Answer:

Step-by-step explanation:

a^2 + b^2 = c^2

11^2 + 7 ^2 = c^2

121 + 49 = 170

√170 = 13.04

Answer:

c = 13.0

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

c² = 11² + 7² = 121 + 49 = 170 ( take the square root of both sides )

c = [tex]\sqrt{170}[/tex] ≈ 13.0 ( to the nearest tenth )

Solve the following system of equations.
- 7x-9y= 10
3x – 2y = 25

Answers

Answer: first one x= -9/7y+-10/7, second x=2/3y+25/3

1. Step-by-step explanation:

add 9y to both sides -7x-9y+9y=10+9y

divide both sides by -7. -7x/-7=9y+10/-7

2. Add 2y to both sides. 3x-2y+2y=25+2y

divide both sides by 3. 3x/3=2y=25/3

What is unit conversion?

To convert any unit into another is called a unit conversion.

In order to convert units, we need to care about their dimensions their dimension should not be changed.

For example conversion of a kilometer to a meter is to multiply by 1000 but meter and kilometer both unit is for distance only.

Another example could be kilo gram to gram.

Given the length of the pencil

Lenght = 13.5 cm

Also,

1cm = 0.39 inches

So,

Lenght = 13.5 × 0.39 = 5.265 inches.

Now,

Since 12 inches = 1 feet ⇒ 1 inch  = 1/12 feet

So,

Length = 5.265/12 = 0.43875 feet.

Hence "The value of the length of the given pencil will be 0.43875 feet.".

Mount Mauna Kea is the tallest mountain when measured from its base. It rises from 5854m below sea level to 4349m above sea level. How tall is Mount Mauna Kea? Use numbers and words to explain your thinking. *

Answers

Answer:

10,203 meters tall

Step-by-step explanation:

Sea Level is given a value of 0 and is measured as the starting point. Anything below sea level would be a negative value. Therefore, to calculate the total height of Mount Mauna Kea we would need to add the height below sea level with the height above sea level as both positive values.

5854m + 4349m = 10,203m

Finally, we can see that Mount Mauna Kea is 10,203 meters tall.

CAN ANYBODY HELP ME WITH THIS JUST WITH 7 TO 12 PLEASE IT IS FOR AN GRADE!!

Answers

Answer: I think there is a mistake for the first one because I did the math and I got 200 added but then there are more answers to this one, I added all the others by 200 and got the next number but then when I got to 6,300 I can't get the 6,700. I get something else, I add 6,000 with 200, and then I get 6,200 instead of getting 6,300. Then I added that 6,200 and 200 and got 6,400. I am confused with the second one, can you please help me understand that one. The third one is also confusing, The one is 12 nuggets eaten per minute.

It takes five people four hours to paint a fence.

How long would it take ten people to paint the same fence at the same rate?

Remember to include units in your answer.

Answers

Answer:

2 hours

Step-by-step explanation:

First, we notice that the time taken to paint a fence is inversely proportional to the number people used because as the number of people increase, the time taken to paint the fence decreases.

5 people can paint a fence in 4 hours.

1 person can paint a fence in = 5 x 4

                                                = 20 hours

10 people can paint the fence in = 20/10

                                                      = 2 hours
