What is arithmetic operation?A subfield of mathematics known as arithmetic operations deals with the study and application of numbers to all other subfields of mathematics. Operations like addition, subtraction, multiplication, and division make up the bulk of it.
These fundamental mathematical operations (+, -, ×, and ÷) that we use every day.
Given age of Ken = 6 years
let age of Micah be m and age of Richard be r
acc. to condition
Micah is twice as old as Richard
m = 2r
Richard is three times as old as Ken
r = 3 ken
r = 3 x 6
r = 18
Richard age is 18 years.
m =2r
m = 2 x 18
m = 36 years
Hence age of Micah is 36 years.

What type of transformation of △ABC results in △DEF ?
Answer:
reflection
Step-by-step explanation:
Answer:
Reflection
Step-by-step explanation:
As you can see, its the same shape, and the same size...but it looked mirrored. ABC has been reflected over the y-axis to make DEF.
It's not rotation, because the shape has not been rotated, if so it would have been in a different position
It's not translation, because the shape didn't stay in the same format (facing one side).
So it must be reflection

find the value of n the equation 1/2(n+4)=6
Answer:
n = 8
Step-by-step explanation:
1/2(n + 4) = 6
1/2 of n + 2 = 6
6 - 2 = 4
4 × 2 = 8
1/2 of 8 + 2 = 6
4 + 2 = 6
n = 8

Can someone help me find the distance between the points (-5,3) and (-4,2)
Answer: 1.4142
Step-by-step explanation:
Input Data :Point 1 (xA,yA) = (-5, 3) Point 2(xb,yB) = (-4, 2)
Objective : Find the distance between two given points on a line?
Formula :Distance between two points = √(xB-xA)^2+(yB−yA)^2
Solution :
Distance between two points = √(−4−−5)2+(2−3)2= √12+(−1)2= √1+1= √2 = 1.4142
Distance between points (-5, 3) and (-4, 2) is 1.4142

Find the volume of the cylinder and cone, then add them together.
★ Volume of cylinder :-
V = πr²hHere,
r is radius h is heightWe have :
r = 2cm h = 7cmSubstituting the values :
> V = π (2 × 2) × 7
> V = 4π × 7
> V = 28π
★ Volume of cone :-
V = ⅓ π²hWe have :
r = 2cm h = 6 cmSubstituting the values :
> V = ⅓ × π × (2 × 2) × 6
> V = ⅓ × π × 4 × 6
> V = ⅓ × π × 24
> V = 8π
★ According to the question :-
Adding them together,
> Total Volume = 8π + 28π
> Total Volume = 36π
[tex]Total \: \: \: Volume = (88+176) {cm}^{2} \\ \\ = 264 {cm}^{2} .[/tex]

the graph of y=f(x) is shown on the grid
Answer:
Equation for M → g(x) = [tex]\frac{5}{4}x^{2} + 2[/tex]
Equation for N → h(x) = [tex]\frac{5}{4}(x+4)^2-1[/tex]
Step-by-step explanation:
Vertex of the graph of y = f(x) is (2, -1)
Therefore, equation of the function will be,
y = a(x - 2)² - 1
Since this graph passes through a point (0, 4),
4 = a(0 - 2)² - 1
4 = 4a - 1
a = [tex]\frac{5}{4}[/tex]
Hence, we get the equation of the function 'f' as,
f(x) = [tex]\frac{5}{4}x^{2} -1[/tex]
Now this graph has been shifted 3 unit up to get the new graph M
Equation for M will be,
g(x) = f(x) + 3
g(x) = [tex]\frac{5}{4}x^{2} - 1 + 3[/tex]
g(x) = [tex]\frac{5}{4}x^{2} + 2[/tex]
Further graph of function 'f' is shifted 4 units to the left then equation of the new function (N) will be,
h(x) = f(x + 4)
h(x) = [tex]\frac{5}{4}(x+4)^2-1[/tex]

Step-by-step explanation:
zach read a book10 min every weekend for the first month 20min in 2nd month 40 min in third month and 80 min in 4th month
victoria read a book 35 everyweekend for first month 50 min second month 65 min third month 80 min 4 the month which method is used linear or exponential
Answer:
Zach time of reading every weekend forms a sequence with these terms: 10, 20, 40, 80. On the other hand, that of Victoria forms a sequence with terms: 35, 50, 65, 80. By keenly observing the sequences, Zach's sequence is a geometric sequence with a common ratio equal to 2 and Victoria's sequence is an arithmetic or linear sequence with a common difference of 15. Thus, the answer is letter B.

What is the solution of 3sqrtx+8=-4
Answer:
No solution
Step-by-step explanation:
Please write this as 3 sqrt x + 8 = -4.
Note that if we try to isolate 3 sqrt x by subtracting 8 from both sides, we get 3 sqrt x = -12. There is no real solution; sqrt x can never be negative.

Find the slope of the line that passes through(9,36) (93,-10)?
Answer:
[tex]m = -\frac{23}{42}[/tex]
Step-by-step explanation:
here is the equation for slope (m):
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
where:
y₂ = y-coordinate of 2nd point = -10
y₁ = y-coordinate of 1st point = 36
x₂ = x-coordinate of 2nd point = 93
x₁ = x-coordinate of 1st point = 9
plug values into equation:
[tex]m =\frac{-10-36}{93-9} \\\\m = \frac{-46}{84} \\[/tex]
reduce the fraction:
[tex]m = -\frac{23}{42}[/tex]
The equation that Passes through the points (-4,2) and (5,-3)
Answer:
m= -5/9
Step-by-step explanation:
m= y2-y1/ x2-x1
m= -3-2/ 5-(-4)
m= -3-2/ 5+4
m= -5/9
y= mx + b
(-4,2)
2= -5/9(-4) + b
2= 2.2+ b
-2.2 +2= b
-0.2= b
A large rectangular movie screen in an IMAX theater has an area of 7,875 square feet. Find the dimensions of the screen if it is 30 feet longer than it is wide.
Answer:
Width=75
length=105
Step-by-step explanation:
Width=x
length=30+x
= 7875=x*30+x
x^2+30x-7875=0
x^2+105x-75x-7875=0
x(x+105)-75(x+105)=0
