If you are always included to lead, that leaves 10 students to choose from.
If all that is important is being selected, then there are 10C3 = 120 ways to choose them.
If each selection has a unique duty, then there are 10P3 = 720 ways to assign them their jobs.
Answer: 10P3=720

10.9 + (-15.6) + 2.1 write as a decimal
Answer:
-2.6
Step-by-step explanation:
10.9 + (-15.6) becomes 10.9 - 15.6 which equals -4.7. The last step is to add the 2.1 to the -4.7: -4.7 + 2.1 = -2.6
Therefore the answer is -2.6
The value of the expression 10.9 + (-15.6) + 2.1 will be negative 2.6.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
The decimal number is the sum of a whole number and part of the fraction number. The fraction number is greater than zero but less than one.
The expression is given below.
⇒ 10.9 + (-15.6) + 2.1
⇒ 10.9 - 15.6 + 2.1
⇒ 13 - 15.6
⇒ - 2.6
The value of the expression 10.9 + (-15.6) + 2.1 will be negative 2.6.

What are the coordinates of the image of vertex R after a
reflection across the y-axis?
O (4,3)
O (4, -3)
0 (-3,-4)
O (3, 4)
Answer:
D
Step-by-step explanation:
The coordinates of the image of vertex R after a reflection across the y-axis is (4,-3), the correct option is B.
What is a reflection?A reflection can be defined as a type of transformation which moves every point of the object by producing a flipped but mirror image of the geometric figure. Consider a plane. Consider a design or shape on that plane. Now consider an axis.
If we think of that axis as a mirror, and on the opposite side of that axis create the image of the considered shape, then if the shape's image looks exactly as the shape itself, then that shape is called to have a reflectional symmetry.
We are given that;
The vertex R=(-4,-3)
Now,
When reflecting a point across the y-axis, the x-coordinate changes its sign, while the y-coordinate remains the same. Therefore, the image of vertex R(-4,-3) after reflection across the y-axis would be the point (4,-3), since its x-coordinate changes its sign and its y-coordinate stays the same.
Therefore, by reflection the answer will be (4,-3).

Answer:
A. m∠ 2= 41°
B. m∠4 =61°
Step-by-step explanation:
Compliment means that the two angles will add up to 90°, and Supplement means to add up to 180°.
A. m∠1 + m∠2 = 90°
49°+ m∠2 = 90°
m∠2 = 90° - 49°
m∠2 = 41°
-----------------------------------------------------------------------------
B. m∠3 + m∠4 = 180°
119 + m∠4 = 180°
m∠4 = 180° - 119°
m∠4 = 61°

Find the area of the shape shown below.

Split it into two shapes a square and a triangle.
Square = 3 x 3 = 9
Triangle = 1/2 x base x height
The height would be the side of the square = 3
The base would be the length of the top line minus the length of the side of the square = 7-3 = 4
1/2 x 4 x 3 = 6
Total area = 6 + 9 = 15 square units.
Answer:
15 sq. unitsStep-by-step explanation:
area of a trapezoid = (a + b) * h/2
where a = 3, b = 7, h = 3
plugin values into the formula:
A = (3 + 7) * (3/2)
A = 15 sq. units.

I only see one question here...
If [tex]y=f(x)[/tex] is a one-to-one function, then it has an inverse such that [tex]f^{-1}(y)=x[/tex]. This means that [tex]f^{-1}(f(x))=x[/tex].
According to the table, [tex]f(1)=-2[/tex]. So by definition of the inverse, we have
[tex]f(1)=-2\implies f^{-1}(f(1))=f^{-1}(-2)\implies\boxed{1=f^{-1}(-2)}[/tex]
so the answer is either B or D (they're both the same...)

Which is the point-slope form of a line that passes through the point (12, 31) with a slope of 7/3?
Answer:
y - 31 = 7/3(x - 12)
Step-by-step explanation:
Point slope form is: y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point
Plug in the slope and the given point:
y - y1 = m(x - x1)
y - 31 = 7/3(x - 12)
So, the point-slope form of the line is y - 31 = 7/3(x - 12)

Answer:
slope is 1
Step-by-step explanation:
when the x-axis is zero the y-axis is the slope
Answer:
y = 2x + 1
Step-by-step explanation:
Slope intercept form is y = mx + b, where m is the slope and b is the y-intercept. When we look at the graph we see that at x = 0 our y-value is 1. This is our y-intercept meaning that b = 1. To find the slope of the line, you divide the difference in the y-values between 2 points on the line by the difference in the x-values between 2 points on the line. Let's choose 2 points! Our 1st point is going to be (0,1) and our second point is (1,3).
[tex]m=\frac{3-1}{1-0}=\frac{2}{1}=2[/tex]
After we have found both our m and b value, we simply plug in these numbers into the slope intercept form.
m = 2
b = 1
y = 2x + 1

A recipe for salad dressing requires oil abd vinegar oil in a ratii of 3:2 which set of ingredients creates dressing with the same ratio?
Answer:
Step-by-step explanation:
Oil 3 parts in the basic relationship. So try 12
Vinegar 2 parts so call it x.
3/12 = 2/x Cross multiply
3x = 2*12 Combine the right
3x = 24 Divide by 3
3x/3= 24/3
x = 8
So 12:8 is the same as 3:2
