Answer:
x= 9
Step-by-step explanation:
<2 + 40 + 40 = 180 degree
<2 = 180 - 40 - 40
<2 = 100
m<2 = x + 109
x = 109 - <2 = 109 - 100 = 9
Explanation: A triangle has 180° and since 2 angles are 40° (Isosceles triangle) we can do: 180-40-40 which equals 100. Angle 2 equals 100 so we can plug that in to the equation of:
100= x + 109
-109 -109
-9 = x

Charlie is shopping for a jacket that he likes. The jacket, regularly priced at $200, is on sale at Clothes Are Us for $150. Jacket World is offering a 25% discount on the same jacket that regularly sells for $190 at that store. Which statements are correct for this situation?
A) Jacket World's price is $150.00
B) Jacket World has the better deal.
C) Clothes Are Us has the better deal.
D) Both stores are offering a 25% discount on the jacket.
E) The difference in the sale prices at the two stores is $7.50.
Answers
The correct options are:-
Choice B) Jacket world has the better deal.
Choice D) Both stores are offering a 25% discount on the jacket.
Choice E) The difference in sale prices at the two stores is $7.50
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
25% = 0.25
25% of $190 = 0.25*190 = 47.50
190 - 47.50 = 142.5
This indicates the price at Jacket World is $142.5 instead of $150
Therefore, choice A is false.
Choice B on the other hand is true because $142.50 at Jacket World is a lower price compared to $150 at Clothes Are Us. Jacket World has the better deal.
Because choice B was shown to be true, there's no way choice C can be true as well. Otherwise, we'd have a contradiction. So we can rule out choice C.
Let's find the percentage discount for Clothes Are Us.
The original price is $200 and its sale price is $150. So you save 200-150 = 50 dollars.
Divide that over the original price to find the discount: 50/200 = 0.25 = 25%
Therefore, Clothes Are Us has the same discount percentage as Jacket World. Both have a 25% discount. Choice D is true.

Solutions of Linear Equations
Use What You Know
You've learned how to solve linear equations and how to check your solution. In this
lesson, you'll learn that not every linear equation has just one solution. Take a look
at this problem.
Jason and his friend Amy are arguing. Jason says that a linear equation always has just one
solution. Amy says that some linear equations have more than one solution. Who's right?
Amy asked Jason to explore solutions to the following equation
2x + 1 + x = 3x - 2)+7
Use the math you already know to solve this problem.
Remember that a solution to an equation is a number that makes the equation true.
To check to see if a number is a solution to this equation, replace x with its value.
a. Is 6 a solution to the equation? Show your work
b. Is -2 a solution to the equation? Show your work. 2X

Original price: $60; Markup: 15%; Retail price:
Answers
Answer:
Retail Price = $69
Step-by-step explanation:
Original Price = $60
Markup = %15
Retail Price = $60 + (0.15 * $60)
Solve:
We can say that 60 is 100% of 60 or 1 x 60
So the equation is:
1 x 60 + 0.15 x 60 = Retail Price
1.15 x 60 = Retail Price
Retail Price = 69
-Chetan K
Answer:
Original Price is $60
But it is markup 15%
(15x60) / 100 = 9
the 15% of 60 is 9
60 + 9 = 69
Now the retail price is $69

