The surface area of the pencil is the amount of space it covers

The surface area of the pencil is 61 square centimeters

<h3>How to determine the surface area?</h3>

The given parameters are:

H = 20 cm

L = 0.5 cm

The surface area (SA) is then calculated as:

SA = 6LH + 3 $\sqrt 3$ L^2

This gives

SA = 6 * 0.5 * 20 + 3 $\sqrt 3$ * 0.5^2

Evaluate the sum

SA = 61

Hence, the surface area of the pencil is 61 square centimeters

7-ounce package costs $2.59. A 12 ounce package costs $4.56. An 18 ounce package costs $6.30. Which package is the best buy?

Yanka [14]

Answer:

18 ounce package for $6.30

Step-by-step explanation:

For each one, you divide the money by the package to see how much it is per ounce.

2.59 / 7 = $0.37 per oz

4.56 / 12 = $0.38 per oz

6.30 / 18 = $0.35 per oz

Find the area under the standard normal curve to the left of z=1.25.

snow_tiger [21]

For quite some time now, calculators have had statistical functions built in. Here we need to use the stat. function normalcdf, which has only two inputs when we're working with z scores instead of raw scores.

Here,

normalcdf(-100,1.25) = 0.894

This same result could be obtained using a table of z-scores.

What two numbers add to 9 and multiply to negative 11

fiasKO [112]

The two numbers are (9+ 5√5)/2 and (9- 5√5)/2.

(9+ 5√5)/2+ (9- 5√5)/2= 9
(9+ 5√5)/2* (9- 5√5)/2= -11

Hope this helps~
