7 of the sweets in the bag are strawberry. Since there are 20 sweets total in the bag, 20 - 7 = 13 sweets in the bag must be non-strawberry.

The probability that a sweet taken at random from the bag is not strawberry would thus be 13/20.

the angle of elevation from a viewer to the top of a flagpole is 50°. the viewer is 40 ft away and the viewers eyes are 5.5 ft f

Margarita [4]

Answer:

53.2 feet

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

In the right triangle ABC

$tan(50^o)=\frac{AC}{BC}$ -----> by TOA (opposite side divided by the adjacent side)

substitute the values

$tan(50^o)=\frac{h}{40}$

solve for h

$h=(40)tan(50^o)$

$h=47.7\ ft$

therefore

The height of the pole is

$h+5.5=47.7+5.5=53.2\ ft$

Can someone help me prove this is a square? Please show all necessary work I paid a lot for this question

kolezko [41]

Answer:

$ab = \sqrt{{2}^{2} + {6}^{2}} \\ ad = \sqrt{{2}^{2} + {6}^{2}} \\ bc = \sqrt{{2}^{2} + {6}^{2}} \\ cd = \sqrt{{2}^{2} + {6}^{2}} \\$

AB=AD=BC=CD => ABCD is square

ZX is √b²+a²

Step-by-step explanation:

From the diagram you notice that length WX is a and length WZ is b.ZX is the diagonal length formed by triangle ZWX.Apply the Pythagorean relationship here the sum of squares of the two sides equals the square of the diagonal.Hence;

ZW²+ WX²=ZX²

b²+a²=ZX²

√b²+a²=ZX
