Final answer:

The missing fraction in the equation 9/10 + ?/? = 99/100 is 9/100 because 9/10 is equivalent to 90/100 and 99/100 - 90/100 equals 9/100.

Explanation:

To find the missing fraction in the equation 9/10 + ?/? = 99/100, we need to find a common denominator and then solve for the numerator of the missing fraction. The common denominator for 10 and 100 is 100, so we must convert 9/10 into an equivalent fraction with a denominator of 100, which is 90/100. Now, to find the missing numerator, we subtract 90/100 from 99/100 which gives us 9/100. Therefore, the missing fraction is 9/100.

Answer: y = -2x + 10

Step-by-step explanation:

Two lines are said to be perpendicular if the product of their slope = -1, that is , if [tex]m_{1}[/tex] is the slope of the first line and [tex]m_{2}[/tex] is the slope of the second line , if the two lines are perpendicular , then [tex]m_{1}[/tex][tex]m_{2}[/tex] = -1

The equation of the line given :

y = 1/2x - 1

comparing with the equation of line in slope intercept form

y = mx + c , where m is the slope and c is the y - intercept , it implies that

[tex]m_{1}[/tex] = 1/2

Therefore :

[tex]m_{2}[/tex] = -2

To find the equation of the line with slope -2  and passes through the point ( 3 , 4 ) we will use the formula

[tex]y-y_{1}[/tex] = m ([tex]x-x_{1}[/tex] )

y - 4 = -2 ( x - 3 )

y - 4 = -2x + 6

y = -2x + 6 + 4

Answer:

Thymine 23

Guanine 27

Step-by-step explanation:

A DNA molecule consists of two long chains of DNA connected to each other through the bonds nitrogenous bases make one with another. However, this bonding is strictly regulated through Chargaff's rule. It basically says that adenine from one DNA chain can only bond with thymine from another chain and vice versa. Additionally, cytosine from one chain only bonds with guanine from another and vice versa:

[A] = [T]

[G] = [C]

That means that there should be an equal number of corresponding bases.

If there were 23% of adenine, there will also be 23% of thymine.

Similarly, if there were 27% of cytosine, there will also be 27% of guanine.

Also note that the sum of non-bonding bases is always 50%, in this case, adenine + cytosine was 23% + 27% = 50%.

The Answer is: Thymine 23

Then Guanine 27

There are approximately 745 pages in main story

Solution:

Let "x" be the number of pages in main story

Let "y" be the number of pages in prologue

Given that there are 750 pages in all

Therefore,

number of pages in main story + number of pages in prologue = 750

x + y = 750 ---------- eqn 1

The main story has 150 times as many pages as the prologue

Therefore, a equation is framed as:

number of pages in main story = 150(number of pages in prologue)

x = 150y ----------- eqn 2

Let us solve eqn 1 and eqn 2

Substitute eqn 2 in eqn 1

150y + y = 750

151y = 750

y = 4.967

Substitute y = 4.967 in eqn 2

x = 150(4.967)

x = 745.05

Thus there are approximately 745 pages in main story

Answer:

[tex]\frac{12q^{\frac{7}{3}}}{p^{3}}[/tex]

Step-by-step explanation:

Here are some rules you need to simplify this expression:

Distribute exponents: When you raise an exponent to another exponent, you multiply the exponents together. This includes exponents that are fractions. [tex](a^{x})^{n} = a^{xn}[/tex]

Negative exponent rule: When an exponent is negative, you can make it positive by making the base a fraction. When the number is apart of a bigger fraction, you can move it to the other side (top/bottom). [tex]a^{-x} = \frac{1}{a^{x}}[/tex], and to help with this question: [tex]\frac{a^{-x}b}{1} = \frac{b}{a^{x}}[/tex].

Multiplying exponents with same base: When exponential numbers have the same base, you can combine them by adding their exponents together. [tex](a^{x})(a^{y}) = a^{x+y}[/tex]

Dividing exponents with same base: When exponential numbers have the same base, you can combine them by subtracting the exponents. [tex]\frac{a^{x}}{a^{y}} = a^{x-y}[/tex]

Fractional exponents as a radical: When a number has an exponent that is a fraction, the numerator can remain the exponent, and the denominator becomes the index (example, index here ∛ is 3). [tex]a^{\frac{m}{n}} = \sqrt[n]{a^{m}} = (\sqrt[n]{a})^{m}[/tex]

[tex]\frac{(8p^{-6} q^{3})^{2/3}}{(27p^{3}q)^{-1/3}}[/tex]        Distribute exponent

[tex]=\frac{8^{(2/3)}p^{(-6*2/3)}q^{(3*2/3)}}{27^{(-1/3)}p^{(3*-1/3)}q^{(-1/3)}}[/tex]        Simplify each exponent by multiplying

