Look below.

Step-by-step explanation:

[tex]11^2+9^2=x^{2} \\\\121+81=x^{2} \\202=x^{2} \\\sqrt{202}[/tex]

The measure of the side length (that is hypotenuse) of the right-angle triangle will be √202 units.

What is a Pythagoras theorem?

The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.

The Pythagoras theorem formula is given as

H² = P² + B²

Let the missing side of this right triangle be х.

Then the measure of the side length (that is hypotenuse) of the right-angle triangle will be

x² = 9² + 11²

x² = 81 + 121

x² = 202

 x = √202

Hope it helps

n plzz mark meh da brainliest

Answer: a=101 b=79 c=83 d=97

Step-by-step explanation:

A: angles on a straight line add up to 180° so you would take away 79° from 180° which is 101°.

B: angles on a parallel lines are always the same, you can see that 79 is at the same position as b.

C: opposite angles are always the same so it would still be 83°.

D: d is on other side as c and this would add up to 180° so as we already know that c is 83° you would have to take away 83° from 180° to get d.

Are the 2 lines:

y = 4x - 3 and y = (1/4)x +3

Parallel, Perpendicular, or Neither?
Please let me know an explanation would be great I hate my math teach but thank you!

Answers

Answer:

Step-by-step explanation:

Both equations are in slope-intercept form, so the coefficient of x is the slope of the line.

y = 4x-3

slope = 4

y = (¼)x + 3

slope = ¼

If the slope are the same, the lines are parallel. If the product of the slopes = -1, the lines are perpendicular.

4×¼ = 1

The lines are neither parallel nor perpendicular.

I’m pretty sure it’s perpendicular

What is the probability of rolling a 3 on a six-sided cube AND rolling a 6 on a six-sided cube?
ob

Answers

Answer:

The probability of not rolling a 5 AND not spinning a 5 is (5/6)*(4/5)=20/30

Step-by-step explanation:

These are independent events.

The probability of rolling a 5 is 1/6.

The probability of spinning a 5 is 1/5.

The probability of rolling a 5 or spinning a 5 is 1/5+1/6=11/30 but you have to subtract 1/30 because you can roll a 5 and spin a 5 at the same time. Therefore 11/30-1/30=10/30=1/3.

There are 30 outcomes. Roll first then spin to get the following outcomes:

11,12,13,14,15,21,22,23,24,25,31,32,33,34,35,41,42,43,44,45,51,52,53,54,55,61,62,63,64,65

You want to roll a 5 OR spin a 5. How many combinations have a 5 ? 10 combinations have a 5.

(you don't count 55 twice) There are 10 combinations with a 5 out of a possible 30 combinations.

Another way of looking at the problem is the following:What is the probability of NOT rolling a 5 AND NOT spinning a 5 ?

The probability of not rolling a 5 AND not spinning a 5 is (5/6)*(4/5)=20/30. Therefore the probability of rolling a 5 or spinning a 5 is 1-20/30=10/30.

Answer:

16.7%

Step-by-step explanation:

There are 6 sides and one three on the cube so rolling a three would be 1/6. To roll a 6 on a 6 sized dice would be the same there’s 6 sides and one 6 so it would be 1/6

Answers

Answer:

k = 24, y = 24x

Step-by-step explanation:

Given x and y are proportional then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition when y = 72, x = 3 , then

72 = 3k ( divide both sides by 3 )

k = 24

y = 24x ← equation of proportion
