A country in South America exported 62% of the 315,000 bags of coffee beans they produced in a given year. How many bags did the
Arte-miy333 [17]

Answer:

195,300

Step-by-step explanation:

62 percent *315000 =

(62:100)*315000 =

(62*315000):100 =

19530000:100 = 195300

Now we have: 62 percent of 315000 = 195300

Question: What is 62 percent of 315000?

Percentage solution with steps:

Step 1: Our output value is 315000.

Step 2: We represent the unknown value with x.

Step 3: From step 1 above,315000=100%.

Step 4: Similarly, x=62%.

Step 5: This results in a pair of simple equations:

315000=100%(1).

x=62%(2).

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

315000/x = 100/62%

Step 7: Again, the reciprocal of both sides gives

x/315000 = 62/100

x=195300

Therefore, 62% of 315000 is 195300

Use the FOIL method to find the product below. (x + 5)(x2 – 3x)
Svetllana [295]
(x + 5)(x² - 3x)

Use FOIL (First, Outside, Inside, Last)

x(x²) = x³
x(-3x) = -3x²
5(x²) = 5x²
5(-3x) = -15x

Combine like terms:

x³ - 3x² + 5x² - 15x

x³ + 2x² - 15

x³ + 2x² - 15 is your answer
