Answer

Answers

Answer 1

He would need 54 ft² material to cover the one rectangular side of the tent with the rip and 213 ft² to recover the whole tent including the bottom. The volume of the tent is 189 ft³.

Part A

He would need 54 ft² material to cover the one rectangular side of the tent with the rip. As we have to find the area of a rectangular side of a rectangle we will use the formula Area= Length × Width

∴ Area of a Rectangle = length of the rectangle × width of the rectangle

A = 9 × 6

A = 54 ft²

Part B

David's dad would need 213 ft² material to recover the whole tent including the bottom. We know that the 2 sides of the tent are 54 ft² each. So, the total is 54 × 2 = 108 ft².

We will now find the area at the bottom of the tent

A = 7 × 9

A= 63 ft²

We will now find the area of the triangular sides

Triangle Area = 1÷2 × b×h

A = 1÷2 × 7 × 6

A =  1÷2 × 42

A = 21  ft²

As there are 2 triangular sides so we have to multiply it by 2

∴ 21 × 2 = 42 ft²

Add all the sides together 108  63 + 42 = 213 ft²

Part C

The volume of the tent is 189 ft³. It can be found by applying the formula V= b×h

Triangle area = 1÷2 × bh

A = 1÷2 ×7 × 6

A=  1÷2 × 42

A= 21

With a=21 as B and h= 9ft and applying the formula v=Bh

We have,

v = 21 × 9

v = 189 ft³

What is reflection ?

In Geometry, a reflection is known as a flip. A reflection is a mirror image of the shape. An image will reflect through a line, known as the line of reflection.

Given,

Graph of a quadrilateral ABCD

Tangent

The tangent of an angle is the ratio of the opposite side to the adjacent side.

How to find the volume of a pyramid?

The above diagram is a square base pyramid. The volume of the square base pyramid can be represented as follows:

volume of the pyramid = 1 / 3 BH

where

B = base areaH = height of the pyramid

Therefore,

base area = l²

where

l = side length

Hence,

base area = 5²

base area = 25 cm²

Therefore, let's find the volume of the pyramid.

Hence,

volume of the pyramid =  1 / 3 × 25 × 8

volume of the pyramid =  200 / 3

volume of the pyramid = 66.6666666667

A pyramid has a square base with sides of length 10 units. Each segment that connects the apex to a
midpoint of a side of the base has a length of 13 units. What is the height of the pyramid? What is the volume of the pyramid, units cubed?

Answers

The volume of the pyramid is 400 cubic units.

What is a pyramid?

A pyramid is a structure where outer surfaces are triangular and converge to a point at the top.

The volume of a pyramid with a square base is given as:

Volume = 1/3 x base area x height

We have,

Let's call the height of the pyramid "h".

We can use the Pythagorean theorem to find the slant height of the pyramid, which is the length of one of the edges from the apex to a corner of the base.

To do this, we can consider one of the right triangles formed by the apex, the midpoint of a side, and a corner of the base.

The hypotenuse of this right triangle is the segment connecting the apex to the midpoint of a side, which has a length of 13 units.

One leg of the right triangle is half of one side of the square base, which is 5 units.

The other leg of the right triangle is the height of the pyramid, which we want to find. So, we can write:

h² + 5² = 13²

Simplifying and solving for h, we get:

h²= 13² - 5²

h² = 169 - 25

h² = 144

h = 12

So, the height of the pyramid is 12 units.

To find the volume of the pyramid, we can use the formula:

Volume = (1/3) x Base Area x Height

The base of the pyramid is a square with sides of length 10 units, so its area is:

Base Area = 10² = 100 square units

Plugging in the values we know, we get:

Volume = (1/3) x 100 x 12

Volume = 400 cubic units

Therefore,

The volume of the pyramid is 400 cubic units.

Copy the diagram and write in the size of all the other angles.
Work out the unknown angles a, b and c
(It’s question 5)

Answers

In the diagram, one line is transversal of two parallel lines, so the value of a is 113°, value of b is 67° and value of c is 67°.

The parallel lines are what?

On a plane, lines that are parallel to one another never cross or come together. They are always parallel and equally spaced apart from one another. Parallel lines are lines that do not intersect. Lines are referred to as parallel if they never intersect and do not have a common intersection.

