Which set of side lenghts can be used to form a right triangle

Nookie1986 [14]

<h3>Solution:</h3>

Pythagoras theorem can ONLY be used in right triangles.
Usually, the longest side is the hypotenuse.

Option A:

6² = 5² + 4²
=> 36 = 25 + 16
=> 36 ≠ 41

The <u>side lengths</u> given are <u>not possible</u> for a right triangle.

Option B:

50² = 40² + 30²
=> 2500 = 1600 + 900
=> 2500 = 2500

The <u>side lengths</u> given are <u>possible</u> for a right triangle.

Option C:

30² = 20² + 10²
=> 900 = 400 + 100
=> 900 ≠ 500

The <u>side lengths</u> given are <u>not possible</u> for a right triangle.

Option D:

4² = 3² + 2²
=> 16 = 9 + 4
=> 13 ≠ 16

The <u>side lengths</u> given are <u>not possible</u> for a right triangle.

<h3>In conclusion...</h3>

Option B is correct.

alina1380 [7]

Answer:

110beats/minutes

Step-by-step explanation:

we know we have 11 beats every 6 seconds,

that implies that there are 110 beats every 60seconds

and 60secs is a minute

that means 110beats/mins

With food prices becoming a great issue in the world; wheat yields are even more important. Some of the highest yielding dry lan

Rzqust [24]

Answer:

Option E) 61.6

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 100 bushels per acre

Standard Deviation, σ = 30 bushels per acre

We assume that the distribution of yield is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P(X>x) = 0.90

We have to find the value of x such that the probability is 0.90

P(X > x)

$P( X > x) = P( z > \displaystyle\frac{x - 100}{30})=0.90$

$= 1 -P( z \leq \displaystyle\frac{x - 100}{30})=0.90$

$=P( z \leq \displaystyle\frac{x - 100}{30})=0.10$

Calculation the value from standard normal table, we have,

$P(z$

$\displaystyle\frac{x - 100}{30} = -1.282\\x = 61.55 \approx 61.6$

Hence, the yield of 61.6 bushels per acre or more would save the seed.

Solve the pattern: <br> 15, 17, 32, 49, 81 __ __ ← those are the blank spaces.

stiks02 [169]

Answer:

130 and 211

Step-by-step explanation:

15+17= 32

17+32=49

32+49=81

49+81=130

81+130=211

Pedro is building a playground in the shape of a right triangle. He wants to know the area of the playground to help him decide

Bumek [7]

Answer:

Dimensions of rectangle:

Length =6 yards

Width=3 1/3 yards

Area of right triangle = 10 yd^2

Step-by-step explanation:

The right triangle has base as 6 yards and height as 3 1/3 of yards.

When we match this triangle with another right triangle to make the rectangle is another right triangle with sides 6 yards and 3 1/3 yards.

I'll upload the file for work.
