Note: Its equilateral not equitorial triangle .

Given:

The statement is "An equilateral triangle has 3 medians".

To find:

Whether the given statement is true or false.

Solution:

Median of a triangle connected the vertex and midpoint of opposite side of the triangle.

We know that that every triangle has three medians.

In case of equilateral triangle, all sides and angles are equal and median is the height of the triangle.

So, an equilateral triangle has 3 medians.

Therefore, the given statement is true.

Answer

$150

Step-by-step explanation:

Since there are 12 months in year, you multiply 25 times 24 to get 600. 75% of 600 is 450, so then you do 600-450. The answer to that is 150.

Answer:

We conclude that the equation of this line in the slope-intercept form will be:

Step-by-step explanation:

We know that the slope-intercept form of the line equation is

[tex]y=mx+b[/tex]

where m is the slope and b is the y-intercept.

Given the equation

[tex]3z +y=2[/tex]

Writing the equation in the slope-intercept form of the line equation by simplifying it

subtracting 3z from both sides

[tex]3z+y-3z = -3z+2[/tex]

[tex]y = -3z+2[/tex]

Therefore, we conclude that the equation of this line in the slope-intercept form will be:

Answer:

The first term is 3 and the common difference is 2

Step-by-step explanation:

The formula of the sum of the nth term of the arithmetic sequence is

[tex]S_{n}=\frac{n}{2}[2a+(n-1)d][/tex], where

∵ The sum of the first five terms of an arithmetic sequence is 35

∴ [tex]S_{5}[/tex] = 35

→ Substitute The values of n and S in the rule above

∵ 35 = [tex]\frac{5}{2}[2a+(5-1)d][/tex]

∴ 35 = [tex]\frac{5}{2}[2a+4d][/tex]

→ Simplify the right side

∴ 35 = 5a + 10d

→ Switch the two sides

∴ 5a + 10d = 35 ⇒ (1)

∵ The sum of the next five terms is 85

→ To find the sum of the first 10 terms add 85 to [tex]S_{5}[/tex]

∴ [tex]S_{10}[/tex] = 35 + 85 = 120

→ Substitute The values of n and S in the rule above

∵ 120 = [tex]\frac{10}{2}[2a+(10-1)d][/tex]

∴ 120 = 5[2a + 9d]

→ Simplify the right side

∴ 120 = 10a + 45d

→ Switch the two sides

∴ 10a + 45d = 120 ⇒ (2)

Now we have a system of equations to solve it and find a and d

→ Multiply equation (1) by -2

∵ -2(5a) + -2(10d) = -2(35)

∴ -10a + -20d = -70 ⇒ (3)

→ Add equations (2) and (3)

∵ (10a + -10a) + (45d + -20d) = (120 + -70)

∴ 25d = 50

→ Divide both sides by 25 to find d

∴ d = 2

→ To find a substitute d in equation (1) by 2

∵ 5a + 10(2) = 35

∴ 5a + 20 = 35

→ Subtract 20 from both sides

∵ 5a + 20 - 20 = 35 - 20

∴ 5a = 15

→ Divide both sides by 5

∴ a = 3

∴ The first term is 3 and the common difference is 2

Answer:The first picture, second picture,fourth picture represents proportional relationship.

Further explanation:

Explanation:

The points in the first picture are  and

The slopes between the points can be obtained as follows,

The slopes between the points are equal. Therefore, in the first picture x and y are in a proportional relationship.

The points in the second picture are  and

The slopes between the points can be obtained as follows,

The slopes between the points are equal. Therefore, in the second picture x and y are in a proportional relationship.

The points in the third picture are  and

The slopes between the points can be obtained as follows,

The slope is negative. Therefore, in the third picture x and y are not in a proportional relationship.

The points in the fourth picture are  and

The slopes between the points can be obtained as follows,

The slopes between the points are equal. Therefore, in the fourth picture x and y are in a proportional relationship.

The first picture, second picture,fourth picture represents proportional relationship.

Answer: The area is 4x^2-2x-6

Step-by-step explanation: The area of a rectangle is length*width. So multiply both these terms. Remember the method foil, that would apply here. (4x-6)(x+1), you end up with 4x^2+4x-6x-6. Then combine like terms, to get 4x^2-2x-6.

Step-by-step explanation:

Right Triangles

A right triangle is a special triangle that has an interior angle of 90°.

In right triangles, Pythagora's Theorem is satisfied:

[tex]c^2=a^2+b^2[/tex]

Where c is the hypotenuse (longest side) of the triangle, and a and b are the legs or the smaller sides.

The slide can be thought of as a right triangle whose hypotenuse is the slide itself and the legs are the height of the ladder and distance between the foot of the ladder and the end of the slide.

So we have:

[tex]c^2=22^2+10^2[/tex]

[tex]c^2=484+100=584[/tex]

[tex]c=\sqrt{584}[/tex]

c = 24.17 feet

Answer:

y = -f(x - 5)

Step-by-step explanation:

the function of the dotted graph is f(x) shifted (or translated) 5 units to the right and then reflected across the x-axis.

shifting it to the right is happening by reducing every x value by 5 (so that we get for x the functional value of x-5).

and reflecting it across the x-axis simply means to flip the sign. everything that was originally above the x-axis is now with the same distance below the x-axis (and vice versa).

therefore, the new

y = -f(x - 5)

12 - e < -2

- e < -2 - 12       Move 12 to subtract.

- e < - 14

e > 14     When the coefficient is in negative. Moving the negative as changing the sign of Inequality to opposite.

Therefore, the answer is e > 14

Answer:

4x6=24, 7x3=21 6x3=18 for C and 5x3=15 for D

Step-by-step explanation:

Math has patterns!

Given:

The ratio of the amount of money Kate has to that of Nora is 3 : 5.

After Nora gives $150 to Kate, the ratio of the amount of money Kate has to that of Nora becomes 7 : 9.

To find:

The sum of money Kate had initially.

Solution:

Let the initial amount of money Kate and Nora have are 3x and 5x respectively.

After Nora gives $150 to Kate, the ratio of the amount of money Kate has to that of Nora becomes 7 : 9.

The amount of Kate = 3x+150

The amount of Nora = 5x-150

Now,

[tex]\dfrac{3x+150}{5x-150}=\dfrac{7}{9}[/tex]

[tex]9(3x+150)=7(5x-150)[/tex]

[tex]27x+1350=35x-1050[/tex]

[tex]1350+1050=35x-27x[/tex]

[tex]2400=8x[/tex]

Divide both sides by 8.

[tex]300=x[/tex]

Putting x=300 in 3x, to get the amount of money Kate has initially.

[tex]3(300)=900[/tex]

Therefore, the Kate initially had $900.

Answer:

-2

Step-by-step explanation:

f(t) = t^2 – 2t – 2

To find f(0), replace t with 0 in the expression and evaluate the expression.

f(0) = 0^2 – 2(0) – 2

f(0) = -2

0 = t

We know this because 0 replaced t in the parenthesis next to F !

The question is just asking you to plug in 0 where ever t is!

Let's do it

[tex]f(0) = 0^{2} - 2(0) - 2[/tex]

solve

[tex]0^{2} = 0 \\2 ( 0 ) = 0[/tex]

so, this is what we have left!

[tex]f(0) = 0 - 0 - 2[/tex]

We have our answer!

[tex]f (0) = -2[/tex]
