Work out the length of <br> x<br> .<br> Give your answer rounded to 3 significant figures.
oksano4ka [1.4K]

Answer:

10.8 =x

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2  where a and b are the legs and c is the hypotenuse

8.8 ^2 + 6.2 ^2 = x^2

77.44+38.44=x^2

115.88=x^2

Take the square root of each side

10.76475731=x

Round to 3 significant figures.

10.8 =x

Can you give me the answer to these to questions? Plz I'm having trouble.
Colt1911 [192]
Hey there! :) I only see two questions so I assume you need help with those two if I am not mistaken. So lets start out with number 9!

So, for number 9 we have 5/4- 5/8. Always when you don't have the same denominators( the bottom number) we must find common denominators. So since 4*2= 8 our common denominator is 8! So this is a piece of cake since 5/8 is already in eighths. So we multiply 5*2= 10 and 4*2 = 8 so 5/4 is 10/8. Then we do 10/8- 5/8= 5/8. We only subtract the numerator and the denominator stays the same.

On to number 10! We have 2/3- 2/7. So lets find a set of common denominator. We can do 21, since 3*7= 21 and 7*3= 21! So 2*7= 14 and 3* 7 =21. So for 2/3 we have 14/21. For the 2/7, we do the same thing as before 2*3= 6 and 7*3= 21. So, 2/7= 6/21. Then the last step! Subtract 14/21- 6/21= 8/21. Then we simplify if needed! We don't need to simplify because it can't go any lower.

I hope I helped and explained it well! :D

Triple the difference of z and 10​
makvit [3.9K]
<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ It can be written like this:

3(z - 10)

The expanded version would be 3z - 30

<h3><u>✽</u></h3>

➶ Hope This Helps You!

➶ Good Luck (:
