Answer:
V = 268 cubic inches
Step-by-step explanation:
[tex]V = \frac{4}{3} \pi r^{3}[/tex]
[tex]V = \frac{4}{3} \pi (4^{3} )[/tex]
[tex]V =\frac{4}{3}\pi (64)[/tex]
V = 268.0825731
V = 268
The volume of the sphere with radius 4 inches is V = 268.08 inches³
What is a Sphere?A sphere is symmetrical, round in shape. It is a three dimensional solid, that has all its surface points at equal distances from the center. It has surface area and volume based on its radius. It does not have any faces, corners or edges.
The Surface Area of a Sphere = 4πr²
The Volume of a Sphere = ( 4/3 ) πr³
where r is the radius of the sphere
Given data ,
Let the radius of the sphere be r = 4 inches
Let the volume of the sphere be V
So , Volume of a Sphere = ( 4/3 ) πr³
Substituting the given value of the radius, r = 4 in, we get:
V = (4/3)π(4³)
V = (4/3)π(64)
V = 268.08 inches³
Hence , the equation that finds the volume of the sphere is
V = (4/3)πr³ = (4/3)π(4³) = 268.08 inches³

Step-by-step explanation:
The question is asking what coefficient a could possibly be. By comparing the blue and red parabolas, it can be observed that the red parabola has been flipped and vertically stretched. Let's break this down.
First, in order for the red parabola to mirror the blue parabola, it needs the opposite sign. The blue parabola's coefficient is positive. In order to mirror this, the red parabola's coefficient will need to be negative.
Lastly, the red parabola has been stretched. In order for the red parabola to stretch, its coefficient has to be greater than 1.
In conclusion, the red parabola needs to be negative and have a value greater than 1. Therefore, the answer is a < -1.

Noah and James are each paid $15 per hour. However, this week Noah received a $60 bonus. Given that N and J represent the number of hours worked by Noah (N) and James (J), which expression can be used to represent their combined earnings for the week?
Answer:
15N+15J+60
Step-by-step explanation:
We know that Noah and James each receive $15 per hour. That means that to get the money one of them earned in a week, we multiply the money they earn ($15) by the hours they worked (N or J):
15 × N is what Noah earned.
15 × J is what James earned.
Combining those are just 15N + 15J. Then, we add the bonus Noah received ($60) to get their total combined earnings:
15N+15J+60
Answer:
15N+15J+60

Answer:
first, simplify the equation, 5x-8x is -3x. So 6-7x = -3x+10
now subtract 6 from both sides, -7x = -3x+4
now add 3x on both sides. -4x = 4. now divide 4/-4 is -1. Thus X=-1
Answer:
x=-1
Step-by-step explanation:
6 - 7x = 5x - 8x + 10
First move the variables (x) to one side:
6 - 7x = 5x - 8x + 10
+7x +7x
6 = 5x - 8x + 7x + 10
Subtract 10 from both sides:
6 = 5x - 8x + 7x + 10
-10 -10
-4 = 5x - 8x + 7x
Simplify:
4x = -4
Divide by 4 to isolate x:
4x = -4
÷4 ÷4
x=-1

