Answer:
The ramp should be 32.9 feet longer.
Step-by-step explanation:
When the ramp is at to the ground, its length can be determined by applying the appropriate trigonometric function. Let the length be represented by l, so that;
Sin θ =
Sin =
l =
=
= 33.0048
l = 33.0 feet
When the angle is reduced to , the length of the ramp would be;
Sin θ =
Sin =
l =
=
= 65.9152
l = 65.9 feet
Change in length of ramp = 65.9 - 33.0
= 32.9
The ramp should be 32.9 feet longer.
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
