[tex]\frac{9.00 - 7.50}{7.50} \times 100\% = 20\% \: increase[/tex][tex] \frac{6.50 - 5.00}{5.00} \times 100\% = 30\% \: increase[/tex][tex] \frac{4.50 - 2.00}{2.00} \times 100\% = 125\% \: increase[/tex][tex] \frac{2.00 - 2.50}{2.50} \times 100\% = - 20\%[/tex]In order to get the increase or decrease, we need to get the difference of the two prices first. Then, pick a "reference year".
From the calculations, notice how I made the earlier years as my reference points. If the calculations produced positive results, therefore, it has increased. If it produced a negative results, from the reference year's price, it has decreased in price.
4x-8+3x-16+95=180 or else im so confused
Answer:
x = 17, see below for angle measures
Step-by-step explanation:
You're on the right track!
The sum of those two angles inside the triangle equal that opposite angle outside of the triangle. Therefore, you can set them equal to each other.
(4x - 8) + (3x - 16) = 95
Because you are adding the expressions, you can take away the parentheses without changing anything.
4x - 8 + 3x - 16 = 95
Now you want to combine like terms on the left side.
4x + 3x - 8 - 16 = 95
7x - 24 = 95
Combine like terms once again.
7x = 119
Divide to isolate x.
x = 119/7
x = 17
Plug this value back into each expression to find the angle measures.
∠HFG = 4x - 8
∠HFG = = 4(17) - 86
∠HFG = 68 - 8
∠HFG = 60º
∠FGH = 3x - 16
∠FGH = 3(17) - 16
∠FGH = 51 - 16
∠FGH = 35º
∠FHI = 95ª
∠FHG = 180 - 95
∠FHG = 85º

The missing side of the right angle triangle is 8.0622577483 units.
What is Pythagoras theorem?In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.
Given:
Triangle is a right angle triangle.
And the sides of a right-angled triangle are:
Base = 4 unit
Perpendicular = 7 units.
To find the length of the hypotenuse:
We apply Pythagoras theorem,
(hypotenuse)² = (base)² + (perpendicular)²
Substituting the values in the equation,
(hypotenuse)² = (4)² + (7)²
(x)² = 16 + 49
(x) = √(65)
(x) = 8.0622577483
Therefore, the value of x is 8.0622577483 units.

Which equation matches the hanger diagram?
pls help !!!
Option D is correct, 2x=5 is the equation which matches the hanger diagram.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
We need to find the equation which matches the hanger diagram.
Hanger models are a visual representation of an equation
For the hanger to remain balanced, each side has to have the same weight. Like a seesaw, a scale, or a barbell.
In the left side of hanger there 2 x's and on right side there are fives ones.
So 2x=5 is the equation which satisfies the given hanger diagram.
Hence, Option D is correct, 2x=5 is the equation which matches the hanger diagram.

You decide to invest $250 in an account that yields a return of approximately 4% each year. If you were to write an exponential equation representing the situation, what would the initial value be?
Answer:
250x.04=x
Step-by-step explanation:
250x.04 would be 10 so you get a 10 doller return each year.
You decide to invest $250 in an account that yields a return of approximately 4% each year. Then, the initial value would be 10 doller return each year.
What are exponential functions?When the expression of function is such that it involves the input to be present as exponent (power) of some constant, then such function is called exponential function.

Answer:
1) x = 12.2
3) x = 21.7
5) x = 17.9
7) x = 31.8
Step-by-step explanation:
Use Pythagorean Theorem (a^2 + b^2 = c^2 where a and b are bases and c is hypotenuse)
1) 10^2 + 7^2 = x^2
100 + 49 = x^2
149 = x^2
x = sqrt 149 which is about 12.2
3) 16^2 + x^2 = 27^2
256 + x^2 = 729
x^2 = 473
x = sqrt 473 which is about 21.7
5) 9^2 + x^2 = 20^2
(we know the other base is 9 because in an isosceles triangle, the altitude (the height) is the same as the median (which divides the base into half)
81 + x^2 = 400
x = sqrt 319 which is about 17.9
7) 16^2 + y^2 = 22^2 (y is the height of the triangle)
256 + y^2 = 484
x = sqrt 228
(sqrt 228)^2 + (44-16)^2 = x^2
228 + 784 = x^2
x^2 = sqrt 1012 which is about 31.8
