Hey there!

A reciprocal might be an unfamiliar vocab word, but the concept is really quite simple.

It's just a flipped fraction! Multiplying the flipped fraction by it's reciprocal gets you one, and that's how you check your answer.

So we have:

Reciprocal of 9/10 is 10/9, because 9/10 times 10/9 = 90/90 = 1

Reciprocal of 1/11 is 11/1, because 1/11 times 11/1 = 11/11 = 1

Reciprocal of 10(remember, it's 10/1) is 1/10, because 10/1 times 1/10 = 10/10 = 1

Hope this helps!

A designer enlarged both the length and the width of a rectangular carpet by 60 percent. The new carpet was too large so the des
Snowcat [4.5K]

x= length, y=width

Both the length and width were increased by 60% so now they are:

1.6x and 1.6y

Then they were both reduced by 25% so now they are 75%(100-25) of their previous size so they are:

0.75(1.6x) and 0.75(1.6y)

Their area would be length * width so it would be:

0.75(1.6x) * 0.75(1.6y)

Simplified this would be:

1.2x * 1.2y

Simplified more it would be :

1.44xy which is also 144% of xy which is a 44% increase of the original area (xy)


So the answer is:

44%

The school is selling potted plants as a fundraiser.Kara sold 12 ferns and 8 ivy plants for $260.Paul sold 15 ivy plants and 6 f
vovangra [49]

x=ferns ; y=ivy

12x+8y=260

6x+15y=240

x=60 -(15/6)y

12(60+ (15/6)y + 8y = 260

x=60 -(15/6)y

720 - 30y + 8y = 260

x=60- (15/6)y

-30y +8y= 260-720 ==> -22y= -460

x=60 -(15/6)y

y= (-460)/(-22)= 20.9090909091

y=20.90

x=60 -(15/6)×20.90= 7.75

×(ferns)=7.75$

y(ivy)=20.90$
