professor190 [17]

13 cm  long is PQ in  parallelogram .

What does parallelogram mean in a nutshell?

  • A parallelogram is a geometric shape with parallel sides that exists in two dimensions.
  • The pair of parallel sides in this sort of polygon with four sides, also known as a quadrilateral, are of equal length.
  • In a parallelogram, the sum of the adjacent angles is 180 degrees.

Perimeter of ∥gm = - 40 cm

 2(PQ+ PS) = - 40

  2 ( PQ + 7 ) = 40

        PQ + 7 = 20

           PQ = 20 - 7

           PQ = 13 cm

It cost $0.25 to use a dryer at a laundromat for 15 minutes. The expression
konstantin123 [22]

\Large\boxed{\tt Answer:~2 ~dollars}

\tt Step-by-step~explanation:

See how many times 15 can go into 120.

\tt \frac{120}{15} =8

If 15 • 8 is 120, then the cost would have to multiply by 8.

\tt 0.25*8= 2

It costs $2.00 to use the dryer for 120 minutes.

We can also use the equation to help. We plug in 120 for m and solve.

\tt 0.25(20)=30\\30 \div 15 = 2

We still end up with the same result: $2.00 for 120 minutes.

MiddPerf3. Alberto puts 3 kinds of fish in his fish tank: zebra danios, fancyguppies, and catfish. Half of Alberto's fish are ze
iris [78.8K]
That is true. Let's say there are 100 fish. If half the fish are zebra danios then there are 50 zebra danios fish. If there are 50 fish left, and there are 2 times as many catfish as there are fancy guppies, then 33.33 of them are catfish and 16.66 of them are fancy guppies. Since one third of 100 is 33.33, then 1/3 of the fish are catfish.
