Answer:
203.5 N
Step-by-step explanation:
Force = mass × acceleration
F = ma
F = (55 kg) (3.7 N/kg)
F = 203.5 N
<h3>
Answer: Choice A</h3>
Angle M = Angle T, Angle G = Angle Y, Angle B = Angle T
MG = WY, GB = YT, MB = WT
The order of the letters of MGB and WYT is important.
We have M and W as the first letters of their respective sequences. So M and W pair up and they are congruent angles. Only choice A shows this. Every other answer choice has M paired with the wrong angle.
Similarly, the second letters G and Y pair up and they are congruent. So are the third letters B and T.
The segments pair up in a similar fashion. For instance, M and G are the first two letters of MGB, W and Y are the first two letters of WYT, so segment MG and WY pair up and are congruent. The other segments follow that pattern as well.

Answer:
The determinant is 15.
Step-by-step explanation:
You need to calculate the determinant of the given matrix.
1. Subtract column 3 multiplied by 3 from column 1 (C1=C1−(3)C3):
![\left[\begin{array}{ccc}-25&-23&9\\0&3&1\\-5&5&3\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-25%26-23%269%5C%5C0%263%261%5C%5C-5%265%263%5Cend%7Barray%7D%5Cright%5D)
2. Subtract column 3 multiplied by 3 from column 2 (C2=C2−(3)C3):
![\left[\begin{array}{ccc}-25&-23&9\\0&0&1\\-5&-4&3\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-25%26-23%269%5C%5C0%260%261%5C%5C-5%26-4%263%5Cend%7Barray%7D%5Cright%5D)
3. Expand along the row 2: (See attached picture).
We get that the answer is 15. The determinant is 15.
