Ad libitum [116K]3 years ago
6 0

Answer:

Perimeter is 100

Step-by-step explanation:

A^2 + B^2 = C^2

20^2 + 15^2 = C^2

200 + 225 = C^2

C^2 = 625

C=25

Perimeter is 100

To get this you would do the 25 X 4 = 100 yds

Hope this helps :)

Answer: The fraction of the gifts were for birthdays = \dfrac{33}{100}.

Step-by-step explanation:

Given: fraction of gifts for weddings = \dfrac{3}{10}

fraction of gifts for baby showers = \dfrac{37}{100}

Rest of the gifts = 1-\dfrac3{10}-\dfrac{37}{100}

Hence, the fraction of the gifts were for birthdays = \dfrac{33}{100}.
