The initial weight of the toy before removing the spare parts was found to be 440gm since the weight after 25% removal was given as 330gm

The final weight of the toy after removal of spare parts is given as 330g

Percentage weight removed in the form of spare parts from the toy= 25%

Let us consider the initial weight to be x

The equation becomes,

x – 0.25x = 330, since 25% is removed from the original weight of the toy to give us the final weight of 330gm

0.75x= 330

x = 330/0.75

x = (330*100)/75

x = 440

Therefore, initial weight of the toy was found to be 440g

A formula is used to find a Center of a circle with a (h, k) center and a radius of r has the equation:

[tex](x-h)^2 + (y-k)^2 = r^2[/tex]

A circle is a collection of all points in a plane that are uniformly distanced from a fixed point. The radius of a circle is the difference between the center and any point itself along the perimeter.

A circle is a closed curve that extends outward from a set point known as the center, with each point on the curve being equally spaced from the center. The equation for a circle with a (h, k) center and a radius of r is:

[tex](x-h)^2 + (y-k)^2 = r^2[/tex]

This is the equation's standard form. So, if we know the radius and center coordinates of a circle, we can rapidly determine its equation.

So, it would take 36 days for all 24 gallons of water to leak out of the pool at this rate

To find out how many days it takes for all 24 gallons of water to leak out of the pool, we need to determine the rate at which the water is leaking and use that to calculate the total time it takes for the pool to empty.

We know that the pool initially has 24 gallons of water and that it is leaking out at a rate of 2 gallons every 3 days. This means that the pool loses 2/3 of a gallon of water per day.

To find out how many days it will take for the pool to empty, we can divide the total amount of water in the pool by the rate at which it's leaking out.

24 gallons / (2/3 gallons/day) = 24*3/2 = 36 days

Therefore, it would take 36 days for all 24 gallons of water to leak out of the pool at this rate.

Answer:

correct answer is 72

Step-by-step explanation:

Each walkway is around 51 yards long.

Pythagoras Theorem is the way in which you can find the missing length of a right angled triangle.

The triangle has three sides, the hypotenuse (which is always the longest), Opposite (which doesn't touch the hypotenuse) and the adjacent (which is between the opposite and the hypotenuse).

Pythagoras is in the form of;

a²+b²=c²

However, it can also be written in the form of c²=a²+b²

In order to find the hypotenuse, you will have the length of two sides, for example, these could be 3 and 4.

As 'C' is always the hypotenuse, you have to work out the two other lengths, and you do this by squaring the numbers.

3²=9 and 4²=16.

As you're looking for C, you've got to add these together

9+16=25

As a²+b²=c², this means that the answer for C is the square root of 25.

√25= 5

Divide the square in half to make a right triangle. Now, use Pythagoras' theorem to solve for the hypotenuse.

a²+b²=c²

⇒ 36²+36²=c²

⇒ 1296+1296=c²

⇒ 2592=c²

∴ c =50.9116

Round to the nearest whole number, we get c = 51 yards.

Thus, each walkway is around 51 yards long.

All these antiderivatives are equivalent as they are different ways of solving the same problem and differ only by a constant value.

What is an antiderivative?

An antiderivative, also known as a primitive function or indefinite integral, is the reverse operation of taking a derivative. In other words, if the derivative of a function f(x) is g(x), then f(x) is said to be an antiderivative of g(x).

The antiderivative of sin(x)cos(x) can be found using the product-to-sum identities:

(sin(x)cos(x))' = (sin(x)cos(x))'
                      = (1/2)(cos(2x) - sin(2x)) + C

Another way to find the antiderivative of sin(x)cos(x) is to use the chain rule:
(sin(x)cos(x))' = (sin(x))'cos(x) + sin(x)(cos(x))'
                     = -sin(x)cos(x) + cos(x)sin(x) + C

A third way is to use integration by parts, where we take u = sin(x) and dv = cos(x)dx. This gives us:
(sin(x)cos(x))' = sin(x)cos(x) - ∫cos(x)sin(x)dx + C

Another way is to use the substitution method, where we set u = cos(x) and du = -sin(x)dx. This gives us:
(sin(x)cos(x))' = sin(x)cos(x) + ∫-sin(x)cos(x)du + C

Lastly, we can use the trigonometric identity method where we use sin(2x) = 2sin(x)cos(x) and integrate.
This gives us: (sin(x)cos(x))' = (1/2)sin(2x) + C

Hence, All these antiderivatives are equivalent as they are different ways of solving the same problem and differ only by a constant value.

Two rays may combine to form an angle in the plane in which they are positioned. Two planes colliding results in an angle as well. We refer to them as dihedral angles.

Here,

Assuming that A (0, -3), C (0, 5), and B are the triangle's vertices (6, 3)

Set point P to be (0, 0)

There is;

A' = 3/2 * (0,-3) = (0,-9/2) = (0,-4.5) (0,-4.5)

C' = 3/2 * (0,5) = (0, 15/2) = (0,7.5) (0,7.5)

B' = 3/2 * (6,6/3) = (9 , 9/2) = (9,4.5) (9,4.5)

Therefore, on a scale, the image of ABC is bigger than that of the image of A'B'C.

No , it is not possible to draw a triangle with the given side length of 4cm , 3cm , and 7cm as sum of two sides ( 4cm + 3cm ) is not greater than the third side ( 7cm).

As given in the question,

Measure of the required triangle are given as follow:

Measure of Side length 1 = 4cm

Measure of Side length 2= 3cm

Measure of Side length 3 = 7cm

To draw a triangle following condition need to be satisfied:

Sum of the measure of two side length is always greater than the measure of the third side length.

Here for a given triangle ,

4cm + 3cm

= 7cm

= measure of the side length 3

It does not satisfied the required property to draw a triangle.

Therefore, it is not possible to draw a triangle with given measurements as ( 4cm + 3cm ) is not greater than the third side.

Answer: 12

Step-by-step explanation:

For the equation to have infinitely many solutions, it must be an identity.

[tex]3(5+x)+kx+8=7(2x+3)+(x+2)\\\\15+3x+kx+8=14x+21+x+2\\\\x(k+3)+23=15x+23\\\\\implies k+3=15 \implies k=12[/tex]
