Step-by-step explanation:
The question has missing details; as the radius or an attachment of the hemisphere is not given.
However, I'll solve on a general terms.
The volume of a hemisphere is: [tex]V = \frac{2}{3}\pi r^3[/tex]
Take for instance
[tex]r = 14.9cm[/tex]
The volume becomes:
[tex]V = \frac{2}{3} * 3.142 * 14.9^3[/tex]
[tex]V = \frac{2 * 3.142 * 14.9^3}{3}[/tex]
[tex]V = \frac{20787.151516}{3}[/tex]
[tex]V = 6929.051cm^3[/tex]
So, all you need to do is plug in the value of radius in the formula.

The equation p = −5x2 + 100x − 250 models the profit p in dollars from selling pizza, where x is the price per pizza in dollars. What is the highest price you can charge per pizza to profit $100?
The highest price per pizza in a profit of $100 is approximately $15.48
The profit equation is given by:
p = -5 [tex]x^2[/tex] + 100x - 250
Substitute p = 100 and solve for "x":
100 = -5 [tex]x^2[/tex]+ 100x - 250
To solve this quadratic equation, it can be rearranged it to standard form [tex](ax^2 + bx + c = 0)[/tex]
[tex]5x^2- 100x + 350 = 0[/tex]
Now, we can solve the quadratic equation using the quadratic formula:
[tex]x = \dfrac{(-b\pm \sqrt ({b^2 - 4ac)}}{2a}[/tex]
In our equation, a = 5, b = -100, and c = 350. Substitute these values into the formula:
x =[tex]\frac{(\sqrt{(-100)^2 - 4 \times 5 \times 350}}{2\times5}[/tex]
x= [tex]\dfrac{{100 \pm\sqrt{3000}}}{10}[/tex]
Thus, the two possible solutions for "x":
[tex]x_1[/tex] =[tex]\dfrac{100 + \sqrt{3000}}{10}[/tex]
[tex]x_2[/tex] =[tex]\dfrac{100 - \sqrt{3000}}{10}[/tex]
Calculating the values:
[tex]x_1[/tex]≈ 15.48
[tex]x_2[/tex] ≈ 4.23
The highest price per pizza that results in a profit of $100 is approximately $15.48 (rounded to two decimal places).

Devon waxes 1/2 of his car with 1/3 bottle of car wax. At this rate, what fraction of the bottle will Devon use to wax his entire car?
Answer:
2/3 bottle of car wax
Step-by-step explanation:
If Devon waxes 1/2 of his car with 1/3 bottle of car wax then he only has half of his car to finish. Since 1/2 of his car used 1/3 of wax then the other half will only take 1/3 of car wax.

[tex]x=16.4\ y=13.7[/tex]
Step-by-step explanation:
[tex][Kindly\ refer\ the\ attachment.]\\We\ are\ given\ that,\\\triangle ABC\ is\ a\ right-triangle\ and\ has\ it's\ legs\ x\ and\ z.\\It's\ altitude\ CD\ separates\ it\ into\ two\ triangles:\\\triangle BCD\ and\ \triangle ADC,\ both\ of\ which\ are\ right-triangles.\\Now,\\The\ Pythagoras\ Theorem\ tells\ us\ that:\\'The\ sum\ of\ squares\ of\ both\ the\ legs\ is\ equal\ to\ the\ square\ of\ the\\ hypotenuse'.\\Here,\\Lets\ consider\ three\ triangles\ separately.\\[/tex]
[tex]In\ \triangle ADC\ right\ angle\ is\ at\ \angle ADC.\\Hence,\\AC\ is\ the\ hypotenuse, and\ AD\ and\ DC\ are\ it's\ legs.\\Hence,\\AD^2+DC^2=AC^2\\Or,\\9^2+y^2=x^2\\\\Lets\ take\ the\ above\ equation\ as\ E_1.[/tex]
[tex]In\ \triangle BDC\ right\ angle\ is\ at\ \angle BDC.\\Hence,\\BC\ is\ the\ hypotenuse, and\ DC\ and\ DB\ are\ it's\ legs.\\Hence,\\DC^2+DB^2=BC^2\\Or,\\21^2+y^2=z^2\\Lets\ take\ the\ above\ equation\ as\ E_2.[/tex]
[tex]Now,\\In\ whole\ \triangle ACB\ right\ angle\ is\ at\ \angle ACB.\\Hence,\\AB\ is\ the\ hypotenuse, and\ AC\ and\ BC\ are\ it's\ legs.\\Hence,\\AC^2+BC^2=AB^2\\Or,\\x^2+z^2=(21+9)^2=30^2\\Lets\ take\ the\ above\ equation\ as\ E_3.[/tex]
[tex]Lets\ now\ gather\ the\ three\ equations:\\9^2+y^2=x^2\\21^2+y^2=z^2\\x^2+z^2=30^2\\Now,\\Lets\ pair\ and\ add\ E_1\ and\ E_2.\\Hence,\\(9^2+y^2)+(21^2+y^2)=(x^2)+(z^2)\\Hence,\\81+y^2+441+y^2=x^2+z^2\\Hence,\\2y^2+522=x^2+z^2\\Considering\ E_3,\\We\ already\ know\ that,\\x^2+z^2=30^2\\Hence,\\2y^2+522=30^2\\Hence,\\2y^2+522=900\\2y^2=900-522=378\\Hence,\\y^2=\frac{378}{2}=189\\Hence,\\y=\sqrt{189}=13.7\\[/tex]

