Step-by-step explanation:
The volume (V) of a pyramid is calculated as
V = [tex]\frac{1}{3}[/tex] area of base × height, hence
V= [tex]\frac{1}{3}[/tex] × 64 × 8 ≈ 170.7 ( to 1 dec. place )
For this case we have that by definition, the volume of a pyramid is given by:
[tex]V = \frac {1} {3} * A_ {b} * h[/tex]
Where:
[tex]A_ {b}:[/tex] It is the area of the base
h: It's the height
According to the data we have:
[tex]A_ {b} = 64mm ^ 2\\h = 8mm[/tex]
Substituting:
[tex]V = \frac {1} {3} * 64 * 8\\V = \frac {512} {3}\\V = 170.666666667[/tex]
If we round up we have that the volume is[tex]170.7 \ mm ^ 3[/tex]

Tell whether the two figures are similar. Explain your reasoning
Answer:
See below.
Step-by-step explanation:
If they were similar corresponding sides would be in the same ratio.
Testing: 5/4 = 1.25
8/6 = 4/3 = 1.333...
They are not in the same ratio so they are not similar.
Two figures are similar if their corresponding angles are congruent and their corresponding side lengths are proportional. We can determine if two figures are similar by comparing the ratios of their corresponding side lengths.
Determining whether two figures are similar involves a thorough examination of their corresponding angles and side lengths. Two figures are considered similar if their corresponding angles are congruent (equal) and their corresponding sides are in proportion, meaning that the ratios of the lengths of corresponding sides are the same throughout the figures.
First, we examine the angles. If all corresponding angles in the two figures are equal, then it's a strong indication of similarity. Similar figures have the same shape, and equal angles ensure that the shapes are the same when scaled up or down.
Next, we analyze the side lengths. For figures to be similar, the ratios of corresponding side lengths must be constant. This means that if you were to take any two sides from the first figure and divide their lengths, and then do the same for the corresponding sides in the second figure, the ratios should be equal.
In summary, similarity between two figures is established by the equality of corresponding angles and the constancy of ratios between corresponding side lengths. If both conditions are met, the figures are indeed similar, which means they have the same shape, and one can be obtained from the other through uniform scaling (enlarging or shrinking).

A golf course in Phoenix, Arizona, uses an average of 80 million gallons of water daily for irrigation. An average family of four (also living in Phoenix, AZ) uses 325,851 gallons of water per year. Rounded to the nearest ten, how many families of four can one golf course provide water for? 89,610 families 250 families 896,120 families 245 families
The golf course can provide water for approximately 89,610 families of four.
Explanation:To find out how many families of four the golf course can provide water for, we need to compare the average water usage of the golf course with the average water usage of a family of four.
The golf course uses an average of 80 million gallons of water daily for irrigation.
To convert this to gallons per year, we multiply by 365:
80 million gallons/day * 365 days/year = 29.2 billion gallons/year.
Now, we divide the total water usage of the golf course by the water usage of one family of four:
29.2 billion gallons/year / 325,851 gallons/year = approximately 89,610 families of four.
The golf course can therefore provide water for approximately 89,610 families of four.

It's not clear if this is a problem to solve or a problem to prove. Let's see where it goes.
We note the cotangent half angle formula is
[tex]\cot x = \dfrac{ 1 + \cos 2x}{\sin 2x}[/tex]
The tangent and cotangent half angle is expressible in terms of the full angle without any ambiguity, so let's set b=a/4 so a=4b.
It turns out to be true for all a (at least all a that don't make the any of the functions undefined). So it's a problem to prove.
Here's the proof. I actually did it from the bottom up, but it's better to present it this way as a proof.
We start with the cosine double angle formula:
[tex]\cos 2b = 2\cos^2 b- 1[/tex]
Multipy both sides by sin b:
[tex]\sin b \cos 2b = 2 \sin b \cos^2 b - \sin b[/tex]
Sine double angle formula:
[tex]\sin b \cos 2b = \sin 2b \cos b- \sin b[/tex]
Add sin 2b to both sides:
[tex] \sin 2b+ \sin b\cos 2b = \sin 2b + \sin 2b \cos b - \sin b[/tex]
Divide by sin b sin 2b
[tex] \dfrac{1}{\sin b} + \dfrac{\cos 2b}{\sin 2b} = \dfrac{1 + \cos b}{\sin b} - \dfrac{1}{\sin 2b}[/tex]
Turn to cosecants and cotangents. We use the cotangent half angle formula above.
[tex] \csc b + \cot 2b = \cot \frac b 2 - \csc 2b[/tex]
Substituting b=a/4:
[tex] \csc \frac a 4 + \cot \frac a 2 = \cot \frac a 8 - \csc \frac a 2 \quad\checkmark[/tex]

