Final answer:
To find the length of the shadow cast by a 35-foot building with a 60° angle of elevation to the sun, we can use trigonometry. The shadow is approximately 60.6 feet long.
Explanation:
To find the length of the shadow, we can use the concept of trigonometry. In a right triangle, the opposite side is proportional to the shadow length and the adjacent side is proportional to the height of the building. Using the angle of elevation of 60° and the height of the building as 35 feet, we can set up the trigonometric equation as follows:
tan(60°) = x/35
Solving for x, we get x = 35 * tan(60°) = 60.6 feet. Therefore, the shadow is approximately 60.6 feet long to the nearest tenth of a foot.
lin measured the diameter of a circle in two different directions. Measuring vertically, she got 3.5 cm, and measuring horizontally, she got 3.6 cm. Explain sone possible reasons why these measurements differ.
Answer:
Diameter of circle while measuring vertically=3.5 cm
Diameter of circle while measuring Horizontally=3.6 cm
As you have not written by which instrument from geometry box you have measured the length of diameter.
1. By Scale i.e ruler 2. By Divider Or 3. By mere Observation i.e by comparing length
1.If you have done measurement by simply observation there are maximum possibility of having error.
2. Then if you have measured these lengths by scale or ruler there is very less chances of getting error in measurement of length because sometimes divison in scale varies i.e if a point lies between 4.5 to 4.6 we can't say exactly whether it is 4.5 or 4.6.
3. So it is better to compare line segments by Divider.There is no chances of getting error.
Most probably you have measured Diameter by ruler, Due to that you have faced the problem.
Answer:
The possible reasons are shown below:
The shape is not a perfect circle as it is difficult to draw a perfect circle.Measurements could be rounded, not exact.It may be possible that the thickness of the circle affected the measurement.The length of vertical measurement is small, so may be she did't measure across the widest part when she is measuring vertically.Step-by-step explanation:
Consider the provided information.
lin measured the diameter of a circle in two different directions. Measuring vertically, she got 3.5 cm, and measuring horizontally, she got 3.6 cm.
The diameters of a circle should have the same length, If the length are not same then the reasons can be:
The shape is not a perfect circle as it is difficult to draw a perfect circle.Measurements could be rounded, not exact.It may be possible that the thickness of the circle affected the measurement.The length of vertical measurement is small, so may be she did't measure across the widest part when she is measuring vertically.A function is defined as {(0, 1), (2, 3), (5, 8), (7, 2)}. Isaac is asked to create one more ordered pair for the function. Which ordered pair can he add to the set to keep it a function? please help.
1) (0, 2)
2) (1, 3)
3) (5, 3)
4) (7, 0)
Correct answer is option(2).
Isaac can add the ordered pair (1, 3) to the set to keep it a function.
A function is a relation where each input (or domain element) is associated with exactly one output (or range element).
This means that in the set of ordered pairs representing a function, no two pairs can have the same first element (input) but different second elements (outputs).
Given the function defined as : {(0,1),(2,3),(5,8),(7,2)},
we need to add one more ordered pair without violating the property that each input maps to exactly one output.
Let's examine each option:
1.) (0, 2) : This pair has the same first element as (0, 1). Adding (0, 2) would imply that the input 0 maps to both 1 and 2, which is not allowed in a function because each input must map to exactly one output.
2.) (1, 3) : This pair has a first element of 1, which is not present in the original set of ordered pairs. Therefore, adding (1, 3) does not create any conflicts. The input 1 is not repeated, so each input still maps to exactly one output. This maintains the function property.
3.) (5, 3) : This pair has the same first element as (5, 8). Adding (5, 3) would imply that the input 5 maps to both 8 and 3, which violates the definition of a function.
4.) (7, 0) : This pair has the same first element as (7, 2). Adding (7, 0) would imply that the input 7 maps to both 2 and 0, which also violates the definition of a function.
Therfore , Only the pair (1,3) can be added to the set without violating the function property. This pair introduces a new input that does not conflict with the existing inputs in the set.

A student works no more than 25 hours each week at a part-time job. Write an inequality that represents how many hours the student can work each day. (how do you solve this)
Given that a student works no more than 25 hours per week, and that work is performed every day of a 7-day week, the maximum number of hours they can work per day is approximately 3.57, making it fair to say they can work up to 3 hours each day. This scenario can be represented by the inequality h ≤ 3.
Explanation:To answer your question, we need to find an inequality that represents how many hours the student can work each day given they work no more than 25 hours every week.
If we assume a typical week encompasses 7 days, and the student works every day of the week, then we should distribute the maximum hours worked per week over these seven days.
This results in 25 hours ÷ 7 days ≈ 3.57 hours/day. However, since you can't work a fraction of an hour, the student can work up to 3 hours a day.
The inequality representing this scenario would be h ≤ 3, where 'h' represents the number of hours the student can work each day.

