To calculate the volume of this pyramid, you first need to find the volume of the triangular base. The formula for the area of a triangle is bh/2, where b is the length of the base and h is the length of the height. In this case, 3*4/2=6. Now, you need to multiply by the height of the pyramid and divide by 3 to get 6*3/3=6 cubic inches. Hope this helps!

Lin says that the inequalities h>150 and h<160 describe her height in centimeters. what do the inequalities tell us about her height?
Answers
Answer:
Her height is in between 150 and 160
Step-by-step explanation:
Given
h > 150
h < 160
Required
What do these represent?
First, the inequalities need to be combined.
If h < 160, then this means that 160 > h.
So, h > 150 and 160 > h can be combined to form an inequality in the following form;
160 > h > 150
This.meeans 160 is greater than h and h is greater than 150.
If this is related to her height, it means 160 is greater than her height and her height is greater than 150;
In other words, her height is in between 150 and 160

There are 8 baseball players in the dugout for practice. Each player shakes hands with each of the other player ONLY ONCE.
How many handshakes are there?
Answers
Explanation:
There are 8 players. For each player, there are 7 people to shake hands with. So we have 8*7 = 56 handshakes so far; however, we double count since the sequence AB is the same as BA (where A and B are player names). Order does not matter when it comes to shaking hands. So we have to divide by 2 to fix the double count. We go from 56 to 56/2 = 28. There are 28 different combinations.
You can use the formula [tex]_nC_r = \frac{n!}{r!(n-r)!}[/tex] with n = 8 and r = 2, but the formula is a bit confusing to be honest if you aren't familiar with it. The exclamation marks indicate factorials.
Extra info: The value 28 can be found in Pascals triangle. Look at the row that starts with 1, 8, ... then note how 28 is in the third slot. Keep in mind that you start at r = 0 and count up by 1. So r = 2 corresponds to the third slot.

The circumference of a circle is the distance around a circle. It is the curved line that goes round the circle. The question wants us to find the circumference of the aluminium surrounding the circular pool.
circumference of a circle = 2πr
circumference of a circle = 2 × 3.14 × 15
circumference of a circle = 30 × 3.14
circumference of a circle = 94.2 ft
The length of aluminium surrounding the pool is 94.20 ft.

Answers
The two expressions are not equivalent to each other at r =2 and r = 5.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Use r = 2 and r = 5 to determine if the two expressions are equivalent.
r + 4(2 + r) – 12 8 + 2r – 6
First put r = 2 in both the expressions:-
E1 = 2 + 4 ( 2 + 2 ) -12
E1 =6
E2 = 8 + ( 2 x 2 ) - 6
E2 = 6
Secondly, put r = 5 in both the expressions.
E1 = 2 + 4 ( 2 + 5 ) - 12
E1 = 30
E2 = 8 + ( 2 x 5 ) -6
E2 = 12
The two expressions are not equivalent at r = 2 and r =5.

Ileana buys a large circular pizza that is divided
into eight equal slices. She measures along the
outer edge of the crust from one piece and finds it
to be 5 1/2 inches. What is the diameter of the pizza
to the nearest inch?
- 4 inches
- 7 inches
- 8 inches
- 14 inches
Answers
Answer:
14
Step-by-step explanation:
the edge of one slice of pizza is 5.5 and there are eight slices so i multiplied 5.5 by eight to get the circumference
the circumference is 44 so i divided that by pi to get the diameter which was 14 after you round
if your more of a numbers/formula person this might be more helpful:
circumference: 5.5 x 8 = 44
formula for diameter is [tex]d=\frac{C}{\pi }[/tex]
so, [tex]d=\frac{44}{\pi }[/tex]
[tex]d=14[/tex]
The diameter of the pizza is 14 inches.
Given that the pizza is divided into 8 equal slices and one of the outer edges measures 5 1/2 inches.
When need to find the diameter of the pizza.
What is the formula to find the circumference of the circle?The formula to find the circumference of the circle is 2πr.
Since a pizza is divided into 8 equal parts.
So, the circumference of 1 part=2πr/8=πr/4
πr/4=5.5 inches.
⇒πr=22
⇒r=7 inches.
Then, diameter=14 inches.
Therefore, the diameter of the pizza is 14 inches.

