Hi there!
So you're looking at an equilateral triangle, which is a big word that basically means all three sides are equal and all three angles are 60°.
Knowing that, the mesure of one side is 7, so necessarily the side "x" is also equal to 7.
So the value of x is : 7
And since all angles are of 60°, necessarily the angle "y" has an angle of 60°.
So the value of y° is : 60°
There you go! I really hope this helped, if there's anything just let me know! :)
Answer:
Initially, you have 2573 pieces.
You use 5 pieces each minute.
Right when you start, you have 2573 pieces.
One minute after that, you have 2573 - 5 pieces.
Another minute after, you have 2573 - 2*5 pieces.
Another minute after, you have 2573 - 3*5 pieces.
And so on.
You can see the pattern here, and with this, we can find the linear equation that represents the number of pieces that you have as a function of time.
Then, if the variable t represents the number of minutes that passed since you started, we can write the equation:
f(t) = 2573 - 5*t
That represents the number of pieces that you have after t minutes.
Answer:
w = 13
Step-by-step explanation:
Using the method of cross- multiplying
•
=
⇒ ad = bc, thus
42(w + 11) = 28(w + 23) ← distribute parenthesis on both sides
42w + 462 = 28w + 644 ( subtract 28w from both sides )
14w + 462 = 644 ( subtract 462 from both sides )
14w = 182 ( divide both sides by 14 )
w = 13
Well 500 mm = 50 cm so if you add both segments together you will get a 50+30=80cm segment
