Answer:

4.24

Step-by-step explanation:

you should use the pythagorean theorem to solve this!

a^2 + b ^2 = c^2

3^2 + 3^2 = c^2 (i got 3 because it goes down three, and over three)

9 + 9 = c^2

18 = c^2

the square root of 18 is 4.24

therefore, the distance between C and D is 4.24.

Answer:

x=8

Step-by-step explanation:

If you subtract 3 from both sides then subtract -x/2 from both sides your equation should be simplified down to

-x/2 = -4. if you multiply the 2 on both sides the equation is -x=-8. but now you have to divide by negative 1 on both sides and you get x=8

Answer:

It is C. If a2 + b2 =c2, then the triangle is a right triangle.

Step-by-step explanation:

If a triangle has side lengths a, b, and c, where c is the longest side, then the statement "If a2 + b2 = c2, then the triangle is a right triangle", the correct option is C.

The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.

|AC|^2 = |AB|^2 + |BC|^2    

We are given that;

Sides of triangle are a, b and c

Now,

This statement is known as the Pythagorean Theorem, which states that in a right triangle, the sum of the squares of the lengths of the legs (a and b) is equal to the square of the length of the hypotenuse (c).

Conversely, if a triangle satisfies the Pythagorean Theorem, then it is a right triangle.

Therefore, by Pythagoras theorem the answer will be a2 + b2 = c2, then the triangle is a right triangle.

Answer:

Yes, Line AB is tangent to the circle.

Step-by-step explanation:

Answer:

volume of a cone = 2.82πinches³( nearest hundredth)

Step-by-step explanation:

given that the diameter of a cone = 2 3/8

diameter = radius x 2

radius = diameter /2

radius = 19/8/2 = 1.1875

height of the cone = 6inches

volume of the cone = ?

recall that the formulae for calculating the volume of a cone = πr² h/3

volume of a cone = πr² h/3

volume of a cone = π (1.1875)² x 6/3

volume of a cone = π1.410 x 2

volume of a cone =  2.8203πinches³

volume of a cone = 2.82πinches³( nearest hundredth)

I graphed the equation on the graph below to find the x values.

Answer:

1

Step-by-step explanation:

We can find the slope by using any two points and the following formula

m = (y2-y1)/(x2-x1)

   = (5-3)/(2-0)

    = 2/2

    =1

The equation is [tex]2\frac{1}{8} - \frac{1}{2}[/tex] .

1/2 is equivalent to 4/8, and 2 1/8 is equal to 17/8. (two full sets of 8 + 1 = 8 + 8 + 1, or 17)

The new equation is [tex]\frac{17}{8} -\frac{4}{8}[/tex] . Subtract the numerators.

17 - 4 = 13 or 13/8

The improper fraction [tex]\frac{13}{8}[/tex] simplifies to [tex]1\frac{5}{8}[/tex] .

[tex]1\frac{5}{8}[/tex]

Step-by-step explanation:

There are "6" people in total.

They can come at any place and at any time. All of them have equal chances of arriving at any place.

Similarly,

Everyone has the same chances of coming first.

Hence, the probability of Xerxes coming first is 1 out of 6 people

Hence,

Probability (Xerxes coming first) = 1/6

The answer is [tex]\frac{1}{6}[/tex]

Answer:

(h+8)^2 + ( y +1)^2 = 9

Step-by-step explanation:

The equation of a circle can be written as

(x-h) ^2 +(y-k) ^2 = r^2

where (h,k) is the center and r is the radius

(h- -8)^2 + ( y - -1)^2 = 3^2

(h+8)^2 + ( y +1)^2 = 3^2

(h+8)^2 + ( y +1)^2 = 9

Answer:

(x + 8)² + (y + 1)² = 9

Step-by-step explanation:

Equation of a circle

(x - h)² + (y - k)² = r²

(x - -8)² + (y - -1)² = 3²

(x + 8)² + (y + 1)² = 9

Step-by-step explanation:

=====================================================

Explanation:

Each circle has a radius of 'a'. So r = a.

The area of each circle is pi*r^2 = pi*a^2

The area of each square with side length b is b^2

The two stacks have the same volume only when the circle area is equal to the square area, so whenever pi*a^2 = b^2 is true.

Solving for b leads to b = sqrt(pi*a^2) = sqrt(pi)*a

The stacks must also be the same height for the volumes to be the same, so m = n as well.

Answer:

Step-by-step explanation:

hello :

here is an solution :

The probability that a student chosen at random plays football or cricket or both is approximately 0.8667, or 86.67%, after considering the number of students playing each sport and accounting for those who play both.

To calculate the probability that a student chosen at random plays football or cricket or both, we can use the concept of probability along with a Venn diagram to organize our information.

First, we need to calculate the total number of students that play at least one of the sports. We know that 8 students play both football and cricket, 14 students play football, and 20 students play cricket. However, the 8 students that play both sports are included in the totals for both football and cricket. Therefore, to find the number of students who play at least one sport, we need to subtract the students counted twice because they play both sports:

Total playing football or cricket or both = (Number playing football) + (Number playing cricket) - (Number playing both)
= 14 + 20 - 8
= 26 students

We also know there are 4 students who do not play football or cricket. To find the total number of students, we add the number of students who play either sport to those who play neither:

Total number of students = 26 (playing sports) + 4 (not playing any sports)
= 30 students

The probability that a student chosen at random plays football or cricket or both is calculated by dividing the number of students who play either sport by the total number of students:

P(playing football or cricket or both) = Number of students playing sports / Total number of students
= 26 / 30
= 0.8667 (rounded to four decimal places)

The probability is approximately 0.8667, or 86.67%.

2x=500

Step-by-step explanation:

Let x be the number of days.

Since there is a pattern, that 1 person is infected and infects two. Then two infects 4.

So it will be 2x. Since everyday it goes up.

Then, since there are 500 students in the school and the question asks for how many days, it will equal 500.

Answer:

Explanation:

The figure attached shows sketches the situation described.

You have two right triangles.

For the right triangle with the plane on the position A, you can write:

         ⇒ H = (800 + x) tan(20º)

For the right triangle with the plane on the position B, you can write:

        ⇒ H = x tan(21.4º)

To solve, equal both equations:

Substitute in the equation H = x tan(21.4º)

The sequence of transformations will verify that △EFG and △E'F'G' are congruent is; C) △EFG is moved onto △E'F'G' after rotating 270 degrees counterclockwise around the origin, and then reflecting across the x-axis

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs), etc.

For triangle △EFG and △E'F'G'  to be congruent, we must first rotate 180° counterclockwise around the origin and then move EFG onto E'F'G'H'.

This proof of congruency is reflected across the y-axis.

Bottom left graph

Step-by-step explanation:

Since the y-coordinates are the same, but the x-coordinates are opposites, it is a reflection across the y axis.

Therefore, the bottom left graph is correct.

Answer: The Bottom Left Graph

Step-by-step explanation:

The Y coordinates are the same number, therefore, when you find the coordinates of the points, the y must be equal, making them the same height on a graph. The X coordinates on the graph must be opposites, therefore, the two dots have to be equidistant from the Y axis. The only graph that has two dots at the same height and is equidistant from the Y axis is the graph at the bottom Left Corner.
