To find Ilana's average speed, we divide the total laps by the total minutes, which results in one-fourth of a lap per minute.
Explanation:To find the average speed, we divide the total distance by the total time taken
To determine Ilana's average speed, we need to divide the total distance (2 laps) by the total time (8 minutes). When we do that, we get 0.25 laps per minute.
This is also known as one-fourth of a lap per minute. That means, on average, Ilana completes a quarter of a lap every minute.

One more than three-eighths of a number is eleven. Just write out equation do not solve please
Answer:
Let's just call the number x. 3/8ths of x and 1 more equals 11.
As an equation, this basically means
[tex]\frac{3}{8} x+1=11[/tex]
The equation derived from the given statement "One more than three-eighths of a number is eleven" is 3/8 * X + 1 = 11.
Explanation:In mathematics, especially in algebra, we often have to deal with problems where a certain relationship is given between a number and its fraction, and the task is to find the number. In the problem you presented, "One more than three-eighths of a number is eleven", we are required to express this problem as an equation.
The three-eighths of a number can be represented as 3/8 * X (where X is the unknown number we're seeking), and 'one more than' simply means we're adding 1 to this fraction. The given relationship states that this result is eleven.
So, the equation can be written as: 3/8 * X + 1 = 11.

In a Calculus class, there are 11 freshman and 15 sophomores; 5 of the sophomores are females,
and 8 of the freshman are males. If a student is selected at random, what is the probability of
selecting a freshman or a female? P(Freshman or Female)=
Using it's concept, it is found that there is a 0.6154 = 61.54% probability of selecting a freshman or a female.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, there is a total of 26 students. Of those, the desired outcomes are composed by the 11 freshmen students plus the 5 sophomore females, hence:
p = 16/26 = 0.6154.
0.6154 = 61.54% probability of selecting a freshman or a female.
More can be learned about probabilities at https://brainly.com/question/14398287
Final answer:
To find the probability of selecting a freshman or a female from the calculus class, we calculate the combined unique count of freshmen and females and divide by the total number of students, resulting in a probability of approximately 69.23%.
Explanation:
The question asks for the probability of selecting a freshman or a female student from a calculus class with a total of 11 freshmen and 15 sophomores, where 5 of the sophomores are females and 8 of the freshmen are males. First, let's identify the totals: there are 26 students in total (11 freshmen + 15 sophomores). To find the number of freshmen or females, we consider that there are 3 freshmen females (11 freshmen - 8 males) and 10 sophomore females in total (5 sophomores who are female plus 5 presumed male due to the lack of additional gender data).
So, the number of unique freshmen or female counts is: the 11 freshmen (regardless of gender) plus the 10 females not counted among freshmen (5 sophomores who are females plus an assumed 5 other females given the data isn't explicit about these being the same or different students), minus the 3 freshmen females who are already counted in the freshman group. This gives a total of 18 unique freshmen or females. Therefore, the probability of selecting a freshman or a female is [tex]\(\frac{18}{26}\)[/tex], which simplifies to [tex]\(\frac{9}{13}\)[/tex] or approximately 69.23%.

the discriminant of x2 + 6x + 9 = 0
Answer:
D = 0
Step-by-step explanation:
D = b^2 - 4ac =
= 6^2 - (4*1*9) =
= 36 - 36 = 0
Final answer:
The discriminant of the quadratic equation x² + 6x + 9 = 0 is 0, which means there is one real root, and the graph of the equation is tangent to the x-axis at one point.
Explanation:
The discriminant of a quadratic equation is the part of the formula b² - 4ac that determines the nature of the roots of the equation. For the quadratic equation x² + 6x + 9 = 0, we can identify a = 1, b = 6, and c = 9. Using the discriminant formula, we get:
• Discriminant, D = b² - 4ac
• D = (6)² - 4(1)(9)
• D = 36 - 36
• D = 0
Since the discriminant is zero, it indicates that the quadratic equation has one real root, and the graph of the equation touches the x-axis at one point (the vertex of the parabola).
Steve will roll a number cube, numbered 1-6, twice. What is the probability
of rolling a number > 3, then rolling a prime number? Simplify your answer!
Answer:
25%
Step-by-step explanation:
First we calculate the probability of rolling a number greater than 3, that is, it can be 4, 5 or 6.
The probability of each number is 1/6, so:
P1 = (1/6) + (1/6) + (1/6) = 3/6 = 1/2
Then, we calculate the probability of rolling a prime number, that is, 2, 3 or 5.
As we have again 3 numbers, the probability P2 will also be 1/2
Then, the final probability is the product of both P1 and P2:
P = P1 * P2 = (1/2) * (1/2) = 1/4 = 25%

