What is the answer to this question?

Serga [27]

Answer: 87.5

Step-by-step explanation:

The Area formula for a Trapezium is

depicted in the two picture below.

As seen in the picture Area equals

A+B(h) all divided by 1/2 or simplistic terms 2.

A+b

A= ---------- (h)

So we need to plug our information in

as Depicted in the picture measurement A is first top side

And B is bottom base

so h IS the height of the figure. Its the middle line in the middle of the figure.

10+15

A= ________(7)

10+15=25

25*7=175

175/2=87.5

So your answer is

Area of ABCD is 87.5

20 POINTS !!! <br><br> Find the distance between the points (3,-4) and (5, 4)

jeka57 [31]

Answer:

$d=2\sqrt{17}\approx8.2462$

Step-by-step explanation:

To find the distance between two points, use the distance formula.

The distance formula is:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2$

Let (3,-4) be x₁ and y₁ and let (5,4) be x₂ and y₂. Therefore:

$d=\sqrt{(5-3)^2+(4--4)^2$

Simplify:

$d=\sqrt{(2)^2+(8)^2$

Square:

$d=\sqrt{4+64}$

Add:

$d=\sqrt{68}$

Simplify:

$d=\sqrt{4\cdot17}=\sqrt4\cdot\sqrt{17}$

Simplify:

$d=2\sqrt{17}\approx8.2462$

C.)
Since the ideal width is 7 cm and can vary by most 0.3 cm. This means the range is 6.7 cm to 7.3 cm Absolute value means that any negative number becomes positive. l 6.7 -7 l and l 7.3 - 7 l both equal 0.3 cm
l w - 7 l </= 0.3
