Answer:
r = 4.24 inches
Step-by-step explanation:
Given that,
The surface area of the ball, A = 226.8 sq inches
The formula for the surface area of a sphere is given by :
[tex]A=4\pi r^2[/tex]
Where
r is the radius of the ball
[tex]r=\sqrt{\dfrac{A}{4\pi}} \\\\r=\sqrt{\dfrac{226.8}{4\pi}} \\\\r=4.24\ inch[/tex]
So, the radius of the ball is 4.24 inches.

Actually Welcome to the concept of Areas,
Let's divide the above map in to 2 parts , that is a rectangle and a triangle, and add both thier areas to get the area of the Nevada.
so we get as,
Area of triangle = 1/2*b*h
Area of triangle ==> 1/2*309*306 ==> 47277 mi^2
Area of rectangle = l*b = 205*309 ==> 63345 mi^2
Area of NEVADA = 47277 + 63345 = 110622 mi^2
hence the area = 110622 mi^2
Answer:
the approximate area of Nevada is 110,567 mi²

Some one help me solve for x
Answer:
x = 10
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
Sum the angles and equate to 360
9x + 15 + 85 + 90 + 80 = 360, that is
9x + 270 = 360 ( subtract 270 from both sides )
9x = 90 ( divide both sides by 9 )
x = 10

Look at the work for the following function. What mistake did they make when using the quadratic formula to find the solutions? What are the real solutions to the function?
Answer:
see below
Step-by-step explanation:
whenever there is negative number being squared, you need to add the brackets so that you inside the - 1 in front of the number
so this step is wrong
[tex] \sqrt{ - 9 { }^{2} - 4(1)(20) } [/tex]
the -9 ² , you must include the brackets to include the -1 in front of the 9
so it should be
[tex] \sqrt{( - 9) {}^{2} - 4(1)(20) } [/tex]
so you will get = 1
and then you continue with other parts of the formula and you will get real solutions

A technology company claims that 13% of customers who call the help desk cannot log in because they have their keyboard on caps lock, which blocks the log in process due to password case sensitivity. Brian, a help desk worker at this company, thinks this proportion is higher. The 95% confidence interval for the true proportion of customers who cannot log in due to caps lock is (0.128, 0.185). Is it reasonable to believe the true proportion of customers who cannot log in due to caps lock is greater than 13%?
Yes, because most of the values in the interval are above 0.13.
Yes, because the center of the interval is 0.1565, which is greater than 0.13.
No, because 0.13 is in the interval.
No, because there are values in the interval that are less than 0.13.
Answer:
It’s D for heaven sake !
No, because there are values in the interval that are less than 0.13.

2x - 4y = -2
2x + 3y = -16
What is the solution
Answer:
x=-5
y=-2
Step-by-step explanation:
equation 1 - equation 2
(2x-4y=-2) - (2x+3y=-16) = (-7y=14)
y=14/-7=-2
then substitute y=-2 into any equation
2x-4(-2)=-2
2x+8=-2
2x=-10
x=-10/2=-5

The tangent or tanθ in a right-angle triangle is the ratio of its perpendicular to its base. The value of x is 6.2 units.
What is Tangent (Tanθ)?The tangent or tanθ in a right-angle triangle is the ratio of its perpendicular to its base. it is given as,
[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
The base is the adjacent smaller side of the angle θ.
The value of x is,
x = AB - AC
x = 31(Tan 37°) - 31(Tan 29°)
x = 6.17659 ≈ 6.2 units.
Hence, the value of x is 6.2 units.

3) Write an explicit
formula for the
sequence:
45, 41, 37, 33
Answer and Step-by-step explanation:
f(n) = 45 - 4(n - 1)
This is the explicit formula for the sequence.
45 is the initial amount, which is why it is by itself.
The change in the sequence is take away 4, so this becomes a negative 4, which is then multiplied by (n - 1), where n is the term in the sequence.