[tex]=\frac{8^{(2/3)}p^{(-4)}q^{(2)}}{27^{(-1/3)}p^{(-1)}q^{(-1/3)}}[/tex]        Negative exponent rule

[tex]=\frac{8^{(2/3)}q^{(2)}27^{(1/3)}p^{(1)}q^{(1/3)}}{p^{(4)}}[/tex]        Combine the like terms in the numerator with the base "q"

[tex]=\frac{8^{(2/3)}27^{(1/3)}p^{(1)}q^{(2)}q^{(1/3)}}{p^{(4)}}[/tex]        Rearranged for you to see the like terms

[tex]=\frac{8^{(2/3)}27^{(1/3)}p^{(1)}q^{(2)+(1/3)}}{p^{(4)}}[/tex]        Multiplying exponents with same base

[tex]=\frac{8^{(2/3)}27^{(1/3)}p^{(1)}q^{(7/3)}}{p^{(4)}}[/tex]        2 + 1/3 = 7/3

[tex]=\frac{\sqrt[3]{8^{2}}\sqrt[3]{27}p\sqrt[3]{q^{7}}}{p^{4}}[/tex]        Fractional exponents as radical form

[tex]=\frac{(\sqrt[3]{64})(3)(p)(q^{\frac{7}{3}})}{p^{4}}[/tex]        Simplified cubes. Wrote brackets to lessen confusion. Notice the radical of a variable can't be simplified.

[tex]=\frac{(4)(3)(p)(q^{\frac{7}{3}})}{p^{4}}[/tex]        Multiply 4 and 3

Answer:

The interest rate should be 11.6%.

Step-by-step explanation:

Let us assume that at r% rate of interest compounded annually is required to triple an investment of $P in 10 years.

So, using the formula of compound interest, we can write

[tex]3P = P(1 + \frac{r}{100})^{10}[/tex]

⇒ [tex]3 = (1 + \frac{r}{100})^{10}[/tex]

⇒ [tex](1 + \frac{r}{100}) = 1.116[/tex]

⇒ [tex]\frac{r}{100} = 0.116[/tex]

⇒ r = 11.6 %

Therefore, the interest rate should be 11.6%. (Answer)

It takes 6 days for both of them to have same number of followers

Solution:

Let "x" be the number of days

Celebrity A has 400 followers on social media and is gaining 75 followers each day

We can frame a equation as:

Celebrity A : 400 + 75(number of days)

Celebrity A : 400 + 75x --------- eqn 1

Celebrity B has 1,000 followers on social media, but is losing 25 followers a day

We can frame a equation as:

Celebrity B : 1000 - 25(number of days)

Here we use negative sign to denote losing of followers

Celebrity B : 1000 - 25x --------- eqn 2

For both of them to have same number of followers, eqn 1 must be equal to eqn 2

[tex]400 + 75x = 1000 - 25x\\\\\text{Solve the above equation for x}\\\\75x + 25x = 1000 - 400\\\\\text{Combine the like terms }\\\\100x = 600\\\\x = 6[/tex]

Thus it takes 6 days for both of them to have same number of followers

The equivalent expressions are:

[tex](x+y)^2 = x^2+2xy+y^2[/tex]

[tex](x+y)^2 = x(x+y)+y(x+y)[/tex]

[tex](x+y)^2 = (x+y)(x+y)[/tex]

[tex](x+y)^2=(y+x)^2[/tex]

Solution:

We have to find the equivalent expression for the given expression

Given expression is:

[tex](x+y)^2[/tex]

Let us first use the algebraic identity

[tex](a+b)^2=a^2+2ab+b^2[/tex]

Therefore,

[tex](x+y)^2 = x^2+2xy+y^2[/tex]

From above we get,

[tex](x+y)^2 = x^2+2xy+y^2[/tex]

2xy can be rewritten as xy + xy

Thus we get,

[tex]x^2+2xy + y^2 = x^2+xy+xy+y^2[/tex]

Group the terms we get,

[tex]x^2+2xy + y^2 = (x^2+xy)+(xy+y^2)[/tex]

Factor out "x" from first bracket and "y" from second bracket

[tex]x^2+2xy+y^2 = x(x+y)+y(x+y)[/tex]

Thus the equivalent expression is:

[tex](x+y)^2 = x(x+y)+y(x+y)[/tex]

[tex]\text{We know that } a^2 = a \times a[/tex]

Therefore,

[tex](x+y)^2 = (x+y)(x+y)[/tex]

By commutative property we know that,

[tex]a + b = b + a[/tex]

Therefore,

[tex](x+y)^2=(y+x)^2[/tex]

Thus the equivalent expressions are found
