Answer:
25% = 25/100 = .25
25% of 130 = .25(130) = $32.50
$32.50
if thats what you were saying
Step-by-step explanation:
3/9 = □/3
Do cross multiplication.
3/9 = □/3
3 × 3 = 9 × □
9 = 9 × □
9/9 = □
1 = □
◇ The missing number (□) is 1.

Answer:
AD = 4.5
Step-by-step explanation:
Since the two bases of the two given triangles are parallel the triangles are similar.
Triangle BDE is similar to Triangle BAC
From this the following proportion can be set up.
BE / BC = BD/BA
BE = 8
BC = 8+12 = 20
BD = 3
BA = 3 + x where x = DA
8/20 = 3/(3+x) Cross Multiply
8(3 + x) = 3 * 20 Remove the brackets on the left. Combine Right
24 + 8x = 60 Subtract 24 from both sides
8x = 60 - 24 Combine the right
8x = 36 Divide by 8
x = 36/8
x = 4.5
But x = AD

Step-by-step explanation:
Answer:
4![\sqrt{37}](https://tex.z-dn.net/?f=%5Csqrt%7B37%7D)
Step-by-step explanation:
Since the figure is a square, find the length of 1 side and multiply by 4 for perimeter.
Calculate the length of AB using the distance formula.
AB = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = A(3, 4) and (x₂, y₂ ) = B(2, - 2)
AB =
= ![\sqrt{(-1)^2+(-6)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%28-1%29%5E2%2B%28-6%29%5E2%7D)
= ![\sqrt{1+36}](https://tex.z-dn.net/?f=%5Csqrt%7B1%2B36%7D)
= ![\sqrt{37}](https://tex.z-dn.net/?f=%5Csqrt%7B37%7D)
Hence
perimeter = 4AB = 4![\sqrt{37}](https://tex.z-dn.net/?f=%5Csqrt%7B37%7D)
