Answer:

$10a^2$

Step-by-step explanation:

$\sqrt[3]{1000a^6}\\$

$\mathrm{Apply\:radical\:rule\:}\sqrt[n]{ab}=\sqrt[n]{a}\sqrt[n]{b},\:\quad \mathrm{\:assuming\:}a\ge 0,\:b\ge 0$

$=\sqrt[3]{1000}\sqrt[3]{a^6}\\10\sqrt[3]{a^6}\\10\sqrt[3]{\left(a^2\right)^3}\\10a^2$

The average distance from the center of the earth to the center of the moon is 385,000 km. To the nearest mile, how many miles i

Tasya [4]

Answer:

239,228 miles.

Step-by-step explanation:

We have been given that the average distance from the center of the earth to the center of the moon is 385,000 km.

First of all, we will convert 385,000 km into miles by multiplying 385,000 by 0.621371 as 1 km equals 0.621371 miles.

$385,000\text{ km}\times \frac{\text{0.621371 Miles}}{\text{ km}}=385,000\times0.621371 \text{ Miles}=239,227.909\text{ miles}$

Round to nearest mile:

$239,227.909\text{ miles}\approx 239,228\text{ miles}$

Therefore, the center of the earth is 239,228 miles from center of the moon.

Could someone guide me through this one plz A system of two equations is shown below: Equation C: a = 4b + 5 Equation D: a = 6b

stira [4]

A = 4b +5
a = 6b - 2

So, that means
4b +5 = 6b - 2
because they all equal to value a.

Also, this way you can solve the system of equation because they only have one undefined variable.

So, the answer is 4b +5
