35 x 0.14 = 4.9
The total tip would be $4.9
Let F be the father's current age, and E be Evie's current age.
F = E + 36 this is the current relation between the ages
F + 3 = 5(E + 3) this the relationship in 3 year (hence the + 3)
Then solve by substituting one equation into another:
(E + 36) + 3 = 5(E + 3)
E + 39 = 5E + 15
24 = 4E
6 = E
Evie's current age is 6.
(D) 33 feet
<u>Explanation:</u>
Given:
Height of the tree, h = 22 feet
angle, θ = 42°
Length of the ladder, l = ?
We know:
sin θ = Perpendicular / hypotenuse
So,
Sin θ = height of the tree / length of the ladder
l = 32.84 feet ≈ 33 feet
Therefore, the length of the ladder be to reach the top of the apple tree is 33 feet.
1. Note that
2. Then the equation 
can be rewritten
3. Solve it:
Answer: x=6
1/3 divided by 1/4= 4/3
The method for dividing fractions is keep change flip.
Keep the 1/3, change the division sign to multiplication sign, flip the 1/4 to a 4/1, then solve.
