Answer:
Triangle 1 - [tex]m\angle A = 58^{\circ}[/tex], hypotenuse = 16
[tex]x \approx 8.479[/tex]
Triangle 2 - [tex]m \angle A = 44^{\circ}[/tex], adjacent leg = 18
[tex]x \approx 17.382[/tex]
Triangle 3 - [tex]m\angle A = 49^{\circ}[/tex], opposite leg = 12
[tex]x \approx 15.900[/tex]
Step-by-step explanation:
Each triangle is solved by means of trigonometric relations:
Triangle 1 - [tex]m\angle A = 58^{\circ}[/tex], hypotenuse = 16
[tex]\cos 58^{\circ} = \frac{x}{16}[/tex]
[tex]x = 16\cdot \cos 58^{\circ}[/tex]
[tex]x \approx 8.479[/tex]
Triangle 2 - [tex]m \angle A = 44^{\circ}[/tex], adjacent leg = 18
[tex]\tan 44^{\circ} = \frac{x}{18}[/tex]
[tex]x = 18\cdot \tan 44^{\circ}[/tex]
[tex]x \approx 17.382[/tex]
Triangle 3 - [tex]m\angle A = 49^{\circ}[/tex], opposite leg = 12
[tex]\sin 49^{\circ} = \frac{12}{x}[/tex]
[tex]x = \frac{12}{\sin 49^{\circ}}[/tex]
[tex]x \approx 15.900[/tex]

A bag contains 9 marbles: 3 are green, 4 are red, and 2 are blue. Teresa chooses a marble at random, and without putting it
back, chooses another one at random. What is the probability that the first marble is blue and the second is green? Write
your answer as a fraction in simplest form.
Answer:
Probability[First marble blue, second is green without replacement] = 1/12
Step-by-step explanation:
Given:
Number of green marble = 3
Number of red marble = 4
Number of blue marble = 2
Total marble = 9 marble
Find:
Probability[First marble blue, second is green without replacement]
Computation:
Probability of an event = Number of favorable outcome / Number of total outcome
Probability[First marble blue] = 2 / 9
Probability[second is green] = 3 / [9-1]
Probability[second is green] = 3 / 8
Probability[First marble blue, second is green without replacement] = Probability[First marble blue] x Probability[second is green]
Probability[First marble blue, second is green without replacement] = [2/9][3/8]
Probability[First marble blue, second is green without replacement] = 6 / 72
Probability[First marble blue, second is green without replacement] = 1/12
Subash is saving to buy a video game that costs $72. He earns $12 per week for doing the dishes and spends $3 on ice-cream. Which equation can be used to find how many weeks it will take him to save enough money for the video game?
Answer:
Correct answer is 'A'
Step-by-step explanation:
so money he save per week = $12 - $3 = $9
Now,
To earn 9$ it takes one week or it can be represented as:
$9 = 1 week
So,
$1 = 1/9 week
$72 = (1/9*$72)weeks
$72 = 8 weeks
therefore it will take 8 weeks to save enough money for the video game

Thanks!
Answer:
1. 180
2. 52
3. 288
Step-by-step explanation:
The area of a rectangle can be found by multiplying the length by the width, so the area of the rectangle is 15 * 12 = 180. The area of a triangle can be found by multiplying the base by the height and divide by 2, so the area of the triangle is [tex]13*\frac{8}{2} = 13 * 4 = 52[/tex]. The area of a parallelogram can be found by multiplying the length and the height, so the area of the parallelogram is 24 * 12 = 288.

Select the graph of y = 3 sin (x + pi/4)
Answer:C
Step-by-step explanation:
just did it
The function y = 3 sin (x + pi/4) has graph B is correct.
We have given that,
y = 3 sin (x + pi/4)
We have determined the graph of the given function
We can determine the graph by using the graphing calculator.
What is the graph sine function?
The angle along the horizontal x-axis, and for each angle, we put the sine of that angle on the vertical y-axis. The result, as seen above, is a smooth curve that varies from +1 to -1.
Therefore option B is correct.

What are Scatter plots?A scatter plot is a collection of points plotted on two axes, horizontal and vertical. Scatter plots are useful in statistics because they illustrate the extent, if any, of correlation between the values of observed quantities or phenomena (called variables).
here,
Since a figure is given, of a scatter plot where the value is distributed from 12 to 24, and the density of the graph at 12 to 14 is more than the rest of the plot and the red arrow marked, the value lies outside the spread and the value is said outliner.

It is estimated that 28.5% of automobile crashes are caused by driver distraction, such as texting. If there are 16,370 automobile crashes in a study, what number would be caused by driver distractions?
Answer:
4665 approx
Step-by-step explanation:
Given data
Total number of crashes= 16,370 automobile crashes
Percentage caused by distraction =28.5%
Let us find the number of crashes caused by distraction
=28.5/100* 16,370
=0.285* 16,370
=4665.45
Hence the number of crashes caused by distraction is 4665 approx