Step-by-step explanation:
Volume for finding any shape is V= Bh where b is the area of he base multiplied by the height of the shape. Find the area of the circle, which is pi times the radius squared 9 times 9 is 81. Multiply 81 by pi or 3.14159265 is 254. 4690047. Then, multiply that number 6 which is the height of your shape, and you get 1526.814028. Rounded to the nearest tenth is 1526. 8 cubic feet. Hope this helps!
The Volume of Cylinder is 1,526.04 ft².
What is Volume?Volume is a three-dimensional measurement that's used to gauge a solid shape's capacity. It implies that the volume of a closed form determines how much space it can occupy in three dimensions.
As, the Volume of Cylinder = πr²h where r is the radius and h is the height.
Given:
Radius of cylinder = 9 feet
Height of cylinder = 6 feet
So, Volume of Cylinder
= πr²h
= 3.14 x 9 x 9 x 6
= 3.14 x 81 x 6
= 1,526.04 ft²
Thus, the volume is 1,526.04 ft².

Max Steel drives his 1969 Mustang 15 miles per hour. If there are 5280 feet in one mile and 60 seconds in one minute, how many feet can he go per second?
Answer:
22 feet per second
Step-by-step explanation
15x5280=79,200
79,200/60=1320 feet per minute since 60 minutes per hour
1320/60=22 feet per second since 60 seconds per minute
Max Steel's Mustang can go upto 22 feet per second.
First, convert miles per hour to feet per hour. Since there are 5280 feet in a mile, multiply the speed in miles by the number of feet in a mile:
Step 1: 15 miles/hour x 5280 feet/mile = 79200 feet/hour
Step 2:Next, convert feet per hour to feet per minute. Since there are 60 minutes in an hour, divide by 60:
79200 feet/hour ÷ 60 = 1320 feet/minute
Step 3: Finally, convert feet per minute to feet per second. Since there are 60 seconds in a minute, divide by 60:
1320 feet/minute ÷ 60 = 22 feet/second
Therefore, Max Steel can go 22 feet per second.

You are measuring the height of a lamppost. You stand 40 inches from the base
of the lamppost. You measure the angle of elevation from the ground to the top!
of the lamppost to be 70°. Find the height h of the lamppost to the nearest inch.
Answer:
110in
Step-by-step explanation:
The horizontal distance from where you stand to the lamp post is 40 inches.
Let the height of the lamp post be y inches.
The angle of elevation from the ground to the top!
of the lamppost to be 70°.
The height , y and the horizontal distance, form the legs of a right triangle .
We can use the tangent ratio, to calculate the height of the lamp post .
[tex] \tan(70 \degree) = \frac{y}{40} [/tex]
[tex]y = 40 \tan(70) [/tex]
[tex]y = 109.9[/tex]
To the nearest inch, the height is 110 inches
The height of the lamppost is approximately 110 inches, calculated using the tangent of a 70° angle with a base distance of 40 inches.
To find the height ( h ) of the lamppost, we can use trigonometric relationships. Given that we stand 40 inches from the base of the lamppost and measure the angle of elevation to be 70°, we can use the tangent function:
[tex]\[\tan(\theta) = \frac{\text{opposite}}{\text{adjacent}}\][/tex]
In this scenario:
- The angle [tex]\(\theta = 70^\circ\)[/tex]
- The adjacent side (distance from the base) is 40 inches
- The opposite side is the height \( h \) of the lamppost
Using the tangent function, we have:
[tex]\[\tan(70^\circ) = \frac{h}{40}\][/tex]
To solve for ( h ), we rearrange the equation:
[tex]\[h = 40 \cdot \tan(70^\circ)\][/tex]
Now we need to calculate [tex]\( \tan(70^\circ) \):[/tex]
[tex]\[\tan(70^\circ) \approx 2.747\][/tex]
Multiplying this by 40 inches:
[tex]\[h = 40 \cdot 2.747 \approx 109.88\][/tex]
Rounding to the nearest inch:
[tex]\[h \approx 110 \text{ inches}\][/tex]
Therefore, the height of the lamppost is approximately 110 inches.