Help..
Answers
Answer:
1/9
Step-by-step explanation:
1) simplify the expression
Group like terms: (2-5-3) + 1/t = 3
Simplify the arithmetic: -6+1/t=3
2) Isolate the t
Multiply to both sides by t: -6+1/t=3t
Expand the parentheses: -6t+1t/t=3t
Simplify the left side: -6t + 1 = 3t
3) Group all t terms on the left side of the equation
Subtract 3t from both sides: -6t+1-3t=3t-3t
Group like terms: -6t-3t+1=3t-3t
Simplify the arithmetic: -9t+1=3t-3t
Simplify the arithmetic: -9t+1=0t
Simplify the right side: -9t+1=0
4. Group all constants on the right side of the equation
Subtract 1 from both sides: -9t+1-1=0-1
Simplify the arithmetic: -9t=0-1
Simplify the arithmetic: -9t=-1
5. Isolate the t
Divide both sides by-9: -9t/-9=-1/-9
Cancel out the negatives: 9t/9=-1/-9
Simplify the fraction:t=-1/-9
Cancel out the negatives: t=1/9
A dive ring on the bottom of the pool is 10 feet below the surface of the water. Sabine dives down and brings the ring back to the surface. What integer represents the dive ring's final position with respect to the surface of the water.
Answers
The final position of the dive ring with respect to surface of water ls 0.
Representing position using integer :
10 feets below the surface = - 10
To recover the ring, then, Sabine needs to 10 feets below the surface.
The surface the water = sea level position = 0
Since, Sabine takes the ring back to the surface, then the final position of the dive ring will be the sea level.
The final position of the dive ring = 0
We know that we use negative sign in integers to show a value is decreased or dropped and positive sign to show increase or rise.
Given : A dive ring on the bottom of the pool is 10 feet below the surface of the water. Sabine dives down and brings the ring back to the surface.
i.e. Integer represents the distance Sabine dives down = -10 feet (1)
and Integer represents to come back to surface = +10 feet (2)
Now, the final position will be (combine (1) and (2)) :
-10+10=0
Thus, the integer represents the dive ring's final position with respect to the surface of the water = 0

The ratio of Jay age to Hena's age to Sally age is 4:3:6.Jay is 24 years old
(a)Find Sally's age.
(b)What is their total age?
Answers
Answer:
1. Write It Out:
Jay 4: Hena 3 : Sally 6
Jay is 24 years old.
2. Solve
So first you find 24/4 to get 6. This means Jays age was divided by 6 to get his ratio number. Showing that Hena's and Sally's is divided by 6 as well to get there ratios. Now what you need to do is mulitipy Hena and Sallys ratio by six to find there age's.
Hena: 3x6= 18 years old
Sally: 6x6= 36 years old
(Jay: 4x6= 24 years old)
Now to find there total age add them up...
18+36+24= 78
A. Sally is 36
B. 78
Answer:
Sally is 36 years old.
their total age is 78 years.
Step-by-step explanation:
[tex]4 + 3 + 6 = 13[/tex]
that's the total ratio
Jay is 24 years old and his ratio is 4
so assume the total age to be
[tex]x[/tex]
[tex]4 \div 13 \times x = 24[/tex]
[tex]4x \div 13 = 24[/tex]
[tex]4x = 24 \times 13 \div 4[/tex]
[tex]x = 78 \: total \: age[/tex]

The power, P (watts), of a car engine is proportional to the square of its speed, s (m/s).
When s=35, P=2200.
Work out the power (to 1 DP) when the speed is 40 m/s
Answers
Answer:
THE ANSWER!!!!!!!!!!
Step-by-step explanation:
The power, P (watts), of a car engine is proportional to the square of its speed, k%28m%2Fs%29; it means if you have two different powers and speeds, you will have a proportion
P%3Ak%5E2=P%5B1%5D%3Ak%5B1%5D%5E2 or
P%2Fk%5E2=P%5B1%5D%2Fk%5B1%5D%5E2
When given:
k=35, P=2200
Work out the power P%5B1%5D (to 1DP) when the speed is k%5B1%5D=40%28m%2Fs%29
so,
P=2200
k=35
k%5B1%5D=40
and you need P%5B1%5D
2200%2F35%5E2=P%5B1%5D%2F40%5E2
2200%2F1225=P%5B1%5D%2F1600
1.79592=P%5B1%5D%2F1600
1.79592%2A1600=P%5B1%5D
P%5B1%5D=2873.5 watts

Our coordinate is (-2,6)

(6, 2)
Step-by-step explanation:
Rotation rules about the origin:
90° clockwise (or 270° counterclockwise): (x, y) → (y, -x)180° clockwise (or 180° counterclockwise): (x, y) → (-x, -y)270° clockwise (or 90° counterclockwise): (x, y) → (-y, x)Therefore, to rotate (-2, 6) clockwise 90° about the origin:
⇒ (-2, 6) → (6, -(-2)) → (6, 2)
