The required scale model will be 1:6.24 10^9

<h3>Finding scale factors</h3>

A scale factor is the ratio of the length of a side of one figure to the length of the corresponding side of the other figure.

Given the following parameters

Distance of sun to Jupiter = 7.8 * 10^8 km

If the distance of sun to Jupiter is 8m on his scale, hence the value of n is calculated as;

n = 8 * 7.8 *10^8

n = 62.4 * 1068

n = 6.24 10^9

Hence the required scale model will be 1:6.24 10^9

Students were surveyed about their wither break plans.Of the people that stated they were going skiing, 25% did not actually go.

Romashka [77]

Answer:

The number of students who actually went for the skiing is 0.75 times the total number of students .

Step-by-step explanation:

Given as :

Students were surveyed about their wither break plans

The percentage of students who did not go for skiing = 25 %

So, The percentage of students who did not go for skiing =100 % - 25 % = 75%

Let The total number of students = x

So, The number of students actually went for the skiing = 75% of the total number of students

I.e The number of students actually went for the skiing = $\frac{75}{100}$ × x

Or, The number of students actually went for the skiing = 0.75× x

∴ The number of students actually went for the skiing = 0.75 x

Hence The number of students who actually went for the skiing is 0.75 times the total number of students . Answer

Which expressions are equivalent to 3(2x + 8) - 4x? Select ALL that apply.

Tcecarenko [31]

$3(2x + 8) - 4x \\ = 6x + 24 - 4x \\ = 2x + 24$
Let's see A
$8x + 24 - 6x \\ = 2x + 24$
Let's see B
$2x - 40 + 4 \\ = 2x - 36$
Let's see C
$2x + 20 + 4 \\ = 2x + 24$
Let's see D
$12x + 24 - 10x \\ = 2x + 24$
E. 2x + 24

So the answers are A, C, D and E.

Hope this helps.
