Answer:

The answer to your question is:  60.3°

Step-by-step explanation:

Data

height = 7 m

shadow = 4 m

angle = ?

Process

tangent Ф = opposite side / adjacent side

tangent Ф = 7 / 4

tan Ф = 1.75

     Ф = 60.3°

Square FGNM and its diagonals are shown below. Which pairs of line segments are parallel? Select all that apply.
tiny-mole [99]

Answer:

The parallel sides are:

- FG and MN

- GN and FM

Step-by-step explanation:

The question is incomplete, as the image of the square is not attached.

However, I will answer this question using a general rule.

When a square is named ABCD, it means that AB and DC are parallel sides & BC and AD are also parallel

Using this logic, the parallel sides of FGNM are:

- FG and MN

- GN and FM

The diagonals are:

FN and GM

1.3. If Sara draws a red ball and DOES NOT RETURN it, and then she goes to draw a green
dimulka [17.4K]

Answer:

Dependent Event

Step-by-step explanation:

Assume that are 10 balls, such that:

Red = 6

Green = 4

If the balls are replaced after taken, the probability is:

Pr(Red) = 6/10

Pr(Green) = 4/10

This is referred to as independent event; because each selection do not affect the next or previous selection

However, if the balls are not replaced, the probability is:

Pr(Red) = 6/10

Pr(Green) = 5/(10 - 1) = 5/9

We subtracted 1 because there is a reduction in the number of balls when the red ball is not returned.

This is referred to as independent event; because a selection affects the next selection

Find an equation of the line having the given slope containing the given point slope -9 through (1,-8)
Darya [45]

Answer:

y = - 9x + 1

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

here m = - 9, hence

y = - 9x + c ← is the partial equation

To find c substitute (1 , - 8) into the partial equation

- 8 = - 9 + c ⇒ c = - 8 + 9 = 1

y = - 9x + 1 ← equation of line

Asap plz help maxium points will mark brainliest

Given statement is False, if a light cost $3, it could be either Green or Yellow.

Converse: If the light bulb was Yellow, then the cost was $3 = True

Contrapositive makes both statements negative and switches the order of the original statement.

So something like:  If the light bulb is not yellow, then the cost would not be $3 = False because two colors cost the $3.

Inverse makes both statements negative but keeps the same order.

Something like : If the light bulb did not cost$3 then the light bulb was not yellow = False because two colors cost the $3.
