Answer:

6 hours.

Step-by-step explanation:

Let t represent the time taken by apprentice in hours to make a set of glasses when working alone.  

Part of work completed by apprentice in one hour would be \frac{1}{t}.

We have been given that a glassblower can produce a set of simple glasses in about 2 hours. So part of work completed by glassblower in one hour would be \frac{1}{2}.

While working together, the job takes about 1.5 hours. So part of work completed by both in one hour would be \frac{1}{1.5}.

Now we will equate sum of work competed by both in hour by work completed by both working together is one hour as:

\frac{1}{t}+\frac{1}{2}=\frac{1}{1.5}

\frac{1}{t}\cdot 3t+\frac{1}{2}\cdot 3t=\frac{1}{1.5}\cdot 3t

3+\frac{3}{2}\cdot t=\frac{3t}{1.5}

3+1.5\cdot t=2t

3+1.5t-1.5t=2t-1.5t

3=0.5t

\frac{3}{0.5}=\frac{0.5t}{0.5}

6=t

Therefore, it will take 6 hours for the apprentice to make a set of glasses when working alone.

Rafael received 5/6 of 180 volts how many votes did he receive
Kruka [31]

Answer:  The answer would be 6

Here is an example:

If you divided 64 by 5/8, then you would get a number larger than 64.

To get the answer, multiply 64 * 5/8. So find what 64*5 is then divide that number by 8. 64*5=320. 8 goes into 32 4 times, so it goes into 320 40 times. So your answer is 40.

Hope this helps,

What is the value of r to the nearest tenth?
Tatiana [17]

Answer:

Hence r=10.3 cms (rounded to tenth place)

Step-by-step explanation:

In Triangle KLN ,

KN = 5 Cms

LN = ½ of LM

As the Perpendicular dropped from the center to the chord bisects it.

LM = 18 cm

LN = 9 cm

Now we have to find r or KL

We apply Hypotenuse Formula in this

The formula is given as

c=\sqrt{a^2+b^2}

Where c = r

a=5

b=9

Putting them in the formula

r=\sqrt{5^2+9^2}

r=\sqrt{25+81}

r=\sqrt{106}

r=10.29
