Mixed Practice

Mathematics
1 answer:
Pavel [41]2 years ago
8 0

Answer:

9 units and 12 units to nearest hundredth.

Step-by-step explanation:

Let one leg be x units long  then the other = x+3 units.

By Pythagoras:

x^2 + (x+3)^2 = 15^2 = 225

2x^2 + 6x + 9 = 225

2x^2 + 6x - 216 =0

x^2 + 3x - 108 = 0

(x - 9)(x + 12) = 0

x = 9

So the other 2 legs are 9 and 12.

Where 5- no of cups of bread crumbs needed; 9= pounds of ground beef needed

Step-by-step explanation:

Anything that can be represented in the x/y form constitutes the fraction.

Robin rolled a die and then flipped a coin. What is the probability she rolled an even number and the coin landed on heads?
aleksandr82 [10.1K]

Answer:

1/4

Step-by-step explanation:

There are 3 even numbers of the 6 numbers on a die.

(1,2,3,4,5,6) are the possible numbers.  2,4,6 are even

P( even number ) = 3/6 = 1/2

P (heads) = 1/2

Since they are independent events, we can multiply the probabilities together

P (even, heads) = 1/2 * 1/2 = 1/4
