Answer:
She earns 5.5 dollars per hour at the library
Step-by-step explanation:
I am going to assume that the questions is "how much she earns per hour at the library?"
Let's call x the amount of dollars earn by hour at the library. We know that she worked for 6 hours, thus she made 6x dollars.
Later her grandma gave her 20 dollars and she has now 53 dollars.
Let's write the equation and solve it
Amount earned + Amount given by her grandma = 53

Thus, based on this information we would have that Kia earns 5.5 dollars per hour.

Answer:
40.4 ft
Step-by-step explanation:
Let the part that broke away be represented as "x"
Thus, the digram makes a right triangle shape.
The closest total length of tree before the storm = x + 14 ft
Apply trigonometric function to find x.
Reference angle = 58°
Side adjacent to reference angle = 14 ft
Hypotenuse = x
Apply CAH, which is:
Cos 58 = adj/hyp
Cos 58 = 14/x
x * Cos 58 = 14
x = 14/Cos 58
x = 26.4191188 ≈ 26.4 ft
✔️closest total length of tree before the storm = x + 14 ft = 26.4 + 14 = 40.4 ft
Answer:
Step-by-step explanation:
y intercept
To find the y intercept, make x = 0
2(0) + y = - 6 zero times anything is 0
0 + y = -6
The y intercept is (0,-6)
x intercept
The x intercept happens when y = 0
2x + 0 = -6 zero added to anything = whatever you started with.
2x = - 6 Divide by 2
2x/2 = -6/2 Do the division
x = - 3
The x intercept = (-3,0)
