how to convert 90% to a decimal point
Answer:
0.90
Step-by-step explanation:
Just like a decimal to a percentage number, you must multiply by 100. By converting a percentage number to a decimal point, you must divide it by 100. Which means, the decimal must move 2 times.
For example,
0.90 x 100 = 90%
This is decimal to percentage number, but in this case it is percentage to decimal.
90%.
Since the number ended at 0, put the decimal there and move it 2 times to get to your decimal point.
.90 = 0.90

The composite function f(f(x)) has a solution of - (1 - x)/x
Evaluating the composite functionFrom the question, we have the following parameters that can be used in our computation:
f(x) = 1/1 - x
To calculate f(f(x)), we replace the occurence of x in the function f(x) = 1/1 - x with f(x)
Using the above as a guide, we have the following:
f(f(x)) = 1/1 - f(x)
Substitute the known values in the above equation, so, we have the following representation
f(f(x)) = 1/(1 - 1/(1 - x))
Evaluate
f(f(x)) = - (1 - x)/x
Hence, the solution is f(f(x)) = - (1 - x)/x

A. 2.1%
B. 21%
C. 3%
The percentage of saline solution in brand B is 3%. Then the correct option is C.
Let x be the percent of saline solution in brand B.
Since Danielle combined brands A and B to create a total of 18 gallons of 8% saline solution, we know that the total volume of saline solution in the combination is 18% of 6 gallons + x% of (18 - 6) gallons.
Thus, we can set up the equation:
0.18(6) + 0.01x(18 - 6) = 0.08(18)
Simplifying and solving for x, we get:
1.08 + 0.12x = 1.44
0.12x = 0.36
x = 3

Comparing the equations of the two lines, we can see that they have the same slope (3/2). Therefore, the lines are parallel.
To determine whether these two lines are parallel or perpendicular, we can convert Line 2 into slope-intercept form (y = mx + b):
2y = 3x + 5
y = (3/2)x + 5/2
Comparing this equation to the equation of Line 1 (y = x + 7), we see that the slopes (coefficients of x) of the two lines are not equal, nor are they negative reciprocals of each other. Therefore, the lines are neither parallel nor perpendicular.
Line 1 and Line 3:
To determine whether these two lines are parallel or perpendicular, we can convert Line 3 into slope-intercept form (y = mx + b):
6x - 4y = 4
-4y = -6x + 4
y = (3/2)x - 1
Comparing this equation to the equation of Line 1 (y = x + 7), we see that the slopes of the two lines are not equal, nor are they negative reciprocals of each other. Therefore, the lines are neither parallel nor perpendicular.
Line 2 and Line 3:
To determine whether these two lines are parallel or perpendicular, we can convert Line 2 into slope-intercept form (y = mx + b):

y = (3/2)x + 5/2
Next, we can rearrange Line 3 into the slope-intercept form:
6x - 4y = 4
-4y = -6x + 4
y = (3/2)x - 1
Comparing the equations of the two lines, we can see that they have the same slope (3/2). Therefore, the lines are parallel.

Emma has half of her investments in stock paying a 10%
dividend and the other half in a stock paying 14% interest. If her total annual interest is $600, how much does she have invested?
Emma has $5,000 total invested.
Let's call the total amount Emma has invested "x".
Emma has half of her investments in stock paying a 10% dividend, so that portion of her investment earns 0.10(x/2) = 0.05x in annual interest.
The other half of her investments are in a stock paying 14% interest, so that portion of her investment earns 0.14(x/2) = 0.07x in annual interest.
The total annual interest Emma earns is $600, so we can set up the following equation:
0.05x + 0.07x = 600
0.12x = 600
x = 5000

Answer: B
Step-by-step explanation:
First, you have to know that a straight line is equal to 180 degrees. They gave you 115 degrees in part of a line, so the other part or the angle not given must be equal to 65 degrees. Another thing is that a triangle has 180 degrees. 65+80 degrees is equal to 145 degrees, leaving angle 1 to be equal to 35 degrees. Another thing to know is that reflective angles have the same measurement. If the original angle was equal to 65 after subtraction 115 from 180, we know that the second triangle's angle would also be equal to 65. 65+86 is 150, and 180-150 is 30. Thus, the answer is B.

