The way she has the equation set up, she is only selling 1 bottle of tea and x bottles of water. So, she basically forgot to put the variable in that represents the number of bottles of tea sold

the way it should be : x = # of bottles of water, and y = # of bottles of tea
1.25x + 1.49y = 100

Answer:

Step-by-step explanation:

Barbara sells iced tea for $1.49 per bottle and water for $1.25 per bottle.

She wrote an equation to find the number of drinks she need to sell to earn $100 as

1.25x + 1.49 = 100

In this equation Barbara has assumed the number of water bottle sold as x but she hasn't assumed another variable for the bottles sold of iced tea,

Therefore, Barbara should take two variables one for the number of bottles sold of water and another for the bottles sold of iced tea.

Equation should be in the form of

1.25x + 1.49y = 100

A ladder leans against a 22-feet-tall apple tree. The base of the ladder forms a 42° angle with the ground. Approximately how ta
igomit [66]

(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

sin 42^0 = \frac{22}{l} \\\\0.67 = \frac{22}{l} \\\\l = 32.84 feet

l = 32.84 feet ≈ 33 feet

Therefore, the length of the ladder be to reach the top of the apple tree is 33 feet.
