The height in feet of the tree is 111.5 ft.
<h3>How to find the height of a tree?</h3>
The height of a house is 52 ft.
A tree beside the house is 7.5 ft more than twice as tall.
The height of the tree is as follows:
let
x = height of the house
Therefore,
The height of the house = x = 52 ft
Hence,
height of the tree = 7.5 + 2x
height of the tree = 7.5 + 2(52)
height of the tree = 7.5 + 104
height of the tree = 111.5
height of the tree = 111.5 ft

Remark
Multiply both sides of the equation by 25. Then you have an equation that you have already done probably.
Step One
Multiply both sides of the equation by 25
1 * (20 - t) = 4t - (3/5) * 25 Every part of the equation must be multiplied by 25
(20 - t) = 4t - 75/5 3*25/5 = 75/5
20 - t = 4t - 15 Add t to both sides
20 - t + t =4t + t - 15 Combine like terms
20 = 5t - 15 Add 15 to both sides
20 + 15 = 5t - 15 + 15 Combine like terms
35 = 5t Divide by 5
35/5 = 5t/5 Switch sides
t = 7 Answer
Slope-intercept form is y = mx +b, where the variable m represents the slope of the line and the variable b represents the y-intercept of the line. Since we weren't given the y-intercept, one way to solve this problem is substitute the slope for the variable m and then the x and y values from the ordered pair to solve for b.
y = mx + b
y = 3x + b
-4 = 3(9) + b
Now, we can simplify by computing the multiplication on the right side of the equation.
-4 = 27 + b
Finally, we can find the value for b by subtracting 27 from both sides of the equation to get:
-31 = b
Now, we should substitute this value for b back into our equation with the slope.
y = 3x - 31
Therefore, your answer is y = 3x - 31.
Hope this helps!
Answer:
Shad's cost per use will be $ 2.80.
Step-by-step explanation:
Since Shad Yarbrough wants to consider the cost per use of a high-end desk top computer he is considering for his web site business, and the computer costs $ 1,750 and has a life expectancy of four years, if Shad feels he would use the computer three days a week, on average, to determine what is Shad's cost per use, the following calculation must be performed:
Weeks per year = 52
52 x 4 = 208
208 x 3 = 624
1750/624 = X
2.80 = X
Thus, Shad's cost per use will be $ 2.80.
