The smaller angle made by the two hands of the clock at 3 o'clock is 90 degrees.
What is an angle?A figure known as an angle is created by two rays or line segments that meet at a place known as the vertex of the angle. The sides or legs of the angle are other names for the rays or line segments.
According to question:To determine the smaller angle made by the two hands of a clock when it is 3 o'clock, we can use the following formula:
angle = |(11/2) * m - 30h|
where:
m is the number of minutes past the hour (in this case, since it is 3 o'clock, m = 0)
h is the hour (in this case, h = 3)
By using this formula, we get:
angle = |(11/2) * 0 - 30(3)| = |0 - 90| = 90
Therefore, the smaller angle made by the two hands of the clock at 3 o'clock is 90 degrees.

A company knows that 32% of their customers order their product in Black and 26% in White and 22% in Grey.
2 orders are made, Find the probability that both are the same color.
(both black, white or grey)
round to 4 d.p.
After considering all the given data and running a series of calculation we reach the conclusion that the probability of receiving both orders as the same colors is 0.2184, under the condition that a company has the information that 32% of their customers order their product in Black and 26% in White and 22% in Grey.
Then the evaluated probability of both orders being the same color can be found by applying summation of the probability of both orders being black, both orders being white, and both orders being grey.
Now, the probability of both orders being black is 0.32 × 0.32
= 0.1024.
Similarly the probability of both orders being white is 0.26 × 0.26
= 0.0676.
Lastly, the probability of both orders being grey is 0.22 × 0.22
= 0.0484.
Hence, the evaluated probability of both orders being the same color is 0.1024 + 0.0676 + 0.0484 = 0.2184 (rounded to four decimal places).

what is integers ?All entire numbers (optimistic, negative, and zero) as well as their opposites are included in the category of integers. These can be visualised as evenly spaced-apart points with zero in the middle on a number line. The following numbers are part of the set of integers, which is represented by the symbol Z . The numbers of pupils in an educational setting, the weather in degrees Celsius, or the location of an object in relation to a reference point are all examples of quantities that can be represented by integers and are counted or measured in whole units. They adhere to specific arithmetic laws and can be added, deducted, multiplied, and divided.
given
Assume that x and y are the two positive integers, with x being the greater of the two. Finally, we may convert the provided data into equations:
In order to remove x, we can replace the first equation with the second equation as follows:
[tex](2y-2)^2 + y^2 = 260[/tex]
Adding and subtracting:
[tex]4y^2 - 8y + 4 + y^2 = 260[/tex]
combining comparable phrases
[tex]5y^2 - 8y - 256 = 0[/tex]
Using the quadratic formula, we can solve this quadratic equation:
y = [8 ± sqrt(8^2 - 45(-256))] / (2*5)
y = [8 ± sqrt(3368)] / 10
y ≈ 8.6 or y ≈ -9.4
Y must be 8 because we are seeking for positive integers. The first equation can then be used to determine x:
x = 2y - 2 = 2(8) - 2 = 14
Hence, 8 and 14 are the two positive integers as Y must be 8 because we are seeking for positive integers.

The solution to the equation 2,401 = 7⁶⁻²ˣ is x ≈ 1.4076.
Define logarithmIn mathematics, a logarithm is the inverse operation to exponentiation. Given a base b and a positive number y, the logarithm of y with respect to the base b is the exponent to which b must be raised to yield y. In other words, if x is the logarithm of y with respect to base b, then bˣ = y.
We can begin solving this equation by isolating the exponential term on one side of the equation and taking the logarithm of both sides.
2,401 = 7⁶⁻²ˣ
Taking the logarithm base 7 of both sides:
log₇(2,401) = log₇(7⁶⁻²ˣ )
Using the property of logarithms that states that log base a (aᵇ) = b, we can simplify the right-hand side of the equation:
log₇(2,401) = (6-2x)log₇(7)
Since log₇(7) = 1, we can further simplify:
log₇(2,401) = 6-2x
-2x = log₇(2,401) - 6
x = (6 - log₇(2,401))/2
Using a calculator, we find:
x ≈ 1.4076
Therefore, the solution to the equation 2,401 = 7⁶⁻²ˣ is x ≈ 1.4076.

Suppose that you were 24 inches long at birth and 4 feet tall on your tenth birthday. Based on these two data points, create a linear equation for the function that describes how height varies with age. Use the equation to predict the height at age 9 and 31
An equation for this linear function that describes how height varies with age is y = 1/5(x) + 2.
The predicted height at 9 is 3.8 feet.
The predicted height at 31 is 8.2 feet.
How to determine an equation of this line?In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical expression:
y - y₁ = m(x - x₁)
Where:
x and y represent the data points.m represent the slope.Conversion:
1 feet = 12 inches
24 inches = 24/12 = 2 feet.
Next, we would determine the slope of this line;
Slope (m) = (y₂ - y₁)/(x₂ - x₁)
Slope (m) = (4 - 2)/(10 - 0)
Slope (m) = 2/10
Slope (m) = 1/5
At data point (0, 2) and a slope of 1/5, a linear equation for this line can be calculated by using the point-slope form as follows:
y - y₁ = m(x - x₁)
y - 2 = 1/5(x - 0)
y = 1/5(x) + 2
When x = 9, the predicted height is given by;
y = 1/5(9) + 2
y = 3.8 feet.
When x = 31, the predicted height is given by;
y = 1/5(31) + 2
y = 8.2 feet.

