Bbbbbbbbbbb????????????!??!

Can anyone solve the circled numbers?If not just please solve whatever you can.Im so tired

EastWind [94]

Answer:

36. The absolute value of |97| is 97. Remember, the absolute value of a number is how far away the number is from zero.

40. I think that says |-23/56| .... if so, I'm pretty sure you can just say 23/56... not too sure though. Because, yes, technically this number is 23/56 away from zero... just not sure if that is the final way you should answer.

44. Answer: Wayne, MI (-0.2)

Explain: Wayne, MI had the least percent change in pop. because it is the closest option to 0, it only decreased 0.2 percent.

48.

|43-4a| + 51

|43-4(6)| + 51

|43-24| + 51

|19| + 51

19 + 51

=70

52.

7.4 + |y-2.6|

7.4 + |3.2-2.6|

7.4 + |0.6|

7.4 + 0.6

56.

|-c| + (2+1/2)

|-5/4| + (2+1/2)

|5/4| + (2+1/2)

|1 1/4| + (2+1/2)

1 1/4 + (2+1/2)

1 1/4 + (2 1/2)

1 1/4 + 2 1/2

1 1/4 + 2 2/4

=3 3/4

That is all I can do for you! I hope I helped :)

A newspaper carrier has $3.65 in change he has four more quarters then dimes but two times as many nickels as quarters how many

77julia77 [94]

Answer:

The number of quarter coins is 9, the number of dime coins is 5 and the number of nickel coins is 18

Step-by-step explanation:

Let

x ----> the number of quarter coins

y ---> the number of dime coins

z ---> the number of nickel coins

Remember that

$1\ quarter=\$0.25$

$1\ dime=\$0.10$

$1\ nickel=\$0.05$

we know that

$0.25x+0.10y+0.05z=3.65$ ----> equation A

$x=y+4$

$y=x-4$ ----> equation B

$z=2x$ ----> equation C

Solve the system by substitution

substitute equation B and equation C in equation A

$0.25x+0.10(x-4)+0.05(2x)=3.65$

solve for x

$0.25x+0.10x-0.40+0.10x=3.65$

$0.45x=3.65+0.40$

$0.45x=4.05\\x=9$

Find the value of y

$y=x-4$

substitute the value of x

$y=9-4=5$

Find the value of z

$z=2x$

$z=2(9)=18$

therefore

The number of quarter coins is 9, the number of dime coins is 5 and the number of nickel coins is 18

$\large \bigstar \frak{ } \large\underline{\sf{Solution-}}$

Consider, LHS

$\begin{gathered}\rm \: \dfrac { \tan \theta + \sec \theta - 1 } { \tan \theta - \sec \theta + 1 } \\ \end{gathered}$

We know,

$\begin{gathered}\boxed{\sf{ \:\rm \: {sec}^{2}x - {tan}^{2}x = 1 \: \: }} \\ \end{gathered} \\ \\ \text{So, using this identity, we get} \\ \\ \begin{gathered}\rm \: = \:\dfrac { \tan \theta + \sec \theta - ( {sec}^{2}\theta - {tan}^{2}\theta )} { \tan \theta - \sec \theta + 1 } \\ \end{gathered}$

We know,

$\begin{gathered}\boxed{\sf{ \:\rm \: {x}^{2} - {y}^{2} = (x + y)(x - y) \: \: }} \\ \end{gathered} \\$

So, using this identity, we get

$\begin{gathered}\rm \: = \:\dfrac { \tan \theta + \sec \theta - (sec\theta + tan\theta )(sec\theta - tan\theta )} { \tan \theta - \sec \theta + 1 } \\ \end{gathered}$

can be rewritten as

$\begin{gathered}\rm\:=\:\dfrac {(\sec \theta + tan\theta ) - (sec\theta + tan\theta )(sec\theta -tan\theta )} { \tan \theta - \sec \theta + 1 } \\ \end{gathered} \\ \\ \\\begin{gathered}\rm \: = \:\dfrac {(\sec \theta + tan\theta ) \: \cancel{(1 - sec\theta + tan\theta )}} { \cancel{ \tan \theta - \sec \theta + 1} } \\ \end{gathered} \\ \\ \\\begin{gathered}\rm \: = \:sec\theta + tan\theta \\\end{gathered} \\ \\ \\\begin{gathered}\rm \: = \:\dfrac{1}{cos\theta } + \dfrac{sin\theta }{cos\theta } \\ \end{gathered} \\ \\ \\\begin{gathered}\rm \: = \:\dfrac{1 + sin\theta }{cos\theta } \\ \end{gathered}$

<h2>Hence,</h2>

$\begin{gathered} \\ \rm\implies \:\boxed{\sf{ \:\rm \: \dfrac { \tan \theta + \sec \theta - 1 } { \tan \theta - \sec \theta + 1 } = \:\dfrac{1 + sin\theta }{cos\theta } \: \: }} \\ \\ \end{gathered}$

-x^4y^2+7x^3y^3-3xy^5+2x^2y^4 in descending powers of x

muminat

Answer:

-x^4y^2 +7x^3y^3 +2x^2y^4 -3xy^5

Step-by-step explanation:

The powers of x in the terms of the given expression are ...

4, 3, 1, 2

so, we want to swap the last two terms to put them in the desired order:

-x^4y^2 +7x^3y^3 +2x^2y^4 -3xy^5
