The skateboarder's rate of ollies per minute would be 68 ollies per minute. The skateboarder's rate of ollies per hour would be 4080 ollies per hour.
Explanation:To find the rate of ollies per minute, we need to divide the number of ollies completed in 30 seconds by the number of seconds in a minute. In this case, the skateboarder completed 34 ollies in 30 seconds, so the rate of ollies per minute would be:
Rate per minute = (34 ollies / 30 seconds) × (60 seconds / 1 minute) = 68 ollies per minute
To find the rate of ollies per hour, we need to divide the number of ollies completed in 30 seconds by the number of seconds in an hour. In this case, the skateboarder completed 34 ollies in 30 seconds, so the rate of ollies per hour would be:
Rate per hour = (34 ollies / 30 seconds) × (3600 seconds / 1 hour) = 4080 ollies per hour

The function f(t) = 5*cos ((pi/4)*t) + 11 represents the tide in Dark Sea. It has a maximum of 16 feet when time (t) is 0 and a minimum of 6 feet. The sea repeats this cycle every 8 hours. After six hours, how high is the tide?
A. 11 feet
B. 6 feet
C. 8.5 feet
D. 10.5 feet
After six hours, the tide is 11 feet high.
What is function?"It defines a relation between input and output values.""In function, for each input there is exactly one output."For given question,
We have been given a function [tex]f(t)=5\times cos((\frac{\pi}{4} )t)+11[/tex]
which represents the tide in Dark Sea and t represents the time in hours.
We need to find the height of the tide after 6 hours.
For t = 6, we need to find the value of function f(t)
[tex]\Rightarrow f(6)=5\times cos((\frac{\pi}{4} )6)+11\\\\\Rightarrow f(6)=5\times cos((\frac{3\pi}{2} ))+11\\\\\Rightarrow f(6)=0+11\\\\\Rightarrow f(6)=11[/tex]
Therefore, after six hours, the tide is 11 feet high.

A dripping faucet wastes a cup of water if it drips for three minutes. The amount of water wasted varies directly with the amount of time the faucet drips. What is the constant of variation?
A. 1/3
B. 2
C. 1/2
D. 3
Answer:
A. 1/3
Step-by-step explanation:
Suppose x represents the amount of the water ( in cups ) wasted in t minutes,
∵ The amount of water wasted varies directly with the amount of time the faucet drips,
⇒ x ∝ t
⇒ x = kt
Where,
k = constant of variation,
If x = 1, t = 3,
[tex]\implies 1 = k(3)\implies k = \frac{1}{3}[/tex]
Hence, the constant of variation is [tex]\frac{1}{3}[/tex]

3.31227766,rational
18.16227766,irrational
18.16227766,rational
Answer:
3.46227766; irrational
Step-by-step explanation:
The sum of 3/10 and √10 can be written mathematically as:
3/10 + √10
Taking the LCM which is 10
3/10 + √10 = 0.3 + 3.16227766
= 3.46227766
Since we cannot express the resulting value as a ratio of two integers, therefore the value is classified as an irrational number.

What is the product of −3 1/4 and −1 1/2 ? Enter your answer as a mixed number, in simplified form, in the box.
Answer:
Mixed number is [tex]4\frac{7}{8}[/tex] and the simplified form of this mixed number is [tex]\frac{39}{8}[/tex].
Step-by-step explanation:
The two mixed numbers are
[tex]-3\frac{1}{4}=-\frac{13}{4}[/tex]
and [tex]-1\frac{1}{2}[/tex]
= [tex]-\frac{3}{2}[/tex]
Now we will multiply these negative fractions.
[tex](-\frac{13}{4})(-\frac{3}{2})[/tex]
When two negative signs get multiplied they become positive.
= [tex]\frac{13}{4}\times \frac{3}{2}[/tex]
= [tex]\frac{39}{8}[/tex]
= [tex]4\frac{7}{8}[/tex]
Therefore, mixed number is [tex]4\frac{7}{8}[/tex] and the simplified form of this mixed number is [tex]\frac{39}{8}[/tex].

Edwin walks for 2 1/2 hours. He walks 1 2/3 miles in the first hour, 1 3/4 miles in the second hour and 1/4 of the total distance in the last 1/2 hour.What is the total distance Edwin walks?
Answer:
The total distance is 41/9 = 4 5/9 miles
Step-by-step explanation:
Total time is 2 1/2 hours.
First hour, he walks 1 2/3 = 5/3 miles.
Second hour, he walks 1 3/4 = 7/4 miles.
The last half hour he walks 1/4 of total distance. If we call total distance x.
[tex]\frac{5}{3} + \frac{7}{4} +\frac{x}{4} = x[/tex]
Now, we can eliminate the denominator, multiplying by four and by three.
[tex]5*4 + 7*3 + 3*x = 4*3*x\\20 + 21 + 3x = 12 x\\41 +3x = 12x \\41 = 12x - 3x\\41 = 9x\\x = 41/9\\x = 4 \frac{5}{9}[/tex]
Total distance is 4 5/9 miles

John made $195 for 13 hours of work. At the same rate, how much would he make for 17 hours of work?
Final answer:
John's hourly wage is calculated to be $15 per hour. For 17 hours of work at this rate, John would earn $255.
Explanation:
John made $195 for 13 hours of work, which means his hourly wage is the total amount earned divided by the total hours worked. To find John's hourly wage we calculate $195 ÷ 13 hours = $15 per hour. To determine how much he would make for 17 hours of work at this same rate, we multiply his hourly wage by 17 hours.
$15 per hour × 17 hours = $255
Therefore, at the same hourly rate, John would make $255 for 17 hours of work.
Write and solve an equation to answer the question How many people must attend the third show so that the average attendance per show is 30007 Theater Attendance, first show is 2580,second show is 2920.
To achieve an average attendance of 30007 over three shows with the first two shows having audiences of 2580 and 2920 respectively, 84421 people must attend the third show.
Explanation:The subject here is Mathematics and we will be solving for the average attendance required for three shows to have an average of 30007 attendees per show.
Let's denote the number of people that need to attend the third show by 'x'. According to the problem, the average attendance of the three shows should be 30007, hence:
(2580 + 2920 + x) / 3 = 30007
This simplifies to 5500 + x = 90021
Subtracting 5500 from both sides, we get:
x = 90021 - 5500
Therefore, a total of 84421 people need to attend the third show for the average attendance across all three shows to be 30007.

There are three liters Of apple juice at a school party. 10 students want to drink all of the apple juice, and they all want to get exactly the same amount. How much apple juice can each student have?
To calculate the amount of apple juice each of the 10 students can have, divide the total volume of 3 liters by 10, resulting in 0.3 liters per student.
The question involves dividing a total volume of liquid evenly among a number of participants, which is a basic arithmetic problem in mathematics, specifically dealing with division.
To find out how much apple juice each student can have, you need to divide the total amount of apple juice by the number of students. There are 3 liters of apple juice and 10 students. So, each student can have 3 liters / 10 students = 0.3 liters of apple juice. A liter is a unit of capacity, and it's comparable to a jug of milk or a bottle of soda, which also holds a similar amount of liquid. Hence, the volume in this context is measured in liters. When you divide the total volume of apple juice by the number of students, you get the volume that each student will receive.
