Answer: 26/12

Step-by-step explanation:

26 goes on top and 12 on bottom because it says “spotted fish to plain fish” telling you which comes first and which one second

Answer:

13:6

Step-by-step explanation:

To simplify the ratio 26:12, we find the greatest common divisor of 26 and 12, and then we divide 26 and 12 by the greatest common divisor.

The greatest common divisor that you can use to simplify 26:12 is 2. Which means the answer to ratio 26:12 simplified is:

Answer:

d in (-oo:+oo)

(5/9)*d = 9/10 // - 9/10

(5/9)*d-(9/10) = 0

(5/9)*d-9/10 = 0

5/9*d-9/10 = 0 // + 9/10

5/9*d = 9/10 // : 5/9

d = 9/10/5/9

d = 81/50

d = 81/50

Answer:

Pedigrees of autosomal recessive traits will have equal frequencies of affected males and females, whereas pedigrees X-linked recessive traits will show that most of the affected individuals are male.

Step-by-step explanation:

If the trait is dominant, one of the parents must have the trait. Dominant traits will not skip a generation. If the trait is recessive, neither parent is required to have the trait since they can be heterozygous.A pedigree is a chart which shows the inheritance of a trait over several generations. From studying a pedigree, scientists can determine if a trait is sex-linked or autosoma If an individual has that trait, their symbol on the pedigree will be shaded in. If they have no widow's peak, their symbol will not be shaded in because having no widow's peak is recessive. Certain traits like colorblindness are located on the X or Y chromosome and are called sex-linked Several basic modes of inheritance exist for single-gene disorders: autosomal dominant, autosomal recessive, X-linked dominant, and X-linked recessive. However, not all genetic conditions will follow these patterns, and other rare forms of inheritance such as mitochondrial inheritance exist Autosomal recessive patterns manifest by skipping generations as the affected are usually children of unaffected carriers. It is also common to see affected individuals with unaffected offspring. ... The most common situation of an autosomal recessive disease occurs when the parents are each carrier or heterozygous (Dd)

Answer:

X-linked recessive.

Step-by-step explanation:

To start reading a pedigree:

Determine whether the trait is dominant or recessive. If the trait is dominant, one of the parents must have the trait. Dominant traits will not skip a generation. If the trait is recessive, neither parent is required to have the trait since they can be heterozygous.

Determine if the chart shows an autosomal or sex-linked (usually X-linked) trait. For example, in X-linked recessive traits, males are much more commonly affected than females. In autosomal traits, both males and females are equally likely to be affected (usually in equal proportions).

Answer:

d) 1/x^15

Step-by-step explanation:

first, you would multiply the exponents

(x^3)^-5

x^-15

second, in order for it to be simplified, you can not have a negative exponent, so you will move x^15 to the denominator.

Answer:

The relation in the fourth table (last table) represents the function.

Step-by-step explanation:

We know that a function is a relation where each input or x-value of the X set has a unique y-value or output of the Y set.

In other words, we can not have duplicated inputs as there should be only 1 output for each input.

If we carefully observe, we can check that the first three tables have duplicated inputs.

i.e. In tabel 1, x = 0 is repeated. In other words, x = 0 is duplicated.

i.e. In tabel 2, x = 7 is repeated. In other words, x = 7 is duplicated.

i.e. In tabel 3, x = 3 is repeated. In other words, x = 3 is duplicated.

Therefore, the first three tables DO NOT represent a function as we can not have duplicated inputs as there should be only 1 output for each input.

But, if we check the fourth table, it is clear that the fourth table does not have any duplicated input values.

i.e.

x = 14, 18, 1, and 17

Thus, in the fourth table, each input or x-value of the X set has a unique y-value or output of the Y set.

Hence, the relation in the fourth table (last table) represents the function.

710% expressed in fraction as 710/100 and expressed in decimal as 7.1.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, the fastest boat can reach speeds more than 710% as fast as the queen Mary 2.

Now, 710% as a decimal, we get

710/100 =7.1

Therefore, 710% expressed in fraction as 710/100 and expressed in decimal as 7.1.

Answer:

D.

Step-by-step explanation:

first, classic pythagoras with the smaller triangle.

3² + 4² = 25

sqrt 25 = 5

ok ok, now

5 can be turned into 15 by multiplying 3. do this with 4 and 3 to make the full triangle.

3 -> 9 (line AE)

4 -> 12 (line DE)

5 -> 15 (line AD)

The values of (a) and (b) are: [tex]a = 51[/tex] and [tex]b = -7[/tex]

The equation is given as:

[tex]4(9x + 11) + 5(3x + b) = ax + 9[/tex]

Expand the bracket

[tex]36x + 44 + 15x + 5b = ax + 9[/tex]

Collect like terms

[tex]36x + 15x+ 44 + 5b = ax + 9[/tex]

Evaluate like terms

[tex]51x+ 44 + 5b = ax + 9[/tex]

Compare both sides of the equation.

So, we have:

[tex]ax = 51x[/tex]

and

[tex]44 + 5b = 9[/tex]

In [tex]ax = 51x[/tex];

Divide both sides of the equations by x

[tex]a = 51[/tex]

In [tex]44 + 5b = 9[/tex],

Collect like terns

[tex]5b = 9 -44[/tex]

[tex]5b = -35[/tex]

Divide both sides of the equations by 5

[tex]b = -7[/tex]

Hence, the values of (a) and (b) are:

[tex]a = 51[/tex] and [tex]b = -7[/tex]

Step-by-step explanation:

so u have (2, 14) and (5, 20) those two are (x,y) ur gonna put it over each other by doing it like this y^2-y^1 and x^2-x^1 so like this over each other but its y first then x (2x^1, 14y^1) (5x^2, 20y^2) then subtract those and simplify ur final answer!

y=2x+10

find slope by doing y2-y1 over x2-x1

then choose a point to plug into y=mx+b (I chose 2,14)

after that solve for b using pemdas

the you get 10 as b

Answer: The earliest evidence of written mathematics dates back to the ancient Sumerians, who built the earliest civilization in Mesopotamia. They developed a complex system of metrology from 3000 BC.

Step-by-step explanation: Perhaps the most important reason to study math is because the study of mathematics builds problem-solving skills. All citizens need to know how to reason and analytically think through a problem. The habits of mind associated with learning mathematics trains our brains to seek solutions in a logical way.

Answer:

y=25-15x (i hope it is right)

Answer: All you possible answer are y=25-15x, y=-15x+25, y=5(-3x+5), and -5(3x-5). Keep in mind that these answers all mean the same thing and have that same value but they are in different forms.

Step-by-step explanation:

To isolate the y, subtract 15x from both sides of the equation (in order to keep the equation balanced). You should get 15x+y-15x=25-15x. Simplify and your equation will be y=25-15x. It could also be rearranged to be y=-15x+25. If you want to go a step further, you can factor out 5 from -1x and 25 to get y=5(-3x+5). Finally, if you wanted to go even further, you could factor out -5 to get y=-5(3x-5). So all you possible answer are y=25-15x, y=-15x+25, y=5(-3x+5), and -5(3x-5). I don't really know which form you need it in. Hope this helps!

Step-by-step explanation:

Opposite sides of a rectangle are congruent. Therefore the sides are 5x, 2x, 5x, and 2x. When you combine like terms, you get 14x. Therefore, the perimeter of the rectangle is 14x.

Answer: 14x
