Answer: 60

suppose: the width of a rectangle is x (x > 0)

⇒ The length of a rectangle is 4x

because the area of the rectangle is 144 ft

=> 4x.x = 144

⇔ x² = 144/4 = 36

⇒ x = 6

with x = 6 ⇒ The length of a rectangle is 4.6 = 24

the perimeter of the rectangle is (6 + 24).2 = 60

Triangles MOP and MNQ are similar. Find x.

konstantin123 [22]

Corresponding sides in the triangles MOP and MNQ are

MO and MN,

OP and NQ,

PM and QM.

Ratios of the corresponding sides for similar triangles should be the same.

MQ/MP =MN/MO

MQ/(MQ+QP) = MN/(MN+NO)

5/(5+x) = 6/(6+18/5)

5*(6+18/5)=6(5+x)

30+18 = 30 +6x

18=6x

A cube is numbered 1 through 6. If the cube is rolled twice, how many of the possible outcomes will have two even numbers? 3 9 1

mixer [17]

So 3/6 of the numbers on a cube are even. It will be rolled twice so you multiply 3/6 by 3/6 and get 9/36. This means 9 of the 36 possible outcomes will have 2 even numbers. It could be 2 and 2, 2 and 4, 2 and 6, and so on.
