Answer:

6.32

Step-by-step explanation:

There's an easy trick for this. Move the decimal point once to the left, and then multiply by 2.

31.60 turns into 3.16 (which is 10% btw)

Multiply 3.16 by 2 and you get 6.32, or 20% of 31.60. Hope this helped!

the parallel sides of a trapezium are such that the longer side is 4cm more than the shorter side of the distance between them i
saw5 [17]

Answer:

32cm and 28cm

Step-by-step explanation:

Area of a trapezium=0.5 ( sum of parallel sides ) × height

600=0.5( 4+a+a)×20

where a is the length of the shorter side

600÷0.5=(4+2a)×20

1200=(4+2a)×20

1200÷20=4+2a

60=4+2a

60-4=2a

56=2a

56÷2=a

28=a.

since the longer side is 4 cm more than th shorter side , 28 +4=32

Write the function in standard form<br><br> f(x) = -4 (x - 6)^2 + 15
amid [387]

9514 1404 393

Answer:

  f(x) = -4x^2 +48x -129

Step-by-step explanation:

It usually works well to compute the square first. That is, simplify according to the order of operations.

  f(x) = -4(x^2 -12x +36) +15

  f(x) = -4x^2 +48x -144 +15

  f(x) = -4x^2 +48x -129
