The cat's weight in grams will be 1450 grams.

According to the question,

We have the following information:

A cat weighs 82 ounces. There are about 28.3 grams in 1.6 ounces.

Now, we can easily find the weight of the cat in grams by following the given steps:

1.6 ounces = 28.3 grams

We will find the weight in grams in 1 ounce using division.

1 ounce = 28.3/1.6 grams

Now, the weight of 82 ounces in grams:

82 ounces = (28.3*82)/1.6 grams

82 ounces = 1450.375 grams

After rounding it off to the nearest whole gram, we have 1450 grams.

Hence, the cat's weight in grams will be 1450 grams.

You could also do 0.20 x 0.50 to get 0.10

For this combination can be used , the answer would be  639450 ways

What is combination?

In arithmetic, a combination may be a choice of things from a group that has distinct members, such the order of choice doesn't matter.

Main body:

Given, the total number of members in the chorus are 30.

Also, it is given that 6 members from the chorus have to be

chosen for a special performance.

The number of ways of choosing r people out of given n people

is given by the expression

nCr

= n!/r!(n-r)!

So the number of ways of choosing 6 members out of 30 are

³⁰C₆

=  30!/24!6!

= 639450 ways

But since only the expression to represent the number of ways

was asked not the exact number of ways we can leave the

answer as ³⁰C₆ .

Hence total number of ways is 639450 ways.

Answer:

12 y 42

Step-by-step explanation:

Let x and y represent the two numbers:

(1)  x+y=54 and (2)  x-y=30

Solve for x:

x-y=30

x=30-y

Substitute into equation (1):

2y=24

y=12

Substitute into equation (2):

x-12=30

The width of the canyon, from the point on the north rim of the canyon which is 7,224 feet above sea level to the point on the south rim, which is 5,091 feet above sea level, found using the trigonometric ratios is about 4,790.8 feet

The trigonometric ratios indicate the relationship between the interior angles of a right triangle and two sides of the triangle.

The specified angle of depression from the point 7,224 feet above the sea level on the north rim of the of the canyon to the point 5,091 feet above sea level on the south rim, θ = 24°

The difference in height between the north rim and the south rim = 7,224 feet - 5,091 feet = 2,133 feet

The width of the canyon can therefore be found using trigonometric ratios for tangent of an angle as follows;

In a right triangle, we get;

[tex]tan(\theta) = \dfrac{Opposite \, side \, to \, angle \, \theta}{Adjacent \, side \, to \, angle \, \theta}[/tex]

With regards to the the canyon, and the angle, θ, therefore;

[tex]tan(\theta) = \dfrac{Difference \ in \ height}{Width\ of \ the \ canyon }[/tex]

Plugging in the known values indicates;

[tex]tan(24^{\circ}) = \dfrac{2,133}{Width\ of \ the \ canyon }[/tex]

for the following gear train, tooth numbers are n2 = 12, n3 = 16, and n4 = 12 the speed of the arm is 426.67 rev/min.

The angular velocity of an item as it rotates around an axis or centre is quantified as the speed of rotation. Usually, it is expressed in terms of degrees,   per minute (RPM). The angular velocity of an object is a measure of how rapidly the object rotates around a central point and is connected to the linear velocity of the object around the perimeter of its path of revolution. In physics, the idea of It is used to explain the motion of things ranging from tiny particles to large celestial bodies, and it is an important aspect in understanding object behaviour. for the following gear train, tooth numbers are n2 = 12, n3 = 16, and n4 = 12

How to solve?

n1/n2 = n3/n4. In this case, the gear ratio for the first set of gears (gears 1 and 2) is 12/12 = 1. For the second set of gears (gears 3 and 4), the gear ratio is 16/12 = 4/3.

Since internal gear 5 is fixed, it must have the same number of teeth as gear 1, which is 12. Therefore, the number of teeth on internal gear 5 is 12.

To determine the speed of the arm, we need to use the equation for speed of rotation: speed of rotation = (speed of input shaft) x (gear ratio of gears 3 and 4) = 320 rev/min x (4/3) = 426.67 rev/min.

Therefore, the speed of the arm is 426.67 rev/min.

Both the number of frozen dinners and the number of can soups that were purchased total 10.

When a, b, and c are all real values and the coefficients of x and y, i.e., a and b, are not equal to zero, the equation is said to be linear in two variables. A few more examples of two-variable linear equations are 10x+4y = 3 and -x+5y = 2.

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) component are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

Let's say that "x" cans of soup and "y" frozen meals were purchased.

We may create the equations based on the above conditions,

x + y = 15 ————(I) (I)

200x + 500y = 4500 ——-(II) (II)

Now, y = 15 - x from (I).

If you change the value of "y" in equation (II), you obtain

200x + 500(15 - x) = 4500

200x + 7500 - 500x = 4500

300x = 3000

x = 3000/300

x = 10

In equation (I), x = 10 results in

y = 5

The result is that 10 cans of soup and 10 frozen dinners were bought.

The statement is false. It is always necessary for an agent to disclose the identity of the principal to any third person with whom he is contracting; else the contract becomes void.

Given that,

Any third party with whom an agent enters into a contract must always be informed of the identity of the principal; otherwise, the contract is null and void.

By speaking to the third party or carrying out an approved act, the principle reveals his or her identify and existence.

If the principle's identity is unknown and the third party has learned enough details to guess it, the principal is deemed to have been disclosed. The principal is in this case responsible to the third party; the agent is not. Contracts or other agreements between agents and third parties are regarded as agreements between the main and the third party.

Despite the fact that the agent is not a party to the contract, in the event that the principal breaches it, the agent is not personally liable for any damages that follow from the breach.

c) length of diagonal is 13 cm

We have given that

length (l) is decreasing at the rate of 2 cm/min

and the width (w) is increasing at the rate of

2cm/min,

⇒ dl/dt = −2 cm/min and dw/dt = 2cm/sse

Thus the perimeter (P) of a rectangle is,

P=2(l+w) ---(1)

differentiating above equation with respect to time (t) we get,

dp/dt = 2(dl/dt + dw/dt )

=> dp/dt = 2( -2 + 2 ) = 0

=> P = constant

Hence, there is no change in perimeter of rectangle.

(b)Now, it is given that length (l) is decreasing at the rate of 2 cm/min

and the width (w) is increasing at the rate of 2 cm/min,

Thus the area (A) of a rectangle is, A= l× w

=> dA/dt = l ×dw/dt + w×dl/dt (used differentaion

we have l = 12 cm and w = 5 cm

=> dA/dt = 12 (2) + 5(-2)

=> dA/dt = 24 - 10 = 14

Hence, the area is increasing at the rate of

14 cm²/min.

c) length of diagonal = √(12)² + (5)² = √144+25
