Both pyramids in the figure have the same base area as the prisme
The ratio of the combined volume of the pyramids to the volume of the prism,expressed as a fraction in simplest form,is 1/3.
How to calculate the ratio?The volume of a pyramid is (1/3) (base area) (height)
Volume of the lower pyramid = (1/3) (base area) (height) Volume of the upper pyramid = (1/3) (basearea × height)
The combined volume of both pyramids = (2/3) × (base area) (height) .
Their base area is (length x width) of the prism, and their height is (1/2 the height) of the prism.
From here, we'll work with the dimensions of the prism ... L, W, and H .
Combined volume of the pyramids = (2/3) (L x W) (1/2 H)
= (1/3) (L x W x H) .
Volume of the prism = (L x W x H)
The pyramids occupy 1/3 the volume of the prism.
The ratio is 1/3 .

At the beginning of the week, Naveen has 87 trading cards. On Monday, he gets 9 more. On Tuesday, he gives 16 away. On Wednesday, he is given 3 by a friend. On Thursday, he sells all of his cards to a collector. The collector pays him a rate of c for every card that Naveen has. If Naveen earns $124.50 from the sale, what is c, the rate that the collector pays for each card?
A) $1.08
B) $1.50
C) $41.50
D) $83.00
PLEASE ANSWER CORRECTLY!!!!!!!!
HURRY!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
B) $1..50

What is an equation in standard form of the line that has x-intercept 1 and y-intercept 4?
A. x-4y=4
B. 4x-y=4
C. 4x+y=4
D. x-4y=-4
The equation of the straight line that has x-intercept 1 and y-intercept 4 is:
4x - y = 4
What is a straight line?"A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined on both sides of a point."
Given, the line has a x-intercept of 1 and y-intercept of 4. T
Therefore, the line passes through the points (1, 0) and (0, 4).
Now, we can find the slope of the line 'm' that passes through those either points.
Therefore, (x₁ - x₂) = m(y₁ - y₂)
⇒ (1 - 0) = m(0 - 4)
⇒ m = [tex]\frac{1}{4}[/tex]
Now, the equation of the line that has x-intercept 1 and y-intercept 4 is:
(x - x₁) = m(y - y₁)
⇒ (x - 1) = [tex]\frac{1}{4}[/tex](y - 0)
⇒ 4(x - 1) = y
⇒ 4x - y = 4

Answer:
x = no solutions
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define equation
4x - 5 = x - 1 + 3x
Step 2: Solve for x
Combine like terms: 4x - 5 = 4x - 1Subtract 4x on both sides: -5 ≠ -1Here we see that -5 does not equal -1.
∴ This equation has no solutions.
Explain why f(x) = x^2-x-6/x^2-9 is continuous at x = 2.
a. f is defined at x = 3
b. f is not defined at x = 2
c. f is defined at x = -3
d. f is defined at x = 2
The correct answer is option D. ([tex]f[/tex] is defined at [tex]x = 2[/tex])
The rational Function is continuous at a given value if its Denominator is not zero. In this exercise, we proceed to Factor the expression by check the value Denominator for each value of [tex]x[/tex].
[tex]f(x) = \frac{x^{2}-x-6}{x^{2}-9}[/tex]
[tex]f(x) = \frac{(x-3)\cdot (x+2)}{(x+3)\cdot (x-3)}[/tex]
As we can see, [tex]f[/tex] is not defined for [tex]x = -3[/tex] and [tex]x = 3[/tex]. Hence, we conclude that right answer is D.

Step 2: Identify Variables
a = 3

c = -1
Step 3: Find roots
Substitute [Quad Formula]: [tex]x=\frac{7\pm\sqrt{(-7)^2-4(3)(-1)} }{2(3)}[/tex]Evaluate Exponents: [tex]x=\frac{7\pm\sqrt{49-4(3)(-1)} }{2(3)}[/tex]Multiply: [tex]x=\frac{7\pm\sqrt{49+12} }{6}[/tex]Add: [tex]x=\frac{7\pm\sqrt{61} }{6}[/tex]Answer:
x = 7 + √61 ÷ 6
Step-by-step explanation:
3p² - 7p - 1 = 0 is a given equation
3p² - 7p - 1 = 0
Here,
a = 3
b = - 7
c = - 1
Now, Discriminant
D = b² - 4ac
= (- 7)² - 4 (3)(- 1)
= 49 + 12
D = 61 > 0
So, Quadratic Equation
ax² + bx + c = 0
x = - b ± √b² - 4ac ÷ 2a
x = - (- 7) ± √(- 7)² - 4 (3)(- 1) ÷ 2(3)
x = 7 ± √61 ÷ 6
x = 7 ± √61 ÷ 6
x = 7 + √61 ÷ 6 or x = 7 - √61 ÷ 6
∴ Not real Value
Thus, The real value of x is 7 + √61 ÷ 6

The linear regression equation that represents this set of data is Y = -12.41 + 1.15x and the projected test grade for a student with a homework grade of 49 is 44 and this can be determined by using the generalized equation of regression.
Given :
A mathematics teacher wanted to see the correlation between test scores and homework. The homework grade (x) and test grade (y) are given in the accompanying table.The generalized regression equation is given below:
Y = a + bX --- (1)
where b is given by the formula:
[tex]\rm b = \dfrac{N\sum XY-\sum X \sum Y}{N\sum X^2-(\sum X)^2}[/tex]
Now, substitute the values of the known terms in the above formula in order to determine the value of 'b'.
b = 1.15
and the formula of a is given below:
[tex]\rm a = \dfrac{\sum Y - b \sum X}{N}[/tex]

A 100 g ball and a 50 g ball are dropped from a tower. both balls are the same size and there is no air resistance. which answer best describes how they fall? responses both balls hit the ground at the same time. both balls hit the ground at the same time. the 100 g ball hits the ground first. the 100 g ball hits the ground first. the 50 g ball hits the ground first.
When the 100 g ball and a 50 g ball are dropped from a tower. both balls are the same size and there is no air resistance, B. both balls hit the ground at the same time.
How to illustrate the information?When an object moves through the air, air resistance acts as a force. When a body is moving through the air, this force works in the opposite direction. A frictional force is applied to the moving body by air resistance. Air resistance causes a body's speed to slow down as it moves.
Because air resistance slows down the motion of the falling object, it impacts acceleration during a fall to a lesser extent than gravity (g). The object's surface area and speed both influence how much it slows down.
Therefore, when the 100 g ball and a 50 g ball are dropped from a tower. both balls are the same size and there is no air resistance, both balls hit the ground at the same time.