Answer:
[tex]\frac{-24p + 5}{30p}[/tex]
Step-by-step explanation:
Did you mean to add the terms. You can only solve equations or inequalities and this is an expression. Assuming you are to add the terms, then the lowest common denominator is 30p
So, [tex]\frac{-2(10)}{3p(10)} + \frac{6p}{5(6p)} - \frac{30p}{30p} + \frac{5(5)}{6p(5)}[/tex]
= [tex]\frac{-20 + 6p - 30p + 25}{30p}[/tex]

Solve the system
9x^2 + 4(y - 2)^2 = 36
x^2 = 2y
Answer: y = 2 and x = 2
Step-by-step explanation:
[tex]9x^2+4(y-2)^2=36\\x^2=2y[/tex]
First, get the entire thing in terms of y, because you cant solve for two variables at the same time. They gave us the fact that x^2 = 2y
[tex]9(2y)+4(y-2)^2=36\\18y+4(y^2-4y+4)=36\\18y+4y^2-16y+16=36\\4y^2+2y-20=0[/tex]
What two numbers multiply to equal -80 but add to equal 2? That is +10 and -8.
[tex]4y^2+2y-20=0\\(4y^2-8y)+(10y-20)=0\\4y(y-2)+10(y-2=0)\\(4y+10)(y-2)=0\\y=-5/2\\y=2[/tex]
Now solve for x by plugging in y to the easier equation
[tex]x^2=2(-5/2)\\x\neq \sqrt{-5}[/tex]
If I didn't make a mistake, this should be the only answer. In the case of y = -5/2, you would get an imaginary x-value. Therefore y cannot equal -5/2
[tex]x^2=2(2)\\x=2[/tex]
The solution of the expression are,
x = 2.28 , y = 2.62
Or, x = 3.9i , y = - 7.62
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The system of equations are,
9x² + 4 (y - 2)² = 36 .. (i)
x² = 2y .. (ii)
Substitute the value of x² from (ii) in (i);
9x² + 4 (y - 2)² = 36
9 × 2y + 4 (y - 2)² = 36
18y + 4 (y - 2)² = 36
9y + 2 (y - 2)² = 18
9y + 2 (y² + 4 - 2y) = 18
9y + 2y² + 8 - 4y = 18
2y² + 5y + 8 - 18 = 0
2y² + 5y - 10 = 0
y = - 5 ± √5² - 4×2×- 10 / 2×2
y = - 5 ± √ 25 + 80 / 2
y = - 5 ± √ 105 / 2
y = - 5 ± 10.24 / 2
y = - 5 + 10.24 / 2
y = 5.24/2
y = 2.62
y = - 5 - 10.24 / 2
y = - 15.24 / 2
y = - 7.62
From (ii);
x² = 2y
x² = 2 × 2.62
x² = 5.24
x = 2.28
x² = 2y
x² = 2 × - 7.62
x² = - 15.24
x = 3.9i
Thus, The solution of the expression are,
x = 2.28 , y = 2.62
Or, x = 3.9i , y = - 7.62

6(y + 6) = 3y - 33 solve
Answer:
y=-23
Let's solve your equation step-by-step:
6(y+6)=3y−33
Step 1: Simplify both sides of the equation
6(y+6)=3y−33
(6)(y)+(6)(6)=3y+−33(Distribute)
6y+36=3y+−33
6y+36=3y−33
Step 2: Subtract 3y from both sides
6y+36−3y=3y−33−3y
3y+36=−33
Step 3: Subtract 36 from both sides
3y+36−36=−33−36
3y=−69
Step 4: Divide both sides by 3.
3y/3=−69/3
y=−23
Answer:
y=−23
