Letter B is a function because all the x values are different. Letter C is a function also because even though the number 4 repeats, it is in the y value and not the x so as long as the x value’s are different, it is a function. Letter A is not a function because there are 2 of the same x values.

Express 1500ml as a percentage of 7.5 litres?
aniked [119]
First of all change <span>milliliters</span> to litres.

1500 ml = 1,5 l

Now, 
you know that 7,5 l = 100% (the whole amound)
and you are asking how much is: 1,5 l of the whole, so you got:

7,5 = 100%
1,5 = x%

7,5 x = 150
x = 150 / 7,5
x = 20%

Answer: 1500 ml is a 20% of the 7,5 litres.

the figure below shows andrews plan for a deck. Explain how to use triangles and rectangles to determine the area of the deck.
ELEN [110]

To find the area of the deck, we need to calculate the area of triangle and rectangles

Lets find the area of triangle A

Area of triangle = \frac{1}{2} * base * height

base = 9 and height =10

So area of triangle A = \frac{1}{2} * 9 * 10= 45

Area of rectangle = Base * height

Base of rectangle B = 9ft

Height of rectangle B = 12ft

Area of rectangle B = 9*12 = 108 square feet

Base of rectangle C = 24ft

Height of rectangle C = 22ft

Area of rectangle C = 24 * 22 =528 square feet

Area of the deck = Area of A + area of B + area of C

= 45 + 108 + 528

= 681 square feet
