. CDEF is a trapezium
guajiro [1.7K]

9514 1404 393

Answer:

  24 cm²

Step-by-step explanation:

To find the area of the trapezium, we must know the length CD. That means we must know the length BC. Fortunately, the perimeter of ABCF is given, so we have ...

  P = 2(AB +BC)

  BC = (P/2) -AB = (20 cm)/2 - 6 cm = 4 cm

Then CD is ...

  CD = BD -BC = 9 cm -4 cm = 5 cm

The area of the trapezium is given by the formula ...

  A = (1/2)(b1 +b2)h

  A = (1/2)(5 cm + 3 cm)(6 cm) = 24 cm²

The area of trapezium CDEF is 24 cm².

Find the slope of the line passing through the points<br> (-6,-5) and (4,4)
marshall27 [118]

Answer:

\frac{9}{10}

Step-by-step explanation:

The slope formula is  m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Here, x_{1} is -6, x_{2} is 4, y_{1} is -5, and y_{2} is 4.

m=\frac{4+5}{4+6}

m=\frac{9}{10}

So, the slope of the line passing through the points (-6,-5) and (4,4) is \frac{9}{10}.

a national park has two options: a $50 pass for all admissions during the year, or a $4 entrance fee each time you enter. Write
frutty [35]
<span>With the variable "y" being used to represent the total cost of going to the park for a year, the first equation would read "y = 50" since it is a one-time, flat cost. The second equation would be "y = 4x", with "x" being used to represent the number of times the person visited the park during the year multiplied by the $4 cost per visit.</span>
