I don't get what I'm doing wrong,does anybody know this?The diameter of a great circle is 24 inched find the total surface area of the hemisphere don't forget to include the base in the total area.
since it's diameter is 24, its radius must be 12.
[tex]\textit{surface area of a sphere}\\\\ SA=4\pi r^2 ~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=12 \end{cases}\implies SA=4\pi (12)^2\implies SA=576\pi[/tex]
now, that's for a sphere, for a hemisphere with the same radius it'd just be half that or 288π, now let's add the area of the circular base.
[tex]\stackrel{\textit{\LARGE Areas}}{\stackrel{hemisphere}{288\pi} ~~ + ~~\stackrel{circular~base}{\pi (12)^2}}\implies 288\pi ~~ + ~~144\pi \implies 432\pi[/tex]
The total surface area of the hemisphere is 288π. The area that include both surface area of hemisphere and the base of the total area is 432π.
What is hemisphere?
A hemisphere is "half the part of sphere".
According to the question,
The diameter of greater circle is 24 this implies radius of circle is 12.
Surface area of sphere = 4πr²
= 4×π × (12)²
= 576π.
Surface area of sphere is 576π
Surface area of Hemisphere is half of the surface area of sphere.
(576π)/2 = 288π
In order to include the base in the total area only if add surface area of hemisphere and area of circle.
surface area of hemisphere + rea of circle = 288π + π(r)²
= 288π + π(12)²
= 288π + 144π
= 432π
Hence, the total surface area of the hemisphere is 288π. The area that include both surface area of hemisphere and the base of the total area is 432π.

Line A is represented by the equation given below: x + y = 2 What is most likely the equation for line B, so that the set of equations has infinitely many solutions? (1 point) a 2x + 2y = 2 b 2x + 2y = 4 c 2x + y = 2 d x + y = 4
The set of the equations x + y = 2 and 2x + 2y = 4 have infinitely many solutions, option (b) is correct.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
equation of the line:
x + y = 2
a) 2x + 2y = 2 ⇒ x + y = 1
b) 2x + 2y = 4 ⇒ x + y = 2
c) 2x + y = 2 ⇒ 2x + y = 2
d) x + y = 4 ⇒ x + y = 4
The given equation and equation (b) 2x + 2y = 4 ⇒ x + y = 2 has the same coefficient of x and y as well as same constant it means the set of the equations have infinitely many solutions
Thus, the set of the equations x + y = 2 and 2x + 2y = 4 have infinitely many solutions option (b) is correct.

Answer:
2 hours and 44 min. or 2.7273 hours
Step-by-step explanation:
Ryan: 1 hole per 5 hours
Castel: 1 hole per 6 hours
x = time if working together then
x(1/5 + 1/6) = 1
x(6 + 5) = 30
11x = 30
x = 30/11
x = 2.7273 hours

If , the ratio of the length of to the length of is .
Given the ratio of 5 : 3, the length of the rectangle is 45 units
How to determine the length?The ratio is given as:
Length : Width = 5 : 3
The perimeter is given as:
Perimeter = 144
The perimeter of a rectangle is:
Perimeter = 2 * (Length + Width)
So, we have:
2 * (Length + Width) = 144
Divide both sides by 2
Length + Width = 72
Recall that:
Length : Width = 5 : 3
Express as fraction
Length/Width = 5/3
Make Width the subject
Width = 3Length/5
Substitute Width = 3Length/5 in Length + Width = 72
Length + 3Length/5 = 72
Multiply through by 5
5Length + 3Length = 360
This gives
8Length = 360
Divide both sides by 8
Length = 45
Hence, the length of the rectangle is 45 units

Relation between sugar and flour
18 teaspoons of sugar per 3 cups of flourRate : 18/3 = 6 teaspoons of sugar per cup of flourTable
[tex]\left[\begin{array}{ccc}sugar(tsp)&flour(cups)\\12&2\\18&3\\36&6\\48&8\\54&9\end{array}\right][/tex]
Answer:
Step-by-step explanation:
Remark
The key to this question is the second entry. Numerically the sugar is divided by 6 to get the flour. Never mind the units. Just deal with the ratio itself.
Formula
Flour = Sugar / 6
Solution
Sugar = 12
Flour = 12/6 = 2
Flour = 18/6
Flour = 3
Flour = 6
6 = sugar/6 multiply by 6
6*6 = 6* sugar/6
36 = sugar
Sugar = 48
Flour = 48/6 = 8 cups of flower
Flour = 9
9 = sugar / 6
9*6 = sugar
Sugar = 54.

{3, 4, 5, 6}
Step-by-step explanation:Inequalities represent the value of a variable by comparing them to other values.
Inequality Signs
Before answering the question, make sure you understand the different inequality signs.
< - This sign represents less than. This means that the value on the left is less than the value on the right.> - This sign represents greater than. This means that the value on the left is greater than the value on the right.< - This sign means less than or equal to. So, the value on the left will be less than or the same as the value on the right.> - This sign means greater than or equal to. So, the value on the left will be greater than or the same as the value on the right.Solving the Inequality
To make this question easier to answer, we can solve the inequality. Solving an inequality involves isolating the variable.
To do this subtract 19 from both sidesx < 9Finding the Set
Now that we solved the inequality we can look for the correct set of numbers. Since we solved the inequality, we know that all of the correct values should be less than 9. However, because there was no equal to sign, 9 is not included in the set. The only set that has only correct solutions is {3, 4, 5, 6}.
