A gallon of milk in Oregon costs $2.50. The price of a gallon of milk in Hawaii is 3 times more than the price of a gallon of mi

lk in Oregon. The price in Hawaii can be found by using the expression 3m, where m is the price of milk in Oregon. If Fernando bought a gallon of milk in Hawaii and gave the cashier a $20 bill how much change should he receive?

Answer:

Step-by-step explanation:

price of milk in Hawaii=

      3m=3 x 2.5 =7.5

change=20-7.5

           =12.5

Answer:

$12.50

Step-by-step explanation:

First, find the cost of a gallon of milk in Hawaii by multiplying 2.50 by 3:

2.5(3)

= 7.5

Then, subtract this from 20:

20 - 7.5

= 12.5

So, Fernando should receive $12.50 in change

Lunna [17]

Answer:

initial speed: 240 m/h

Step-by-step explanation:

48 m/h is the current speed which is the 20% of X

x (20 / 100) = 48

20x = 4800

x = 4800/20

x = 240 m/h

Reuben learned in art class that a mosaic is made by arranging small pieces of colored material such as glass or tile to create
anastassius [24]

Pattern is the rule that guides the formation of a set.

  • <em>The sequence of the first five mosaics is 5, 8, 11, 14, 17</em>
  • <em>The sequence is arithmetic</em>
  • <em>There are 32 tiles in the tenth mosaic.</em>

From the given design, the number of tiles used is:

T_1 = 5

T_2 = 8

T_3 = 11

<u />

<u>(a) The first five</u>

Notice that the difference in the number of tiles of successive mosaic is 3.

This means that:

T_4 = T_3 + 3 = 11 +3 = 14

T_5 = T_4 + 3 = 14 +3 = 17

So, the sequence of the first five mosaics is 5, 8, 11, 14, 17

<u>(b) The type of sequence</u>

The sequence is arithmetic

This is so, because the difference in the number of tiles of successive mosaic is 3.

This difference is called the common difference

<u>(c) The number of tiles in the tenth mosaic</u>

The nth term of an arithmetic sequence is:

T_n = T_1 + (n - 1) \times d

In this case:

T_1 = 5

d =3

n = 10

So, we have:

T_{10} = 5 + (10 - 1) \times 3

T_{10} = 5 + 9 \times 3

T_{10} = 5 + 27

T_{10} = 32

There are 32 tiles in the tenth mosaic.

I need to find all real values of x from this inequality x^2&gt;2x-2 and also this question x^2&gt;2x+2. I need the answer fast
sergeinik [125]

x^2\gt2x-2

x^2-2x+2\gt0

You are essentially asking at this point where is the quadratic function greater than 0. To get the interval find the roots. Between the roots the function is guaranteed to be LESS THAN zero. Everywhere else the function is greater than 0.

x^2-2x+2=0

Use Vieta's rule to get the roots,

(x-1)(x-1)=0

Both roots are the same so no value is less than 0 which means all values except at the point of root are strictly greater, the point of root is at x_{1,2}=1 which means the set for which the quadratic function is greater than 0 is \mathbb{R}-\{1\} "all real numbers except 1".

To convert this into interval notation use all numbers up to 1 but not including and all numbers after 1 but not including,

(-\infty,1)\cup(1,\infty)

Hope this helps :)
