A farmer had 22.75 bushels of corn. He sold 12 2/5 bushels at the market. His three friends bought the remaining bushels of corn. If each person bought the same amount, how many bushels did each friend purchase?

Answers

Answer:

Each friend bought 3.45 bushels of corn.

Step-by-step explanation:

12 2/5 as a decimal is 12.40. You do 22.75 minus 12.40, which gives you 10.35. Next you do 10.35 divided by 3, which gives you your final answer of 3.45.

A coach is ordering shirts for a team.



• The coach pays a one-time fee of $24.

• The coach also pays $8 for each shirt ordered.



Which function can be used to find c, the total amount the coach pays in dollars when k shirts are ordered?

Answers

Answer:

C=8k+24

Step-by-step explanation:

Answer:

24+8k=c

Step-by-step explanation:

Because he paid $24 but then he paid $8 per shirt but we don't know how many shirts he bought so that is where c comes in. K is the variable that gives us the full amount he paid for the one-time fee and the shirts all together.

if you reflect any shape across the x-axis and then rotate it 90 degrees clockwise about the origin, do you get the same results as if you reflect it across the y-axis and then rotate it 90 degress counterclockwise about the origin? what does this mean?

Answers

Yes, a shape can be reflected across the x-axis and then rotated 90 degrees in a clockwise direction around the origin to achieve the same results as a shape reflected across the y-axis and rotated in a counterclockwise direction. This implies that these two transformational sequences are similar.

What is reflection in Mathematics?

A reflection is referred to as a flip in geometry. A reflection is the shape's mirror image. A line, called the line of reflection, will allow an image to reflect through it. Every point in a figure is said to reflect the other figure when they are all equally spaced apart from one another.
