According to the information given in the exercise:

• 1 meter of lightning cable weight 85 grams.

,

• An empty spool weighs 260 grams.

,

• Ted weighs the partly used spool shown in the picture and its total weight is 1540 grams.

Then, knowing this, let be "x" the number of meters of cable left on the spool.

You can set up the following using the information given in the exercise:

Total\text{ }weight=Empty\text{ }spool+85(Meters\text{ }of\text{ }cable)

Knowing that:

\begin{gathered} Total\text{ }weight=1540 \\ Empty\text{ }spool=260 \end{gathered}

You can set up that:

1540=260+85x

Therefore, solving for "x", you get:

\begin{gathered} 1540-260=85x \\  \\ \frac{1540-260}{85}=x \end{gathered}x\approx15.059

Hence, you can conclude that the answer is: Second option.

IN NEED OF ANSWER :( A flower bed is in the shape of a triangle with one side twice the length of the shortest​ side, and the th
vichka [17]

Answer:

a = 33ft

b= 66ft

c = 48 ft

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

  • a (shortest side)= a
  • b (second side)=2a (twice the length of the shortest side)
  • c (third side)= a+15 ( 15 feet more than the length of the shortest side)

Since:  

Perimeter = a+b+c

Replacing with the values given:

147 = a+2a+(a+15)

147 = a+2a+a+15

147-15 = a+2a+a

132 = 4a

132/4 = a

33 ft= a  

Substituting a =33 in the other expressions:

b=2a = 2(33) = 66 ft

c= a+15 = 33+15 = 48 ft

Prove that tan60+tan70-tan50+tan10=2sqrt3?
LiRa [457]
{tan(60) + tan(10)}/{1 - tan(60)*tan(10)} - {tan(60) - tan(10)}/{1 + tan(10)*tan(60)} 

<span>ii) Taking LCM & simplifying with applying tan(60) = √3, the above simplifies to: </span>

<span>= 8*tan(10)/{1 - 3*tan²(10)} </span>

<span>iii) So tan(70) - tan(50) + tan(10) = 8*tan(10)/{1 - 3*tan²(10)} + tan(10) </span>
