Answer:
-11
Step-by-step explanation:
if you put the numbers of the variebles in, it would be
-6-9+9-5
Slope of a Line Passing through two points (x₁ , y₁) and (x₂ , y₂) is given by :
Given Points are (8 , 30) and (18 , 60)
here x₁ = 8 and x₂ = 18 and y₁ = 30 and y₂ = 60
We know that the form of line passing through point (x₀ , y₀) and having slope m is : y - y₀ = m(x - x₀)
Here the line passes through the point (8 , 30)
⇒ x₀ = 8 and y₀ = 30
We found Slope(m) = 3
Substituting all the values in the standard form, We get :
Equation of the line : y - 30 = 3(x - 8)
Let d be the x-intercept of this line
⇒ The line passes through the point (d , 0) as at x-intercept, y-coordinate is zero.
⇒ 0 - 30 = 3(d - 8)
⇒ 3d - 24 = -30
⇒ 3d = -30 + 24
⇒ 3d = -6
⇒ d = -2
⇒ The x - coordinate of the x-intercept of the line is -2
Answer:
2 cans
Step-by-step explanation:
Given that :
Radius of pool = 30 feets
Using the relation for the Area of a circle :
Area = pi*r^2
Thus,
Area of pool = 3.14 * 30^2
Area of pool = 3.14 * 900 = 2826feet²
Paints are sold in cans of 5 gallon
5 gallon of paint = 1500 feet²
Least number of 5 gallon can required :
2826 feet² / 1500 feet² = 1.884 cans
Hence,
Least number of 5 gallon can required = 2 cans
Answer:
0.08
Step-by-step explanation:
Well when you do a percent you wanna set up a proportion. Part over total and then percent over 100. I’m not sure if this helped but this is my advice. Remember the part over total, you might have to search for it, but when you set that up just multiply and divide and you got it!! Hope this helped (:
