Area of 1 = Length × width

Length = 11
Width = 11

11 · 11 = 121

There are 6 squares.

Multiply 121 by 6 to get the total

121 · 6 = 726

Surface Area = 726 cm²

Hello!

To find the surface area of a cube you use the equation

6  a^{2}

a is a side length

Put in the values you know

6 * 11^{2}

Square the number

6 * 121 = 726

The answer is 726cm^{2}

Hope this helps!

What is the ratio of pennies to dimes in a daller
cluponka [151]


we know that 100 pennies = 1 dollar and, 10 dimes = 1 dollar so the ratio would be;

P + nx=rx-e (solve for x)
lorasvet [3.4K]

Answer:

(p+e)/(r-n) =  x

Step-by-step explanation:

p + nx=rx-e

Add e to each side

p +e+ nx=rx-e+e

p +e+ nx=rx

Subtract nx from each side

p +e+ nx - nx=rx-nx

p+e = rx -nx

Factor out x

p+e = x(r-n)

Divide each side by (r-n)

(p+e)/(r-n) =  x(r-n)/(r-n)

(p+e)/(r-n) =  x

Help me please. This is my last question
Crazy boy [7]

Answer: D. 44

Step-by-step explanation:

Here, we need to know the concept of trigonometry.

  • Sine (sin) = Opposite/Hypotenuse = O/H
  • Cosine (cos) = Adjacent/Hypotenuse = A/H
  • Tangent (tan) = Oppostie/Adjacent = O/A

-----------------------------------------------------------------------------

Given

- The adjacent side of angle x and the hypotenuse.

- We are going to use Cosine.

<u>Solve</u>

cos (x) = 15/21

       x  = cos⁻¹ (15/21)

       x  ≈ 44

Hope this helps!! :)
