The distance between Earth and its moons is 2.115 · 10⁵ km. Then the correct option is D.
Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
Saturn’s rings span up to about (7.5 · 10⁻¹) of the distance between the Earth and its moons. If Saturn’s rings span up to (2.82 · 10⁵ kilometers).
The distance between Earth and its moons is calculated as,
⇒ 7.5 · 10⁻¹ x 2.82 · 10⁵
⇒ 0.75 x 2.82 · 10⁵
⇒ 2.115 · 10⁵ km
Thus, the correct option is D.

Answer:
They do form a proportion.
Step-by-step explanation:
To determine whether the two rates form a proportion, you can set up a proportion and check if the cross-products are equal.
The two rates you have are:
Rate 1: 7 inches in 9 hours
Rate 2: 42 inches in 54 hours
You can set up a proportion like this:
Rate 1 (inches per hour) / Rate 2 (inches per hour) = Time 1 (hours) / Time 2 (hours)
So, it becomes:
(7 inches / 9 hours) / (42 inches / 54 hours)
Now, let's calculate these fractions:
Rate 1 (inches pr hour) = (7 inches / 9 hours) ≈ 0.7778 inches per hour (rounded to 4 decimal places)
Rate 2 (inches per hour) = (42 inches / 54 hours) ≈ 0.7778 inches per hour (rounded to 4 decimal places)
Now, compare the two rates (rounded to 4 decimal places):
Rate 1 ≈ 0.7778 inches per hour
Rate 2 ≈ 0.7778 inches per hour
Since both rates are approximately equal to 0.7778 inches per hour, they do form a proportion. When two rates are in proportion, their ratios are equal, which is the case here.
Answer:
$150 = $7.50/hour × t
Step-by-step explanation:
To determine how long it will take Jimmy to earn $150 at a rate of $7.50 per hour, you can set up an equation.
Let "t" represent the number of hours it will take Jimmy to earn $150.
The equation for this situation is:
Earnings = Rate × Time
In this case,
Earnings is $150, Rate is $7.50 per hour, and Time is "t" hours.
So, the equation becomes:
$150 = $7.50/hour × t
Now, you need to solve for "t." To do that, you can divide both sides of the equation by $7.50/hour to isolate "t":
t = $150 / ($7.50/hour)
t = 20 hours
So, it will take Jimmy 20 hours to earn $150 at a rate of $7.50 per hour.
Answer:
7.50x = 150
Step-by-step explanation:
7.50x = 150
x = 150/7.50
x = 20 hours
B. 2x = 20
C. 2(x - 5) = 15
D. 2x - 20 = 0
E. 4x10 30
F. 15 = 5-2x
