The lengths of the sides of a triangle are in the extended ratio 8 : 9 : 10. The perimeter of the triangle is 81 cm. What are the lengths of the sides?
The lengths of the sides are 24cm, 27cm and 30cm.
Step-by-step explanation:
The ratio of lengths is 8:9:10
Perimeter = 81 cm
Let x be the length of side.
Therefore,
The length of sides is 8x, 9x and 10x.
Perimeter is the sum of 3 sides, therefore,
[tex]8x+9x+10x=81\\27x=81[/tex]
Dividing both sides by 27;
[tex]\frac{27x}{27}=\frac{81}{27}\\x=3[/tex]
Therefore, the lengths of sides are [tex]8(3), 9(3)\ and\ 10(3)[/tex]
The lengths of the sides are 24cm, 27cm and 30cm.

The lengths of the sides of the triangle are 24 cm, 27 cm, and 30 cm.
Explanation:To find the lengths of the sides of the triangle, we can use the fact that the sum of the lengths of the sides of a triangle is equal to the perimeter. Let's assume the common ratio between the sides is 'x'. So, the lengths of the sides can be written as 8x, 9x, and 10x. According to the problem, the perimeter of the triangle is 81 cm.
Therefore, 8x + 9x + 10x = 81.
Combining like terms, we get 27x = 81.
Dividing both sides by 27, we find that x = 3.
Substituting this value back into the lengths of the sides, we find that the lengths are 8x = 8(3) = 24 cm, 9x = 9(3) = 27 cm, and 10x = 10(3) = 30 cm.

The ratio of incomes of two persons is 9:7. The difference in their weekly incomes is $200. What are their weekly incomes?
What’s the answer
Answer:
The weekly savings of first person = $900
The weekly savings of second person = $700.
Step-by-step explanation:
Let us assume the income of first person = $ m
Now, as the difference in the income is $200.
⇒ And the income of first person - income of first person = $200
⇒ Income of second person = m - $200
So, according to the question:
Ratio of Income of First person : Second Person's Income = 9: 7
or, m : ( m - 200) = 9: 7
[tex]\implies \frac{m}{m - 200 } = \frac{9}{7}[/tex]
[tex]7 \times m = (m - 200) \times 9\\\implies 7 m = 9m - 1800\\\implies 7m - 9m = -1800\\\implies -2m = -1800\\m = \frac{1800}{2} = 900[/tex]
or,m = $900
Hence, the weekly savings of first person = $900
and the weekly savings of second person = m - 200 = $900 - 200 = $700.
Final answer:
To find the weekly incomes of two persons with a ratio of 9:7 and a difference of $200, represent their incomes as 9x and 7x. Solving for x, we get $100, so their incomes are $900 and $700 respectively.
Explanation:
The question asks us to solve for the weekly incomes of two persons given that the ratio of their incomes is 9:7 and the difference between their incomes is $200.
Let's represent the incomes of the two persons as 9x and 7x respectively, where x is a common multiplier. According to the information provided,
9x - 7x = $200
Solving for x:
(9x - 7x) = 2x
2x = $200
x = $200 / 2
x = $100
Now calculating each person's income:
Person A: 9x = 9 * $100 = $900
Person B: 7x = 7 * $100 = $700
Therefore, the weekly incomes of the two persons are $900 and $700 respectively.

