A freshly-planted sapling is braced by 3 cables attached to a collar secured to the sapling 8 feet up the trunk. each cable is s

taked into the ground 3 feet from the sapling's trunk. if fastening a cable to the collar uses 8 inches of cable and fastening it to its stake also uses 8 inches of cable, about how much cable has been used

The slant length of each cable can be calculated using Pythagoras Theorem,
L= √ (8^2+3^2)
= √ (64+9)
= √ (73)
Total length of each cable
T = L + 8/12 + 8/12
= √ (73) + 4/3 
Total length of cables required
= 3T 
= 3 ( √ 73 + 4/3)
=( 3 √ 73 + 4 ) feet

Can yall tell me what B is? b-7/4=-2/3
Rashid [163]

Answer:

1 1/12

Step-by-step explanation:

b-7/4=-2/3

First, in an equation like this, you add 7/4 to each side which will look like this:

b-7/4=-2/3

 +7/4=+7/4

We add 7/4 to each side of the equation to balance the numbers.

b=+7/4-2/3 (because the minus symbol is in front, we put that)

Before adding we have to find the least common denominator known as LCD.

We find that by first looking at the denominators or the fractions which are 4,3

4,8,\12/,16,20,24.

3,6,9,\12/,15,18,21,24.

We can also find the LCD by multiplying 3 and 4. As you can see in the list, there are 12's in each list of numbers. We use that to change our fractions.

From the number 4 we find out how many times (x) we have to add 4 to get 12. We do 12/4 which is 3. And 12/3 which is 4.

7 x 3       2 x 4

-------   -   -------

4 x 3       3 x 4

which equals 21/12-8/12. Now that we have a common denominator, we can subtract.

21                  8                    13

---        -        ---        =         -----     =    1  \frac{1}{12}

12                 12                    12

I hope this helps, please let me know if I have any incorrections. :D

Leslie had to unpack P packages at work. After unpacking U of them, what formula should Leslie use to determine the percentage o
sdas [7]

We are given two unknown variables P and U packages.

We can see that Leslie has to unpack P packages at work

However, after she had unpacked U number, she stopped.

To first subtract U from P because we were told that U number had been unpacked from P packages which was supposed to be unpacked.

This can be represented mathematically as <em>P-U</em>

Next, we would have to find the percentage of packages <em>not yet unpacked </em>and this would be:

  • ((P-U)/P)*100

<h3>Unknown Variable</h3>

This refers to an undefined variable which has not yet been disclosed and <em>remain unknown</em> until a value is given to them.

For a certain triangle ABC, if a line intersects AC at D, intersects AB at E, and is parallel to CB, would the proportion AE | A
lions [1.4K]

The given proportion of triangle ABC as AE/AD = EB/DC is; Not Accurate

<h3>Understanding Basic proportionality theorem(Thale's Theorem)</h3>

This theorem states that If a line is drawn parallel to one side of a triangle, then it cuts other two sides proportionally.

Thus, In ΔABC, DE || BC

By Thales theorem, we can say that;

AD/DB = AE/EC

Rearranging we can arrive at;

AE/AD = EC/DB

When we simplify further by adding 1 to both sides, we will get;

AD/AB = AE/AC

Thus, the given proportion is not accurate
