Bryce intended to swim directly across a stream that is 99 meters wide. But the current caused him to arrive at the opposite sho
Misha Larkins [42]

Answer:

101 meters

Step-by-step explanation:

The direct path across the stream and perpendicular to both sides of the stream is one leg of a right triangle. The 20 meter distance on the arriving side of the stream is another leg of the right triangle. The path he actually took is the hypotenuse of the right triangle.

leg 1 = 99 m

leg 2 = 20 m

hypotenuse = ?

We have a right triangle, and we know the lengths of the two legs. We need to find the length of the hypotenuse, so we can use the Pythagorean theorem.

a^2 + b^2 = c^2

99^2 + 20^2 = c^2

9801 + 400 = c^2

c^2 = 10201

c = sqrt(10201) = 101

Answer: 101 meters

A game costs $39.00. But the new special edition version is going to be $56.94. What is the increased percent?
astraxan [27]

Answer:

46%

Step-by-step explanation:

<u>Step 1:  Make an expression</u>

<u />39.00 * x = 56.94

39x = 56.94

<u>Step 2:  Divide both sides by 39</u>

<u />39x / 39 = 56.94 / 39

x = 1.46

<u>Step 3:  Find the percent</u>

<u />1.46 - 1 -> Gives us the increased percent

0.46 * 100

46%

Answer:  46%