Write an exponential function (in terms of x) to model the following situation.
A population of 110,000 grows 5% per year for 16 years.
How much will the popluation be after 16 years?
Answer:
The population will be 240,116
Step-by-step explanation:
Exponential growth can be represented by the expression:
[tex]P(t) = P_i\,(1+r)^t[/tex]
where:
[tex]P(t)[/tex] is the population at time (t)
[tex]P_i[/tex] is the initial value of the population
"r" is the annual rate of growth (written in decimal form)
and "t" is the time in years.
Therefore in this situation, P(16) is what we want to find [the population after 16 years]
the initial population [tex]P_i[/tex] is 110,000
the rate of growth is 0.05 [decimal form of 5%]
and t is 16 years.
Replacing all these in the given functional form gives:
[tex]P(t) = P_i\,(1+r)^t\\P(16)=110000\,(1+0.05)^16\\P(16)=240116[/tex]
An exponential function to model a population of 110,000 that grows at 5% per year for 16 years is P(t) = 110,000 ∙ (1.05)^t. After 16 years, using this exponential function, the population would be approximately 242,884.
Explanation:To model the population growth using an exponential function, we can use the formula P(t) = P0 ∙ (1 + r)t, where P(t) is the population after t years, P0 is the initial population, r is the growth rate, and t is the time in years. In this case, the initial population P0 is 110,000, the growth rate r is 5% (or 0.05), and the time t is 16 years.
The exponential growth function would be:
P(16) = 110,000 ∙ (1 + 0.05)16
To find the projected population after 16 years, we'll calculate:
P(16) = 110,000 ∙ (1.05)16
P(16) = 110,000 ∙ 2.20804
P(16) = 242,884.4
After rounding, the population would be approximately 242,884 after 16 years.
Carter is a songwriter who collects royalties on his songs whenever they are played in a commercial or a movie. Carter will earn $50 every time one of his songs is played in a commercial and he will earn $130 every time one of his songs is played in a movie. Carter earned a total of $1000 in royalties on 12 commercials and movies. Determine the number of commercials and the number of movies on which Carter's songs were played.
Carter's song played on 7 commercials and 5 movies.
Step-by-step explanation:
Earning per commercial = $50
Earning per movie = $130
Total earned = $1000
Total commercial and movies = 12
Let,
x be the number of commercials
y be the number of movies
According to given statement;
x+y=12 Eqn 1
50x+130y=1000 Eqn 2
From Eqn 1
x=12-y Eqn 3
Putting value of x from Eqn 3 in Eqn 2
[tex]50(12-y)+130y=1000\\600-50y+130y=1000\\80y=1000-600\\80y=400[/tex]
Dividing both sides by 80
[tex]\frac{80y}{80}=\frac{400}{80}\\y=5[/tex]
Putting y=5 in Eqn 1
[tex]x+5=12\\x=12-5\\x=7[/tex]
Carter's song played on 7 commercials and 5 movies.

Carter had his songs played in 7 commercials and 5 movies to earn $1000 in royalties. This was determined by solving a system of linear equations.
Carter is dealing with a system of linear equations situation where he collects different amounts of royalties based on whether his music is played in commercials or movies. We can represent the number of commercials as c and the number of movies as m. Since he earns $50 per commercial, we can write the first equation as 50c, and since he earns $130 per movie, we can write the second equation as 130m. Carter earned a total of $1000 from 12 commercials and movies, which gives us two equations:
50c + 130m = 1000
c + m = 12
By solving this system of equations, we can determine the number of commercials and movies. Multiplying the second equation by 50 gives us 50c + 50m = 600, which we can subtract from the first equation to eliminate c and solve for m. Doing so, we get:
50c + 130m = 1000
-(50c + 50m = 600)
After subtracting, we are left with 80m = 400, from which we can solve for m to find that m = 5. Using the second original equation, we can now find out that c = 7.
So, Carter had his songs played in 7 commercials and 5 movies to earn a total of $1000 in royalties.

Which of these sets could represent the side lengths of a right triangle?
Group of answer choices
{4, 8, 12}
{6, 8, 10}
{6, 8, 15}
{5, 7, 13}
Answer:
{6, 8, 10} is a set which represents the side length of a right triangle.
Step-by-step explanation:
In a right triangle:
[tex](Base)^{2} + (Perpendicular)^{2} = (Hypotenuse)^{2}[/tex]
Now, in the given triplets:
(a) {4, 8, 12}
Here, [tex](4)^{2} + (8)^{2} = 16 + 64 = 80\\\implies H = \sqrt{80} = 8.94[/tex]
So, third side of the triangle 8.94 ≠ 12
Hence, {4, 8, 12} is NOT a triplet.
(b) {6, 8, 10}
Here, [tex](6)^{2} + (8)^{2} = 36 + 64 = 100\\\implies H = \sqrt{100} = 10[/tex]
So, third side of the triangle 10
Hence, {6, 8, 10} is a triplet.
(c) {6, 8, 15}
Here, [tex](6)^{2} + (8)^{2} = 36 + 64 = 100\\\implies H = \sqrt{100} = 10[/tex]
So, third side of the triangle 10 ≠ 15
Hence, {6, 8, 15} is NOT a triplet.
(d) {5, 7, 13}
Here, [tex](5)^{2} + (7)^{2} = 25 + 49 = 74\\\implies H = \sqrt{74} = 8.60[/tex]
So, third side of the triangle 8.60 ≠ 13
Hence, {5, 7, 13} is NOT a triplet.

