Step-by-step explanation:
½× 10 × 5√3 cm² =
25√3 cm²
or
43.30 cm²
Answer:

Step-by-step explanation:
y-0.8x=0.5
y*10-0.8x*10=0.5*10
10y-8x=5
10y-8x+8x=5+8x
10y/10=5/10+8x/10
y=5+8x/10
5*5+8x/10-2.5
8x+5/2-2.5=4x
y=5+8x/10, x=x
This is the concept of scale factors, if figure 1 was dilated to figure 2 the scale factor was given by;
scale factor=[length of figure 2]/[length of figure 1]
length of figure 1=18
length of figure 2 =3
thus;
The scale factor of the dilation will be:
3/18
=1/6
Answer:
3:1
Step-by-step explanation:
brown:black
15:5
Divide both sides by five;
15/5 :5/5
= 3:1
