In order to solve this problem, you need to know how to find averages. You do this by adding all the weights then dividing it by how many packages you have:

10 packages weighing 7.4 lbs.
12 packages weighing 8.2 lbs.
6 packages weighing 8.7 lbs

10+12+6=28 total packages

10(7.4)+12(8.2)+6(8.7)
=74+98.4+52.2
=224.6 total lbs.

Avg. = total lbs / total packages
Avg. = 224.6/28

Avg. = 8.02 lbs.

Answer:

Step-by-step explanation:

average weight can be find as;

average=sum of quantity/no. of quantity

or sum=avg*no. of quantity.

now,

first shipment has total 7.4*10= 74 pound

second shipment has total 12*8.2=98.4

third shipment has total 6*8.7=52.2

now calculating the average of all three we get.

avg=(74+98.2+52.2)/3=74.7

What is the surface area of a cone with a diameter of 28 cm. and height 22 cm in terms of Ï.

Svetlanka [38]

To find the surface area of a cone, use this formula.

pi (r) (r + [square root of h^2 plus r^2] ) substitute

h = height = 22 r = radius = 28/2 = 14 [ ] = sq. root

pi (14) (14 + [ 22^2 + 14^2 ]) solve exponents

pi (14) (14 + [484 + 196]) add

pi (14) (14 + [680]) solve square root

pi (14) (14 + 2[170]) add

pi (14) (40.0768) multiply

pi (561.075) is about 561.1 rounded to nearest tenth

So the answer is C. 561.1pi cm^2

The side RS is 7 cm. For a similar triangle, the ratio of the opposite side of the two similar triangle are the same.

<h3>What is SAS similarity theorem?</h3>

ΔABC ~ ΔDEF only if the ratio of two sides of ΔABC and corresponding two sides of ΔDEF is equal, and the angle included in both sides are congruent.

Suppose the two sides of ΔABC are AB and BC, and that of DEF be DE and EF, then for SAS similarity, we need

For the similar triangle;

$\rm \frac{HG}{TS} = \frac{FG}{RS} \\\\ \frac{12}{4} =\frac{21}{RS} \\\\ RS= 7 cm$

Hence, the side RS is 7 cm.]
