Step-by-step explanation:
15 is the correct answer.
Pythagoras theorem is used to find the hypothenuse of a right triangle. (m2 C=90 meaning it’s a right triangle)
a^2+b^2=c^2
8^2+b^2=17^2
After finishing the equation, you get 15.
12
Working;
First evaluate the division;
4÷2=2
Work on addition;
18+2= 20
work on subtraction;
20-8=12
The cost for him to rent the machine and buy the supplies is $400 ($275 + 125), so he needs to charge $550 ($400 +150) for the job in order to make $150 profit.
Answer:
They would be the same after 10 days.
Step-by-step explanation:
In order to find this, we must first create two equations. Let x be the number of days that are rented. We'll first create an equation for the first company. Since it costs $8 per day, let 8 be the coefficient of x and 20 be the constant.
y = 8x + 20
Now, do the same with the second company.
y = 5x + 50
Now that we have these, set them equal to each other to get the answer.
8x + 20 = 5x + 50
3x + 20 = 50
3x = 30
x = 10