Mrs. Cowley purchases $32,000 worth of stock on her broker's advice and pays her broker a 0.75% broker fee. She is forced to sell it when it falls to $25,100 two years later, and uses a discount broker who charges $17 per trade. Compute her net loss after the broker fees are taken out.
Answer: $6,320.25
Step-by-step explanation:
Mrs. Cowley's broker fee is calculated by multiplying the purchase price by the broker fee percentage: $32,000 x 0.0075 = $240. Her total cost for the purchase is then $32,000 + $240 = $32,240. When she sells the stock for $25,100, she incurs another fee of $17 for using the discount broker. To calculate her net loss, we subtract her total cost from her selling price and subtract the two broker fees: $25,100 - $32,240 - $17 - $17 = -$6,320.25, which is rounded to $6,320.25 as a net loss.
Two cyclists leave towns 130 kilometers apart at the same time and travel toward each other. One cyclist travels 5 km/h faster than the other.If they meet in 2 hours, what is the rate of each cyclist?
Answer:
Faster cyclist = 37.5km/h
Slower cyclist = 32.5km/h
Step-by-step explanation:
Let's call the rate of the slower cyclist "r" (in km/h). Then the rate of the faster cyclist is "r+5" (in km/h), since they are traveling 5 km/h faster.
We know that the two cyclists are traveling towards each other and will meet in 2 hours. We can use the formula:
distance = rate × time
Let's call the distance each cyclist travels "d". Since they are traveling towards each other, their distances will add up to the total distance between the two towns, which is 130 km. So we can write:
d + d = 130
2d = 130
d = 65
Now we can use the formula again to find the rates of the two cyclists:
For the slower cyclist:
distance = rate × time
65 = r × 2
r = 32.5 km/h
For the faster cyclist:
distance = rate × time
65 = (r+5) × 2
r+5 = 32.5 + 5 = 37.5 km/h
So the rate of the slower cyclist is 32.5 km/h, and the rate of the faster cyclist is 37.5 km/h.

For a standard normal distribution, given:
P(z < c) = 0.0234
Find c.
The value c = -2.07 for a standard normal distribution with P(z < c) = 0.0234.
To find the value of c for which P(z < c) = 0.0234 for a standard normal distribution, we can use a standard normal distribution table or a calculator with a built-in normal distribution function.
Using a standard normal distribution table, we can look up the area to the left of c and find the corresponding z-score. This z-score will be the value of c for which P(z < c) = 0.0234.
Looking up the area 0.0234 in the table, we find that the corresponding z-score is approximately -2.07.
Therefore, c = -2.07 for a standard normal distribution with P(z < c) = 0.0234.

The quadratic equation is the polynomial having the highest power of 2. If 5i and -5i are the solutions to the quadratic equation, then the quadratic equation can be written as:
(x - 5i)(x + 5i) = 0
Expanding this equation, we get:
x² - (5i)² = 0
x² - 25i² = 0
Since i² = -1, we can substitute -1 for i², giving us:

The area of the shaded region is equal to 12.5π or 39.27 square centimeters.
How to calculate the area of the shaded region?In Mathematics and Geometry, the area of a semicircle can be calculated by using this formula:
Area of semicircle, As = πr²/2
Where:
r represents the radius of a circle.
Note: Radius = diameter/2 = 20/2 = 10 centimeters.
By substituting the radius into the formula for the area of a semicircle, we have the following;
Area of semicircle = 1/2 × π × 10²
Area of semicircle = 50π square centimeters.
For the circle, we have:
Area of circle, Ac = πr²
Area of circle, Ac = π(10/2)²
Area of circle, Ac = 25π square centimeters.
Now, we can determine the area of the shaded region as follows;
Area of shaded region = (As - Ac)/2
