Answer:

  8

Step-by-step explanation:

Since there are 3 (an odd number) ages, the median is the middle one. So, we know two of the ages are 10 and 15. In order for the mean of the three ages to be 11, their total must be 33. The total of the two known ages is 25, so the remaining one must be ...

Answer:

273 square feet

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Total ceiling area = 14ft × 20ft = 280 square feet

Diameter of circular light fixture = 3 feet

Radius of circular light fixture = 1.5 feet

So, Area of circular light fixture = πr^{2}

= 3.14(1.5)^{2}

= 3.14 × 2.25

= 7.065 or 7 square feet

So, area for painting = Total ceiling area - Area of circular light fixture

= 280 - 7

= 273 square feet

OLEGan [10]

Answer:

Step-by-step explanation:

The formula for determining simple interest is expressed as

I = PRT/100

Where

I represents interest paid on the amount deposited.

P represents the principal or amount deposited.

R represents interest rate

T represents the duration in years.

From the information given,

P = 80

R = 2.1%

T = 10 years

I = (80 × 2.1 × 10)/100 = $16.8

The total amount that she would have after 10 years is

80 + 16.8 = $96.8

She wouldn't have enough money to buy a TV for $1,000
