8 0

<span>Assuming that they all have equal probability, there are seven possibilities in total (0, 1, 2, 3, 4, 5, and 6) so the answer is 1/7

Answer= 1/7

there are 7 number possibilities ex 0,1,2,3,4,5,6

So the odds of randomly generating one number would be 1 in 7 possibilities.

1/7

If DF=78, DE=5x-9, and EF=2x+10, find DE.

Kazeer [188]

Given that E is a point between Point D and F, the numerical value of segment DE is 46.

<h3>What is the numerical value of DE?</h3>

Given the data in the question;

E is a point between point D and F.
Segment DF = 78
Segment DE = 5x - 9
Segment EF = 2x + 10
Numerical value of DE = ?

Since E is a point between point D and F.

Segment DF = Segment DE + Segment EF

78 = 5x - 9 + 2x + 10

78 = 7x + 1

7x = 78 - 1

7x = 77

x = 77/7

x = 11

Hence,

Segment DE = 5x - 9

Segment DE = 5(11) - 9

Segment DE = 55 - 9

Segment DE = 46

Given that E is a point between Point D and F, the numerical value of segment DE is 46.

What’s.the perimeter of a square with an area of 49 cm2

Free_Kalibri [48]

Answer:

Step-by-step explanation:

Area of a square =

$s^2$

Perimeter =

$4\times s$

Where s = side

Solve for s using the area

$A =49\\\\49 = s^2\\\\Square\:root \:both\:sides\:of\:the\:equation\\\\\sqrt{49} = \sqrt{s^2} \\\\7 =s\\\\s =7$

Find the perimeter

$4\times s\\\\= 4 \times 7\\\\= 28$

The angle of depression from the top of a flag pole to a point on the ground is 30°. If the point on the ground is 75 feet from

Cerrena [4.2K]

Answer:

Height of flag pole to the nearest foot is 43 feet

Step-by-step explanation:

In the diagram we have flag pole AB and C is the point on the ground.

It is given that angle of depression is 30°

and the distance of the point C from the base B is 75 feet

so we have

BC= 75 feet

∠C = 30°

AB= h feet

now in right ΔABC

$tan C = \frac{opposite \ side }{base} \\tan C=\frac{AB}{BC}$

now we plug AB= h , ∠C= 30° and BC =75

$tan 30= \frac{h}{75}$

$75 tan30 = h$ ( multiply both sides by 75)

$h= 75 tan 30 =75 (0.5773)\\ h= 43.3 feet\\$

Height of flag pole to the nearest foot is

h= 43 feet
