Answer: A. 9

Step-by-step explanation:

Given: The red line and the green line are perpendicular to each other.

The slope of green line = $\dfrac{-1}{9}$

We know that the product of slopes of two perpendicular line is -1.

Let m be the slope of red line ], then we have

$\dfrac{-1}{9}\times m=-1\\\\\Rightarrow\ m=\dfrac{9}{1}=9$

Hence, the slope of the red line = 9.

The opposite reciprocal of -1/9 is 9
So the answer is A

How do you know 3 ÷180 is smaller than 1

Diano4ka-milaya [45]

Answer:

Because 180 is bigger than 3 and your trying to divide 180 into 3. Which isn't gonna come out an even number. 0.01666666666 is a lot smaller than 3.

Find the slope of the line that is parallel to the line y = 2x + 5

Ugo [173]

Answer:

Step-by-step explanation:

parallel lines have same slope.

y = 2x + 5

y = mx + b

m is the slope

b is y-intercept

Find the area of the shape shown below.

vlabodo [156]

Answer:

6 $cm^{2}$ (assuming the units is in centimetres)

Step-by-step explanation:

Hi, hope this helps!

Method 1:

Calculate this shape as a trapezium. This is a trapezium because it has one pair of parallel sides. The way to calculate the area of a trapezium is this:

- Half the sum of the parallel sides

- Multiply the perpendicular height between them

In this case, 4 and 2 are parallel, so we add them together (4 + 2 = 6) then we divide by two (6 ÷ 2 = 3). Then we multiply our answer by the perpendicular length between the two parallel sides (assuming the side on the left is at a right-angle, 3 x 2 = 6).

Method 2:

Calculate this shape as a rectangle + a triangle. If you split the shape so the pointy bit on the right becomes a triangle and the left becomes a square, you can calculate the area without knowing the formula for calculating a trapezium (see above ^).

- Area of the square / rectangle = length x width = 2 x 2 = 4

- Area of the triangle = 1/2 x length x width = 2 x 2 x 1/2 = 4 x 1/2 = 4 ÷ 2 = 2

Then we add the two areas together (4 + 2 = 6).

I hope this helped and I wasn't waffling on :)
