Apark measures 85.5 square yards. a family rents 3/10 of that area to host a birthday party. how large is the area that the family rents?
0.30 square yards
8.55 square yards
10.00 square yards
25.65 square yards

To find the area the family rents, multiply the total area by the portion the family rents:

85.5 x 3/10

When multiplying with fractions, multiply the whole number by the numerator ( top number in the fraction) then divide that total by the denominator ( bottom number of a fraction)

85.5 x 3 = 256.5

256.5 / 10 = 25.65

The family rents 25.65 square yards.

25.65 square yards

Step-by-step explanation:

The area is 85.5 yd^2

He rents 3/10ths

Multiply the area  by the fractional part he rents

85.5 * 3/10

256.5/10

25.65 yd^2

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
