Answer: 15 feet
Step-by-step explanation:
First you start with 2ft and 6in and convert it all into into inches.
If you know that 1 ft=12in then you know that 2 feet is the same as saying
12+12=24. If you don't understand use this chart-
1 ft=12in
2ft= 24in
3ft= 36in
4ft =48in
5ft= 60in
6ft= 72in
see I am counting by 12's.
Now take 2ft and convert it into inches. That would be 24 in (look in the chart).
now take the 24in(2ft) and add it to the 6in. So 24+6 =30
So now you know that one piece of pipe is 30in long.
But in the text it states that Don has 6 pieces, so...
because it says that he has 6 pieces of pipe then you are going to take that and multiply that number(6) by how long each piece is. look up and it shows how long each pieces is. They are all each 30in long. Take 30 and multiply that by 6 because there are 6 pipes and you will get 120in.
But it says that they need an answer of feet and inches or just feet if it exactly a some sort of foot like 43feet or 2 feet.
So then we are going to convert 180 into feet by dividing 180 by 12 and you get 15. So the answer is 15.
I hope this helps. Have fun learning!!
Answer:
6(2 + √3)
Step-by-step explanation:
Given : Rectangle GHIJ inscribed in a circle. <em>GK⊥JH</em>, <em>GK</em> = 6 cm and <em>m∠GHJ</em>=15°.
To find: Radius<em>(KH)</em> =?
Sol: As given in figure 1, Since <em>GK⊥JH ∴ m∠GKH = 90° . Let GK = x cm.</em>
Now, In ΔGKH,
(∵<em> tan 15°</em> = 2 - √3)
On rationalizing the above expression,
Therefore, radius of the circle <em>(KH)</em> = 6 (2+√3)
This is how to find the value of <em>tan 15°</em>
<em>tan</em> 15° = <em>tan </em>(45° -30°)
Now using,
On rationalizing,
Taking 2 common from numerator,
<em>tan</em> 15° = 2 - √3
Answer:
"The sum of two rational numbers is rational."
By definition, a rational number can be expressed as a fraction with integer values in the numerator and denominator (denominator not zero). So, adding two rationals is the same as adding two such fractions, which will result in another fraction of this same form since integers are closed under addition and multiplication. Thus, adding two rational numbers produces another rational number.
Answer:
Step-by-step explanation:
We have been given a formula for the surface area of a container in shape of right prism. We are asked to solve for h for our given formula.
First of all, we will switch sides for our given equation as:
Now, we will subtract 2B from both sides of our equation.
Now, we will divide both sides of our equation by P.
Therefore, option A is the correct choice.
<em>PLS MARK BRAINLIST </em>
To find the value of X, simply know that for this parallelogram, the angles on each end that are diagonal with respect to each other are the same. And knowing that the angles in a parallelogram add up to equal 360 degrees. Simply make an algebraic expression equal to the value of 360 and then solve for x.
X + X + (X - 26) + (X - 26) = 360
2X + X - 26 + X - 26 = 360
4X - 52 = 360
4x = 412
X = 103.
The value for X, I believe would be 103 degrees. You can verify this by plugging in the value into both expressions, X and X-26 and see that if adding all the expressions together does it equal 360 degrees.
