9514 1404 393

Answer:

  1333.3 N

Step-by-step explanation:

The centripetal acceleration is given by ...

  a = v^2/r

  a = (100m/s)^2/(3 m) = (10^4)/3 m/s^2

Then the force on the ball is ...

  F = Ma = (0.4 kg)(10^4)/3 kg·m/s^2 ≈ 1333.3 N

A factory makes 1200 shirts every 6 hours.the factory makes shirts for 9 hours a workday. what is the fewest number of workdays
Dominik [7]
1. Divide the target number of shirts, 12,600 by the company's rate of making the shirts. That is,
                                 number of hours = 12,600 shirts/ (1200 shirts/6 hours)
                                                               = 63 hours
2. Determine the number of workdays for them to complete the shirts by dividing 63 hours by 9 hours/workday. This will give us an answer of 7 workdays.

If f = {(2,5), (3, 2) (4, 6), (5, 1), (2, 2)), then f is a function.
KiRa [710]

Answer:

false

Step-by-step explanation:

f is not a function because you can see that two of the points are (2,5) and (2,2). A function can only have one corresponding y-coordinate for every x-coordinate and since this is not the case here, f is not a function.

Vance bought 2 packages of large beads
VashaNatasha [74]

The no. of more buttons than beads that Vance bought is 1 (medium package)

<h3>What is an algebraic expression?</h3>

In mathematics, an expression that incorporates variables, constants, and algebraic operations is known as an algebraic expression (addition, subtraction, etc.).

<h3>How to solve algebraic expressions? </h3>

A General Rule for Equation Solving

B Remove parenthesis from either side of the equation and combine similar phrases to make it simpler.

C To separate the variable term on one side of the equation, use addition or subtraction.

D To find the variable, use division or multiplication.

Given:- The no: of package of large beads is 2

            The no: of the package of medium beads is 1

            The no: of the package of large buttons is 2

            The no: of the package of medium buttons is 2

Hence large packages

2(buttons)-2(beads)=0

For medium packages

2(buttons)-1(beads)=0

therefore, the no of more buttons than beads is 1 medium package
