Answer: 462
Step-by-step explanation:
Answer:
540 mins | 9 hours | 540, 9
420 mins | 7 hours | 420, 7
300 mins | 5 hours | 300, 5
180 mins | 3 hours | 180, 3
Step-by-step explanation:
1 hour = 60 mins
To convert hours into minutes, multiply the number of hours by 60 minutes:
9 hours × 60 mins = 540 mins
7 hours × 60 mins = 420 mins
5 hours × 60 mins = 300 mins
3 hours × 60 mins = 180 mins
The ratio of a : b is 1 : 2
Step-by-step explanation:
A ratio is a relationship between two numbers indicating how many times the first number contains the second number
Ex: If there are eight oranges and six bananas, then the ratio of oranges to bananas is eight to six, and is written as 8 : 6, which is equivalent to the ratio 4 :3 in its simplest form
∵ a + b = 3a
- To find the ratio between a and b find b in terms of a
- Subtract a from both sides
∴ b = 2a
→ a : b
Substitute b by 2a
→ a : 2a
Divide both terms by a
→ 1 : 2
∴ a : b = 1 : 2
The ratio of a : b is 1 : 2

<h3>
Answer:</h3>
10.
<h3>
Step-by-step explanation:</h3>
In order to find the missing value, we need to divide 173.1, by 17.31:
173.1 / 17.31 = 10
Dividing the product (173.1) by one value in the equation (17.31) can represent what the missing value is, in order for 17.31 to equal 173.1
<h3>
Check:</h3><h3>
</h3>
17.31 · 10 = 173.1
173.1 / 10 = 17.31
Answer:
About 2.569 seconds
Step-by-step explanation:
To solve this problem, you can separate it into two half parabolas. The beginning part is initial upward rising. To calculate the amount of time that this part of the dive takes, you can use the formula 
, where 
is the final velocity, 
is the initial velocity, a is the acceleration due to gravity, and t is the amount of time it takes. You know that the final velocity is 0, since the diver is reaching the terminal of their dive. Therefore, you can set up the following equation (assuming that the acceleration due to gravity is 32ft/s^2):
seconds
To find the height that this indicates the diver has risen, you can plug this time into the following formula: 
feet
For the second part, you can use the equation again. Since the initial velocity for this part is 0, you can set up the following equation:
Adding this to the time that the first part of the dive takes, you get a total of about 2.569 seconds. Hope this helps!