Which of the following is NOT true about unit rates?
A.
A unit rate relates a quantity to 1.
B.
Unit rates can be used to compare two rates.
C.
Any rate is equivalent to its unit rate.
D.
A unit rate always relates quantities with the same units.
Answer:
The answer is 4) A unit rate always relates quantities with the same units.
Step-by-step explanation:
It cannot be 1 because a unit rate relates a quantity to 1. Hence the word unit which means single or undivided whole.
It cannot be 2 because you can indeed use unit rates to compare two rates. In fact we do all the time in math! Just like comparing fractions.
It cannot be 3 because the rate has to be equivalent to its unit rate or else its wrong.
Thus making it four!
Hope this helped! If it did please consider marking this as brainliest! :)
Option D is not true about unit rates.
Unit rate is simply a rate that has the denominator as 1. For example, if we want to write the rate at which water is poured per sec. If the speed is 7 m/s, then we can say the rate is 7m per 1 second. Option A; This statement is true because as seen in the speed rate earlier explained, unit rate relates a quantity to one because it only has its denominator as one. Option B: Statement is true because unit rates of similar units are often compared with each other. For example if we want to know which person has a higher speed every second while running a race. Option C: This statement is correct because like said in option B explanation above, unit rates must have same units otherwise, it is no longer a unit rate as different units could lead to different unit rates.Option D: This statement is not correct because unit rates does not always relate quantities with same units.Read more at; brainly.com/question/8406966

your friend says the sum of two linear expressions is always a linear expression. is your friend correct? explain.
Final answer:
The statement that the sum of two linear expressions is always a linear expression is correct, due to properties such as additivity and commutativity. Adding like terms and constants of two linear expressions together will yield another linear expression. This principle applies to linear equations and functions as well.
Explanation:
Your friend's assertion that the sum of two linear expressions is always a linear expression is correct. A linear expression is generally of the form αx + β, where α and β are constants and x is the variable. When adding two linear expressions, say αx + β and γx + δ, the result is (α+γ)x + (β+δ), which is also a linear expression. This is due to the additive property, which states that like terms can be added and constants can be added separately. Also, considering the commutative property of addition, which implies A+B = B+A, we can see that the order of addition does not affect the linearity of the expression.
Examples or specific cases also illustrate this concept. For instance, if one linear expression is 3x + 2 and the other is 5x + 4, adding them together yields (3+5)x + (2+4), which simplifies to 8x + 6, clearly a linear expression. The linear nature of the sum is further illuminated by considering functions or equations that involve only constants. If one function equals a constant and another equals a constant, their sum is also constant, preserving linearity.
In the context of linear differential equations, the principle that linear combinations of solutions are also solutions applies. This means that if we have two functions that are solutions to a linear differential equation, their sum (a linear combination) will also be a solution to the same linear differential equation. This indicates that linearity is preserved when combining linear items, whether they are expressions, functions, or equations.

One of the fastest recorded speeds of the elephant is 6.9 m/s. Approximately, what is this speed in kilometers per hour? [1 kilometer = 1,000 meters] [1 hour = 60 minutes = 3,600 seconds]
To answer this question, we know that 1km equals 1000m
and 1 hour is equal to 60 minutes. In the same way 1 minute equals 60 sec onds
So we have to change the units of elephant speed to km per hour.
For this we do the following procedure:
1) we multiply 6.9 m / s by the conversion factor from meters to kilometers (1 km / 1000m)
[tex]6.9 \frac{m}{s} *\frac{1 km}{1000 m}=0.0069\frac{km}{s} \\[/tex]
2) The result obtained is multiplied by the conversion factor from seconds to minutes (60s / 1min)
[tex]0.0069 \frac{km}{s} *\frac{60 s}{1 min}=0.414 \frac{km}{min}\\[/tex]
3) The result obtained is multiplied by the conversion factor from minutes to hours (60min / 1hr)
[tex]0.414\frac{km}{min}*\frac{60 min}{1 h}= 24.84\frac{km}{h} \\[/tex]
The answer is 24.84 km / h
You can skip step 2) multiplying 0.0069 km / s by the conversion factor from seconds to hours (3600 s / 1h)

x + 9 = 18 + -2x
x+9=18+-2x
divide 2x from both sides
which makes it 3x+9=18
subtract 9 from the 18
which is 3x=9
divide 3 from both sides
which gives you x=3
x+9=18+(-2x) add the 2x to the x and you should get 3x+9=18. Then you would subtract the 9 from the 18 and should get 3x=9. Then just divide the 9 by the 3 and get x=3 which is your answer. Hope this helps!
