First we need to find the area of the fence, since paint covers square feet and squared units refers to area. The area of the fence is 26 x 7, which is 182 sq ft. If one gallon of paint will cover 350 sq ft, your proportion will look like this, with gallons of paint on top and square feet on the bottom.
. Cross multiply to get 350x = 182 and x = .52, just a bit over a half of a gallon of paint.
Answer: $3.60
Step-by-step explanation:
Set them up to equal each other
-7x + 2 = 9x - 14
16 = 2x
x= 8
plug in the x value into any of the two y equations
y= 9 (8) - 14
y=58
points (8, 58)
Answer:
152 cubic units
Step-by-step explanation:
Volume of a cube = L³ where;
L is the side length of a cube
For the cube of side length of 3 units
Volume of the cube = 3³
Volume of the cube = 27 cubic units
For the cube of side length of 5 units
Volume of the cube = 5³
Volume of the cube = 125 cubic units
Total volume the ice can make = (125 + 27)cubic units
Total volume the ice can make = 152 cubic units
x= 3+√5/4,3-√5/4
Step-by-step explanation:
1.In general, given ax^2+bx+c=0, there exists two solutions where:
x= -b+√b^2 - 4ac/2a, -b-√b^2-4ac/2a
2.In this case, a=4, b=-6 and c=1.
x=6+√(-6)^2-4×4/2×4, 6-√(-6)^2-4×4/2×4
3.Simplify.
x=6+2√5/8, 6-√5/8
4.Simplify solutions.
x=3+√5/4, 3-√5/4
