3 0

Answer:

I think it's One Solution

Step-by-step explanation:

-6|9v-7|=0

Divide 6 on both sides

-6|9v-7| /6=0/6

Simplify

|9v-7|=0

Add a absoulte rule

9v-7=0

v = 7/9

I hope it's right!

Rzqust [24]

Work:

Jared is between Anita and Steph

67 $\frac{3}{4}$ - 42 $\frac{1}{2}$

Turn $\frac{1}{2}$ into $\frac{2}{4}$

Now

67 $\frac{3}{4}$ - 42 $\frac{2}{4}$

Do 67 - 42 first to make it easier
67 - 42 = 25
Then do $\frac{3}{4}$ - $\frac{2}{4}$

$\frac{3}{4}$ - $\frac{2}{4}$ = $\frac{1}{4}$

Then add the two back together to get 25 $\frac{1}{4}$

Remember that Steph is above Jared though.

Answer:

Steph is 25 $\frac{1}{4}$ feet above Jared.

blondinia [14]

Answer:

r = √(3V/(πh))
r ≈ 1.78 cm

Step-by-step explanation:

Multiply by the inverse of the coefficient of r², then take the square root.

$V=\dfrac{1}{3}\pi r^2h\\\\V=\dfrac{\pi h}{3}r^2\\\\r^2=\dfrac{3V}{\pi h}\\\\\boxed{r=\sqrt{\dfrac{3V}{\pi h}}}$

For V=50, h=15, this is ...

${r=\sqrt{\dfrac{3(50)}{\pi(15)}}=\sqrt{\dfrac{10}{\pi}}\approx\boxed{1.78\quad\text{cm}}$

Naily [24]

Answer:

Step-by-step explanation:

As the CD line is parallel to x-axis hence the separation or length is measured on the x-axis i.e.

the length of CD = length of C - length of D = 7 - 4 = 3
