Answer:
126 ways
Step-by-step explanation:
Total number of persons = 9
Number of commitees to be chosen = 4
Since, there is no order in the selection process, we use combination.
Choosing a committee of 4 from 9 will be :
9C4.
Recall :
nCr = n! / (n-r)!r!
9C4 = 9! / 5!4!
9C4 = (9*8*7*6) / (4*3*2*1) = 3024 / 24 = 126 ways

Estimate 11.14+9.543 by first rounding each number to the nearest tenth.
HELP PLSZZ
To round each number to the nearest tenth, we have to look at the second digit after the decimal point, the hundredths. We look at tenths to round whole numbers, hundredths to round tenths, thousandths to round hundredths, etc. If the digit is 4 or below, then we would round down. If the digit is 5 or up, we would round up.
11.14
The digit is below 5, so we round down to 11.1.
9.543
The digit is also below 5, so we round down to 9.5.
Henceforth, adding these two numbers, we can conclude that an accurate estimation of the sum is 11.1 + 9.5, or 20.6.
If we wanted to round this answer further, we would use the same rounding rule. 20.6, where the tenths place digit, 6, is above 5, would be rounded up to 21.

Write equation of a line through the points (4,2) and (6,-4)
Answer:
y = -3x - 2
Step-by-step explanation:
to find slope use m= y2-y1/x2-x1
m= -4-2/6-4
m= -6/2
m=-3
then use point slope formula (y-y1) =m(x-x1)
(y-2) = -3(x-4)
simplify
y-2 = -3x - 4
turn into slope intercept form
y = -3x - 2

What is the difference between a 30° angle and a -30° angle?
Please provide a complete sentence or two.
Answer:
See below
Step-by-step explanation:
A 30° angle is measured 30° counterclockwise while a -30° angle is measured 30° clockwise. Therefore, you can say -30°=360-30°=330° because 30° is a reference angle located in Quadrant IV.

TWO points A and B on a plan represent two localities 12 m apart. Given that the segment AB is 6 cm long, find the scale used to draw the plan.
Answer:
The scale used to draw the plan is 1: 200.
Step-by-step explanation:
Given that two points A and B on a plan represent two localities 12 m apart, to determine, given that the segment AB is 6 cm long, the scale used to draw the plan, the following calculation must be performed:
12 m = 12 cm x 100 = 1200 cm
1200/6 = 200
Therefore, the scale used to draw the plan is 1: 200.

Elena donates some money to charity whenever she earns money as a babysitter. What percent of her income does She donate?
Answer:
10%
Step-by-step explanation:
The question is incomplete due to missing data
Say she earns $1000
And she donates $100
Hence the percentage of her earnings she donates is
=100/1000*100
=10000/1000
=10%
Hence the percentage is 10%

❗️❗️❗️please answer fast‼️‼️‼️‼️
Answer:
72°
Step-by-step explanation:
The interior angles of a triangle sum to 180°. Since there are two angles at 54°, we can use the equation x = 180 - 54 - 54 or x = 180 - 2(54), which will give us 72°.

Sandy paid $27 for her new sweater. If the sweater was on sale for 25% off, what was the original price?
Answer:
The answer is $36
Step-by-step explanation:
Took the Star Math Test
Answer:
$36
Step-by-step explanation:
100% - 25% = 75%
75% as a decimal = 0.75
75% = 27
75% as a decimal = 3/4
So 3/4 x = 27
27 x 4 = 108
108 / 4 = 36

A. Reflection, translation
B. Reflection, rotation
C. Translation, translation
) D. Rotation, translation
Answer:
A
Step-by-step explanation:
A glide reflection is a composition of a line reflection and a translation that is parallel to the line of reflection. Unlike some composition of transformations, a glide reflection IS ____________________. Therefore, the line reflection and translation can be done in any ____________.
Answer:
" a glide reflection IS commutative. Therefore, the line reflection and translation can be done in any order."
Step-by-step explanation:
Transformations can be written as operators that act on functions or shapes.
For example, we can define the horizontal translation operator as:
T(k)
And if we apply this to a function, we get:
T(k)[ f(x) ] = f(x - k)
Now, the operators are not necessarily commutative.
This means that if we have two operators:
K and L
is not the same:
K[ L[ f(x) ]]
than:
L[ K[ f(x) ]]
An example of this can be a reflection across the y-axis and a horizontal translation, that composition is non-commutative.
Now, let's go to our case.
A glide reflection is commutative, so we can perform the transformations in any order, then the statement is:
" a glide reflection IS commutative. Therefore, the line reflection and translation can be done in any order."
y=3x +5
y=x+3

how to find compound intrest
Answer:
A = Accrued amount (principal + interest)
P = Principal amount.
r = Annual nominal interest rate as a decimal.
R = Annual nominal interest rate as a percent.
r = R/100.
n = number of compounding periods per unit of time.
t = time in decimal years; e.g., 6 months is calculated as 0.5 years

Use the information given to write the equation of the circle
Center: (-9, -3), Point on Circle: (-11,2)
x²+ y²+ 20x + 8y - 84 = 0 is equation of the circle .
What is a circle, exactly?
A circle is a closed, two-dimensional object in which all points in the plane are equally spaced apart from the center.
The symmetry line of reflection is formed by each line that traverses the circle. Additionally, it is rotationally symmetric about the center for all angles.
the equation of the circle with center (-10,-4) and a point on the required circle is (4,-2).
Clearly, radius of the circle will be distance between the center and the point on the circle.
r = √( -10 - 4 )²+ ( -4 + 2 )²
r = √196 + 4
r = 10√2
We know that circle with center at (h.k) and radius r has the equation
( x - h )² + ( y - k )² = r²
We have circle with radius 10√2 and center at (-10,-4) and its equation will be
( x+ 10 )² + ( y + 4)²= ( 10√2)²
x²+ y²+ 20x + 8y - 84 = 0
