The volume of the rectangular prism below is 192 cubic centimeters.
Which equation can be used to find the height of the prism?
A.h=6⋅4
B.h=192÷
(6⋅4
)
C.h=192⋅6⋅4
D.h=192−
(6⋅4
)
Answer: B. h=192÷ (6⋅4)
Step-by-step explanation:
B. h=192÷ (6⋅4)
This equation can be used to find the height of the prism because the volume of a rectangular prism can be represented by the equation V = l*w*h, where l and w are the length and width, respectively, and h is the height. In this case, given that V=192, the equation h=192÷ (l*w) can be used to find the height, where l=6 and w=4.
Math part 3 question 3
The given statement in the problem (f/g)(-2) = -6/5 is true.
What is a linear equation?A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.
We are given that;
f(x) = 3x²
g(x) x - 8 ; (f/g)(-2) = -6/5
Now,
To evaluate (f/g)(-2), we need to divide f(-2) by g(-2).
We have f(x) = 3x², so f(-2) = 3(-2)² = 12.
We also have g(x) = x - 8, so g(-2) = (-2) - 8 = -10.
(f/g)(-2) = f(-2) / g(-2) = 12 / (-10) = -6/5.
So the statement (f/g)(-2) = -6/5
Therefore, the answer according to the given equation will be true.

The solution to the system of equations is (5.56, -4.73).
To solve the system of equations by the addition method, we need to follow these steps:
Step 1: Multiply one or both of the equations by a constant to make the coefficients of one of the variables the same in both equations.
Step 2: Add the two equations together to eliminate one of the variables.
Step 3: Solve for the remaining variable.
Step 4: Substitute the value of the variable back into one of the original equations to find the value of the other variable.
Let's apply these steps to the given system:
-2x - 7y = 22
7x - 4y = -20
Step 1: Multiply the first equation by 7 and the second equation by -2 to make the coefficients of x the same:
-14x - 49y = 154
-14x + 8y = 40
Step 2: Add the two equations together to eliminate x:

The population of a town grows proportion to it's current population. The initial population is 10,000 and grows 5 % per year. Determine the population after 4 years. Also determine how long it will take the population to triple.
The population after 4 years will be 12,155.06. It will take approximately 22.52 years for the population to triple.
The population of a town grows proportionally to its current population. This means that the larger the population, the more it will grow. To determine the population after 4 years, we can use the formula:
P = P0 * (1 + r)^t
Where P is the final population, P0 is the initial population, r is the growth rate, and t is the time in years. Plugging in the values given in the question, we get:
P = 10,000 * (1 + 0.05)^4
P = 10,000 * 1.21550625
P = 12,155.06
Therefore, the population after 4 years will be 12,155.06.
To determine how long it will take the population to triple, we can use the same formula, but set P to 3 * P0 and solve for t:
3 * 10,000 = 10,000 * (1 + 0.05)^t
3 = (1 + 0.05)^t
ln(3) = t * ln(1.05)
t = ln(3) / ln(1.05)
t = 22.52
Therefore, it will take approximately 22.52 years for the population to triple.

Work out the value of x?
Using angle theorems the value of x = 67.5°
What are angle theorems?Angle theorems are rules that govern the properties of angles.
Given that we have the figure and we desire to find angle x, we proceed as folllows.
Now, we notice that one angle is a right angle and it is equal to 90°.
Also, we notice that all the angles meet at the same point.
So, we have that
x + 3x + 90° = 360° (sum of angles at a point)
Solving for x, we have that
x + 3x + 90° = 360°
4x + 90° = 360°
4x = 360° - 90°
4x = 270°
x = 270°/4
x = 67.5°

Circle’s CircumferenceThe circle's boundary is the length of the circle's circumference, sometimes referred to as its perimeter. whereas the size of a circle determines the space it occupies.
The formula for calculating a circle's circumference is written as
Circumference = πD
where D stands for the circle's diameter.
The inner circle is 44 feet in diameter. It means that
22/7 × D = 44
22D = 7 × 44 = 308
D = 308/22
D = 14 ft
The inner circle and the outer circle are separated by 2 feet. This implies that the outer circle's diameter would be
14 + 2 + 2 = 18 ft
Circumference of the outer circle is

Therefore , the solution of the given problem of probability comes out to be roughly 0.2667, or 26.67%.
What is probability exactly?The primary goal of the schemes within a technique known as criteria is the evaluation of the likelihood that a claim is accurate or that a specific event will occur. Any figure between 0 and 1, with 0 typically signifying probability and 1 typically signifying a degree of certainty, can represent chance. A probability diagram shows the chance that a specific event will occur.
Here,
We can use combinations and probability to fix this issue.
First, we can determine how many different methods there are to choose 2 individuals from a group of 15:
=> C(15,2) = 105 is the total number of options.
Next, we can determine how many options there are to choose two women from a group of eight women:

The likelihood that the two selected to respond to queries will both be women is as follows:
P(both women) equals the variety of methods to choose two women (total number of ways)
=> P(all females) = 28/105
=> P(all females) = 0.2667

Communicate and Justify. Is it possible to use only translations and dilations to map one circle to another? Explain.
Answer: It is not possible to use only translations and dilations to map one circle to another unless the two circles are identical in size and shape.
A translation is a transformation that moves an object without changing its size, shape, or orientation. It involves moving every point on the object the same distance in the same direction. Since a circle is defined by all the points that are equidistant from its center, a translation will simply move the entire circle in the same direction, but will not change its size or shape.
A dilation is a transformation that changes the size of an object, but not its shape or orientation. It involves multiplying the distance of every point on the object from a fixed center point by a scale factor. While a dilation can change the size of a circle, it will also change the distance between points on the circle, and thus change its shape.
Therefore, if the two circles are not identical in size and shape, it would be necessary to use other transformations, such as rotations or reflections, to map one circle to the other.

Explain in detail why the area of a trapezoidal region is 1/2h(a+b), where a & b are the lengths of the two parallel sides, and he is the height.
The area of a trapezoidal region is 1/2h(a+b), where a and b are the lengths of the two parallel sides, and h is the height.
The area of a trapezoidal region is given by the formula A = 1/2h(a+b), where a and b are the lengths of the two parallel sides, and h is the height. This formula can be derived by dividing the trapezoid into two right triangles and a rectangle, and finding the area of each of these shapes.
First, let's consider the two right triangles. The height of each of these triangles is h, and the lengths of their bases are (a-b)/2 and (b-a)/2, respectively. The area of each of these triangles is therefore 1/2h(a-b)/2 = 1/4h(a-b).
Next, let's consider the rectangle. The length of this rectangle is b, and the height is h. The area of this rectangle is therefore bh.
The area of the trapezoidal region is the sum of the areas of the two right triangles and the rectangle. This gives us:
A = 1/4h(a-b) + 1/4h(b-a) + bh
Simplifying this equation gives us:
A = 1/2h(a+b)
Therefore, the area of a trapezoidal region is 1/2h(a+b), where a and b are the lengths of the two parallel sides, and h is the height.

Step-by-step explanation:
a=55 because
75+50+a=180 (Sum of angle in a stratight line)
or, 125+a=180
or, a=180-125
a=55
b=75 because they are alternate angles
c=50 because they are alternate angles
d=50 Because d=c(vertically opposite angle) and c=50
