2.47 + 7.1 = 9.57
7.1 + 2.47 = 9.57
9.57 - 2.47 = 7.1
9.57 - 7.1 = 2.47
<u>Explanation</u>
A fact family is a group of math facts using the same numbers. In the case of addition/subtraction, you use three numbers and get four facts.
In this case we are going to write two different addition facts and two different subtraction facts as follows:
2.47,9.57,and 7.1
<em><u>Addition facts</u></em>
2.47 + 7.1 = 9.57
7.1 + 2.47 = 9.57
<em><u>Subtraction</u></em>
9.57 - 2.47 = 7.1
9.57 - 7.1 = 2.47
Counting the number tabulated in the given above, it can be concluded that indeed there were 20 days in consideration. To determine how many days did they receive 19 or fewer emails, we just have to count the number less than 20. That is, 13 days out of the 20 working days.
Answer:
yes because it is just a reflection and because those little lines state they are similar
Step-by-step explanation:
Answer:
Circumference = 2 * radius * 3.14
82.14 = 2*3.14 r
r= 82.14/6.28=13.079 cm.
So the area = 3.14 r^2
3.14*13.079^2
537.129 cm ^2
