To find the number that 37.5% of it equals 6, set up an equivalent fractions equation, cross-multiply, and solve for the unknown number. In this case, 37.5% of 16 is 6.
Explanation:The question pertains to finding a certain number when given a percentage of that number. Here, we're asked to find the number of which '37.5% is 6'. We can solve this through simple arithmetic and the use of equivalent fractions. An important rule to remember is that 'percentage' literally means 'per 100', so 37.5% can be written as the fraction 37.5/100.
To find the unknown number (let's call it X), you can set up the equation 37.5/100 = 6/x, where 'x' is the number we're trying to find. Then you cross-multiply to solve for 'x': 37.5 * X = 6 * 100. Simplifying this, X = (6 * 100) / 37.5. Calculating that out gives X = 16. Therefore, 37.5% of 16 is 6.

hi! can anyone help me pls?
Answer:
Option B, -4 and 4
Step-by-step explanation:
Step 1: Subtract 15 from both sides
y^2 - 1 - 15 = 15 - 15
y^2 - 16 = 0
Step 2: Factor
y^2 - 16
(y + 4)(y - 4)
Step 3: Find the solutions
y + 4 - 4 = 0 - 4 and y - 4 + 4 = 0 + 4
y = -4 and y = 4
Answer: Option B, -4 and 4
Answer:
-4 and 4
Step-by-step explanation:
All you need to do is solve for y
[tex]y^{2} - 1 = 15\\[/tex] (plus 1 to both sides)
[tex]y^{2} = 16[/tex] (take square root of 16)
[tex]y = \sqrt{16}[/tex]
[tex]y = +-4[/tex] (whenever you to the root of a perfect square you want the positive and negative root)
To double check if your answer is right: plug in -4 and +4 in as y and see if it equals 15
1. [tex](4)^{2} - 1 =15[/tex]
[tex]16-1 = 15\\15= 15[/tex]
(positive 4 checks out)
2. [tex](-4)^{2} - 1 = 15[/tex]
[tex]16 - 1 = 15\\15 = 15[/tex]
( negative 4 checks out)
the cube and rectangular prism have the same base area and height. how can you use this information to determine the volume of the pyramid?
The given pyramid's volume is 40 cubic units.
Step-by-step explanation:
Step 1:
It is given that base areas of the pyramid and the prism are the same. The height is also equal.
The rectangular prism's height is 15 units so as per the given question, the height of the pyramid is also 15 units.
Step 2:
The volume of this pyramid is obtained by multiplying [tex]\frac{1}{3}[/tex] with the product of the pyramid's length, width, and height.
For the given pyramid, length = 2 units, width = 4 units and the height = 15 units.
The pyramid's volume [tex]= \frac{1}{3} (length)(width)(height)[/tex] = [tex]\frac{1}{3} (2)(4)(15) = \frac{1}{3} (120)[/tex] = 40 cubic units.
So the volume of the given pyramid is 40 cubic units.

For f(x) = 2x+1 and g(x) = x+14, find (gof)(x).
Answer: OPTION B
Step-by-step explanation:
You can observe that the exercise provides you two Linear functions.
The first Linear function is the function f(x). This is:
[tex]f(x) = 2x+1[/tex]
And the other Linear function is the function g(x):
[tex]g(x) = x+14[/tex]
In order to find [tex](gof)(x)[/tex], you need to follow these steps shown below:
Step 1:
You must substitute the function f(x) into the function g(x); this means that the function f(x) will be in the place of the variable "x" of the function g(x); as you can observe below:
[tex](gof)(x) = (2x+1)+14[/tex]
Step 2:
Finally you must combine the like terms (You can notice that the like terms are 1 and 14; then you must add them). Therefore, you get that [tex](gof)(x)[/tex] is:
[tex](gof)(x) = 2x+1+14\\\\(gof)(x) = 2x+15[/tex]

