A shadow 12 meters long is cast by a fir tree that is 16 meters tall. What is the length of the shadow cast by a nearby ash tree that that is 8 meters tall?
Write your answer as a whole number or a decimal. Do not round.
Answer: 5 m
Step-by-step explanation:
Given
Length of 16 m fir tree is 12 m
length of the ash tree is 8 m
Suppose x is the length of the ash tree
angle [tex]c[/tex] made by fir and ash tree will be same as shown in figure
[tex]\Rightarrow \tan c=\dfrac{16}{12}=\dfrac{8}{x}\\\\\Rightarrow x=8\times \dfrac{12}{16}\\\\\Rightarrow x=5\ m[/tex]

Find the product 8/6n-4 • (9n^2-4).
An expression can be written in rational form by writing it as a fraction with a denominator of
Answer:
The correct answer is 1 for the first part, and 12n+8 for the second part.
Step-by-step explanation: I got them wrong for you guys. Edge 2021.
The product of the expression given is 12n + 8.
What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
The given expression is ([tex]\frac{8}{6n-4}[/tex]) . (9n² - 4)
Multiplying the numerators together,
([tex]\frac{8}{6n-4}[/tex]) . (9n² - 4) = [8 (9n² - 4)] / [6n - 4]
= {8 [ (3n)² - (2)² ] } / {6n - 4}
We have an algebraic identity, a² - b² = (a + b) (a - b)
Using this identity (3n)² - (2)² = (3n + 2) (3n - 2)
And the expression in the denominator, 6n - 4 = 2 (3n - 2)
([tex]\frac{8}{6n-4}[/tex]) . (9n² - 4) = [8 (3n + 2) (3n - 2)] / [2 (3n - 2)]
The expression 3n - 2 gets cancelled as it lies in both numerator and denominator.
([tex]\frac{8}{6n-4}[/tex]) . (9n² - 4) = [8(3n + 2)] / [2]
= 4 (3n + 2)
= 12n + 8
Hence the product is 12n + 8.

Question 6 of 10
Which equation matches the graph of the greatest integer function given
below?
Answer:
B. y = [x] + 3
Step-by-step explanation:
The answer to this graph would be
B. y = [x] + 3
This is because the graph is translated up by 3 units. Such that a value of 0 passed into x would give us a y value of 3 on the graph, which is represented as a black dot. For a value of -4 passed as x, the largest integer that is less than -4 would be -4 itself and if we add 3 to it due to following this function, we get a y value of -1 which is what is represented in the graph.

Brian and sonya each have a container. They mark their containers to show tenths. Brian and sonya both fill their containers with 0.7 units of juice. However, brian has more juice in him container. Explain how this is possible.
Answer:
Step-by-step explanation:
Brian could have more juice than Sonya in actual sense, This is because the representation used, that is the container has been calibrated to show tenth. This means that decimal values of juice in the container will not show explicit volume beyond tenth. Hence the volume will be rounded.
For instance, if the actual volume of juice Brian has Is 0.74 and that owned by Sonya is 0.69. In actual sense, 0.74 > 0.69 . However, if both pour their juice into the calibrated container, Brian's volume will be rounded to the nearest tenth as 0.7 and Sonya's (0.69) will also be rounded to 0.7.
But in actual sense, Brian has more Juice than Sonya.

Answer:
y - 3 = -1/2(x-1)
Step-by-step explanation:
Given the coordinates (1, 3) and (5,1). The point slope form is expressed as;
y - y0 = m(x-x0)
m is the slope
(x0, y0) is the required point
Get the slope
m = 1-3/5-1
m = -2/4
m = -1/2
Using the point (1,3), substitute
y - 3 = -1/2(x-1)
2(y-3) = -(x-1)
Hence the required equation is y - 3 = -1/2(x-1)
Answer:
y - 3 = -1/2(x-1)

1. If you toss a coin 30 times, you expect the coin lands on the tail _____ times.
Answer:
15 times
Step-by-step explanation:
50% of the time, 50% of 30=15
Answer: 15 times
Step-by-step explanation:
A coin has a 50/50 chance to get either heads or tails. 50% of the time it's heads, 50% is tails. So, if you tossed a coin 30 times, you would expect the coin to land on the tail 15 times because 30 / 2 = 15.

If the circle has a diameter of a team meters in a central angle of 210° what is the area of the sector
Answer:
[tex]Area = 45.82m^2[/tex]
Step-by-step explanation:
Given
[tex]d = 10m[/tex] --- diameter
[tex]\theta = 210^\circ[/tex]
Required
Determine the area of the sector
The ares of the sector is calculated as:
[tex]Area = \frac{\theta}{360} * \pi r^2[/tex]
Where
[tex]r = \frac{d}{2}[/tex]
This gives:
[tex]r = \frac{10m}{2} = 5m[/tex]
So, we have:
[tex]Area = \frac{210}{360} * 3.142 * 5^2[/tex]
[tex]Area = \frac{210}{360} * 78.55[/tex]
[tex]Area = \frac{210 * 78.55}{360}[/tex]
[tex]Area = \frac{16495.5}{360}[/tex]
[tex]Area = 45.82m^2[/tex]
