Answer:
Step-by-step explanation:
From the question, Tom paid $16 for 6 audio cassettes and we are told to find the proportion to get the amount of money (m) he would pay for 9 audio cassettes. To get this, we have to know the amount of the cost of 1 audio cassette. Since Tom paid $16 for 6 audio cassettes, 1 audio cassette will cost:
= $16/6
= $2.67
1 audio cassette will cost $2.67
The amount of money spent will depend on the number of audio cassettes. Therefore,
m = $2.67 × n
m = $2.67n
where n = number of audio cassette
The amount of money he'll pay for 9 cassette will be:
m = $2.67n
m = $2.67 × 9
m = $24.03

Find the minimum value of C=x+3y
Answer:
c
Step-by-step explanation:
2x + 3y > 6 (1)
3x – 2y = 9 (2)
x + 5y = 20 (3)
From (1) and (2), we have:
(2x + 3y) - (3x - 2y) > 6 - 9
5y - x > -3 (4)
From (3) and (4), we have:
(x + 5y) - (5y - x) > 20 - (-3)
2x > 23
x > 12,5 (5)
From (3) and (5), we have:
x + 5y = 20 ⇔ 12,5 + 5y > 20
5y > 7,5
y > 1,5
So: C = 4x + 3y > 12,5 × 4 + 1,5 × 3 = 50 + 4,5 = 54,5
Conclusion: C > 54,5

Triangle A B C is shown. Angle B C A is a right angle. The length of hypotenuse A B is 26, the length of A C is 10, and the length of B C is 24. Given right triangle ABC, what is the value of tan(A)? Five-thirteenths Twelve-thirteenths Twelve-fifths Thirteen-twelfths
Answer:
The right option is twelve-fifthsStep-by-step explanation:
Given a right angle triangle ABC as shown in the diagram. If ∠BCA = 90°, the hypotenuse AB = 26, AC = 10 and BC = 24.
Using the SOH, CAH, TOA trigonometry identity, SInce we are to find tanA, we will use TOA. According to TOA;
Tan (A) = opp/adj
Taken BC as opposite side since it is facing angle A directly and AC as the adjacent;
tan(A) = BC/AC
tan(A) = 24/10
tan(A) = 12/5
The right option is therefore twelve-fifths

Titik adalah bentuk yang paling dasar dalam geometri. Titik ditulis dengan tanda titik dan diberi nama dengan huruf besar. Sebuah titik hanya untuk menunjukkan posisi dan memiliki ukuran nol (panjang nol, lebar nol, dan tinggi nol).
Garis adalah kumpulan titik-titik yang memanjang secara tak berhingga ke dua arah. Sebuah garis memiliki panjang tidak terbatas.
Ruas garis adalah potongan sebuah garis. Sebuah ruas garis memiliki dua titik ujung dan diberi nama menurut kedua titik ujungnya.
Sinar garis merupakan bagian dari sebuah garis, namun hanya memiliki satu titik ujung. Sebuah sinar garis diberi nama dengan huruf titik ujungnya dan titik lain pada sinar garis tersebut.
Sudut adalah dua sinar yang memiliki titik ujung yang sama.
Titik ujung tersebut dinamakan titik sudut dan sinar-sinar garisnya dinamakan sisi-sisi sudut.
Bidang adalah kumpulan titik yang jumlahnya tak terhingga yang membentuk permukaan rata yang melebar ke segala arah sampai tak terhingga. Sebuah bidang memiliki panjang tak terbatas, lebar tak terbatas, dan tinggi nol. Sebuah bidang biasanya digambarkan dengan gambar segi empat dan diberi nama dengan satu huruf besar.
Rusuk adalah suatu garis yang merupakan pertemuan dari dua sisi bidang.
Dua bidang berpotongan bila terdapat garis persekutuan atau garis potong antara kedua bidang tersebut.
Dua bidang sejajar bila antara kedua bidang tersebut tidak memiliki garis persekutuan.
Dua bidang berhimpit bila setiap titik terletak pada kedua bidang tersebut.
Mari kita lihat soal tersebut.
Jika dua bidang saling berpotongan dan tidak berhimpitan, maka perpotongannya berbentuk garis.
Jadi, jawabannya adalah B.

