Answer
49.67mph
Step-by-step explanation:
Data: 53 miles
1 hour 4 minutes.
Convert 4 minutes to hours:
4/60 = .067
Add like terms (hours)
1+ 0.067= 1.067
mph = m/h
mph = 53/1.067 = 49.67mph
The average speed of the car will be 49.67mph.
The speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. The speed is a scalar quantity and does not require any direction to represent it.
Given that Chloe drives from her house to her grandma's house 53 miles away in an hour and 4 minutes. The speed will be calculated by using the formula below:-
Distance traveled = 53 miles
Time = 1 hour 4 minutes.
Convert 4 minutes to hours:
4/60 = .067
Add like terms (hours)
1+ 0.067= 1.067
Now the speed will be:-
Speed = Distance / Time
Speed = 53 / 1.067
Speed = 49.67 mph
Therefore, the average speed of the car will be 49.67mph.

A dime is 1/10 fraction of a dollar.
Fractions are numbers which are of the form a/b where a and b are real numbers. This implies that a parts of a number b.
Here, a is called the numerator and b is called the denominator. Any number can be expressed as fractions.
We have to convert a dime into a fraction of a dollar.
Number of dimes in a dollar = 10
10 dimes = 1 dollar
1 dime = 1/10 dollar
So we can say that one dime is 1/10 of a dollar.
Hence 1/10 fraction of a dollar is 1 dime.

Answer:
1/10
Step-by-step explanation:
The question relates to sequential probability. A black marble must be picked first to add blue marbles to the pot. The combined probability of these events is 169/1040.
The subject is probability within mathematics. In order to determine the probability of picking a blue marble as the second marble, it is important to understand that this can only happen if a black marble was chosen first (because blue marbles are only added after a black marble is chosen). Initially, we have 14 red marbles and 26 black marbles. Therefore, the probability of picking a black marble first is 26/40.
After the first black marble is chosen, 13 blue marbles are added, making the total number of marbles 53. As a result, the probability of picking a blue marble as the second draw is 13/53.
Since these are sequential events, we multiply the probabilities together. Therefore, the probability of the second marble being blue is (26/40) * (13/53), which simplifies to 169/1040 or approximately 0.1625.
