Classify each pair of angles as complementary, supplementary, or neither.
Drag and drop the choices into the boxes to correctly complete the table. Each pair of angles may belong to more than one category.
complementary supplementary neither
Answer:
neither; neither; supplementary
Step-by-step explanation:
Two angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees.
First picture: 32° + 48° = 80°
80° < 90° and 80° < 180°
Therefore they are neither
Second picture: 101° + 77° = 178°
178° > 90° and 178° < 180°
Therefore they are neither
Third picture: 107° + 73° = 180°
180° < 90° but 180° = 180°
Therefore they are supplementary
neither neither and supplementery cus i smrt

The ratio of dogs to cats in a pet store is 4 : 34:3 . The ratio of cats to fish in the same pet store is 2 : 92:9. If there are 24 dogs in the pet store, how many fish are there?
Answer: In the pet store, there are 81 fish.
Step-by-step explanation:
We know that:
The ratio of dogs to cats is 4:3
(this means that for every 4 dogs, there are 3 cats)
The ratio of cats to fish is 2:9
(this means that for every 2 cats, there are 9 fish).
Now, we know that there are a total of 24 dogs in the pet store.
Remembering that for each 4 dogs we have 3 cats, we first need to see how many times we have 4 dogs in a total of 24 dogs, this is:
24/4 = 6
So we have 6 times 4 dogs, then we will have 6 times 3 cats, this is a total of:
6*3 cats = 18 cats.
And now we know that for every 2 cats we have 9 fish.
Then we need to see how many times we have 2 cats in a total of 18 cats, this is:
18/2 = 9.
And for each one of these 9 groups, we will have 9 fish, then the total number of fish is:
9*9 = 81 fish
In the pet store, there are 81 fish.

Answer:
5 - x=90°
6- angle c= 75°
7- angle a = 90°
Answer:
c = 75
Step-by-step explanation:
All triangles add up to 180. Add the two angles which you have, and then subtract that from 180. that will be your third angle value.

Answer:
ummmm what did he sayyyyyyyyy
Step-by-step explanation:
A function is given below. f ( x ) = 3 x 2 − 5 x What is the value of f ( − 4 ) ?
Answer:
[tex]f(-4)=68[/tex]
Step-by-step explanation:
We are given the function:
[tex]f(x) = 3x^2 - 5 x[/tex]
And we want to find f(-4).
So, we will substitute every x for -4. This yields:
[tex]f(-4)=3(-4)^2-5(-4)[/tex]
Evaluate:
[tex]f(-4)=3(16)-(-20)=48+20=68[/tex]
So, f(-4) = 68.

Point C is the midpoint of ⎯⎯⎯⎯⎯⎯⎯⎯ A B ¯ , point D is the midpoint of ⎯⎯⎯⎯⎯⎯⎯⎯ A C ¯ , point E is the midpoint of ⎯⎯⎯⎯⎯⎯⎯⎯⎯ A D ¯ , and point F is the midpoint of ⎯⎯⎯⎯⎯⎯⎯⎯⎯ A E ¯ . If =3 A F = 3 , what is the number of units in the length of ⎯⎯⎯⎯⎯⎯⎯⎯ A B ¯ ?
The number of units in the length of AB is 56 units by using the concept of midpoint and the whole length is twice the length of half.
please i need help with this i dont understand it
Answer:
1. No
2. Right triangle
3. No
4. Right triangle
Step-by-step explanation:
A, B = two smallest sides
C = hypotenuse, largest side
Pythagorean theorem. If A^2 + B^2 = C^2, then you have a right triangle.
Which point is a solution to the linear inequality y<
-1/2x+2
O (2, 3)
O (2,1)
O (3,-2)
O (-1,3)
Answer: Choice C. (3,-2)
A diagram is shown below.
===============================================
Explanation:
There are two approaches we can take. Since we're given a list of choices, we can plug each of the coordinates one at a time into the inequality. If we get a true statement, then it is a solution.
For choice A, we have x = 2 and y = 3 paired up together. Plugging them into the given inequality leads to...
y < (-1/2)*x + 2
3 < (-1/2)*2 + 2
3 < -1 + 2
3 < 1
This is false because 3 is not smaller than 1. So (2,3) is not a solution. You should find that choice B leads to a similar situation because
y < (-1/2)*x + 2
1 < (-1/2)*2 + 2
1 < -1+2
1 < 1
and 1 cannot be smaller than itself. So (2,1) isn't a solution either.
However, choice C is the answer since,
y < (-1/2)*x + 2
-2 < (-1/2)*3 + 2
-2 < -1.5 + 2
-2 < 0.5
This is true because -2 is to the left of 0.5 on the number line. So that's why (3,-2) is a solution.
For choice D, you should find that (-1,3) doesn't make the inequality true.
-----------------------------------------------------------
An alternative approach:
As a visual way to solve this problem, we can graph the given inequality by following these steps
Draw a dashed line through the points (0,2) and (4,0). This forms the graph of y = (-1/2)x + 2Shade below the dashed lineWe make the boundary line dashed because points on the boundary do not count as solution points. This is due to the lack of "or equal to" in the inequality sign. We shade below the boundary line because of the "less than".
As the diagram below indicates, the blue region consists of every (x,y) solution point that makes y < (-1/2)*x + 2 true.
The diagram also shows that only point C is in that blue region, making it a solution point. Point B on the boundary does not count as a solution. You can think of the dashed line as an electric fence you can only get closer to, but can't touch, in terms of determining a solution point.
So effectively, this is a quick and easy way to find solutions if you have a graphing calculator or online graphing tools (such as Desmos or GeoGebra).
tickets to a waterpark cost $53 per person. write an expression to show the total cost of tickets for p people (pre algebra)
Answer:
$53p
Step-by-step explanation:
If tickets to a waterpark cost $53 per person, this can be expressed as;
$53 = 1 person
To find the cost of p people, we will write;
$x = p people
Divide both expressions
53/x = 1/p
x * 1 = 53 * p
x = 53p
Hence the cost of p people is $53p
What type of solutions to quadratic equations can be solved by factoring and using the zero product property?
Answer:
The Zero Product Property states that if ab = 0, then either a = 0 or b = 0, or both a and b are 0. When the product of factors equals zero, one or more of the factors must also equal zero. Once the polynomial is factored, set each factor equal to zero and solve them separately.

lynn has one red shirt one blue shirt and one yellow shirt to choose from. She also has one blue and one yellow necklace to choose from for work today are these values dependent or independent
I would say the answer is depending. the reason I choose this answer because she chose a random shirt, which she probably chose a necklace that would look best with the shirt she had randomly had choosen.
