Shreya beat her school’s 50 meter freestyle record by swimming 25% faster than the previous record of 48 seconds. what is the new school record that shreya set?

To find x % of y we multiply y by x/100

The original record of swimming was of 48 s.

Shreya clocked 25% faster than the previous record

So the new record is 25% faster than the previous record.

Now 25% of 48

= 0.25 × 48

= 12 s

This means the new record must have been clocked 12 s less than the old record.

So the new record shall be

=48-12

= 36 s

The new school record that Shreya set is of 36 seconds

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)

ƒ = 0.03b
