Answer:
30/100
Step-by-step explanation:
25%= 25/100
50%= 50/100
3/100 is in the middle of the two fractions. So one of the possible answer can be 30/100 or 30%
Answer:
[tex]\sf \dfrac{2}{5}[/tex]
Step-by-step explanation:
"per cent" means "per hundred". Therefore, to change a percent to a fraction, remove the % sign and place the number as the numerator of a fraction with 100 as the denominator.
[tex]\sf 25\%=\dfrac{25}{100}[/tex]
[tex]\sf 50\%=\dfrac{50}{100}[/tex]
Any percent between 25% and 50% can be written as a fraction in the same way.
Choose a number between 25 and 50, place it as the numerator of a fraction with 100 as the denominator:
[tex]\sf \dfrac{40}{100}[/tex]
Now reduce the fraction to its simplest term by dividing the numerator and denominator by the greatest common factor (GCF):
[tex]\sf \dfrac{40 \div 20}{100\div 20}=\dfrac{2}{5}[/tex]
Therefore, the fraction ²/₅ is between 25% and 50% as it is equivalent to 40%.

a triangle with an area of 15 units2
A polygon with the given area is given below.
What is Polygons?Polygons are closed figures which has at least three set of line segments joined together.
The polygon with least number of sides is triangle.
We have to draw a triangle of area 15 unit².
Area of the triangle = [tex]\frac{1}{2}[/tex] × Base × Height
[tex]\frac{1}{2}[/tex] × Base × Height = 15
Base × Height = 30
Let base = 6 units, height = 5 units
We can draw a right triangle this way as shown below.
If we are starting from the point A(0, 0), a length of base of 6 units will be a line segment from A(0, 0) to B(6, 0).
If the height is 5 units, draw a line segment from B(6, 0) to C(6, 5).

A company plant to market a model of a plant that is 96 feet and 8 inches long with a wing Spand of 56 feet choose a reasonable scale for this model and find the length and wingspan of the model explain why you chose the scale and why did it
The length of the model is 3.33 feet and the wingspan is 1.87 feet, which are reasonable and manageable sizes for a model of this type.
What is scale conversion?
Scale conversion is the process of determining the size of a model based on the size of the original object being modeled.
One way to determine a reasonable scale for the model is to consider the desired size of the model relative to the actual size of the plane. For example, if we want the model to be 1/30th the size of the actual plane, we can use the following formula to find the length and wingspan of the model:
Model length = Actual length ÷ Scale factor
Model wingspan = Actual wingspan ÷ Scale factor
Using these formulas, the length of the model would be:
Model length = 96 feet + 8 inches ÷ 30 = 3 feet 4 inches ÷ 30 = 3.33 feet
And the wingspan of the model would be:
Model wingspan = 56 feet ÷ 30 = 1.87 feet
The reason for choosing a 1/30th scale factor is that it results in a model that is relatively small but still large enough to show the details of the design. It also provides a good balance between size and detail, allowing the model to be easily handled and displayed while still showcasing the key features of the actual plane.
Using this scale, the length of the model is 3.33 feet and the wingspan is 1.87 feet, which are reasonable and manageable sizes for a model of this type.

What is the interest rate?
The amount of interest due each period expressed as a percentage of the amount lent, deposited, or borrowed is known as an interest rate. The total interest on a loaned or borrowed sum is determined by the principal amount, the interest rate, the frequency of compounding, and the period of time the loan, deposit, or borrowing took place.
Here, we have
Given: A taxpayer who pays 22% in taxes each year has these two accounts. Account 1: $10000 is placed in a tax-deferred account that pays 2.1% interest compounded annually for 25 years. Account 2: $10000 is placed in a taxable account that pays 3.1% interest compounded annually for 25 years.
b. His real annual interest rate is the interest rate decreased by the product of the interest rate and the tax rate.

What is SAS theorem?The triangles are congruent if two sides and the included angle of one triangle are equivalent to two sides and the included angle of another triangle. Congruent refers to figures that are similar in all respects, primarily in terms of size and shape. Congruence describes how two congruent figures relate to one another.
From the given picture, it is clear that WXYV is a rectangle.
∠VYX = 90°
As we know, ∠YVX + ∠VYX + ∠VXY = 180°
or, 5x - 12° + 90° + 2x - 3° = 180°
or, 7x = 180° - 90° + 15°
or, 7x = 105°
or, x = 15°
thus, ∠VXY = 2x - 3° = 27°
next comparing ΔVYX and ΔYVW we get:
VY = VY
WV = XY
So, ∠VYX = ∠XVW = 90°
From SAS theorem,
ΔVYX ≅ ΔYVW
∠VWX = ∠VXY = 27°

The minimum frequency of radiation is 0.603 × 10¹⁵ and the longest wavelength is 4.97 × 10⁻⁷.
What is Planck's Equation?Planck's equation is an equation which describes about the amount of spectral radiance radiated by a black body at a certain wavelength in thermal equilibrium.
We have the Planck's Equation,
E = hv,
where E is the energy, h is the Planck's constant = 6.63 x 10⁻³⁴ J and v is the frequency of radiation.
We have in the question E = 4.0×10⁻¹⁹ J
Substituting,
4.0×10⁻¹⁹ = (6.63 x 10⁻³⁴) v
v = (4.0×10⁻¹⁹) / (6.63 x 10⁻³⁴)
= 0.603 × 10¹⁵
Also we have the equation to find the wavelength,
v = c / λ, where c is the speed of the light = 3 × 10⁸ and λ is the wavelength.
λ = c / v = (3 × 10⁸) / (0.603 × 10¹⁵)

