Answer:

The area of a circle can be calculated by using the formula:

A = πr²

Step-by-step explanation:

I'm assuming that you are asking about how to calculate the area of a circle, so this formula would be it, where the symbol 'π' is pi, a number which never ends, but in calculations is typically rounded to 3.14. However, on your calculator you may have a button which you can press to find the area of a circle that way.

Is(2, 5)asolutiontotheinequality 2x + 3y ≥ 20 ?

Daniel [21]

Answer:

Step-by-step explanation:

2x + 3y ≥ 20

Substitute the point (2,5) in for x and y and see the inequality is true

2(2) +3(5) ≥ 20

4 + 15 ≥ 20

19 ≥ 20

This is not true, so (2,5) is not a solution

Sonja [21]

Answer:

1/6

Step-by-step explanation:

People who answered less than 1/2 were: 2 + 1 + 3 = 6 people.

There are a total of 36 people.

People who answered their calls before the second ring were only 6/36.

When we simplify the fraction, we get 1/6.

So, the answer is 1/6.

adell [148]

I'm assuming that the lower case c and the upper case C are the same variables.

6C^2 + 2.5D - D + 2C^2 - 3D = 8C^2 - 1.5D

Which inequality represents the sentence below? The difference of a number and one and four tenths is more than nine and seventy

Marianna [84]

The inequality represents the sentence below is that the p minus 1. 4 greater-than 9.

<h3>What is the inequality equation?</h3>

Inequality equation is the equation in which the two expressions are compared with greater than, less than or other inequality signs.

Given that the difference of a number and one and four tenths is more than nine and seventy-eight hundredths.

Before solving it, first let's discuss the tenth and hundredths,

Tenth is written as the fractional part of the number 10. The value of one tenth is equal to 1/10 or 0.1.
Hundredths is written as the fractional part of the number 100. The value of one hundredth is equal to 1/100 or 0.01.

Here, the sentence given that the difference of a number and one and four tenths is more than nine and seventy-eight hundredths.

One and four tenths can be written as,

$1\dfrac{4}{10}$

Nine and seventy-eight hundredths can be written as,

$9\dfrac{78}{100}$

Let suppose the number is <em>p</em>. This difference of this number and one four tenths is more than nine and seventy-eight hundredths. Thus,

$p-1\dfrac{4}{10} > 9\dfrac{78}{100}\\p-\dfrac{14}{10} > \dfrac{978}{100}\\p-1.4 > 9.78\\$

Hence, the inequality represents the sentence below is that the p minus 1. 4 greater-than 9.
