Denise would like to purchase a computer that costs$2000. Create and solve an inequality in order to determine the least amount
photoshop1234 [79]

The question is incomplete. Here is the complete question:

Denise earns $30 an hour. She wants to purchase a computer that costs $2000. Create and solve an inequality to determine the least amount of hours she must work in order to be able to purchase the computer.

Answer:

30h\geq 2000\ or\\h\geq67

Denise has to work at least 67 hours in order to buy a computer that costs $2000.

Step-by-step explanation:

Given:

Hourly earning of Denise is $30.

Let the number of hours Denise works be 'h'.

Now, total earning of Denise can be calculated using the unitary method and is given as:

Total\ money=\textrm{Hourly earning}\times \textrm{Total hours worked}\\Total\ money=30\times h\\Total\ money=30h

Now, total money earned by Denise must be at least $2000 in order to purchase a computer. Therefore, the inequality is given as:

30h\geq 2000\\h\geq \frac{2000}{30}\\h\geq 66.7

Therefore, Denise has to work at least 67 hours in order to buy a computer that costs $2000.

When is a rhombus a rectangle?
Alinara [238K]
Check the picture below.

a rhombus is a quadrilateral with all equal sides.

now, the sides do not have to be slanted, but they must be equal, IF it happens that all sides meet at right-angles, then the rhombus is a "rectangle", due to its right-angleness, incidentally enough, since all sides are equal, if that ever happens, it also becomes a square.

Help please I don’t understand it show work
melomori [17]

Step-by-step explanation:

Here you solve for length width and height, which multiplied equal volume. The only constant you have is that the width of the prism is 1/3 of its length.

WIDTH: 3 centimeters

LENGTH: Since the width is 1/3 of the length, 3 is 1/3 of something. So divide 3 by 1/3 to get 9. You can also just multiply 3 by 3.

HEIGHT: The height is half of the width, which is 3. Therefore 3 divided by 2 is 1.5.

Now multiply the values. 3 multiplied by 9 multiplied by 1.5

The answer is 40.5

CENTIMETERS!!!
