Answer:

Surface Area

Step-by-step explanation:

Its's basically the total area of all faces in the three-dimensional figure.

Final answer:

The total area of all the faces of a three-dimensional figure is known as the surface area. It can be calculated differently based on the shape, like multiplying one face's area by six for a cube or summing up the areas of each face for a more complex shape.

Explanation:

The total area of all the faces of a three-dimensional figure is called the surface area. There are various methods to calculate the surface area depending on the shape of the three-dimensional object. For example, a cube has six faces, and the surface area can be found by calculating the area of one face and then multiplying by six. For more complex shapes, one might need to calculate the area of each face separately and sum them up.

For instance, taking a cube, if each face has an area of 4 square inches, then the total surface area of the cube would be 4 square inches multiplied by 6 faces, resulting in 24 square inches. If we then divide this cube into smaller cubes, the surface area-to-volume ratio of these smaller cubes would increase. When dealing with areas or volumes of objects with complex shapes, often, they're idealized to reflect simpler shapes like a cube or a sphere.

Assuming that the diameter of the circle is the square's side, then we have

Area of square: S1=10×10=100in²

Radius of circle: r=10/2=5in

Area of circle: S2=pi×r²=3.14×5²=78.54in²

Remaining area: S1-S2=100-78.54=21.46in².

Rounding to the nearest tenth: 21.5in².

Answer: 21.5in²

The area of the square not covered by the circle is calculated by first determining the areas of the square and the circle, and then subtracting the latter from the former. The area of the square is 100 square inches and the area of the circle is approximately 78.5 square inches. Subtracting these gives approximately 21.5 square inches.

First, let's find the area of the square. Since all sides are equal in a square, the area can be found using the formula side ⨉ side. In our case, the sides of the square are 10 inches, so the area is 10 inches ⨉ 10 inches = 100 square inches.

Next, we'll need to find the area of the circle. The radius of the circle is equal to half the length of a side of the square, or 5 inches. Use the formula for area of a circle, which is πr². So the area of the circle is π(5 inches)² = 25π square inches ≈ 78.5 square inches.

To find the area of the square not covered by the circle, simply subtract the area of the circle from the area of the square. 100 square inches - 78.5 square inches = 21.5 square inches, thus this is the area of the square not covered by the circle.

Step-by-step explanation:

sorry if its wrong it was correct for me

Answer:

B length = 8 in.; width = 4 in

Step-by-step explanation:

Given

the length L = w + 4

Perimeter = 24 inches

Perimeter of a rectangle

= 2(L + W)

We now have two equations.

Equation 1: L = w + 4

Equation 2: P = 2(L + W)

Substitute L as w + 4 into equation 1. And 24 for p

Therefore

24 = 2(w + 4 + w)

24 = 2(2w + 4)

Distribute 2 into (2w + 4)

We have

24 = 2 x 2w + 2 x 4

24 = 4w + 8

Subtract 8 from both sides

24 - 8 = 4w + 8 - 8

16 = 4w

Divide both sides by 4

16/4 = 4w/4

4 = w

w = 4 inches

Now substitute 4 for w into either of the equations to get

L.

Using equation 1 , we have

L = w + 4

L = 4 + 4

L = 8 inches

Step-by-step explanation:

Answer: the numbers are 9 and 2

Step-by-step explanation:

Let the numbers be a and b

a + b = 11.........equation 1

ab = 18.......equation 2

Multiply equation 1 by a

a ^2 + ab = 11a.......equation 3

Substitute the value of ab from equation 2 into equation 3

a ^2 + 18 = 11a

a^2 - 11a + 18 = 0

(1, 4)

Step-by-step explanation:

To solve simultaneous equation, we can use either of these three methods. Substitution method, elimination method or graphical method. But for the purpose of this question, we would be using the elimination method.

-3x+2y=5 Equation 1

3x+y=7. Equation 2

Since in the two equations, x has the same coefficient, we can eliminate x by adding both equations together

-3x+3x=0

2y+y=3y

5+7=12

We now have 3y=12

Divide both sides by 3

y=12/3

y=4

Substitute y for 4 in equation 2.

3x+4=7

3x=7-4

3x=3

Divide both sides by 3

x=3/3

x=1

x=1 and y=4

Answer:

Scale did the architect use to create the scale of the sports stadium is 1 inch = 15 feet.

Step-by-step explanation:

Given : An architect build a scale model of a sports stadium that was 12 inches. The actual height of the building was 180 feet.

