Step-by-step explanation:
The volume of a sphere is two-thirds the volume of a cylinder.
What is the volume of a cylinder that has the same diameter as a sphere with a volume of 14 u3, in u3?
Answer:
21u3
Step-by-step explanation:
Given that the volume of a sphere is two-thirds the volume of a cylinder.
Let the volume of the sphere be A and that of the cylinder be B then
A = 2/3 B
Given that the volume of the sphere of same diameter as a cylinder is 14u3 then
14u3 = 2/3 B
Multiply both sides by 3
42u3 =2B
Divided both sides by 2
21u3 = B
The volume of the cylinder in terms of u3 is 21u3

What is the equation of the line that passes through the point (4,11) and is perpendicular to the line with the following equation? Y=4/3x+7
Answer:
Step-by-step explanation:
y = (4/3)x+7
Slope of the line is 4/3.
Slope of any perpendicular to the line is -¾.
Point-slope equation for line of slope -¾ that passes through (4,11):
y-11 = -¾(x-4)
Of course, you may want to rearrange it to slope-intercept form or standard form.
y = -¾x+15 slope-intercept
x+4y = 60 standard

The projected sales volume of a video game cartridge is given by the function s(p) = 3000 / (2p + a), where s is the number of cartridges sold, in thousands; p is the price per cartridge, in dollars; and a is a constant. If according to the projections, 100000 cartridges are sold at 10 dollars per cartridge, how many cartridges will be sold at 20 dollars per cartridge?
Answer: 149 cartridges will be sold at 20 dollars per cartridge.
Step-by-step explanation:
Given: The projected sales volume of a video game cartridge is given by the function [tex]s(p)=\dfrac{3000}{2p+a}[/tex], where s is the number of cartridges sold, in thousands; p is the price per cartridge, in dollars; and a is a constant.
Put s(p)=100000, p= 10, we get
[tex]100000=\dfrac{3000}{2(10)+a}\\\\\Rightarrow\ 100=\dfrac{3}{20+a}\\\\\Rightarrow\ 100(20+a)=3\\\\\Rightarrow\ 2000+100a=3\\\\\Rightarrow\ 100a=-1997\\\\\Rightarrow\ a=-19.97[/tex]
i.e. [tex]s(p)=\dfrac{3000}{2p-19.97}[/tex]
Put p=20, we get
[tex]s(20)=\dfrac{3000}{2(20)-19.97}\\\\=\dfrac{3000}{40-19.97}\\\\=\dfrac{3000}{20.03}\approx149[/tex]
Hence, 149 cartridges will be sold at 20 dollars per cartridge.

WILL GIVE BRAINLY
Answer:
living in an environment with increased carbon dioxide levels.
Step-by-step explanation:
International Space Station have higher carbon dioxide levels as compared to the earth. The earth's atmosphere has now changed due to increased carbon emission by vehicles and factories. The environmental pollution has increased and the trees are being cut which has created an environment less of oxygen and more of carbon dioxide. Bacteria's find it easy to live on earth because of increase carbon dioxide levels.
Answer:
living in an environment with increased radiation levels and living in an environment with increased carbon dioxide levels.

Determine the magnitude of the force exerted on the block with mass 1.4 kg by the block with mass 6.4 kg.
Answer in units of N
9514 1404 393
Answer:
55 8/39 N ≈ 55 N
Step-by-step explanation:
The net force on the 1.4 kg block is proportional to its mass. That is, the ratio of net force on that block to the net force on the total mass is the same as the ratio of the block's mass to the total mass.
net force on 1.4 kg = (1.4 kg)/(1.4 +6.4 kg) × (64 N -15 N) = (7/39)(49 N)
net force on 1.4 kg = 8 31/39 N
Then the force applied by the 6.4 kg mass is ...
64 N - 8 31/39 N = 55 8/39 N ≈ 55 N . . . . applied by 6.4 kg mass
Convert the following unit volumes as indicated. Choose the right answer.
1,500 cm3 to quarts (liquid).
Answer:
15/10L (1.5)L
Step-by-step explanation:
on the picture
If it's helpful ❤❤❤
THANK YOU.
The unit conversion is solved and 1,500 cm³ = 1.584 quarts in volume.
Given data:
The initial volume is represented as 1,500 cm³.
To convert 1,500 cm³ to quarts (liquid), the conversion factor between these two units is determined as:
1 quart (liquid) is equal to approximately 946.35 cm³.
Therefore, calculate the conversion as follows:
1,500 cm³ * (1 quart / 946.35 cm³) = 1.584 quarts (approximately)
Hence, 1,500 cm³ is approximately equal to a volume of 1.584 quarts (liquid).

B. The lengths of the legs are cosθ and 1.
C. The lengths of the legs are cotθ and cosθ.
D. The lengths of the legs are sinθ and 1.
Answer:
A
Step-by-step explanation:
https://www.flickr.com/photos/dwread/12159826533/
The required length of legs of the triangle drawn in the unit circle is given as sinθ and cosθ. Option A is correct.
These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operations.
Here,
For the length of the legs,
Perpendicular length,
sinθ = x / 1 {hypotenuse of the triangle is the radius of the circle which 1 unit in measurement.}
Similarly,
cosθ = y / 1
Thus, the required length of legs of the triangle drawn in the unit circle is given as sinθ and cosθ. Option A is correct.

Find the solution of the system of equations.
6x – 3y = -30
3x – 6y = 12
Answer:
Step-by-step explanation:
6x – 3y = -30
3x – 6y = 12
Multiply the top equation by 2 and write the bottom equation under it.
12x - 6y = - 60
3x - 6y = 12 Subtract
9x = - 72 Divide by 9
x = - 72/9
x = - 8
6x - 3y = - 30
6*-8 - 3y = -30
-48 - 3y = - 30 Add 48 to both sides.
-3y = - 30 + 48
-3y = 18 Divide by -3
y = -18/-3
y = -6
Solve for x:
3x – 2(6 - x) = 7x + 2(5 + x) – 6
Answer:
-4
Step-by-step explanation:
3x-2(6-x)=7x+2(5+x)-6
First, distribute.
3x+ −12+ 2x = 7x + 10 + 2x −6
Combine like terms on each side.
5x − 12= 9x + 4
To solve for x, pick a side to solve. I will solve the right x.
5x - 12 = 9x + 4
-5x -5x
-12 = 4x + 4
Subtract 4 to isolate the variable.
-16 = 4x
Divide 4.
-4 = x
