Part (a)
The smaller pyramid up top is the result of slicing at the halfway point.
This leads to the ratio 1:2 when comparing small side to larger side.
Cube both parts of that ratio to end up with 1:8 as the volume ratio.
This means if the smaller pyramid was say 1 cubic foot in volume, then the larger pyramid has a volume of 8 cubic feet.
-------------------------
Part (b)
Consider the case that,
volume of smaller pyramid = 1 cubic feetvolume of larger pyramid = 8 cubic feetThe volume of the truncated base is 8-1 = 7 cubic feet.
The ratio of the smaller pyramid to the truncated base is 1:7

what is the answer to this question: Tadeo volunteered at the library 6 times as many hours over the weekend as Dylan. Together, they volunteered a total of 14 hours. How many hours did each person volunteer over the weekend?
Answers
Answer:
Tadeo: 12 hoursDylan: 2 hoursStep-by-step explanation:
We can let d represent the number of hours that Dylan volunteered. Then Tadeo volunteered for 6d hours, and their total hours were ...
d +6d = 14
7d = 14 . . . . . . collect terms
d = 2 . . . . . . . divide by the coefficient of d
6d = 6(2) = 12
Tadeo volunteered 12 hours; Dylan volunteered 2 hours.

Answers
Answer:
Equation: y = 2x + 25
Step-by-step explanation:
Here x determines the number of year. For the first year,we will see ( 2 * 1 ) = $2 increase. In the second year, ( 2 * 2 ) =$4 increase and like this goes on, whereas the $25 being constant. "y" determines the total cost for each year.

Which is a factor of x2 – 9x 14? x – 9 x – 2 x 5 x 7.
Answers
Answer:
Step-by-step explanation:
The 2 factors of x^2 - 9x + 14 are (x - 7) and (x - 2) because -7 + -2 = -9 and -7 x -2 = 14.
The factors of the quadratic expression x² – 9x + 14 is (x - 7)(x - 2) option (B) (x - 2) is correct.
What is a quadratic function?Any function of the form [tex]\rm f(x) =ax^2+bx+c[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic function.
It is given that:
The quadratic expression is:
= x² – 9x + 14
Using factor method:
= x² – 7x - 2x + 14
= x(x - 7) - 2(x - 7)
= (x - 7)(x - 2)
The factors of the quadratic expression x² – 9x + 14 is (x - 7)(x - 2)
Thus, the factors of the quadratic expression x² – 9x + 14 is (x - 7)(x - 2) option (B) (x - 2) is correct.

Find the coordinates of B, C, and D given that AB=5 and BC = 10
Answers
Answer:
B = (3, -5)
D = (0, -1)
C = (3, 5)
Step-by-step explanation:
We want to find the coordinates of B, C, and D given that AB = 5 and BC = 10.
Because AB = 5 and BC = 10, we can find the slope of the line using the slope formula:
[tex]\displaystyle \begin{aligned} m & = \frac{\Delta y}{\Delta x} \\ \\ & = \frac{(10)}{(5)} \\ \\ & = 2 \end{aligned}[/tex]
Point A(-2,-5) is on the line. Hence, the equation of the line is:
[tex]\displaystyle \begin{aligned} y-y_1 &= m(x-x_1) \\ \\& = y-(-5) = 2(x-(-2)) \\ \\ y + 5 & = 2x+4 \\ \\ y & = 2x-1 \end{aligned}[/tex]
Because AB is 5, B is simply A shifted rightwards five units. Hence:
[tex]\displaystyle B = (-2+5, -5) = (3, -5)[/tex]
At Point D, x = 0. Hence:
[tex]\displaystyle y = 2(0) -1 = -1[/tex]
Thus, D is at (0, -1).
B and C are collinear. Hence, the x value of C is 3:
[tex]\displaystyle y = 3(2) - 1 = 5[/tex]
Therefore, C is at (3, 5).

The sum of three times a number (x) and -23−23 is 2828.
Answers
Answer:
3x - 23 = 2828
Step-by-step explanation:
I'll assume the question is supposed to read "The sum of three times a number (x) and −23 is 2828."
"three times a number (x)" can be written as 3x
"sum of three times a number (x) and −23" means 3x - 23
"is 2828" = 2828
Put them together:
3x - 23 = 2828

You have learned what tangent lines are. You have learned that they are perpendicular to the radius at a point on the circle. What is unique about a tangent line is that it touches the circle at exactly one point, but never goes inside the circle. But points are infinitely small … how can a line touch a circle without ever going into it?
Answers
Answer:
In Euclidean plane geometry, a tangent line to a circle is a line that touches the circle at exactly one point, never entering the circle's interior. Tangent lines to circles form the subject of several theorems, and play an important role in many geometrical constructions and proofs.
