Answer:

The expected number of children to attend the concert  is 143.

Step-by-step explanation:

The total guest expected to attend the concert = 200

Here, Ratio of Adults: Children = 2: 5

Let us assume the common factor in the given ratio  = m

So, the expected number of adults to attend the concert  = 2 m

Also, the expected number of children to attend the concert  = 5 m

Number of (Adults + Children) attending concert  = 200

⇒ 2 m +  5 m = 200

or, 7 m = 200

or,  m = 200 /7 = 28.57

or, m  = 28.57

Now, the expected number of children to attend  = 5 m

= 5 x 28.57 = 142.85 ≈ 143

Hence, the expected number of children to attend the concert  is 143.

Answer:

  • 1. Interest: $166.67

           Principal: $6,166.67

  • 2. Interest: $200.00

            Principal: $5,200.00

Explanation:

<u><em>1. $6000 for 50 days at 20% p.a</em></u>

<u><em></em></u>

In 20% pa, pa means "per annum", i.e. "per year".

Assume simple interest:

  • Principal: $6,000
  • interest: 20% pa
  • time = 50 days

Interest:

  • Interest = Principal × number of days × annual rate / 360

  • Interest = $6,000 × 50 × 20% / 360 = $166.67

Principal = principal + interest = $6,000 + $166.67 = $6,166.67

<u><em></em></u>

<u><em>2. $5000 for 5 months at 0.8% per month</em></u>

Assume, again, simple interest.

  • Principal: $5,000
  • interest: 0.80% per month
  • time = 5 months

Interest:

  • Interest = Principal × number of months × montly rate

  • Interest = $5,000 × 5 × 0.80%  = $200.00

Principal = principal + interest = $5,000 + $200.00 = $5,200

You can see that the accrued interests depend on the principal, the interest rate, and the time.

cupoosta [38]

Answer:

50%

Step-by-step explanation:

Actual value - estimated value

Actual value = 24 miles

Estimated value = 36 miles

Estimated value - Actual value

= 36 miles - 24 miles

= 12 miles

% error = change in value / actual value × 100

= 12/ 24 × 100

= 1/2 × 100

= 50%

% error = 50%
