You start by adding up all the socks, so 12+8=20 then you set up the ratio 8/20 and you simplify it, and the gcm is 4 so you would divide each by 4 which would give you a 2/5 ratio which is option "A"! hope this helps!
Answer:
total area = 39.6 square units
Step-by-step explanation:
determine the inside angle
360 / 5 = 72°
half of the triangle = 36°
given:
adj = 3.3
Ф = 36°
length of the opp of a small triangle is = adj. tan Ф
opp = 3.3 * tan 36 = 2.4
area of a triangle = 1/2 b * h x 2 tringles
area =( 1/2 * 2.4 * 3.3 ) * 2
area = 7.92 multiplied by 5 equal shapes
total area = 7.92 * 5
total area = 39.6 square units
hope this helps
Answer:
A
Step-by-step explanation:
Look at both rectangles and list each of the corners coordinates:
The rectangle on the left has coordinates:
R: (-4,-1)
S: (-1,-1)
T: (-1,-3)
U: (-4,-3)
Now because the rectangle transformed to a different location we should take the coordinates of each of its vertices to find what type of transformation this is:
R' : (4,-1)
S' : (1,-1)
T' : (1,-3)
U' : (4,-3)
We can notice that the difference between both sets of points is that the x-value changes sign and the y-values stay the same, therefore the answer is A
