2. Carissa also has a sink that is shaped like a half-sphere. The sink has a volume of 3617 in3. One day, her sink clogged. She has to use one of two conical cups to scoop the water out of the sink. The sink is completely full when Carissa begins scooping. (a) One cup has a diameter of 2 in. and a height of 4 in. How many cups of water must Carissa scoop out of the sink with this cup to empty it? Round the number of scoops to the nearest whole number. *** Complete sentences
Answer:Yes, your answers are correct.
The volume of a cone is given by V = 1/3πr²h. Since the diameter of the first cone is 4, the radius is 2; therefore the volume is
V = 1/3π(2²)(8) = 32π/3
We divide the volume of the sink, 2000π/3, by the volume of the cone:
2000π/3 ÷ 32π/3 = 2000π/3 × 3/32π = 6000π/96π = 62.5 ≈ 63.
The diameter of the second conical cup is 8, so the radius is 4. The volume then is:
V = 1/3π(4²)(8) = 128π/3
Dividing the volume of the sink, 2000π/3, by 128π/3:
2000π/3 ÷ 128π/3 = 2000π/3 × 3/128π = 6000π/384π = 15.625 ≈ 16

Solve for x in the figure below
Answer:
x = 20
Step-by-step explanation:
5x - 21 = 2x + 39 (corresponding angles are congruent)
Collect like terms
5x - 2x = 21 + 39
3x = 60
Divide both sides by 3
3x/3 = 60/3
x = 20

A regular octagon with sides of length 8 and an apothem of length 9.66 has
an area of ___ square units
Α. 73.66
Β. 77.28
C. 17.66
D. 309.12
Ε. 38.64
F. 618.24
Answer:
D. 309.12
Step-by-step explanation:
The computation of the area is shown below:
As we know that
Area = a4s
where
a denotes apothem
s denotes side
So, the area is
= 9.66 (4) (8)
= 9.66 (32)
= 309.12 square units

Based on the graph, the sales manager published a report in May 2020 claiming that so far in 2020, the group had met its goal of doubling sales.
Is this conclusion correct? Why or why not?
OA
Yes, the conclusion is correct because each of the 2020 sales bars is at least twice as high as the 2019 sales bars, showing that
the sales are at least doubled.
OB.
OC.
Yes, the conclusion is correct because the advertising campaign was designed to double sales.
No, the conclusion is not correct because the graph shows only the first four months of the year.
No, the conclusion is not correct because the y-axis does not begin at zero, so the relative size of the bars does not represent
the ratio of 2020 sales to 2019 sales.
OD.
No, the conclusion is not correct because the y-axis does not begin at zero, so the relative size of the bars does not represent the ratio of 2020 sales to 2019 sales.
What is a graph?
A graph can be described as a pictorial representation of data. A graph is made up of a y-axis and the x-axis. The y-axis must begin at zero.
Examining the given graph, the y-axis does not begin at zero. Also, the length of the bars in 2020 is not twice then length of the bars in 2019.

The point D(-3, 1) is reflected over the x-axis. What are the coordinates of the resulting point, D′?
Answer:
The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same.
Step-by-step explanation:
For example, when point P with coordinates (5,4) is reflecting across the X axis and mapped onto point P', the coordinates of P' are (5,-4).

Find general solutions of the differential equation. Primes denote derivatives with respect to x.
6xy^3+2y^4+(9x^2y^2+8xy^3) yâ²=0
Answer:
[tex]\mathbf{3x^2y^3+2xy^4=C}[/tex]
Step-by-step explanation:
From the differential equation given:
[tex]6xy^3 +2y ^4 +(9x^2y^2+8xy^3) y' = 0[/tex]
The equation above can be re-written as:
[tex]6xy^3 +2y^4 +(9x^2y^2+8xy^3)\dfrac{dy}{dx}=0[/tex]
[tex](6xy^3 +2y^4)dx +(9x^2y^2+8xy^3)dy=0[/tex]
Let assume that if function M(x,y) and N(x,y) are continuous and have continuous first-order partial derivatives.
Then;
M(x,y) dx + N (x,y)dy = 0; this is exact in R if and only if:
[tex]\dfrac{{\partial M }}{{\partial y }}= \dfrac{\partial N}{\partial x}}} \ \ \text{at each point of R}[/tex]
relating with equation M(x,y)dx + N(x,y) dy = 0
Then;
[tex]M(x,y) = 6xy^3 +2y^4\ and \ N(x,y) = 9x^2 y^2 +8xy^3[/tex]
So;
[tex]\dfrac{\partial M}{\partial y }= 18xy^3 +8y^3[/tex]
[tex]\dfrac{\partial N}{\partial y }[/tex]
Let's Integrate [tex]\dfrac{\partial F}{\partial x}= M(x,y)[/tex] with respect to x
Then;
[tex]F(x,y) = \int (6xy^3 +2y^4) \ dx[/tex]
[tex]F(x,y) = 3x^2 y^3 +2xy^4 +g(y)[/tex]
Now, we will have to differentiate the above equation with respect to y and set [tex]\dfrac{\partial F}{\partial x}= N(x,y)[/tex]; we have:
[tex]\dfrac{\partial F}{\partial y} = \dfrac{\partial}{\partial y } (3x^2y^3+2xy^4+g(y)) \\ \\ = 9x^2y^2 +8xy^3 +g'(y) \\ \\ 9x^2y^2 +8xy^3 +g'(y) =9x^2y^2 +8xy^3 \\ \\ g'(y) = 0 \\ \\ g(y) = C_1[/tex]
Hence, [tex]F(x,y) = 3x^2y^3 +2xy^4 +g(y) \\ \\ F(x,y) = 3x^2y^3 + 2xy^4 +C_1[/tex]
Finally; the general solution to the equation is:
[tex]\mathbf{3x^2y^3+2xy^4=C}[/tex]
If a certain factory produces 24 Pepsi bottles of one liter capacity each in 12 minutes,
approximately how many Pepsi bottles does it produce in one hour?
Answer:
It produces 120 bottles in one hour.
Step-by-step explanation:
This question can be solved by proportions.
24 Pepsi bottles of one liter capacity each in 12 minutes
24/12 = 2 bottles per minute.
How many Pepsi bottles does it produce in one hour?
One hour has 60 minutes. So
60*2 = 120
It produces 120 bottles in one hour.
