Answer:
125%
Step-by-step explanation:
x --> 9/4 x.
x and x cancels out so we have to find out what percent 9/4 is. 9/4= 2 1/4 = 225%.
since we first started from 100%, 225%-100%=125% Hope this helped :)

What type of angle is shown?
Answer:
B. Obtuse angle
Step-by-step explanation:
Remember that a right angle is 90 degrees and would be like the edge of a square or rectangle going completely vertical. An obtuse angle is larger than 90 degrees so the vertex or point where both lines connect would have both lines farther apart. An acute angle is smaller than a 90-degree angle and is closer to touching the lines (a tip for remembering acute angles could be "a-cute angle" or a smaller cute angle). Hope this helps!

Answer:
C (Lake Depth Answer)
Step-by-step explanation:
Here we want to find the math that ends up with 0.
The stock starts with 12$, but loses 16$.
That's -4$ total, not 0.
The ion starts with 19 protons, and 18 electrons. Protons are postive charges, electrons are negative.
This leaves us with 1 proton, not 0.
The lake depth increases by 6 inches, but evaporates 6.
This leaves us back where we started, with 0.
Ahmed spends 25$, but earns 30$.
This leaves us with $5, not 0.
A solution has a pH of 10.3. When a solid is dissolved in the solution, the pH changes to 9.6. What can be inferred from this observation? (2 points)
Answer:
We see that the original material was a base, after adding the other material into the base it reduces its basicity.
So we can infer that the substance added was an acid as if we add bases it will increase the basicity.

A peacock walks 6 feet in 15 seconds how many feet can a peacock walk in 98 seconds?
Answer:
[tex]Distance = 39.2[/tex]
Step-by-step explanation:
Given
[tex]Distance = 6ft;\\ Time = 15seconds[/tex]
Required
Determine the distance covered in 98 seconds
To solve this, the following assumption must be made:
The peacock walks at a constant speedSo, first we calculate the speed
[tex]Speed = \frac{Distance}{Time}[/tex]
Substitute 6 for Distance and 15 for Time
[tex]Speed = \frac{6}{15}[/tex]
[tex]Speed = 0.40[/tex]
Next, is to calculate the required distance
[tex]Speed = \frac{Distance}{Time}[/tex]
In this case:
[tex]Speed = 0.40[/tex] because it is constant and
[tex]Time = 98[/tex]
The expression becomes:
[tex]0.40 = \frac{Distance}{98}[/tex]
Make Distance the subject:
[tex]Distance = 0.40 * 98[/tex]
[tex]Distance = 39.2[/tex]
The peacock will walk 39.2 feet in 98 seconds

The solution is Option A.
The value of the equation is P = -2 - 2i
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as z
Now , the value of z is
z = ( 1 - i )
Now , calculate the value of z³ is
z³ = ( 1 - i )³
z³ = 1³ - i³ - 3 ( 1 )²i + 3 ( i )² 1
On simplifying the equation , we get
z³ = 1 + i - 3 - 3i
z³ = -2 - 2i
Therefore , the value of z³ is -2 - 2i
The point on the graph is A
Hence , the value of the equation is -2 - 2i

Step-by-step explanation:
a hotel with 75 rooms has 45 for doubles and 30 singles. singles can be booked in any room, but reservations for two or more people must be booked in double rooms. what inequalities represents this situation?
Answer:
y = 75 - x
Step-by-step explanation:
From the question, we are given variables, and then we can see that
when x = 75 then y = 0
when x = 30 then y = 45
Finding the difference, we have
slope(m) = (45 - 0) / (30 - 75)
slope(m) = 45 / -45
slope(m) = -1
Next, we use the calculated m, to find b, using the formula
y = mx + b
0 = -1 * 75 + b
0 = -75 + b
b = 75
And finally, to get the needed equation, we say that
so y = mX+c
So that
y = -1 * x + 75
y = -x + 75
or y = 75 - x
Lee drank 1 2/3 quarts water Monday. He drank 2/5 water Tuesday. How amny quarts did he drink today?
Answer:
Lee drank 31/15 qt. of water (2 1/15 qt. as a mixed number, or approximately 20.07 qt. as a decimal).
Step-by-step explanation:
To add and subtract fractions, a least common denominator needs to be found. But first, to make it easier, mixed numbers should be replaced with improper fractions. So, Lee drank 5/3 qt. of water.
Now to find the LCD (least common denominator), the denominators of each fraction should be multiplied by 1, then 2, then 3, etc until a product of one fraction is the same as that of another (as shown):
For 2/5, the denominator is 5, so 5*1 = 5, 5*2 = 10, 5*3 = 15...
For 5/3, the denominator is 3, so 3*1 = 3, 3*2 = 6, 3*3 = 9, 3*3 = 4, 3*5 = 15...
15 is the LCD, since both denominators can be multiplied by a whole number for a product of 15.
Now, each fraction is multiplied by 1, by multiplying each fractions numerators and denominators by the number found previously that causes the denominator to equal 15:
For 2/5, 5*3 = 15, so both 2 and 5 are multiplied by 3
2* 3 = 6, 5 * 3 = 15, so 2/5 = 6/15
For 5/3, 3*5 = 15, so both 5 and 3 are multiplied by 5
5* 5 = 25, 3 * 5 = 15, so 5/3 = 25/15
Now these fractions can easily be added or subtracted by performing these operations on their numerators. Sonia drank 6/15 qt. more than Lee, so she drank 6/15 + 25/15 qt. of water, or 31/15 qt.

To make x the subject of the formula. Subtract a from both x.
[tex] a + x - a = 3 - a [/tex]