3.Can we multiply a 2x3 matrix by a 3x2 matrix? If yes, what dimensions will the product matrix AB have ?
Answers
Answer:
Yes, the dimensions will be 2x2
Step-by-step explanation:
When multiplying matrices you have AxB by CxD. You can only multiply matrices if the inner number is the same.
Ex. 2x3 by 3x2 or QxD by DxW
The dimensions of the result will depend on the outer numbers.
Ex. 2x3 by 3x2 has a 2x2 result or QxD by DxW has a QxW result
Yes, you can multiply a 2x3 matrix by a 3x2 matrix. The result will be a 2x2 matrix because the number of rows in the first matrix and the number of columns in the second matrix define the dimensions of the product matrix.
Explanation:Yes, it is possible to multiply a 2x3 matrix by a 3x2 matrix. When multiplying matrices, the number of columns in the first matrix must be the same as the number of rows in the second matrix. Therefore, in this case, where we have a 2x3 matrix and a 3x2 matrix, the 3 columns in the first matrix and the 3 rows in the second matrix make multiplication possible.
The resulting product from the multiplication of these two matrices will be a new matrix whose dimensions are determined by the number of rows in the first matrix and the number of columns in the second matrix. In this case, as the first matrix has 2 rows and the second matrix has 2 columns, the resulting matrix will have dimensions of 2x2.

A circle has the equation x2−12x+27=−y2+8y.
What is the equation of the circle in standard form, the location of its center, and the length of its radius?
The equation of the circle is (x−6)2+(y−4)2=25; the center is at (6,4), and the radius is 5 units.
The equation of the circle is (x−6)2+(y−4)2=5; the center is at (6,4), and the radius is 5–√ units.
The equation of the circle is (x−6)2+(y−4)2=5; the center is at (−6,−4), and the radius is 5–√ units.
The equation of the circle is (x−6)2+(y−4)2=25; the center is at (−6,−4), and the radius is 5 units.
Answers
Answer:
It's the first option.
Step-by-step explanation:
x^2 - 12x + 27 = - y^2 + 8y
x^2 - 12x + y^2 - 8y = -27 Completing the squares:
(x - 6)^2 - 36 + (y - 4)^2 - 16 = -27
(x - 6)^2 + (y - 4)^2 = -27 + 36 + 16
(x- 6)^2 + (y - 4)^2 = 25 is the standard equation.
The center is at (6, 4) and the radius is 5 units.
Answer:
first option
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Given
x² - 12x + 27 = - y² + 8y ( subtract - y² + 8y from both sides )
x² - 12x + y² - 8y + 27 = 0 ( subtract 27 from both sides )
x² - 12x + y² - 8y = - 27
Using the method of completing the square on both the x and y terms
add ( half the coefficient of the x/ y term )² to both sides
x² + 2(- 6)x + 36 + y² + 2(- 4)y + 16 = - 27 + 36 + 16
(x - 6)² + (y - 4)² = 25 ← in standard form
with centre = (6, 4 ) and r² = 25 ⇒ r = [tex]\sqrt{25}[/tex] = 5 → first option

An Ice Hockey rink is a rectangle with a perimeter of 174 meters. The length is 9 meters more than twice the width. What equation describes this problem? (Remember that the perimeter is twice the length plus twice the width)
Answers
Answer:
Let width be x metres
so, length is "9 metres more than twice the width" --> 9+2x
So, perimeter is x + x + (9+2x) + (9+2x) = 174
6x + 18 = 174
6x = 156
x = 156/6
x = 26m
width = 26m
length is therefore 9+2(26) --> 9+52 --> 61m
