Answer: 132
Step-by-step explanation: For day A the students payed 40 dollars and on day B they paid 92 so 40+92=$132 in all.
Answer:
B. -1, 2, -4, 8
Step-by-step explanation:
The characteristic of a geometric sequence is that adjacent terms have a common ratio. Sequence B is the only one.
2/-1 = -4/2 = 8/-4 = the common ratio: -2
___
Ratios of adjacent terms are different for the other sequences.
Answer:
Step-by-step explanation:
We have given a parallelogram ABCD.
For a parallelogram,
Opposite pair of sides are parallel to each other.
i.e AD is parallel to BC and AB is parallel to CD.
From the attached figure,
∡1 = ∡4 and ∡2 = ∡3 {If two parallel lines cut by a transversal line then alternate interior angles are congruent }
Next, AC ≅ AC {Reflexive identity}
hence, ΔABC ≅ ΔCDA , By Angle-Side-Angle(ASA) congruent property of triangle.
Therefore, AB = CD and AD = BC {Proved}
If you are adding a positive number to negative number. You are just bringing the negative number closer to zero, if not above zero.