Let
u = 4i - j v = 3i + j w = i + 3j
Find the specified scalar.
u(v + w)
The specified scalar is 12 as the result of u(v + w) is 12i + 12j.
The provided vectors are given to be u = 4i - j v = 3i + j w = i + 3j. First, we need to find the vector v + w,
v + w = (3i + j) + (i + 3j)
v + w = 4i + 4j
Now, we can find dot product, u(v + w),
u(v + w) = u(4i + 4j)
u(v + w) = 4ui + 4uj
Substituting the given values of u, we get,
u(v + w) = 4(4i - j)i + 4(4i - j)j
u(v + w) = 16i - 4j + 16j - 4i
Simplifying, we get,
u(v + w) = 12i + 12j
Therefore, the specified scalar is 12.

If the prism on top of the figure was 4 inches tall instead of 3 inches tall, what would be
the difference between the volume of the original prism on top and the new prism on
top?
Answer:
L * W
Step-by-step explanation:
To find the difference in volume between the original prism and the new prism, we need to calculate the volume of each prism and then subtract the volumes.
Let's assume the base of the prism is a rectangle with length L, width W, and height H.
The volume of a prism is given by V = L * W * H.
Original Prism:
Height = 3 inches
Volume = L * W * 3
New Prism:
Height = 4 inches
Volume = L * W * 4
The difference in volume between the original prism and the new prism is:
New Prism Volume - Original Prism Volume = (L * W * 4) - (L * W * 3)
= L * W * (4 - 3)
= L * W
Therefore, the difference in volume is L * W.
Since we do not have specific dimensions or values for L and W, we cannot calculate the exact difference in volume. We would need additional information to determine the values of L and W or their relationship to find the difference in volume.

The volume of a suitcase is 8,556 Cubic
inches. It is 32 inches long and 15.5
inches high. Write an equation to
represent the width. Then find the width
of the suitcase.
To find the width of the suitcase, we need to use the formula for the volume of a rectangular prism:
Volume = Length × Width × Height
Given the volume of the suitcase as 8,556 cubic inches, the length as 32 inches, and the height as 15.5 inches, we can write the equation:
8556 = 32 × w × 15.5
Simplifying this equation, we can divide both sides by the product of 32 and 15.5:
8556 ÷ (32 × 15.5) = w
Solving for w, we get:
w ≈ 16.50 inches
Therefore, the width of the suitcase is approximately 16.50 inches.

Answer:
The surface area of the square pyramid is 18 km².
Step-by-step Explanation:
What is the surface area of a square pyramid with a slant height?
The surface area of a square pyramid with a slant height can be determined by the product of the base perimeter with the slant height divided by two.
Mathematically, it can be expressed as:
Surface Area S.A = P × l/2
where;
Side length (a) = 3
Base perimeter (P) = 4a = 4(3) = 12km
Slant length (l) = 3 km
Surface Area (S.A) = 12 × (3/2)
Surface Area (S.A) = 12 x 1.5 = 18 km²
Therefore, the surface area of the same pyramid is 18 square km.
[tex]\sf SA_{Pyramid} =\boxed{\sf 27km^{2}}.[/tex]
Step-by-step explanation:We're asked to calculate the surface area (SA) of a pyramid. Surface area of a tridimensional shape isn't more than calculating the area of all of its "faces" and then adding them all together. Some of these tridimensional shapes already have equations that provide a direct calculation of this parameters, without the need to add together the area of the different parts of the shape.
There's a developed formula for directly calculating the surface area of square pyramids, but in this case it is easier to just calculate the individual areas of each face and add them all together.
1. Calculate the area of the base.This is pretty easy to calculate, as the base forms the shape of a square. Therefore, multiplying the length and width of this square will give us that area:
[tex]\sf A_{Base} =lw=3km*3km=\boxed{\sf 9km^{2}} .[/tex]
Check attached image 1 to see where we got these values from.
2. Calculate the area of one triangular face.So these faces form the sape of a triangle. Therefore, mul;tiplying their lengh by width and then dividing by 2 should give us the area.
[tex]\sf A=\dfrac{lw}{2} =\dfrac{(3km)(3km)}{2}=4.5km^{2}.[/tex]
Check attached image 2 to see where we got these values from.
This is the area of an individual triangular face of the pyramid, but we have a total of 4 faces. Hence, let's multiply this area by 4 to find the total area of all triangular faces:
[tex]4.5km^{2} *4=\boxed{\sf 18km^{2}}.[/tex]
3. Calculate the total surface area.So the total surface area, as stated at the beginning of this answer, is given by the addition of all individual areas from all the faces of the shape, so let's do just that:
[tex]\sf SA_{Pyramid} =9km^{2} +18km^{2}=\boxed{\sf 27km^{2}}.[/tex]
