Based on this information, the balance in the cash account at the end of January would be: Multiple Choice

Answer: $12,975 Explanation: To find the balance in the cash account at the end of January, we need to consider all cash inflows and outflows. This involves adding any cash received and subtracting any cash paid out. Steps: Initial Cash Investment: Andrea invested $13,500 cash. Cash inflow: $13,500 Cash Received for Services: The company received […]

16. Triangle JKL and triangle PQR are shown above. If ∠J is congruent to ∠P, which of the following must be true in order to prove that triangles JKL and PQR are congruent? A. ∠L ≅ ∠R and JL = PR B. KL = QR and PR = JL C. JK = PQ and KL = QR D. ∠K ≅ ∠Q and ∠L ≅ ∠R

16. Triangle JKL and triangle PQR are shown above. If ∠J is congruent to ∠P, which of the following must be true in order to prove that triangles JKL and PQR are congruent? A. ∠L ≅ ∠R and JL = PR B. KL = QR and PR = JL C. JK = PQ and KL = QR D. ∠K ≅ ∠Q and ∠L ≅ ∠R

Answer: A. \(\angle L \equiv \angle R\) and \(JL = PR\) Explanation: To prove that triangles \(JKL\) and \(PQR\) are congruent, we can use the Angle-Side-Angle (ASA) Congruence Theorem. This theorem states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, […]

Pedro is going to use SAS to prove that △PQR ≅ △SQR. Which of these is a necessary step in Pedro’s proof? A. Prove that ∠QPR ≅ ∠QSR by the Isosceles Triangle Theorem. B. Prove that QR ≅ QR by the reflexive property. C. Prove that PQ ≅ SQ by CPCTC. D. Prove that ∠PQR ≅ ∠SQR by vertical angles.

Pedro is going to use SAS to prove that △PQR ≅ △SQR. Which of these is a necessary step in Pedro's proof? A. Prove that ∠QPR ≅ ∠QSR by the Isosceles Triangle Theorem. B. Prove that QR ≅ QR by the reflexive property. C. Prove that PQ ≅ SQ by CPCTC. D. Prove that ∠PQR ≅ ∠SQR by vertical angles.

Answer: B. Prove that \( \overline{QR} \cong \overline{QR} \) by the reflexive property. Explanation: To prove that \(\triangle PQR \cong \triangle SQR\) using the Side-Angle-Side (SAS) congruence theorem, we need to establish that two sides and the included angle of one triangle are congruent to two sides and the included angle of the other triangle.

5712-3984= ?

Answer: 1728 Explanation: To find the difference between 5712 and 3984, subtract 3984 from 5712: \[ 5712 – 3984 = 1728 \]

2) Mr Lim gave 3600 to his wife and two children altogether. His wife received 500 more than his son. His son received twice as much as his daughter. How much did Mr Lim’s wife received? (W.Bk 5A : pg 28 #6)

2) Mr Lim gave 3600 to his wife and two children altogether. His wife received 500 more than his son. His son received twice as much as his daughter. How much did Mr Lim's wife received? (W.Bk 5A : pg 28 #6)

Answer: $1,700 Explanation: To solve this problem, we use algebraic equations to represent the relationships between the amounts received by Mr. Lim’s wife, son, and daughter. We set up equations based on the given conditions and solve for the unknowns. Steps: Define Variables: Let \( x \) be the amount the daughter received. Then the […]

4 A radio station is giving away tickets to a play. They plan to give away tickets to seats that cost 10 or 20. They plan to give away at least 20 tickets, and the total cost of all the tickets can be no more than $300. Make a graph showing how many tickets of each kind can be given away. x + y ≥ 20 10x + 20y ≤ 300

Math Question from Image

Answer: The feasible region for the number of tickets that can be given away is defined by the inequalities \( x + y \geq 20 \) and \( 10x + 20y \leq 300 \). Explanation: This problem involves linear inequalities and graphing a feasible region. The goal is to determine how many tickets of each […]
