Answer 1

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

Pedro bought 4 tickets to go to "Off the Wall". He paid $35.96 without taxes. Write and solve an equation to find the average price of tickets.

Answers

Answer: $8.99

Step-by-step explanation:

From the question, we are informed that Pedro bought 4 tickets to go to "Off the Wall" and that he paid $35.96 without taxes.

To find the average price of tickets, we have to divide the amount paid by the tickets bought. This will be:

= $35.96 / 4

= $8.99

What is the slope of the line shown below?

Answers

Answer: C. 5/6

Steps:

Use the formula x1-x2/y1-y2 to find the slope

(5,11), (-5,-1)

-5-5/-1-11
= -10/-12
=5/6

Answer:

[tex]m= \frac{6}{5}[/tex]

Step-by-step explanation:

Slope can be calculated using following formula

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Here

[tex](x_1, y_1) = (-5, -1) \ \ and \ \ (x_2, y_2) = (5, 11)[/tex]

Slope m is given as

[tex]m=\frac{11-(-1)}{5-(-5)}[/tex]

[tex]m=\frac{12}{10}\\m=\frac{6}{5}[/tex]

Answers

Answer: 210 tickets

Explanation:

1. Multiply the number of tickets he sold on Monday (21) by 3. (21x3=63)

2. Multiply the number of tickets he sold on Tuesday (63) by 2. (63x2=126)

3. Add all of those together to get the answer. (21+63+126=210)

Monday = 21
Tuesday = 21(3) = 63
Wednesday = 63(2) = 126

21 + 63 + 126 = 210 tickets

It’s urgent help me I have maths today plz help me!!

Answers

Answer:

Step-by-step explanation:

Vertices of the given triangle ABC are A(-1, 4), B(-1, 1) and C(-3, 1)

Equation of the mirror line → y = x

Rule to reflect these vertices over the mirror line y = x,

(x, y) → (y, x)

Therefore, image points of the vertices will be,

A(-1, 4) → A'(4, -1)

B(-1, 1) → B'(1, -1)

C(-3, 1) → C'(1, -3)

Now we can plot these image points to get the image triangle A'B'C'.

What is the surface area if this sphere?

Answers

Answer:

The surface area of the sphere is approximately equal to 379.9 square centimetres.

Step-by-step explanation:

The surface are a of a sphere with respect to radius is 4πr². We're given the diameter, of 11 cm, so we know that the radius is 5.5 cm.

With that we can find the surface area:

[tex]a = 4\pi r^2\\a = 4\pi (5.5cm)^2\\a = 4\pi \times 30.25cm^2\\a = \pi \times 121cm^2\\a \approx 3.14 \times 121cm^2\\a \approx 379.9cm^2[/tex]

two boys decided to share their profits from a car wash job at a ratio of 2:3 how much will each boy receieve if their total profit is 35

Answers

Answer: Profit for first boy = $14

Profit for second boy = $21

Step-by-step explanation:

Given : Ratio of profits = 2:3

Let profit for one boy = 2x and for another boy = 3x

Since combined profit = $35

Then, 2x+3x= 35

⇒ 5x= 35

⇒ x= 7 [divide both sides by 5]

Profit for first boy = 2 (7)= $14

Profit for second boy = 3 (7)= $21

I need to solve for x

Answers

Answer:

x=2+√14

Step-by-step explanation:

log(x)+log(x−4)=1

log(x to the second power−4x)=1

Step 1: Solve Logarithm.

log(x2−4x)=1

10log(x2−4x)=101(Take exponent of both sides)

x2−4x=101

x2−4x=10

x2−4x−10=10−10(Subtract 10 from both sides)

x2−4x−10=0

For this equation: a=1, b=-4, c=-10

1x2+−4x+−10=0

−b±√b2−4ac

(Use quadratic formula with a=1, b=-4, c=-10)
