Help please !!!!!!!!!!!!!!!

Answer: It would equal 1/27.

Step-by-step explanation: Any number raised to a negative exponent, essentially means you reciprocal to get rid of the negative. After that, you do the math for the number in the denominator, without considering the negative sign. You could also do it the other way, do the function first without the negative, 3^3 is 27 and then applying the negative, reciprocal it to 1/27.

Answer:

First, solve for the volume of the tray by the equation V = L x W x H. Convert first all the dimensions to inches. The operation gives an answer of volume equal to 236.22 in³. Converting the amount of paint available to in³. This gives an answer of 231 in³. Hence, the answer is letter B.

Answer:

2.42

Step-by-step explanation:

First you need to use two points from store b to find the slope (y1-y2)/(x1-x2). I chose the first two points. (15.54-25.9)/(1.5-2.5)= 10.36. After you take another point from store b to plug into the equation y1-y2=m (x1-x2). M is the slope we just found and I used the first point.

Y1-15.54=10.36 (x1-1.5) distribute the 10.36 to the parentheses.

Y1-15.54=10.36x -15.54 get y1 by itself

Y=10.36x so store b is 10.36 a pound and store a is 7.94 a pound. 10.36-7.94= 2.42

Answer:

A) 72

Step-by-step explanation:

Okay well sice the lines AC and BD are parrallel that tells you that angles 4 is equal to 7 and angle 3 is equal to 8. Knowing this helps, now angle 3 and 4 have to equal 180 degrees cause it a strioght line. so do 180 - 108 (angle 3) equals angle 4. Once you find angle 4 degrees its the same as angle 7.

Answer:

[tex]x = 45[/tex]

Step-by-step explanation:

See attachment for complete question.

From the attachment, we have that x and 3x are on a straight line

and angle on a straight line sum up to 180

In other words:

[tex]x + 3x = 180[/tex]

[tex]4x = 180[/tex]

Divide through by 4

[tex]\frac{4x}{4} = \frac{180}{4}[/tex]

[tex]x = \frac{180}{4}[/tex]

[tex]x = 45[/tex]

Hence, the measure of x is 45 degrees

Step-by-step explanation:

it is Arithmetic because if you subtract 12 from 40 you'll get 28 , same for the others. but if you get the common ratio by dividing 40/12 which is 3.333... it's doent work for the sequence

Answer/Step-by-step explanation:

According to the centroid theorem, the X is ⅔ of the distance from each vertex to the midpoint of the opposite side.

Thus:

1. If CW = 15,

CX = ⅔*(15)

CX = 10

XW = ⅓*(15)

XW = 5

2. If BX = 8,

BX = ⅔*BY

3*BX = 2*BY

(3*BX)/2 = BY

(3*8)/2 = BY

24/2 = BY

12 = BY

BY = 12

XY = ⅓*BY

XY = ⅓*12

XY = 4

3. If XZ = 3, find AX and AZ.

XZ = ⅓*AZ

XZ*3 = AZ

3*3 = AZ

9 = AZ

AZ = 9

AX = ⅔*AZ

AX = ⅔*9

AX = 6

X=3 and just use Photomatix on your phone

Answer:

3m/s

Step-by-step explanation:

delta y = 40m - 10m = 30m

delta x = 20s - 10s = 10s

slope = delta y / deltax = 30m / 10s = 3m/s

Answer:

PR = 15

Step-by-step explanation:

            PR = PQ + QR

   10x - 45 = 3 + x + 6  {Combine like terms}

   10x - 45 = 9 + x             {Subtract 'x' from both sides}

10x - x - 45 = 9

      9x - 45 = 9                  {Add 45 to both sides}

             9x  = 9 +45

             9x = 54

               x = 54/9

x = 6

PR = 10x - 45

     = 10*6 - 45

     = 60 - 45

PR = 15

Answer:

Monica paid $171 while Rachel paid $207

Step-by-step explanation:

We are told that Monic and Rachel purchased a tv for $378.

Let the amount spent by Monica be X and the amount spent by Rachel be Y.

Thus;

x + y = 378 - - - - (eq 1)

We are told that Monica paid $36 less then Rachel. Thus;

y = x + 36

Or y - x = 36 - - - (eq 2)

Add eq 1 & eq 2 together to give;

2y = 378 + 36

2y = 414

y = 414/2

y = $207

Put 207 for x in eq 1 to get;

x + 207 = 378

x = 378 - 207

x = $171

Thus;

Monica paid $171 while Rachel paid $207

Answer:

Step-by-step explanation:

-0.59x+0.29=7.2

-0.59x+0.29-0.29=7.2-0.29

-0.59x=7.2

divide both sides by -0.59

x=− 11.7118644

that can be rounded to x= -11.7

Answer:

x=-11.7

Step-by-step explanation:

-0.59x+0.29=7.2

subtract 0.29 on both sides to isolate x

-0.59x=6.91

divide -0.59 from both sides (will be a large number)

-11.711864

x=-11.7

Answer:

(a) 0.90

(b) 0.9001

Step-by-step explanation:

[tex]X_{i}\sim N(50, 100);\ i=1,2,3...16[/tex]

(a)

[tex]P ( 796.2 < \sum\limits^{16}_{i=1}{(X_{i} - 50)^{2} < 2630)=P ( \frac{796.2}{100} < \sum\limits^{16}_{i=1}{(\frac{X_{i} - 50}{10})^{2} < \frac{2630}{100})[/tex]

                                                    [tex]=P ( 7.962 < \sum\limits^{16}_{i=1}{Z_{i}^{2} < 26.3)\\=P ( 7.962\leq \chichi^{2}_{16} \leq 26.3)\\\\=P(\chi^{2}_{16}\leq 26.3)-P(\chi^{2}_{16}\leq 7.962)\\\\=0.90[/tex]

*Use the chi-square table.

(b)

[tex]P ( 726.1< \sum\limits^{16}_{i=1}{E(X_{i}-\bar X)^{2} < 2500)=P ( \frac{726.1}{100} < \frac{(n-1)S^{2}}{\SIGMA^{2}}< \frac{2500}{100})[/tex]

                                                    [tex]=P ( 7.261\leq \chi^{2}_{16-1} \leq 25.0)\\\\=P(\chi^{2}_{15}\leq 25.0)-P(\chi^{2}_{15}\leq 7.261)\\\\=0.9001[/tex]

*Use the chi-square table.

Answer:

-324

Step-by-step explanation:

First, you need to just multiply the two numbers together.

36 * 9

This would give you the overall answer. Then you determine if when you multiply the numbers, if you'd need to add the integer, a.k.a, the negative sign.

Since when you multiply a negative and a positive, the answer will be negative.

So, 36 * (-9) = -324
