Answer:

Option a.  2.1 inches by 1.75 inches

Step-by-step explanation:

we know that

The scale drawing is

\frac{0.5}{2.5}\ \frac{in}{ft}=0.2\ \frac{in}{ft}

That means ----> 0.2 inches in the drawing represent 1 foot in the actual

To find out the dimensions in inches of the room in the drawing, multiply the actual dimensions in feet by 0.20

so

Length: 10.5\ ft=10.5(0.2)=2.1\ in

Wide: 8.75\ ft=8.75(0.2)=1.75\ in

70 POINTS IF YOU CAN ANSWER THIS:
NNADVOKAT [17]
In any given week, salesman A earns $65 per sale, so his paycheck amounts to p_A(s)=65s (where 0\le s\le20).

Salesman B earns $40 per sale, with a weekly salary of $300, so in any given week this salesman earns p_B(s)=45s+300.

Salesman C earns a flat rate of $900 per week regardless of the number of sales, so his weekly pay is p_C(s)=900.

What is the volume of the can below? Use Pi = 3.14 and round your answer to the nearest tenth. A cylinder with height 96 millime
Serga [27]

Answer:

328,268 mm^3

Step-by-step explanation:

The can in this problem has a cylindrical shape. The volume of a cylinder can be calculated with the following formula:

V=\pi r^2 h

where

r is the radius of the base of the cylinder

h is the height of the cylinder

In this problem we have:

h = 96 mm is the height of the can

d = 66 mm is the diameter of the can

So the radius of its base is

r=\frac{d}{2}=\frac{66}{2}=33 mm

And therefore, the volume of the can is:

V=\pi (33)^2 (96)=328,268 mm^3
