Question

PLease help me!!

The figure below shows two similar pictures that Enrique wants to frame. Enrique has 4 strips of unfinished molding that he wants to use to frame the two pictures. Each strip is 36 inches long.

Assuming there is no wastage or overlap of molding, what is the minimum length of molding, in inches, Enrique still requires to frame both the pictures? Show your work and explain your reasoning in complete sentences.

Answer 1

since the frames are similar and the large frame as dimensions 45.5 / 13 = 3.5 times dimensions of smaller one, the length of larger frame is 15 * 3.5 = 52.5 inches

Answer 2

Thank you sooo much

Answer 3

o and one more
The coordinates of the vertices of two rectangles, Rectangle A'B'C'D' and Rectangle P'Q'R'S' are given below.

Rectangle A'B'C'D' – A(-4, 4), B(2, 4), C(2, 0), D(-4, 0)
Rectangle P'Q'R'S' – P(-8, 8), Q(4, 8), R(4, 0), S(-8, 0)

Jake scaled both the rectangles about their centers to create two congruent rectangles A′B′C′D′ and P′Q′R′S′.

By which factor did he most likely scale Rectangle A'B'C'D' and Rectangle P'Q'R'S'?

Rectangle A'B'C'D' by 1 by 2 and Rectangle P'Q'R'S' by 3 by 4 to create congruent rectangles of dimensions 2 x 3 units

Rectangle A'B'C'D' by 3 and Rectangle P'Q'R'S' by 2 to create congruent rectangles of dimensions 3 x 2 units

Rectangle A'B'C'D' by 1 and 1 by 2 and Rectangle P'Q'R'S' by 3 by 4 to create congruent rectangles of dimensions 9 x 6 units

Rectangle A'B'C'D' by 2 by 3 and Rectangle P'Q'R'S' by 3 and 1 by 3 to create congruent rectangle of dimensions 9 x 6 units

Answer 4

total perimeter of two frames is 2(52.5) + 2(45.5) + 2(13) + 2(15) which is the length of border required

Answer 5

hmm this one is a bit tricky - let me try some sketching..

Answer 6

ok, take your time :D

Answer 7

i'm a bit confused what do you mean by scaling by 1 by 2?

Answer 8

1 1/2

Answer 9

oh right

Answer 10

sorry guy - i must go but not clear about how to do this

Answer 11

its cool
