30-60-90 triangles
hypotenuse = 2(short leg)
short leg = 1/2(hypotenuse)
long leg = short leg(√3)
short leg = long leg/√3
45-45-90 triangles

Jayden and Carson are selling T-shirts and sweatshirts for a fundraiser. Jayden sells 9 T-shirts and 3 sweatshirts for $420. Carson sells 1 T-shirt and 6 sweatshirts for $296.
Write a system of equations (without solving it) representing the price of a T-shirt, t, and the price of a sweatshirt, s
Answer:
9t + 3s = 420
t + 6s = 296
s =44; t = 32
Step-by-step explanation:
Let
Price of a T-shirt = t
Price of a sweatshirt = s
Jayden:
9t + 3s = 420
Carson:
t + 6s = 296
9t + 3s = 420 (1)
t + 6s = 296 (2)
From (2)
t =296 - 6s
Substitute t =296 - 6s into (1)
9t + 3s = 420 (1)
9(296 - 6s) + 3s = 420
2664 - 54s + 3s = 420
2,664 - 51s = 420
-51s = 420 - 2,664
-51s = -2,244
s = 44
Substitute s = 44 into (2)
t + 6s = 296
t + 6(44) = 296
t + 264 = 296
t = 296 - 264
t = 32
s =44; t = 32
Carl's age is three more than two times Lindsay's age. Carl is 39 years old. How old is Lindsay? Let L=Lindsay's age in years. Write the equation that represents this problem. Explain how you used math to write the equation.
Answer:

A ball is thrown upward from a height of 15 feet with an initial upward velocity of 5 feet per second. Use the formula b(t)= -16t2 + 5t + 15 to find the time it takes for the ball to reach the maximum height of the ball. Round to the nearest tenth.
Answer:
Time taken by the ball to reach the maximum height = 5/32 seconds
Step-by-step explanation:
To find the time at which maximum height is reached , we will differentiate the given equation with respect to t
[tex]\frac{db_{(t)}}{dt} = -32t + 5 = 0\\t = \frac{5}{32} \\[/tex]
Substituting this value of t in formula of b(t), we get
[tex]-16 * (\frac{5}{32})^2 + 5 * \frac{5}{32} + 15 \\= 15.390[/tex]

Jerry Asked His Friends How long it took them to get ready In the Morning?
What is the Difference Between the length of time it took the friend who spent the most time getting ready and the length of time took the friend who spent the least time getting ready?
A: 6\8 Hr
B:7\8 Hr
C:7\0 Hr
D:6\0Hr
Answer:
The answer is A.
Step-by-step explanation:
First, you look at the longest time which is 7/8. Next, you look at the shortest time which is 1/8. You take 1/8 from 7/8 which is 6/8 which is A.

answer this question and show work or have an explanation.
Answer:
70
Step-by-step explanation: Triangle angle sum theorem states the interior angles of a triangle sum to 180 degrees. We know one angle is 40 degrees and the two remaining angles are equal in measure.
Since angle J and angle L are equal in measure we can substitute 2x for angles J and L into the equation.
40 + 2x = 180. Subtract 40 from both sides.
2x = 140. Divide both sides by 2.
X = 70

You found yourself lost in a forest. Give an account of your experience and how you found your way out
Answer:
Step-by-step explanation:
This actually happened to me. I was walking out of a national forest and came up to a stream that I had not crossed. I got my bearings confused and realized I was lost. I knew that if I went Northwest it would be about a 30 mile hike out in heavy woods, with obvious other streams to cross. In the Southeast direction, it would only be about 5 miles.
The sun was out but mostly overhead and no help with directions.
I couldn't wait until the sun went farther West to get my directions. It was a warm Winter day but I wasn't dressed to be there after dark when the temperature fell, even if I did go in the correct direction.
I stuck a stick in the ground and made a mark in the dirt at the end of it's shadow. I sat down for about 15 minutes, then made a new mark in the dirt at the end of the sticks shadow again. I drew a line in the dirt to connect the two marks. This line ran close to the East/West direction, the first mark being the West direction.
I made it out about 5 PM just as the sun was disappearing through the trees.

Answer:
polygons
Step-by-step explanation:
this is a hexagon so the sum of interior angles is 720. so add all of those angles and expressions and set it equal to 720. collect like terms and solve for x
once you have x, evaluate and get the exact angle measurements.
Look at the system of equations below. Y=2x+5 y=x+6 What is the x-coordinate of the solution to the system?
Answer:
1
Step-by-step explanation:
Given the system of equations below
y=2x+5
y=x+6
Equating the right hand side of the expressions we will have;
2x+5 = x+6
Collect the like terms;
2x - x = 6 - 5
x = 1
Hence the x-coordinate of the solution to the system is 1
