since JHG = 65, then the other two angles added together = 65. Therefore, I can just add what the two smaller angles are to equal 65. Solve for x, then plug x into one of the equations! JHI = 19, and GHI = 46

2) How many minutes after takeoff does the drone land on the ground?
minutes
Answers
Answer:
h(t) = -3(t-8)(t+4). and 8 minutes
Step-by-step explanation:
The function can be written as: h(t) = - 3(t² - 4t - 32). As per quadratic equation, after take off, the drone will land on the ground after 8 minutes.
What is a quadratic equation?A quadratic equation is an equation that contains a variable with highest degree of 2.
Given, the height of the drone t minutes after take off is modeled by
h(t) = - 3t² + 12t + 96 = - 3(t² - 4t - 32)
Therefore, the function can be written as: h(t) = - 3(t² - 4t - 32)
Therefore, we can write the equation as:
t² - 4t - 32 = 0
⇒ t²- 8t + 4t - 32 = 0
⇒ t(t - 8) + 4(t - 8) = 0
⇒ (t + 4)(t - 8) = 0
Hence, (t + 4) = 0 and (t - 8) = 0
Therefore, t = -4, 8.
As 't' can't be negative, therefore, t = 8.
Therefore, after take off, the drone will land on the ground after 8 minutes.

Two students are having a party. They want to make treat bags for their guests. They want each bag to be identical with nothing leftover. They have 36 Silly Bandz and 72 pieces of Double Bubble to put in the bags. What is the greatest number of treat bags they can make? How many of each item will be in each treat bag?
Answers
Answer:
Two students can make maximum 36 treat bags.
Number of pieces of silly Bandz in each bag [tex]=1[/tex]
Number of pieces of Double Bubble in each bag [tex]=2[/tex]
Step-by-step explanation:
Number of pieces of silly Bandz = 36
Number of pieces of Double Bubble = 72
To find greatest number of treat bags that they can make, find H.C.F. of 36 and 72
[tex]36=(2^2)(3^2)\\72=(2^3)(3^2)[/tex]
[tex]H.C.F(36,72)=36[/tex]
So,
they can make maximum 36 treat bags.
Number of pieces of silly Bandz in each bag [tex]=\frac{36}{36}=1[/tex]
Number of pieces of Double Bubble in each bag [tex]=\frac{72}{36}=2[/tex]

please explain how you got your answer thank you :)
Answers
Answer: {x,y}={6,21}
Step-by-step explanation:
// Solve equation [2] for the variable x
[2] 3x = 18
[2] x = 6
// Plug this in for variable x in equation [1]
[1] 2•(6) - y = -9
[1] - y = -21
// Solve equation [1] for the variable y
[1] y = 21
// By now we know this much :
x = 6
y = 21
We are done
Answer:
y = 2x -6. A dependent system, so all numbers on this line.
Step-by-step explanation:
2x - y = 6
-3y = -6x + 18
In order to solve a system of equations, you want to get isolate y. One equation already has done that for us, so that makes it easier.
2x - y = 6
In order to isolate y in this equation, you must simply subtract 2x from both sides, which would give us:
-y = -2x + 6
Now, you can't leave y negative. Normally you'd divide the y by its variable, but this one doesn't have a variable. so you must divide both sides by -1.
[tex]\frac{-y}{-1} =\frac{-2x+6}{-1}[/tex]
We divide both sides because what you do to one side you must do to the other. This leaves us with the equation:
y = 2x - 6
Now, for the other equation. It's simple since y is already isolated.
-3y = -6x + 18
Once again we will be dividing both sides, but this time it's by -3.
[tex]\frac{-3y}{-3} =\frac{-6x+18}{-3}[/tex]
We are dividing by -3 instead of -1 because y in this equation has a variable of -3. This would give us:
y = 2x - 6
Now, normally in order to get the answer, you must graph both of these equations, but since these equations ended up being the same, the answer is every number that appears on the line. This is called a dependent system.

Given :
A rectangle with a length of 3 x and height of x. If Kyle uses 18 feet of wood to make the frame.
To Find :
The length of the frame.
Solution :
We know, perimeter of the rectangle is given by :
[tex]P=2(l+b)\\\\P=2(3x+x)\\\\P=8x[/tex]
Now, it is given that 18 feet of wood is used.
So,
[tex]8x=18\\\\x = 2.25\ feet[/tex]
Therefore, length of frame is given by 3x = 6.75 feet.
Hence, this is the required solution.
Answer: A, 6.75
Step-by-step explanation: If the frame is 3 times the width and Kyle uses 18 feet them this the only correct option out of the other 3.

✺ Divide both sides by −3. Since −3 is negative, the inequality direction is changed:
-3 ÷ -3 = Cancels OutTurns into: [tex]\frac{-9}{-3} >5x-2[/tex]✺ Divide −9 by −3 to get 3. Since they are both negatives it turns into a positive:
-9 ÷ -3 = 3Turns into: [tex]3 > 5x - 2[/tex]✺ Swap sides so that all variable terms are on the left hand side. This changes the sign direction once more:

Step-by-step explanation:
This means the cost of the item to you is $42.49. You will pay $42.49 for a item with original price of $49.99 when discounted 15%. In this example, if you buy an item at $49.99 with 15% discount, you will pay 49.99 - 7.4985 = 42.49 dollars.
Answer:
42.49
Step-by-step explanation:
Discount = 15% of 49.99
= 0.15 * 49.99
= 7.4985
Cost after discount = 49. 99 - 7.4985
= 42.4915
