The formula of an arithmetic sequence is the following :
A geometric sequence is in the form:
3 and four sevenths bcs 25divided by seven is 3r4
Answer:
The number is 38,478
Step-by-step explanation:
* Lets explain how to find the number
- The number is 5-digit
* Ones ⇒ the last digit
* Tens
* Hundreds
* Thousands
* Ten thousand
- The ones digit is the same as the last digit of last year's calendar year
∵ The last year is 2018
∴ The last digit is 8
∴ The ones digit is 8
- The ones digit is the same as the thousands digit
∵ The ones digit is 8
∴ The thousands digit is 8
- The ten thousands digit is five less than the thousands digit
∵ The thousands digit is 8
∴ The ten thousands digit is 5 less than 8
∵ 8 - 5 = 3
∴ The ten thousands digit is 3
- The last two digits sum to 15
∵ The last two digits are ones and tens digits
∵ The ones digit is 8
∵ 15 - 8 = 7
∴ The tens digit is 7
- There is one 4 in the number
∵ The hundreds digit is empty
∴ The hundreds digit is 4
* <em>The number is 38,478</em>
<h3>Given:</h3>
<h3>Note that:</h3>
<h3>
To find:</h3>
The circumference of the circular playing field.
<h3>Solution:</h3>
We'll have to multiply 2, π and radius.
Substitute the values according to the formula.
<u>Therefore</u><u>,</u><u> </u><u>the</u><u> </u><u>circumference</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>circular</u><u> </u><u>playing</u><u> </u><u>field</u><u> </u><u>is</u><u> </u><u>47.12</u><u> </u><u>feets</u><u>.</u>
The area of an exercise aid that is textured from the information regarding Fiona is 50 inches².
<h3>How to calculate the area?</h3>
From the information given, the measures or the exercise aid is approximately 25 inches around its base. Therefore, the radius will be calculated thus:
2πr = 25
(2 × 3.142 × r) = 25
6.284r = 25
r = 25/6.284
r = 3.978 = 4
Therefore, the area will be:
= πr²
= 3.142 × 4²
= 50 inches²
