If a:b= 1:2 then find the value of (3a+b) : (4a+ 2b)

Answers

Answer:

(3a + b) : (4a +2b) = 5 : 8

Step-by-step explanation:

For:

[tex]a : b = 1 : 2[/tex]

Express these ratios into fractions:

[tex] \frac{a}{b} = \frac{1}{2} [/tex]

Simplify:

[tex]2a = b - - - \{eqn \: (n) \}[/tex]

For:

[tex](3a + b) : (4a +2 b)[/tex]

Express into fractions:

[tex] = \frac{(3a + b)}{(4a + 2b)} \\ [/tex]

substitute for b as 2a from equation (n):

[tex] = \frac{(3a + 2a)}{(4a + 4a)} \\ \\ = \frac{5a}{8a} \\ \\ = \frac{5}{8} [/tex]

express into ratios:

[tex] = 5 : 8[/tex]

Ryan has 21 pencils. He wants to put the same number of pencils in each of 3 pencil holders. How many pencils will he put in each pencil holder

Answers

21 divided by 3 equals 7

7 pencils in each holder

:]

Ryan will put 7 pencils in each pencil holder.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. If an event can occur in "m" in different ways and if following it, a second event can occur in "n"  ways; then the two events in succession can occur in m × n  ways.

Given that Ryan has 21 pencils, wants to put the same number of pencils in each of the 3 pencil holders.

Pencil = 21

Pencil holder = 3

Therefore, we will do as 21 divided by 3

21/3 = 7

Hence, there are 7 pencils in each pencil holder.

Answer:

  -1/2048

Step-by-step explanation:

The Order of Operations tells you to evaluate each of the exponential expressions first. Then you do the division.

  = (1/32) / (-64)

  = -1/(32·64) = -1/2048

__

You can also rewrite the expression in terms of powers of 2.

  2^-5/-4^3 = -1/((2^5)(2^2)^3) = -1/(2^5×2^6) = -1/2^11

  = -1/2048

_____

The applicable rules of exponents are ...

  a^-b = 1/a^b

  (a^b)^c = a^(bc)

  (a^b)(a^c) = a^(b+c)

because from the graph x = 2pie

= cos pie = -1

The function whose graph is given by; cos (1/2 x )

What is graph?

A graph contains data of which input maps to which output.

Analysis of this leads to the relations which were used to make it.

For example, if the graph of a function is rising upwards after a certain value of x,  the function must be having increasingly output for inputs greater than that value of x.

If the function crosses x axis at some point, then for some polynomial functions, we have those as roots of the polynomial.

The function that we are given graphed has the point (0,1), this means whichever function f(x) it represents f(0) = 1.

Now, only the cosine function has the property that cos(π) = -1, thus

y = cos (x/2)

because from the graph x = 2π

The function whose graph is given by; cos (1/2 x )

What is Simplification?

Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.

Given, the values of a and b are 9/11 and 7/10 respectively

thus,

ab = 9/11 * 7/10

simplifying it

ab = 63/110

Therefore, the value of ab is 63/110 when a = 9/11 and b = 7/10
