A length of rope is stretch between the top edge of the building at stake in the ground the head of the state is at ground level the rope also touches a tree that is growing halfway between the state and the building if the tree is 38 feet tall how tall is the building
Because the tree is the halfway point, the building would be twice as tall:
The building is 38 x 2 = 76 feet tall.
Answer:
76 feet
Step-by-step explanation:
based on the looooooong txt, the building n tree form two similar right-angled triangles w the rope as the hypothesis.
tree is halfway between stake and bldg so stake-to-bldg = 2 x stake-to-tree
as the triangles are similar, their sides are in the same ratio
bldg height = 2 x tree height
= 2 x 38
= 76 feet tall
A ship's sonar finds that the angle of depression to a ship wrack on the bottom of the oceanis 12.5°. If a point on the ocean floor is 60 meters directly below the ship, how many meters is it from that point on the ocean floor to the wreck?
Answer:
The 13.2 meters from that point on the ocean floor to the wreck.
Step-by-step explanation:
As given
A ship's sonar finds that the angle of depression to a ship wrack on the bottom of the ocean is 12.5°.
If a point on the ocean floor is 60 meters.
Now by using the trigonometric identity.
[tex]tan\theta = \frac{Perpendicular}{Base}[/tex]
As shown in the figure given below.
Perpendicular = CB
Base = AC = 60 meters
[tex]\theta = 12.5^{\circ}[/tex]
Put in the identity
[tex]tan\ 12.5^{\circ} = \frac{CB}{AC}[/tex]
[tex]tan\ 12.5^{\circ} = \frac{CB}{60}[/tex]
[tex]tan\ 12.5^{\circ} = 0.22[/tex]
[tex]tan\ 12.5^{\circ} = 0.22[/tex]
[tex]0.22= \frac{CB}{60}[/tex]
CB = 60 × 0.22
CB = 13.2 meters
Therefore the 13.2 meters from that point on the ocean floor to the wreck.
The distance from the point on the ocean floor directly below the ship to the shipwreck is approximately 13.3 meters.
We will use the tangent function, which relates the angle of depression to the opposite side (the distance from the point directly below the ship to the shipwreck) and the adjacent side (the depth of the ocean at the point directly below the ship).
Given:
The angle of depression [tex]\theta[/tex] is [tex]12.5^o.[/tex]
The depth of the ocean at the point directly below the ship, h, is 60 meters.
We want to find the distance from the point directly below the ship to the shipwreck, which we will call [tex]d.[/tex]
Using the tangent function :
[tex]\[ \tan(\theta)[/tex] = [tex][\frac{\text{opposite}}{\text{adjacent}}][/tex]
[tex]\[ \tan(12.5^o) = \frac{d}{60} \][/tex]
To find d, we rearrange the equation: [tex]\[ d = 60 \times \tan(12.5^o) \][/tex]
Now we calculate the tangent of 12.5 and multiply it by 60:[tex]\[ d = 60 \times \tan(12.5^o) \][/tex]
[tex]\[ d \approx 60 \times 0.22169\][/tex]
[tex]\[ d \approx 13.3014 \][/tex]
Therefore, the distance from the point on the ocean floor directly below the ship to the shipwreck is approximately 13.3 meters.
The diagram of question is:
Y is inversy proportional to x. When y=7 , x=9 A) work out an equation connecting y and x? B) work out the value of y when x=21
Answer:
see explanation
Step-by-step explanation:
since y is inversely proportional to x the equation relating them is
y = [tex]\frac{k}{x}[/tex] ← k is the constant of proportionality
to find k use the given condition when y = 7, x = 9
k = yx = 7 × 9 = 63
y = [tex]\frac{63}{x}[/tex] ← is the equation connecting them
when x = 21, then
y = [tex]\frac{63}{21}[/tex] = 3
The equation connecting y and x is y = 9 + 3x. When x = 21, y = 72.
Explanation:The equation connecting y and x is given by y = 9 + 3x. In this equation, the constant term, also known as the y-intercept, is 9. The coefficient of x, also known as the slope, is 3. This means that for every increase of 1 in x, y increases by 3.
To calculate the value of y when x = 21, substitute x = 21 into the equation: y = 9 + 3(21) = 9 + 63 = 72. Therefore, when x = 21, y = 72.

If JK and LM are congruent and parallel, then JKL and MLK are congruent.
Answer:
Given statement is TRUE.
Step-by-step explanation:
Given that line segment JK and LM are parallel. From picture we see that LK is transversal line.
We know that corresponding angles formed by transversal line are congruent.
Hence ∠JKL = ∠ MLK ...(i)
Now consider triangles JKL and MLK
JK = LM {Given}
∠JKL = ∠ MLK { Using (i) }
KL = KL {common sides}
Hence by SAS property of congruency of triangles, ΔJKL and ΔMLK are congruent.