3x = 111
x = 37
Therefore, Value of x is 37.
Two parallel lines are crossed by a transversal then the value of x is 37.
Given that line y and line z are parallel and line x is a traversal line.
To find that value of x.
We have ∠( 3x + 4 )° and ∠ 115° are alternate interior angles in the given figure.
We know that Alternate interior angles of parallel lines are equal So,
3x + 4 = 115
3x = 115 - 4
3x = 111
x = 37

Answer:
=241 ft
Step-by-step explanation:
The building is opposite the angle of elevation. Thus using trigonometric ratios it is easier to use Tangent of the elevation angle to find the distance to the foot of the building (adjacent).
Tan ∅ = opposite/ adjacent
Tan ∅= height of the building/ distance between the engineer and the building
distance= height/tan ∅
=250/tan 46°
=241 ft

Answer: 241 feet.
Step-by-step explanation:
Observe the figure attached, where "x" is the distance from the engineer to the base of the building to the nearest whole foot.
We need to remember this identity:
[tex]tan\alpha=\frac{opposite}{adjacent}[/tex]
In this case we know that:

Therefore, the next step is to substitute these values into [tex]tan\alpha=\frac{opposite}{adjacent}[/tex]:
[tex]tan(46\°)=\frac{250}{x}[/tex]
And the final step is to solve for "x":

-4v + 2w = 7 is not a linear equation since it has v and w instead of y and x.
A linear equation is any equation in the form Ax + By = C, with the degree of each variable being 1 and the exponents strictly positive. Hence x^4 = y is not a linear equation because the exponent of x is 4.
Explanation:In mathematics, a linear equation is any equation that can be written in the form Ax + By = C, where A, B, and C are constants, and x and y are variables.

Given 2 secants intersect a circle from a point outside the circle, then
The product of the external part and the entire part of one secant is equal to the product of the external part and the entire part of the other secant, that is
x(x + 10 + x) = 6(6 + 10 + x)
x(2x + 10) = 6(16 + x) ← distribute parenthesis on both sides
2x² + 10x = 96 + 6x ← subtract 96 + 6x from both sides
2x² + 4x - 96 = 0 ← in standard form
Divide through by 2
x² + 2x - 48 = 0 ← factor the left side
(x + 8)(x - 6) = 0
Equate each factor to zero and solve for x
x + 8 = 0 ⇒ x = - 8
x - 6 = 0 ⇒ x = 6

Which values for A and B will create infinitely many solutions for this system of equations? ax-y=8 2x+y=b
Answer:
a = -2 , b = -8
Step-by-step explanation:
* Lets talk about the solution of the linear equations
- There are three types of the solutions of the system of linear equations
# If the two lines intersect each other, then there is one solution
- The equations are ax+ by = c , dx + ey = f
# If the two lines parallel to each other, then there is no solution
- The equations are ax+ by = c , ax + by = d in its simplest form ,
where a is the coefficient of x , b is the coefficient of y and
c , d are the numerical terms
# If the two lines coincide (over each other), then there are infinite
solutions
- The equations are ax+ by = c , ax + by = c in its simplest form, where
a is the coefficient of x , b is the coefficient of y and c is the
numerical term
* Lets solve the problem
∵ The system of equation is:
ax - y = 8 ⇒ (1)
2x + y = b ⇒ (2)
∵ The system create infinitely many solutions
∴ The lines are coincide
- The equations must be equal, then multiply equation(1) or (2) by -1 to
make the coefficient of y in the two equations equal
∴ -ax + y = -8
∴ 2x + y = b
∵ Their coefficients of x are equal
∵ Their coefficients of y are equal
∵ Their numerical terms are equal
∵ The coefficient of x in equation (1) is -a and in equation (2) is 2
∴ -a = 2 ⇒ multiply both sides by -1
∴ a = 2
∵ The numerical term in equation (1) is -8 and in equation (2) is b
∴ b = -8
* The values for a and b will create infinitely many solutions are -2 , -8
