Step-by-step explanation:
Multiplying both sides by 100 and dividing both sides by 6,
Answer:
24 % of that number is 4
Step-by-step explanation:
First solution:
If 6% of a number is 1, then 1% is 1/6 which is a repeating decimal, so we can just take it as 1/6. Then, to find 24% of that number we would have to do 1/6 x 24 which is equal to 24/6. 6 can evenly divide 24 which is 4.
Second solution:
We can see that since 24 is evenly divided by 6, to find 24%, we can multiply 1 by 4 because 6% x 4 = 24%
Therefore, 24% of that number is 4.

What is quadratic function?A quadratic function is a polynomial function of the form:
f(x) = ax^2 + bx + c,
where a, b, and c are constants and x is the independent variable. The graph of a quadratic function is a parabola, which is a symmetrical, U-shaped curve.
The set of all feasible dependent variable values based on the input or independent variable constitutes the range of a quadratic function. The direction of the parabola and the value of the y-intercept can be used to establish the range (the constant c).
In mathematics, science, and engineering, quadratic functions are used extensively. Examples include modeling motion, projectile motion, and parabolic reflectors as examples of physical phenomena. They are also utilized in optimization issues where the aim is to discover the highest or lowest value of a given function.
According to question:
The range of a quadratic function is the set of all possible values of the dependent variable, based on the input or independent variable.
From the table, it appears that the range of the function h is all real numbers less than or equal to 5. This is because, for all values of x given in the table, the corresponding value of h is less than or equal to 5. So, the correct answer is:

1/5(4x - 2.5) = 5(0.4x + 10) + 3 1/2
Answer: 7.34375
Step-by-step explanation:
Answer step bby step:
1. Isolate the variable:
1/5(4x - 2.5) = 5(0.4x + 10) + 3 1/2
5(0.4x + 10) + 3 1/2 = 1/5(4x - 2.5)
2. Multiply both sides by 5:
2(0.4x + 10) + 3 1/2 = 4x - 2.5
3. Subtract 2(0.4x + 10) from both sides:
3 1/2 = 4x - 2(0.4x + 10)
4. Subtract 3 1/2 from both sides:
0 = 4x - 2(0.4x + 10) - 3 1/2
5. Distribute the -2 to the parentheses:
0 = 4x - 0.8x - 20 - 3 1/2
6. Combine like terms:
0 = 3.2x - 23.5
7. Divide both sides by 3.2:

it is not accurate to state that one of the cross sections is a square as it will be a rectangle.
What is a square?
Having four equal sides, a square is a quadrilateral. There are numerous square-shaped objects in our immediate environment. Each square form may be recognised by its equal sides and 90° inner angles. A square is a closed form with four equal sides and interior angles that are both 90 degrees. Numerous different qualities can be found in a square.

The required area of the shaded region is 11.5 sq. units
What is area?Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.
Given is a circle with center T and radius 3 units. there is a region in the circle which is shaded, we need to find that area.
So, the shaded part is composed of a right triangle and a minor sector of the circle.
To find the area of the shaded portion, we will add the area of right triangle and a minor sector
Now, area of a triangle = 1/2 × base × height
Here, base = height = radius = 3 units
And,
Area of a sector = θ/360° × π × radius²
Where, θ is the central angle.
θ = 90°
Area of the shaded region = 1/2 × 3 × 3 + 90°/360° × 3.14 × 3²
= 9/2 + 7.065
= 11.565
Hence, the required area of the shaded region is 11.5 sq. units

Dana is attaching a shelf to a wall and needs the shelf to be parallel to the floor. How many degrees should the shelf be relative to the floor?
Answer:
The shelf should be 0 degrees relative to the floor.
Step-by-step explanation:
When an object is parallel to the floor, it means that it is aligned with the floor at the same angle and does not slope up or down.
In other words, the angle between the shelf and the floor is 0 degrees.
So, to attach the shelf so that it is parallel to the floor, Dana should ensure that the angle between the shelf and the floor is 0 degrees.

Three large cones hang from the ceiling in an office building in front of a bank of windows. The height of each cone is 12 feet and the circumference of the base of each cone is 8π feet. The base and 50% of the lateral surface of each cone is painted red, and the rest of each cone is painted black.
What is the total surface area painted black? Use π≈3.14.
Enter your answer, rounded to the nearest tenth, in the box.
The total surface area painted black is 50.2 square feet.
How did we get the value?Let's call the radius of the base of the cone r. We can find it using the formula for the circumference of a circle:
C = 2πr
8π = 2πr
r = 4
Next, let's find the slant height of the cone, which is the distance from the tip of the cone to the base along a straight line that passes through the center of the base. We can use the Pythagorean theorem:
s^2 = r^2 + h^2
s^2 = 4^2 + 12^2
s^2 = 16 + 144
s^2 = 160
s = sqrt(160) = 12.8
Next, let's find the surface area of one cone. The surface area of a cone is equal to π times the radius of the base times the slant height, plus π times the radius of the base squared:
A = πr * s + πr^2
A = π * 4 * 12.8 + π * 4^2
A = 50.24 + 16π
A = 50.24 + 50.24
A = 100.48
Since the base and 50% of the lateral surface of each cone is painted red, that means 50% of the surface area is painted black:
black_area = 0.5 * 100.48
black_area = 50.24
Rounding to the nearest tenth, the total surface area painted black is 50.2 square feet.

Its average distance (semimajor axis) from the sun is: 67.7 AUDifference between the two dwarf planets is 28.2 AUWhat is its average distance (semimajor axis) from the sun?In order to calculate the semimajor axis of Eris, we need to plug 557 years into the equation
a=P^2/3
a= 557^0.66666667
a = 67.6971 astronomical units.
a = 67.7 AU (Rounded)
Since the average distance for Pluto from the Sun is 39.3 AU
So,
Since the distance of Eris to the sun is 67.7 AU and Pluto to the sun is 39.5
Difference between the two dwarf planets = 67.7AU - 39.5 AU
Difference between the two dwarf planets = 28.2 AU
