Find the area of each figure. Round to the nearest tenth if necessary

Mathematics
1 answer:
KatRina [158]3 years ago
3 0

Answer:

c. 952.4 in²

Step-by-step explanation:

The figure can be decomposed into a square, a trapezoid and a semicircle

Find the area of each to determine the area of the figure.

✔️Area of square = s²

s = 13 in

Area of square = 13² = 169 in²

✔️Area of trapezoid = ½(a + b)h

a = 13 in

b = 30 in

h = 20 in

Area of trapezoid = ½(13 + 30)20

= 430 in²

✔️Area of semicircle = ½(πr²)

r = ½(30) = 15 in

Area = ½(π*15²)

Area ≈ 353.4 in²

✅Area of the figure = 169 + 430 + 353.4

= 952.4 in²

A the rent all together is
450 + 60 + 40 + 80 = 630
b the rent alltogether would be
500 + 50 + 40 + 70 = 660
the rent for c would cost

640 including everything
and the rent for d would be
475 + 50 + 40 + 35 = 60
so the answer would be D

What is the answer to this system of equations? 2x - 3y= 21 and -6x + 2y = 7.
allsm [11]

answer:

x = - 9/2

y = -10

Step-by-step explanation:

make both equations look like y =

2x-3y=21 -> -3y= -2x+21 -> y = (-2x+21)/-3 -> y = 2/3x - 7

-6x + 2y = 7 -> 2y = 6x + 7 -> y = 3x + 7/2

now make the equations equal to each other (since they both equal y)

get x

2/3x - 7 = 3x + 7/2

-7 -7/2 = 3x - 2/3x

-14/2 -7/2 = 9/3x - 2/3x

-21/2 = 7/3x

(3/7) -21/2 = x

x = (3/7) -21/2

x = - 63/14

x = - 9/2

put it back in an equation to get y

y = 3x + 7/2

y = 3(-9/2) + 7/2

y = -27/2 + 7/2

y = -20/2

y = - 10

A system of two linear equations is consistent and dependent. What is true about the graph of the equations?
steposvetlana [31]

Answer:

The best answer is " The lines are the same " ⇒ A

Step-by-step explanation:

A system of two linear equations can have:

  • One solution ⇒ 2 intersected lines at a point
  • An infinite number of solutions ⇒ same line
  • No solution ⇒ 2 parallel lines

If a system has at least one solution, it is called consistent

  • If a consistent system has exactly one solution, then it is called independent. they are represented by two intersected lines at a point
  • If a consistent system has an infinite number of solutions, then it is called dependent. They are represented by the same line

If a system has no solution, then it is called inconsistent. they represented by two parallel lines

Let us use these facts above to solve our question

∵ A system of two linear equations is consistent and dependent

∴ The system has an infinite number of solutions

∴ The system represented graphically by the same line

∴ The best answer is " The lines are the same "