It is pretty much the same thing as division, but in subtraction. Since, Dividing and Subtraction are a like, repeated subtraction is a great example to use for this example
Hope this helps. :)
Answer:
kk so like, division is just repeated subtraction. like idk say you have 36 and you divide it by 9 so I think you just keep subtracting 9 until you reach 0? so you end up subtracting 9 four times which happens to be the quotient for 36/9. yeah. it's almost like how multiplication is just repeated addition.
tom gets a bonus of 30% of £96
sally gets a bonus of £31.40
work out the difference between the bonus that tom gets and the bonus that sally gets
Answer:
The difference between the bonus is £2.6
Step-by-step explanation:
First, you have to calculate the amount that Tom get for his bonus. So you have to multiply 30% to £96 :
[tex] \frac{30}{100} \times 96 = 28.8[/tex]
Next, you have to subtract Tom's amount from Sally's amount because Sally has the higher amount of bonus than Tom :
[tex]31.4 - 28.8 = 2.6[/tex]
Which point is not in the solution set of the equation 3y + 2 = x2 − 5x + 17?
A) (-2,10) or
D) (5,5)
B and C where wrong.
Answer:
A (-2, 10)
Step-by-step explanation:
If you plug in the point into x and y you should get "false" on a calculator, or the answer won't make sense, meaning that it's not a part of the set
(-2,10) is not the solution set of the given equation [tex]3y+2 =x^{2} -5x+17[/tex].
What is solution to the equation?The solution, or root, of an equation is any value or set of values that can be substituted into the equation to make it a true statement.
According to the given question
We have an equation
[tex]3y + 2 =x^{2} -5x+17[/tex]
The above equation can be written as
[tex]x^{2} -5x +17-3y-2=0...(i)[/tex]
For finding the point which is not the solution set of the equation, first we will substitute the given points in the above equation and check whether it making the equation true or not.
For point (-2, 10)
Substitute, x = -2 and y = 10 in the equation (i)
[tex](-2)^{2} -5(-2) + 17 - 3(10) -2\\=4+10+17-30-2\\= -1\neq 0[/tex]
Hence, (-2, 10) is not the solution of the given equation.
For point (5, 5)
Substitute, x = 5, and y = 5 in equation (i)
[tex](5)^{2} -5(5)+17-3(5)-2\\=25-25+17-15-2\\=0[/tex]
Hence, (5, 5) is the solution of the given equation.

Submit
INTL
Answer:
The domain is {0.5, 1, 1.5, 2}
The range is {1.9, 3.8, 5.7, 7.6}
Step-by-step explanation:
The cost, y is in dollars, and x in pounds of almonds is shown in the table.
x (pounds) y ($)
0.5 1.9
1 3.80
1.5 5.70
2 7.60
The grocery store sells almond at $3.80 per pound, the relation between y and x is given by the function:
y = 3.8x
The x values are the independent variables and they serve as the input of the function while the y values are the dependent variables (dependent on x) and the serve as the output of the function.
The domain consist of input values which is the x values. The domain is {0.5, 1, 1.5, 2}
The range consists of all output values i.e the y values. The range is {1.9, 3.8, 5.7, 7.6}
Any number of pounds of almonds can be purchased, including partial amounts, so the relation described in the table is continuous.
Because x can be any positive number of pounds, the domain of the relation is x ≥ 0, or x-values greater than or equal to 0.
Because y can be any positive dollar amount, the range of the relation is y ≥ 0, or y-values greater than or equal to 0.

A certain pet store sells 6 times as many fish as kittens. It sells twice as many kittens as lizards. If the pet store sells 15 lizards a week, how many fish, kittens, and lizards does the pet store sell every week?
It sells twice as many kitten as lizards:
Kittens sold = 15 x 2 = 30 total kittens.
It sells 6 times the amount of fish:
Fish sold = 6 x 30 = 180 total fish.
Lizards = 15
Kittens = 30
Fish = 180
Answer:
They sell 225 pets each week.
Step-by-step explanation:
Let f be fish, k be kittens, and l be lizards.
[tex]f[/tex]÷6=[tex]k[/tex]
[tex]k[/tex]÷2=[tex]l[/tex]
If [tex]l=15[/tex], then:

How do I do this? I can't remember how and Algebra 2 has always been a struggle for me
Answer:
Step-by-step explanation:
This is a piecewise function. If we are finding the average rate of change over the interval 4 and 12 inclusive, that means that we are finding the slope of the whole function (both pieces) from 4 to 12 (domain values are from 4 to 12. That means x values). This is not a straight line, so the average value is merely a rough estimate of the slope between x values 4 and 12.
When x ≤ 4, we have to use the first piece of the function, 3x - 7 because the restriction on the domain is that x has to be less than 6 and 4 is less than 6. Evaluating at the domain of 4 in the first piece will give us an (x, y) coordinate to help find the slope.
f(4) = 3(4) - 7 and
f(4) = 12 - 7 so
f(4) = 5 and the coordinate is (4, 5).
When x ≤ 12 we have to use the second piece of the function, .75x + 10 because the domain restriction is that x has to be greater than or equal to 6 and 12 is greater than 6. Evaluating at a domain of 6 will give us the other coordinate we need to find the slope.
f(12) = .75(12) + 10 and
f(12) = 9 + 10 so
f(12) = 19 and the coordinate is (12, 19). Now for the slope (aka average rate of change). Using the slope formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{19-5}{12-4}=\frac{14}{8}=\frac{7}{4}[/tex]
There you go! Just remember the domain thing and you should be fine.
