In this problem, we have to find the factor which will make (1 / 10) equal to (2 / 5). Therefore we can write it as:

x (1 / 10) = 2 / 5

where x is the number of people who ate the blueberries

x = (2 / 5) / (1 / 10)

x = 4

 

<span>Therefore 4 people ate the blueberries.</span>

The question is about the number of people who ate blueberries. The sum of their consumption must equal to 2/5. Since each consumption is 1/10, the equation is written as

2/5 = (1/10)x
where x is the number of people who ate the blueberries
Cross-multiplying,
20 = 5x
x = 20/5 = 4

<em>Thus, there were 4 people who ate the blueberries.</em>

<h3>Answer:</h3>
  1. $2693.12
  2. $2125.00
  3. B) The area of the field is 10.24 times the area of the playground
<h3>Step-by-step explanation:</h3>

1. Each year the balance is multiplied by 1.09, so after 5 years, the balance is multiplied by 1.09^5 ≈ 1.53862395. Subtracting the original invetment amount gives the value of the interest earned.

... 5000 × 1.53862395 - 5000 = 5000 × 0.53862395

... ≈ 2693.12 . . . . matches choice D

2. The interest earned is given by the formula ...

... I = Prt . . . . .  where P is the principal, r is the interest rate, and t is the time period.

Filling in the given numbers, you have ...

... I = 2500×0.085×10 = 2125 . . . . matches choice B

3. The product of length and width is the area. If both length and width are multiplied by 3.2, then the area is multiplied by 3.2×3.2 = 10.24. The appropriate choice is B.

Sammy bought 15.3 Liters of milk. She poured the milk equally into 5 bottles. There was 0.35 liters of milk left over. Calculate
Zanzabum

Answer:

The capacity of milk in 1 bottle is 2.99 liters

Step-by-step explanation:

Let us solve the question

∵ Sammy bought 15.3 liters of milk

∵ She poured the milk equally into 5 bottles

∵ There were 0.35 liters of milk leftover

→ At first, subtract the leftover from the quantity she bought to

   find the capacity of the five bottles

∴ The capacity of the 5 bottles = 15.3 - 0.35

∴ The capacity of the 5 bottles = 14.95 liters

→ To find the capacity of each bottle divide the total capacity by 5

∴ The capacity in one bottle = 14.95 ÷ 5

∴ The capacity in one bottle = 2.99 liters

∴ The capacity of milk in 1 bottle is 2.99 liters
