Answer:
Mrs. Murphy bought 4 packages of paper lanterns, 12 bags of balloons, 11
garlands and 4 banners
Step-by-step explanation:
I'm not really sure how I got this but it hope it helps!
Let
x-------------> length of the side of a square
[area of a square]=x*x------> x²
[area of rectangle]=[shorter side]*[<span>longer side]
</span>[shorter side]=0.90 x-------> (<span>is 10% percent less than the length of a side of square)
</span>[longer side]=1.10x-------> (<span>is 10% percent more than the length of a side of square
</span>
[area of rectangle]=(1.10x)*(0.90x)-----> 0.99x²
[the ratio of the area of rectangle to the area of square]=0.99x²/x²=0.99
the answer is
the ratio of the area of rectangle to the area of square is 0.99
Answer:
y-2=2(x-6)
Step-by-step explanation:
y-y1=m(x-x1)
m=2
y-2=2(x-6)
Answer:
6) x=9.75
10) Triangle OMN ~ Triangle ODK; SSS ~
11) SSS ~ theorem
12) SSS ~ theorem
Step-by-step explanation:
For #6, since the polygons are similar, then it must mean AD is congruent to JM and CD is congruent to LM. Now we can set up the proportion 39/20=x/5 and solve. Solving for x gets us x=9.75, so C is the correct choice
For #10, there's no information about angles whatsoever in the diagram, so B and C must be wrong. D must be wrong as well because if the triangles weren't similar, then why is OJ ~ JM and OK ~ KN? So thus, the triangles are similar by SSS.
For #11, this is sort of a no-brainer because there's no mention of angles, so D must be correct.
For #12, same concept, no mention of angles, all sides are similar to their respective sides of the different triangles, so A is correct.
