The force F of attraction between two bodies varies jointly as the weights of the two bodies and inversely as the square of the

distance d between them. Express this fact as a variation using c as a constant. Use M1 and M2 for the weights of the two bodies.

Since we are to express the given conditions as a joint variation, we employ the use of k as our constant proportionality which we will denote in this item as k. 
 From the sentence,
                            F = kM₁M₂/d²
as we can see those in the denominator as those that vary inversely to the given parameter.

ariana grande is coming to north gulfport middle school for a fundraising benefit concert!Nevaeh is selling tickets.This week,sh
ArbitrLikvidat [17]

Answer:

Adult = $7

Kids = $4

Step-by-step explanation:

Before we can find the price of the tickets, we first need to create expressions that can be used to explain the prices.

Let x = Price of kids tickets

Let y = Price of adults tickets

For this week the expression is:

3x + 9y = 75

For the last week the expression is:

8x + 5y = 67

Now to be able to find the value of x or y, we can use the Solving Linear Equations by Multiplying First Method.

3x + 9y = 75

8x + 5y = 67

Now we need to remove either the x or y by multiplying the whole expressions by a certain number.

8(3x + 9y = 75)

24x + 72y = 600

3(8x + 5y = 67)

24x + 15y = 201

Now that we have our equations and we can eliminate the x by subtracting both expressions.

24x + 72y = 600

<u>- 24x + 15y = 201</u>

         57y = 399

To find the value of y, we divide both sides by 57.

\dfrac{57y}{57}=\dfrac{399}{57}

y = 7

Now that we have the value for y, we simply substitute the value in any of our expressions.

3x + 9y = 75

3x + 9(7) = 75

3x + 63 = 75

3x = 75 - 63

3x = 12

Now we divide both sides by 3 to find the value of x.

\dfrac{3x}{3}=\dfrac{12}{3}

x = 4

So the ticket prices are:

Adult = $7

Kids = $4

A bicycle store installs about 400 tires per day. Tires are installed Monday through Friday for 8 hours per day. The owner of th
dalvyx [7]
Dividing the number of tires that should be installed per day which  is 400 by the number of working hours which is 8 will give us 50 tires per hour. Assuming that the same mistake will take toll on the workers such that they will have 1 tire mistakenly installed in an hour, they will have 8 erroneous tires in a day. Multiplying this by 5 to make the answer per week will give 40. Out of the 400 x 5  = 2000 tires. The answer would be 2000 - 40 which is equal to 1940. The assumption must be valid.
