D.
12.62 m/s²

Answers

Answer 1
Answer:

The greyhound's average acceleration will be;

⇒ Acceleration = 12.62 m/s²

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

A greyhound can go from a state of resting to running at 19.44 meters per second in 1.54 seconds.

Now,

Since, A greyhound can go from a state of resting to running at 19.44 meters per second in 1.54 seconds.

Hence, Initial velocity = 0

Final velocity = 19.44 meter per second

And, Time = 1.54 seconds

Since, Acceleration = Change in velocity / Time

Hence, We get;

⇒ Acceleration = Change in velocity / Time

⇒ Acceleration = (19.44 - 0) / 1.64

⇒ Acceleration = 19.44 / 1.64

⇒ Acceleration = 12.62 m/s²

Thus, The greyhound's average acceleration will be;

⇒ Acceleration = 12.62 m/s²

Answer 2
Answer:  Use the acceleration formulae:\[Final velocity (v) - Initial velocity (u) / time taken\]
so it is A

2A bag contains only red and blue marbles. Yasmine takes one marble at random from the bag. The probability that she takes a red marble is 1 in 5. Yasmine returns the marble to the bag and adds five more red marbles to the bag. The probability that she takes one red marble at random is now 1 in 3. How many red marbles were originally in the bag?
10 red
3 red
5 red
2 red

Answers

Originally, there were
x = 5 red
4x = 20 blue

Now, there are
x+5 = 10 red
4x = 20 blue


What fractions are equivalent to 4/7

Answers

Some of the fractions that are equivalent to 4/7 are 8/14, 12/21, 16/28, 20/35 e.t.c

What is equivalent expression?

Equivalentexpressions are expressions that work the same even though they look different.

If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.

For example , 5 × 4 = 20 and 2 × 10 = 20 , so the two expressions are equivalent and they have thesame value

To find the equivalent of 4/7, we can multiply through by a factor of 2, 3 , 4 ,5 e.t.c

Therefore 4/7 = 8/14 = 12/21 = 16/28 = 20/35
