Answer:

No

Step-by-step explanation:

The tangent line must form a right angle with the radius

No, 4 5 6 isn't a right triangle

Answer:

Line m is not a tangent line to circle B.

Step-by-step explanation:

The tangent line to a circle is always perpendicular to the radius.

The line segment measuring 4 units is the radius of Circle B, therefore if line m is a tangent line to the circle, the angle between this segment and the segment measuring 5 units will be a right angle (90°).

We can use Pythagoras' Theorem to check if the triangle is a right triangle.

Pythagoras’ Theorem:  [tex]a^2+b^2=c^2[/tex]

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

Therefore, the legs are the line segments measuring 4 and 5, and the hypotenuse is the line segment measuring 6 units.

Substituting the values for the legs into the formula:

[tex]\implies 4^2+5^2=c^2[/tex]

[tex]\implies 16+25=c^2[/tex]

[tex]\implies 41=c^2[/tex]

[tex]\implies c=\sqrt{41}[/tex]

Therefore, as the hypotenuse of the triangle is not √41, the triangle is not a right triangle, and therefore line m is not a tangent line to circle B.

The solution  of the given  two positive consecutive even integers will be  a = 20 and b = 21

An integer is a number whose values are ranges from 0 to infinite positive and zero to infinite negative.

Given that :

2a-3b = -23

a and b are consecutive

Find:

a and b

Computation:

a = b - 1

So,

2a-3b = -23

2(b-1)-3b = -23

2b - 2 - 3b = -23

-b = -21

b = 21

So

a = b - 1

a = 21-1

a = 20

Hence the solution  of the given  two positive consecutive even integers will be  a = 20 and b = 21

Answer:

47 degrees

Step-by-step explanation:

Similar just means they may be different sizes but have the same angle measure. That means the angles will be identical in both triangles A and B.

All angles must add up to 180 degrees. We already have two angles, so we just need to find the last one. 90+43= 133.

180-133=47.

Answer: 5 hours

Step-by-step explanation:

[tex]speed=\frac{distance}{time}[/tex]

Andy speed = 7.5/3 = 2.5 mph

William speed = 15/4 = 3.75 mph

1. Write an equation that represents the question

let h = # of hours it takes William to catch up with andy

   2.5h + 6.25 = 3.75h

2. subtract 2.5h from both sides

   6.25 = 1.25h

3. Divide 1.25 from both sides

   [tex]\frac{1.25h}{1.25} =\frac{6.25}{1.25}[/tex]

   h = 5

Therefore, we know it will take 5 hours for William to catch up with andy.

An equation is an expression that shows the relationship between two or more numbers and variables.

Volume of pyramid = (1/3) * area of base * height

Hence:

3240 = (1/3) * (20 * 18) * x

Step-by-step explanation:

if that is a problem for the end of the school year, what problems did you solve during the year ?

this question needs one of the basic principles of angles :

the sum of all angles around one point on one side of a line is always 180°, because that line can be seen as the diameter of a circle, and the point is the center of that circle. so, all angles in one side of the line are representing a half-circle.

this special point here is clearly T.

and 85 + x = 180

x = 180 - 85 = 95°

Answer:

Squares and triangles are both polygons and right triangles and squares both have at least one right angle. They are different because squares have 4 sides and triangles have 3. Also, triangle have a total of 180 degrees while squares have a total of 360 degrees.

The first equation will be x²-12x+27=(x-9)(x-3). The second equation will be x²-9x+20=(x-5)(x-4).

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

1. For the first equation to be complete, we need to expand the factors, therefore, we can write,

(x-9)(x-3)

= x² - 9x - 3x + 27

=x²-12x+27

Hence, the first equation will be x²-12x+27=(x-9)(x-3).

2. For the second equation to be complete, we need to factorise the left side of the equation, therefore, we can write,

x²-9x+2

= x²-5x-4x+20

= x(x-5)-4(x-5)

=(x-5)(x-4)

Hence, the second equation will be x²-9x+20=(x-5)(x-4).

Step-by-step explanation:

So as we know, 30/x = 100/80

100/80 = 1.25

Now we have 30/x = 1.25

Multiply both sides of the equation by x - (30/x)x = (1.25)x

Now we have 30 = 1.25x

Divide both sides by 1.25 - 30/1.25 = 1.25x/1.25

Answer:

The circumference of a circle with a radius of 7 millimeters is 44.0 (rounded to the nearest tenth).

Step-by-step explanation:

The circumference of a circle is the distance around the outside of the circle. The circumference along with the diameter and radius are the 3 major aspects of a circle.

The circumference of a circle is found using this formula:

For this problem, the radius has been given, so to solve, let's use the formula: [tex]c=2\pi *r[/tex].

It has been given that the radius is equal to 7 and the unit of measure is millimeters.

So to start, let's plug the radius in the formula.

It should look like this: [tex]C=2\pi *7[/tex]

After plugging the radius into the formula, we now have to multiply [tex]2\pi[/tex] by [tex]7[/tex]; resulting in: ≈ [tex]43.9823[/tex] (estimate)

Now rounding to the nearest tenth:

≈ [tex]44.0[/tex]

Well, you need to know the aton mic weight of Platinum (Pt) and the number of atoms per mole. The answer to the former is 195.084 g/mole and the latter is 6.023 * 10^23 atoms/mole. Then, multiply everything as shown below:

Number of atoms = (1 g) * (1/195.084 g/mole) * 6.023 * 10^23 atoms/mole

Number of atoms = 3.087 * 10^21 atoms

Note, I’ve included units on everything and you can see that they all cancel except for atoms. Dragging the units along can be a pain but it is a great way to check that they way the numbers are being combined is

Inequalities help us to compare two unequal expressions. The number of seats in each row on the floor must be less than 18.

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.

Given the balcony has 400 seats, and the floor has 50 rows with each row having x number of seats. Therefore, the number of seats on the floor will be,

Number of seats on floor = 50 × x = 50x

Since the total number of seats in the auditorium should be less than 1300, therefore, the inequality can be written as,

Number of seats in balcony + Number of seats on floor < 1300

400 + 50x < 1300

50x < 1300-400

50x < 900

x < 18

Hence, the number of seats in each row on the floor must be less than 18.
