The gravitational force that Earth exerts on an object is inversely proportional to the square of the distance between the center of the Earth and the object. When Bill is on the surface of Earth, 4,000 miles from the center, the gravitational force is 600 Newtons. What is the gravitational force (in Newtons) that the Earth exerts on him when he's standing on the moon, 240,000 miles from the center of the earth? Express your answer as a fraction
1/6 is the gravitational force (in Newtons) that the Earth exerts on him when he's standing on the moon.
What is gravitational force?The gravitational force is a force that attracts any two gadgets with mass. We name the gravitational force attractive as it always tries to pull masses together, it in no way pushes them apart. In fact, every item, consisting of you, is pulling on every different item in the entire universe.

Which equation correctly applies the distributive property?
A.(0.5⋅0.5)+(0.5⋅0.3)+(0.5⋅0.2)=0.5⋅(0.5+0.3+0.2)
B.−2.5⋅(4⋅1.045)=(−2.5⋅4)⋅1.045
C.−1.2⋅0.57⋅0.5=−1.2⋅0.5⋅0.57
D.50+1.015=(50⋅1)+(50⋅0.01)+(50⋅0.005)
Answer: Option 'A' is correct.
Step-by-step explanation:
Since we have given that
Distributive property which is expressed as
[tex]a\times (b+c)\\\\=a\times b+a\times c[/tex]
Similarly, in option 'A', we have
(0.5⋅0.5)+(0.5⋅0.3)+(0.5⋅0.2)=0.5⋅(0.5+0.3+0.2)
Here, a = 0.5,
b= 0.5
c = 0.3
d = 0.2
So, it can be expressed as
[tex]a\times (b+c+d)=a\times b+a\times c+a\times d[/tex]
Hence, Option 'A' is correct.

Which algebraic expression is equivalent to the expression below?
30 students 2/5 play an instrument and 5/6 play a sport. How many students play an instrument and how many play sport..?
Final answer:
There are 30 students in total, 12 of whom play an instrument, and 25 of whom play a sport.
Explanation:
The question asks about the number of students who play an instrument and the number who play a sport. There are 30 students in total.
To find the number of students who play an instrument, we multiply 30 by ⅓ (2/5), since 2/5 of the students play an instrument. To find the number of students who play a sport, we multiply 30 by ⅕ (5/6), since 5/6 of the students play a sport.
For the instrument calculation: 30 × 2/5 = 12, so 12 students play an instrument.
For the sport calculation: 30 × 5/6 = 25, so 25 students play a sport.

Maria made a scale drawing of an elephant. The scale is 1 inch to 13 feet. What is the scrutiny length of the elephant? In the pic the elephant is 1.5 inches long.
Scale: 1 inch = 13 feet. 1.5 inches on the drawing. Actual length: 1.5 * 13 = 19.5 feet. Elephant length.
To find the actual length of the elephant, you need to use the scale provided by Maria's drawing. The scale states that 1 inch on the drawing represents 13 feet in reality. Since the elephant in the drawing is 1.5 inches long, we can calculate the actual length using the scale.
1. First, determine how many feet one inch on the drawing represents:
[tex]\( 1 \text{ inch on drawing} = 13 \text{ feet in reality} \)[/tex]
2. Multiply the number of inches in the drawing by the conversion factor to find the actual length:
[tex]\( 1.5 \text{ inches on drawing} \times 13 \text{ feet/inch} = 19.5 \text{ feet in reality} \)[/tex]
So, the actual length of the elephant is 19.5 feet.

Professor Bartlett teaches a class of 12 students. She has a visually challenged student, Louise, who must sit in the front row next to her tutor, who is also a member of the class. Assume that the front row has seven chairs, and the tutor must be seated to the right of Louise. How many different ways can Professor Bartlett assign students to sit in the first row
Final answer:
Professor Bartlett can arrange the students in 1,440 different ways in the first row, considering Louise must sit next to her tutor on the right.
Explanation:
Professor Bartlett teaches a class of 12 students and needs to seat them in the front row which consists of 7 chairs. Specifically, Louise, who is visually challenged, must sit next to her tutor on the right side. To determine the number of different ways the students can be seated in the first row, we first consider the places of Louise and her tutor. Since Louise's tutor must be seated to her right, they can be viewed as a single entity with two internal arrangements: Louise on the left and the tutor on the right. Therefore, there are now effectively 6 entities to arrange (Louise and her tutor considered as one, plus the 5 other students) in 6 chairs in the front row.
The number of ways to arrange 6 entities in 6 spots is calculated by 6 factorial (6!), which equals 720. However, since Louise and her tutor can switch places within their designated spot, we must multiply this number by the 2 internal arrangements possible, resulting in 720 * 2 = 1,440 different seating arrangements for the first row.

maggie has only dimes and quarters in her purse. she has 27 coins with a total value of 4.05. how many dimes does maggie have in her purse
By solving a system of equations, we will see that Maggie has 18 dimes and 9 quarters.
How to write the system of equations?First, we define the variables that we will use:
D = number of dimes.Q = number of quarters.There are a total of 27 coins, so:
Q + D = 27.
The total value is 4.05, so:
Q*0.25 + D*0.10 = 4.05
Then our system of equations:
Q + D = 27
Q*0.25 + D*0.10 = 4.05
To solve this we need to isolate one of the variables in one of the equations, I will isolate Q in the first one.
Q = 27 - D
Now we can replace this on the other equation and solve it for D:
(27 - D)*0.25 + D*0.10 = 4.05
6.75 - D*0.25 + D*0.10 = 4.05
6.75 - D*0.15 = 4.05
6.75 - 4.05 = D*0.15
2.70 = D*0.15
2.70/0.15 = D = 18
So she has 18 dimes, and then the other 9 conis must be quarters.
