The astronaut is experiencing approximately 6.21 g's in the centrifuge.

a. To find the angular velocity of the centrifuge in radians per second, we first need to convert the number of revolutions per minute to revolutions per second. Since there are 60 seconds in a minute, the angular velocity (ω) can be calculated as follows:

Angular velocity (ω) = (Number of revolutions per minute) / 60

Given that the centrifuge makes 72 complete revolutions in 2 minutes:

ω = 72 / 2 / 60 = 1.2 revolutions per second

Next, to find the distance an astronaut travels around the center each second, we can use the formula for the circumference of a circle:

Circumference = π × diameter

Circumference = π × 70 feet

Circumference ≈ 220 feet

Distance traveled each second = Circumference × ω

Distance traveled each second = 220 feet × 1.2 revolutions per second ≈ 264 feet

So, the angular velocity of the centrifuge is approximately 1.2 radians per second, and an astronaut travels around the center approximately 264 feet each second.

b. The acceleration (a) of an object moving in circular motion with a constant velocity (v) and a radius (r) is given by the formula:

[tex]a = v^2 / r[/tex]

Since the astronaut is moving at a constant velocity around the center of the centrifuge, we can use the same formula to find their acceleration. The velocity of the astronaut is the distance traveled each second (264 feet) and the radius of the centrifuge is half of its diameter (70 feet / 2 = 35 feet):

Acceleration (a) = (264 feet per second)^2 / 35 feet ≈ 198.86 feet per second squared

So, the astronaut's acceleration is approximately 198.86 feet per second squared.

c. To find how many g's the astronaut is experiencing in the centrifuge, we need to compare their acceleration with the acceleration due to gravity on Earth (32 feet per second squared). One g is equivalent to the acceleration due to gravity.

Number of g's = Acceleration (astronaut) / Acceleration due to gravity on Earth

Number of g's = 198.86 feet per second squared / 32 feet per second squared ≈ 6.21 g's

So, the astronaut is experiencing approximately 6.21 g's in the centrifuge.

Answer:

10u+t=18+10t+u

(If this doesn't match one of the equations, please post your options so I can put it in the form of one of your options.)

Step-by-step explanation:

Let there be a number [tu] where t is the tens and u is ones digit.

t+u=16.

Now we reverse the number [ut] is 8 more than [tu].

[ut]=18+[tu]

So [ut]=10u+t because u is the tens  and t is the ones digit

and [tu]=10t+u because t is the tens and u is the ones digit.

The equation you are looking for is

10u+t=18+10t+u.

Let's solve it just for fun:

Subtract u on both sids:

9u+t=18+10t

Subtract 10t on both sides:

9u-9t=18

Divide both sides by 9:

u-t=2

The system is:

u-t=2

u+t=16

--------------add!

2u  =18

u=9

If u=9 and u+t=16, then t=7.

To the original number is 79.

The new number is 97 (is this 18 more than the other; yep).

Answer:

-3

Step-by-step explanation:

If a line is perpendicular to another the product of their slope should equal -1. The slope of the first equation is -1 and -1*1=-1 so the slope of the second equation is 1. That means that the equation looks like y=x+b. We know that when x is 4 y is 1. So plugging in those values you get 1=4+b, subtracting 4 you get -3=b. So the y-intercept is -3

The height of the triangle is approximately [tex]4.35\text{ mm}[/tex]

Step-by-step explanation:

The area of a triangle can be calculated by using the Heron's formula.

Heron's formula:  

Suppose a triangle has sides [tex]a'[/tex], [tex]b'[/tex] and [tex]c'[/tex], then the semi-perimeter [tex]S[/tex] of the triangle is represented by the expression,

[tex]S=\frac{a'+b'+c'}{2}[/tex]

The area [tex]A[/tex] of the traingle is formulated below.

[tex]\fbox {\begin\\A=\sqrt{s(s-a')(s-b')(s-c')}\end{minispace}}[/tex]

To calculate the area of the triangle with sides [tex]9 \text{ mm}[/tex] , [tex]6 \text{ mm}[/tex] and [tex]12 \text{ mm}[/tex], first find the semi-perimeter.

[tex]S=\frac{9+6+12}{2}\\S=\frac{27}{2}\\S=13.5 \text{ mm}[/tex]

Now, the area of the triangle is calculated below.

[tex]A=\sqrt{s(s-a)(s-b)(s-c)}\\A=\sqrt{13.5(13.5-9)(13.5-6)(13.5-12)}\\A=\sqrt{13.5 \times 4.5 \times 7.5 \times 1.5}\\A=\sqrt{\frac{135}{10}\times\frac{45}{10}\times\frac{75}{10}\times\frac{15}{10}} \\A=\sqrt{\frac{(15\times3\times3) \times (15\times3) \times (15\times5) \times15}{100\times100}}\\A=\frac{15\times15\times3\sqrt{15 } }{100} \\A=2.25\times3\times3.87\\A=26.122[/tex]

Area A of a triangle with a altitude P and one side as base B on which the altitude P is drawn, can be calculated as,

[tex]\fbox{\begin\\A= \left[\frac{1}{2}(B)(P)\right]\\\end{minispace}}[/tex]

Now, the area of the same triangle can also be calculated as,

[tex]A=\frac{1}{2}(12)(x)\\A=6x[/tex]

In the above calculations, area of the triangle is calculated in two ways.

Therefore, both the areas can be equated to obtain the altitude [tex]x[/tex].

[tex]6x=26.122\\x=\frac{26.122}{6}\\x=4.35[/tex]

Thus, the height of the triangle is evaluated as [tex]\fbox{4.35 \text{ mm}}[/tex].

