Answer:
x = -62.5
Step-by-step explanation:
y = kx
-4 = k(25)
k = -4/25
y = (-4/25)x
10 = (-4/25)x
x = 10 × 25/-4
x = -62.5
The area of a trapezoid is basically the average width times the altitude, or as a formula:
Area = h ·
b 1 + b 2
2
where
b1, b2 are the lengths of each base
h is the altitude (height)
Recall that the bases are the two parallel sides of the trapezoid. The altitude (or height) of a trapezoid is the perpendicular distance between the two bases.
In the applet above, click on "freeze dimensions". As you drag any vertex, you will see that the trapezoid redraws itself keeping the height and bases constant. Notice how the area does not change in the displayed formula. The area depends only on the height and base lengths, so as you can see, there are many trapezoids with a given set of dimensions which all have the same area.
Answer:
-5/8, -0.62, -0.615
Step-by-step explanation:
For -5/8, dividing -5 by 8 will result in -0.63, that's why it's the least (the farthest negative number from 0).
Next is -0.62
Since -0.615 isn't rounded up to the nearest hundredths, it is the greatest because it's closest to 0.
This is an unusual question. Not clear what you're looking for here.
I'd suggest that "14 quarter inches" be simplified as follows:
14 quarter inches 1 inch
------------------------- * ----------------------- = 14/4 inches = 3/2 inches = 3.5 inches
1 4 quarter inches
