1. Akari has a sink that is shaped like a half-sphere. The sink has a volume of
8000
*n in. One day, her sink clogged. She has to use one of two
3
cylindrical cups to scoop the water out of the sink. The sink is completely full,
when Akari begins scooping. Hint: you may need to find the volume for both.
(a) Cup A has a diameter of 4 in, and a height of 8 in. Find the Volume of Cup A.
(b) Determine how many cups of water must Akari scoop out of the sink with Cup A to
empty it? Round the number of scoops to the nearest whole number, and make
certain to show your work.
(c) Cup B has a diameter of 8 in, and a height of 8 in. Find the volume of Cup B.
(d) How many cups of water must she scoop out of the sink with Cup B to empty it?
Round the number of scoops to the nearest whole number, and make certain to
show your work
Answer:
the fisrst cup has a volume of 100.53

5.Regarding the equations below. What is the value of x?
5x + 2y = 4
x – 3y = –23
Answer:
x=−2
y=7
Step-by-step explanation:
5x+2y=4
x−3y=−23
In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.
5x+2y=4,x−3y=−23
To make 5x and x equal, multiply all terms on each side of the first equation by 1 and all terms on each side of the second by 5.
5x+2y=4,5x+5(−3)y=5(−23)
Simplify.
5x+2y=4,5x−15y=−115
Subtract 5x−15y=−115 from 5x+2y=4 by subtracting like terms on each side of the equal sign.
5x−5x+2y+15y=4+115
Add 5x to −5x. Terms 5x and −5x cancel out, leaving an equation with only one variable that can be solved.
2y+15y=4+115
Add 2y to 15y.
17y=4+115
Add 4 to 115.
17y=119
Divide both sides by 17.
y=7
Substitute 7 for y in x−3y=−23. Because the resulting equation contains only one variable, you can solve for x directly.
x−3×7=−23
Multiply −3 times 7.
x−21=−23
Add 21 to both sides of the equation.
x=−2
The system is now solved.
x=−2,y=7

An angle measures 62.4° less than the measure of its complementary angle. What is the
measure of each angle?
Answer:
28
Step-by-step explanation:
So if it's a complementary angle is equals 90 degrees total. So subtract 62 from 90. 90-62=28
1. what is the equation of a line that has an x-intercept of 2 and a y-intercept of 8
Answer:
B
Step-by-step explanation:
x- intercept = 2 .So, Coordinate(2 , 0)
y-intercept = 8 . So, Coordinate (0, 8)
[tex]Slope = \frac{8-0}{0-2}\\\\=\frac{8}{-2}\\\\=-4[/tex]
Slope y-intercept form: y = mx + b {Here, b is y-intercept}
y = -4x + 8

x2 - 2x - 3 = 0 What two numbers add to -2 and multiply to -3 ? → +1 and -3
So...we can factor it like this...
(x + 1)(x - 3) = 0 Set each factor equal to zero and solve for x.
x + 1 = 0 and x - 3 = 0
x = -1 and x = 3
Step-by-step explanation:
find the domain and range of f(x)= -2x²+3
Answer is in pictures and work as well
Answer:
you need to know what domain and range mean... so remember domain is the input.... range is the output.. :)
Step-by-step explanation:
the input .. "x" in this case.. can be any number .. so the domain is all real numbers.
the output.. or range.. is limited.. b/c the square on the 'x" will always make that number positive.. and then it's multiplied by the negative 2.... so that term will always be negative. : | hmmmm so when is that squred term the smallest it can be? hmmm when it's zero... soooo this function will .. at it's greatest point be 3 and go down from there...
the range is from -∞ to 3
see? :)

solve for a, geometry work
Answer:
a = 45 degrees
Step-by-step explanation:
Since both angles are a, they are equal to each other
Also, we know that the right angle means it measures 90 degrees
So, (180-90)/2 = a
a = 45 degrees

In each of the following graphs, the two given polygons are similar. Write precisely a single dilation (coordinates of center and coefficient) by which the image (labeled with primed letters) was obtained. Will Give Brainiest!!!!!
Answer:
Center: (0,0) coefficient: [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
The side of the smaller polygon is 1/3 the size of the larger one, and that is why the coefficient is 1/3.
Polygon MNPQ was dilated by a scale factor of 1/3 and center of dilation (0, 0) to create M'N'P'Q'.
What is dilation?Dilation is the increase or decrease in the size of a figure by a scale factor of k, thereby creating an image.
From the diagram:
Scale factor = N'P' / NP = 2/6 = 1/3
Center = (0, 0)
Polygon MNPQ was dilated by a scale factor of 1/3 and center of dilation (0, 0) to create M'N'P'Q'.
