Answer: There are several important information's that are given in the question. First thing to do is note down those information's so that every information is specifically in hand while getting to the required answer.

Mass of the softball = 0.5 kg

Force at which the softball hits the glove of the catcher = 25 newton

Let us assume the acceleration = x

We already know that

Force = Mass * Acceleration

25 = 0.5x

x = 25/0.5

= 250/5

= 50 m/s^2

So the acceleration of the softball is 50 m/s^2

Mass of the softball = 0.5 kg

Force at which the softball hits the glove of the catcher = 25 newton

Let us assume the acceleration = x

We already know that

Force = Mass * Acceleration

25 = 0.5x

x = 25/0.5

= 250/5

= 50 m/s^2

So the acceleration of the softball is 50 m/s^2

Answer:

Answer:

50 m/s^2

Step-by-step explanation:

25 x 2 = 50 m/s^2

An equilateral triangle is also a(n) _____ triangle. obtuse right isosceles scalene

The answer is probably isosceles, because if the angles and congruent, the sides are congruent as well.

Mrs. Conley asks her class what kind of party they want to have to celebrate their excellent behavior. Out of all the students in the class, 5 want an ice cream party, 7 want a movie party, 10 want a costume party, and the rest are undecided. If 20, percent want an ice cream party, how many students are in the class?

The number of students in Mrs. Conley's class given the number of students that like ice cream and their percentage is 25.

How many students are in the class?Percentage can be described as a fraction of an amount that is usually expressed as a number out of hundred. The sign used to represent percentages is %.

Number of students in the class = students that like ice cream / percentage

5 / 20%

5 / 0.2 = 25

Answer:

So pretend "X" is our variable for the total number of students in the class. We know that 5 is 20% of X. We understand that 0.20x = 5. So 0.20x divided by 0.20 gives us the remaining variable, X. If we do that, we also need to divide the other side by 0.20, so 5 divided by 0.20 is 25. The so the answer is 25 students in Mrs. Conley's class.

HELP!!!!!!!!!!!!!!!!!!!!!!!!! A company produces accessories for smart phones and tablets. The profit on each smart phone case is $2 and the profit on each tablet case is $3. The company made a profit of $1,200 on the cases last month. The equation 2x + 3y = 1,200 represents the company's profit from cases last month, where x is the number of smart phone cases sold and y is the number of tablet cases sold.

2.Describe how you would graph this line using the slope-intercept method. Be sure to write in complete sentences.

2x + 3y = 1200

3y = -2x + 1200

y = -2/3x + 400......slope = -2/3....y int = (0,400)...x int = (600,0)

start at (0,400)...and since ur slope is -2/3, go down 2 spaces, and to the right 3 spaces...plot this point...then go down 2, and to the right 3...plot this point....keep doing this and u should cross the x axis at (600,0).

3y = -2x + 1200

y = -2/3x + 400......slope = -2/3....y int = (0,400)...x int = (600,0)

start at (0,400)...and since ur slope is -2/3, go down 2 spaces, and to the right 3 spaces...plot this point...then go down 2, and to the right 3...plot this point....keep doing this and u should cross the x axis at (600,0).
