Answer:
Julie would have 800 pens
Step-by-step explanation:
You would convert the fraction to a decimal which would be 0.8 and then you would multiply that by 1000 which would be 800. So Julie would have 800 pens.
4/5 = 8/10 = 0.8
0.8 * 1000 = 800
Base is always the number on the bottom. Height is always the line in the middle of the triangle unless the triangle is a right angle (90 degree triangle) and if it is, the number on the side is the height. Here's a picture of it:

All fractions contain integers and rational numbers

Answer:
20t-28
Step-by-step explanation:
expand the bracket
Using an indirect proof:
Assume that the figure is a trapezoid.
All trapezoids are quadrilaterals.
All quadrilaterals' interior angles add up to 360° because any n-gon's interior angles add up to 180(n-2)°.
We are given that the trapezoid has three right angles.
All right angles are 90°, thus these right angles have a total measure of 270°.
We can conclude fourth angle must be 90°.
If it has four right angles, it is a rectangle.
Rectangles have two sets of parallel sides.
However, trapezoids have exactly one set of parallel sides.
Alas, our figure cannot be a trapezoid.
