On Monday, Maggle ran n miles. On Tuesday, she ran 90% of the number of miles that she ran on Monday. On Wednesday, she ran 50% of the
number of miles that she ran on Tuesday.
Move a symbol to the box and expressions to the blanks to create two equivalent expressions that represent the total number of miles
Maggie ran on Monday, Tuesday, and Wednesday.

Second expression:

Answer:
[tex]Total = 2.35n[/tex]
Step-by-step explanation:
Given
Monday = n
Tuesday = 90% of Monday
Wednesday = 50% of Tuesday
Required
Determine the total miles
We have:
Tuesday = 90% of Monday
Substitute n for Monday
Tuesday = 90% of n
[tex]Tuesday = 90\% * n[/tex]
Express percentage to decimal
[tex]Tuesday = 0.90 * n[/tex]
[tex]Tuesday = 0.90n[/tex]
We also have that:
Wednesday = 50% of Tuesday
Wednesday = 50% * Tuesday
Substitute 0.90n for Tuesday
[tex]Wednesday = 50\% * 0.90n[/tex]
Express percentage to decimal
[tex]Wednesday = 0.50 * 0.90n[/tex]
[tex]Wednesday = 0.45n[/tex]
The total number of miles is:
[tex]Total = Monday + Tuesday + Wednesday[/tex]
[tex]Total = n + 0.90n + 0.45n[/tex]
[tex]Total = 2.35n[/tex]

You are going to Wal-Mart to buy DVD's. The DVD'sare packaged in a box. There are thirty five DVDs in the box. You only want five. The box cost forty-five dollars. How much did you pay? How much change do you get back if you pay with fifty dollars? Explain the order of operations that was used.
Answer:
DVD sales have been on the decline for over a decade, but a slew of new streaming services and a shift in how consumers are watching movies and TV shows could be the final death knell for the technology.
The same can be said for Blu-Ray discs.
At its peak, DVD sales reached $16.3 billion and were 64% of the U.S. home video market. That was 2005. These days, DVD sales account for less than 10% of the total market, with total sales hitting $2.2 billion in 2018.
Blu-Ray discs, which have always been slightly more expensive than DVDs, launched in 2006. At most, Blu-Ray sales reached $2.37 billion in 2013, before falling to $1.8 billion in 2018. It’s likely that Blu-Ray sales fractionally impacted the decline of DVD sales, but the fact that DVD sales still outpace Blu-Ray sales shows it’s not the real culprit.
Instead, a combination of the Great Recession, a rise in customers buying on-demand and digital copies of films and the launch of streaming services is what has caused DVD sales to decline more than 86% in the last 13 years.

A penguin starts at 15 meters above sea level and ends at 7 meters below sea level. What is the change in elevation?
Answer:
22 meters
Step-by-step explanation:
If the penguin goes from 15 meters above sea level to sea level (0 meters), they traveled 15 meters in elevation.
Then they traveled another 7 meters when going 7 meters below sea level.
15 + 7 = 22

3(1.5x+9)= tell me NOW
Answer:
x = -6
Step-by-step explanation:
Simplifying
3(1.5x + 9) = 0
Reorder the terms:
3(9 + 1.5x) = 0
(9 * 3 + 1.5x * 3) = 0
(27 + 4.5x) = 0
Solving
27 + 4.5x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-27' to each side of the equation.
27 + -27 + 4.5x = 0 + -27
Combine like terms: 27 + -27 = 0
0 + 4.5x = 0 + -27
4.5x = 0 + -27
Combine like terms: 0 + -27 = -27
4.5x = -27
Divide each side by '4.5'.
x = -6
Simplifying
x = -6
Interior-Angle
Lesson 7.8
Divide the polygon into triangles. Then, multiply the number
of triangles by 180 to find the interior-angle sum for each
polygon.
Answer:
To find the sum of interior angles of a polygon, multiply the number of triangles in the polygon by 180°. The formula for calculating the sum of interior angles is ( n − 2 ) × 180 ∘ where is the number of sides. All the interior angles in a regular polygon are equal.

Find the 80th derivative of f(c)
ET
sin(2).
f(80)
Submit Question
Compute the first few derivatives to reveal a pattern:
f(x) = x sin(x)
f '(x) = x cos(x) + sin(x)
f ''(x) = (-x sin(x) + cos(x)) + cos(x) = -x sin(x) + 2 cos(x)
f '''(x) = (-x cos(x) - sin(x)) - 2 sin(x) = -x cos(x) - 3 sin(x)
f ''''(x) = (x sin(x) - cos(x)) - 3 cos(x)) = x sin(x) - 4 cos(x)
f ⁽⁵⁾(x) = (x cos(x) + sin(x)) + 4 sin(x) = x cos(x) + 5 sin(x)
f ⁽⁶⁾(x) = (-x sin(x) + cos(x)) + 5 cos(x) = -x sin(x) + 6 cos(x)
f ⁽⁷⁾(x) = (-x cos(x) - sin(x)) - 6 sin(x) = -x cos(x) - 7 sin(x)
f ⁽⁸⁾(x) = (x sin(x) - cos(x)) - 7 cos(x) = x sin(x) - 8 cos(x)
and so on.
The pattern should be clear: for some integer k,
• if n = 4k, then f ⁽ⁿ ⁾(x) = x sin(x) - n cos(x)
• if n = 4k + 1, then f ⁽ⁿ ⁾(x) = x cos(x) + n sin(x)
• if n = 4k + 2, then f ⁽ⁿ ⁾(x) = -x sin(x) + n cos(x)
• if n = 4k + 3, then f ⁽ⁿ ⁾(x) = -x cos(x) - n cos(x)
80 is a multiple of 4, so the 80th derivative falls in the first category. Then
f ⁽⁸⁰⁾(x) = x sin(x) - 80 cos(x)

Use the pythagorean Theorem to prove the three sides of the triangle are the three sides of a right triangle. Show all of your work. 2,4,2,√3
Answer:
[tex]2^{2}[/tex] + [tex](2\sqrt{3}) ^{2}[/tex] = 4 + 4 * 3 = 16 = [tex]4^{2}[/tex]
Step-by-step explanation:
The Pythagorean Theorem states that the two shorter sides of a right triangle squared and added together will equal the longest side (hypotenuse) of the right triangle squared. The longest side of this right triangle is 4, 4 squared is 16. The two shorter sides of the right triangle are 2 and [tex]2\sqrt{3}[/tex], squared individually would be 4 and 12, and added together they also equal 16. These sides are a valid input for the Pythagorean Theorem, so these three sides are the sides of a right triangle. 2 and [tex]2\sqrt{3}[/tex] being the legs of the right triangle, and 4 being the hypotenuse.
