The angles of each side of a hexagon is 120 degrees.
The sum of interior angles in a shape is (n-2) * 180.
So,
(6-2) * 180 = 4 * 180 = 720 degrees
This is the total degrees of the hexagon.
Dividing the total degrees by 6 angles gives us 120 degrees for each angle.
Angle AEF = angle FED - angle AED.
Angle FED = 120 degrees
Angle AED = 90 degrees
120 - 90 = 30 degrees

Tara found a pair of jeans that were regularly priced at $35. She has a coupon for 15% off. What is the price of the jeans after applying the coupon?
$20
$7
$29.75
$33.50
Answers
35-5.25=29.75
Answer:
The price is $29.75
Step-by-step explanation:
Because it is 15 percent off, that means that the jeans are priced at 100%-15%=85%. To convert a percent to a decimal, move the decimal two places to the left. This gives us .85. Multiply 35 by .85 and you will get 29.75. Hope this helps!
If tu = 6 units, what must be true? su ut = rt rt tu = rs rs su = ru tu us = rs
Answers
In the provided figure of line segment RS, the statement which is true is su + ut = rt. Option A is correct.
What is the length of line segment?Length of a line segment is the distance of both the ends of it.
The length of the line segment TU is 6 units.
[tex]TU=6\rm\; units[/tex]
In the figure attached below, the length of line segment RT is 12 and RS is 24. Thus, the value of RS is double than the value of RT.
[tex]RT=2RS\\RS=\dfrac{RT}{2}[/tex]
RS is the total length of the segment, which is equal to the length of RT and ST.
[tex]RT+ST=24\\12+(SU+UT)=24\\(SU+UT)=24-12\\SU+UT=12[/tex]
12 is the length of RT. Thus,
[tex]SU+UT=RT[/tex]
Hence, in the provided figure of line segment RS, the statement which is true is su + ut = rt. Option A is correct.

Step-by-step explanation:
First write out the equation which is (5x - 3x²) - (5x - 2)(10x + 7x²). Then distribute 5x - 3x² to -(50x² + 35x³ - 20x - 14x²).

You throw a football and it leaves your hand of 5 feet. Its initial velocity is 20 feet per second. What is the maximum height the ball will reach? Also, how long will it take the ball to hit the ground? (Equation used: h(t)= -16t^2 + v0t + h0.)
Please show work
Answers
Answer:
The max height is 11.25 feet and the ball will take 1.464 seconds to hit the ground
Step-by-step explanation:
The quickest way to solve this equation is by using the equation that you gave, which is h(t)= -16t^2 + v0t + h0. This equation models the trajectory of the football, which means that at the equation's vertex, we can model what the height of the ball is. Along with that, by finding the positive root of where h(t) = 0, we can find how long it will take for the ball to hit the ground.
First, lets find h0 and v(0)
h0 is the initial height of the ball. So we know that the ball leaves your hand of 5 feet, so h0 = 5. Similarly, the initial velocity is 20 ft/sec, so v0 = 20.
Plugging 5 in for h0 and 20 for v0, we get h(t) = -16t^2 + 20t + 5.
Second, find max height.
To find the vertex of a parabola, use -b/2a to find the time, and plug that into h(t) to get the height.
b=20
a=-16
t = -b/2a = -20/2(-16) = .625 seconds
h(.625) = 11.25 feet
The max height is 11.25 feet
Third, find how long.
To find this, we need to find the t-intercepts of the equation.
set h(t) = 0
-16t^2 + 20t + 5 = 0
Use quadratic formula to find t
t = (- 20 ± [tex]\sqrt{20^{2} - 4(-16)(5)}[/tex])/2(-16)
t = {1.464}, -.214
The ball will take 1.464 seconds to hit the ground.

A large box of crackers weighs 20 oz. If James needs 3 pounds of crackers for a party, how many boxes of crackers should he buy?
Answers
each box is 200z, that means each box is a little over 1 pound. (1.25 pounds to be exact). So, we know that he needs to buy 3 boxes of crackers. This is because 20×3=60 ounces which is 3.75 pounds. Meaning, 3 boxes is the correct answer since we can't cut a box in half.

Leo buys pasta for 12 people,
(a)
Each person eats 100 grams of pasta.
One packet has 500 grams of pasta.
How many packets must Leo buy?
Answers
Answer:
3
Step-by-step explanation:
If each packet has 500 grams, and each person eats 100 grams, then one packet will feed five people (500/100=5). Since he will be buying pasta for 12 people, he will need to buy three packets, because 3*500=1500 grams. While there is some extra, buying only two packets would result in not enough pasta.

Albert has a rectangular print that is 1 foot in length and 8 inches in width. He wants to reduce the dimensions of the print proportionally so that the new print has a width of 3 inches. What should be the length of the new print?
Answers
Answer:
2.6 inches
Step-by-step explanation:
As shown in the title if length is x,
x * 1/x = 8/3 * x
8 * 1 = 3x
x = 8/3 in
= 2.6 in
The new length of the rectangular print will be 2.68 feet.
What is a rectangle?A rectangle is a geometrical figure in which opposite sides are equal.
The angle between any two consecutive sides will be 90 degrees.
Area of rectangle = length × width.
Perimeter of rectangle = 2( length + width).
Given a rectangular print with dimensions,
Length = 1 foot = 12 inches
Width = 8 inches.
Area = 12(8) = 96 square inches
Now,
The area of the new print should be the same
So,
96 = Length × 3
Length = 32 inches = 2.67 feet.
Hence "The new length of the rectangular print will be 2.68 feet".

O C. F(52)
D. F(99)

Answers
F(51)
===========================================================
Explanation:
The very large numbers are likely put there as a distraction. They aren't needed. Adding any two adjacent Fibonacci numbers will lead to the next term in the sequence. This is simply based on how the special number sequence is defined or set up.
This means F(49)+F(50) = F(51) i.e. adding the 49th and 50th terms will generate the 51st term.
In general,
F(n) + F(n+1) = F(n+2)
where n is a positive integer.
