Answer:
25 yards
Step-by-step explanation:
A parallelogram is a quadrilateral (a four sided object) with parallel sides
Some of the characteristics of a parallelogram includes :
- Opposite sides and angles are congruent .
- Opposite angels are congruent (D = B).
- Consecutive angles are supplementary (A + D = 180°).
- The diagonals bisect each other
Area of a parallelogram = base x height
Area = 525
base = 21 yards
height = ?
525 = 21 x height
divide both sides of the equation by 21 to find the value of the height
525 / 21 = height
height = 25 yards
Answer: Choice A
four and eighty three hundredths with the three repeating
In other words, 4.8333...
====================================================
Explanation:
Use long division to find that 5/6 = 0.8333... where the 3s go on forever. The steps for the long division are shown in the diagram below. You can use a calculator to confirm.
Therefore, 4 & 5/6 = 4 + 5/6 = 4 + 0.8333... = 4.8333...
Since the 3 repeats forever, we can use a horizontal bar to place over the 3 like this 
Steve has 340 colored pencils , that was pretty easy
Answer:
1) A
2) B
Step-by-step explanation:
For this problem we use exponential growth formulas
if the population increases when t increases
If the population decreases when t increases
Where and is the population as a function of time,
is the initial population, r is the growth rate, t is the time in years.
1) In this situation we have that
, the growth is 2.4%, then
and
and the equation is:

-------- Option A)
2) In this situation we have that
, the decrease is 1.7%, then
and
and the equation is:

-------- Option B)
The answer is Pythagorean
The Pythagorean theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
