A board that measures 3/4 feet long is cut into 6 equal pieces. What is the length of each piece?
shusha [124]

Answer:

See below:

Step-by-step explanation:

So we know that there is a \frac{3}{4} feet long board and that it is split into 6 pieces.

With that information, we can split it by doing the following:

1. \frac{3}{4} *\frac{1}{6}

We can do this because we have a board that is 0.75 feet long and we multiply it by one sixth because we want to divide a fraction and to do that we have to flip the fraction.

After doing that, we get our answer of \frac{3}{24}=\frac{1}{8}

This means that each piece is \frac{1}{8} feet long.

Cheers!

Using the law of sines, find the solutions for the missing inputs.
SashulF [63]

\frac{a}{ \sin(a) }  =  \frac{b}{ \sin(b)  }
\frac{12}{ \sin(38) }  =  \frac{b}{ \sin(85) }
\frac{12}{ \sin(38) }  =  \frac{a}{ \sin(57) }
180 - (85 + 38) = 57
\frac{12}{ \sin(38) }  =  \frac{b}{ \sin(85) }
\sin(85)   \times  \frac{12}{ \sin(38) }  = b
\sin(57)   \times  \frac{12}{ \sin(38) }  = a

How many 2-digit numbers are multiples of either 5 or 7?
Svet_ta [14]

Answer:

46

Step-by-step explanation:

he count of numbers from 1 to n that are divisible by k is integer part of (n/k).

So the numbers from 1 to 99 divisible by 3 is int(99/3) = 33

Those divisible by 5: int(99/5) = 19

From the sum of those two, subtract those divisible by 15 = int(99/15) = 6

That gives you 33+19-6 = 46.

Now subtract the 1 digit numbers: 3, 5, 6, 9, or four of them

46 - 4 = 42 is the answer.

Hello there.

Question: I<span>n a cookie jar containing 6 chocolate chip cookies, 8 sugar cookies, and 10 peanut butter cookies, what is the probability that a person who isn’t looking as they pull out one cookie, will get a chocolate chip cookie?

Answer: First you need to calculate the total of cookies in the jar.
6 + 10 + 8 = 24.
There are 6 chocolate chip cookies. 
Therefore the fraction is </span>\frac{6}{24}
You can simplify it after that if you wish to.

In short, Your answer is \frac{6}{24} .
In simplified form it would be \frac{1}{4}.

Hope This Helps You!
