The given statement is True.

The term "corollary" refers to an outcome that follows logically from another action. You could claim that your rediscovered passion of reading is a corollary to the recent opening of a bookstore in your area. The term corollary describes the result of an action, such as the need to study more as a corollary to receiving a poor grade.

A theorem states that two angles that add up to 180° and form a straight line are regarded as "supplementary."

A corollary of this is known as the "Vertical Angle Theorem," which asserts that where two lines intersect, their angles across from each other are equal (in the diagram, a=c and b=d).

The theorem can be used to readily show the corollary because, according to its statement, it considerably depends on it. Consequently, the assertion is accurate.

After solving the question using Pythagoras' theorem we get, The ladder moving down the wall at 8 feet per second.

According to the question,  

The bottom(base) of the ladder is 12 feet,

the height of the ladder is 13 feet.

Now, We have to find the top of the ladder moving down the wall

by using Pythagoras' theorem,

hypotenuse ^2 = base^2 + perpendicular ^2

13^2 = x^2 + y^2

169 =  x^2 + y^2

After using Pythagoras' theorem

we have this equation and now we will differentiate both sides:  

0  =2x*dx/dt + 2y*dy/dt    

0  =24*1 + 3* dy/dt  

dy/dt = - 8 feet per second  

Positive whole number we have to take.

Step-by-step explanation:

f(x} = 3x + 1

g(x} = 2x -- 3

f(g(x)) = 3x + 1. (Calm down right?)

Let the x in the expression be (2x -- 3)

N.B x = g{x}

f(g(x)) = 3(2x --3} + 1

Open bracket

f(g(x)) = 6x -- 9 + 1

f(g(x)) = 6x -- 8...

2... Solve for g(f(x)), using the same strategy

g(f(x)) = 2x -- 3

x = f(x)

g(f(x)) = 2(3x + 1) -- 3

g(f(x)) = 6x + 2 -- 3

g(f(x)) = 6x -- 1

The expression when a = 2 and x = -4, given 2a-x. The value will be 8.

In mathematics, an operation is a function that transforms zero or more arguments or operands into a clearly defined output value. The number of operands in the operation determines how difficult it is.

Unary operations (i.e., operations of arity 1), which include additive inverse and multiplicative inverse, as well as binary operations (i.e., operations of arity 2), which include addition and multiplication, are the operations that are most frequently studied. The nullary operation, also referred to as a zero-arity operation, is a constant. The mixed product is an example of a ternary operation, also referred to as an operation of arity 3.

The arity is typically assumed to be limited. Even yet, infinitary operations are occasionally taken into account, in which case the "typical" operations of finite dimensionality are referred to as finiteary operations.

Similar to an operation, but with partial function in place of a function, is the definition of a partial operation.

Since, a= 2 and x= -4, then,

Answer:

Number of balls of clay: 10

Step-by-step explanation:

The volume of the cube is  [tex]$V_{\text{cube}}=7^3=343,$[/tex]

and the volume of a clay ball is: [tex]$V_{\text{ball}}=\frac43\cdot\pi\cdot2^3=\frac{32}{3}\pi.$[/tex]

Since the balls can be reshaped but not compressed, the maximum number of balls that can completely fit inside a cube is

[tex]\[\left\lfloor\frac{V_{\text{cube}}}{V_{\text{ball}}}\right\rfloor=\left\lfloor\frac{343}{\frac{32\pi}{3} }\right\rfloor.\][/tex]

Approximating with [tex]$\pi\approx3.14[/tex]

We have:

[tex]\[\left\lfloor\frac{V_{\text{cube}}}{V_{\text{ball}}}\right\rfloor=10.23565228[/tex]

We simplify to get:

[tex]\[\left\lfloor\frac{V_{\text{cube}}}{V_{\text{ball}}}\right\rfloor\approx10[/tex]

So:

Answer:    she gets 540

Step-by-step explanation:

   She earns 540 dollars since the saleswoman only gets 9% of it and she sold $6000 dollars worth of merchandise you divide by percentage

 Example:  1. Find the percentage of the original or real number. In this case, it's 500.

2. Multiply the final number by 100. 500 x 100 = 50,000.

3. Divide the result of the multiplication by the percentage. 50,000 divided by 40% = 1,250. Thus, 500 is 40% of 1,250.

When the second number in the ordered pair, b, is not equal to 0, the ratio is expressed as a/b.

An equation in which two ratios are made equal is known as a percentage.

As an illustration, you could express the ratio as 1: 3 if there is 1 guy and 3 girls.

Given,

Dog eats 2 cups in a day

There are 24 cups in each bag

Solution:

Dog eats one bag of food in  24 cups/2 cups = 12 days

One food bag is sufficient to feed the dog for 12 days

For 35 days, the number of food bags needed is

1/x = 12/35 where x be the number of food bags needed for the dog.

Using the properties of an arithmetic sequence we can conclude that the total number of match boxes is 66.

There is a consistent distinction between the words in a sequence of numbers known as a "arithmetic progression" or "arithmetic sequence" (AP).

We know that the bottom row of the pyramid has 11 matchboxes .

As we can see in the figure that the each succeeding step has one matchbox less.

Therefore the number of matchboxes in each row is in an AP.

Therefore the AP has a common difference of  -1 and the first term is 11

The last term of the AP is 1.

Therefore

aₙ = a + (n-1)d

or, 1 = 11 + (n-1)(-1)

or, n = 11

We know that the sum of all terms of an AP is given by

S=n/2{2a+(n-1)d}

or, S = 11/2 {2×11 + (10)(-1)}

or, S = 66

Therefore from the arithmetic progression we calculate that the total number of match boxes is 66.
