS = 14 cm

$In \:\triangle QPS, \: \angle QPS = 90\degree$

$\therefore \: QS= \sqrt{QP^2+ PS^2} \\ \therefore \: QS= \sqrt{(14)^2+ (20)^2 } \\ \therefore \: QS= \sqrt{196 + 400} \\ \therefore \: QS= \sqrt{596} \\ \therefore \: QS= 24.41 \: m$

$\because$ Diagonals of a rectangle bisects each other.

$\therefore\: QT = \frac{1}{2} QS\\\therefore\: QT = \frac{1}{2} \times 24.41\\\therefore\: QT =12.205\\\huge\orange {\boxed {\therefore\: QT =12.21\:m}}$

There is a stack of 8 cards each given a different number from 1 to 8. Suppose we select a card randomly from the stack, replace

Alex Ar [27]

Answer:

Step-by-step explanation:

odd numbers are 1,3,5,7

number of odd cards=4

Total number of cards=8

Number of cards less than 4=3 {1,2,3}

$Required~probability=\frac{4}{8} *\frac{3}{8} =\frac{3}{16}$

The sides of a polygon are 3, 5, 4, and 6. The shortest side of a similar polygon is 9. Find the ratio of their perimeters.

Rainbow [258]

The given polygon has a perimeter of 3 + 5 + 4 + 6 = 18
A similar polygon has sides that are 3 times as big ot 9 + 15 + 12 + 18 = 54

The ratio is 18/54 or 1/3
