A brace for a shelf has the shape of a right triangle. Its hypotenuse is 10 inches long and the two legs are equal in length. Ho
vagabundo [1.1K]
This is a classic example of a 45-45-90 triangle: it's a right triangle (one angle of 90) & two other sides of the same length, which means two angles of the same length (and 45 is the only number that will work). With a 45-45-90 triangle, the lengths of the legs are easy to determine:
45-45-90
1-1-sqrt2
Where the hypotenuse corresponds to sqrt2.
Now, your hypotenuse is 10.
To figure out what each leg is, divide 10/sqrt2 (because sqrt2/sqrt2 = 1, which is a leg length in the explanation above).
Problem: you can't divide by radicals. So, we'll have to rationalize the denominator:
(10•sqrt2)/(sqrt2•sqrt2)
This can be rewritten:
10sqrt2/sqrt(2•2)
=10sqrt2/sqrt4
=10sqrt2/2
=5sqrt2 Hope this helps!!

What kind of triangle does it form?
Gwar [14]

Answer:

It forms a scalene triangle

Step-by-step explanation:

This is because scalene triangle does not have any of its sides equal.

\sqrt{111} is also 10.54.And looking at the measurements none of it are equal to each other so therefore it is a scalene triangle

Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage r
GREYUIT [131]

Answer:

  • Decay
  • Decrease rate is 8%

Step-by-step explanation:

<u>Given function:</u>

  • y = 490(0.92)^x

The base of the exponent is 0.92. This represents a decay as 0.92 is less than 1. It would be a growth function is the base was greater than 1.

<u>The rate of decrease is </u>

  • 0.92 times

<u>Percent decrease is </u>

  • (1 - 0.92)*100% = 8%

The city soccer club has thirteen new members and fifty-two returning members. If they break up into teams of eleven players, ho
Vedmedyk [2.9K]

Answer:

5

Step-by-step explanation:

The easiest way to do this is to add the new members to the old and then divide by 11. Ignore the remainder.

13 + 52 = 65

65 / 11 = 5 with 10 left over. Ignore the 10. That's not a complete team.

The answer is 5
