A building is 2 ft from a 12 ft fence that surrounds the property. A worker wants to wash a window in the building 17 ft from the ground. He plans to place a ladder over the fence so it rests against the building. He decides he should place the ladder 8 ft from the fence for stability. To the nearest tenth of a foot, how long of a ladder will he need?
Using Pythagoras theorem, the ladder must be 19.7ft long.
What is Pythagoras theorem?Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“.
Perpendicular = height of the window from the ground = 17ft
Base = distance of the foot of the ladder from the base of the building = 10ft
Hypotenuse = [tex]\sqrt{perpendicular^{2} +base^{2} }[/tex]
H = [tex]\sqrt{17^{2}+10^{2} }[/tex] = 19.4ft
Length of ladder = 19.4ft

Two more than a certain number is 15 less than the product of 7/8 and the number
Final answer:
The algebraic equation derived from the statement is solved by isolating 'x' after moving terms to either side of the equation and combining like terms. The solution to the equation is x = -136, which represents the certain number in question.
Explanation:
Solving the Algebraic Equation
The question can be translated into an algebraic equation. Let's call the certain number 'x'. According to the problem, 'two more than a certain number is 15 less than the product of 7/8 and the number'. We can write this as:
x + 2 = (7/8)x - 15
To solve for x, we can start by moving all terms involving x to one side of the equation and the constant terms to the other side, aiming to isolate x:
Subtract (7/8)x from both sides to get x - (7/8)x + 2 = -15.
Combine like terms, remembering that x is the same as (8/8)x, which results in (1/8)x + 2 = -15.
Subtract 2 from both sides to get (1/8)x = -17.
Multiply both sides by 8 to find x. Therefore, x = -136.
The certain number in the equation is -136.
Customers at an ice-cream shop took a survey. The results showed that 144 customers rates the shop as being "very satisfactory." This number represented 45% of the total number of customers who took the survey. What was the total number of customers who took the survey ? explaination plz
The total number of customers who took the survey is 320 customers
let
x = total number of customers
percentage of "very satisfactory" customers = 45%
Number of "very satisfactory" customers = 144
So,
Number of "very satisfactory" customers = percentage of "very satisfactory" customers × total number of customers
144 = 45% × x
144 = 0.45 × x
144 = 0.45x
x = 144/0.45
x = 320
Therefore, the total number of customers who took the survey is 320

A sunflower in Julia Rosario's garden was 12 centimeters tall when it was first planted. Since then, it has grown approximately 0.6 meters per day. Write an equation in slope-intercept form that models this situation. How tall will her sunflower be after two weeks?
An equation in slope-intercept form models given situation is y=0.6x+20 and the length of the sunflower after two weeks is 21.2 meters.
Given that, a sunflower in Julia Rosario's garden was 12 centimetres tall when it was first planted. Since then, it has grown approximately 0.6 meters per day.
We need to write an equation in slope-intercept form that models this situation.
What is the slope-intercept form?The slope-intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept( the y-coordinate of the point where the line intersects the y-axis). The equation of the line is the equation that is satisfied by each point that lies on that line.
The slope intercept form equation for a straight line with a slope, 'm', and 'b' as the y-intercept can be given as y = mx + b.
Let y be the length of a sunflower plant and the number of days be x.
Now, y=0.6x+20
The length of the sunflower after two weeks is y=0.6×2+20
⇒y=1.2+20=21.2 meters
Therefore, an equation in slope-intercept form models given situation is y=0.6x+20 and the length of the sunflower after two weeks is 21.2 meters.
