Answer:

Cube a

Step-by-step explanation:

You can compare them only if they have the same units of measure.

Ft -> m:

3.28ft -------- 1m

17ft ------------ x

x=17×1/3.28=5.183m.

Thus the cube a (5.183m) has a larger size than cube b (5m).

Hence the cube a has a larger surface area.

I think it might be b. I'm super sorry if I'm wrong I tried my best :(

A pottery can make B bowls and P plates in a week according to the relation

Vilka [71]

Quadratic equations is an equation that has a standard form of a·x² + b·x + c = 0

The correct values are presented as follows;

(a) If the pottery makes 5 bowls a week, the number of plates that can be made is 18 plates

(b) The maximum number bowls produced in a week is 15 Bowls

The reason the above values are correct are as follows:

The given relation between the number of bowls, B, and plates, P, that can be made in a week is presented as follows;

2·B² + 5·B + 25·P = 525

(a) Required: The number of plates that can be made if five (5) bowls are made each week

Solution:

To find out the number of plates that can be made, the given number of bowls (5) is placed in the equation as follows;

When B = 5, we get;

2 × 5² + 5 × 5 + 25·P = 525

25·P = 525 - (2 × 5² + 5 × 5) = 450

P = 450/25 = 18

P = 18

If the pottery makes 5 bowls a week, the number of plates that can be made, P = 18 plates

(b) Required: To find the maximum number of bowls that can be produced each week

Solution:

The given relation is rewritten as follows;

2·B² + 5·B + 25·P = 525

Given that the sum of the bowls B, produced and plates, P, produced is a constant, the maximum number of bowls is produced when the minimum number of plates are made

Therefore, when no plates are made, we get;

P = 0

2·B² + 5·B + 25×0 = 525

2·B² + 5·B = 525

2·B² + 5·B - 525 = 0

Factorizing with a graphing calculator, or by the quadratic formula, gives;

Calculator: (B - 15)·(2·B + 35) = 0

Quadratic formula: B = (-5 ± √(5² - 4 × 2 × (-525)))/(2 × 2)

∴ The maximum number bowls, B = 15 or -35/2

The positive value of B is used, therefore;

The maximum number bowls produced in a week = 15 Bowls

A cricular arena is lit by 5 lights equally spaced around the perimeter of the arena. What is the measure of each angle formed b

Kitty [74]

Answer:

108°

Step-by-step explanation:

Suppose that circle with center A is a circular arena. Points B, C, D, E and F are 5 lights. These 5 points form regular pentagon (because these 5 lights are equally spaced around the perimeter of the arena).

The sum of all interior angles of pentagon can be calculated using following formula

$(n-2)\cdot 180^{\circ},\\ \\(5-2)\cdot 180^{\circ}=3\cdot 180^{\circ}=540^{\circ}$
