Answer:

  6300 m³

Step-by-step explanation:

The volume of the pyramid is given by the formula ...

  V = 1/3s²h

where s is the side length of the square base, and h is the height.

  V = 1/3(30 m)²(21 m) = 6300 m³

The approximate volume of the pyramid is 6300 m³.

Answer:

D.

d = 3t; 90 mi

Step-by-step explanation:

Bicycling A bicyclist traveled at a constant speed during a timed practice period. Write a proportion to find the distance the cyclist traveled in 30 min.

elapsed time    distance

10 min               3 mi

25 min               7.5 mi

Graph it. :)

Start at (0,0), then at 10 min. on the x-axis, go 3 spaces up on the y-axis and plot a point. Do the same for 25 min. and 7.5 miles. Draw a line through all of those points, and see where the line hits on the y-axis when the x-axis is at 30 min. :)

If two things vary directly it means their ratio is a constant.  Therefore from the formula rt=d. r=d/t,  r=3/10 or 7.5/25  which reduces to 3/10.  This is the constant speed,the lable is mi/min.  Now use  (d/30)=(3/10)  and solve for d.  Cross multiply and 10d=90, or d=9 mi

Using the information given, the distance formular = 0.3t ; distance covered in 30 minutes = 9 miles

Since the speed is constant :

We could use either of distance and elapsed time values to create an equation :

Elaspsed time - - - - Distance

10 minutes _____ 3 miles

Recall :

Distance covered = speed × time

Distance covered = speed × time Speed = distance / time

Speed of bicyclist is thus :

(3 miles / 10 minutes) = speed

Speed = 0.3 miles per minute

Hence,

Distance = 0.3 × time

For a travel time of 30 minutes ;

Distance covered = 0.3 × 30 = 9 miles

Hence, distance formular = 0.3t ; distance covered in 30 minutes = 9 miles

Answer:

The probability that can afford to spend between $800 and $900

P(800≤X≤900) = 0.6826

The percentage of that can afford to spend between $800 and $900

P(800≤X≤900) = 68 percentage

Step-by-step explanation:

Step(i):-

Given that the mean of the Normal distribution = $850

Given that the standard deviation of the Normal distribution =  $50

Let 'X' be a random variable in a normal distribution

Let x₁ = 800

[tex]z_{1} = \frac{x_{1}-mean }{S.D} = \frac{800-850}{50} = -1[/tex]

Let x₂ =850

[tex]z_{2} = \frac{x_{2}-mean }{S.D} = \frac{900-850}{50} = 1[/tex]

Step(ii):-

The probability that can afford to spend between $800 and $900

P(800≤X≤900) = P(-1≤Z≤1)

                         = P(Z≤1) - P(Z≤-1)

                        = 0.5 + A(1) - (0.5 - A(-1))

                        = A(1) +A(-1)

                       = 2× A(1)       (∵ A(-1) =A(1)

                      = 2 × 0.3413

                      = 0.6826

The percentage of that can afford to spend between $800 and $900

P(800≤X≤900) = 68 percentage

Step-by-step explanation:

Answer:

- 2

Step-by-step explanation:

let the number be n then 10 less than the square is n² - 10 and equating

n² - 10 = 3n ( subtract 3n from both sides )

n² - 3n - 10 = 0 ← in standard form

(n - 5)(n + 2) = 0 ← in factored form

Equate each factor to zero and solve for n

n - 5 = 0 ⇒ n = 5

n + 2 = 0 ⇒ n = - 2

The negative solution is - 2

Answer:

23.13m^2

Step-by-step explanation:

We'll use 3.14 for pi as instructed.

We can rearrange the figure to one square and 2 full circles.

Area of the square is 3m*3m = 9m^2

Area of a single full circle is pi*1.5m*1.5m = pi*2.25m^2 = 3.14*2.25m^2 = 7.065m^2

Full area = 9m^2 + 2*7.065m^2 = 9m^2 + 14.13m^2 = 23.13m^2

Answer:

23.14

Step-by-step explanation:

tto find the area of a circle itz A=πr

A=π1.5=7.07

3x3=9

7.07+7.07+9=23.14