How should the decimal point in 52.48 be moved to determine the product 52.48×10 to the power of 5?
Enter your answers in the boxes to correctly complete this statement.
The decimal point should be moved ___ places to the right because there are ___ zeros in 10 to the power of 5.
Decimal point moved 5 places to the right, since 10⁵ has 5 zeros in it.
Step-by-step explanation:
52.48 is multiplied by 10 to the power of 5, that is 100, 000, we will get ,
[tex]52.48 \times 10^{5}=5248000.00[/tex]
When 52.48 is multiplied by 100,000, we will get 5248 followed by 5 zeros, 524800000.
Now we have to count the decimal point from left to right, so we will get 5248000.00, zeros after the decimal point has no value.
The decimal point should be moved _5__ places to the right because there are _5__ zeros in 10 to the power of 5.
a picture frame holds a 4-in. by 6-in. photograph. the frame adds a border x inches wide around the three sides of the photo. on the fourth side the frame forms a border that is 3x - 0.5 in. wide. the combined area of the photograph and the frame is 80.5 in^2. write a quadratic equation for the combined area. Then use the quadratic equation formula to find x
Answer:
1. The quadratic equation is 3x² +17.5x - 58.5 = 0
2. The values of x are 2.38 and -8.21, but we only take 2.38 for our problem.
3. The dimensions of the combined area are approximately 6.38 inches and 12.64 inches.
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Photograph dimensions = 4 inches * 6 inches
Frame dimensions = x inches * 3x - 0.5 inches
Area of the combined area of the photograph and the frame = 80.5 inches²
2. Write a quadratic equation for the combined area. Then use the quadratic equation formula to find x.
One side of the combined area of the photograph and the frame = 4 + x inches
Second side of the combined area of the photograph and the frame = 6 + 3x - 0.5 inches
Now, we can write the quadratic equation this way:
Combined area of the photograph and the frame = One side * Second side, replacing with the values we know:
80.5 = (4 + x) * (6 + 3x - 0.5)
80.5 = (4 + x) * (5.5 + 3x)
80.5 = 22 + 5.5x + 12x + 3x²
3x² +17.5x - 58.5 = 0
Using the quadratic formula, where, a = 3, b = 17.5 and c = - 58.5, we have:
x = (-b +/- √b² - 4ac)/2a
x = (-17.5 +/- √17.5² - 4 * 3 * -58.5) 2 * 3
x = (-17.5 +/- √306.25 + 702)/6
x = (-17.5 +/- √1,008.25)/6
x = (-17.5 +/- 31.75)/6
x₁ = 14.25/6 = 2.38
x₂ = -49.25/6 = -8.21
We took the value of x₁ because x₂ is negative and we can't have a negative value for the length or the width, therefore:
80.5 = (4 + x) * (5.5 + 3x)
Replacing x, we have:
80.5 = (4 + 2.38) * (5.5 + 3 * 2.38)
80.5 = 6.38 * 12.64
80.5 ≅ 6.38 * 12.64

Have to find out what the angle x is respond ASAP pls
Answer: Angle x equals 19 degrees
Step-by-step explanation: We have two polygons, one with five sides and the other with eight sides. The question states that the pentagon has exactly one line of symmetry which means the line that runs down from point D to line AB divides the shape into exactly two equal sides. Hence angle A measures the same size as angle B (in the pentagon).
First step is to calculate the angles in the pentagon. The sum of angles in a polygon is given as
(n - 2) x 180 {where n is the number of sides}
= 3 x 180
= 540
This means the total angles in the pentagon can be expressed as
A + B + 84 + 112 + 112 = 540
A + B + 308 = 540
Subtract 308 from both sides of the equation
A + B = 232
Since we have earlier determined that angle A measures the same size as angle B, we simply divide 232 into two equal sides, so 232/2 = 116
Having determined angle A as 116 degrees, we can now compute the value of angle A in the octagon ABFGHIJK. Since the figure is a regular octagon, that means all the angles are of equal measurement. So, the sum of interior angles is given as
(n - 2) x 180 {where n is the number of sides}
= 6 x 180
= 1080
If the total sum of the interior angles equals 1080, then each angle becomes
1080/8
= 135 degrees.
That means angle A in the octagon measures 135, while in the pentagon it measures 116. The size of angle x is simply the difference between both values which is
x = 135 - 116
x = 19 degrees

What is Algebra?Algebra is the part of mathematics that helps represent problems or situations in the form of mathematical expressions.
Given:
Cullen is 10 years younger than Ada.
The product of their ages 2 years ago was 39.
let the age of ada be x
Cullen's age = x- 10
22 years ago there age will be
Ada = x-22

Now, the product of their age is 39
(x-2)(x-12)=39
x²-12x-2x + 24=39
x² -14x + 24=39
x² - 14x -15 = 0
x² -15x + x- 15=0
x(x-15) + 1(x-15)=0
(x-15)(x-1)=0
x= 15 or -1.

In a class of 50 students,27 are athletes 9 are musicians and 6 of the musicians are athletes . If one student is randomly selected from the class , find the probability of choosing an athlete or a musician
Answer: 0.6
Step-by-step explanation:
Total population of class = 50
There are 27 athletes, and 9 musicians However, 6 of the musicians are also athletes.
Therefore, totals for athletes and musicians are:
27 + 9 -6 = 30
Thus, the probability of choosing an athlete or a musician is 30/50= 0.6
We could also use the formula:
P(A or M) = P(A) + P(M) - P(A and M)
P(A or M)=27/50+9/50-6/50
P(A or M)=30/50=0.6

Nine out of twelve members of a jury are over 35 years old. What percent of the jury is not over 35?
Answer:
75% are so 15%
Step-by-step explanation:
To determine the percentage of the jury not over 35 years old, divide the number of jurors not over 35 by the total number of jurors (3/12) and then multiply by 100, resulting in 25 percent.
Explanation:If nine out of twelve jurors are over 35, then three out of twelve jurors are not over 35. To find out what percentage of the jury is not over 35, we use the following calculation:
Divide the number of jurors who are not over 35 by the total number of jurors. So we get 3/12.To convert this fraction into a percentage, multiply by 100. So we get (3/12) × 100.Perform the multiplication: 3 × 100 = 300, then divide by 12: 300 / 12 = 25.Therefore, 25 percent of the jury is not over 35 years old.
