Sharon is decreasing the size of a diagram of a leaf that is 30 centimeters long by 10 centimeters wide, if the reduced diagram
sertanlavr [38]

Answer:

12 cm


Step-by-step explanation:

This is a proportionality/similarity problem.

10 cm turned to 4 cm. So by how much has it decreased? In other words, <em>10 multiplied by </em><em>WHAT</em><em> is 4?</em>

10*x=4\\x=\frac{4}{10}\\x=0.4

0.4 is also known as the scale factor from the large diagram to the small diagram.

So how much would 30 cm become?<em> It would be 30 multiplied by the scale factor, which is </em><em>0.4</em><em>.</em>

30*0.4=12

<u>Hence, the length of the reduced diagram would be </u><u>12 cm</u><u>.</u>

Solve for x under the assumption that x&lt;0. <br> x-5/x&lt;4
AleksandrR [38]
If you would like to solve the inequality x - 5/x < 4, you can do this using the following steps:

<span>x - 5/x < 4
</span>x^2 - 5 < 4x
x^2 - 4x - 5 < 0
(x - 5) * (x + 1) < 0
x < 0
1. x = 5
2. x = -1

The correct result would be x = -1.

A mathematics Teacher brought 40 expensive calculator at 16400 each and a number of cheaper calculator costing tshs 5900 each. S
Novay_Z [31]

Answer:

20

Step-by-step explanation:

First, let's find how much she spent on the expensive calculators

40 times $16400= $656,000

Now, lets find how much money she had for the cheap calculators.

$774,000- $656,000=$118000

Now that we have her budget (money remaining) for the cheaper calculators, lets divide that by the price for each individual calculator.

$118000/$5900=20

If you like my answer, please mark me as a brainliest! (I am new to this community.)
