Answer:
5.4cm
Step-by-step explanation:
In similar triangles, the perimeter of the triangles will be in the ratio of their corresponding sides.
The ratio of their perimeter is
perimeterofΔ2 15
--------------------- = -------------
perimeterofΔ1 25
So, the side of triangle 2 will be
9 * 15 15
---------------- = --------------
sideofΔ2 25
=
⟹side of Δ2= 25 / 9∗15 =5.4.
The answer is circumference
Answer:
Please see below :)
Step-by-step explanation:
y - 5 = -(x + 11) + 2
y - 5 = -x - 11 + 2
y = -x - 11 + 2 + 5
y = -x - 9 + 5
y = -x - 4
54x + 15 = -3(3y + 1)
54x + 15 = -9y - 3
54x + 15 + 3 = -9y
54x + 18 = -9y
-6x - 2 = y
y = -6x - 2

Known, density= mass/ volume
The volume is given as 200ml
Set up an equation and cross-multiply
You get mass = 180g, answer is B
Answer:
14(y + 2).
Step-by-step explanation:
32 +2/3(21y - 6)
Distributing the 2/3 over the parentheses:
= 32 + 2/3*21y + 2/3 * -6
= 32 + 14y - 4
= 14y + 28
= 14(y + 2).