Hello I need help At a certain temperature, the speed of sound in the air is 330 meters per second.
Which of the following expressions would convert this speed into kilometers per second?
Answer:
Firstly, we are told that the value we are supposed to convert is "330 meters per second." When we see the word "per," we know that the unit should be divided.
So, really, the value is:
[tex]330\ \frac{meters}{second}[/tex]
Which can be abbreviated to:
[tex]\frac{330\ m}{1\ sec}[/tex]
We can scratch off the last two answers because they involve an x, and that is not our given value.
We can also eliminate the second answer because we are supposed to convert to kilometers, which is abbreviated by "km."
So, the answer is A or:
[tex](\frac{330\ m}{1\ sec})(\frac{1\ km}{1000\ m})[/tex]
The equivalent expression is [tex](a)\ \frac{330m}{sec} \times \frac{1\ km}{1000\ m}[/tex]
SpeedSpeed is the rate of change of distance over time
The speed in meter per second is given as:
[tex]Speed =330m/sec[/tex]
Equivalent expressionTo convert from meters to kilometers, we simply multiply the distance by 0.001.
So, we have:
[tex]Speed =\frac{330m}{sec} \times 0.001[/tex]
Express 0.001 as 1/1000
[tex]Speed =\frac{330m}{sec} \times \frac{1}{1000}[/tex]
Rewrite as:
[tex]Speed =\frac{330m}{sec} \times \frac{1\ km}{1000\ m}[/tex]
Hence, the equivalent expression is [tex](a)\ \frac{330m}{sec} \times \frac{1\ km}{1000\ m}[/tex]

jenny is going to rent a truck for one day. There are two companies she can choose from, and they have the following prices. Company A charges $94 and allows unlimited mileage. Company B has an initial fee of $55 and charges an additional $0.60 for every mile driven. For what mileages will Company A charge less than Company B
Answer:
until 64 miles company A will charge less than company B, they will charge the same price at 65 miles then company B will charge more.
explanation:
94 = 55 + 0.6m
m = (94-55) / 0.6 = 65
The Company A charge less than Company B when the mileage will be more than 65 .
What is equation?
An equation is a mathematical statement that is made up of two expressions connected by an equal sign. For example, 3x – 5 = 16 is an equation.
According to the question
Jenny is going to rent a truck for one day.
Company A :
Charges $94 and allows unlimited mileage.
i.e
Rent of truck for one day = $94
Company B :
Has an initial fee of $55 and charges an additional $0.60 for every mile driven.
Let mile be m
i.e
Rent of truck for one day = $55 + $0.60m
Now, Company A charge less than Company B for mileages
For that we will first find equal point by making both Company's rent equal
Company's A Rent of truck for one day = Company's B Rent of truck for one day
The equation will be :
[tex]94 = 55 + 0.60m[/tex]
[tex]39 = 0.6m[/tex]
m = 65
So, at 65 miles both company will rent same but after 65 miles Company B will charge more than Company A .
Hence, The Company A charge less than Company B when the mileage will be more than 65 .

Answer:
49
Step-by-step explanation:
<EDA + <ADC = 180 (half an angle)
So:
180 - 61 = 119 = <ADC
The interior angles of the quadrilateral add up to 360- we already know three of them, so:
73 + 119 + 119 + C = 180 ->
311 + C = 180 ->
C = 180 - 311 ->
C = 49

A road running north to south crosses a road going east to west at the point P. Car A is driving north along the first road, and an airplane is flying east above the second road. At a particular time the car is 15 kilometers to the north of P and traveling at 60 km/hr, while the airplane is flying at speed 185 km/hr 10 kilometers east of P at an altitude of 2 km. How fast is the distance between the car and the airplane changing?
Answer:
D^2 = (x^2 + y^2) + z^2
and taking derivative of each term with respect to t or time, therefore:
2*D*dD/dt = 2*x*dx/dt + 2*y*dy/dt + 0 (since z is constant)
divide by 2 on both sides,
D*dD/dt = x*dx/dt + y*dy/dt
Need to solve for D at t =0, x (at t = 0) = 10 km, y (at t = 0) = 15 km
at t =0,
D^2 = c^2 + z^2 = (x^2 + y^2) + z^2 = 10^2 + 15^2 + 2^2 = 100 + 225 + 4 = 329
D = sqrt(329)
Therefore solving for dD/dt, which is the distance rate between the car and plane at t = 0
dD/dt = (x*dx/dt + y*dy/dt)/D = (10*190 + 15*60)/sqrt(329) = (1900 + 900)/sqrt(329)
= 2800/sqrt(329) = 154.4 km/hr
154.4 km/hr