To find : Which scale did the architect use to create the scale of the sports stadium?

Solution :

An architect build a scale model of a sports stadium that was 12 inches.

The actual height of the building was 180 feet.

The scale is determined by number of feet used in 1 inch.

i.e. For 12 inches it is 180 feet

For 1 inch = [tex]\frac{180}{12}[/tex] feet

1 inch = 15 feet

Therefore, scale did the architect use to create the scale of the sports stadium is 1 inch = 15 feet.

Answer:

Step-by-step explanation:

Just use a calculator and type in the [tex]\sqrt{51}[/tex]

Answer:

13 and -14 satisfy this condition

Step-by-step explanation:

Let's represent that number as x

and the square of x is x^2

So,

x + x^2 = 182

Subtract 182 from both sides

x + x^2 - 182 = 182 - 182

x + x^2 - 182 = 0

rearrange the quadratic equation

x^2 + x -182 = 0

let's use the quadratic formula

[tex]\frac{-b+\sqrt{b^2-4ac} }{2a}[/tex]       or      [tex]\frac{-b-\sqrt{b^2-4ac} }{2a}[/tex]

a = 1, b = 1, c = -182

[tex]\frac{-1+\sqrt{1^2-4*1*(-182)} }{2*1}[/tex]       or     [tex]\frac{-1-\sqrt{1^2-4*1*(-182)} }{2*1}[/tex]

[tex]\frac{-1+\sqrt{1+728} }{2}[/tex]      or         [tex]\frac{-1-\sqrt{1+728} }{2}[/tex]

[tex]\frac{-1+\sqrt{729} }{2}[/tex]            or    [tex]\frac{-1-\sqrt{729} }{2}[/tex]

[tex]\frac{-1+{27} }{2}[/tex]     or    [tex]\frac{-1-{27} }{2}[/tex]

[tex]\frac{26}{2}[/tex]     or    [tex]\frac{-28}{2}[/tex]

13 or    - 14

Lets check

13 + 13^2 = 13 + 169

= 182

Also,

-14 + (-14^2) = -14 + 196

= 182

If the school bus travels at an average speed of 1.0 km/min, it will take 52 minutes to complete the 52 km trip back to the school.

It is given in the question that the school bus is traveling at an average speed = 1.0 km/min

The total distance the school bus will cover on the trip back to the school  is = 52 km

According to the formula of speed,

Speed = Distance/Time

So, Time = Distance/Speed

Substituting the given values of distance and speed, we get

Time = 52 km/1.0 km/min

         = 52 minutes

Therefore, the time being taken by the school bus to complete the 52 km trip back to the school (average speed = 1.0 km/min) = 52 minutes

Required margin of error  = 20

Step-by-step explanation:

Required margin of error = 20

so , option (2) is the correct answer.

Explanation:

Values are given as,

we will have to need confidence level to calculate margin of error so ,we assume 95% confidence level .



z = 1.96 (critical value of 95%)

sample size n = 25

standard deviation = 50

Using the formula

Margin of error E =  z∗(σ/ n )  

putting the values

1.96∗(50/ 25)  

= 19.6

=20

Required margin of error :  E = 20

Answer: Jo's margin of error is M = 20

Step-by-step explanation:

The margin of error can be calculated as:

M = z*σ/√n

where:

z depends on the confidence interval with we are working, let's use 95%, so z = 1.96

σ = standard deviation = 50

n = number of the sample.

So for Jo we have:

M = 1.96*50/√25 = 1.96*50/5 = 1.96*10 = 19.6

So if we round it to the nearest whole number, we should round up, and we get:

M = 20

Step-by-step explanation:

This is because the range is greater and the minimum and maximum are higher numbers.

The solution to the box plot is is the lengths of time that his mom reads are typically longer and have more variability than the lengths of time that his dad reads.

A box and whisker plot, often known as a box plot, shows a data set's five-number summary. The minimum, first quartile, median, third quartile, and maximum make up the five-number summary.

A box is drawn from the first quartile to the third quartile in a box plot. At the median, a vertical line passes through the box.

It is used when showing the distribution of data points across a selected measure and if the box in a box plot is stretched in one direction or the other, then the data is skewed in that direction.

Given data ,

Let the box plots be represented as A and B

Now , the box plot A represents the minutes Mom used to spend during reading

And , the box plot B represents the minutes Dad used to spend during reading

From the box plots , we can see that the range is greater in the box plot A and the minimum and maximum are higher value numbers when Mom is reading the bedtime stories
