Okay well I do it like this. 3+8=11. I put a 1 down and carry the other. so I do 7+0+1=8 so now I have 81, and last I do 6+3=9. so the answer would be 981.
Have a nice day!
12X is the period of what is the period of f : R→R, f(x) = tan(x 3)?
Answer:
20 -> 10 × 2 (2 is prime)
10 -> 5 × 2 (both are prime)
So you have 2 × 2 × 5, which can also be written as 2² × 5, which is your answer. I hope this helps!
Step-by-step explanation:
Let's go through the possible answer choices one by one
A) BE is congruent to ED
This is true because "BE" and "ED" are formed by the first two letters of BEC and DEC respectively. The triangles are congruent, so the corresponding sides must be congruent. To name a segment, the order does not matter. Writing "DE" is the same as "ED".
B) AC is congruent to BD
False. Point A isn't mentioned at all. We don't know for sure how point A fits in. The statement may be true, or it could easily be false as well. We don't have enough info.
C) Angle BEC = angle DCE
False. The order of the letters is very important. For angle BEC, we have E in the middle so the vertex of the angle is at point E. For angle DCE, the vertex is at point C. If angle BEC = angle DCE, then E and C must correspond; however they don't. Back up at the top, it says "DEC is congruent to BEC", so we see that E corresponds to E, and C corresponds to C.
D) angle BCA = angle BCD
False. Again we don't know anything about point A. The same issues come up as they did with choice B.
The only true result is choice A
Answer:
She will pay less at store B
Step-by-step explanation:
30% off of $612 is $428.4
25% off of $612 is $459
Remember she has a coupon for 10% off
10% off of 459 is $413.1
She would save $198.9
