Sphere B is the image of sphere A after dilation by a scale factor of 44. If the volume of sphere A is 50 m^3
3
, find the volume of sphere B, the image.
Step-by-step explanation:
there is no image here. and we don't know, if B is smaller or lager than A.
anyway, the volume of a sphere is
4/3 × pi × r³ = 4/3 × pi × r×r×r
that means the scale factor applying to r (radius) has to be multiplied in 3 times (with every r). so, to compare the volumes, the volume scale factor is cubed the linear scale factor.
44³ = 85184
if B is smaller, then its volume is 50/85184 m³
if B is larger, then its volume is 50×85184 m³
since this a such a big number, you made possibly a typo with the scale factor.
The volume of sphere B, the image of sphere A after dilation by a scale
factor of 44, is approximately 1,223,762.42 cubic meters.
What is mean by Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
Since, The volume of a sphere is given by the formula:
V = (4/3) pi r
where V is the volume, pi is the constant 3.14.., and r is the radius of the sphere.
Since, sphere A has a volume of 50 cubic meters, we can use this formula to solve for its radius:
50 = (4/3) pi r
r = (3/4) (50 / pi)
r = (3/(4pi) 50)^(1/3)
r = 2.67 meters
Note that we know,
The radius of sphere A, we can use the scale factor of 44 to find the radius of sphere B:
rₐ = 44 rₓ
rₐ = 44 × 2.67
rₐ = 117.48 meters
Finally, we can use the volume formula again to find the volume of sphere B:
V(B) = (4/3) pi rₓ
V (B) = (4/3) pi (117.48)
V (B) = 1,223,762.42 cubic meters
Therefore, the volume of sphere B, the image of sphere A after dilation by a scale factor of 44, is approximately 1,223,762.42 cubic meters.

Step-by-step explanation:
Answer:
its c
Step-by-step explanation:
Mariana buys bottles of orange juice at the corner store. assume each bottle of juice is the same price. the proportional relationship between the number of juice bottles bought, j, and the total cost in dollars and cents, c, can be represented by the equation c=0.8jc=0.8j. what is the cost in dollars and cents of each bottle of juice?
By evaluating the function in j = 1, we conclude that each bottle costs 80 cents.
What is the cost in dollars and cents of each bottle of juice?We know that the total cost in dollars can be represented by the linear equation:
C(j) = 0.8*j
Where C is the cost, and j is the number of juice bottles bought.
Then to get the cost of each bottle, we can evaluate the function in 1, which means buying only one.
C(1) = 0.8*1 = 0.8
So each bottle costs $0.80 (or 80 cents).

Find the volume of this irregular figure.
Hint: Find the volume of the whole rectangular prism, then subtract the volume of the missing piece, which is also a rectangular prism.
Answer:
470 cm³
Step-by-step explanation:
Volume of rectangular prism = width × length × height
⇒ Volume of whole rectangular prism = 9 cm × 10 cm × 8 cm
= 720 cm³
Side lengths of the missing piece:
width = 5 cmlength = 10 cmheight = 8 cm - 3 cm = 5 cm⇒ Volume of the missing piece = 5 cm × 10 cm × 5 cm
= 250 cm³
⇒ Volume of irregular figure = 720 cm³ - 250 cm³
= 470 cm³

What transformation will prove that these two triangles are CONGRUENT.
Answer:
Reflection across the x axis
Step-by-step explanation:
When the triangle reflects across the x axis it will directly map over the other triangle and will appear to be congruent
Answer:
A reflection over the x - axis.
Step-by-step explanation:
The new position of a point, a line, a line segment, or a figure after a transformation is called its image. line y=x. A reflection is a type of transformation known as a flip. The figure will not change size or shape. Mathematical reflections are shown using lines or figures on a coordinate plane. The reason these two triangles are congruent is they reflect each other meaning that they are complete opposites reflecting. When mapped, they are completely reflecting.
Shenika factored the polynomial completely. what is the value of a? 5x3 35x2 6x 42 (5x2 a)(x b) 1 5 6 7
Factorising the polynomial 5x³ + 35x² + 6x + 42, the value of A is 6.
Factorisation of polynomialFactorising a polynomial simply means to decompose the polynomial into a product of two or more polynomials.
Therefore, let's factorise 5x³ + 35x² + 6x + 42 and find the value of A
(5x² + A)(x + B)
Therefore,
5x³ + 35x² + 6x + 42

What is the volume of the following rectangular prism and the top of the shape 9 units squared and the hight is 3 2/3
Answer:
2x^3 + 5x^2 - 18x - 45 m
V = lwh
V = (x + 3)(x - 3)(2x + 5)
V = ((x)(x) + (x)(-3) + (3)(x) + (3)(-3))(2x + 5)
V = (x^2 - 3x + 3x - 9)(2x + 5)
V = (x^2 - 9)(2x + 5)
V = (x^2)(2x) + (x^2)(5) + (-9)(2x) + (-9)(5)
V = 2x^3 + 5x^2 - 18x - 45
A car with a cost price of $5200 is
sold at a profit of 15%. Calculate the
selling price
Answer:
We are given the initial price of a car and we are also told that the car sold for a 15% profit which means that the price that the car was sold for is 15% more than it's initial price. This is just a simple multiplication problem which we multiply the initial price by the total percentage plus 0.15
[tex]Sold\ Price = Initial\ Price *(Total\ Percentage+Profit\ Percentage)[/tex]
[tex]Sold\ Price = \$5200*(1+0.15)[/tex]
[tex]Sold\ Price = \$5200*(1.15)[/tex]
[tex]Sold\ Price = \$5980[/tex]
Therefore, our final answer is that the selling price was $5980

Trapezoid defg is dilated according to the rule do,4(x,y) to form the image trapezoid d'e'f'g', which is shown on the graph. on a coordinate plane, trapezoid d prime e prime f prime g prime has points (negative 8, 8), (negative 3, 8), (negative 5, 4), and (negative 8, 4). what are the coordinates of point g of the pre-image? (-2, 1) (-4, 2) (-12, 0) (-32, 16)
Since the figure is dilated by a factor of 4, the coordinates of point g of the pre-image is (-2, 1)
How to determine the coordinates of point g?The coordinates of the image are given as:
d' = (-8,8)e' = (-3,8)f' = (-5,4)g' = (-8,4)The dilation rule is given as:
(x,y) -> 4(x,y)
So, we have:
(-8,4) = 4 * g
Divide both sides by 4
g = (-2,1)
Hence, the coordinates of point g of the pre-image is (-2, 1)
