Lydia has 400$ in her bank account. Each week she withdraws 10$ for spending money. She also uses 5$ each week to get credit on
Softa [21]

Answer:

400 - 15x < 300

Step-by-step explanation:

We are told that she has 400$ in her bank account.

Now, Each week she withdraws 10$ for spending money. She also uses 5$ each week to get credit on her apple account.

Total total withdrawal each week = 10 + 5 = $15

If number of weeks she has been withdrawing is x, then would have withdrawn $15x after x number of weeks.

Thus, amount left after x number of weeks is:

400 - 15x

We want to find the inequality statement can be used to determine how many weeks it will take for her bank account balance to drop below 300.

Thus;

400 - 15x < 300

A cylindrical specimen of cold-worked copper has a ductility (%el) of 25%. if its cold-worked radius is 10 mm, what was its radi
loris [4]

The radius of the cylinder before deformation is 7.5mm

<h3>Deformation of an object</h3>

From the given question, we are given that;

cold work radius of the cylinder is 10mm

Ductility = 25%

Determine the radius before deformation

Radius before deformation = (1-  0.5) + 10

Radius before deformation = 0.75 * 10

Radius before deformation = 7.5mm

Hence the radius of the cylinder before deformation is 7.5mm
