a circle with the diameter of 40 inches. what is the area?

Answers

Answer 1

Answer:

A= 1256

Step-by-step explanation:

The formula for area of a circle is [tex]A=\pi r^{2}[/tex]

1. Diameter is DOUBLE of radius, so the diameter must be divided by 2. 40/2 = 20.

2. Then, plug in the values into the area formula. A= 3.14[tex](20^{2})[/tex]

3. Solve. A= 1256. (Remember that 20 squared is 20x20)

Step-by-step explanation:

Start counting at position 0, the rightmost position has value 10⁰ = 1

The one left to that 10¹ = 10

... and so forth ...

The 6th position has value 10⁶ = 1000000, a.k.a. one million.

The place value of 3 in 553 049 270 is 1 million.

Here the number is given as 553 049 270.

We have to find the place value of 3 in given number.

What is Place value?

Place value is describe the position or place of a digit in a number.

Now,

To find the place value of 3;

Start counting at position 0, the rightmost position has value [tex]10^{0}= 1[/tex]

The position of 7, one left to 0, has value [tex]10^{1} = 10[/tex]

------ and so on.

Now, position of 3 is 6th position has value [tex]10^{6} = 1000000[/tex]

So, The place value of 3 in 553 049 270 is 1 million.

An online video streaming service offers two plans for unlimited streaming. Plan A has a one-time $25 membership fee and is $8 per month. Plan B has a $5 membership fee and is $12 per month.

Write a System of Equations that represents the 2 plans

For which months is Plan A the less expensive option? For which months is Plan B
the less expensive option?

Answers

Answer:

Plan A : f(x) = 25 + 8x

Plan B : f(x) = 5 + 12x

Plan A is better if used for more than 5 months (5 - ∞), plan B for 1 - 4 months

Step-by-step explanation:

x represents months

Plan A : f(x) = 25 + 8x

Plan B : f(x) = 5 + 12x

The equilibrium is when both of these functions have the same value

25 + 8x = 5 + 12x

4x = 20

x = 5

Now we compare these two plans before the 5 months,

e. g. when x = 2

The cost of plan A: 25 + 8x = 25 + 8 * 2 = 41$

The cost of plan B: 5 + 12x = 5 + 12 * 2 = 29$

Since 41$ > 29$, for 1-4 months plan B is a cheaper option, then after 5 months the costs of these two plans are equal and then plan A will be the cheaper aka less expensive option.