In Sakura's garden, for every 55 red flowers, there are 1010 yellow flowers. There are a total of 7575 yellow and red flowers in her garden. How many red flowers are in Sakura's garden?
Answer:
The answer is 25
Step-by-step explanation:
Therefore, there are 25 red flowers in Sakura’s garden1.
We know that for every 55 red flowers, there are 1010 yellow flowers.
The total number of flowers in the garden is 7575 (which includes both red and yellow flowers).
Let’s use the variable (x) to represent the number of red flowers in the garden. We can set up the following ratio:
[tex][ \frac{{\text{{Red flowers}}}}{{\text{{Total flowers}}}} = \frac{{55}}{{55 + 1010}} ][/tex]
Solving for (x):
[tex][ \frac{{\text{{Red flowers}}}}{{7575}} = \frac{{55}}{{55 + 1010}} ][/tex]
Cross-multiplying:
[tex][ 55 \cdot 7575 = 55x + 1010x ][/tex]
Simplifying:
[tex][ 7575 = 55x + 1010x ][/tex]
Combining like terms:
[tex][ 7575 = 1065x ][/tex]
Solving for (x):
[tex][ x = \frac{{7575}}{{1065}} = 25 ][/tex]
Write the sentence as an inequality. 14 is no less than 8 times a number x plus 6.
Answer:
[tex]x \leq 1[/tex]
Step-by-step explanation:
Multiplying 8 by x can be written as 8x, and +6 on end:
8x + 6
Because it says 14 is no less than, the equal to or more than sign needs to be used:
[tex]8x + 6 \leq 14[/tex]
The -6 can be moved over to the other side making it a -6:
[tex]8x \leq 14 - 6[/tex]
[tex]8x \leq 8[/tex]
Simplify by dividing both sides by 8:
[tex]x \leq 1[/tex]
Which is the inequality!
Answer:
The given statement can be written as [tex]14\geq 8x+6[/tex] or [tex]x\leq 1[/tex].

By simplifying and rearranging the given system of equations, we find that the ordered pair (s, t) that satisfies the system is (2, 1 + 2/3).
Explanation:The system of equations given in the question is:
s/2 - 3t = -1
3t - 2s = 3.
We can begin solving this system by first multiplying the first equation by 2 to eliminate the fraction, giving us:
s - 6t = -2.
Next, we rearrange the second equation to be in terms of 's':
2s = 3t + 3.
We then substitute this into the first equation and solve for 't':
(3t + 3) - 6t = -2,
simplifying to:
-3t + 3 = -2,
leading us to t = 1 + 2/3.
Substituting 't' into the second equation to find 's', we get:
2s = 3(1 + 2/3) + 3, which simplifies to s = 2. Therefore the ordered pair (s,t) that satisfies the system of equations is (2, 1 + 2/3).

A pair of shoes usually sells for $62. If the shoes are 40% off, and sales tax is 8%, what is the total price of the shoes, including tax?
Answer:
45.57
Step-by-step explanation:
Final answer:
After applying a 40% discount to the original $62 price of the shoes and adding an 8% sales tax, the total cost of the pair of shoes is $40.18.
Explanation:
The question involves calculating the total price of a pair of shoes after a discount and adding sales tax. To find the discounted price, we take 40% off the original price of $62. To calculate 40% of $62, we multiply 62 by 0.40 (which is 40% as a decimal), giving us $24.80. We subtract this discount from the original price: $62 - $24.80 = $37.20, which is the discounted price of the shoes.
Next, calculate the sales tax on the discounted price by converting the sales tax rate from a percent to a decimal. The sales tax rate is 8%, which as a decimal is 0.08. Multiply the discounted price by the sales tax rate: $37.20 x 0.08 = $2.976, which we round to $2.98.
Finally, add the sales tax to the discounted price to find the total cost: $37.20 + $2.98 = $40.18. Therefore, the total price of the shoes, including tax, is $40.18.

Answer:
Look at your answer choices and see which one has multiplied each of the shots by 2
Step-by-step explanation:
Step-by-step explanation:
To find the right matrix, you have to look which matrix among the options has doubled each item.For example, if you have:
[tex]\left[\begin{array}{ccc}1&2&3\\4&5&6\\7&8&9\end{array}\right][/tex]
Then, your answer would be:
[tex]\left[\begin{array}{ccc}2&4&6\\8&10&12\\14&16&18\end{array}\right][/tex]
Because each term is the double of the original matrix.
Remember that, this operation is between a scalar and a matrix. That operation is done according to this property:[tex]aM=a\left[\begin{array}{ccc}1&2&3\\4&5&6\\7&8&9\end{array}\right] = \left[\begin{array}{ccc}1a&2a&3a\\4a&5a&6a\\7a&8a&9a\end{array}\right][/tex]

How to solve this problem?
Answer:
Can not be determined.
Step-by-step explanation:
We can easily notice that the limit is x tends to infinity, whereas x is not present in the given function, we are given (1 + 1/n). So we can not evaluate the given limit for x as parameter, we must have some function of x to solve this problem.
Hence, option C is correct i.e. the limit can not be determined.
Answer:
cannot be determined
Step-by-step explanation:
If we have, [tex]\lim_{n \to \infty} {1+\frac{1}{n}}[/tex]
We plug in infinity for n directly
1/∞ =0
So when we plug in infinity for n then 1/n becomes 0
[tex]\lim_{n \to \infty} {1+\frac{1}{n}}[/tex]
[tex] {1+\frac{1}{infinity}}[/tex]
1+ 0 = 1
In our problem , limit says x-> ∞
there is no x term inside
[tex]\lim_{x \to \infty} {1+\frac{1}{n}}[/tex]
so we can clearly say limit cannot be determined
