Two types of barrel units were in use in the 1920s in the United States. The apple barrel had a legally set volume of 7056 cubic

babymother [125]

Answer:

Discrepancy = 665,15 L

Step-by-step explanation:

Data: 1 Apple Barrel: 7056 cubic inches

1 Cranberry Barrel: 5826 cubic inches

The merchant sells 33 cranberry barrels, so we need to find out the total volume of that. So we multiply our cranberry volume (data) 33 times:

33 x 5826 cubic inches = 192258 cubic inches

Now, the customer thinks that he is receiveing apple barrels. To calculate this volume, we need to multiply the apple volume (data) 33 times:

33 x 7056 cubic inches = 232848 cubic inches

(You can see that 33 apple barrels have more volume that 33 cranberry barrels, so the customer will receive less volume than he is expecting)

The problem is asking the discrepancy in the shipment in liters (L). First we calculate the discrepancy (difference) in cubic inches.

Discrepancy (cubic inches) = 232848 cubic inches - 192258 cubic inches = 40590 cubic inches

Finally we need to transform the units. As a general rule, we know that:

1 litre (L) = 61,0237 cubic inches. Using a simple rule of three we can solve it:

Discrepancy (L) = $\frac{40590 cubic inches}{61,0237 cubic inches\\}$ x 1 L

Discrepancy (L) = 665,15 L

You are making a recipe that calls for cream of mushroom soup. There is a deal at the store, where you can buy 10 cans of soup f

Olenka [21]

Answer:

The cost of 6 cans of soup = $7.8

Step-by-step explanation:

The cost of 10 cans of soup = $13

The number of cans needed for the soup = 6

Now, Cost of 1 can of soup = $\frac{\textrm{Total cost of 10 cans of soup}}{\textrm{10}}$

= $13 / 10 =$1.3

⇒The cost of 1 can of soup is $1.3

Now, The cost of 6 cans of soup = 6 x Cost of 1 can

⇒ 6 x $1.3 = $7.8

Hence, the cost of 6 cans of soup = $7.8

6 Find the equivalent ratio for 64%. Write your answer in simplest form.

Snowcat [4.5K]

solution

Find the equivalent ratio for 64%. Write your answer in simplest form.

For this case we can do the following:

64% = 64/100

And if we simplify we got:

64/100 = 32/50 = 16/25 = 0.64

Country A has a growth rate of 4.9% per year. The population is currently 4 comma 151,000, and the land area of Country A is 1

kvv77 [185]

Answer:

There will be one person on 1 square yard of land after 1,892,147.588 years.

Step-by-step explanation:

Continuous exponential growth formula:

$P(t)=Pe^{rt}$

P(t)= Population after t years.

P= Initial population

r=rate of growth.

t= time in year

Given that,

Growth rate of country A (r)= 4.9% per year=0.049 per year.

Initial population (P)= 151,000.

Land area of country area= 14,000,000,000 square yards.

There will be one person on one square yard of land.

So, there will be 14,000,000,000 person for 14,000,000,000 square yard of land in country A.

P(t)=14,000,000,000 person

$\therefore 14,000,000,000= 151,000 e^{0.049t}$

$\Rightarrow e^{0.049t}=\frac{ 14,000,000,000}{ 151,000}$

Taking ln both sides

$\Rightarrow ln|e^{0.049t}|=ln|\frac{ 14,000,000,000}{ 151,000}|$

$\Rightarrow {0.049t}=ln|\frac{ 14,000,000,000}{ 151,000}|$

$\Rightarrow t}=\frac{ln|\frac{ 14,000,000,000}{ 151,000}|}{0.049}$

$\Rightarrow t}=1,892,147.588$ years

There will be one person for every square yard of land after 1,892,147.588 years.
