Help plz #8 solve the inequality<img src="https://tex.z-dn.net/?f=10%20%2B%20c%20%5Cgeq%2011" id="TexFormula1" title="10 + c \ge

Orlov [11]

The answer is c ≥ 1

Subtract 10 on both sides.

11-10= 1

and that’s how u get ur answer, hope this helped :)

It takes 40 ink cartridges and 200 pages to print a book, and it takes 30 ink cartridges and 80 pages to print a magazine. Sarah

denis-greek [22]

Answer:

It takes 40 cartridges per book (B) and 30 cartridges per magazine (M) and Sarah wants to use at most 300 cartridges.

.. 40B +30M ≤ 300

It takes 200 pages to print a book and 80 pages to print a magazine and Sarah wants to use at most 1200 pages.

.. 200B +80M ≤ 1200

Hope this helped!

Is 10% of 10% of 100 the same as 20% of 100?

Lelu [443]

No;

20% of 100 = 0.20 x 100 = 20
10% of 10% of 100 = 0.10 x 0.10 x 100 = 1

The volume of both of these trapezoidal prisms is 24 cubic units. Their heights are 6 and 8 units, as labeled. What is the area

Ne4ueva [31]

Answer:

area of a trapezoidal base of each prism with heights 6 and 8 units are 4 square units and 3 square units respectively

Step-by-step explanation:

Let us first be aware of formula of volume for any regular geometrical figure.

Fundamental formula for volume for any regular geometrical figure is.

volume = area of cross section of object* height of object (A)

In the problem stated area of cross section of object will be area of a trapezoidal base.

Given in the question is

Volume of both the trapezoidal prisms = 24 cubic units

*************************************************************************************

For prism with height 6 unit

Substituting the value of height and volume in formula for trapezoidal prisms

24 = 6 * area of a trapezoidal base

=> area of a trapezoidal base = 24/6 = 4 square units

*************************************************************************************

For prism with height 8 unit

Substituting the value of height and volume in formula for trapezoidal prisms

24 = 8 * area of a trapezoidal base

=> area of a trapezoidal base = 24/8 = 3 square units

*************************************************************************************

Therefore area of a trapezoidal base of each prism with heights 6 and 8 units are 4 square units and 3 square units respectively.
