We have been given an equation 
that represents umber of walls, w, that Joe can paint in t hours. We are asked to find the number of hours it will take Joe yo paint 7 walls.
To solve our given problem, we will substitute 
in our given equation as:
Let us solve for t.
Therefore, it will take 
hours Joe to paint 7 walls.
Answer:
The cross multiplication would be 10(350) = 22(x).
Step-by-step explanation:
We would first convert meters to centimeters. There are 100 cm in a meter; this means 3.5 m = 3.5(100) = 350 cm.
The ratio of the height to base of the model is 10/22. The ratio of the playhouse would then be x/350. This gives us
10/22 = x/350
Cross multiplying, we would have 10(350) = 22(x).
The answer is B for that question.
Answer: d. 2 divided by cot 40 degrees
Step-by-step explanation: in this right triangle, we are given an angle and the adjacent side of the angle. now we have to find for the length of the opposite side. the formula that relates these 3 variables is the tan function which states that:
tan θ = opposite side / adjacent side
where opposite side is the height of the sail
substituting the values into the formula:
tan (40) = height / 2
rearranging in terms of height:
height = 2 * tan (40)
since tan θ = 1 / cot θ, therefore:
height = 2 / cot (40)

Answer:
12 days
Step-by-step explanation:
If they set a side $14 daily, they will need
Since there's no half day, therefore, the number of days is 12
