A carpenter is building a rectangular shed with a fixed perimeter of 54 ft. What are the dimensions of the largest shed that can be built? What is its area?
Answer:
the Largest shed dimension is 13.5 ft by 13.5 ft
Largest Area is 182.25 ft²
Step-by-step explanation:
Given that;
Perimeter = 54 ft
P = 2( L + B ) = 54ft
L + B = 54/2
L + B = 27 ft
B = 27 - L ------------Let this be equation 1
Area A = L × B
from equ 1, B = 27 - L
Area A = L × ( 27 - L)
A = 27L - L²
for Maxima or Minima
dA/dL = 0
27 - 2L = 0
27 = 2L
L = 13.5 ft
Now, d²A/dL² = -2 < 0
That is, area is maximum at L = 13.5 using second derivative test
B = 27 - L
we substitute vale of L
B = 27 - 13.5 = 13.5 ft
Therefore the Largest shed dimension = 13.5 ft by 13.5 ft
Largest Area = 13.5 × 13.5 = 182.25 ft²

Answer:
f = 6 cm
g = 8 cm
Step-by-step explanation:
ABCD f*g = 48
ABCE f*g + 1/2 (4*f) = 60
48 + 2f = 60
2f = 12
f = 6
g = 48/6 = 8

Answer:
4) d. 30%. 5) 55/21. 6) 16
Step-by-step explanation:
4) 6/20 × 100 = 30%
5) Change mixed numbers to fraction. So you're getting 58/7 - 17/3. LCM = 21
= 174 - 119 / 21
= 55 / 21
6) Change to fraction
8/3 ÷ 1/6
= 8/3 × 6/1
= 16
Movie tickets cost $6 for adults and $2 for children under the age of 12. If 175 movie tickets were sold with cash receipts of $750, how many children’s tickets were sold?
Answer:
75 child tickets and 100 adult tickets were sold.
Step-by-step explanation:
Given that adult tickets cost $ 6 and children's tickets cost $ 2, knowing that 175 tickets were sold for $ 750, to determine how many child tickets were sold the following calculation must be performed:
2 x 175 = 350
750 - 350 = 400
6 - 2 = 4
400/4 = 100
175 - 100 = 75
100 x 6 = 600
75 x 2 = 150
Therefore, 75 child tickets and 100 adult tickets were sold.

Paralell to the line y=3x + 5 and has a y-intercept of -1
Step-by-step explanation:
Everything the parallel lines has the same slope
[tex]y = mx + b[/tex]
m = slope
b = y intercept
then the equation of the line is:
[tex]y = 3x - 1[/tex]
slope of and a y-intercept of :−56
Answer:
Step-by-step explanation:
your questions may have left out what the slope is.. but.. what ever it is.. just use m = ( your number )
and plug it into this slope-intercept formula [ y = mx +b }
y = mx -56 .. just plug your slope into the variable m

Answer:
11 3/4 = y ÷ 6 1/4Step-by-step explanation:
The required equation is translated as:
11 3/4 = y ÷ 6 1/4please tell me what a term is
A term is a single mathematical expression. It can be a number, a variable, several variables that have to be multiplied or sometimes have variables with a number in front (coefficient).
y is inversely proportional to x . When y = 30 , x = 3 Work out x when y = 6
Step-by-step explanation:
yx = k, where k is a real constant.
When y = 30, x = 3.
=> k = (30)(3) = 90.
Hence when y = 6, x = k/y = (90)/(6) = 15.
In the 2006 season, Tom Brady threw for 3,529
yards. In the 2007 season, he threw for 2,806
yards. What is the percentage decrease
Answer:
59.02%
Step-by-step explanation:
SO SORRY THAT THIS IS LATE anyway what you is minus the biggest number by the smallest number which would be 3,529 - 2,806 = 723
BECAUSE 3,529 is the original number you would do 723 / 3,529 = 0.5902521
then you would times that number by 100
0.5902521 x 100 = 59.02%
