Kristy asks Lonnie to think of a number add it with 3 to it multiply the sum by 2 and the subtract 6. let (n) stand for Lonnies starting number. which expression represents Lonnies final number
Answer:
2(n + 3) - 6 is the expression that represents the final number.
Step-by-step explanation:
Answer: the expression becomes 2(x +3) - 6.
Let the number be x. Then according to the question,
Step 1 :- Adding 3
=> x + 3
Step 2 :- Multiply the sum by 2
=> 2×(x + 3)
Step 3 :- Subtract 6
=> 2(x +3) - 6
Thus the expression becomes 2(x +3) - 6.

Item 3 Find the distance from the point (-2,6) to the line y=x-8 . Round your answer to the nearest tenth
Answer:
16 units
Step-by-step explanation:
The distance of the point P ( -2 , 6 ) to the line y = x - 8 is given by the equation D = 8√2 units = 11.3 units
What is the distance from the point to a line?The shortest distance between any two points on an infinite straight line is called the distance from a point to a line. The length of the line segment connecting the point to the closest point on the line is the perpendicular distance between the point and the line.
Let the equation of line be = Ax + By + C = 0
Let the point be P ( x₀ , y₀ )
Distance of a point to line D = | Ax₀ + By₀ + C | / √ ( A² + B² )
Given data ,
Let the distance be represented as D
Now , let the point be P = P ( -2 , 6 )
Let the equation of line be A
The value of A is
y = x - 8
Subtracting y on both sides of the equation , we get
x - y - 8 = 0 be equation (1)
Now , Distance from a point to line D = | Ax₀ + By₀ + C | / √ ( A² + B² )
Substituting the values in the equation , we get
Distance from a point to line D = | 1 ( -2 ) + ( -1 ) ( 6 ) - 8 | / √ ( 1² + 1² )
On simplifying the equation , we get
Distance from a point to line D = | -2 - 6 - 8 | / √2
Distance from a point to line D = | -16 | / √2
Distance from a point to line D = 16/√2
Multiply the numerator and denominator of the fraction by √2 , we get
Distance from a point to line D = 16√2 / 2
Distance from a point to line D = 8√2 units
Hence , the distance is 8√2 units = 11.3 units

b. 1/2(x+y)
c. x+y/2
The expression 1/2(x + y) is representing one-half the sum of x and y option (b) 1/2(x+y) is correct.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
It is given that:
“One-half the sum of x and y”
Here x and y are the real numbers.
A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.
The sum of the x and y is (x + y)
The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
One-half the sum of x and y = 1/2(x + y)
Thus, the expression 1/2(x + y) is representing one-half the sum of x and y option (b) 1/2(x+y) is correct.

A boy wants to jump onto a carousel that is spinning at a rate of 14 revolutions per minute. If the carousel is 23 feet in diamter, how fast must the boy run to match the speed of the carousel and jump on?A) 2.68 feet per second.B) 1,011.59 feet per second.C) 33.72 feet per second.D) 16.86 feet per second.
Answer:
16.86 ft/s
Step-by-step explanation:
Given that
Speed of the carousel, s = 14 rpm
Distance from the carousel, d = 23 ft
To start with, we convert the given speed to revolution per second, so that
s = 14/60 rev/sec
To find the needed speed, we use the formula
v =2πnR, remember that Diameter = 2R, so we substitute D for 2R and get πnD
v = πnD, and we use this to find our needed velocity
v = 3.142 * 14/60 * 23
v = 72.266 * 14/60
v = 16.86 ft/s
Therefore the boy must run at a speed of 16.86 ft/s in order to be able to match the carousel and jump on it

Ganesh is making a scale model of the Space Needle in Seattle, Washington. The space needle is 605 feet tall. If the model is 1/100 the actual size of the Space Needle, how tall is the model? _____ feet
Answer:
[tex]Model = 6.05ft[/tex]
Step-by-step explanation:
Given
[tex]Space\ Needle = 605ft[/tex]
[tex]Scale\ Model = \frac{1}{100}[/tex]
Required
Determine the height of the model.
To do this, we simply multiply the scale model by the height of the space needle.
[tex]Model = Scale\ Model * Space\ Needle[/tex]
[tex]Model = \frac{1}{100} * 605ft[/tex]
[tex]Model = \frac{605ft}{100}[/tex]
[tex]Model = 6.05ft[/tex]
Hence, the height of the model is 6.05ft