One line crosses two parallel lines in the diagram.

Angle an is the 113°'s vertically opposite angle.

Therefore, the angle's value is 113°.

Here, a and b have the same side interior angles since a line is transversal to two parallel lines.

So, a + b = 180°

⇒ 113° + b = 180°

⇒ b = 180° - 113°

⇒ b = 67°

And c is vertically opposite angle of b

So, the value of angle c = 67°

How to find the number that makes the ratio equivalent to 2:6?

Equivalent ratios are ratios that have the same value, but may have different numerator and denominator values. They are related to each other by multiplication or division of both the numerator and denominator by the same non-zero value.

For example, the ratios 2/4 and 1/2 are equivalent ratios because both represent the same fraction (1/2) and therefore have the same value.

In this case we have:

2:6 = 6: x

2/6 = 6/x

2 * x = 6 * 6

2x = 36

x = 36/2

x = 18

Answers

The four integers are 5, 5, 12 and 14.

What is Mean, Mode and Median?

A data set's mean (average) is calculated by summing all of the numbers in the set, then dividing by the total number of values in the set.

When a data collection is ranked from least to greatest, the median is the midpoint. The number that appears most frequently in a data set is called the mode.

Given:

Mean= 9

Median = 8.5

Mode = 5

Range = 9.

let the numbers arranged in ascending order are a,b,c,d

Median: b+ c /2 = 8.5

b+ c = 17 (number in the middle)

Mode: a = 5, b= 5 {because mode is the most repeating data}

Range: d- a = 9 (last one minus first one)

d= 9 + 5

d= 14

Now, b+c = 17

c= 17-5

c= 12

In mathematics, a group is a set that contains an operation that allows any two members to be connected to form a third element in such a way that the operation is associative, an identity element will be determined, and every element has its inverse. These three requirements, which are group axioms, are valid for number systems as well as numerous other mathematical structures. For instance, the integer set and addition operation are two examples of groups. Consequently, a group is a mix of a set and a binary operation, to put it simply.

a jazz concert brought in $157,437 on the sale of 8,856 tickets. if the tickets are sold for $10 and $20 dollars, how many of the $10 dollar ticket were sold?

Answers

1968 of the $10 dollar ticket were sold by jazz & 6873  of the $20 dollar ticket were sold by jazz.

Jazz total amount received = $157,437

Total tickets sold = 8,856

Let the $10 tickets sold = x

The $20  tickets sold = 8,856 - x

Here the solution below :

$10(x) + 8,856 - x($20) = $157,437

$10x + $177120 - $20x = $157,437

-$10x = $157,437 - $177120

-$10x = - $19683

x = 1968.3

1968 of the $10 dollar ticket were sold by jazz & 6873  of the $20 dollar ticket were sold by jazz.

Given that Ernest took a total of 12 quizzes over the course of 4 weeks. The number of weeks required to take 30quizzes will be calculated as;-

12 quiz = 4 weeks

1 quiz = 4 / 12 weeks

30 quiz = ( 4 x 30 ) / 12 week

30 quiz = 10 week

The number line that shows the solution set of the inequality is B

How to solve the inequality

In math, an inequality is a statement that describes a relationship between two values or expressions that are not equal. An inequality is written using mathematical symbols such as "<" (less than), ">" (greater than), "<=" (less than or equal to), ">=" (greater than or equal to), or "≠" (not equal to).

-1/2x ≥ 4

we are to get the value of x

-x ≥ 4 ÷ 1/2

- x ≥ 4 x 2

-x ≥ 8

x ≤ -8

The provided inequality is represented by an arrow with a solid point at x = -8 and an arrow pointing in the direction of negative values.

What is Proportion?

In general, the term "proportion" refers to a part, share, or amount that is compared to a total.

According to the concept of proportion, two ratios are in proportion when they are equal.

A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.

Given:

The directions on a sewing pattern say to cut an extra 15% of fabric to account for an error.

and Chloe needs a 0.75 yard of fabric to make a skirt, so she cuts 0.1125 yard.

The amount of Fabric needed

0.75 x 1.15 = X

0.8625 = X

and, Chloe cut the fabric

= 0.8625 - 0.1125

= 0.75

Thus, the amount of fabric that Chloe cut is correct.
