The first thing that we are going to do in passing everything to the same unit.
 We have then:
 Cube A:
 7 * (1 / 3.28) = 2.13 m
 Cube B:
 2 m
 The surface area of a cube is:
 A = 6 * L ^ 2
 Where,
 L: side
 Since cube A has a longer side (2.13m) then it will have the largest surface area.
 Answer: 
 Cube A has the larger surface area

Several different cheeses are for sale. The cheese comes in wedges
Tpy6a [65]

Answer:

39.30 cm^{2}

Step-by-step explanation:

The area of the top surface of the wedge is the same as the area of a sector.

Area of a sector = (θ/360^{o})\pir^{2}

where: θ is the central angle, and r is the radius.

Given that: central angle = 45^{o}, radius = 10 centimetre.

Area of the top surface = Area of a sector = (θ/360^{o})\pir^{2}

                                      = \frac{45^{o} }{360^{o} } x \frac{22}{7} x (10)^{2}

                                      = \frac{1}{8} x \frac{22}{7} x 100

                                      = 39.2857

                                     = 39.30 cm^{2}

The area of the top surface of the wedge is 39.30 cm^{2}.

Write a linear equation for the line with slope = - 1/4 going through the point: (0, 0)
Serjik [45]

The equation of a line is written as y =Mx + b, where m is the slope and b is the y intercept, which is the y value when x = 0.

You are told the slope is -1/4, so replace m with -1/4. You are also given the point (0,0) which means when x is 0, y is also 0, so replace b with 0.

The equation becomes y= -1/4x + 0

Because y is 0 you aren’t adding anything to the equation so you can remove it from the equation.

Answer is y = -1/4x
