Please help i don’t know the middle one
Gnom [1K]

Answer:

Step-by-step explanation:

A new study suggests that waiting at least an hour after dinner before going to sleep reduces your risk of stroke by about two-thirds.

And for every 20 minutes more that you wait, stroke risk drops another 10%, says researcher Cristina-Maria Kastorini, MSc, a nutritionist at the University of Ioannina Medical School in Greece.

The study does not prove cause and effect -- only that there seems to be an association between waiting an hour or more between dinner and bedtime and reduced stroke risk.

Results of the 1,000-patient study were presented here at the European Society of Cardiology Congress 2011.

A ramp is built in the shape of a right triangleThe hypotenuse of the ramp is 17 ft and the length of one leg is 8 ft. What is t
rjkz [21]

Answer:

B

Step-by-step explanation:

We can easily solve this problem by using the Pythagorean Theorem.

The Pythagorean Theorem says:

One Leg ^ 2 + Another Leg ^ 2 = Hypotenuse ^ 2

<u>Note:</u> This theorem holds true for right triangles

This problem is in fact of a right triangle as said. So we use the theorem to find the other leg's length.

One Leg ^ 2 + Another Leg ^ 2 = Hypotenuse ^ 2

8^2 + Another Leg ^ 2 = 17^2

64 + Another Leg ^ 2 = 289

Another Leg ^ 2 = 289 - 64

Another Leg ^ 2 = 225

The other is the square root of 225, which is 15

The correct answer is B
