Based on the statements provided, Barry will a have a Labrador, a Collie and a Staffie at home if he has at least one dog breed.

<h3>What is logical reasoning ?</h3>

Logical reasoning in mathematics is the process of using rational and critical thinking abilities to arrive at a conclusion about a problem.

Since Barry have at least one dog breed, the possible breeds of dogs that Barry have can be determined as follows:

Statement 1: If I have a Labrador but not a Staffie, I also have a Collie

Statement 2: I either have both a Collie and a Staffie or neither.

Statement 3: If I have a Collie, then I also have a Labrador.

From Statement 1, If Barry will have a Labrador and Collie if he doesn't have a Staffie.
From Statement 2, Barry will have both a Collie and a Staffie or he wont have either.
From Statement 3, Barry must have a Labrador if I he has a Collie.

Therefore, Barry will have a Labrador, a Collie and a Staffie at home if he has at least one dog breed.

What is 34 tens + 20 tens =

FromTheMoon [43]

34 tens + 20 tens = ?

1 ten = 10 ones or 10.

34 + 20 = 54
54 tens
34 tens + 20 tens = 54 tens

54 × 10 = 540

34 tens + 20 tens = ?
34 tens + 20 tens = 54 tens
34 tens + 20 tens = 540

Answer:

It may be 9

Step-by-step explanation:

Solution:

Here,

Median = n+1/2th term

=5+1/2 th term

=6/2 th term

=3rd term

Now,

Arranging the data in ascending order...

6,8,9,10,12

Since, 9 is the third term. So, 9 is the median.....

Drag and drop a statement or reason to each box to complete the proof.

bazaltina [42]

Answer:

1. MN≅QP

MQ≅NP

2. MP≅MP

3. SSS congruence postulate

4. ∠N≅∠Q

5. CPCTC

Step-by-step explanation:

1. As per the property of parallelogram that opposite sides are congruent, in given case of parallelogram MNPQ the opposite sides

MN≅QP and MQ≅NP.

2. The reflexive property of congruence states that a line or a geometrical figure is reflection of itself and is congruent to itself. Hence in given case of parallelogram MNPQ

MP≅MP

3. SSS congruence postulate stands for Side-Side-Side congruence postulate, it states that when three adjacent sides of two triangle are congruent then the two triangles are congruent. In given case of parallelogram MNPQ, as the sides MN≅Q, MQ≅NP and MP≅MP hence

ΔMQP≅ΔPNM

5. As proven in part 4 that ΔMQP is congruent to ΔPNM, so as per the property of CPCTC (congruent parts of congruent triangles are congruent)

∠N≅∠Q

5. CPCTC stands for congruent parts of congruent triangles are congruent.

Which system of equations is graphed below? On a coordinate plane, a line goes through (0, 1) and (4, negative 2) and another go

natulia [17]

Answer:

The correct option is (B)

(B) x-y = 6 , 3x+4y = 4

Step-by-step explanation:

As we can see in the graph given below, both lines intersect at (4, -2), which should be the solution of given equations:

Find the values of x and y for (B);

x - y = 6 ⇒ (i)

3x + 4y = 4 ⇒ (ii)

Lets consider equation (i)

x - y = 6

x = 6 + y

Substitute in equation (ii)

3(6+y) + 4y = 4

18 + 3y + 4y = 4

7y = -14

y = -2

Substitute in equation (i)

x - (-2) = 6

x + 2 = 6

x = 6 - 2

x = 4

As solution of part C is also (4, -2), it represents the graph

You can also find the (x, y) for other options the similar way, which will show you they don't have the same value
