Aaron has a 28.7 m length of rope. He uses 6.7 m of the rope
to make a rope ladder for a playground. He cuts the remaining
rope into 2 equal pieces to make tire swings. How long is each
tire swing rope?
Answer:
first step is to minus 28.7 - 6.7=22 (I did the minus because I want to get the remaining length of the rope )
step 2 : is to divide 22 by 2 (because the question said they should divide it into two pieces )
then the answer you get from the division of 22/2 which is 11 that would be the final answer
meaning each tire swing is 11m

Answer:
4/5
Step-by-step explanation:
Pick a point and call that A; the other point is B.
Take the Y part of B (the second number in the pair) and subtract the Y part of A.
3 - -1 = 4
Then, do the same thing but with the X (the first number in the pair)
so take the X part of B and subtract the X part of A.
5 - 0 = 5
and then put the 4 over the 5to get 4/5.
What is the interval of convergence for the power series the summation from n equals 1 to infinity of the product of negative n factorial and x to the nth power
Answer:
∞ and n = 1

what is the probability
Answer:
Probability in Maths:-
Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. Probability has been introduced in Maths to predict how likely events are to happen.
Formula for Probability:-
The probability formula is defined as the possibility of an event to happen is equal to the ratio of the number of favourable outcomes and the total number of outcomes.
Probability of event to happen P(E) = Number of favourable outcomes/Total Number of outcomes
Probability refers to a possibility that deals with the occurrence of random events also can be state as all the events occurring need to be 1.

Emily has 4 1/2 cups of chocolate chips. Her cookie recipe requires 3/4 cup of chocolate chips. How many batches of cookies can Emily make?
Answer:
There are 6 batches of chocolate chip cookies that can be made.
Step-by-step explanation:
First, turn 4 1/2 cups into an improper fraction with a denominator of 4 (which is 18/4). Then, do 18/4 divided by 3/4 (or 18/4 times 4/3 and both 4s cancel). The result is 18/3 or 6 because 3 times 6 equals 18.
