Three sisters are saving for a special trip . The ratio of Nora​'s savings to Helga​'s savings is 8:3 and the ratio of Helga​'s savings to ​Maurice's savings is 3:4. Together all 3 have saved ​$60. How much has each ​saved?

Answers

Answer:

X = 10.588

Y = 28.2

Z = 21.176

Step-by-step explanation:

Consider Nova savings as X

Helga is Y

Maurice is Z

As per first ratio we conclude 8X=3Y

Second ratio we conclude 3Y = 4Z

We deduce 8X = 4Z

Last sentence => X+Y+Z=60 multiple it by 3

=> 3X + 3Y + 3Z= 180 but 8X = 4Y

=> 3X + 8X + 3Z =180 => 11X + 3Z=180 multiple the equation by 4/3

44/3 X + 4Z = 240 but 4Z = 8X

=> 44/3 X + 8 X = 240

=> 68/3 X = 240

=> 68X = 720

=> X =10.588

And Y=8/3 X =28.2

And Z=3/4 Y = 21.176

Each term is a sum of the two previous terms like the fibonacci sequence, but the sum of the two starting terms of the lucas sequence is followed by 2 then 1, rather than 0 then 1 for the fibannaci sequence.

These are integer sequences.

The sum of the two previous terms can be represented by:

fn = fn-1 + fn-2.

These numbers can be obtained by adding the previous corresponding term of the fibonacci sequence by the next corresponding term to get the corresponding number of the lucas sequence.

Ln = { 2 if n = 0

1 if n = 1

Ln-1 + Ln-2 if n > 1

________________

Fn+1 + Fn-1 = Ln

___________________

f(0) = -1

f(1) = 2, f(2) = 1, f(3) = 3, f(4) = 4, f(5) = 7, f(6) = 11

________________________________

f(12) = 199

________

f(12) = f(11) + f(10) = (f(10) + f(9)) + (f(9) + f(8)) = .....

given f(n) = f(n-1) + f(n-2)

____________________

f(12) = f(1) + f(2) = f(2) + f(3) = f(3) + f(4) =

f(4) + f(5) = f(5) + f(6) = f(6) + f(7) =

f(7) + f(8) = f(8) + f(9) = f(9) + f(10) =

f(10) + f(11) = f(12) →

f(12) = 2 + 1 = 1 + [3] = 3 + [4] = 4 + [7] =

7 + [11] = 11 + [18] = 18 + [29] = 29 + [47] =

47 + [76] = 76 + [123] = 199

Calculate the range and the mean of:
14, 8, 32, 8, 6, 4​

Answers

Answer:

Range: 28

Mean: 12

Step-by-step explanation:

First line the numbers from small to big: 4, 6, 8, 8, 14, 32

Range is biggest minus smallest number

Mean is just the average: all the numbers' sum divided by the number of numbers

Hope this helps! ;)

To get the mean you add up the numbers and divide it by how many numbers there are so:
14+8+32+8+6+4 = 72
72/6 = 12
Therefore the mean is 12

To get the range, you do the highest number minus the lowest number so:
32-4 = 28
Therefore the range is 28 as that is the difference between the highest and lowest number

Clarence made a diagram to compare codominance and incomplete dominance. Which label belongs in the area marked Y? Neither allele is dominant. An intermediate phenotype is expressed in offspring. One allele is dominant over the other. Both dominant alleles are fully expressed in offspring.

Answers

Answer:

The correct answer is both dominant alleles are fully expressed in offspring.      

In the incomplete dominance inheritance, one allele is not completely expressed over its paired allele and forms an intermediate trait, whereas in co-dominance, both the alleles express completely resulting into a new phenotype. For example AB blood group in humans.  

In the given question Y is the intersection of co-dominance set and incomplete dominance set. Thus, the area Y may have one dominant allele from co-dominance and one allele which is not completely dominant from incomplete dominance.

Therefore, the label to marked area Y may be - both dominant alleles are fully expressed in offspring.

What is a function?

Function is a type of relation, or rule, that maps one input to specific single output.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable. In mathematics and the physical sciences, functions are indispensable for formulating physical.

Thus, the table shows that the function is exponential rather than linear.

We are given the table through which we have to make a function.

I believe the answer is C.

Step-by-step explanation:

given we have peanuts to be $2 per pound, and cashews $5 per pound. If we use the equation p+c=25 then p would be (2×10=20), and c would be (5×1=5). then, to solve the problem we would do p+c=25 which p would be 20, and c would be 5, then add and it would equal 25.

Answer:

20,020 in. on the plans

Step-by-step explanation:

To get from 11 in. to 88 in. (from plans to real life), you multiply by 8.

Therefore, to get from 160,160 to ?? (from real-life to plans), you would divide by 8.

160,160 / 8 = 20,020

To check, you can multiply 20,020 by 8 to go from plans to real-life measurements; 20,020 • 8 = 160,160)

Bobby rode his skateboard 4 miles 30 rode her bicycle 10 miles in minutes. Who traveled at a greater average speed? Define an appropriate unit of speed and provide mathematical justification for your answer.

Answers

Answer:

Abelito had the greater average speed

Step-by-step explanation:

Given

Bobby:

[tex]Distance =4\ miles[/tex]

[tex]Time = 30\ minutes[/tex]

Abelito

[tex]Distance = 10\ miles[/tex]

[tex]Time = 48\ minutes[/tex]

Required:

Who had a greater average speed

Average speed (S) is calculated as:

[tex]S = \frac{Distance}{Time}[/tex]

We will make use of mph (miles per hour) as the unit of speed.

For Bobby:

[tex]S_B = \frac{4\ miles}{30\ minutes}[/tex]

Convert minute to hour

[tex]S_B = \frac{4\ miles}{0.5\ hr}[/tex]

[tex]S_B = 8mph[/tex]

For Abelito

[tex]S_A = \frac{10\ miles}{48\ minutes}[/tex]

Convert minute to hour

[tex]S_A = \frac{10\ miles}{0.8\ hr}[/tex]

[tex]S_A = 12.5mph[/tex]

By comparison: 12.5mph > 8mph

Hence: Abelito had the greater average speed
