To say that two or more angles are equal, we draw a little arc. If there are two arcs then it means that the angle with also two arcs marked is equal in measure, and so on
--> so:
∠A ≅ ∠Y
∠B ≅ ∠Z
∠C ≅ ∠X
To say that two more sides are equal, we draw a little tic mark. If there are two tics then it means that the sides with also two tics marked are equal in length, and so on.
--> so:
AB ≅ YZ
AC ≅ YX
BC ≅ ZX
And thus ΔACB ≅ ΔYXZ <-- we got this by matching corresponding angles of equal length
Hope it helps!

Answers
Answer:
N + B + D = 90 sum of ages is 90 (I)
B = 2 D B is twice as old as D
N + 3 D = 90 using above equations
(N + 10) + 3 D = 100 add 10 to both sides
B + 3 D = 100 Brian is 10 yrs older than Nigel
2 D + 3 D = 100 Brian is twice the age of Dean
5 D = 100
D = 20 Dean's age
Brian = 2 D = 40 Brian's age
90 - 60 = 30 = Nigel's age
Check:
N + 10 = B = 30 + 10 = 40 = Brian's age

Lincoln wants to sort 18 plums into bags so that each bag contains the
same number of plums.
He wants to end up with more than one bag of plums, and he wants each
bag to contain more than one plum.
Work out all the possibilities for the number of plums he could put into each
bag.
Answers
Work your way up from least to greatest with different possibilities.
Since there has to be more than one bag, and more than one plum in each bag, we can skip to have two bags.
1st solution: 2 bags with 9 plums in each bag.
Now we can try with 3 bags.
2nd solution: 3 bags with 6 plums in each bag.
4 can not be spread out evenly without there being halves of plums and things like that, neither can 5, so we can try with 6 bags.
3rd solution: 6 bags with 3 plums in each bag.
7 can not be spread out evenly without there being halves of plums and things like that, neither can 8, so lets try with 9 bags.
4th solution: 9 bags with 2 plums in each bag.
I think these are all the solutions, so I hope you understand and get the right answer!

state the slope and y-intercept of the graph of 9-x=2y
please explain how you got your answer. Thank you.
Answers
Answer:
slope: -1/2
y-int: 9/2
Step-by-step explanation:
rearrange 9-x=2y into slope-intercept form: y=mx+b (m being slope and b is y-intercept)
2y = -x + 9
divide both sides by 2 to isolate the y and get:
y = -x/2 + 9/2
m (slope) = -(1)/2
b (y-int) = 9/2
Erin is studying the area and population of different states. A. What is the difference in total area of Alaska and Connecticut? Express your answer in scientific notation. Show your work or explain your answer. B. What is the difference in total population of California and Alaska? Express your answer in scientific notation. Show your work or explain your answer.
Answers
Answer:
A. Total area of Alaska is considerable larger than total area of Connecticut.
B. Population of California is considerably larger that population of Alaska.
Step-by-step explanation:
A. What is the difference in total area of Alaska and Connecticut?
According to the US government, total areas of Alaska and Connecticut are 663,268 square miles ([tex]6.633\times 10^{5}[/tex] square miles) and 5,567 square miles ([tex]5.567\times 10^{3}[/tex] square miles), respectively.
The difference between both quantities is:
[tex]x = 6.633\times 10^{5}\,mi^{2}-5.567\times 10^{3}\,mi^{2}[/tex]
[tex]x = 6.577\times 10^{5}\,mi^{2}[/tex]
Which means that total area of Alaska is considerable larger than total area of Connecticut.
B. What is the difference in total population of California and Alaska?
According to the US government, total populations of California and Alaska are 39,512,223 people ([tex]3.951\times 10^{7}[/tex] people) and 710,249 people ([tex]7.103\times 10^{5}[/tex] people), respectively.
The difference between both quantities is:
[tex]x = 3.951\times 10^{7}\,people - 7.103\times 10^{5}\,people[/tex]
[tex]x = 3.880\times 10^{7}\,people[/tex]
Which means that population of California is considerably larger that population of Alaska.
Below.Does it matter the order in which the store applies the discount? In other words, is 70% off and then 20% off equal to 20% off and then 70% off? Give your answer and an explanation below. Make sure to show calculations to support your answer
Answers
Answer:
No it does not matter in which order the store applies the discount.
Step-by-step explanation:
Suppose we have the cost price = $ 100
Then 70 % off means 70% of 100= 70 $ discount
And the remaining $ 30 is again given a discount of 20 % . That would be 20 % of $ 30= $ 6 discount giving the discounted price of $ 24.
Now if we apply the discount of 20 % first that would give $ 80 discounted price and again applying 70 % to $ 80 would give $ 56 discount and a discounted price of $ 80 - $ 56= $ 24
Hence the order in which the discount is applied does not matter.

Because when you multiply 500 by 4 you start with the first 0. 4x0 is 0, now you move on to the second 0. 4x0 is 0, so that one is 0 too. Now you multiply the 5. 5x4 is 20. You put the 20 first, followed by the two 0s, And you get 2,000.

In a café there are 5 different sandwiches, 4 different desserts and 6 different drinks. Two of the desserts are sugar-free and three of the drinks are sugar-free. A meal combination is selected at random work out the probability that both dessert and drink are sugar free
Answers
Answer:
the probability that both dessert and drink are sugar free = ¼
Step-by-step explanation:
We are told that there are 5 different sandwiches, 4 different desserts and 6 different drinks.
Now, since Two of the four desserts are sugar free, then the probability that the dessert chosen is sugar free is;
P(desert sugar free) = ½
Now, three of the the 6 drinks are sugar free, then the probability that the drink chosen is sugar free is;
P(drink sugar free) = 3/6 = ½
Thus, the probability that both dessert and drink are sugar free is;
P(both sugar free) = ½ × ½ = ¼

Now suppose that x1,y1 , x2,y2 , , xn,yn are the vertices of a polygon (with positive orientation). The area of the polygon is A 1 2 C xdy ydx 1 2 x1y2 x2y1 x2y3 x3y2 xny1 x1yn . The problem asks us to find the area of the pentagon with vertices 0,0 , 2,1 , 1,3 , 0,2 , and 1,1 .
Step-by-step explanation:
The area of the given triangle JKL is 16 units square.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.
Given vertices form a triangle in the coordinate plane ;
Base = 3 + 5 = 8 units
Height = 9 - 5 = 4 units.
Since the area of a triangle is given as (1/2) × base × height.
So,
Area = (1/2) × 8 × 4 = 16 unit square.
Hence "The area of the given triangle JKL is 16 units square".

Answer:

Step-by-step explanation:
The sum of all of the angles inside of a triangle is 180 degrees. That means we know that:
[tex](x+26)+(x+14)+(4x-10)=180[/tex]
We can then combine like terms:
[tex]6x+30=180[/tex]
We want to get 6x alone, so we can subtract 30 from both sides:
[tex]6x=150[/tex]
Then we want to get x alone, so we can divide both sides by 6:
[tex]x=25[/tex]
Now we know that x is 25.
