Answer:
The volume of the tumor experimented a decrease of 54.34 percent.
Step-by-step explanation:
Let suppose that tumor has an spherical geometry, whose volume ([tex]V[/tex]) is calculated by:
[tex]V = \frac{4\pi}{3}\cdot R^{3}[/tex]
Where [tex]R[/tex] is the radius of the tumor.
The percentage decrease in the volume of the tumor ([tex]\%V[/tex]) is expressed by:
[tex]\%V = \frac{\Delta V}{V_{o}} \times 100\,\%[/tex]
Where:
[tex]\Delta V[/tex] - Absolute decrease in the volume of the tumor.
[tex]V_{o}[/tex] - Initial volume of the tumor.
The absolute decrease in the volume of the tumor is:
[tex]\Delta V = V_{o}-V_{f}[/tex]
[tex]\Delta V = \frac{4\pi}{3}\cdot (R_{f}^{3}-R_{o}^{3})[/tex]
The percentage decrease is finally simplified:
[tex]\%V = \left[1-\left(\frac{R_{f}}{R_{o}}\right)^{3} \right]\times 100\,\%[/tex]
Given that [tex]R_{o} = R[/tex] and [tex]R_{f} = 0.77\cdot R[/tex], the percentage decrease in the volume of tumor is:
[tex]\%V = \left[1-\left(\frac{0.77\cdot R}{R}\right)^{3} \right]\times 100\,\%[/tex]
[tex]\%V = 54.34\,\%[/tex]
The volume of the tumor experimented a decrease of 54.34 percent.
Represent this statement as an equation: The difference of twice a number and 3 is 11.
Answer:
2x - 3 = 11
Step-by-step explanation:
"difference" means subtraction, so it is subtraction.
"twice a number" simply means 2x, since you do not know what the specified number is, it is x. and the 2 and just making it twice the number.
"Is 11" just means equals 11.
so, 2x - 3 = 11.
hope this helps!
Is 400 A whole number a integer a real number or rational number
Answer:
400 is a rational number because it can be expressed as the quotient of two intergers 400 divided by 1
Step-by-step explanation:
the square root of 400 is rational because the product is 20 which is a whole number making it a rational number because a rational number is any interger, fraction , terminating decimal, or repeating decimal.
Does anyone know how to do any of these problems? My notes are no help and none of my classmates know what to do either.
Answer:
17) 40°
18) 3x+22
19) (1,-4.5)
20) (-1,-2.5)
Step-by-step explanation:
17) 99=59=40°
18) 2x+7+x+15=3x+22
19) 6-(-8)=14
14/2=7
-8+7=1
-2-(-7)=5
5/2=2.5
-2-2.5=-4.5
midpoint = (1,-4.5)
20) 6-(-8)=14
14/2=7
-8+7=-1
5-(-10)=15
15/2=7.5
-10+7.5=-2.5
Midpoint = (-1,-2.5)

Step-by-step explanation:
solve for h 7a=10-2h
Step-by-step explanation:
7a = 10 - 2h
2h = 10 - 7a
h = (10 - 7a)/2
express the set in interval notation:
15 - 2(3 - 2x) = 46
Answer:
[tex]9.25[/tex]
Step-by-step explanation:
So we have the equation:
[tex]15-2(3-2x)=46[/tex]
First, distribute the -2:
[tex]15-2(3)-2(-2x)=46[/tex]
Multiply:
[tex]15-6+4x=46[/tex]
Subtract:
[tex]9+4x=46[/tex]
Subtract 9 from both sides:
[tex]4x=37[/tex]
Divide both sides by 4:
[tex]x=37/4=9.25[/tex]
And we're done!

2. Sketch the graph: 4y – 3x = 12.
Answer:
see below
Step-by-step explanation:
A graphing calculator is useful for this.
__
To find the x-intercept, set y=0 and solve for x:
0 -3x = 12
x = -4 . . . . . . divide by -3
To find the y-intercept, set x=0 and solve for y:
4y - 0 = 12
y = 3 . . . . . . divide by 4
Plot the x- and y-intercepts on their respective axes and draw a line through them.

What is the missing statement for step 6?
Answer: c
Step-by-step explanation:
An object is translated by (x-2, y-6). If one point in the pre-image has the coordinates (-3, 7,) what would be the coordinates of this image
Answer:
(- 5, 1 )
Step-by-step explanation:
Given the translation rule
(x, y ) → (x - 2, y - 6 )
This means subtract 2 from the original x- coordinate and subtract 6 from the original y- coordinate, that is
(- 3, 7 ) → (- 3 - 2, 7 - 6 ) → (- 5, 1 )
Solve: - (g+ 12) = 5(9 - 12)
Answer:
-27
Step-by-step explanation:
(g+ 12) = 5(9 - 12)
g = 45 - 60 - 12
g = - 27
Answer:
g = 3
Step-by-step explanation:
- (g+ 12) = 5(9 - 12) (remove parentheses by distributive property. See attached for reference)
g(-1) + 12(-1) = 9(5) -12(5)
-g - 12 = 45 - 60
-g - 12 = -15 (add 12 to both sides)
-g = -15 + 12
-g = -3 (multiply both sides by -1)
g = 3
10v-3v=35 what is the answer to this.
answer is v=5
Step-by-step explanation:
10v-3v=7v
7v=35
v=35/7
v=5
Answer: [tex]v=5[/tex]
Simplify both sides of the equation
[tex]10v+-3v=35[/tex]
[tex](10v+-3v)=35[/tex] (Combine Like Terms)
[tex]7v=35[/tex]
Divide both sides by 7
[tex]7v/7=35/7\\v=5[/tex]

Step-by-step explanation:
(-64=)-8+6=-2+(-16=)-4-3=5
Answer:
50Step-by-step explanation:
(6 + √-64) (3 - √-16)
= (6 + 8i) (3 - √-16)
= (6 + 8i) (3 - 4i)
= (6 * 3 - 8 (-4)) + (6(-4) + 8 * 3)i
= 6 * 3 - 8(-4) = 50
= 6(-4) + 8*3 = 0
= 50 + 0i
= 50
the length of segment HJ if H lies at (-1,7) and J lies at (8,-5)
Answer:
HJ = 15Step-by-step explanation:
To get the length of segment HJ if H lies at (-1,7) and J lies at (8,-5), we will use the formula for calculating the distance between two points as shown;
D = √(x₂-x₁)²+(y₂-y₁)²
From the coordinates x₁ = -1, y₁ = 7, x₂ = 8, y₂ = -5
HJ = √(8-(-1))²+(-5-7)²
HJ = √(8+1)²+(-12)²
HJ = √81+144
HJ = √225
HJ = 15
Hence the length of segment HJ is 15 units
