Answer:

 area of the square pyramid = a2+ 2al (or) a2+2a √a24+h2 a 2 4 + h 2 .

Step-by-step explanation:

The surface area of a square pyramid is the sum of the areas of all its 4 triangular side faces with the base area of the square pyramid. If a, h, and l are the base length, the height of the pyramid, and slant height respectively, then the surface area of the square pyramid = a2+ 2al (or) a2+2a √a24+h2 a 2 4 + h 2 .

Answer:

You would need 48

Step-by-step explanation:

divide 36.00/0.75

Answer:

so Area = length x width

Area = 450,  width = 9

450 = 9 x length

divide 450 by 9, and you have the length.

Perimeter = length + length+ 9 + 9

and you got your perimeter!

Answer:

1. 1/2 and 2/4

2. They are equivalent because it you put them in simplest form they are going to be equal

3. No

4. They are not equivalent because 1/8 and 1/5 isn't the same so they aren't going to be equal

Answer:

Step-by-step explanation:

Ice forms when the temperature of water reaches 32 degrees Fahrenheit (0 degrees Celsius). When you add salt, that temperature drops: A 10-percent salt solution freezes at 20 °F (-6 °C), and a 20-percent solution freezes at 2 °F (-16 °C). On a roadway, this means that if you sprinkle salt on the ice, you can melt it.

Answer:

0.25 or 5/12 - 1/6

Step-by-step explanation:

-1/2(-5/6+1/3), do PMDAS. (-5/6) = -0.833 (repeated) and (1/3) = 0.333 (repeated) and you add them both (-0.833 + 0.333) = -0.5 and -1/2 = -0.5 and when you multiply them both it would equal 0.25. or another explanation for the answer is 5/12 = 0.41666666666 and 1/6 = 0.16666666666 and when you subtract them both you get 0.25, I hope this was helpful.

Step-by-step explanation:

Area of a garden = 104 m^2

Area of a garden = 104 m^2Area of a pond = 56 m^2

Percentage of the garden that is used to make the pond

= (56/104) × 100%

= 53.8%

Answer:

Step-by-step explanation:

Let consecutive odd integers be (2x + 1) and (2x + 3)

Their reciprocals are [tex]\frac{1}{2x + 1 }[/tex]    and [tex]\frac{1}{2x + 3 }[/tex]

[tex]\frac{1}{2x+1}+\frac{1}{2x+3}=\frac{44}{483}\\\\\frac{1*(2x+3)}{(2x+1)(2x+3)}+\frac{1*(2x+1)}{(2x+3)(2x+1)}=\frac{44}{483}\\\\\frac{2x + 3 + 2x +1}{(2x + 1)(2x+3)}=\frac{44}{483}\\\\\frac{4x + 4}{4x^{2}+8x+3}=\frac{44}{483}\\[/tex]

483*(4x+4) = 44*(4x² + 8x + 3)

483*4x + 483*4 = 44*4x² + 44*8x  + 44*3

1932x + 1932 = 176x² + 352x + 132

176x² + 352x + 132 -1932x - 1932 = 0      

Combine like terms

176x² + 352x - 1932x - 1932 + 132 = 0

176x² - 1580x - 1800 = 0

Divide the equation by 4

44x² - 395x - 450 = 0

C. (5.097, 7.404)

Step-by-step explanation:

EDGE 2020

The 90% confidence interval for the true mean amount of time teenagers from this town watch sports is (5.097, 7.404).

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

The formula for the confidence interval is:

CI = x ± tα/2 × (s/√n)

where x is the sample mean,

s is the sample standard deviation,

n is the sample size, and

tα/2 is the t-value with (n-1) degrees of freedom and a confidence level of 90%.

From data (x) is 6.25 hours and

s=  4.33 hours.

We also know the sample size (n) is 40.

To find the t-value with (n-1) degrees of freedom and a confidence level of 90%, we can use a t-table.

For 39 degrees of freedom and a confidence level of 90%

Let us find that the t-value is 1.684.

Substituting the values we have into the formula, we get:

CI = 6.25 ± 1.684 × (4.33/√40)

CI = (5.097, 7.404)

Therefore, the 90% confidence interval for the true mean amount of time teenagers from this town watch sports is (5.097, 7.404).

Answer:

Angle = A

A7 = A4 (Alternate interior angles)

A14 = A11 (Vertically opposite angles)

A11 = A6(Corresponding angles)

A4 = A14 (Given)

From this, we can get A6 = A4

A6 and A4 are alternate angles and are equal. So c and d are parallel.

A7 + A10 = 180 (Linear pair of angles) - ( 1 )

A13 = A10(Alternate interior angles)

Putting A13 in place of A10 in ( 1 ),

A7 + A13 = 180

Hence proved
