Answer:
- 230°
Step-by-step explanation:
A coterminal angle is the given angle ± 360n ( where n is an integer )
Given 130°
Then a coterminal angle = 130° - 360° = - 230°
OR 130° + 360° = 490°
Answer:
A student with GPA of 2.15 worked 47.8 hours per week.
Step-by-step explanation:
To find the numbers of hours worked when the GPA is 2.15, we solve the equation when or:
which can be rewritten as (by subtracting 2.15 from both sides)
.
We solve this using the quadratic equation which says, for ,
in our case
,
therefore, we have
and since only the positive solution applies to the real word, we choose , and therefore, a student with GPA of 2.15 worked 47.8 hours per week.
In three months their money will be equal and the amount is $136.
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
Given that, the Blanco family is deciding between two lawn care services.
Evergreen charges a $49 startup fee, plus $29 per month.
Let the number of months be x.
Here, 49+29x -----(i)
Great Grass charges a $25 starup fee, plus $37 per month.
So, 25+37x ------(ii)
Both lawn-care services cost the same
Equation (i) and (ii) are equal, we get
49+29x=25+37x
37x-29x=49-25
8x=24
x=3
Now, 49+29x=$136
25+37x=$136
Therefore, in three months their money will be equal and the amount is $136.

Answer:
48
Step-by-step explanation:
Since she is making only model houses and no castles, we can exclude the number 96 from our equation. Since you want to know 86 x __ = 4,128, you need to divide. 4128/86= 48.
