Tower one, a cube with a hexagonal prism measures 15.6cm. Tower two, a cube with a cylinder measures 18.3cm. Tower 3, a hexagona
lina2011 [118]

Answer:

Tower 4 = 23.9cm

Step-by-step explanation:

Given

Tower one = 15.6 cm

Tower two = 18.3 cm

Tower 3 = 13.9 cm.

Required:

Height of the 4th tower

Represent a cube by X; a cylinder by Y and a hexagonal prism by Z

Tower one, a cube with a hexagonal prism = X + Z = 15.6

Tower two, a cube with a cylinder = X + Y = 18.3

Tower 3, a hexagonal prism with a cylinder = Z + Y = 13.9

X + Z = 15.6 ----- Equation 1

X + Y = 18.3 ----- Equation 2

Z + Y = 13.9 ----- Equation 3

Subtract equation 1 from 2

(X + Y = 18.3) - (X + Z = 15.6)

X - X + Y - Z = 18.3 -15.6

Y - Z = 18.3 -15.6

Y - Z = 2.7 ---- Equation 4

Add Equation 4 to Equation 3

(Y - Z = 2.7) + (Z + Y = 13.9)

Y + Y - Z + Z = 2.7+ 13.9

2Y  = 2.7+ 13.9

2Y  = 16.6

Divide both sides by 2

\frac{2Y}{2}  = \frac{16.6}{2}

Y  = \frac{16.6}{2}

Y  = 8.3cm

Substitute Y  = 8.3cm in Equation 2 and 3

X + Y = 18.3 ----- Equation 2

X + 8.3 = 18.3

Subtract 8.3 from both sides

X + 8.3 - 8.3 = 18.3 - 8.3

X = 18.3 - 8.3

X = 10cm

Z + Y = 13.9 ----- Equation 3

Z + 8.3 = 13.9

Subtract 8.3 from both sides

Z + 8.3 - 8.3 = 13.9 - 8.3

Z = 13.9 - 8.3

Z = 5.6cm

So, we have that

X = 10cm

Y  = 8.3cm

Z = 5.6cm

The question states that the 4th tower is made up of the three shapes;

This implies that;

Tower 4 = X + Y + Z

Tower 4 = 10cm + 8.3cm + 5.6cm

Tower 4 = 23.9cm

The height of the 4th tower is 23.9cm

Find the equation of a line that passes through the point (3,1) and has a gradient of -3. Leave your answer in the form y = m x
Bingel [31]

Answer:

y = (-3)\, x + 10.

Step-by-step explanation:

The question requires that the equation should be in the slope-intercept form y = m \, x + c. The m and c in this equation are constants. In particular:

  • m\! would represent the slope of this line (also known as the gradient of this line,) whereas
  • c would be the y-intercept of this line.

The question states that the slope of this line is (-3). Therefore, m = -3. Thus, the equation for this line should be in the form y = (-3)\, x + c.

The value of constant c could be found using the other piece of information: the point (3,\, 1) is in this line. In other words, the solution \text{$x = 3$ and $y = 1$} should satisfy the equation y = (-3)\, x + c.

Substitute \text{$x = 3$ and $y = 1$} into the equation y = (-3)\, x + c and solve for c:

1 = (-3) \times 3 + c.

1 = -9 + c.

c = 10.

Hence, y = (-3) \, x + 10 would be the slope-intercept form of the equation of this line.
