The program is an illustration of loops
What are loops?Loops are program statements that are used to perform repetition
The main programThe program written in Python, where comments are used to explain each line is as follows:
#This initializes sum to 0
summ = 0
#This gets input for the first number
num = int(input())
#This is repeated while num is not -1
while num!= -1:
#This calculates the sum
summ+=num
#This gets input for the num

You need to paint your house to sell it. You can choose between two different painters, George and Henry. George will charge 90$ for the paint, and then $40 per hour. Henry will charge $120 for the paint and then $35 per hour.
After how many hours will the cost be the same?
If you estimate it will take about 10 hours to paint the room, who should you choose?
Answer:
At 6 hours the cost is the same. At 10 hours of service Henry is cheaper.
Step-by-step explanation:
This is simple. Follow my lead!
First we must create an equation for George
He charges $90 initially and then $40 per hour
So George's equation is:
[tex]y = 40x + 90[/tex]
Now let's find Henry's equation!
He charges $120 initially and then $35 per hour
So Henry's equation is:
[tex]y = 35x + 120[/tex]
1) To find when they will be the same, just set them equal to each other and solve for x.
[tex]40x + 90 = 35x + 120 \\ - 35x \\ 5x + 90 = 120 \\ - 90 \\ 5x = 30 \\ \div 5 \\ x = 6[/tex]
This means that when x = 6 or at 6 hours in the cost is the same!
2) Just solve both equations with x = 10
[tex]y = 40(10) + 90 \\ y = 400 + 90 \\ y = 490[/tex]
At 10 hours George's service costs $490!
[tex]y = 35(10) + 120 \\ y = 350 + 120 \\ y = 470[/tex]
At 10 hours Henry's service costs $470!
$470 is less than $490 so that means Henry is more cheaper!
Yay! We did it!

If we think about a right triangle, we get that the hypotenuse is 24ft or the length of the ladder. The base of the ladder is 15ft away from the building which is the leg of the right triangle. The screenshot is the diagram (my drawing isn't that good lol:))
Thus we can use cosine function with the angle between the ladder and the ground since we need to find the angle and we get
[tex]cos\alpha = \frac{15}{24}[/tex]
and [tex]\alpha = 51.3 degrees[/tex]
The angle is 51.3 degrees hope that helps!

what is the equation of the line that passes through the point (-3,-8) and has a slope of 4?
please help
Step-by-step explanation:
the easiest approach with a given point and the slope of the line is the point-slope form :
y - y1 = a(x - x1)
where "a" is the slope, and (x1, y1) is a point on the line.
so, we get
y - -8 = 4(x - -3)
y + 8 = 4(x + 3)
if we need the slope-intercept form
y = ax + b
we now simplify the point-slope form
y + 8 = 4x + 4×3 = 4x + 12
y = 4x + 4

Start by finding the area of the triangular sail.
[tex]A=\frac{1}{2}bh[/tex]
Substitute the given lengths into the equation:
[tex]A=\frac{1}{2}*5*10\\A=5*5\\A=25m^2[/tex]
Now, multiply this by 18 dollars per square meter.
[tex]25m^2(\frac{18}{1m^2})=25*18=450[/tex]
