The price of gas was $2.49 last month. This month, gas costs $2.79. What is
the percent increase?

Answers

2.79 - 2.49 = .30

then divide the amount increased by the original number and multiply by 100

.3 / 2.49 x 100 = 12%

Answer:

12%

Step-by-step explanation:

2.79 - 2.49 = $0.30

0.30 / 2.49 = 0.12 = 12% (decimal changes to percent)

You can check your work by doing original cost times the decimal of the percent increase. $2.49 * 0.12 = $0.30. Add this to original -> 0.30 + 2.49 = $2.79.

An expression for the nth term of another sequence is 11 – n2 (i) Find the third term of this sequence.
(ii) Find the fifth term of this sequence.

Answers

Answer:

3rd term of this sequence = 2

5th term of the sequence = -14

Step-by-step explanation:

nth term = 11 - n²

(i) Find the third term of this sequence

When n = 3

nth term = 11 - n²

3rd term = 11 - 3²

= 11 - 9

= 2

3rd term of this sequence = 2

nth term = 11 - n²

Find the fifth term of this sequence.

When n = 5

5th term = 11 - 5²

= 11 - 25

= -14

5th term of the sequence = -14

There is a a circle whose circumference is 34.54 cm.
Find the diameter of the circle. Remember use 3.14 for T.
Blank 1:

Answers

Answer:

[tex]\huge\boxed{Diameter=11cm}[/tex]

Step-by-step explanation:

Important information:

Circumference of a circle= [tex]\pi*diameter[/tex]

Method:

To work out the diameter, we would need to divide the circumference of 34.54 by pi, which in this case is 3.14, this gives us 11cm. This is because we are simply rearanging the formula of the circumference of a circle to make the diameter the subject.

Step By Step:

1) Rearange the formula to make the diameter the subject.

[tex]diameter=\frac{circumference}{\pi}[/tex]

2) Divide 34.54 by 3.14([tex]\pi[/tex]).

[tex]34.54/3.14=11cm[/tex]

Diameter

There is a a circle whose circumference is 34.54 cm. Find the diameter of the circle. Remember use 3.14 for π.

- To know the diameter divide 34.54 cm by pi (π) to get the answer.

[tex] \large \tt d = \frac{34.54}{\pi} \\ \large \tt d = 11cm[/tex]

Therefore, the diameter of the circle is 11cm

If a line passes through (6,4) and (12,7), what is the slope? I really need help and if you can please explain how you got the asnwer

Answers

Answer:

0.5 OR 1/2

Step-by-step explanation:

Since the two points are (6,4) and (12,7) you would find the distance in x and y.

Slope = change in y/ change in x

Change in y: the y coordinates are 4 and 7, so 4 + 3 = 7. +3 is the change.

Change in x: the x coordinates are 6 and 12, so 6 + 6 = 12. +6 is the change.

Slope = 3/6 = 1/2 = 0.5 = 50%

Hope this helps :D
