So you can set up proportion.

\dfrac{7.5\ \text m}{76^\circ} = \dfrac C{360^\circ}

Here, you need to solve for C.

You can do that by multiple both sides by 360 and then you should get 360^\circ\cdot\dfrac{7.5\ \text m}{76^\circ} = C \approx \boxed{35.526\ \text m}

Hope this helps.

guajiro [1.7K]

SOLUTION:

We are to find the rate of inflation in the given question;

The formula to be used is;

Inflation rate =

\frac{\text{CPI}_{present}-CPI_{previous}}{CPI_{previous}_{}}\text{ X 100}\begin{gathered} \frac{221-208}{208}\text{ X }\frac{100}{1} \\  \\ \frac{13}{208}X\frac{100}{1} \\  \\ 6.25\text{ \%} \\ 6.3\text{ \% (nearest tenth of a percentage)} \end{gathered}

CONCLUSION

The inflation rate of CPI that increased from 208 to 221 to the nearest tenth of a percentage is 6.3%.

Place the indicated product in the proper location on the grid.<br> (4ya - 6xb)(4ya + 6xb)
k0ka [10]

Product of (4ya - 6xb)(4ya + 6xb) is 16y^2a^2-36x^2b^2

Step-by-step explanation:

We need to find the product of (4ya - 6xb)(4ya + 6xb)

Finding product:

Multiplying both terms:

(4ya - 6xb)(4ya + 6xb)\\=4ya(4ya+6xb)-6xb(4ya+6xb)\\=16y^2a^2+24yaxb-24xbya-36x^2b^2\\=16y^2a^2-36x^2b^2

So, product of (4ya - 6xb)(4ya + 6xb) is 16y^2a^2-36x^2b^2
