Blue's berry farm charges Percy a total of 24.75 for entrance and 2.5 kilograms of strawberries. The entrance fee 6$and the price for each kilogram of strawberries is constant

each kilogram of strawberries costs $ 7.5

Step-by-step explanation:

To know how much each kilogram costs, we first have to express the whole problem as an equation.

x will be the price of the ticket and y will be the price of 1 kg

1 X + 2.5 (y) = 24.75

As we know that the price of 1 ticket is $ 6 we replace that value and we can calculate the value of y.

x = 6

1(6) + 2.5(y) = 24.75

6 + 2.5y = 24.75

2.5y = 24.75 - 6

2.5y = 18.75

y = 18.75 / 2.5

y = 7.5

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
