Answer:

Step-by-step explanation:

Alright, lets get started.

Lets split the given graph in three parts.

First part: 0 to 30 minutes

We can see between this period, 0 to 30 minutes, the distance from home keeps increasing. It means from 0 to 30 minutes, Eli is moving towards the library.

Second part: 30 to 120 minutes

between 30 to 120 minutes,the distance from home does not changes. It means during this period, Eli is at the library.

Third part : 120 minutes to 135 minutes

Between 120 to 135 minutes, the distance from home is decreasing.

It means Eli is returning home in that period.

It means, at 120minute, Eli started her bicycle , home from the library. Hence option (b) : Answer

Hope it will help :)

AveGali [126]

Answer:

Barbados won the Bronze.

Step-by-step explanation:

The information indicates that Jamaica finished before Barbados, but behind Trinidad which means that Trinidad was the first one, then Jamaica and the third one was Barbados:

1. Trinidad

2. Jamaica

3. Barbados

Then, it indicates that Haiti finished before Guyana, but behind Barbados which indicates that Haiti was in 4th place after Barbados and the last one was Guyana:

1. Trinidad

2. Jamaica

3. Barbados

4. Haiti

5.Guyana

According to this, the answer is that Barbados won the Bronze.

Given: m angle P equals open parentheses 5 x minus 27 close parentheses degree, m angle Q equals open parentheses 4 x minus 7 cl

max2010maxim [7]

Answer: Side QR

Step-by-step explanation: The sum of a triangle internal angles is 180°. So to determine the angles, we calculate x:

5x - 27 +4x - 7 + 3x + 10 = 180

12x = 204

x = 17

With x, solve for the angles:

m∠P = 5(17) - 27 = 58

m∠Q = 4(17) - 7 = 61

m∠R = 3(17) + 10 = 61

The relationship between angles and sides in any triangle:

the largest angle is opposite the largest side;
the middle angle is opposite to the middle-sized side;
the shortest angle and side are opposite to each other;

So, the shortest side of PQR is the side opposite to the shortest angle.

The shortest angle is m∠P = 58°. Therefore, the shortest side is QR

1. How do you prove congruence through transformations?

konstantin123 [22]

One can prove congruence through transformation if they have the same shape and size.

The congruency postulates include:

SSS - Side-Side-Side
SAS - Side-Angle-Side
ASA- Angle-Side-Angle
AAS - Angle-Angle-Side
RHS - Right angle-Hypotenuse-Side

<h3>What is congruence?</h3>

In geometry, it should be noted that two figures are congruent if they have the same shape and size.

In this case, if two angles and a non-included side of one triangle are equal to two angles and a non-included side of another triangle, then the triangles are congruent.

One can prove triangle congruence using congruency postulates by using the SSS theorem( side side side theorem).

It should be noted that the congruence postulate is used to illustrate that the triangles are equal.

Idek why brainly deleted my last one but-<br><br><br>solve for x<br><br>2/3x - 4 1/2 = -8

BaLLatris [955]

Answer:

The answer is x= -5 1/4

Step-by-step explanation:

Let's solve your equation step-by-step.

2/3x−4 1/2=−8

Step 1: Simplify both sides of the equation.

2/3x+−9/2=−8

Step 2: Add 9/2 to both sides.

2/3x+−9/2+9/2=−8+9/2

2/3x=−7/2

Step 3: Multiply both sides by 3/2.

(3/2)*(2/3x)=(3/2)*(−7/2)

x=−21/4

Answer:

x= −5 1/4
