What is the volume of the pyramid 8ft 4ft 6ft<br><br><br> 20 POINTS
horrorfan [7]

Answer:

V= 64 ft^3

Step-by-step explanation:

The volume of a pyramide is given by the formula

V = 1/3 l*w*h

Given the l = 8  w = 4  and h = 6

V = 1/3 ( 8*4*6)

V = 1/3 ( 192)

V= 64 ft^3

1. Carl's constant rate of speed is the slope of the straight line graph.

This straight line passes through: (0,0), (5,1), (10,2) etc

We can use the slope formula with any two points to find the slope of this line.

The slope formula is m=\frac{y_2-y_1}{x_2-x_1}.

Let (x_1,y_1)=(0,0) and (x_2,y_2)=(5,1)

Then m=\frac{1-0}{5-0}, \implies m=\frac{1}{5}.

Carl's speed is \frac{1}{5} miles per minute.

But we must leave our answer in miles per hour

Hence Carl's speed is \frac{1}{5}\times 60=12  miles per hour

After 2 hours, Carl will travel 12\times 2=24 miles.

2. The given line has equation -4x+y=10

We write this in slope-intercept form by solving for y.

\implies y=4x+10

This is in the form y=mx+c, where m=4 is the slope.

When x=3,  y=4(3)+10

\implies y=12+10=22

When x=3, y=22

3. The given straight line graph that models the situation passes through:

(0,0) and (20,30).

The slope of this line is \frac{Rise}{Run}=\frac{300}{20}=15

Therefore the rate is $ 15 per ticket.

If the theater sells 150 tickets, the earnings will be: 150\times 15=2,250 dollars.

To win the game eitan has to roll a sum of 11 or more using two six-sided number cubes
ddd [48]
There are 36 total possible outcomes.
Rolling a sum of 11 or higher, there are 3 possible rolls, to make a 3/36 = 1/12 probability.
Rolling a sum of 4 there are also 3 possibilities, so the chance would be the same.
Rolling a sum of 9, there are 4 possibilities, which is a better chance.
Rolling a sum less than 5, there is 6 possibilities, which is a better chance.
Rolling greater than 5 but less than 7 means rolling a sum of 6, there are 5 chances, which is a better chance.
Rolling greater than 9 but less than 11, means rolling a 10, there are 3 possibilities, which is the same.
Rolling greater than 2 and less than 4 means rolling a 3, there are 2 possibilities, which is less.
The answers would be:
Rolling a sum of 9,
Rolling a sum less than 5
Rolling greater than 5 but less than 7
