Given triangle HJK and triangle RST, what is
tan(R)?
Answer:
B) [tex]\frac{5}{12}[/tex]
Step-by-step explanation:
Tan= Opposite/Adjacent
HJK = RST
Tan H = Tan R
Tan H = 5 (Opposite) / 12 (Adjacent)
So...
Tan R= 5/12

Find the surface area of the pyramid. The side lengths of the base are equal.
__________
If you cant see the numbers
* Bottom number is 13m and the one with an arrow is 18 m
Again sorry if you cant see it
Answer: 637 m²
Step-by-step explanation:
We need to find the area of four triangles and one square.
The square: 169 m²
A = L²
A = (13 m)²
A = 169 m²
The triangles: 468 m²
-> We have four congruent triangles. I will find the area of two (skipping the "divide by two" part of the formula) and multiply by two to find all four at once.
A = B * H
A = (13 m) * (18 m)
A = 234 m²
-
234 m² * 2 = 468 m²
Total surface area:
169 m² + 468 m² = 637 m²

If you roll two fair six -sided dice, what is the probability that the sum is 5 or lower?
Answer:
The probability that the sum is 5 or lower for each dice when rolled is 25/36, since all numbers equal to or below 5 count. Since there are 5 numbers out 6 possible, 5/6 is the probability fo rolling 5 or lower for one. Multiply 5/6 by itself, since we are rolling twice 5/6 * 5/6 = 25/36 or about a 69.5% chance

A plastic container holds 3 red balls, 2 green balls, and 3 yellow balls. What is the probability of choosing a green ball, replacing it, and then choosing a yellow ball?
Answer:
[tex]0.09375[/tex]
Step-by-step explanation:
the total number of balls = 3 + 3 + 2 = 8
Let p be the probability of choosing a green ball, replacing it, and then choosing a yellow ball.
[tex]p=p\left( \text{choosing a green ball} \right) +p\left( \text{choosing a yellow ball} \right)[/tex]
[tex]=\frac{2}{8} \times \frac{3}{8}[/tex]

Which number set correctly represents the range of the given data? {(0, 0), (2, 0), (3, 0), (5, 0)} {0, 2, 3, 5} {0, 2, 3} {0, 2} {0}
{0}
Step-by-step explanation:The range of a function is the set of y-values within a function.
Finding the Range
As stated above, the range is all of the y-values. To find the y-values remember that in a coordinate pair the second point is the y-value. So, look at the second value of each pair. For all 4 points, the y-value is 0. This means that the range is 0.
Range Notation
Now that we know the range, we need to use the correct notation. When writing domain or range, make sure that the values are listed in order from least to greatest. Additionally, even if y-values repeat in the coordinate pairs, only state them once in the range. In this case, there is only 1 unique value, so the range should only have 1 value. Finally, the range is surrounded by braces. Therefore, the range should be written as {0}.
Find the GCF of 2y²z and 8yz²
Answer:
GCF(2y²z , 8yz²) = 2yz
Step-by-step explanation:
2y²z = (2yz) × y
8yz² = (2yz) × 4z
then
GCF(2y²z , 8yz²) = 2yz
(05.02) Find the measure of angle x in the figure below:
55
45
80
55
100
To find x, first find y.
In a triangle, all the angles add up to 180. So we can create the equation:
45+55+y=180
100+y=180
y=80
Since x and y are vertical angles, that mean they are equal so that means angle x is also 80.

How many seconds will it take an echo to reach your ears if you yell toward a mountain
92.0 m away on a day when the air temperature is 0°C?
O 0.556 s
O 1.80 s
0 3.60 s
O 0.277 s
It will take 0.556 seconds for an echo to reach one's ears
Calculating the time to hear an echoFrom the question, we are to determine how long it would take an echo to reach one's ears
From the formula,
[tex]Speed = \frac{2 \times distance \ travelled\ by \ sound}{Time}[/tex]
NOTE: To hear an echo, the sound will travel to and fro, hence, it will cover twice the distance
From the given information,
Distance = 92.0 m
NOTE: Speed of sound in air at 0 °C ≅ 331 m/s
Putting the parameters into the formula, we get
[tex]331 = \frac{2 \times 92.0}{Time}[/tex]
[tex]Time = \frac{2 \times 92.0}{331}[/tex]
Time = 0.556 secs
Hence, it will take 0.556 seconds for an echo to reach one's ears.

what is the zero of this function?
Answer:
A. x = 5 and x = 6
Step-by-step explanation:
What are zeroes?
Zeroes are simply the x intercepts of a function or the coordinates where the function crosses the x axis
Finding the zeroes.
By looking at the graph, we can say that the function crosses the x axis at (5,0) and (6,0).
This means the x intercepts / zeroes are at x = 5 and x = 6 so the answer is A

Answer:
[tex]y = -\frac{3}{4} sin(\frac{2}{3}x)[/tex]
Step-by-step explanation:
First determine whether it is a sine function or a cosine function. Since
sin(x) = 0 at x = 0 and we see indeed that the value of the function is 0 at x = 0 it must be a sine function
The general equation of a sine function is [tex]a sinbx[/tex]
where a is the amplitude. The amplitude is one-half the difference between the lowest and highest values in the graph.From the graph we can see that the highest value is 3/4 and lowest is -3/4 so the amplitude = 1/2 (3/4 + 3/4) = 3/4
If the amplitude were positive, the function would be increasing at (0,0) and going up to its amplitude value. However we can see that the function is decreasing at (0,0 ) and goes down to -3/4. Therefore the amplitude a has a negative sign so a = -3/4
To compute b, note that the period of the function ie where it finishes a full cycle is 3π since the function at that x value repeats itself. The relationship between b and the period is 2π/b = 3π in this particular case
This gives b = 2/3
So a = -3/4, b = 2/3 and the equation is [tex]y = -\frac{3}{4} sin(\frac{2}{3}x)[/tex]

Answer:
y = 1.8x, where time is the independent variable, x, and distance is the dependent variable.
Step-by-step explanation:
The independent variable is along the x-axis.
The dependent variable is along the y-axis.
Therefore,
Independent variable = time (in minutes)Dependent variable = distance (in km)Equation of the line
To find the equation of the line, define two points on the line:
Let (x₁, y₁) = (0, 0)Let (x, y₂) = (5, 9)Use the slope formula to find the slope (m) of the line:
[tex]\implies \textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{9-0}{5-0}=1.8[/tex]
From inspection of the graph, the y-intercept is at (0, 0).
Point-slope form of a linear equation: [tex]y = mx + b[/tex]
Substitute the found slope and y-intercept into the formula to create the equation of the line:
[tex]\implies y=1.8x+0[/tex]
[tex]\implies y=1.8x[/tex]
Conclusion
y = 1.8x, where time is the independent variable, x, and distance is the dependent variable.
