Answer:

<h2>A(55) =  - 201</h2>

Step-by-step explanation:

<h3>A(n) = 15 - 4(n - 1)</h3>

Since we are finding the 55th term, n = 5 .

Substitute this value into the above formula

That's

<h3>A(55) = 15 - 4(55 - 1) \\  = 15 - 4(54) \\  = 15 - 216</h3>

We have the final answer as

<h3>A(55) =  - 201</h3>

Hope this helps you

7. What's the sum of 2/5 and 2/4?
NISA [10]

Step-by-step explanation:

2/5+2/4 (find common denominator)

The common denominator is 20

2/5 is 8/20 (multiply by 4)

2/4 is 10/20 (multiply by 5)

8/20+10/20 is 18/20

If you simplify 18/20 this would by 9/10 if you divide by 2

so the total is 18/20 or 9/10 simplified

Hope this helps!!!!

Have a nice day :)

What is the surface area of the cylinder with height 6 ft and radius 6 ft? Round your
Paul [167]

The surface area of this cylinder to the nearest thousandth is equal to 452.448 square feet.

<u>Given the following data:</u>

  • Height of cylinder = 6 ft.
  • Radius of cylinder = 6 ft.

To calculate the surface area of this cylinder to the nearest thousandth:

<h3>How to calculate surface area.</h3>

Mathematically, the surface area (SA) of a cylinder is given by this formula:

SA = 2\pi rh + 2\pi r^2

<u>Where:</u>

  • h is the height.
  • r is the radius.

Substituting the given parameters into the formula, we have;

SA = 2 \times 3.142 \times 6 \times 6  + 2 \times 3.142 \times 6^2\\\\SA = 226.224 + 226.224

SA = 452.448 square feet.

Gina is making pancakes for breakfast. Each batch of pancakes calls for 1/4 of a teaspoon of salt. Gina has 9/10 of a teaspoon o
nikitadnepr [17]

Divide the total amount she has by how much she needs per batch.


When dividing fractions, flip the second one over and then multiply straight across.


9/10 / 1/4 becomes: 9/10 x 4/1


9/10 x 4/1 = 36/10 = 3 6/10 = 3 3/5

She can make 3 more batches and have 3/5 of a teaspoon left over.
