Answer:
r = 4.5 ft
Step-by-step explanation:
Circumference of circle = πd
πd = 9π ft
d = 9π ÷ π
d = 9 ft
Radius = d ÷ 2
= 9 ÷ 2
= 4.5 ft
Step by step solution :Step 1 :Equation at the end of step 1 : (((3•(x2))•(y4))3) 4•—————————————————— ((2x3•(y5))4) Step 2 :Equation at the end of step 2 : ((3x2 • (y4))3) 4 • ——————————————— 24x12y20 Step 3 : 33x6y12 Simplify ———————— 24x12y20 Dividing exponential expressions :
3.1 x6 divided by x12 = x(6 - 12) = x(-6) = 1/x6
Dividing exponential expressions :
3.2 y12 divided by y20 = y(12 - 20) = y(-8) = 1/y8
Equation at the end of step 3 : 27 4 • —————— 16x6y8 Step 4 :Final result : 27 ————— 4x6y8
It must be noted that if we speak of polygons being similar, it means that the ratio of the corresponding sides are proportional. Also, all the interior angles are congruent. Examples of proportion that would contain BC and KL are:
BC / NK = CD / KL
or;
AB / CD = MN / KL
There are still other proportions apart from what I presented above, would really appreciate if you establish them yourself.
I don’t think those are similar... not 100% sure tho. I think they need 2 matching angles to be similar.
Answer:
x= 1.5 Hope that helps!
Step-by-step explanation:
1. 12(5x-4.5)=36 First Divide both by 12 5x-4.5-36/12 = 3
2. 5x-4.5=3 add 4.5 to both sides
3. 5x= 3+4.5 = 7.5
4. 5x=7.5 divide both sides by 5 x=7.5/5= x=1.5
So, x=1.5 would be your answer. Can you make me Brainliest Please
