Explanation:
The number 1 is spelled as "one", which clearly has an "e" in it. This contradicts the original statement that we don't need this letter.
The other numbers of 6 (six), 2 (two), and 4 (four) don't involve "e"s at all. So they can be ruled out.

Name the property of real numbers illustrated by the equation. 2(s-t) = 2 s-2 t
The Distributive property of real numbers is illustrated by the equation 2(s-t) = 2 s-2 t.
Distributive property of real number is denoted by x(y+z)=x*y+x*z , which means "x" will be multiplied with each term present inside the bracket.
For Example :
3(4+1) =3*4+3*1
=12+3
=15
In the given question
LHS = 2(s-t)
On applying Distributive property we get ,
=2*s-2*t
=2s-2t = RHS
Hence distributive property is applied here.
Therefore , the property of real numbers that is illustrated by the equation 2(s-t) = 2 s-2 t is Distributive property .

Step-by-step explanation:
that is just to be read from the chart.
a)
we see Kiev has 1° C.
Oslo has 2° C.
what is the difference ? 2 - 1 = 1°
b)
don't get confused.
the chart says temperatures at midday.
6 hours later IS 6pm.
the temperature in Kiev raises during that time from 1° up by 6°.
that means the temperature there is then 1 + 6 = 7° C at 6 pm.
Answer:
a. 9 °C
b. 7°C
Step-by-step explanation:
a. Difference, Rome and Oslo
→Rome: 11°C
→Oslo: 2°C
11°C- 2°C = 9°C
b. Kiev
The chart shows temperatures at midday (12pm). After 6 hours it's 6 pm.
→Kiev 1°C
→Temperature will rise 6°C
1°C + 6 °C = 7°C
At 6pm, the temperature in Kiev will be 7°C.

whats the formula for speed distance and time?
We know the formulae:
[tex]\text{Speed} = \dfrac{\text{Distance}}{\text{Time}}[/tex]
Let us solve an example to understand the concept better.
Example:Question: Find the speed of a car which travelled 12 km in 2 hours.
Solution: We know the following
Car travelled (Distance): 12 kmTime travelled: 2 hoursSubstitute the information provided into the speed formula:
[tex]\implies \text{Speed} = \dfrac{\text{Distance}}{\text{Time}}[/tex]
[tex]\implies \text{Speed} = \dfrac{\text{12 km}}{\text{2 hours}} = \boxed{6 \ \text{km/hour}}[/tex]
Therefore, the speed of the car is 6 kilometers per hour.
Concept #2: Distance FormulaeFrom the previous concept, we had:
[tex]\text{Speed} = \dfrac{\text{Distance}}{\text{Time}}[/tex]
Finding the distance formula through step-by step work:
Let Speed = S, Distance = D, and Time = T.
[tex]\implies \text{S} = \dfrac{\text{D}}{\text{T}}[/tex]
Multiply "t" on both sides:
[tex]\implies \text{S} \times \text{T}= \dfrac{\text{D}}{\text{T}} \times \text{T}[/tex]
[tex]\implies \text{S} \times \text{T}={\text{D}[/tex]
From the above work, we can say that Distance = Speed × Time.
Let us solve an example to understand the concept better.
Example:Question: A train travelled from point A at a speed of 16 km/h in 2 hours to reach point B. Find the distance (Point A - Point B) travelled by the train.
Solution: We know the following
Speed of train: 16 km/hTime taken to travel from A to B: 2 hoursSubstitute the information provided into the distance formula:
[tex]\implies \text{Distance = Speed} \times \text{Time}[/tex]
[tex]\implies \text{Distance = 16 km/h} \times \text{2 hours}[/tex]
⇒ Distance = 16 km × 2 = 32 km
Therefore, the train travelled 32 km to reach point B.
Concept #3: Time FormulaeFrom the previous concept, we had:
[tex]\text{Distance = Speed} \times \text{Time}[/tex]
Finding the time formula through step-by step work:
Let distance = D, speed = S, and time = T
[tex]\implies \text{D = S} \times \text{T}[/tex]
Dividing "S" both sides:
[tex]\implies \dfrac{\text{D}}{\text{S}} = \dfrac{\text{S} \times \text{T}}{\text{S}}[/tex]
[tex]\implies \dfrac{\text{D}}{\text{S}} = \text{T}[/tex]
From the above work, we can say that Distance/Speed = Time.
Let us solve an example to understand the concept better.
Example:Question: A plane traveled 200 km at a speed of 100 km/h. How much time did it take to travel 200 km?
Solution: We know the following
Distance travelled by the plane: 200 kmSpeed of plane: 100 km/hSubstitute the information provided into the time formula:
[tex]\implies \text{Time} = \dfrac{\text{Distance}}{\text{Speed}}[/tex]
[tex]\implies \text{Time} = \dfrac{\text{200 km}}{\text{100 km/h}} = \dfrac{\text{2 km}}{\text{1 km/h}} = \boxed{\text{2 hours}}[/tex]
Therefore, it took 2 hours to travel 200 km at a speed of 100 km/h.

What is the nth term rule for this
sequence
The nth term of the given quadratic sequence begins 8, 11, 16, 23, 32, = n² + 7.
What is quadratic sequence?Quadratic sequences are those that contain a word. They are distinguished by the fact that the first differences between terms really aren't equal, but really the second differences between terms remain equal.
What is a quadratic sequence's rule?The difference between each term inside a quadratic series is not equal, but the second difference between every term is equal.
How can you tell whether a sequence is straight or quadratic?A linear sequence is a number pattern that increases or lowers by the same amount each time. The common difference is the amount by which it increases or drops. Quadratic sequence: The difference between every term increases or decreases at a steady rate in quadratic sequence.
According to the given data:Given:
8, 11, 16, 23, 32,
The nth rule is:
n² = 1² , 2², 3², 4² , 5²
n² = 1 , 4 , 9 , 16 , 25
Subtracting the equation:
8 , 11 , 16 , 23, 32
1 , 4, 9 , 16 , 25
we get:

Determine whether the given measures define 0,1,2 , or infinitely many triangles. Justify your answers.
a=25, b=21, m
We can form an endless number of triangles when you are given two sides and no measurement of angle i.e a = 25 , b = 21
For Example -
We can chose the value of angle from 0-360 degrees with side length a = 25 and b =21, how many different triangles are possible to create?
Create one of the triangles with a protractor having the side lengths a = 25 m and b = 21 m and angle 12° and third side can be adjusted to your preferred length. You have built a triangle.
Similarly by changing the length of the third side and measure of the angle we will get an entirely new triangle.
It's important to notice that you choose the side lengths and angle. This suggests that you might make a different decision. By employing the same angles, you were able to make an infinite number of different triangles.
Therefore, with simply the measurements of one angle and a side length, we can create an endless number of triangles.

A bicycle has tires with a diameter of 26 inches. Find the radius and circumference of a tire. Round to the nearest hundredth, if necessary.
A circle is a curve sketched out by a point moving in a plane. The radius and the circumference of the circle are 13 inches and 81.6814 inches, respectively.
What is a circle?A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the center.
Given that diameter of the circle is 26 inches. Therefore, the radius and the circumference of the circle can be written as,
Diameter of circle = 2 × (Radius of the circle)
Radius of the circle= Diameter of circle / 2
Radius of the circle = 26 inches / 2
Radius of the circle = 13 inches
Circumference of circle = 2 × π × (Radius of the circle)
= 2 × π × 13 inches
= 26π inches
= 81.6814 inches
Hence, the radius and the circumference of the circle are 13 inches and 81.6814 inches, respectively.
