High school and up plssss help. I’m doing corrections so it’s not B and can you explain it for me

Answer:

D. 216

Step-by-step explanation:

What I did was I multiply 9x9x8 and got 648. I then divide 648 by 3 and got 216. I would appreciate it if you can mark this the brainliest if you can.

The volume of the regular pyramid is V = 216 units³

The volume of a pyramid, is the product of the area of its base with the height of the pyramid, and divide by 3. We express this product with the formula V = ( 1/3) ×B×h, where B is the area of the base of the pyramid, and h is its height.

Volume of Pyramid = ( 1/3 )a²H

Given data ,

Let the volume of the pyramid be represented as V

Now , the equation will be

Let the height of the pyramid be H = 8 units

Let the side length of the pyramid a = 9 units

Now , Volume of Pyramid = ( 1/3 )a²H

On simplifying , we get

The volume of pyramid V = ( 1/3 ) ( 9 )² ( 8 )

The volume of pyramid V = ( 27 ) ( 8 )

The volume of pyramid V = 216 units³

Hence , the volume of the pyramid is 216 units³

Answer:

y=1/3x-4

Step-by-step explanation:

1. Use the slope formula to find the slope of the two coordinates.

y2-y1/x2-x1

-2--5/6--3

3/9 = 1/3

The slope is 1/3

2. Choose one of the coordinates and plug them and the slope into the point-slope formula

y-y1=m(x-x1)

y+2=1/3(x-6)

3. Distribute and simplify.

y+2=1/3x-2

y=1/3x-4

Answer: y=1/3x-4

Explanation:

Begin by finding the slope of the line. You can do this by using the given ordered pairs and plugging them into the slope formula, y^2-y^1/x^2-x^1. Plugging them would appear as -2-(-5)/6-(-3). The resulting math would be 3/9 or 1/3 when simplified. Using the slope-intercept form, we can plug in the slope to make it y=1/3x+b. Choose any ordered pair to plug into the equation. I'm going to use (-3,-5). Plugging this in would result with -5=1/3(-3)+b. Multiply 1/3 and -3 to get -5=-1+b. Add -1 to both sides to get b=-4.

Answer:

2.25 miles

Step-by-step explanation:

When driving a car time taken is 20 minutes. This is equal to 20/60 hours , 1/3 hours / 0.3 hours

When riding a bike , time taken is 45 minutes. This is 45/60 hours , 3/5 hours/ 0.75 hours

The formula for speed is : Speed = Distance covered / time taken

The statement is that the driving speed is greater than biking speed by 4.5 mph

Assuming the distance to work is x miles then;

x/ 0.3 - x/0.75 = 4.5  ------eliminate 0.3 by multiplying each term by 0.3 to get

x- 0.3/0.75 x = 1.35 -------eliminate 0.75 by multiplying each term by 0.75 to get

0.75 x - 0.3 x = 1.0125

0.45 x = 1.0125

x= 1.0125 / 0.45

x = 2.25

Question:

Show 2 ways that four people can share a 6-segment chewy fruit worm.

In each case how many segments does each person get ?

Answer:

a. [tex]Each\ Person = 1.5\ segments[/tex]

b. [tex]Each\ person = 3\ segments[/tex]

Step-by-step explanation:

Given

[tex]Segments = 6[/tex]

[tex]People = 4[/tex]

Method 1: Simply divide the number of segments by the number of people.

[tex]Each\ Person = \frac{Segments}{People}[/tex]

[tex]Each\ Person = \frac{6}{4}[/tex]

[tex]Each\ Person = 1.5[/tex]

Method 2:

Start by taking LCM of 4 and 6

[tex]4 = 2*2[/tex]

[tex]6 = 2 * 3[/tex]

[tex]LCM = 2 * 2 * 3[/tex]

[tex]LCM = 12[/tex]

This means that you divide the chewy fruit into 12 segments. This is done by cutting each segment in half.

Each person gets:

[tex]Each\ person = \frac{Segments}{People}[/tex]

[tex]Each\ person = \frac{12}{4}[/tex]

[tex]Each\ person = 3[/tex]

So, when the fruit is further divided to 12, each person gets 3 segments of the division.

Answer:

the longest side is AB

Step-by-step explanation:

The required algebraic expression is 11+0.50x which represents the total amount spent.

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers. Unknown variables, numbers, and arithmetic operators make up an algebraic expression. It contains no equality or inequality symbols.

We have been given that the fair charges are $11 to enter and $0.50 per ticket.

Let's assume variable "x" represents the cost per ticket.

According to the given situation, we can write the algebraic expression would be as:

⇒ 11 + 0.50x

Here $11 indicates the entrance charge.

Therefore, the required algebraic expression is 11+0.50x which represents the total amount spent.
