Answer:
The height = 8 miles.
Step-by-step explanation:
Area of a trapezoid = h(a + b)/2 where h=the height and a and b are the 2 bases.
So we have:
21.2 = h(4 + 1.3)/2
5.3 h / 2 = 21.2
5.3h = 42.4
h = 42.4 / 5.3
h = 8.

I believe the answers in the blank should be 4
Step-by-step explanation:
Answer:
4.) Cost of cordless phone = $55
cost of each additional handset = $25
Therefore, the overall cost of the cordless phone, including the 3 extra handsets is:
$55 + 3($25) = $55 + $75 = $130
5.) Given the function, f(<em>d </em>) = .20<em>d</em> + 14, where:
f(d) = global temperature (in Celsius)
d = number of decades
To evaluate the value of <em>f </em>(<em>d </em>) at f(10), you'll have to substitute the value of <em>d </em>= 10 as <u>input</u> into the function:
f(10) = .20(10) + 14
f(10) = 2 + 14
f(10) = 16
6.) Value of f(10):
<em>In 10 decades, the predicted global temperature will be </em><em><u>16°</u></em><em> Celsius.</em>
7.) The correct answer is B. The global temperature f(d) depends on the number of decades, <em>d</em>.
<u>Explanation</u>: the independent variable is <em>d </em>→ it is the <u>input</u> of the function. The output primarily depends on the given value of input.
8.) Given the function, f(<em>t </em>) = 0.2<em>t</em>
where<em> t </em>= represents number of days elapsed since the planting of the seed.
Evaluate f(40):
f(40) = 0.2(40)
f(40) = 8
-
Context of f(40): The value of the function, f(40) = 8 represents the 8 centimeter height of the habanero plant after 40 days of planting its seeds.

Answer: 24 yards, choice D</h3>
There are 4 sides to this figure (trapezoid). The left slanted side and the right most vertical side, combined with the top and bottom horizontal sides, will get us the perimeter.
left slanted side = 5 yards
right most vertical side = 4 yards (see note below)
bottom side = 9 yards
top side = 6 yards
Add up the four sides mentioned: 5+4+9+6 = 9+15 = 24
note: the rectangle has opposite sides that are the same length. While the right most side isn't labeled, it is the same length as the left side of the rectangle, so both are 4 yards long.
Another thing I should probably mention is that we do not add in the interior 4 yard side. The perimeter is only the outer or exterior sides we care about. Think of it like we're trying to fence around some property lot and we don't want to subdivide the property up. Finding the perimeter will help us find the amount of fencing needed to surround the property.
