She read 7 1/2 miles. You multiply 3 3/4 by 2
Answer:
The height of the taller tree is 7.5 feet.
Step-by-step explanation:
I am going to say that:
The height of the shorter tree is x.
The height of the taller tree is y.
The height of shorter tree is 3/5 of the height of the taller tree.
This means that
If the height of the shorter tree is 4 1/2 feet tall, what is the height, in feet, of the taller tree?
This means that
We want to find y.
The height of the taller tree is 7.5 feet.
Foci (focus points) of an ellipse
Two points inside an ellipse that are used in its formal definition. See Ellipse definition.
Try this Drag any orange dot. As you reshape the ellipse, note how the two focus points (F1 and F2) move.

An ellipse has two focus points. The word foci (pronounced 'foe-sigh') is the plural of 'focus'. One focus, two foci.
The foci always lie on the major (longest) axis, spaced equally each side of the center.
If the major axis and minor axis are the same length, the figure is a circle and both foci are at the center.
Reshape the ellipse above and try to create this situation.
Note how the major axis is always the longest one, so if you make the ellipse narrow,
it will be the vertical axis instead of the horizontal one.
Answer:
38 units (rounded off to the nearest unit)
Step-by-step explanation:
- Find the perimeter of the circle part, if the circle section is a 90degree slice, then it is a quarter of the full circle's circumference
- now find a quarter of this then
-
- Then find the perimeter of the whole thing by adding the side