Points to remember

Volume of hemisphere = (2/3)πr³

Where 'r' is the radius

To find the volume of large hemisphere

Here radius = 13 in

Volume V₁ =  (2/3)πr³

 = (2/3) * 3.14 * 13³

 = 4599.33 cubic inches

To find the volume of small hemisphere

Here radius = 13 - 3 = 10 in

Volume V₂ =  (2/3)πr³

 = (2/3) * 3.14 * 10³

 =2093.33 cubic inches

To find the volume of sink

Volume = V₂ - V₁

Answer:

Area of the triangle is 25.9 feet²

Step-by-step explanation:

* Lets explain how to solve the problem

- In Δ ABC

∵ m∠ B = 9° 20' = 9 + 20/60 = (28/3)°

∵ b = 2.92 feet

- b is the side opposite to angle B

∵ m∠ C = 80° 40' = 80 + 40/60 = (242/3)°

- Lets find c the side opposite to angle C by sing the sine rule

∵ [tex]\frac{b}{sinB}=\frac{c}{sinC}[/tex]

∴ [tex]\frac{2.92}{sin(28/3)}=\frac{c}{sin(242/3)}[/tex]

- By using cross multiplication

∴ [tex]c=\frac{2.92(sin(242/3)}{sin(28/3)}=17.77[/tex]

- The area of the triangle = 1/2 (b)(c)sin∠A

∵ The sum of the interior angles of a triangle is 180°

∴ m∠ A + m∠ B + m∠ C = 180°

∵ m∠ B = (28/3)°

∵ m∠ C = (242/3)°

∴ m∠ A + 28/3 + 242/3 = 180

∴ m∠ A + 90° = 180° ⇒ subtract 90 from both sides

∴ m∠ A = 90°

∴ Area of the triangle = 1/2 (2.92)(17.77) sin(90)

∵ sin(90) = 1

∴ Area of the triangle = 1/2 (2.92)(17.77) = 25.9 feet²

* Area of the triangle is 25.9 feet²

Final answer:

To solve the equations using substitution, isolate y from the first equation, substitute it into the second, solve for x, and then use the value of x to find y. The solution to the system is x = -1 and y = -5.

Explanation:

To solve the system of equations by substitution, we will first isolate y in one of the equations and then substitute it into the other equation.

Step 1: Isolate y in the first equation.

We have y = 3x - 2. This equation is already solved for y, so we can use it as our substitution.

Step 2: Substitute y into the second equation.

Our second equation is x - y = 4. We substitute y with 3x - 2 to get x - (3x - 2) = 4.

Step 3: Solve for x.

Now, we simplify and solve for x:

x - 3x + 2 = 4

-2x + 2 = 4

-2x = 4 - 2

-2x = 2

x = -1

Step 4: Substitute x back into the first equation to solve for y.

Using x = -1 in the first equation y = 3x - 2, we get:

y = 3(-1) - 2

y = -3 - 2

y = -5

Therefore, the solution to the system of equations is x = -1 and y = -5.

Final answer:

The measure of the other angle that is complementary to a 13º angle is 77º.

Explanation:

If two angles are complementary, it means they add up to 90 degrees. In this case, one angle is given as 13º. To find the measure of the other angle, we subtract the given angle from 90º because complementary angles sum up to 90 degrees.

So, if we let x represent the measure of the other angle, the equation becomes:

13° + x = 90°

To find x, we subtract 13 from both sides:

The calculation would be:

90º - 13º = 77º.

Therefore, the measure of the other angle is 77º.

Hence, the correct answer is:

The perimeter of a rectangle is P=2L+2W where L is the length and W is the width.

We have that P=10, so 10=2L+2W.

10=2L+2W

10=2(L+W)  By factoring using the distributive property.

2(5)=2(L+W)  I factored 10 as 2(5).

If 2(5)=2(L+W), then 5=L+W.

Whole numbers are {0,1,2,3,4,5,6,7,8,9,10,...}. They are your counting numbers and 0.

I think they want natural numbers {1,2,3,4,...}.  This is also just called the counting numbers. The reason I think they want this because if one of the dimensions is 0, we won't actually have a rectangle.

So now looking for numbers from this set that satisfy: L+W=5.

Answer: $212.5

Step-by-step explanation:

250% = 2.5

So we multiply 85.00 by 2.5

85*2.5=212.5

So it is $212.5

Answer:

D. More Than 1 Solution

Step-by-step explanation:

Let the system of equations be:

[tex]a_1x+b_1y=c_1...(1)[/tex]

[tex]a_2x+b_2y=c_2...(2)[/tex]

If the graph of equation (1) and (2) are the same, then the two graphs coincide with each other.

What that means is that; the two graphs intersects at infinitely many points.

Therefore the system must have infinitely many solutions.

In other words the system has more than one solution.

NB: At least one solution means exactly one solution and/or more than one solution. But lines that coincide cannot have exactly one solution.

Answer:

1 triangle is possible

Step-by-step explanation:

If there are two sides and a non included angle is given then there could be 0,1 or 2 triangles depend on the measure of the given angle and the lengths of the given sides.

We will discuss some conditions which will clarify that how many triangles are there in the given condition.

CASE 1: If A is obtuse and a>b then there is 1 triangle.

CASE 2: If A is obtuse and a<b then there is 0 triangle.

CASE 3:  If A is acute and a>b then there is 1 triangle.

CASE 4:  If A is acute  and h<a<b then there are 2  triangles possible.

CASE 5: If A is acute  and a=h then there is 1 right angle triangle.

CASE 6: If A is acute and a<h then there are 0 triangles possible.

Therefore according to the given condition A= 6° which is acute and a>b, So this condition matches the CASE 3:

According to this there is 1 triangle possible....
