The semicircle is 25pi or 78.54

The rectangle is 120 (12*10)

The triangle is 24 (.5*12*4)

So the total is 222.54 (78.54+120+24)

You roll a fair 6 sided dice. What is p(not 5)?

liq [111]

Answer:

p(not 5) = 5/6

Step-by-step explanation:

The probability that we roll a 5 is 1/6. So, the probability we don't roll a five is simple 1 minus that:

$1-\frac{1}{6} = \frac{5}{6}$

And that's your answer.

Answer:

2 1/10

Steps:

You need both fractions to have the same denominator, you get 6/10 and 5/10

Subtract your fraction:

6/10 - 5/10 = 1/10

Then your whole numbers:

3 - 1 = 2

Then put your answers together:

2 1/10

A palm tree is supported by two guy wires as shown in the diagram below. Which trig expression can be used to find the height on

Volgvan

Answer:

D. $tan(30^\circ+45^\circ)$ is the correct answer.

Step-by-step explanation:

The given situation can be represented as a figure attached in answer area.

B is the base of tree.

C is the base of wires.

A and D are the end of 2 wires supporting the tree.

$\angle DCB =45^\circ\\\angle ACB =75^\circ\\$

Here, we need to find the Height of the tree which is represented the by side AB.

and we are given that bases of wires and tree base are at a distance 4 ft.

i.e. side BC = 4 ft

If we look at the $\triangle ABC$ , we are given the base BC and the $\angle ACB$ , and the perpendicular is to be find out.

We can use trigonometric identity:

$tan\theta =\dfrac{Perpendicular}{Base}$

$tan 75^\circ = \dfrac{AB}{BC}\\\bold {tan (45+30)^\circ }= \dfrac{AB}{4}\\\Rightarrow AB = \bold {tan (45+30)^\circ } \times 4 = 14.93\ ft$

Hence, D. $tan(30^\circ+45^\circ)$ is the correct answer.
