3. It has 3 symmetrical lines, so, therefore, has 3 lines of reflectional symmetry.
Hope this helps!

C= 50y+20x
Where y is the number of boxes holding 50 pieces each and x is the number of boxes holding 20 pieces each.
Answer: 27465 km/h
Step-by-step explanation:
From the figure, let us use cosine formula to calculate the resultant displacement.
B^2 = C^2 + A^2 - 2(A)(C) cosØ
Where C = 580km
A = 360 km
Ø = 153 degree
Substitute all the parameters into the formula
B^2 = 580^2 + 360^2 - 2(360)(580)cos153
B^2 = 466000 - ( - 372084.32 )
B^2 = 466000 + 372084.32
B^2 = 838084.32
Square root both sides
B = 915.5 km
You are told to use a scale of 1 cm to 50 km.
Therefore, B = 915.5/50 = 18.3 cm
The time given are: 09:23 and 09:25.
The time difference = 25 - 23 = 2 minute.
Convert minutes to hours
2 minute = 2/60 = 1/30 hours
Speed = distance/time
Speed = 915.5 ÷ 1/30
Speed = 915.5 × 30
Speed = 27465 km/h
Or
Convert 2 minute to second
2 minute = 2 × 60 = 120 seconds
Speed = distance/time
Speed = 18.3/120
Speed = 0. 1525 cm/s
2x - 7 = 8x - 47 - (3x - 14) / 2
combine like terms
0= 6x - 40 - (3x-14)/2
(3x-146) / 2
isolate x
x=22/3
your final answer would be x=22/3
Answer:
3.6
Step-by-step explanation:
if 0.45 is 1 pound then you could do 8 x 0.45 because the baby is 8 pounds
