Answer:

Smallest surface area is of Cuboid B i.e 440 cm²

So, The company will choose cuboid B

Step-by-step explanation:

We need to find the surface area of all cuboids.

Surface Area of Cuboid A:

Length = 6

Breadth = 25

Height = 4

The formula used is: [tex]Surface \ Area \ of \ Cuboid=2((Length\times Breadth)(Breadth \times Height)+(Length \times Height)[/tex]

Putting values and finding surface area:

[tex]Surface \ Area \ of \ Cuboid=2((Length\times Breadth)(Breadth \times Height)+(Length \times Height)\\Surface \ Area \ of \ Cuboid=2((6 \times 25)+(25 \times 4)+(6 \times 4))\\Surface \ Area \ of \ Cuboid=2(150+100+24)\\Surface \ Area \ of \ Cuboid=2(274)\\Surface \ Area \ of \ Cuboid=548\: cm^2[/tex]

So, Surface Area of Cuboid A = 548 cm²

Surface Area of Cuboid B:

Length = 10

Breadth = 6

Height = 10

The formula used is: [tex]Surface \ Area \ of \ Cuboid=2((Length\times Breadth)(Breadth \times Height)+(Length \times Height)[/tex]

Putting values and finding surface area:

[tex]Surface \ Area \ of \ Cuboid=2((Length\times Breadth)(Breadth \times Height)+(Length \times Height)\\Surface \ Area \ of \ Cuboid=2(10 \times 6)+(6 \times 10)+(10 \times 10))\\Surface \ Area \ of \ Cuboid=2(60+60+100)\\Surface \ Area \ of \ Cuboid=2(220)\\Surface \ Area \ of \ Cuboid=440\: cm^2[/tex]

So, Surface Area of Cuboid B = 440 cm²

Surface Area of Cuboid C:

Length = 2

Breadth = 20

Height = 15

The formula used is: [tex]Surface \ Area \ of \ Cuboid=2((Length\times Breadth)(Breadth \times Height)+(Length \times Height)[/tex]

Putting values and finding surface area:

[tex]Surface \ Area \ of \ Cuboid=2((Length\times Breadth)(Breadth \times Height)+(Length \times Height)\\Surface \ Area \ of \ Cuboid=2((2 \times 20)+(20 \times 15)+(2 \times 15))\\Surface \ Area \ of \ Cuboid=2(40+300+30)\\Surface \ Area \ of \ Cuboid=2(370)\\Surface \ Area \ of \ Cuboid=740\: cm^2[/tex]

So, Surface Area of Cuboid C = 740 cm²

So, We get:

Surface Area of Cuboid A = 548 cm²

Surface Area of Cuboid B = 440 cm²

Surface Area of Cuboid C = 740 cm²

The company wants to choose the design having smallest surface area.

So, smallest surface area is of Cuboid B i.e 440 cm²

So, The company will choose cuboid B

Step-by-step explanation:

Answer:

y = 2x + 0 or y = 2x

Step-by-step explanation:

use slope-intercept form [tex]\frac{y2 - y1}{x2 - x1}[/tex]

12 - 10 = 2

6 - 5 = 1

m value = 2/1 = 2

y=2x+b

to find b plug one of the points in for x and y

Example: 10 = 2(5) + b

solve equation

10 = 10 + b

subtract 10 from both sides

0 = b

Equation of line equals y=2x+0 or simply just y=2x

Answer:

1. The ratio in the table above is a 2.5 : 1 ratio.

2. The second row represents that if you use 15 cups of flour you need 6 tablespoons of flour. (I’m not 100% sure this one is right)

3. 10 cups of flour and 4 tablespoons vanilla

Step-by-step explanation:

3. If you divide your number of flour by 2.5 you get the amount of vanilla you must use

Answer:

b+2=b-2

Step-by-step explanation:

The first step to solving this equation is subtract b from both sides. After you do that, you get 2=-2. 2 does not ever equal -2 and that statement is false. Therefore that equation has no solution.

Answer:

The square root is 5 units.

Step-by-step explanation:

It is given that:

Square area is 25 units square.

We have to find the square root.

Square root = [tex]\sqrt{25}[/tex]

Square root = [tex]\sqrt{5*5}[/tex]

Square root = 5 units

Therefore,

The square root is 5 units.

Answer:

Angle 1

Step-by-step explanation:

The angle supplementary to 5 is 1 because two angles are supplementary when they add up to 180 degrees.

So therefore, on the other/opposite side of angle 5 is angle 1.

The supplementary angle to ∠5 is D. ∠6 as the sum of this two angles is 180°.

We know when a transversal intersects two parallel lines at two distinct points,

Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.

We know two angles are supplementary if the sum of their measure is 180°.

Now, From the given diagram we can conclude that a straight line is forming with ∠5 and ∠6, So the sum of these angles must be 180° hence supplementary.

Therefore, The angle supplementary to ∠5 is ∠6.

Answer:

3/2

Step-by-step explanation:

The ratio of males to females in a cycling club is 5:3.

1/3 of the males are under 18

2/9 of the females are under 18

The fraction of the club members that are under 18 is calculated as:

Male: Female = Male/Female

We are told in the above question:

1/3 of the males are under 18

2/9 of the females are under 18

Hence:

1/3 / 2/9

= 1/3 ÷ 2/9

= 1/3 × 9/2

= 3/2

The fraction of the club members that are under 18 is 3/2

Answer:

y-int= -4

y-int= 5

y intercept is the point where x = 0.

[tex]y = (0+4)(0-5) = 4\cdot(-5) = -20[/tex]

Answer:

x = -1

Step-by-step explanation:

1. Simplifying

6x + 4 = 4x + 2

2. Reorder the terms

4 + 6x = 4x + 2 to 4 + 6x = 2 + 4x

3. Solving

4 + 6x = 2 + 4x

4. Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right. Then add '-4x' to each side of the equation.

4 + 6x + -4x = 2 + 4x + -4x

5. Combine like terms: 6x + -4x = 2x

4 + 2x = 2 + 4x + -4x

6. Combine like terms: 4x + -4x = 0

4 + 2x = 2 + 0

4 + 2x = 2

7. Add '-4' to each side of the equation.

4 + -4 + 2x = 2 + -4

8. Combine like terms: 4 + -4 = 0

0 + 2x = 2 + -4

2x = 2 + -4

9. Combine like terms: 2 + -4 = -2

2x = -2

10. Divide each side by '2'.

x = -1

11. Simplifying

x = -1

Answer:

The value of -18x + 30y is -27

Step-by-step explanation:

Algebraic Expressions

It's given that:

6x - 10y = 9

We are required to find the value of

-18x + 30y

The easiest way to solve the problem is to visualize that:

-18x = -3(6x)

30y = -3(-10y)

This means that the second expression is equal to the first expression multiplied by -3, thus:

-18x + 30y = -3(6x - 10y) = -3*9 = -27

The value of -18x + 30y is -27

3x(x)+3x(8)  +  7(x)+7(8)

3x^2+24x+7x+56=

56+31x+3x²

Answer:

3x^2+31x+56

Step-by-step explanation:

First, we need to multiply using the FOIL (first, outer, inner, last) method.

Let's multiply the first terms together:

3x(x)=3x^2

Now we multiply the outer terms:

3x(8)=24x

Next we multiply the inner terms:

7(x)=7x

Finally, we need to multiply the last terms:

7(8)=56

Now we have this:

3x^2+7x+24x+56

Combine like terms:

3x^2+31x+56
