Answer:
Step-by-step explanation:
Let denote side of the square base.
Area base=Area top:
#Area of base and top is each
Given the volume as 5 cubic feet and side of base as x, height is:
Substitute the given prices to give the function for cost of material.
Top=30cents/ft, Base=10cents/ft and sides =50cents/ft:
The function for the cost of material is expressed as:
Answer:
£37.8
Step-by-step explanation:
£54 time .30 or 30% equals 16.2.
Then £54 minus £16.2 is £37.8 which is the answer.

The velocity or speed of the kayaker going north at a speed of 3 m/s and that of the current going east at a speed of 2 m/s create a resultant speed of √13 m/s. The new distance that has to be traveled by the kayaker in order to move 100 m north is calculated through the equation,
3 / √13 = 100 / x
The value of x is 120 m. The total time it will take for the kayaker to reach the destination is,
t = 120 / √13 = 33.33 s
Original
A = 6.5 x 4.8 = 31.2 m^2
Increase base by double = 6.5 x 2 = 13
increase height by 1.5 = 1.5 x 4.8 = 7.2
so
new A after increased = 13 x 7.2 = 93.6 m^2
93.6 - 31.2 = 62.4 m^2
answer
Area will increase by 62.4 m^2
Answer:
Since two points determine any line, we can graph lines using the x- and y-intercepts. To find the x-intercept, set y = 0 and solve for x. To find the y-intercept, set x = 0 and solve for y. This method of finding x- and y-intercepts will be used throughout our study of algebra because it works for any equation.
