A worker at a mill is loading 5 pound bags of flour into boxes to deliver to a local warehouse. Each box holds 16 bags of flour. If the warehouse orders 4 tons of flour how many boxes are needed to fulfill the order ?

Answers

Answer:

100

Step-by-step explanation:

volume of 16 bags of flour: 16 x 5 = 80 pounds

We know that: 1 ton = 2,000 pounds -> 4 tons = 2,000 x 4 = 8,000

So we need: 8,000 : 80 = 100 boxes to fulfill the order

A sailboat depreciates at 15% of its original value each year. If the sailboat was $9500 at its time of purchase, what is the value of the sailboat after 7 years?

Answers

The sailboat would be fully depreciated when the 7th year comes when it was depreciated 15% every year. This is because when you try to multiply 15% by 7 it would give you 105%, it already exceeds the 100% value of the sailboat.

Dante and Mia have a total of 350 pennies in their piggy banks, altogether. After Dante lost half of his pennies and Mia lost one third of her pennies, they both had an equal amount of pennies left. How many pennies did they lose altogether?

Answers

Answer:

150 pennies were lost altogether

Step-by-step explanation:

Let the initial number of pennies owned by Dante be x pennies

Let the initial number of pennies owned by Mia be y pennies

Mathematically ;

x + y = 350 •••••••(i)

So after losing half, dante will have x/2 pennies left.

Mia lost 1/3 so she will have 2/3y left

So after all the losses, they both had equal amount of pennies

This means that;

x/2 = 2y/3

Cross multiply;

3x = 4y •••••••(ii)

Let’s solve both equations simultaneously;

From i , x = 350-y

Substitute this into equation ii

3(350-y) = 4y

1050-3y = 4y

7y = 1050

y = 1050/7

y = 150

since x = 350-y

x = 350-150 = 200

Now Dante loss x/2 = 200/2 = 100

Mia lost 1/3y = 1/3 * 150 = 50

Total pennies lost = 100 + 50 = 150

Final answer:

The given pattern is a mathematical sequence where each number is obtained by multiplying the previous number by 9 and subtracting 1. The solution to the pattern is 8, 72, 647, 5822, 52499.

Explanation:

The given pattern is a mathematical sequence where each number is obtained by multiplying the previous number by 9 and subtracting 1. The pattern continues by multiplying the new number by 9 and subtracting 1 again.

Let's break down the steps for each number in the sequence:

1 x 9 - 1 = 8
8 x 9 - 1 = 72
72 x 9 - 1 = 647
647 x 9 - 1 = 5822
5822 x 9 - 1 = 52499

Therefore, the solution to the given pattern is 8, 72, 647, 5822, 52499.
