Answer:
1152 tons of grains
Step-by-step explanation:
We are told in the above question:
Total number of grains = 1440 tons of grain
On the second day 80 percent of the amount of the amount of the grain delivered during the first day where brought in.
Hence,
The number of grains brought in during the first day = 80% × 1440 tons
= 80/100 × 1440 tons
= 1152 tons of grains
The sum of the first 28 terms in the sequence is 5600
<h3>Sum of sequence</h3>
The sum of sequences are known as series. Given the following
a₁ = 92
a₁ = ai-1 - 8
For the second term
a2 = a1 - 8
a2 = 92 - 8
a2 = 84
Determine the sum of first 28th terms
S28 = 28/2[2(92)+(28-1)(8)]
S28 = 14(184+27(8))
S28 = 14(400)
S28 = 5600
Hence the sum of the first 28 terms in the sequence is 5600

For this case we have to:
x: It is the variable that represents the number of compact discs.
The cost function must be found considering that each disk costs $7.13. So:
Thus, to find the total cost of "x" compact discs (in $) we substitute the number of discs in the cost function.
Answer:
Multiply by the reciprocal scale factor. in other words multiply 48 x 6 and you should get 288 ft. ^2
