As per the combination method, there are 15 different ways are possible for this situation.

Combination method:

Combination method also known as NCR is a formula of combination and arrangement, where the object's order does not matter so much.

Given,

Here we have to find the number of ways to be selected as the best student and another student is to be selected as a runner-up among the 6 students.

Here we know that that the value of

Total number of students = 6

Best student = 1

Runner - up = 1

So, as per the NCR formula, the value of n = 6 and the value of r = 2

Then the possible combinations are calculated as,

=> ⁶C₂ = 6! / 2!(6 - 2)!

=> ⁶C₂ = 6!/2!4!

=>⁶C₂ = 15

Therefore, the resulting number of ways is 15.

If QRS TUV, which congruences are true by CPCTC? Check all that apply.
Morgarella [4.7K]

It is given thatΔ QRS ≅Δ TUV

Out of all the given options

(C) QS= TV [C P C T}

(D) QR =TU

(E) S = V

(F) R= U

C, D,E, F are correct options.

Because when two triangles are congruent their corresponding parts are equal.

CPCT means corresponding parts of congruent triangles.

All these options are congruent by CPCT.

Side QR is congruent to TU.

Side Q S  is congruent to TV.

Angle S is Congruent to Angle V.

Angle R is congruent to Angle U.

The meaning of congruency of shapes is that the two or many more shapes are identical.

F(x) = -2x + 5<br> f ( ) = 13
scZoUnD [109]

Answer:

Okay, I haven't done this a long time however I believe with this you have to solve the equation by doing substitution.

Step-by-step explanation:

so, if f (x) equals 13, you replace the x in the equation to 13.

f(x)=-2x+5

f(x)=-2(13)+5

f(x)=26+5

f(x)=31

I believe 41 would be your answer. Hope this is right and it helped!

2x squared + 9x=-5 i need to solve for x
In-s [12.5K]
2x^2+ 9x=-5 \\ \\2x^2 + 9x+5 =0 \\\\a=2, \ \ b=9 , \ \ c=5 \\\\\Delta =b^2-4ac = 9^2 -4\cdot 2\cdot 5 =  81-40=41 \\ \\x_{1}=\frac{-b-\sqrt{\Delta} }{2a}=\frac{-9-\sqrt{41}}{2\cdot 2 }=\frac{-9-\sqrt{41}}{ 4 }\\\\ x_{2}=\frac{-b+\sqrt{\Delta} }{2a}=\frac{-9+\sqrt{41}}{2\cdot 2 }=\frac{-9+\sqrt{41}}{4 }

Evaluate the following<br><br> (1.6 x 10 12) ÷ (8.01 x 10 23)
devlian [24]
To evaluate the given expression, we must follow the rules of PEMDAS (Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction) in solving.

Therefore, first calculate what's inside the parentheses:

(1619.2) / (8194.23)

 Then perform the operation in between the parentheses:

<span>(1619.2) / (8194.23) = 0.20
</span>
Therefore the answer after evaluating the expression is 0.20.


I hope my answer has come to your help. Thank you for posting your question here in Brainly.
