You had 23 dollars to spend on 4 avocados. They were very green. After buying them you had 11 dollars. How much did each avocado cost?
Answers
Answer:
$3
Step-by-step explanation:
Because you subtract $23-$11 to get the total you spent on avocados then you divide 12/4 because you bought 4 avocados
Answer:
3 dollars for each avocado.
Step-by-step explanation:
Since you had 23 dollars in the beginning and 11 dollars in the end, subtract to find out how much was used for the avacados.
23-11=12
Next, since you bought 4 avocados, you divide 12 by 4 to find out how much each cost.
12/4=3
Each avocado cost 3 dollars.
You can check by multiplying 3 by 4.
3x4=12
Then, add the 12 dollars spent to the 11 dollars left.
12+11=23 dollars

B. alternate interior angles theorem
C. alternate exterior angles theorem
D. corresponding angles postulate
E. linear pair postulate
Answers
Answer:
C. Alternate Exterior Angles Theorem
Step-by-step explanation:
I took the test
The corresponding angles postulate and the vertical angles theorem are proving ∠6 = ∠13. Therefore, options B and D are correct answer.
From the given figure, lines GN and FH are intersecting by the line segments KL and JM.
What are angles of parallel lines?Angles in parallel lines are angles that are created when two parallel lines are intersected by another line called a transversal.
From the given figure, we can see that
∠6 = ∠10 (Corresponding angles are congruent)
∠10 = ∠13 (Vertical angles are congruent)
Now, ∠6 = ∠10 = ∠13
The corresponding angles postulate and the vertical angles theorem are proving ∠6 = ∠13. Therefore, options B and D are correct answer.

Wow! There are 2 things going on here, so let's go step by step.
The first thing to notice is that the numbers are going negative, positive, negative, positive. Odd-numbered terms are negative while even-numbered terms are positive. Since 9 is odd number, we know the answer must be negative.
Secondly, the 1, 4, 9, 16 sequence is called the square numbers. They are 1 x 1, 2 x 2, 3 x 3, 4 x 4, etc. The 9th term will be 9 x 9 ( ignoring the negative).
Adding the first point with the second, we get (-81) { negative eighty-one }

how long will it take a ball to roll 10 meters along the floor at a velocity of 0.5 m/s
Please helppp
Answers
20 seconds.
Explanation:
The following data were obtained from the question:
Distance = 10 m
Speed = 0.5 m/s
Time =...?
The speed of an object is simply defined as the distance travelled by the object per unit time. Mathematically, it is expressed as:
Speed = Distance /time
With the above formula, we can obtain the time taken for the ball to travel a distance of 10 m as shown below:
Distance = 10 m
Speed = 0.5 m/s
Time =...?
Speed = Distance /time
0.5 = 10/time
Cross multiply
0.5 × time = 10
Divide both side by 0.5
Time = 10/0.5
Time = 20 secs.
Therefore, it will take 20 seconds for the ball to travel a distance of 10 m.
