Average weight of a package?

Mathematics

pshichka [43]3 years ago

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

Lisa [10]

Answer:

She needs the starting amount of money to create an equation.

Step-by-step explanation:

The formula that she can use when she has the starting amount or the y-intercept is this one: f(t)=P(1+b)^t.

t=time

b=percent

P=starting value

The formula with the information given is: f(6)=P(1+3.75)^6

Hope this helps!

If not, I am sorry.

What is the area of the parallelogram?<br> 15 cm<br> 21 cm<br> 20 cm
padilas [110]

Answer:

Its either 300 or 315

Step-by-step explanation:

Mainly because 20 ×15= 300 but the triangles on the side, I can't figure it out. I eliminated 82 and 420, 420 mainly because I got it wrong and 82 doesn't make sense.

A spherical hot air balloon has a diameter of 55 feet when the balloon is inflated the radius increases at a rate of 1.5 feet pe
Nuetrik [128]

Answer: 46.90mins

Step-by-step explanation:

The given data:

The diameter of the balloon = 55 feet

The rate of increase of the radius of the balloon when inflated = 1.5 feet/min.

Solution:

dr/dt = 1.5 feet per minute = 1.5 ft/min

V = 4/3·π·r³

The maximum volume of the balloon

= 4/3 × 3.14 × 55³

= 696556.67 ft³

When the volume 2/3 the maximum volume

= 2/3 × 696556.67 ft³

= 464371.11 ft³

The radius, r₂ at the point is

= 4/3·π·r₂³

= 464371.11 ft³

r₂³ = 464371.11 ft³ × 3/4

= 348278.33 ft³

348278.333333

r₂ = ∛(348278.33 ft³) ≈ 70.36 ft

The time for the radius to increase to the above length = Length/(Rate of increase of length of the radius)

The time for the radius to increase to the

above length

Time taken for the radius to increase the length.

= is 70.369 ft/(1.5 ft/min)

= 46.90 minutes

46.90mins is the time taken to inflate the balloon.
