Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent.

A pair of triangles are said to be similar if two pairs of corresponding angles in those triangles are congruent. We can conclude that the third pair must also be equal if the first two angle pairs are. When all three pairs of angles are equal, the sides of the three triangles must also be proportionate.

If a certain missing number will result in the expression 20x +24 when using the distributive property, then the number that must be multiplied by (5x + 6 ) to result in the expression 20x + 24  is 4.

The distributive property is a property of multiplication, according to which if two or more values that are added together are multiplied by a number, then the result will be the same if each of these values is multiplied separately with that number and then the products are added together.

Considering y to be the number that must be multiplied by (5x + 6),

y (5x + 6) = y(5x) + y(6)

As the expression is,

20x + 24

y(5x) = 20x and y(6) = 24

6y = 24

y = 24 ÷ 6

y = 4

This can be confirmed as follows,

y(5x) = 20x

Putting y = 4 in this equation,

4(5x) = 20x

Hence the number that must be multiplied by (5x + 6) to result in the expression 20x + 24 is calculated to be 4.

The coordinates of point P are ( -3.5, 2.25).

Given points L( -6, 5) and M( 4, - 6). We are to determine the coordinate of point P that lies along the directed line segment which partitions the segment in the ratio of 1 to 3.

The coordinates of the point that divides a line segment internally in the ratio m:n are given as follows:

[ (mx₂ + nx₁ ) / (m + n) , (my₂ + ny₁ ) / (m + n) ]

Now, m : n = 1 : 3

( x₁, y₁ ) = L( - 6 , 5 )

( x₂, y₂ ) = M( 4, - 6 )

Therefore,

P( x, y) =  [ ( 1 × 4 + 3 × -6 ) / 4 , ( 1 × - 6 + 3 × 5) / 4 ]

P( x, y) = [ ( 4 - 18 ) / 4 , ( - 6 + 15) / 4 ]

P( x, y ) = [ -14/4 , 9/4 ]

P( x, y) = ( - 7/2 , 9/4 )

Step-by-step explanation:

Step-by-step explanation:

1 km = 1000 m = 0.621371 miles

so,

786.3 m = 0.7863 km (simply divide by 1000).

40 km/h = 40×0.621371 mph (as the reference of 1 hour stays the same).

= 24.8548 mph

always consider the direction of the conversion rate : are you going from a smaller to a larger unit, or from a larger to a smaller unit ?

if we would have said

1 m = 0.001 km

then we would have converted 786.3 m by multiplying it by 0.001 (also getting 0.7863 km as result, of course).

but because we defined it the other way around, we had to divide by 1000. it is clear that this is the same operation, yes ?

in the same way, if we would have said

1 mile = 1.60934 km

then we would have converted 40 km to miles by dividing 40 by 1.60934. again getting the same result, of course.

The length of the segment MN is 9.5 units

The endpoints of the line segment MN are given as

M = (-2, -2)

N = (7, -5)

The length of the segment MN is calculated as:

MN = √(x2 - x1)^2 + (y2 - y1)^2

Substitute the known values in the above equation

So, we have

MN = √(-2 - 7)^2 + (-2 + 5)^2

Evaluate the sum and the difference

So, we have

MN = √-9^2 + 3^2

Evaluate the exponents

So, we have

MN = √81 + 9

Evaluate the sum

So, we have

MN = √90

Evaluate the exponents

So, we have

MN = 9.5

The factors of equation are -4 and -5.

Rewriting the equation -

x² + 9x + 20 = 0

ax² + bx + c = 0

The mentioned equation will be factorized using the given two rules -

1. sum of the factors will be equal to numeral in middle expression b (9x in this case)

2. product of factors will be equal to product of a and c (20 in this case)

Using above rules, the appropriate factors should be 5 and 4.

Representing the factors in mentioned equation -

x² + 4x + 5x + 20 = 0

Taking common factors

x(x + 4) +5(x + 4) = 0

(x + 4) (x + 5) = 0

x = -4, -5

Hence, the two factors of given equation are -4 and -5.

To check the answer, we will keep each value of x in  the equation -

When x = -4

x² + 9x + 20 = 0

(-4)² + 9(-4) + 20 = 0

A diver starts at 5 m and changes -16 m. What depth is he now?

Given that angle E and angle F are supplementary, the numerical measure of angle F is 74°.

Supplementary angles are angles that sum up to 180 degrees.

Given the data in the question;

Since E and F are supplementary, it means they sum up to 180 degrees.

Measure of angle E + Measure of angle F = 180°

Plug in the given values and solve for x

( 9x - 38 ) + ( 2x + 42 ) = 180

9x + 2x - 38 + 42 = 180

11x + 4 = 180

11x = 180 - 4

11x = 176

Divide both sides by 11

11x = 176

11x/11 = 176/11

x = 16

Now, the numerical measure of angle F will be;

Measure of angle F = ( 2x + 42 )

Measure of angle F = 2( 16 ) + 42

Measure of angle F = 32 + 42

Measure of angle F = 74°

Given that angle E and angle F are supplementary, the numerical measure of angle F is 74°.

The scaling factor is 2: 1, the distance between Q and S is 3 units.

A scale factor is a number or conversion factor used to adjust the size of a figure without changing its shape. It is used to enlarge or reduce the size of an object. If the original dimensions are known, the scaling factor may be determined.

When describing a shape, you must define the amount to which it has been enlarged.

AC = 6

It signifies that the 6/3 = 2:1 scale factor has been preserved.

As a result, the total dimension of PQRS is half of ABCD.

So,

QS = 1/2 (BD)

Because BD = 6, (can be counted by graph grid)

So,

QS = 1/2 (5) = 3

Hence "Because the scale factor is 2: 1, the distance between Q and S is 3 units."

Find the least common multiple (LCM) of the denominators in order to find the least common denominator (LCD).

If Gil traveled 4. 5 miles and continues at a speed of 62.5 miles per hour and Andy has traveled 29.5 miles and continues at a speed of 50 miles per hour, then the number of hours it will take for Andy and Gill to travel the same number of miles is equal to 2.

The number of hours it will take for Andy and Gill to travel the same number of miles can be determined by using an algebraic expression.

An algebraic expression to find the number of hours can be given as,

4.5 + 62.5(x) = 29.5 + 50(x)

Here, x is equal to the number of hours.

Solving to find the value of x,

62.5x - 50x = 29.5 - 4.5

12.5x = 25

x = 25 ÷ 12.5

x = 2
