6 x (-13) = -78

x - 5 = -78

x = -78 + 5

x = -73

Answer:

$40.25

Step-by-step explanation:

15% = 0.15, so multiply 35 * 0.15 = 5.25 to get the tip.

Since the answer is asking for both the tip and the cost, add 35 + 5.25, which gives the answer $40.25

The area of the sector which is the white triangle adding the shaded region is 68.9/360*π*9.28^2=51.78005(rounding to 5th digit after decimal point for accuracy before we do final round for answer)

The area of the white triangle in the sector has area 1/2*9.28^2*sin(68.9)= 40.17223(rounding to 5 digits again for some accuracy.

Now we take out the white triangle from the sector.

51.78005-40.17223=11.60782

rounding to the nearest tenth we get 11.6 cm^2

Problem done!

Answer: Q(n) = Q(n - 1) + 2.5

Step-by-step explanation:

We have 3 values of the sequence Q(n)

These values are:

Q(1) = 3

Q(3) = 8

Q(7) = 18

I would think that this is a geometric sequence.

Remember that the equation for the n-th term of a geometric sequence is:

A(n) = A(1)*r^(n-1)

where r is a constant, and A(1) is the first term of the sequence.

If we rewrite the terms that we know of Q(n) in this way we get:

Q(3) = Q(1)*r^(3 - 1) = 3*r^2 = 8

Q(7) = Q(1)*r^(7 - 1) = 3*r^6 = 18

Then we have two equations:

3*r^2 = 8

3*r^6 = 18

We should see if r is the same for both equations:

in the first one we get:

r^2 = 8/3

r = (8/3)^(1/2) = 1.63

and in the other equation we get:

r^6 = 18/3

r = (18/3)^(1/6) = 1.34

Then this is not a geometric sequence.

Now let's see if this is an arithmetic sequence.

The n-th term of an arithmetic sequence is written as:

A(n) = A(1) + (n - 1)*d

where d is a constant.

If we write the terms of Q(n) that we know in this way we get:

Q(3) = Q(1) + (3 - 1)*d = 3 + 2*d = 8

Q(7) = Q(1) + (7 - 1)*d = 3 + 6*d = 18

We need to see if d is the same value for both equations.

in the first one we get:

3 + 2*d = 8

2*d = 8 - 3 = 5

d = 5/2 = 2.5

In the second equation we get:

3 + 6*d = 18

6*d = 18 - 3 = 15

d = 15/6 = 2.5

d is the same for both terms, then this is an arithmetic sequence.

An arithmetic sequence is a sequence where the difference between any two consecutive terms is always the same value (d)

Then the recursive relation is written as:

A(n) = A(n - 1) + d

Then the recursive relation for Q is:

Q(n) = Q(n - 1) + 2.5

Graph is a way to represent a lot of data in a visual formal. The graph that best represents the student's walk is graph A.

A graph is a way to represent a lot of data in such a visual formal that it is easy for the user to understand the complete information in one go. Usually, the line of the graph is a function that follows the graph.

As we can see that the y-axis of the graph represents the distance traveled by the student while, the time taken by the student to cover the distance is given on the x-axis.

We know that the rate of 1.5 meters per second, means that the student will cover the 1.5 meters in 1 second, therefore, the line will be a slope that will represent the walk of the student. At time t=4 seconds, a student stopped for 4 seconds therefore, the time will increase but the distance will be constant for the student, therefore, the situation will be represented by a horizontal line.

Hence, the graph that best represents the student's walk is graph A.

Answer:

94

Step-by-step explanation:

the sum of the angles in a triangle add up to equal 180

180-73-13=94

Answer: X = 89°

Step-by-step explanation:

At first glance I could tell this was an isosceles triangle, the angles of an isosceles triangle add up to 180°. So just add 73° + 13° = 91° so then you subtract 91° from 180° and you get 89°.

Answer: 30 + 45 = 15(2 + 3)

Step-by-step explanation:

The greatest common factor for 30 and 45 will be gotten as follows:

Factor of 30 = 2 × 3 × 5

Factor of 45 = 3 × 3 × 5.

GCF = 3× 5 = 15

Therefore, the equation that shows how to rewrite the sum of 30 and 45 using their greatest common factor will be:

30 + 45 = 15(2 + 3)

Answer:

Onaje is correct.

Step-by-step explanation:

To start, total up how many shirts we have, and multiply them by t. Since they are the same price, we now have a total for how many shirts they bought. This proves the second and third equations that they wrote. If you take the easy way and just add them, you'll still have 25t, making Onaje's expression correct.

EDIT: Just saw you need why it's incorrect for Paula, just hold on.

So for Paula, it's simple why she is incorrect. If you look at the third equation she wrote, she's adding 25 to 2t, which is completely incorrect, and will come up with a different result than 16t + 9t.
