Answer:

$7:\dfrac{1}{3}=21$ pieces

Step-by-step explanation:

Suppose you have a 7 feet long wood.

You need to find how many $\frac{1}{3}$ -foot pieces can be cut from this wood.

To find this number of pieces, you have to divide the whole length of the wood by the length of one piece:

$7:\dfrac{1}{3}=\dfrac{7}{1}\cdot \dfrac{3}{1}=21$

Anna cuts four identical circles from a square piece of black poster board as shown. What is the area of the left over poster bo

nydimaria [60]

Formula for a circle: A=Pi*r^2
Diameter:2ft
Radius:1ft
A=3.14*1^2
A=3.14
Multiply by 4
4 squares=12.56ft squared
Formula for a square: A=s^2
A=4^2
A= 16ft squared
To find leftover you need to subtract 12.56 ft from 16 ft to get 3.44 ft squared(A).

Solve question 3 for <br> 41 points

Sever21 [200]

Answer:

(2)

Step-by-step explanation:

Our logarithmic expression is: $ln(\frac{\sqrt{e} }{y^3} )$ .

Remember the logarithmic property that ln(a/b) = lna - lnb. So, we can write this as:

$ln(\frac{\sqrt{e} }{y^3} )=ln(\sqrt{e} )-ln(y^3)$

Also, we can write square roots as powers of one-half, so √e = $e^{1/2}$ . There's another log property that: $ln(a^b)=b*ln(a)$ . We can apply that here for both the √e and the y³:

$ln(\sqrt{e} )-ln(y^3)=\frac{1}{2} ln(e)-3ln(y)$

Finally, note that ln(e) is just 1, so we have:

$\frac{1}{2} ln(e)-3ln(y)=\frac{1}{2} -3ln(y)=\frac{1-6ln(y)}{2}$

The answer is thus (2).
