2.2 with the decimal 2 repeating
Answer:
around 13.18
Step-by-step explanation:
the middle square is 2*2 = 4
the triangle then is 2^2 + 6^2 = 40 -> sqrt40 = 6.325
and then 2^2 + 2^2 = 8 -> sqrt8 = 2.828
4+6.325+2.828 = 13.18
Step-by-step explanation:
If segment AD contains point B and, then A, B, C and D lies on the same straight line as shown in the attachment.
To show that point C is the middle of point BD, we musr show that segment BC is equal to CD i.e BC = CD.
From the diagram, AC = AB+BC
Given AC = 12cm and AB = 4cm
BC = AC-AB
BC = 12cm - 4cm
BC = 8cm
Also AD = AB+BC+CD
Given AD = 20cm, AB = 4cm and BC = 8cm
CD = AD-(AB+BC)
CD = 20-(4+8)
CD = 20-12
CD = 8cm
It can be seen that BC = CD = 8cm, hence C is the midpoint of B and C.
When an object is reflected over the y axis you simply multiply every x variable by -1. The vertices are P(-2,-4), Q(5,3), and R(1,-2)
Answer:
21
Step-by-step explanation:
so if the ratio is 3:4
then we can also write the ratio as 3x:4x
where the total is 7x marbles and we see we have to chose the one that is divisible by 7 which is 21.
