Answer:

A

Step-by-step explanation:

The length of sides would be  A/4, B/4 and C/4 where A, B, and C are the perimeters of the three squares.

As the triangle is a right triangle,

c² = a² + b²

only answer A with sides 3, 4, and 5 will fulfil Pythagorean theorem.

B sides are 5, 4, and 6

C sides are 10, 20, and 30

D sides are 4, 6, and 7

Which equations are true?
Vlad [161]

Answer:

Step-by-step explanation:

1)4.5m+4.7=20m+47

4.5m-20m=47-4.7

-15.5m=42.2

m=-2.72

2)14+21w=7(2+3w)

  41+21w=14+21w

   21w-21w=14-41

3)49r+35=7(7r+35)

  49r+35=49r+245

 49r-49r=245-35

4)9(8h-3)=72h-27

  72h-27=72h-27

   72h-72h=-27+27

5)5.2+5.3t=10+15t

   5.3t-15t=10-5.2

    -9.7t=4.8

      t=4.8/-9.7

      t=0.49

6)6f+3.111=18f-33

  6f-18f=-33-3.111

  -12f=-36.111

     f=-36.111/-12

     f=3.01

BC = 4x + 2 AB = 8x + 8 and AC = 22 Find BC
Scilla [17]

Answer:

BC = 6.8

Step-by-step explanation:

The distance from A to B, then from B to C, is the same distance as from A to C.

Thus,

AB + BC = AC

AB = 8x + 8

BC = 4x + 2

AC = 22

AB + BC = AC

(8x + 8) + (4x + 2) = 22

Expanding the parenthesis:

8x + 8 + 4x + 2 = 22

8x + 4x + 8 + 2 = 22

12x + 12 = 22

Subtracting 12 from both sides:

12x = 10

Dividing both sides by 12:

x = 10/12 = 1.2

x = 1.2

We're looking for BC. As we know,

BC = 4x + 2

Let's now put in x = 1.2 into this equation:

BC = 4x + 2

BC = 4 * 1.2 + 2

Since 4 * 1.2 is 4.8:

BC = 4.8 + 2

BC = 6.8

Answer: BC = 6.8

A window is being replaced with tinted glass. The plan below shows the design of the window. Each unit length represents 1 foot.
Ilia_Sergeevich [38]
Let us solve for the total area. In this problem, we solve area 1 (the rectangle in the middle) and the area 2 ( the two half circle on the sides).

Solve for area 1:
Area rec = L * W = 5units * 4 units = 20 squared units

Solve for area 2:
Area cir = pi *r² = 3.14 * (2 units)² = 12.56 squared units

Total area = 20 + 12.56 = 32.56 foot²
Total cost = 32.56 foot² * ($23/foot²) = $ 748.88

Total cost is $748.88.

what is the equation of a line that passes through the point (6,1) and is perpendicular to the line whose equation is y=2x-6?
alexandr402 [8]

Answer:

y = -(1/2)x + 4

Step-by-step explanation:

Use the standard form on an equation:  y = mx + b

A line that is perpendicular has a slope that is the opposite reciprocal of the other line.  We also have a point (x, y) that is on the line, so our equation begins as..

1 = -(1/2)(6) + b           We must solve for b (  -1/2 is the opposite reciprocal of 2)

1 = -3 + b

4 = b  

so our equation is

y = -(1/2)x + 4