Step-by-step explanation:
The value of a variable change from 12 units to 16 units in a month.
We have to calculate the percentage increase for that month.
Therefore, the increase of value from 12 to 16 means by (16 - 12) = 4 units

Triangle ABC has side lengths: V6, V2, and 2/2 units.
The measures of the angles of the triangle are
If the base of the triangle has a length of 16 then the measure of the base angle is
Answer:
90°, 60°, and 30°
60°.
Step-by-step explanation:
The triangle ABC has side lengths √6, √2, and 2√2 units.
It is clear that the triangle ABC is right triangle because (2√2)² = (√6)² + (√2)² that means the side lengths satisfy the Pythagoras Theorem.
Now, if the angle between hypotenuse (2√2 units) and base (√2 units) is [tex]\theta[/tex], then
[tex]\cos \theta = \frac{\sqrt{2} }{2\sqrt{2} } = \frac{1}{2}[/tex]
Hence, [tex]\theta[/tex] = 60°
Therefore, the three angles of the triangle are 90°, 60°, and 30°.
Now, if the base of the triangle is 16 units, then other two side lengths will also change proportionally to remain the triangle a right triangle.
And in that case the base angle will remain 60°. (Answer)
what is the median,lower quartile,maximum,upper quartile,and the minimum of 34, 37, 39, 32, 48, 45, 53, 62, 58, 61, 60, 41
Answer:
Median = 46.5
Minimum = 32
Maximum = 62
Lower quartile = 38
Upper quartile = 59
Step-by-step explanation:
Before we can proceed to solving any of these, it is best you arrange your data first from least to greatest
32 34 37 39 41 45 48 53 58 60 61 62
First we have the median. The Median is the middle value. In this case we an even number of data, which is 12 data points. The middle value of the data would be found in between the 6th and 7th data point:
45 and 48
To get the middle value, you need to solve for the value that is in the middle of 45 and 48 by getting the sum of both numbers and dividing it by two.
45 + 48 = 93
93 ÷ 2 = 46.5
The minimum and maximum value is merely the least and greatest number.
Here we have:
Minimum = 32
Maximum = 62
To get the lower and upper quartiles, just remember that quartiles divide the data into 4 equal parts. All you need to do is find the value that is in between each quarters of the data:
Q1 (Lower) Q2(Median) Q3(Upper)
32 34 37 | 39 41 45 | 48 53 58 | 60 61 62
Like the median, we will find the value that comes in between each quarter.
Q1
37 + 39 = 76
76 ÷ 2 = 38
Lower quartile = 38
Q3:
58 + 60 = 118
118 ÷ 2 = 59
Upper quartile = 59

√25 · 5 + √25
√125 + 5 or 16.18
Calculate the unknown angles
Answer:
see explanation
Step-by-step explanation:
Since the 2 lines are parallel, then
d = 55° ( corresponding angles are congruent )
e = 55° (vertical to d and congruent )
e and f are same side interior angles and are supplementary, thus
e + f = 180°, that is
55° + f = 180° ( subtract 55° from both sides )
f = 125°
c = 125° ( alternate to f and congruent )
Hence
c = 125°, d = 55°, e = 55°, f = 125°

[tex]x,\ y-numbers\\\\\text{The system of equations:}\\\\\underline{+\left\{\begin{array}{ccc}x+y=126\\x-y=42\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad2x=168\qquad\text{divide both sides by 2}\\.\qquad x=84\\\\\\\text{Put the value of}\ x\ \text{to the first equation:}\\\\84+y=126\qquad\text{subtract 84 from both sides}\\y=42[/tex]
Final answer:
The two numbers that have a sum of 126 and a difference of 42 are 84 and 42.
Explanation:
To find the two numbers whose sum is 126 and whose difference is 42, we can set up a system of equations:
x + y = 126 (Sum of the numbers)
x - y = 42 (Difference of the numbers)
By adding these two equations, we can eliminate y and solve for x:
x + y + x - y = 126 + 42
2x = 168
x = 84
Now that we have the value of x, we can find y by substituting x back into either of the equations. For example:
84 + y = 126
y = 126 - 84
y = 42
Therefore, the two numbers are 84 and 42.
