Answer:
8/5 or 1 3/5 ft
Step-by-step explanation:
The area of a rectangle is given by
A = l*w
The area is 4/5 and the width is 1/2
4/5 = 1/2 *l
Multiply each side by 2
2*4/5 = 2*1/2 *l
8/5 = l
Changing to a mixed number
l = 1 3/5
Answer:
C = 18.1°
Step-by-step explanation:
A = 142 m²
a = 24 cm, b = 38 cm
Use the formula A = a*b*sinC/2
142 = 24 * 38 * sinC/2 = 456*sinC
sinC = 0.3114
C = 18.1°
Answer:
$ 12.4
Step-by-step explanation:
i have got $ 12.4
24/8
= 24÷8
= 3
Final answer is 3
You need an even number of reflections to get the original figure, leaving only A and D as potentially viable choices.
The reflection across the x-axis makes the tranformation (x, y) ⇒ (x, -y).
The reflection across the line y=x makse the transformation (x, y) ⇒ (y, x).
The two pairs of transformations of A give
(x, y) ⇒ (x, -y) ⇒ (-y, x) ⇒ (-y, -x) ⇒ (-x, -y) . . . . . not the original
The reflection across the y-axis makes the transformation (x, y) ⇒ (-x, y).
The two pairs of transformations of D give
(x, y) ⇒ (y, x) ⇒ (y, -x) ⇒ (-x, y) ⇒ (x, y) . . . . . . the original point
Selection D is appropriate.
