A dance floor has a perimeter of 60 meters. The dance floor is 20 meters long. Write an equation to represent the perimeter of t

Jet001 [13]

Answer:

20 meters long and 10 meters wide

Step-by-step explanation:

since the perimeter is 60 and one side of it is 20 then you multiply 20 by 2, 40, to get both sides. Then you subtract 40 from 60 leaving the other two sides as 20, meaning that if you divide 20 by 2 you can find that the width of the dance floor is 10 meters long.

Renna pushes the elevator button, but the elevator does not move. The mass limit for the elevator is 450 kg, but Renna and her l

pychu [463]

Answer:

$620-37.4p\leq 450$

Step-by-step explanation:

Let p be the number of identical packages.

We have been given that each package has a mass of 37.4 kg, so weight of p packages will be 37.4p.

The total mass of Renna and her load of identical packages is 620 kg.

We have been given that the mass limit for the elevator is 450 kg. This means that Renna can remove p packages from 620 kg such that 620 minus weight of p packages will be less than or equal to 450 kg.

We can represent this information in an inequality as:

$620-37.4p\leq 450$

Therefore, the inequality $620-37.4p\leq 450$ can be used to determine the number of packages, p, Renna could remove from the elevator to meet the mass requirement.

The High Roller, a giant ferris wheel in Las Vagas, casts a 242-foot shadow. A 6’3” tall man standing nearby casts a 2 3/4-foot

Ira Lisetskai [31]

Answer:

550ft

Step-by-step explanation:

Simple napkin math, so you know what both shadows are you need to find how tall the High Roller is we will use X for this.

$\frac{242ft}{6'3"} x \frac{x}{2'9"}$

Im not 100% I set it up right but essentially 242 divided by 2'9" and that equals 88

Take 88 and multiply that by 6'3" and you get your Height for the High Roller

What I did their was I scaled the humans height to that of the High Roller dividing it gives you a number you can use to scale the height of that human to how it should scale to the High Roller, which is why I took 88 and multiplied it by the human's height.

Hope this helped :)
