Answer:5.3

Step-by-step explanation:

using the Pythagorean theorem 8²-6²=28    √28=5.3

5

Step-by-step explanation:

Pythagoras theorem states that

a²+b²=c²

therefore a²=b²-c²

a²=8²-6²

a=√8²-6²

=√64-36

=√28

=5.3 or approximately 5

Answer:

Step-by-step explanation:

We can observe:

According to  Hınge theorem if two sides of different triangles are equal and the angles between the two sides are different, then the larger angles has greater side opposite to it.

As TU is opposite to the larger angle, and SV is opposite to smaller angle, then TU > SV.

Correct angle choice is B.

The area of one triangle is 28 cm².​

From the question, we have

area = 1/2*base*height

=  1/2*8*7

=28 cm².

Multiplication:

In mathematics, multiplying the numbers is used to find the product of two or more numbers. We carry out one of the basic mathematical operations on a regular basis. The main application that is obvious is using multiplication tables. Mathematicians use the multiplication of two integers to express the repeated addition of one number to another. These numbers can be natural numbers, fractions, integers, whole numbers, etc. M is either added to itself 'n' times or subtracted from itself when m is multiplied by n.

The height of the tower is 9.24 feet. That is, the tower is 9.24 feet tall

From the question, we are to determine how tall the tower is

From the given information,

From a distance of 10 feet, the angle of elevation of the tower at a height 5 feet from the ground is 23 degrees.

Let x represent the length of the tower from a point 5 feet from the ground.

Thus,

The height of the tower will 5 + x feet

Now, we will determine x

Using SOH CAH TOA

tan 23° = x / 10

x = 10 × tan 23°

x = 4.24 feet

Height of the tower is 5 + x feet

Therefore,  

Height of the tower = 5 + 4.24 feet

= 9.24 feet

Hence,

The height is 9.24 feet

A. The expression in the simplest form that represents the amount (in dollars) it costs to adopt x dogs is 195x

B. The coefficient of the expression in part (a) represents D. The the total amount the animal shelter earns when x dogs are adopted

Expression simply refers to the mathematical statements which have at least two terms which are related by an operator and contain either numbers, variables, or both.

In this situation, to adopt a dog from an animal shelter, you must pay $80 for vaccinations, $65 to spay or neuter the dog, and $50 for a wellness exam by a veterinarian.

Therefore, the expression to adopt x dogs will be:

= 80(x) + 65(x) + 50(x)

= 80x + 65x + 50x

= 195x

This is the cost for x dogs.

[tex]\frac{7}{11}[/tex], [tex]\frac{7}{9}[/tex], [tex]\frac{7}{8}[/tex]

Hope this helps!

Step-by-step explanation:

One way to find this out is by just plain dividing the numbers, 7 ÷ 11 is 0.636363..., 7 ÷ 9 is 0.7777777..., and 7 ÷ 8 is 0.875. 7/11 is the smallest of all of them, then 7/9, and then 7/8.

When John read 7 and 1/2 pages in 2/5 of an hour, the rate in pages per hour that he read is 18.75 per pages.

It should be noted that rate is used to show the comparison between two things.

In this case, John read 7 and 1/2 pages in 2/5 of an hour.

The number of pages read per hour will be the division of the values given. This will be:

= 7 1/2 ÷ 2/5

= 7.5 / 0.4

= 18.75 pages

The pages is 18.75 pages.

The price of ticket will be $26 approximately in 2009 using the concept of the linear equation and slope.

Ax+By=C is the usual form for two-variable linear equations. A standard form linear equation is, for instance, 2x+3y=5. When an equation is given in this format, finding both intercepts is fairly simple (x and y). When attempting to solve systems of two linear equations, this form is also very helpful.

Here,

The line has 2 points,

(2001,18) and (2005,22)

m=(22-18)/(2005-2001)

m=1

y-y1=m(x-x1)

y-18=x-2001

x-y=1983

(2009,y) is on that line,

2009-y=1983

y=26

Using the idea of the linear equation and slope, the ticket price in 2009 will be approximately $26.

A swimming pool shaped like a rectangular prism has a volume of 124 cubic meters.

Rectangular prism is a three-dimensional shape that has 6 rectangle faces, 12 edges and 8 vertices.

Volume is defined as the amount of space that a three-dimensional shape occupies.

The volume of a rectangular prism can be calculated using the formula below.

V = l x w x h

where V = volume

l = length

w = width

h = height or depth

Plug in the values to the formula, multiply by the conversion factor, and solve for the volume.

V = l x w x h

V = (26 feet)(14 feet)(12 feet)(0.305 meter/foot)³

V = 124 cubic meters

The number of pieces the bakery will sell is 16 and a half. The total amount of money they will make is $82.5.

To get the number of pieces of pies that they have to sell, we need to first determine how many 1/4 pies are in 4 and 8 pieces of bread. Going by that, we can see that:

1/4x of 4 = 16.

Also, 1/4x of 1/8 = 1/2.

So, the total number of pies that they have to sell is 16 and a half.

Now if 1/4 of a pie costs $5, then 4 1/8 will be equal to 33/8 × 5 ÷ 1/4.

This is equal to 165/8 × 4 = $82.5

So, the total amount of money that the bakery will make will be $82.5.

Answer:

4x + y = 21

Step-by-step explanation:

1. distribute in the parenthesis first, so the right side of the equation is not -4x+24

Right now the total equation looks like y+3 = -4x+24

2. Now we add the 4x to both sides to cancel it out on the left side, so we're left with:

4x+y+3=24

3. After that we can subtract the 3 from both sides to leave us with:

4x+y=21

Answer: it is not 27%

Step-by-step explanation:

The way that one number in the second equation be changed so the system has only one solution is;  to divide each term by 2 to get the coefficient of y as 5.

There are different methods to solve simultaneous equations such as;

We are given the equations as;

3x + 5y = 4

16x + 10y = 4

Now, we want to perform an operation whereby we make the second equation be changed so the system has only one solution. This method is the elimination method.

The elimination method is the process that we use to eliminate one of the variables in the system of linear equations with the aid of the addition or subtraction methods as well as multiplication or division of coefficients of the variables.

Now, since we have 5y in the first equation, the first step to carry out on the second equation is to divide each term by 2 to get the coefficient of y as 5.

The Latin term "per centum," which signifies "by the hundredth," was the source of the English word "percentage." Segments with a denominator of 100 are considered percentages. In other terms, it is a relationship where the worth of the entire is always considered to be 100.

Total members = 850

Number of members registered for batting = 80%

Number of members registered for fielding = 56%

Members who participated in both,

80% of 850 + 56% of 850 - x = 850

In order to get the same outcomes as a form mirrored across the y-axis and turned counterclockwise, a shape can be reflected across the x-axis and then rotated 90 degrees in a clockwise manner around the origin. This suggests a similarity between these two transformative sequences.

What does mathematics mean by reflection?

A flip is the term used in geometry to describe a reflection. The mirror image of the form is a reflection. An image can reflect through a line known as the line of reflection. When all of the points in a figure are evenly spaced away from one another, the two figures are said to reflect each other.

(X, Y) > when a form is rotated 90 degrees counterclockwise (y, -x).

When the picture is reflected across the y-axis, (x, y) > (-x, y).

When those two transformations are used, it is the same as reflecting a shape across the line y = -x, where (x, y) > (-y, -x).

For instance: After being rotated 90 degrees clockwise and reflecting across the y-axis,

(2, 1) > (1, -2) > (-1, -2); and

(2, 1) > (-1, -2)

after being reflected across the y = -x line
