what is x ?
what is y ?
Answer:
x = 100º
y = 100º
Step-by-step explanation:
180º = 80º+y
180º-80º = 80º-80º+y
100º = y
x and y are equal so x is also 100º

i need help plz ill give brainliest
Answer:
its either between D or C but i would pick D because the line looks like it dosen't pass through orgin (0,0).
Step-by-step explanation:
To determine whether x and y have a proportional relationship, see if the line through these points passes through the origin (0, 0). The points are on a line that passes through the origin. So, x and y have a proportional relationship.

Use the side lengths of triangle DEF and the fact that the triangles are similar to find the measure of angle E and type your answer below. (Note: Do NOT include a unit label in your answer.)
Answer:
Angle E = 65 degrees
Step-by-step explanation:
Since triangle DEF is similar to triangle BAC, angle E = angle A = 180 degrees - angle B - angle C = 180 degrees - 90 degrees - 25 degrees = 65 degrees

How do you divide a mixed number into a whole number
Answer:
Rules for division with a mixed number and a whole numberThe mixed number is converted into an improper fraction and the whole number is written as a fraction with denominator 1.
2.Division of the fractions is converted into a multiplication operation by multiplying the improper fraction with the reciprocal of the whole number.
3.The resulting fraction, if required, is written as a mixed number in simplest form.I WILL GIVE YOU EXAMPLES AND LET ME JUST HOPE YOU GET IT ;)Example1: Divide. Write your answer as a mixed number in simplest form. 213÷7 Solution Step 1: First, we write the mixed number 213 as an improper fraction 213=(2×3+1)3=73; 7=71 Step 2: The division is converted into multiplication as follows 213÷7=73÷71=73×17 Step 3: Multiplying numerators and denominators 73×17=(7×1)(3×7)=721 Step 4: 721 can be simplified and written as follows 721=13 Step 5: So, 213÷7=13example2: Divide. Write your answer as a mixed number in simplest form. 5÷134 Solution Step 1: First, we write the mixed number 134 as an improper fraction 134=(1×4+3)4=74; 5=51 Step 2: 5÷134=51÷74=51×47 Step 3: Multiplying numerators and denominators 51×47=(5×4)(1×7)=207 Step 4: 207 can be written as a mixed number as follows 207=267 Step 5: So, 5÷134=267OK HOPE THIS HELPS YOU :')PLEASE MARK ME BRILLIANT :3 THANK YOU -
Answer:First step: Write the whole number and the mixed number as improper fractions.

What is the domain:
What is the range:
Answer:
Domain: [-4,4]
Range: [-4,6]
Step-by-step explanation:
To domain pertains to the x-coordinates, while the range pertains to the y-coordinates.
Looking at the graph, we can see that the farthest point to the left is (-4,3) and the farthest point to the right is (4,6). Now, we know that the domain is [-4,4].
Looking at the graph, we can see the highest point is (4,6) and the lowest point is (0,-4). Now, we know the range is [-4,6].
Now, we know that the domain is [-4,4] and the range is [-4,6].

An average swimming pool contains 19200 gallons of water. The pool needs drained at the end of the summer. Water drains from the pool at the rate of 12 gallons per
Which equation can be used to find the volume, V, of the water in the pool t minutes after draining begins?
A- V = 12t - 19200
B- V= 19200- 12/60t
C- V= 12/60t- 19200
D= V= 19200- 12t
PLEASE HELP ASAP
PLEASE EXPLAIN HOW YOU GOT THE ANSWER
Answer:
The answer is
D. V= 19200- 12t
Step-by-step explanation:
in this problem, we already know that the pool contains 19200 gallons of water
and the pool is draining at 12 gallons per minutes, hence the volume is decreasing at that rate
Therefore for t minutes it will decrease by 12t
hence the volume after t minutes will be
V= 19200-12t

For Judy's birthday, her friends gave her a gift card. She went to the clothing store and bought a total of $178.25 worth of clothing. Judy used all of the money on the gift card to pay for part of the total. She paid the remaining $71.30 with cash. Which percentage best describes the part of the total Judy paid for with the gift card?
Answer:
60%
Step-by-step explanation:
Firstly, we want to solve for the amount on the gift card
the total cost is $178.25
the cash payment is $71.30
then the value of the gift card is
=$178.25- $71.30
=$106.95
Therefore the percentage of the gift card to the total pay is
=(106.95/178.25)*100
=0.6*100
=60%
What are number properties
Answer:
Below
Step-by-step explanation:
There are four basic properties of numbers: commutative, associative, distributive, and identity.
Communitive:
The commutative property states that the numbers on which we operate can be moved or swapped from their position without making any difference to the answer. The property holds for Addition and Multiplication, but not for subtraction and division.
Associative:
This property states that when three or more numbers are added (or multiplied), the sum (or the product) is the same regardless of the grouping of the addends (or the multiplicands). Grouping means the use of parentheses or brackets to group numbers. Associative property involves 3 or more numbers.
Distributive:
To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
Idenity:
The identity property of 1 says that any number multiplied by 1 keeps its identity. In other words, any number multiplied by 1 stays the same. The reason the number stays the same is because multiplying by 1 means we have 1 copy of the number.
These are just very few answers that I have found from google because it would be rather hard for me to explain it in my point of view, therefore if this should or maybe the number properties you are thinking of.
Answer:
commutative, associative, distributive, and identity.
Step-by-step explanation:
commutative = a + b = b + a; numbers can be added in any order and you will still get the same answer.
associative = (a + b) + c = a + (b + c) ;states that you can add or multiply regardless of how the numbers are grouped. By 'grouped' we mean 'how you use parenthesis'.
distributive: a (b + c) = a(b) + a(c); tells us how to solve expressions in the form of a(b + c).
identity: a + 0 = a; a - 0 = a; 0 has no value, so adding or subtracting numbers to 0 will just equal the number
A figure is located entirely in the third quadrant. If it is reflected over the y-axis, what will the signs of the coordinates be?
Answer:
Step-by-step explanation:
Hello friend!!!
The signs of the coordinates will be ( - , - )
This is because it is located in the third quadrant and the coordinates of any point on the third quadrant are ( - , - )
Hope this helps
plz mark as brainliest!!!!!!!
The signs of the coordinates should be ( - , - )
Signing of the coordinates:Since we know that there are 4 quadrants. In 1st quadrant, the sign is (+,+). In the 2nd quadrant, the sign is (-,+). The 3rd quadrant, the sign is (-,-), And, the fourth quadrant, the sign is (+,-),
So based on this, the above sign should be considered.
