Select each situation that can represent a proportional relationship.
A) The total amount a babysitter makes who earns $10 an hour for babysitting r hours.
B) The total amount of snow that falls in d days when there's already 5 inches of snow on the ground.
C) The total amount Andrew saves when he saves $24 a week for w weeks.
D) The length in x months of a baby that grows 2 inches per month and was born 7 inches long.
Using the concept of proportionality, it is found that these following situations represent proportionality:
A) The total amount a babysitter makes who earns $10 an hour for babysitting r hours.
C) The total amount Andrew saves when he saves $24 a week for w weeks.
In a proportional relationship, the output y is given by the input x multiplied by a constant k, that is:
[tex]y = kx[/tex].
Thus, when x = 0, y = 0.In this problem:
In options A and C, when the input is 0, the output is also 0, thus they are proportional.In option B, when the input is 0 days, the output is 5 inches of snow, thus it is not proportional.In option D, when the input is of 0 months, the height is of 7 inches, thus also not proportional.A similar problem is given at https://brainly.com/question/22846068

1) Let x = 0.5
2) 10x = 5.5
3) 10x = 5.5
-x = 0.5
________
9x=5

Convert 1AA from hexadecimal to decimal.
1AA = 426
What an odd class...
Answer:
426 in decimal.
Step-by-step explanation:
Step 1) Count the digits in 1AA, which in this case is 3 digits, and convert each digit to Hex.
Step 2) Starting from the last number in Step 1, multiply the first number with 1, the second number with 16, and the third number with 256.
Step 3) Add up all the numbers you got in Step 2 to get the answer.
Following the instructions above, your math should look like this:
10 x 1 = 10
10 x 16 = 160
1 x 256 = 256
10 + 160 + 256 = 426
Thus, we got the following answer:
1AA = 426

Calculate 1 + 3 + 5 +...+ (2n - 1) for several natural numbers n.
Answer:
The solutions for 1 + 3 + 5 +...+ (2n - 1), for the first 10 natural numbers are given in the explanation section below.
Step-by-step explanation:
To calculate 1 + 3 + 5 +...+ (2n - 1) for several natural numbers n, we will use several natural numbers to represent n.
For n= 1,
2n - 1 = 2(1) - 1 = 2 - 1 = 1
Hence, 1 = 1
For n = 2,
2n - 1 = 2(2) - 1 = 4 - 1 = 3
Hence, 1 + 3 = 4
For n = 3,
2n - 1 = 2(3) - 1 = 6 - 1 = 5
Hence, 1 + 3 + 5 = 9
For n = 4,
2n - 1 = 2(4) - 1 = 8 - 1 = 7
Hence, 1 + 3 + 5 + 7 = 16
For n = 5,
2n - 1 = 2(5) - 1 = 10 - 1 = 9
Hence, 1 + 3 + 5 + 7 + 9 = 25
For n = 6,
2n - 1 = 2(6) - 1 = 12 - 1 = 11
Hence, 1 + 3 + 5 + 7 + 9 + 11 = 36
For n = 7,
2n - 1 = 2(7) - 1 = 14 - 1 = 13
Hence, 1 + 3 + 5 + 7 + 9 + 11 + 13 = 49
For n = 8,
2n - 1 = 2(8) - 1 = 16 - 1 = 15
Hence, 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 = 64
For n = 9,
2n - 1 = 2(9) - 1 = 18 - 1 = 17
Hence, 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 = 81
For n = 10,
2n - 1 = 2(10) - 1 = 20 - 1 = 19
Hence, 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 = 100

Which set of transformations would prove ΔLMN ~ ΔPQR?
Answer:
B. Dilate ΔPQR by the scale factor of 2 from point Q, and translate ΔP′Q′R′ by the rule (x + 1, y + 0).
Step-by-step explanation:
Dilations make the most sense for the shapes shown, and it can't be A because if you were to do y - 1 then it would be further away and would no longer be equivalent.
Answer:
would actually be answer D. Translate ΔPQR by the rule (x + 1, y − 1), and dilate ΔP′Q′R′ by a scale factor of 2 from point R.

Step-by-step explanation:
need help to determine if it's a undefined slope or it is a slope of line and what's the answer please and thank you
Answer:
It is slope of a line which is 4
Step-by-step explanation:
We are given that the given points are generated by a linear function. A linear function is ta straight line that can be represented by:
[tex]y = mx+b[/tex]
Here m is the slope
The slope of a line is given by the formula:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
In order to find the slope from the table we take any two pairs of inputs and outputs i.e. x and y
So here we take
(x1,y1) = (-6,-16)
(x2,y2) = (-5,-12)
Putting the values in the formula
[tex]m = \frac{-12-(-16)}{-5-(-6)}\\m = \frac{-12+16}{-5+6}\\m = \frac{4}{1}\\m = 4[/tex]
Hence,
It is slope of a line which is 4

Find the volume of the tetrahedron with the given vertices. (4, 0, 0), (0, 4, 0), (0, 0, 1), (4, 4, 1)
Answer:
[tex]\mathbf{V = \dfrac{16}{3}}[/tex]
Step-by-step explanation:
From the information given:
A = (4,0,0) B = (0,4,0) C = (0,0,1) D = (4,4,1)
[tex]\overline{ AB}[/tex] = (0,4,0) - (4,0,0) = (-4, 4, 0)
[tex]\overline{ BC} =[/tex] (0,0,1) - (0,4,0) = (0, -4, 1)
[tex]\overline{ CD}[/tex] = (4,4,1) - (0,0,1) = (4, 4, 0)
The Volume of the tetrahedron [tex]V = \dfrac{1}{6} \bigg| AB \times BC \times CD \bigg|[/tex]
The Volume of the tetrahedron [tex]V = \dfrac{1}{6} \left\begin{vmatrix}-4,&4&0\\0,&-4&1\\4&4&0\end{vmatrix}\right[/tex]
[tex]V = \dfrac{1}{6}\bigg [ -4(-4 *0 - 1*4) -4(0*0-1*4) +0(0*4--4*4) \bigg ][/tex]
[tex]V = \dfrac{1}{6}\bigg [ -4(0 - 4) -4(0-4) +0(0+16) \bigg ][/tex]
[tex]V = \dfrac{1}{6}\bigg [ 16 + 16 +0 \bigg ][/tex]
[tex]V = \dfrac{1}{6}\bigg [ 32 \bigg ][/tex]
[tex]\mathbf{V = \dfrac{16}{3}}[/tex]
