If I passed out math books and the length is 10 inches the. Width is 8 inches.What is the perimeter of each book

Answer:

10

Step-by-step explanation:

after substituting in the values of each variable, the expression becomes..

3 + (-2) - (-9)

= 3 - 2 - (-9)

= 1 - (-9)

= 1 + 9 = 10

Answer:

i am pretty sure its B..............

Hi!

The point-slope formula looks like this:

y-y1=m(x-x1)

in this case

y1=1

m=-4

x1=-3

plug in the values

[tex]\boxed{\boxed{\bold{y-1=-4(x-(-3)}}}[/tex]

Note:

For Point-Slope Form, we use a point that the line passes through and the slope of the line.

Actually, that's why it's called "Point-Slope Form" right? =)

Hope everything is clear.

Let me know if you have any other questions; if so, please feel free to use the comment section.

Answer: 198cm

Step-by-step explanation:

We are given the dimensions of a rectangular prism;

3cm 9cm and 6cm

We are required to determine its surface area;

We need to know that;

Surface area of a rectangular prism is given by;

A = 2(WL+HL+WH)

Where L, W and H are length , width and height respectively;

Assuming;

Width is 3 cm

Length is 9 cm, and

Height is 6 cm

Then;

Area = 2 ( (3×9) + (6×9) + (3×6))

       = 2(99)

      = 198 cm²

Therefore, the area of the rectangular prism is 198 cm²

Answer:

x − 4x + 6y + (14x − 5y) ⇔ 11x+y

(5x − 3y) − x + 3x − 5y ⇔ 7x-8y

5(x + y) + 6(x − y) ⇔ 11x-y

3x + 3y + 2(2x − y)  ⇔  7x+y

Step-by-step explanation:

Solve the following;

3x + 3y + 2(2x − y)

4(x + y) − 3(x + y)

x − 4x + 6y + (14x − 5y)

(5x − 3y) − x + 3x − 5y

Answer:

a triangle witih side lengths of 12,16,20

To solve linear equations, we must perform inverse operations on both sides of the equal sign to cancel values out.

We perform inverse operations to combine like terms. This means to get x to one side and everything else on the other.

[tex]5x+7=15[/tex]

Because 7 is being added to x, subtract it from both sides:

[tex]5x+7-7=15-7\\5x=8[/tex]

Because x is being multiplied by 5, divide both sides by 5:

[tex]\dfrac{5x}{5}=\dfrac{8}{5}\\\\x=\dfrac{8}{5}[/tex]

Therefore. [tex]x=\dfrac{8}{5}[/tex].

[tex]7x+4=5x-18[/tex]

Here, we can group all the x values on the left side of the equation. Subtract 5x from both sides:

[tex]7x+4-5x=5x-18-5x\\2x+4=-18[/tex]

To isolate x, subtract 4 from both sides:

[tex]2x+4-4=-18-4\\2x=-22[/tex]

Divide both sides by 2:

[tex]\dfrac{2x}{2}=\dfrac{-22}{2}\\\\x=-11[/tex]

Therefore, [tex]x=-11[/tex].

Answer:

Which expression is NOT equivalent to -20? O A (-80) 4 80 В — (0) ОО с (30) 80 ор 80 (-4 -

Step-by-step explanation:

Answer:

answer is 90° - 80° = 10° because each quartile equals 90°

Answer:

First step : State the null and the alternative hypothesis

   The null hypothesis is  [tex]H_o : \mu = 3.5 \ hours[/tex]

    The alternative hypothesis is  [tex]H_a : \mu > 3.5 \ hours[/tex]

Second Step : Calculate the test statistics

   Generally the test statistics is mathematically represented as

             [tex]z = \frac{\= x - \mu }{\frac{\sigma }{\sqrt{n} } }[/tex]

=>           [tex]z = \frac{3.75 - 3.5 }{\frac{0.7 }{\sqrt{45} } }[/tex]

=>           [tex]z  =  2.11[/tex]

Third Step  : Obtain the p-value

Generally from the z-table the probability of  z  =  2.11 is

    [tex] P(Z  >  2.11) =  0.0174[/tex]

Fourth Step : Compare the p-value with the level of significance and state the decision rule and the conclusion

From the obtained value  the [tex]p-value  <  \alpha[/tex] hence

 The decision rule is  

The null hypothesis is rejected

 The conclusion is

There is sufficient evidence to conclude that average of the laptop batteries is more than 3.5 hours of use per charge

Step-by-step explanation:

From the question we are told that

  The population mean is [tex]\mu = 3.5 \ hours[/tex]

   The sample size is  n =  45

   The standard deviation is  [tex]\sigma = 0.7 \ hours[/tex]

   The sample mean is  [tex]\= x = 3.75[/tex]

    The level of significance is  [tex]\alpha = 0.05[/tex]

First step : State the null and the alternative hypothesis

   The null hypothesis is  [tex]H_o : \mu = 3.5 \ hours[/tex]

    The alternative hypothesis is  [tex]H_a : \mu > 3.5 \ hours[/tex]

Second Step : Calculate the test statistics

   Generally the test statistics is mathematically represented as

             [tex]z = \frac{\= x - \mu }{\frac{\sigma }{\sqrt{n} } }[/tex]

=>           [tex]z = \frac{3.75 - 3.5 }{\frac{0.7 }{\sqrt{45} } }[/tex]

=>           [tex]z  =  2.11[/tex]

Third Step  : Obtain the p-value

Generally from the z-table the probability of  z  =  2.11 is

    [tex] P(Z  >  2.11) =  0.0174[/tex]

Fourth Step : Compare the p-value with the level of significance and state the decision rule and the conclusion

From the obtained value  the [tex]p-value  <  \alpha[/tex] hence

 The decision rule is  

The null hypothesis is rejected

 The conclusion is

There is sufficient evidence to conclude that average of the laptop batteries is more than 3.5 hours of use per charge

Answer:

x = 13; y = 13; z = 18

Step-by-step explanation:

In a rhombus, opposite angles are congruent and consecutive angles are supplementary.

6x + 8 = 86

6x = 78

x = 13

7y + 3 + 86 = 180

7y + 89 = 180

7y = 91

y = 13

5z + 4 + 86 = 180

5z + 90 = 180

5z = 90

z = 18
