A.24 mi./hr.

B.28 mi./hr.

C.30 mi./hr.

D.38 mi./hr.

Answers

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.

Referring to the figure, find the volume of the solid
shown. Use 3.14 for π. Round to the nearest whole number.

Answers

Answer:

34483.48 in³

Step-by-step explanation:

We know ,

Volume = πr²h

Substitute ,

V = 3.14 * 17 * 17 * 38 in.³V = 34483.48 in.³

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.

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.

How wide should Jazmin cut each strip?

Mark as brain list

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)

Answers

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.
