Answer:
1.2 km
Step-by-step explanation:
The first thing that we should go over is the formula for the area of a trapezoid.
Recall that it is
From this image, we have the following information
Now, we can plug this information into our formula and then solve for h.
Another method that can be employed is to use the pythagorean theorem.
A trapezoid can be be broken into a rectangle and two triangles.
If we look at the difference in the sizes of the bases, the bottom base is 1 km larger. This means that the base of each triangle would be 0.5 km long.
As we have two side lengths of the triangle, we can now use the Pythagorean theorem to find the third side, which is h.
Answer:
2.25or21/4
Step-by-step explanation:
hope it helps
Lindsey has 25 inches long ribbons now.
Further explanation:
Simple addition and multiplication has to be used to solve this question.
Given
Ribbon Lindsey already has= 10 inches
Number of pieces she bought inches = 3
Length of each ribbon piece = 5 inches
So,
As she already had 10 inches, now she has
Lindsey has 25 inches long ribbons now.

Answer:
D. An input is the value that determines another based on the relation or function rule, usually the x-values in a set of ordered pairs on a tale or graph.
Step-by-step explanation:
For any relation (given ordered pairs), there are x - values and y-values, also called inputs and outputs. For every input, there is an output. For example, given the function rule:
y = 2x + 1
If x = 1, y = 3
If x = 2, y = 5
and, so on..
So, the output (y) is determined by the input (x) and is usually the x-values.
