Answer:

We know that the Pythagorean Theorem is a² + b² = c².  First lets start with 6, 8, and 10. There is a simple way to know that these are Pythagorean triples. They make up what is called a 3-4-5 triangle. 3 x 2 is 6, 4 x 2 is 8, and 5 x 2 is 10. Next 5, 12, and 13 are Pythagorean triplets because 5² + 12² = 13². Because both of these form right triangles, we know that they are Pythagorean triplets.

Hope this helps :-)

Ik I sent it again but here :)

Step-by-step explanation:

This units are used in measuring.

Kilometre=to measure the length

kilogram=to measure the mass

      similarities                                                                   differences

they measure 1000 times a value             one is for mass, one is for length

well that's it really

The answer is B

Step-by-step explanation:

Answer: In one night, 18 armadillos could eat 300 pounds of insects.

Step-by-step explanation: Knowing that 18 divided by 3 is equal to 6, you have to multiply the pounds of insects eaten by 3 armadillos by 6.

Unit price = total money / total weight:

2.50/2 = 1.25

Unit rate is 1.25 per 1 pound

The correct answer would be C.

Answer:

First, we divide each side by -3. Since the number that we are dividing by is negative we have to flip our inequality symbol.

Answer: so it goes -12-->4-->-5--->-7--->-1-->-9-->-6-->6-->45--->-36 And then your there! make sure you look at which numbers are positive and negative in my answer. your welcome :)

Step-by-step explanation:

Note that:

If you multiply 2 negative numbers, your answer will be positive.

If you multiply 1 negative & 1 positive number, your answer will be negative.

If you multiply 2 positive numbers, your answer will be positive.

Start:

-4 x 3 = -12

-2 x -2 = 4

25/(-5) = -5

(-49)/7 = -7

-5 x (1/5) = -1

(-3)(-3)(-1) = (-3 * -3)(-1) = (9)(-1) = -9

(3/4) x -8 = (3 * -8)/4 = 3 * -2 = -6

-18/-3 = 6

-9 x - 5 = 45

12/(-1/3) = 12 * -3 = -36

Finish.

~

the code will be the sum of all your answers:

-12 + 4 - 5 - 7 - 1 - 9 - 6 + 6 + 45 - 36 = -21

-21 is your code.

Answer: Question 1 is C. Question 2 is D.

Step-by-step explanation:

Question 1: If a train travels 90 miles PER hour and it travels for 3 hours, we would have to multiply. 90 times 3 is 270.

Question 2: It tells us that he already traveled for 3 hours and the total he traveled is 114. 114 divided by 3 is 38.

Answer:

Therefor Jasmine should cut each strip by 38.5Cm

Step-by-step explanation:

*Im pretty sure you meant 44cm by 33 Cm

To find the equal value between both construction papers you need to add both Width Values together then devide by 2, this will give us our (Average value) to help Jasmine cut each strip Equally as shown below:

44 + 33Cm = 77cm/2 = 38.5

Therefor Jasmine should cut each strip by 38.5Cm

if Jasmine wants more strips Example (10) solve using 38.5/10 3.85cm per strip (width)

Answer:

34483.48 in³

Step-by-step explanation:

We know ,

Substitute ,

Answer:

34,483.48!

Step-by-step explanation:

The formula for calculating the volume of a cylinder is π · r^2 · h. We can replace the numbers, like this: 3.14 · (17)17· 38. 17 times 17 is 289, so 3.14 · 289 · 38. 289 times 38 is 10,982, so 3.14 · 10,982. 3.14 times 10,982 is 34,483.48, so the volume of the cylinder is 34,483.48.
