Michel started to drive from New York to Washington, DC, which is 120 miles away, at 7:00 AM. For the first hour and a half of her trip, Michel was driving at a speed of 50 mph. What was her average speed during the second part of the trip, if she reached Washington at 10:00 AM?
Answer:
The average speed on the second part was 30 mph.
Step-by-step explanation:
The whole trip between New York and Washington is 120 miles. On the first part he drove at 50 mph for 1.5 h, from 7 AM to 8:30 AM, therefore he drove a distance of:
distance = speed*time = 50*1.5 = 75 miles
So the second part had a length of 120 - 75 = 45 miles. With an elapsed time of 1.5h, therefore the average speed was:
speed = distance / time
speed = 45 / 1.5
speed = 30 mph
The average speed on the second part was 30 mph.

Denote the equation : y = ax + b
Use the first 2 values of x and y in table:
3a + b = 21
5a + b = 35
Subtract the 2 equations:
=> 2a = 14 => a = 7 => b = 21 - 3 x 7 = 0
=> The solution is y = 7x
9.
Denote the equation : y = ax + b
Use the first 2 values of x and y in table:
5a + b = 17
10a + b = 22
Subtract the 2 equations:
=> 5a = 5 => a = 1 => b = 17 - 5 x 1 = 17 - 5 = 12
=> The solution is y = x + 12

5(42 - 12) = 5(30)
Answer:
B
Step-by-step explanation:
Given
5(42) - 5(12) ← factor out 5 from each term
= 5(42 - 12)
= 5(30)

It costs $20.50 to enter an amusement park and $0.25 to ride a ride. You have $21.50. Write an equation that represents the number r of rides you can ride.
An equation is
________ =21.50.
Answer: 0.25r + 20.50= 21.50; You'd only be able to go on four rides.
Let r represent how many rides you can go on
21.50-20.50 ( Money you have now - cost to enter), this leaves you with $1 left.
0.25r = $1
0.25(4)= $1
Therefore r =4. And you would only be able to go on four rides.
Answer:
4
Step-by-step explanation:
[tex] 0.25\:r + 20.50 = 21.50\\
0.25\:r = 21.50 - 20.50\\
0.25\:r = 1\\
r = \frac{1}{0.25}\\
r = \frac{100}{25}\\
r = 4\\[/tex]

The answer is Option D, 25/576.
Probability is the ratio of the number of outcomes in an exhaustive set of equally likely outcomes that produce a given event to the total number of possible outcomes.
How to find the probability that the chosen marbles are both blue?
Given that Amber has a bag of 24 marbles. 7 marbles are red, 5 marbles are blue, and the rest are pink. James takes out two marbles without replacing them.
The probability of getting a blue marble is 5/24.
(The ratio of the number of blue marbles to the total number of marbles)
The probability of getting two blue marbles is
=> 5/24×5/24 = 25/576.

The number of bags of candy that Shelly ordered is 16.
What is Division?Division is one of the operation in mathematics where number is divided into equal parts as that of a definite number.
Given hat,
Total amount that Shelly paid = $15
Shipping flat rate = $3
Total amount for the bags = 15 - 3 = $12
Cost of each bag = $0.75
Number of bags bought = 12 / 0.75 = 16
Hence the total number of bags is 16.

Log base 32 of 2
Help
Answer:
[tex]log_{32}(2)=0.2[/tex]
Step-by-step explanation:
Recall that the unknown (x) here is the log base 32 of 2, so we can write this as the equation:
[tex]log_{32}(2)=x[/tex]
The above equation can be solved by the "change of base formula":
[tex]x=\frac{log(2)}{log(32)} \\x=0.2[/tex]
We can also answer this by trying to solve the exponential equation:
[tex]32^x=2[/tex]
Where we are asked what is the exponent (x) at which we need to raise the base (32) in order to obtain the answer "2"?
Notice that since
[tex]2^5=32[/tex]
Then [tex]32^{1/5} = 2[/tex]
And 1/5 = 0.2 which also agrees with our previous answer

Apply the formula of each shape to determine the
volumes
What is the exact volume of the composite figure?
V=
л cm3
V (cone) = (1÷3) × (r×r×h) л cm3
3 cone = 1 cylinder (if "h" and "r" is same)
There is two cone...
1st one: (1÷3) × 3×3×5 л cm3 = 15л cm3
2nd one: (1÷3) × 3×3×8 л cm3 = 24л cm3
15 + 24 = 39л cm3
The exact volume of the composite figure is,
⇒ 122.46 cm³
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;
Radius of cone = 3 cm
Upper height of cone = 5 cm
Lower height of cone = 8 cm
Now, We get;
Volume of cone = πr²h / 3
Hence, For upper cone is,
⇒ V = 3.14 × 3² × 5 / 3
⇒ V = 47.1 cm³
For lower cone is,
⇒ V = 3.14 × 3² × 8 / 3
⇒ V = 75.36 cm³
Thus, The exact volume of the composite figure is,
⇒ 47.1 + 75.36
⇒ 122.46 cm³
