Answer:
4000 [tex]m^{3}[/tex]
Step-by-step explanation:
V = 1/3(Bh) where B is the area of the base and h is the height of the pyramid
B = 20(20) = 400 h = 30
V = 1/3(400)(30) = 4000 [tex]m^{3}[/tex]

Lisa is planning for a party. She receives quotes from two party planners. Choice A quotes $18 per guest, plus $100 for renting the party hall. Choice B quotes $15 per guest, plus $160 for renting the party hall. Which inequality represents the number of guests Lisa can invite, if choice A were to cost less than choice B?
Answer:
x<20
Step-by-step explanation:
Building linear functions for each situation, the inequality is:
[tex]18x + 100 < 15x + 160[/tex]
------------------
Choice A:
$18 per guest.$100 for renting.Thus, the cost of inviting x guests is given by:
[tex]C_a(x) = 18x + 100[/tex]
Choice B:
$15 per guest.$160 for renting.Thus, the cost of inviting x guests is given by:
[tex]C_b(x) = 15x + 160[/tex]
A cost less than B, thus, the inequality is:
[tex]C_a(x) < C_b(x)[/tex]
[tex]18x + 100 < 15x + 160[/tex]

The PTA wants to cover the wet areas of the trail with wood chips. They find that one bag of wood chips covers a 3 1 2 -yard section of the trail. If there is a wet section of the trail that is approximately 50 1 4 yards long, how many bags of wood chips are needed to cover the wet section of the trail?
Answer: 14 5/14 bags of woods
Step-by-step explanation:
Since one bag of wood chips covers a 3 1/2 yard section of the trail and the section of the trail is 50 1/4 yards long, the number of bags of wood chips that are needed to cover the wet section of the trail will be calculated by dividing the wet section of the trail by 3 1/2. This will be:
= 50 1/4 ÷ 3 1/2
= 201/4 ÷ 7/2
= 201/4 × 2/7
= 402/28
= 201/14
= 14 5/14 bags of woods

The blue figure is a dilation image of the black figure. The origin is the center of dilation. Tell whether the dilation is an enlargement or a reduction. Then find the scale factor of the dilation.
Answer: Reduction, 1/5
Because the image is smaller than the pre-image, it would be a reduction. Then you would count the length of one side of the Images. The length of the pre-image is 20 and the new image is 4. Then you would make a ratio of the new image to the pre-image which is 4/20, which simplifies to 1/5.
Hope this helps!
The scale factor of the dilation will be 1/4.
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
The blue figure is a dilation image of the black figure.
And, The origin is the center of dilation.
Now,
Since, The blue figure is a dilation image of the black figure.
And, The origin is the center of dilation.
Here, The length of black figure = 16 units
And, The length of blue figure = 4 units
So, The scale factor of the dilation = 4/16
= 1/4

A car requires 45 liters of petrol to travel a distance of 330 km.
1) the distance that the car can travel on 85 liters of petrol
2) the amount of petrol that the car owner has to pay to travel a distance of 990km if a liter of petrol costs $ 2.25.
Answer:
1) The car can travel 623.3 km with 85 liters of petrol.
2) The car owner has to pay $303.8.
Step-by-step explanation:
1) The distance traveled with 85 L of petrol can be found as follows:
[tex] d = \frac{330 km}{45 L}*85 L = 623.3 km [/tex]
Hence, the car can travel around 623 km with 85 liters of petrol.
2) If the liter of petrol costs $2.25, then the amount of petrol that the car owner has to pay to travel a distance of 990 km is:
[tex]x = \frac{\$ 2.25}{1 L}*\frac{45 L}{330 km}*990 km = \$ 303.8[/tex]
Therefore, the car owner has to pay $303.8.

Passes through (-6, -1) and parallel to. x - y = 4
what is the equation of the line?
Answer:
y = x + 5
Step-by-step explanation:
1) First, find the slope of the line [tex]x-y = 4[/tex]. We can do this by setting it up in slope-intercept form, represented by the equation [tex]y = mx + b[/tex]. Whatever [tex]m[/tex] or the coefficient of the x-term is will be the slope. Isolate y in the equation:
[tex]x-y = 4\\-y = -x+4\\y = x -4[/tex]
So, the slope of the given equation is 1. Parallel lines share the same slope, thus the slope of the new line will be 1 as well.
2) Now, use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] to write the equation of the line in point-slope form. Substitute values for [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] in the formula.
Since [tex]m[/tex] is the slope, substitute 1 for it. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line passes through, substitute the x and y values of (-6, -1) into those places as well. Then, isolate y in the resulting equation to put the equation in slope-intercept form and find the answer:
[tex]y-(-1) = 1 (x-(-6))\\y + 1 = 1 (x + 6)\\y + 1 = x + 6\\y = x + 5[/tex]
