The distance from Earth to the moon is 2.4 × 105 miles. The distance from Earth to the sun is 9.3 × 107 miles. Complete the sent

Liono4ka [1.6K]

Answer:

$Distance = 9.276 * 10^7$ miles

Step-by-step explanation:

Given

$Earth\ to\ Moon = 2.4 * 10^5 miles$

$Earth\ to\ Sun = 9.3 * 10^7 miles$

Required

Difference in the distance of earth to sun to the distance of earth to moon

This can be solved using:

$Distance = Earth\ to\ Sun - Earth\ to\ Moon$

$Distance = 9.3 * 10^7 - 2.4 * 10^5$

Express 10⁷ as 10⁵ * 10²

$Distance = 9.3 * 10^5 * 10^2 - 2.4 * 10^5$

Factorize:

$Distance = 10^5(9.3 * 10^2 - 2.4)$

Solve the expression in the bracket

$Distance = 10^5(9.3 * 100 - 2.4)$

$Distance = 10^5(930 - 2.4)$

$Distance = 10^5(927.6)$

$Distance = 927.6 * 10^5$

Expand 927.6

$Distance = 9.276 * 10^2 * 10^5$

$Distance = 9.276 * 10^{2+5}$

$Distance = 9.276 * 10^7$

Simply the imaginary number square root -45

Paraphin [41]

Answer:

3i $\sqrt{5}$

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

and $\sqrt{-1}$ = i

Given

$\sqrt{-45}$

= $\sqrt{9(5)(-1)}$

= $\sqrt{9}$ × $\sqrt{5}$ × $\sqrt{-1}$

= 3 × $\sqrt{5}$ × i

= 3i $\sqrt{5}$

G=C+ x - y, for x<br> Help me solve this please

dedylja [7]

Answer:

x = g + y - C

Step-by-step explanation:

<u>Step 1: Add y to both sides</u>

g + y = C+ x - y + y

<em>g + y = C + x</em>

<em />

<u>Step 2: Subtract C from both sides</u>

g + y - C = C + x - C

<em>g + y - C = x</em>

<em />

Answer: x = g + y - C

NEED HELP ASAP FOR HOMEWORK!! IF RIGHT WILL MARK BRAINLIEST!!!

alexdok [17]

Answer:

It's the 3rd one using the formula $a^{-m} = \frac{1}{a^{m} }$

Once you follow that step you need to multiply the exponent of 3 and 6 with the exponent outside the parenthesis..... which is why it's the 3rd one.
