Answer:

27.5 units squared

Step-by-step explanation:

Assuming the question is to find the area, the answer is 27.5(unit)^2.

I've given you the answer, but I'm also going to give you an explanation in case you decide that you want to learn how to do it.

This is a trapezium.

To find the area of a trapezium, the first step is to add A and B (the top and bottom) and then half it. In this case, it would be (4+7)/2 = 5.5.

The second and last step is to multiply that product (1/2(a+b) or 5.5 in this case) by the vertical height (5 in this case).

Examine the table shown below. Enter the slope of the line represented in the table.​

Answers

Answer:

Step-by-step explanation:

Well you see the y is always 12 so it just stays like that. Then you see the x goes up by 4 every time so its 4/12. Or simplify it.

I think the slope would be 0 since its completely horizantal and a zero slope. The formula in intercept form would also be y=x+12, in case you needed it.

Find the slope of the line. (2, 1.5) (-4, -3)

Answers

Answer:

3/4

Step-by-step explanation:

The way to find slope is by using the slope formula (y1 - y2)/(x1-x2) where you have two points (x1, y1) and (x2, y2). Next, substitute these points into the equation and you would get (-3 - 1.5)/(-4-2), which is -4.5/-6. -4.5/-6 = 3/4, so the slope is 3/4.

Answers

Answer:

This quadrilateral has  2 pairs of parallel sides. Therefore, this quadrilateral is a  parallelogram  

===========================================

Explanation:

The arrow markers on the segments tell us which sides are parallel to one another. The single arrow segments are one parallel pair, while the double arrow segments are the other parallel pair.

By definition, a parallelogram has two pairs of opposite sides that are parallel. If only one pair of opposite sides were parallel, then we'd be dealing with a trapezoid. A square is special type of parallelogram in which all four sides are the same length, and all four angles are the same measure (all four angles are 90 degrees).

Answer:

2 pairs of parallel sides, parallelogram.

For the function f(x) = 3 - 1.2x, find f(-2), f(2), f(6), and f(8).

Answers

Answer:

Don't copy the answer just yet

Step-by-step explanation:

When you're working with functions, all you need to do is to replace the "x" with the number in the parantheses.

Here, instead of "x" you need to put -2, then 2 and so on.

P.s. BE CAREFUL AT SIGNS! - * - = +

f(-2) = 3 - 1.2 * (-2)

= 3 + 2.4

= 5.4

f(2) = 3 - 1.2 * 2

=3 - 2.4

=0.6

and so on. Good luck solving this further and happy learning!  

A newspaper article reports the results of an election between two candidates. The article says that Smith received 10% of the votes and that Murphy received 1 5 of the votes. A reader writes in to complain that the article cannot be accurate. What reason might the reader have to say this?

If all the votes were for Smith or Murphy, then 10% plus ?% should equal ?%, but actually equals ?%.

Answers

If Murphy received 1 out of every 5 vote, then he received 1/5•100%=20% of the votes. If there where two candidates, then the percentage of their votes together must equal 100%, but if Murphy received 20% and Smith received 10%, then 20%+10%=30%, so the article can’t be accurate.
