Based on the information given, the value of line RT is 36

What is a line segment?  

A line segment can be defined as the part of a straight line bounded by two distinct end point

It also contains every point on the line between its endpoints.

From the information given, we have line PT is a line with segments PR and RT and R is the point between P and T

This can be represented as;

PR + RT = PT

Where;

PR = 3xRT = 2x + 24 PT = 54

Substitute into the equation;

3x + 2x + 24 = 54

collect like terms

5x = 54 - 24

5x = 30

Make 'x' the subject of formula

x = 30/ 5

x = 6

But;

RT = 2x + 24

RT = 2(6) + 24

RT = 36

A certain missing number will result in the expression 20x +24 when using the distributive property. what number must be multiplied by (5x +6) to result in the expression 20x+24

Answers

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.

What are the coordinates of the point P that lies along the directed
segment from L(-6, 5) to M (4, -6) and partitions the segment in
the ratio of 1 to 3?

Answers

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 )

Answer:

The shortest distance from A to C is 102.89 m.

What is Perimeter?

Perimeter refers to the total distance around the boundary of a two-dimensional shape. It is the sum of the lengths of all the sides of the shape.

Using Pythagoras theorem

AC² = 50²+80²

AC² =8900

AC =√8900

AC = 94.33

So, the distance removing the diameter

= 94.33-15

= 79.33

Now, Circumference of semicircle = πr

= 23.56 m

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.

MN¯has an endpoint at M(–2, –2) and an endpoint at N(7, –5).

What is the length of MN to the nearest tenth?

Answers

The length of the segment MN is 9.5 units

How to determine the length of the segment MN?

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

Harry needs to pay $ 125.55 in total for the 9.0 pizzas he ordered at $ 13.95 each.

To calculate how much Harry needs to pay, multiply the number of pizzas (9.0) by the cost of each pizza ($ 13.95).

Total cost = Number of pizzas × Cost per pizza

Total cost = 9.0 × $ 13.95

To find the product, we can treat 9.0 as a whole number and then multiply:

Total cost = 9 × $ 13.95

Now, calculate the product:

Total cost = $ 125.55

Harry needs to pay $ 125.55 in total for the 9.0 pizzas he ordered at $ 13.95 each.

Answers

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

Hence, the number of hours it will take for Andy and Gill to travel the same number of miles is calculated to be 2.

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

What is the numerical measure of angle F?

Supplementary angles are angles that sum up to 180 degrees.

Given the data in the question;

E and f are supplementaryMeasure of angle E = ( 9x - 38 )°Measure of angle F = ( 2x + 42 )°Numerical measure of angle F = ?

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°.
