The term "if and only if" makes the sentence bi-conditional. A triangle is equilateral if and only if it has three congruent sides.

A conditional statement with its opposite expressed in the form of "if and only if," collectively known as a bi-conditional statement. Bi-conditional logic is the theory behind bi-conditional assertions.

This can be compared to the conditional sentence, "if this, then that." Due to the lack of a "if and only if," it is not bi-conditional. The reversal of a conditional statement's ability to produce a bi-conditional depends on whether it is also true.

6.6 is the correct number

Step-by-step explanation:

The base is 2.2 inches. The height is 3 inches. So the area is 2.2 × 3 = 6.6 square inches.

Answer: 13

Step-by-step explanation:

As the sum of the angles of a triangle is 180, we have that 39 + 90 + 3x+12 = 180.

3x = 180 - 39 - 90 - 12

3x = 39

The required value of the function is 2

In the case of a function from one set to the other, each element of X receives exactly one element of Y.

The given function is of the form :

g(x) = - x² - 7

Now let us find the required values.

g (-3) = - (-3)² - 7 = 2

g (-2) = - (-2)² - 7 = -3

g (1 ) = - ( -1 )² - 7 = -6

Hence the required value of the function is 2 at x = -3 .

The total number of orders that Angela has to clean are 60.

Given:

Number of pairs of shoes cleaned by Angela = 12

Let the total number of shoes to be cleaned be x.

So,12 pairs of shoes are 20% of her total orders.

20% of x = 12

(20/100)x = 12

0.2x = 12

x = 12/ 0.2

x = 60

Therefore, Angela has to clean a total of 60 pairs of shoes.

Factoring polynomials is the inverse process of multiplying polynomials. After factoring a polynomial, if we divide the polynomial with the factors then the remainder will be zero.

In linear equation, $ 442.54 tall is the tower.

What are a definition and an example of a linear equation?

Suppose A is the window, B is the top of the tower, C is the bottom of the tower, and D is the point on the tower at the same horizontal level as the window.

Find BD, DC then add these together to give this°.

For BD :  AD is 350 ft, the angle CAD is 42.  

So BD/350 = tan 42°.  

      BD =  0.9004 × 350

      BD  = 315.14

   AD/350  =  tan20°

    AD =   0.364 × 350

Answer: 1/4

Step-by-step explanation:

The scale factor is the same as the ratio of the length of a side of the image to the length of the corresponding side in the preimage.

We know that A'D'=2 and AD=8, so the scale factor is 2/8 = 1/4.

The conversion of 5 kiiometers to miles is 3.11 miles

The given parameters are

Distance covered by the students = 5 kilometers

The ratio of the distance is given as

1 mile : 1.61 kilometers

Multiply both sides of the ratio by 5

So, we have the following ratio expression

5 * 1 mile : 1.61 kilometers * 5

Evaluate the product in the above expression

So, we have the following ratio expression

5 miles : 8.05 kilometers

Divide both sides of the ratio by 1.61

So, we have the following ratio expression

5/1.61 miles : 8.05/1.61 kilometers

Evaluate the quotient in the above expression

So, we have the following ratio expression

3.11 miles : 5 kilometers

Rewrite as

5 kilometers : 3.11 miles

This means that

5 kilometers = 3.11 miles

Substitute 5 kilometers = 3.11 miles  in Distance covered by the students = 5 kilometers

So, we have

Distance covered by the students = 3.11 miles

Hence, the distance covered by the students is 3.11 miles

Finding the numeric value of the regression line, it is found that the electric bill in a month with temperature of 48 degrees is of $157.59.

To find the numeric value of a function, we replace each instance of the variable in the function by the desired value.

In the context of this problem, the function is given as follows:

y = 227.19 - 1.45x.

Which y giving the electric bill for a month of temperature x degrees.

The temperature is of 48 degrees, hence to find the electric bill, the lone instance of x in the function is replaced by 48, hence:

y = 227.19 - 1.45(48) = $157.59.

Hence the electric bill in a month with temperature of 48 degrees is of $157.59.

The number of rectangular containers will be necessary to package 6,400 candles is 143

The number of cylindrical containers will be necessary to package 6,400 candles is 157.

The container that would minimise cost is the rectangular container because it would $67 less to use the rectangular container.

The first step is to determine the total cost of packing 6400 candles using the rectangular container.

Total cost = number of containers needed x cost of one rectangular container

Number of containers needed = total number of candles to be packages / number of candles the container can hold

6400 / 45 = 142.22 = 143 rectangular containers

Total cost = $16 x 143 = $2,288

The next step is to determine the total cost of packing 6400 candles using the cylindrical container.

Total cost = number of containers needed x cost of one cylindrical container

Number of containers needed = total number of candles to be packages / number of candles the container can hold

6400 / 41 = 156.1  = 157 cylindrical containers

Total cost = $15 x 157 = $2,355

Difference in costs = $2,355 - $2,288 = $67
