Answer:
3. Sides: Equilateral
Angles: Acute
4. Sides: Isosceles
Angles: Right
Step-by-step explanation:
3. Sides: Equilateral because in an equilateral triangle all sides are equal.
Angles: Acute because in an acute triangle all angles are acute.
4. Sides: Isosceles because in an isosceles triangle two legs are equal.
Angles: Right because in a right triangle, one angle is right.
Old price: p1 = $ 3.90;
New price: p2 = $ 3.40.
The percentual decrease is given by
d(%) = [ (p2 - p1) / p1 ] * 100 %
d(%) = [ (3.40 - 3.90) / 3.90 ] * 100 %
d(%) = [ - 0.50 / 3.90 ] * 100 %
d(%) = - 0.128 * 100 %
d(%) = - 12.8 % (approximately)
So the price fell 12.8 % approximately.
I hope this helps. =)
L = X
w = X - 8
P = 52 cm
P = 2l + 2w
52 = 2(X) + 2(X - 8)
52 = 2x + 2x - 16
52 + 16 = 4x
68 = 4x
68/4 = 4x/4
17 = X.
The length of the rectangle is 17 cm.
W = X - 8
W = 17 - 8
W = 9 cm.
The width of the rectangle is 9 cm.

Answer: 62.5 yards
Step-by-step explanation:
So we can make a ratio:
2 minutes : 25 yards
2:25
Simplify:
1:12.5
Times 5 by 1 minute to get 5 minutes
Whatever you do to one side do to another
5:62.5
62.5 yards
