Answers

Given Information :

Surface area of cube = 54 sq. units

To find :

Volume

Calculation :

We know that,

[tex]\bigstar \: \boxed{\sf {Volume_{(Cube)} = (\ell)^3}} \\ [/tex]

l = length of side

Let's find out the side first. We know that,

[tex]\bigstar \: \boxed{\sf {T.S.A_{(Cube)} = 6\ell^2}} \\ [/tex]

According to the question,

[tex] \longmapsto \sf {54 = 6\ell^2 } [/tex]

[tex] \longmapsto \sf {\dfrac{54}{6} = \ell^2 } [/tex]

[tex] \longmapsto \sf {9 = \ell^2 } [/tex]

[tex] \longmapsto \sf {\sqrt{9} = \ell } [/tex]

[tex] \longmapsto \sf \red{3 \: units = \ell } [/tex]

Now, calculating volume :

[tex]\bigstar \: \boxed{\sf {Volume_{(Cube)} = (\ell)^3}} \\ [/tex]

→ Volume = l × l × l

→ Volume = 3 × 3 × 3

Volume = 27

Option B is correct.

(Don't forget to show how you got your answer please!) Find the interest rate. You may answer in decimal form or percent form.

Principal: $2,500, Time: 2 years; Interest: $450

Answers

Answer:

36%

Step-by-step explanation:

I/Pt = r to get your rate.

I = Interest amount paid in a specific time period (month, year etc.)

P = Principle amount (the money before interest)

t = Time period involved

r = Interest rate in decimal

$450 ÷ 2,500(2)=36%

the maximum load of elevator is 480 pounds. Assuming that the average mass of student is 45 pounds, and m represents the number of students in the elevator, how many students can take the elevator at the same time

Answers

we can use the equation 45m < 481

we can replace m to see where it caps.

and the cap is 10.

we can replace m to check our work

45(10) < 481

450 < 481

if you add another student, it would go over the limit.

hope this helps :D
