Answer:
Bess has been keeping track of the storm for 14 hours.
Step-by-step explanation:
The tropical storm has been moving at 15 miles per hour.
Bess recorded that the storm moved 135 miles yesterday and 75 miles today. Total distance covered by storm is

The relationship between distance speed and time is defined as




Therefore, Bess has been keeping track of the storm for 14 hours.
Example 0.777777
x = 0.77
10(x = 0.77) ----(10 because it is repeating by the tenth digit. if repeating by 2 digits like 0.2828, you'll multiply by 100)
10x = 7.77
-(x = 0.77)
9x = 7.00
x = 7/9
Answer:
Therefore the two values required are 2.08 and -11.08.
Step-by-step explanation:
i) f(x) =
+ 10x - 12 is a quadratic equation and a quadratic equation will have two roots whose values when substituted in to the given quadratic equation will give the value.
ii) The question is therefore essentially asking us to find the roots of the given quadratic equation.
This can be done by equating the given quadratic equation to zero and then solving the equation for its roots.
∴
+ 10x -12 = 0 ⇒ x = (-10 ±
) ÷ 2
= (-10 ± 12.166)÷2 = 2.08, -11.08
Therefore the two values required are 2.08 and -11.08
22' is 22 minutes
there are 60 minutes in 1 degree, how many in 22? well, the short answer is you divide it by 60, or 22/60 0.37 or thereabouts, so that makes it
121.037 degrees and 36''
36'' is 36 seconds, there are 60 seconds in 1 minute, so in short, just divide it by 60 as well, so 36/60 or 0.6 minutes
so, let us revise above some
121 degrees 22' and 36''
22' and 36'' is 22.6' because 36'' is 0.6'
how much is 22.6' in degrees? well 22.6/60
or about .38
so. 121° 22' 36'' will be 121.38° approximately
