2.) Find the length of the unknown side. Round your answer to the nearest tenth.

Juli2301 [7.4K]

Answer:

14.1

Step-by-step explanation:

Hey There!

This is a right triangle so we have to use the Pythagorean Theorem to solve for the missing side

given the hypotenuse and a leg we do

$hypotenuse^2-given.leg^2$

$15^2-5^2=?^2\\15^2=225\\5^2=25\\225-25=200\\\sqrt{200} =14.1421356$

then we just round to the nearest tenth and get that

?=14.1

Daniel and Audrey are reading the same book. At the beginning of the month, Daniel was on page 49 and Audrey was on page 22. Dan

Klio2033 [76]

Answer:

9 days

Step-by-step explanation:

First, write the equation for Daniel's situation:

D = 17t + 49

Then, write the equation for Audrey's situation:

A = 20t + 22

Then, set these equations equal to each other and solve for t to find when they will be on the same page:

17t + 49 = 20t + 22

Solve for t:

17t + 49 = 20t + 22

49 = 3t + 22

27 = 3t

9 = t

So, they will be on the same page 9 days into the month.

A mountain bike has a diameter of 26 inches. To the nearest foot how far does the tire travel when it makes 32 revolutions?

Tcecarenko [31]

Hello!

You have to find the circumference

You use the equation

$2 \pi r$

r is radius which is half the diameter

This gives us 81.68

Multiply this by 32

81.68 * 32 = 2613.76

This is 217.8133333 feet

The answer is 217.8133 feet

Hope this helps!
