Answer:

There are 33 girls in choir

Step-by-step explanation:

4 x 11 = 44 (we get four from the 1 boy for every 4 girls)

assuming that we have 44 kids in the class, 1/4 will be boys. 44/4 = 11 which means that we subtract 11 from 44 which will get you 33.

You have ​$23 comma 000 to​ invest, part at 8 % and the rest at 9 %. If x is the amount invested at 8 %​, write an algebraic exp
Vinvika [58]

<em>x</em> = amount invested at 8 %. Then 23 000 - <em>x</em> = amount invested at 9 %

Annual income (<em>I</em>) = interest at 8 % + interest at 9 %

<em>I</em> = 0.08<em>x</em> + 0.09(23 000 – <em>x</em>)

<em>I</em> = 0.08<em>x</em> + 2070 – 0.09<em>x</em>

<em>I</em> = 2070 – 0.01<em>x</em>

Determine all critical points the the function:

\bf y=x^2-32\sqrt{x}\implies \cfrac{dy}{dx}=2x-32\cdot \cfrac{1}{2}x^{-\frac{1}{2}}\implies \cfrac{dy}{dx}=2x-\cfrac{32}{2\sqrt{x}}&#10;\\\\\\&#10;\cfrac{dy}{dx}=2x-\cfrac{16}{\sqrt{x}}\implies \cfrac{dy}{dx}=\cfrac{2\sqrt{x^3}-16}{\sqrt{x}}\\\\&#10;-----------------------------\\\\

\bf 0=\cfrac{2\sqrt{x^3}-16}{\sqrt{x}}\implies 0=2\sqrt{x^3}-16\implies 16=2\sqrt{x^3}&#10;\\\\\\&#10;8=\sqrt{x^3}\implies 2^3=\sqrt{x^3}\implies (2^3)^2=x^3\implies (2^6)^{\frac{1}{3}}=x&#10;\\\\\\&#10;2^{\frac{2}{1}}=x\implies \boxed{4=x}\\\\&#10;-----------------------------\\\\&#10;\textit{the other critical point at }\sqrt{x}=0\implies \boxed{x=0}

Identify the pattern for the following sequence. Find the next three terms in the sequence.
Zina [86]
The answer is B.

-9/3= -3, which means that each number is getting multiples by -3. Therefore, we can eliminate A and D. 27•-3=-81, so we can eliminate C. We are left with B, and we can check this by making sure that each number is correctly multiplied by -3.

Which equation shows the result of substituting and expression for y from the first equation into the second equation for the gi
krek1111 [17]

Answer:

x-2x = -3 and x = 3

Step-by-step explanation:

Given the expression

y=x+5.... 1

y-2x=2.... 2

Substituting the first equation into the second we will have;

From 2;

y -2x = 2

x+5-2x = 2

x-2x +5 = 2

x-2x = 2-5

x-2x = -3

-x =-3

x =3

Hence the required equation is x-2x = -3 and x = 3
