Answer:

1\frac{5}{6}-\frac{4}{6}=1\frac{1}{6}

Step-by-step explanation:

1) We have a bigger bar 1\frac{1}{6} and 4 little bars of \frac{1}{6}

2) There is a subtraction. This is why 4 little bars of \frac{1}{6} are being taken away. Look at the arrow direction

3)1\frac{5}{6}-\frac{4}{6}=1\frac{1}{6}

Two parallelograms are similar. The base of the first is 12cm, and its height is 8 cm. Find the base of the second parallelogram
bearhunter [10]

Answer:

The base of the second parallelogram is 51cm.

Step-by-step explanation:

If the parallelograms are similar, it means by applying the same scale factor to all the sides in one gives you the other. The question tells us the height of the first shape is 8cm and the height of the second shape is 34cm. That means the scale factor is:

\frac{34}{8}=4.25

Apply this same scale factor to the base of the first shape to find the base of the second:

12 \times 4.25=51

Could someone please help me? Thank you and explain the work because I don’t get this
lesya [120]

Answer:

5.59 times per second.

Step-by-step explanation:

Direct variation is in the form:

y=kx

Where <em>k</em> is the constant of variation.

Inverse variation is in the form:

\displaystyle y=\frac{k}{x}

In the given problem, the frequency of a vibrating guitar string varies inversely  as its length. In other words, using <em>f</em> for frequency and <em>l</em> for length:

\displaystyle f=\frac{k}{\ell}

We can solve for the constant of variation. We know that the frequency <em>f</em> is 4.3 when the length is 0.65 meters long. Thus:

\displaystyle 4.3=\frac{k}{0.65}

Solve for <em>k: </em>

<em />k=4.3(0.65)=2.795<em />

<em />

So, our equation becomes:

\displaystyle f=\frac{2.795}{\ell}

Then when the length is 0.5 meters, the frequency will be:

\displaystyle f=\frac{2.795}{.5}=5.59\text{ times per second.}
