Answer:
4.5
Step-by-step explanation:
Well, she runs 3
miles in 28 minutes.
42
=
28
⋅
1.5
So, her journey would just be running
1.5
times, with each time running
28
minutes.
So, she runs a total of
1.5
⋅
3
=
4.5
miles

Answer:
(5, infinitysymbol)
Step-by-step explanation:
First solve the inequality. Subtract 2 from both sides.
x + 2 > 7
x > 5
So that is one way of writing the answer and it is hopefully kind of understandable. X>5 means all the numbers greater (bigger) than 5, forever to infinity.
Interval notation is a way of writing a set or group of numbers. Interval notation uses ( ) parenthesis or [ ] square brackets. Then two numbers go inside with a comma in between. The first number is where the set of numbers start and the second number is where the set ends. You always put parenthesis around the infinity symbol or negative infinity symbol. You only use a square bracket if the inequality symbols have the "or equal to" underline under the > or <.
So x > 5 in interval notation is:
(5, infinitysymbol)
This shows that 5 is not included in the solution; and all the numbers forever bigger than five are solutions as well.
Answer:
9.8
Step-by-step explanation
basically its just x/sin55=12/sin90 bc you plug into equation a/sina= b/sinb so then you x/sin55=12
sin55*12=x x=9.8
