Step-by-step explanation:

x = first number  

x+1 = second number

x *  (x+1) = 272

x^2  +x  = 272

x^2 + x - 272 = 0     Use Quadratic Formula to find:

x=   16    x+1 = 17          OR       x =   -17     x+1 = -16

The smallest of the three integers is, 42

Option D is true.

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities.

Given that;

Three positive integers are in a ratio of 3 : 4 : 7 and have a sum of 196.

Hence, All the integers are,

⇒ 3x, 4x , 7x

Here, The sum is 196.

Hence, We can formulate;

⇒ 3x + 4x + 7x = 196

⇒ 14x = 196

⇒ x = 14

Thus, The smallest integers is,

⇒ 3x = 3 × 14

         = 42

Answer:

1/4

Step-by-step explanation:

You cannot subtract (or add) a fraction with different denominators so first, you need to find a common denominator. You can do this by finding the least common multiple (LCM).

Here the denominators are 2 and 4 so the LCM is 4.

After you find the LCM you need to multiply the denominator by a number that equals the LCM. Then multiply the numerator by that same number.

So convert both 1/2 and 1/4

1/4 x 1/1 = 1/4

1/2 x 2/2 = 2/4

Now we can just subtract the numerator from each other.

2/4 - 1/4 = 1/4

We cannot simplify the difference any more so keep it the same.

Answer:

Therefore, the factor pairs needed to answer 3z^2 + 26z - 9 are (-3, 9) and (3z - 1, z + 9).

Step-by-step explanation:

To factor the quadratic expression 3z^2 + 26z - 9, we need to find two numbers that multiply to give us 3 times -9 = -27, and add up to 26.

One way to do this is to list all the factor pairs of -27 and look for the pair that has a sum of 26:

-27 and 1

-9 and 3

-3 and 9

-1 and 27

We can see that the pair that adds up to 26 is -3 and 9. So we can use these numbers to write the quadratic expression as a product of two binomials:

3z^2 + 26z - 9 = (3z - 1)(z + 9)

Therefore, the factor pairs needed to answer 3z^2 + 26z - 9 are (-3, 9) and (3z - 1, z + 9).

To find out how much black cord the design needs, we must find the perimeter of the figures. In this case, it would be: 107.42ft

To find the perimeter of four-sided figures, we just have to add the length of their sides as shown below:

To find the area of the triangle we must add its sides, in this case it is a triangle that has all the sides equal so it would be like this:

2ft + 2ft + 2ft = 6ft

Finally, the perimeter of the circle is calculated by multiplying 2 * number pi * radius. So the operation would look like this:

2*3.14*1.5=9.42ft

Now all that remains is to add all the sides and we will know how much black cord we need

9.42ft + 24ft + 28ft + 52ft = 107.42ft

Additionally, the area of the figures is calculated as follows:

Rectangle:

To find the area shown for each figure, simply subtract the area of the superimposed figure as shown below:

The perimeter of a regular decagon with sides 5√6 is 50√6 ( option A)

A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference. Calculating the perimeter has several practical applications.

The perimeter of a shape is obtained by adding all the sides together.

Therefore, if one side is 5√6 inches, a decagon which is of 10sides will have 5√6 inches at all it's sides because it is a regular polygon.

Therefore P= 5√6 × 10

P = 50√6 inches.

therefore the perimeter of the decagon is 50√6 inches

Step-by-step explanation: the angles add the up 180°

The height of 165 cm is equivalent to 1.65 meters or 5 feet 5 inches.

This is a measurement of length or distance that is commonly used to describe the height of a person or object.

To convert centimeters to meters, you can simply divide the number of centimeters by 100. In this case, 165 cm divided by 100 gives you 1.65 meters.

To convert centimeters to feet and inches, you can first divide the number of centimeters by 2.54 to get the number of inches. Then, you can divide the number of inches by 12 to get the number of feet and the remainder will be the number of inches.

In this case, 165 cm divided by 2.54 gives you 64.96 inches. Dividing 64.96 inches by 12 gives you 5 feet with a remainder of 4.96 inches, which can be rounded to 5 inches.

So, the height of 165 cm is equivalent to 1.65 meters or 5 feet 5 inches.

Answer:

To approximate the solution to the system of equations, we need to find the point where the two lines intersect. From the second equation, we know that y = (1/2)x + 1. Substituting this expression for y into the first equation gives:

3x + 2[(1/2)x + 1] = -4

Simplifying and solving for x, we get:

3x + x + 2 = -4

4x = -6

x = -1.5

Substituting this value of x back into the second equation gives:

y = (1/2)(-1.5) + 1 = 0.25

Therefore, the solution to the system of equations is approximately (-1.5, 0.25).

So the answer is (−1.5, 0.25).

If you spin the spinner 75 times, the expected number of 2's is 15.

Since the spinner has 5 spots ranging from 1-5, the probability of getting a 2 on any given spin is 1/5.

Therefore, if you spin the spinner 75 times, the expected number of 2's is: (1/5) * 75 = 15

So, if you spin the spinner 75 times, you can expect to get 15 2's.

Probability itself has a number from 0 to 1.

The probability value is 0 (zero) for an event that is impossible or unlikely to occur, for example, cows laying eggs.

In the given situation, the required value of x for the given pair of adjacent angles is 30°.

When two angles have a similar vertex and side, they are referred to as neighboring angles.

The vertex of an angle is the point at which the rays that make up its sides come to an end.

When adjacent angles have the same vertex and side, they can be a complimentary angle or supplemental angle.

The definition of adjacent is next to or nearby.

Two next-door residences are an illustration of proximity.

Typically, we think of those who live on our street as neighbors.

So, we have:

x + x + 30 = 90

Now, solve for x as follows:

x + x + 30 = 90

2x + 30 = 90

2x = 90 - 30

2x = 60

x = 60/2

x = 30

Answer:

Proportional relationship between two quantities x and y means that the quotient y/x stays constant, i.e. that there is a constant c such that y=cx. In our case we have that y=3x+5 which means that x and y are NOT proportional.

Answer:

Check the explanation provided

Step-by-step explanation:

This equation does not represent a proportional relationship because it's graph does not pass through the origin (i.e. 0,0)

[tex]y = mx + c[/tex]

where m =  gradient OR slope

               = 3

           c  = y-intercept

               = 5

For the equation to have a proportional relationship, the value of c MUST BE '0’

The solution is given below.

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

here, we have,

Consider that on a coordinate plane-xy, the x-values increase from left to right, and y-values increase from bottom to up.

Given that the linear graph passes through (1,1).

It is given that the graph goes 3 units up for every 2 units right. This can also be understood as the graph goes 3 units down for every 2 units left.

From the point (1,1), the x-value corresponding to 2 units left is given by,

x=1-2

x= -1

Similarly, from the point (1,1), the y-value corresponding to 3 units down is given by,

y = 1 - 3

y= -2

So the point (-1,-2) must also lie on the same linear graph.

Therefore, option (b) is the correct choice.