A certain amount of money is shared between Harvey and Mike in the ratio 4:3. If Mike gets £ 75 less than Harvey, find the total amount of money.(will mark brainliest)
Based on their sharing ratio of 4:3, when Mike gets £ 75 less than Harvey, the total amount of money shared is $525.
How is the total amount determined?The total amount being shared between Harvey and Mike is determined using the arithmetic of ratios.
Firstly, we determine the sum of ratios as 7. Since Mike's share is 3/7, which is less by £75 than Harvey's share, which is 4/7, we find the difference as 1/7 and equate it to £75.
Proportionately, if 1/7 equals £75, the total sum being shared will be equal to $525 (£75 x 7/1)
Sharing ratio between Harvey and Mike = 4:3
Sum of ratios = 7
Let the amount Harvey gets = x
x = 4/7
Let the amount Mike gets = x - 75
x - 75 = 3/7
4/7 - 3/7 = 1/7
1/7 = £75

If a stimulus plus a response results in a satisfying outcome, the probability of that response occurring again ________. Question 24 options: is not affected decreases increases depends on the CS-UCS relationship
The answer is option (C) increases. If a stimulus plus a response results in a satisfying outcome, the probability of that response occurring again increases.
This is called the law of effect, which states that behaviors with positive outcomes are more likely to be repeated in the future.
When a response is followed by a satisfactory outcome, the person is more likely to associate that response with a positive outcome and is more likely to repeat that response in future situations.
This law is based on the concept of reinforcement, ie when an environmental stimulus favors the repetition of a behavior. This law was first proposed by psychologist Edward Thorndike in the early 20th century.

Mrs. Thapa wishes to grow flowers on the hanging bowls at her home. She brings 16 hemispherical bowls from the market having internal diameter 21 cm and uniform thickness 0.5 cm each and fills the bowls with compost completely. (i) If 1 cm³ of compost weighs 2.31 gm, find the total weight of required compost (ii) If she covers outer curved surface of each bowl with polythene sheet, find the total amount of polythene.
Answer: (i) To find the total weight of compost required:
First, find the volume of one bowl: We can use the formula for the volume of a sphere to find the volume of one hemispherical bowl. The radius of the sphere is equal to half the diameter of the bowl, which is 21 cm / 2 = 10.5 cm. The volume of one hemispherical bowl is given by the formula (4/3)πr^3/2, where r is the radius. Plugging in the values, we get:
(4/3)π(10.5)^3/2 = (4/3) * (22/7) * (10.5)^3/2 = 532.8 cm³
Multiply by the number of bowls: To find the total volume of compost required, multiply the volume of one bowl by the number of bowls: 532.8 cm³ * 16 bowls = 8544.8 cm³
Multiply by the weight of compost per cm³: To find the total weight of compost, multiply the total volume by the weight of compost per cm³: 8544.8 cm³ * 2.31 gm/cm³ = 19824.9 gm = 19.82 kg
So, the total weight of compost required is 19.82 kg.
(ii) To find the amount of polythene required:
First, find the circumference of one bowl: The circumference of the circle is equal to 2π times the radius. So, the circumference of one bowl is 2π * 10.5 cm = 21π cm.
Find the length of the polythene: To find the length of the polythene, we need to find the length of the curved surface of the bowl. We can use the formula for the circumference of a circle, which is 2πr, where r is the radius. The curved surface of the bowl is half the circumference of the circle, so the length of the polythene is 21π cm / 2 = 10.5π cm.
Multiply by the number of bowls: To find the total length of the polythene, multiply the length of one bowl by the number of bowls: 10.5π cm * 16 bowls = 168π cm = 528 cm (rounded to the nearest cm)
So, the total amount of polythene required is 528 cm.

45 kg of one nut and 45 kg of another nut should be mixed in order to get 60 kg of a mixture worth $4.80kg.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 7 is an equation.
We have,
One nut = x kg
Cost = $5
Other nuts = y kg
Cost = $4.20
Now,
From the given statement we can make two equations.
x + y = 60
x = 60 - y
Substituting here,
5x + 4.20y = 4.80
5 (60 - y) + 4.20y = 4.80 x 60
300 - 5y + 4.20y = 288
300 - 288 = 5y - 4.20y
12 = 0.8y
y = 12/0.8
y = 15
Now,
x = 60 - 15
x = 45
Thus,
45 kg of one nut and 45 kg of another nut.

What is the slope-intercept form?In Mathematics, the slope-intercept form of a line can be calculated by using this linear equation:
y = mx + c
Where:
x and y represents the data points.m represents the slope of a line.c represents the y-intercept of a line.What is y-intercept?In Mathematics, the y-intercept is also referred to as an initial value and the y-intercept of any graph such as a linear function, generally occur at the point where the value of "x" is equal to zero (x = 0).
In this scenario, the y-intercept of this equation can be calculated as follows;
y = 30 + 10x
