Answer:
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion . In other words, similar triangles are the same shape, but not necessarily the same size. The triangles are congruent if, in addition to this, their corresponding sides are of equal length.Step-by-step explanation: ratios
Well, 12 issues end up as 960 pages total
so... if in 960 pages, 384 are ads, what about 80 pages?
well

solve for "x"
1. 130°
I don't remember too many specifics from my past math classes, but I always remembered this because that is an upside-down mirror of the 130° angle.
2. 50°
A straight line is 180°, and 180 - 130 = 50.
Answer:
Left 7
Step-by-step explanation:
f(x)=a(x-h)^2+k
f(x)=(x-(-7))^2
-7 of x is to the left
Answer:
The repeating decimal cost
a) As a fraction = $
b) As a mixed number = $ 
Step-by-step explanation:
The cost of making a computer component
= $3.161616
= $ 3 + 0.161616
Looking at the repeating decimal it is in 6 decimal places, hence to convert it to a fraction,
0.161616/ 1000000 × 1000000
= 161616/1000000
Therefore, the cost of making the computer component =
$3 + $161616/1000000
Step 1
We convert to a fraction
$3 + $161616/1000000
We find the LCM = 1000000
($3 × 1000000)+ ($161616× 1)/1000000
3000000 + 161616/1000000
= $ (3161616/1000000)
As a Mixed number =
