Volume of a pyramid = [tex]\frac{1}{3}(\text{Area of the rectangular base})(\text{Height})[/tex]
Area of the rectangular base = Length × Width
= 8 × 6
= 48 mm²
Volume of the pyramid = 192 mm³
192 = [tex]\frac{1}{3}(48)h[/tex]
h = [tex]\frac{192}{16}[/tex]
h = 12 mm
Therefore, all the pyramids having height less than 12 mm will be fitted inside the given pyramid.

You roll a standard number cube 36 times, how many times can you expect to roll an odd number?
Answers
Answer:
18 times
Step-by-step explanation:
Half of the possibilities you can roll are correct. so 18 out of 36 times you roll an odd number.
You could also look at it another way. You can expect to roll each number 6 times, so the 3 odd numbers added together is 18 times.
Marcos purchased a sail boat for $56,900. He anticipates each year the boat will decrease in value by 8.1% from the previous year. Write an exponential function that models the value in dollars of the boat x years after Marcus's purchase.
Answers
Answer: [tex]56,900\left( 0.919\right)^x[/tex]
Step-by-step explanation:
Given
Marcos purchased a sailboat for [tex]\$56,900[/tex]
Each year the boat will decrease in value by [tex]8.1\%[/tex]
After 1 year it is
[tex]\Rightarrow 56,900-56,900\times 0.081\\\Rightarrow 56,900\left( 1-0.081\right)\\[/tex]
after another year it becomes
[tex]\Rightarrow 56,900\left( 1-0.081\right)-56,900\left( 1-0.081\right)\times 0.081\\\Rightarrow 56,900\left( 1-0.081\right)\cdot \left( 1-0.081\right)\\\Rightarrow 56,900\left( 1-0.081\right)^2[/tex]
After [tex]x[/tex] years it is
[tex]\Rightarrow 56,900\left( 1-0.081\right)^x[/tex]
[tex]\Rightarrow 56,900\left( 0.919\right)^x[/tex]
why is this true 9a=11a-2a
Answers
Answer:
9a = 11a - 2a
9a = 9a
Step-by-step explanation:
9a = 11a - 2a
11 - 2 = 9
Similarly, 11a - 2a = 9a
Eleven minus two equals nine. Similarly, 11a minus 2a equals 9a. You can subtract them because they both have the same variable a.

Which statements about this system of equations are true? Check all that apply. Negative x + 6 y = 16. 8 x minus 6 y = negative 2. The x-variable will be eliminated when adding the system of equations. The y-variable will be eliminated when adding the system of equations. The sum of the system of equations is Negative 8 x = 14. X = 2 y = 3 There is only one solution to the system of equations.
Answers
Answer:
The y-variable will be eliminated when adding the system of equations.
There is only one solution to the system of equations.
Step-by-step explanation:
-x + 6y = 16 (1)
8x - 6y = -2 (2)
Add the equations to eliminate y
-x + 8x = 16 +(-2)
7x = 16 -2
7x = 14
x = 14/7
x = 2
Substitute x = 2 into (1)
-x + 6y = 16 (1)
-2 + 6y = 16
6y = 16 + 2
6y = 18
y = 18/6
y = 3
(x, y) = (2, 3)

Declan says that any number n, the product 4 times n is greater than 4. Which value of n shows why declan is incorrect
Answers

Step-by-step explanation:
Given
The product of 4 times n is greater than 4 i.e.
[tex]\Rightarrow 4\times n>4\\\text{Dividing both side of inequality by 4}\\\\\Rightarrow \dfrac{4n}{4}>\dfrac{4}{4}\\\\\Rightarrow n>1[/tex]
It can be said that the value of n must be greater than 1.
The area of a rectangle is 24x5y7 square yards. If the length of the rectangle is 3x2y6, which expression represents the width of the rectangle in yards?
Answers
Answer: [tex]8x^3y[/tex]
Step-by-step explanation:
Given
The area of a rectangle is [tex]24x^5y^7[/tex]
The length of the rectangle is [tex]3x^2y^6[/tex]
The area is given by the product of length and width
Suppose, w is the width of the area
[tex]\therefore A=l\times w\\\Rightarrow 24x^5y^7=3x^2y^6\times w\\\\\Rightarrow w=\dfrac{24x^5y^7}{3x^2y^6}\\\\\Rightarrow w=8x^3y[/tex]
Thus, the width of the rectangle is [tex]8x^3y[/tex]

to solve the question we need to recall one of the most important theorem of circle known as two tangent theorem which states that tangents which meet at the same point are equal that is being said
FA=AI=17CH=CG=2.5since [tex]\rm BA=FA+FB[/tex] and it's given that FA and BA are 17 and 29 FB should be
[tex]\rm 29=17+FB[/tex]therefore,
[tex]FB=29-17=\boxed{12}[/tex]once again by two tangent theorem we acquire:
[tex]FB=BH=\boxed{12}[/tex]As BC=BH+CH,BC is
12+2.5[tex]\boxed{14.5}[/tex]likewise,AD=AI+DI so,
21=17+DI [AD=21(given) and AI=17 (by the theorem)]thus,
DI=21-17=[tex]\boxed{4}[/tex]By the theorem we obtain:
DI=DG=4Similarly,DC=DG+CH therefore,
DC=4+2.5=[tex]\boxed{6.5}[/tex]Now finding the Perimeter of ABCD
[tex]P_{\text{ABCD}}=\text{AB+AD+BC+DC}[/tex]substitute what we have and got
[tex]P_{\text{ABCD}}=\text{29+21+14.5+6.5}[/tex]simplify addition:

Consider the line segment PQ with endpoints P(- 3, - 2) and Q(2, 3). Which point divides the line segment directed from P to Q in the ratio of 3:2?
Answers
Answer:
(0,1) point C
Step-by-step explanation:
the line segment PQ is divided into 5 parts ( 3parts +2 parts)
Is very important that you keep the direction correct from P to Q
The point C divides the PQ into 3:2 ratio
(0, 1) is the point that divides the line segment directed from P to Q in the ration of 3 : 2.
Vectorially speaking, we determine the the location of the point that divides the line segment in the ratio of [tex]a : b[/tex].
[tex]R(x,y) = P(x,y) + \frac{a}{a+b}\cdot [Q(x,y) - P(x,y)][/tex] (1)
Where:
[tex]P(x,y)[/tex], [tex]Q(x,y)[/tex] - Endpoints.[tex]R(x,y)[/tex] - Resulting point.If we know that [tex]P(x,y) = (-3, -2)[/tex], [tex]Q(x,y) = (2, 3)[/tex], [tex]a = 3[/tex] and [tex]b = 2[/tex], then the location of the resulting point:
[tex]R(x,y) = (-3, -2) + \frac{3}{5}\cdot [(2,3)-(-3,-2)][/tex]
[tex]R(x,y) = (-3,-2) +\frac{3}{5}\cdot (5, 5)[/tex]
[tex]R(x,y) = (-3, -2) + (3,3)[/tex]
[tex]R(x,y) = (0, 1)[/tex]
(0, 1) is the point that divides the line segment directed from P to Q in the ration of 3 : 2.
