Answer:

1.5m+4

Step-by-step explanation:

Let m represent the number of months.

We have been given that Svetlana's hair grows 1.5 cm per month, so in m months her hair will grow 1.5m cm.

We are also told that Svetlana's hair is 4 centimeters long, so the total length of Svetlana's hair in m months will be 1.5m+4.

Since Svetlana wants her hair to grow less than 16 cm. This means that total length of Svetlana's hair should be less than 16. We can represent this information in an inequality as:

1.5m+4

Let us solve for m.

1.5m+4-4

1.5m

\frac{1.5m}{1.5}

m

Therefore, the inequality 1.5m+4 can be used to determine the number of months, m, Svetlana can allow her hair to grow so that it is less than 16 cm long.

A dealer buys oranges for 100000, he sold 60% of them for buying price, he sold 50% of the remaining for profit of 60% then he s
suter [353]

Based on the amount of oranges bought, those sold at a profit and those sold at a loss, the overall profit is 14.2%

<h3>What is the overall profit?</h3>

Assume that the buying price was $1 each.

The amount earned from 60% of them is:

= 60% x 100,000 x 1

= $60,000

The profit from selling 50% of the remaining is:

= (50% x 40,000) x 1.60

= $32,000

The loss from selling the other 50%:

= (50% x 40,000) x 0.90

= $22,222.22

Total selling price:

= 60,000 + 32,000 + 22,222.22

= $114,222.22

Total profit:

= (114,222.22 - 100,000) / 100,000

= 14.2%

Geometry math thanks if you help
baherus [9]

Answer: Option B.

Step-by-step explanation:

For this exercise it is important to remember that, by definition, a relation is a function if and only if each input value has an unique output value.

The input values are the values of the variable "x" and the output values are the values of the variable "y".

You can observe in the table shown in the picture, that the input value -2 has two different output values:

x=-2,y=3\\\\x=-2,y=-13

Notice that the input vale -1 has two different output values too:

x=-1,y=-1\\\\x=-1,y=-9

Therefore, based on this, you can conclude that the information given in the table is a relation but not a function.
