There is no solution to this set that works for both equations. If you multiply the top equation by 2 and then add them together, the x and y numbers will cancel. This leaves you with 0 =1010, which is never true.

Part 6

Deffense [45]

Answer:

Part 1) The volume of each beam is $1,858.88\ ft^{3}$

Part 2) You can fill $26\ beams$

Part 3) Yes, the amount of sand left over is $1,669.12\ ft^{3}$

Step-by-step explanation:

Part 1) What is the total volume of each beam?

The volume of a cylinder is equal to

$V=\pi r^{2} h$

we have

$h=37\ ft$

$r=8/2=4\ ft$ ----> the radius is half the diameter

assume

$\pi=3.14$

substitute the values

$V=(3.14)(4)^{2} (37)$

$V=1,858.88\ ft^{3}$

Part 2) How many beams can you fill with this sand?

we know that

You are given a container with a 50,000 sq ft of sand for your beams

<em>Note</em> Is a 50,000 cubic foot of sand instead of 50,000 sq ft of sand

Divide the total volume of sand by the volume of each beam to obtain the number of beams

$50,000/1,858.88=26.9\ beams$

Round down

$26.9=26\ beams$

Part 3) Will you have any sand left over? If so how much?

yes

$50,000-26(1,858.88)=1,669.12\ ft^{3}$

The answer is mode as it is the only one that doesn’t need to contain numbers. The mode is the one with the most of the same thing. So in this case it’s the pizza
I hope you understand it now x

Circular fountain has 18cm base blueprints scale 3cm to 4 feet what is actual area of base after built

GuDViN [60]

$\bf \cfrac{\stackrel{model~cm}{3}}{\stackrel{actual~ft}{4}}\qquad \qquad \cfrac{\stackrel{model}{18}}{\stackrel{actual}{a}}=\cfrac{3}{4}\implies \cfrac{18\cdot 4}{3}=a$
