Answer:
210.25 or 210.3495409 depending on how your teacher does it
Step-by-step explanation:
Looking for circumference of the circle when it asks for perimeter
Formula for Circumference C = π x r <em>3 (cubed)</em>
The diameter is 10 so you take half of ten or 10 ÷ 2 = 5
5 x 5 x 5 = 125 (r squared equation)
125 x π = 392.6990817
Some classes ans stuff use 3.14 for pi so i'll show it that way too
125 x 3.14 = 392.5
(equation with π)
392.6990817 ÷ 2 = 196.3495409
196.3495409 + 14 = 210.3495409
(equation with 3.14)
392.5 ÷ 2 = 196.25
14 + 196.25 = 210.25
Answer:
Dd
Step-by-step explanation:
Answer:
Ms. Carger would have sent
emails in x minutes
Step-by-step explanation:
Firstly, Ms. Carger takes her 3 minutes to start up her computer and log-in to her email.
Therefore in x minutes, after starting up her computer and logging-in to her email, she would have x minutes minus the time used to start up her computer and log-in to her email. this implies she would have (x-3) minutes left for sending emails.
Since it takes 7 minutes to write and send each email, in (x-3) minutes she would be able to send only
emails.
Therefore equation to represent the number of emails she can send in x minutes is
emails
Answer:
10
Step-by-step explanation:
B/G = 4/5
8/G = 4/5 Multiply each side by 5
40/G = 4 Multiply each side by G
40 = 4G Divide each side by 4
G = 10
There are 10 girls in the class.
Check:
8/10 = 4/5
4/5 = 4/5
