A net force acting on a 5.0 kg box produces an acceleration of 4.2 m/s2. What
acceleration will the same net force cause on a 2.8 kg box?

Answers

Answer 1

Answer:

14 N

Step-by-step explanation:

Let the mass of the box be m.

F = ma → F = 5 x 4.2 = 21 N

When mass = 2.8 kg, let the acceleration is a. For same force:

=> 21 = a x 2.8

=> 21/2.8 = a

=> 7.5 m/s² = a

Answer 2

Answer:

7.5M/s^2

Which numbers belong to the solution set of the inequality? x+6= 42​

Answers

Answer:

36

Step-by-step explanation:

Answer:

x=36 is your answer

Step-by-step explanation:

Simplifying

x + 6 = 42

Reorder the terms:

6 + x = 42

Solving

6 + x = 42

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6' to each side of the equation.

6 + -6 + x = 42 + -6

Combine like terms: 6 + -6 = 0

0 + x = 42 + -6

x = 42 + -6

Combine like terms: 42 + -6 = 36

x = 36

Simplifying

x = 36

hope it helps you ❣️

Answer:

10.25%

Step-by-step explanation:

Let the original number be represented with x.

Increase by 5% = 5% of x = 5/100 x X = 0.05x

So, the next number = x + 0.05x = 1.05x

Increase again by 5% = 5% of 1.05x = 5/100

x1.05x = 0.05 x 1.05x = 0.0525

So, the current number = 1.05x + 0.0525x =1.1025x

[tex] \frac{1.1025x - x}{x} = 0.1025 \times 100 = 10.25\%[/tex]

Complete question :

An ice cream stand uses the expression 2 + 0.5x2 to determine the cost (in dollars) of an ice cream cone that has x scoops of ice cream. How much does an ice cream cone with 5 scoops cost?

Answer:

$14.5

Step-by-step explanation:

Give the expression for the cost of ice cream cone with x scoops of ice cream :

Cost = 2 + 0.5x²

Cost of ice cream cone with 5 scoops of ice cream.

x = 5

Cost = 2 + 0.5(5²)

Cost = 2 + 0.5(25)

Cost = 2 + 12.5

Cost = 14.5

Hence, the cost of ice cream is $14.5
