find the surface area of a cube with side edges of 9in. show steps
Answer:
486 sq. in
Step-by-step explanation:
Find the area of one face
Area = s^2
s = 9 in
Area = 9^2
Area = 81
Area 6 sides
There are 6 sides to a cube. So if you have the area of 1 side, you need only multiply by 6 to get the area of the cube
Area = 6 * 81
Area = 486
Consider the arithmetic sequence 10,12,14,16 if n is an integer, which of these functions generate the sequence?
Given:
The arithmetic sequence is:
10, 12, 14, 16, ...
To find:
The function that generates the given sequence if n is an integer.
Solution:
We have,
10, 12, 14, 16, ...
Here, the first term is 10 and the common difference is:
[tex]d=a_2-a_1[/tex]
[tex]d=12-10[/tex]
[tex]d=2[/tex]
The nth term of an arithmetic sequence is:
[tex]a_n=a+(n-1)d[/tex]
Where, a is the first term, d is the common difference and [tex]n\geq 1[/tex].
Putting [tex]a=10,d=2[/tex] in the above formula, we get
[tex]a_n=10+(n-1)2[/tex]
[tex]a_n=10+2n-2[/tex]
[tex]a_n=8+2n[/tex]
Therefore, the function [tex]a_n=8+2n, n\geq 1[/tex] generates the sequence.

In Texas the state sales
tax rate is 6%. Beth
purchases a washing
machine at $420.00
and a dryer for
$360.00
How much will Beth's total be
including state sales tax
Answer: $826.8
Step-by-step explanation:
First, we add the amount of money that the machines sold for:
$420 + $360 = $780
Next, we multiply it by the sales tax, 6%,
$780 x 6%(0.06) = $46.80
Finally, we add this to the total:
$780 + $46.80 = $826.80
Alternatively, you can add the total sales and multiply by 106% using the 2-step method.

HELP IM GOING TO CRYY!!! Find the total area of the figure below. Round your answer to the nearest tenth.
Answer:
349.94
Step-by-step explanation:
First u add all the square sides because they all are the same which gives u 196 then u can see there is two half circles which if they add up will be a circle and the diameter is the same as the square sides then if the diameter is 14 then the radius will be 7 becaue 14/2 therefore u use the area of the circle which is
[tex]\pi \times {7}^{2} [/tex]
then u add all the numbers.

In a science experiment, a student concluded that a ray has to travel a distance from one corner at the top of the rectangular prism to the opposite side where the surface touching the floor is intersected. If the length, width, and height of the prism are given as 24 inches and 8 inches, 6 inches respectively, what is the distance travelled by the ray?
Answer:10
Step-by-step explanation:24-6-8=10
The distance travelled by the ray will be 26 inches. Then the correct option is B.
What is coordinate geometry?Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.
In a science experiment, a student concluded that a ray has to travel a distance from one corner at the top of the rectangular prism to the opposite side where the surface touching the floor is intersected.
If the length, width, and height of the prism are given as 24 inches and 8 inches, 6 inches respectively.
Then the distance travelled by the ray will be
We know the formula
D² = L² + W² + H²
We have
L = 24 in
W = 6 in
H = 8 in
Then the distance will be
D² = 24² + 6² + 8²
D² = 576 + 36 + 64
D² = 676
D = 26 in
Thus, the correct option is B.

Find the value of x.l
Answer:
The value of x is 28°
Step-by-step explanation:
2x + 1 and 33° together forms 90° angle.
So, we need to find the angle at the 2x + 1.
--> 90° - 33°
= 57°
So, 2x + 1 gives 57°.
So, to find x :-
2x + 1 = 57°
2x = 57 - 1
2x = 56
x = [tex]\frac{56}{2}[/tex]
x = 28
9. Hallar el perímetro de la figura sombreada.
Lado del cuadrado 6 m. (Las curvas son
semicircunferencias)
M
Respuesta:
Perímetro de la parte sombreada = (6pi + 24)
Explicación paso a paso:
Encuentra el diagrama adjunto
Primero necesitamos encontrar el perímetro de los semicírculos externos que sobresalen
Diámetro del semicírculo = 1/2 de la longitud del lado del cuadrado
Diámetro del semicírculo = 1/2 × 6 m = 3 m
Perímetro de los 4 semicírculos = 4 (pi d)
Perímetro de los 4 semicírculos = 4 × 3,14 × 3
Perímetro de los 4 semicírculos exteriores = 1
2pi cm
Para la parte interior sombreada = Perímetro de todo el cuadrado - Perímetro de semicírculo (2 cuadrantes)
Perímetro del cuadrado entero = 4 (6) = 24m
Perímetro de los 2 cuadrantes = pi d
Perímetro de los 2 cuadrantes = 6pi cm
Para la parte sombreada interior, perímetro = 24-6pi
Perímetro de la parte sombreada = 12pi + 24-6pi
Perímetro de la parte sombreada = (6pi + 24) cm
The president of a computer company must decide whether to place the company's new laptop on the market now or wait another year and continue with product testing.
The company's employees inform the president that if he releases the laptop now and no competitive devices enter the market, there will be a profit of $120,409.00; however, if he releases the laptop now and a competitive device enters the market, there will only be a small profit of $29,698.00. The company's employees also inform the president that if he waits another year and no competitive device enters the market, there will be a profit of $84,742.00; however, if he waits another year and a competitive device enters the market, there will be a loss of $59,396.00.
Suppose the company determines that there is a 22% chance that a competitive device will enter the market. What should the president do to maximize the expected profit over the next year?
Answer:
The president should release the new laptop now
Step-by-step explanation:
The profit if the new laptop is released now and no competitive device enters the market = $120,409.00
The profit if the new laptop is released now and a competitive device enters the market = $29,698
The profit if the new laptop is released in a years time and no competitive device enters the market = $84,742.00
The loss if the new laptop is released in a years time and a competitive device enters the market = $59,396.00
The chance that a competitive device will enter the market = 22%
∴ The chance that a competitive device will not enter the market = 1 - 22% = 78%
The expected increase in profit the company can make, compared to next year, if the new laptop is released and no competitive device enters the market = ($120,409.00 - $84,742.00) × 78% = $27,820.26
The expected increase in profit the company can make, compared to next year, if the new laptop is released and a competitive device enters the market = ($29,698.00 - $59,396.00)×0.22 = ($6,533.56) loss
Therefore, to maximize the expected profit over the next year, the president should release the new laptop now to make an expected profit of $27,820.26 over the next year.

is 8 yard, 9 yards, and 12 yards right triangle
Answer:
No
Step-by-step explanation:
you can check with the pythagorean theory
[tex]8^{2}+9^{2} =12^{2}[/tex]
64 + 81 = 144
145 = 144
this is not true, therefore those side lengths do not make a right triangle.
