Can someone please help and explain how to use the Pythagorean Theorem to prove a triangle is a right triangle.

Answers

Answer 1

Hi there!

For the Pythagorean Theorem, basically you just need to apply this formula: a^2 + b^2 = c^2

And then find the root of the hypotenuse.

For example,

15^2 + 8^2 = the hypotenuse^2

Which equals, 225 + 64 = 289

Square root of 289 = 17

Please mark me brainliest if this helps!

Have a wonderful day!

Answers

Answer: here’s your answer

Step-by-step explanation:

pages are 60

sheet 15

on one sheet we get no of

pages=60/15=4

on one sheet we get 4 pages

they are stuck each other

so

let we consider

on1st sheet page no 1=60

2=59

so 7pageno. missing with also 8

(because attaching each other)

7=60-7

8=60-8

answer is 7,8,52,53pages are 60

Given:

In triangle KLM, KL = 123 cm and measure of angle K is 35 degrees.

To find:

The length of the side KM to the nearest tenth of a centimeter.

Solution:

In a right angle triangle,

[tex]\cos \theta =\dfrac{Base}{Hypotenuse}[/tex]

In the given right triangle KLM,

[tex]\cos K=\dfrac{KM}{KL}[/tex]

[tex]\cos (35^\circ)=\dfrac{KM}{123}[/tex]

[tex]0.819152=\dfrac{KM}{123}[/tex]

Multiply both sides by 123.

[tex]0.819152\times 123=KM[/tex]

[tex]100.755696=KM[/tex]

[tex]KM\approx 100.8[/tex]

The measure of side KM is 100.8 cm.

Therefore, the correct option is (2).

What is the volume of a sphere with a surface area of 25pi / (d ^ 2)

Answers

Answer:

B. [tex] \frac{125}{6}* \pi [/tex] yd³

Step-by-step explanation:

Given:

Surface area of a sphere = 25π yd²

Required:

Volume

Solution:

Let's find the radius (r) first.

S.A of sphere = 4πr²

Substitute

25π = 4πr²

Divide both sides by 4π

25π/4π = r²

25/4 = r²

Take the square root of both sides

√25/√4 = r

5/2 = r

r = 5/2 yd

Find the Volume of the sphere

V = ⁴/3*πr³

V = ⁴/3*π*(⁵/2)³

V = ⁴/3*π*125/8

V = ⅓*π*125/2

V = [tex] \frac{1*125}{3*2}* \pi [/tex]

V = [tex] \frac{125}{6}* \pi [/tex] yd³

Answers

Answer:

0.8214

Step-by-step explanation:

We have

F(x) = 1/b-a

With b = 7

And a = 0

Such that we have

1/7-0

= 1/7

Probability of x> 1.25

7-1.25

= 5.75

1/7 x 5.75

= 0.8214

Therefore the probability that a randomly selected passenger has a waiting time more than 1.25 minutes is = 0.8214.

The mean of a standard normal probability distribution _____. a. can be any value b. can be any value as long as it is positive c. is always equal to 1 d. None of these answers are correct.

Answers

Answer:

D

Step-by-step explanation:

The mean of a standard normal distribution is always = 0 with the standard deviation being equal to. Therefore a standard normal distribution is a normal distribution described with a mean of 0 and standard deviation of 1. Since a standard normal distribution is centered at the middle with equal distribution to both the left and right of the distribution. The centre point is 0, which is the mean and the standard deviation is 1 to either side of the distribution.

To solve a system of inequalities, you just need to graph each inequality and see wich points are in the overlap of the graphs.
True or false?

Answers

Answer: True

This is often how many math teachers and textbooks approach problems like this. The overlapped region is the region in which satisfies every inequality in the system. Be sure to note the boundary of each region whether you're dealing with a dashed line or a solid line. Dashed lines mean points on the boundary do not count as solution points, whereas solid boundaries allow those points as part of the solution set.

Side note: This is assuming you're dealing with 2 variable inequalities. If you only have one variable, you don't need to graph and instead could use algebra. Graphing doesn't hurt though.

f(h) = 11 + 1.2h

f(9) = 21.8 cm

Step-by-step explanation:

let 'h' = height

f(h) = 11 + 1.2h

height after 9 days:

f(9) = 11 + 1.2(9)

Answers

Answer:

0.057168

Step-by-step explanation:

Given :

Mean = 1510

Standard deviation = 57

P(X > 1600)

To obtain the Zscore we use

(x - mean) / σ

P(Z > 1600) = P(Z > (x - mean) / σ)

P(Z > (x - mean) / σ) = P(Z > (1600 - 1510) / 57)

P(Z > 1.579) = 0.057168 (Z probability calculator)

Answers

Answer:

x = 9

Step-by-step explanation:

m<K = 71°

arc JL = 16x - 2

m<k = ½(arc JL) => inscribed angles theorem

Substitute

71 = ½(16x - 2)

Multiply both sides by 2

71*2 = 16x - 2

142 = 16x - 2

Add 2 to both sides

142 + 2 = 16x - 2 + 2

144 = 16x

Divide both sides by 16

144/16 = 16x/16
