PLEASE HELP WILL MARK BRAINLIEST
ANTONII [103]

Answer:

8 lb of flounder at $2.50/lb

4 lb of shrimp at $5.00/lb

Step-by-step explanation:

Let A be the pounds of shrimp

Let B be the pounds of flounder

Let C be the cost per pound of flounder

A + B = 12

A = 12 - B

        BC = 20

    A(2C) = 20

BC =  A(2C)

BC =  (12 - B)(2C)

BC =  24C - 2BC

3BC =  24C

  3B =  24

    B = 8 lb

A + 8 = 12

    A = 4 lb

5. A ball is thrown upward with an initial velocity of 50 feet per second. The
dangina [55]

Answer:

SEE BELOW IN BOLD.

Step-by-step explanation:

a.

h = -16t^2 + 50t

h = 20 t

When the height is the same:

-16t^2 + 50t = 20t

-16t^2  + 30t = 0

t(-16t + 30) = 0

t = 0 or  -16t + 30 = 0, so:

t = 0 or -30/-16 = 1.875

So the answer is 1.88 seconds to the nearest hundredth.

b.

For the ball

h = -16t^2 + 50t

Finding the derivative and equating to zero:

dh/dt = -32t + 50 = 0

t = -50/-32 = 1.563

Maximum height after 1.56 seconds to nearest hundredth

c.

When the ball hits the ground h = 0 so

-16t^2 + 50t = 0

-16t(t - 50/16)= 0

T = 3.13 SECONDS TO THE NEAREST HUNDERDTH

Find the area of the triangle <br>answer in digital format only ​
IceJOKER [234]

Answer:

33

Step-by-step explanation:

Assume that each cell on the grid represents one unit. One can use the formula, (A=\frac{(base)(hieght)}{2}) to find the area of the triangle. One can see that the base of the triangle is, (11), and the height is (6). Substitute in the given values and solve for the area,

A=\frac{(11)*(6)}{2}

A=\frac{66}{2}

A=33
