Step-by-step explanation:
It is given that,
The height of the sail on a boat is 7 feet less than 3 times the length of its base.
Let the length of the base is x.
ATQ,
Height = (3x-7)
Area of the sail is 68 square feet.
Formula for area is given by :
x = 8 feet and x = -3.73 feet
So, length is 8 feet
Height is 3(8)-7 = 17 feet.
So, its height and the length of the base is 17 feet and 8 feet respectively.
The question is incorrect
the correct question is
A local citizen wants to fence a rectangular community garden. The length of the garden should be at least 110 ft,and the distance around should be no more than 380 ft. Write a system of inequality that model the possible dimensions of he garden. Graph the system to show all possible solutionslet
x---------------> t<span>he length of the garden
</span>y---------------> the wide of the garden
we know that
x>=110
2x+2y <=380---------------> x+y <= 190
Part A) <span>Write a system of inequality that model the possible dimensions of he garden
</span>
the answer part A) is
x>=110
x+y <= 190
Part B) <span>Graph the system to show all possible solutions
using a graph tool
see the attached figure
the solution is the triangle show in the figure
</span><span>the possible solutions of y (wide) would be between 0 and 80 ft
</span>the possible solutions of x (length) would be between 110 ft and 190 ft
3/4 < 33/40 because 30/40 < 33/40
Let, the number of student = x
Fraction of boys = 1 - 2/5 = 3/5
So, it would be: x * 3/5 = 1482
x = 1482*5 / 3
x = 7410/3
x = 2470
Thus, There are total 2470 students
Hope this helps!
Answer:
x = - 13/10
Step-by-step explanation:
4^(4x+1) = (1/64)^(2x+4)
4^(4x+1) = (1/4^3)^(2x+4)
4^(4x+1) = (4^-3)^(2x+4)
4^(4x+1) = 4^(-6x - 12)
4x + 1 = - 6x - 12
10x = - 13
x = -13/10
