7n-22 is more than or equal to 64 what is n

1 answer:

8 0

7n-22 ≥ 64

1. Move constant to the right.

7n ≥ 64 + 22

2. Combine like terms.

7n ≥ 86

3. Divide 7n by 7 to get n alone.

n ≥ 86

4. Divide 86 by 7.

n ≥ 86 / 7 OR n ≥ 12.29

What's the surface area ratio & the volume ratio??<br><br> please help me ASAP!!

Ulleksa [173]

Answer:

Step-by-step explanation:

Volumes of two spheres A and B = 648 cm³ and 1029 cm³

Things to remember:

1). Scale factor of two objects = $\frac{r_1}{r_2}$ [ $r_1$ and $r_2$ are the radii of two circles]

2). Area scale factor = $\frac{(r_1)^2}{(r_2)^2}$

3). Volume scale factor = $\frac{(r_1)^3}{(r_2)^3}$

Volume scale factor Or Volume ratio = $\frac{V_A}{V_B}$

$\frac{(r_1)^3}{(r_2)^3}= \frac{648}{1029}$

$\frac{r_1}{r_2}=\sqrt[3]{\frac{648}{1029} }$

$\frac{r_1}{r_2}=\frac{6(\sqrt[3]{3})}{7(\sqrt[3]{3})}$

$\frac{r_1}{r_2}=\frac{6}{7}$

Therefore, scale factor = $\frac{r_1}{r_2}=\frac{6}{7}$

≈ 6 : 7

Area scale factor Or area ratio = $(\frac{r_1}{r_2})^2=(\frac{6}{7})^2$

= $\frac{36}{49}$

≈ 36 : 49

Volume scale factor or Volume ratio = $\frac{648}{1029}$

= $\frac{216}{343}$

≈ 216 : 343

What equation can I use to find the side of a cube whose area is 729?

Tom [10]

#1 There is no area of a cube. There is only a volume.
#2 The formula is $V = s^{3}$ where s is the side.

Substitute 729 in V since that is the volume.
$729 = s^{3}$

Take the cube root and you will get 9.

So the formula is $V = s^{3}$ and the side is 9.
