Assume that A ABC= A POR. Which of the following congruence statements are correct? Check all that apply. A. AB = OR B. BE PO C.

yulyashka [42]

For congruence of triangles.

If;

$\Delta ABC\cong\Delta PQR$

Then the corresponding sides and angles will be equal.

$\begin{gathered} AB=PQ \\ BC=QR \\ AC=PR \\ \measuredangle A=\measuredangle P \\ \measuredangle B=\measuredangle Q \\ \measuredangle C=\measuredangle R \end{gathered}$

Only the above congruence statements are true.

Any options that has any of the above congruence statement is true.

If n = 5 and r = 3 Find "Cr.

Marat540 [252]

Answer:

Cr = 10

Step-by-step explanation:

To calculate combinations we use the nCr formula: nCr = n! / r! * (n - r)!, where n = number of items, and r = number of items being chosen at a time.

$C(n,r)=[?]$

$C(n,r)=C(5,3)$

$=\frac{5}{(3!(5-3)!)}$

$=\frac{5!}{3!*2!}$

$=10$

What is the halflife

blagie [28]

To model half-life, use the formula $A(t)=A_0 (\dfrac{1}{2})^{ \frac{t}{t_{1/2}}$ . Here, $A(t)$ is the amount remaining after a length of time $t$ . $A_0$ is the amount that you start with. $t_{1/2}$ is the half-life. You plug in 50 for $t_{1/2}$ , 10 for $A_0$ , and 25 for $t$ . You get $A(t)=10( \frac{1}{2})^{25/50} = 10( \frac{1}{2})^{1/2} = 7.07 \ grams$ .
