Ritta purchased a package of stickers. She noticed 4 out of every 5 stickers where purple. Which table shows the relationship be
lisabon 2012 [21]

Answer:

4:5

Step-by-step explanation:

I don't see the table but since it is 4 out of every 5 stickers are purple, the ratio would be 4:5, 4/5, or 4 to 5. It doesn't really matter, because all of these mean the same thing.

Tell me if I'm wrong :)

-The dimensions of a rectangular garden were 2 m by 4 m. Each dimension was
posledela

Answer: 4 m

Step-by-step explanation:

Let the amount each dimension was increased by be x.

Now we can set up a equation.

(2+x)(4+x) = 48

8 + 2x + 4x + x^2 = 48

x^2 + 6x - 40 = 0.

We can factor the left side of the equation.

(x+10)(x-4) = 0.

Therefore, x equals either -10 or 4. Since you can't increase a dimension by a negative amount, x must equal to 4.

Thinking the perimeter of the rectangle is 3x + 2 + x + 3x + 2 + X.
givi [52]
They are both right because the first expression is the perimeter but expanded in terms of length.The second expression is shortened to be a factor expression but they both represent the length.
The benefit of the first one is you can see how it’s expanded and plug the numbers in and the second one is more easy to plug in the numbers with ease.

Answer:

1. x²=a² + b²

x²=10²+7²

x²=100+49

x²=149

x=√149

12.206555615

x=12.2

2.x²= a²+b²

x²=19²+ 21²

x²=361+441

x²=802

x=√802

x=28.319604517

x=28.3

3.x²=a²+b²

x²=27²+16²

x²=729+256

x²=985

x=√985

x=31.384709652

x=31.3

4.x²=a²+b²

x²= 163.84+ 28.109

x²=191.93

x=√191.93

x=13.853880322

x=13.9

<span>Step three: Multiply .633 * 100 to change it to a percent. It becomes 63.3% (rounded) </span>
<span>The decrease is 63.33% </span>

<span>Proof: $15 * .63333 = $9.50 </span>
