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?
Answers
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

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?
Answers
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.

Answers
The average rate of change for a function between two points is the slope of the secant line that contains the two points.
f(2)=2(2)^+10=18
f(5)=2(5)^+10=60
Therefore the two points are (2,18) and (5,60)
Use the slope formula:
m=y1-y2/x1-x2
where (x1,y1) and (x2,y2) are the coordinates of the given points.

How many solutions will this system of equations have?
y = -3.5x - 3.5
y = -3.5x + 3.5
Answers
Set equations equal to each other
-3.5x - 3.5 = -3.5x + 3.5
The -3.5x on both sides of the equation cancels out, leaving
-3.5 = 3.5
But -3.5 does NOT equal 3.5, so the solution to the system of equations is false. This means that there are no solutions.

Tyree and four friends go to the movies. Each person buys a movie ticket for $7, a snack for $5, and a drink for $2. Write an expression for the total cost of the trip to the movies. Then find the total cost.
Answers
Answer:
Tyree and all of his friends get 1 ticket for $7. Next they all get 1 snack for $5. Then they all get a drink for $2. So:
1=7
1=5
1=2
Then you take each person (which there are five of then) and you times all five people by 7, 5, 2.
5 x 7=35
5 x 5=25
5 x 2=10
After that you add it all together:
35 plus 25=60
60 plus 10=70

Answer:
Im not sure if it ment, Tyree and four friends go to the movies. Each person buys a movie ticket for $7, a snack for $5 (meaning only one snack), and a drink for $2. (Meaning only one drink) or if it ment Tyree and four friends go to the movies. Each person buys a movie ticket for $7, a snack for $5 (meaning everyone got a snack), and a drink for $2(meaning everyone got a drink). So i did the math for both of them, if they only got 5 tickets, one snack, and one drink, it would be 42 (the math problem is 35 + 2 + 5). if they got 5 tickets, 5 snacks, and 5 drinks, it would be 70(the math problem is 35 + 25 + 10).

y is inversely proportional to x . When y = 30 , x = 3 Work out x when y = 6
Answers
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.
