Answer:
3900
Step-by-step explanation:
We want the sum from 5 to 195
5, 10, 15, 20,......195
an = 5 + 5(n-1) since we can write this as an arithmetic sequence, adding 5 each time
The sum of the terms of an arithmetic sequence is given by
Sn = n/2 [2a1 + (n - 1)d],
where d is the common difference of 5 and n is the term we want to add to
195/5 = 39 so it is the 39th term
s39 =39/2 [2*5 + (39-1)*5)]
s38 = 19.5[10+38*5]
=19.5*[10+190]
19.5*200
=3900
Answer: C) ΔUVW and ΔRST are congruent
Step-by-step explanation:
- Rigid motions move a geometric figure but do not change the size and shape of the figure.
- It produces congruent images.
There are four kinds of rigid transformation.
1) translation 2) reflection 3) rotation 4) glide reflection.
If a series of rigid motions maps ΔUVW onto ΔRST.
Then, ΔUVW and ΔRST must be congruent. (No change in size or shape)
hence, the correct statement is C) ΔUVW and ΔRST are congruent.
