qaws [65]

Answer:

the interest earned= 93.401

and the future value of an annuity= 493.401

Step-by-step explanation:

Given Data:

Interest rate= 7%

time,t = 3 years

weekly payment, P= 400

At the end of 3 years, final investment A= ?

n= 52 as it is weekly

As per the interest formula

A= P(1+r/n)^nt

Putting value in above equation

= 400\left(1+\frac{0.07}{52}\right)^{156}

= 493.401

Interest earned = A-P

                           = 493.401-400

                          = 93.401 !

A carton measures 3 feet by 2 feet by 2 feet. A machine can fill the carton with packing material in 3 seconds. How long would i
True [87]
1) we calculate the volume of the first carton:
volume=length x width x height
volume=3 ft * 2 ft * 2 ft=12 ft³

Therefore: 
A machine can fill 12 ft³ in 3 seconds.

2) we calculate the volume of the second carton. 
volume=length x width x heigth
volume=4 ft * 5 ft * 6 ft=120 ft³

3) we calculate the time that the machine needs for fill the second carton with packing material by the rule of three.

12 ft³---------------------3 seconds
120 ft³--------------------      x

x=(120 ft³ * 3 seconds) / 12 ft³=30 seconds.

answer: 30 seconds.
