So, she has a total of 4 books in her book shelf.
So, the number of positions in which the books have to be put are four.
As we can see,
The books are only one in number each. So, the choices are not repeatable.
So,
In first position we have four choices, in third we will be left with three choices, in the seconds position we will have a total of two books as choice and in the last positive we have to put the book that is left.

carlos swam to the bottom of a pool that is 12 feet deep. what is the opposite of carlos's elevation relative to the surface ?
A -12 C 12 feet
B 0 feet D 1/12 foot
The opposite of Carlo's elevation is 12 feet
Carlos is said to have submerged himself in a 12-foot-deep swimming pool.
Carlos' elevation will be -12 feet with regard to the surface because he submerged himself to the pool's bottom.
The elevation of Carlos as it relates to the ground would be opposite of -12 feet, or -(- 12) feet.
12 feet
Carlos' elevation in relation to the ground is therefore 12 feet higher than it should be.
Thus the opposite of Carlo's elevation is 12 feet .

If they all ran the same number of laps, what is the distance each player ran? At the end of practice, each player ran to the store, which was 10.31 meters from the field. What is the total distance each of them ran?
The distance each player ran for warm up laps is 875 cm and the distance each player ran for the store is 1.47 meters.
According to the question,
We have the following information:
Adrianna’s football team ran some warm up laps with a total distance of 6125 centimeters. There are 7 players on her football team.
The distance to the store = 10.31 meters
Now, we can find the distance ran by each player by dividing the total distance by number of players.
Distance for warm up laps = 6125/7
Distance ran by each player = 875 cm
Distance for the store = 10.31/7
Distance for the store = 1.47 m
Hence, the distance each player ran for warm up laps is 875 cm and the distance each player ran for the store is 1.47 meters.

Equation of line having passing points (-6,0) and (0,-24) is 4x + y + 24 = 0
What do you mean by equation of line?
The general equation for every straight line is y = mx + c, where m is the gradient (or degree of steepness) of the line and c is the y-intercept (the point in which the line crosses the y-axis).
The variables x and y are related to coordinates on the line in the linear equation y = mx + c.
The formula y = mx + c yields a result for y when we enter a value for x.
As y depends on the value of x, it follows that x is an independent variable and y is a dependent variable.
Two passing points of line are (-6,0) and (0,-24)
Equation of line having two passing points as (a,b) and (c,d) is
[tex](y-b) = \frac{d-b}{c-a} (x-a)[/tex]
So, here equation of line become ,
[tex](y - 0) = \frac{-24-0}{0+6}(x+6)[/tex]
⇒ [tex]y = \frac{-24}{6}(x+6)[/tex]
⇒ y = -4(x+6)
⇒ y = -4x - 24
⇒ 4x + y + 24 =0
Hence, equation of line having passing points (-6,0) and (0,-24) is 4x + y + 24 = 0

The speed in miles per hour for the given situation is 3.75 miles per hour.
Given that, walks 3/4 mile in 1/5 hour.
What is the speed?The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.
We know that, Speed = Distance/Time
= 3/4 ÷ 1/5
= 3/4 × 5/1
= 15/4
= 3.75 miles per hour
Hence, the speed in miles per hour for the given situation is 3.75 miles per hour.

There is a sector of a circle:
The radius is 5.2
The arc length is 6π
You are not given the angle of the sector
Find the area of the sector, and give your answer in terms of pi I got 49π, let me know if I'm right ty. I've attached my working out
Answer:
Area of sector is 15.6π========================
Let the central angle be α.
Arc length equations = 2πr × α/360, if α in degreess = 2πr × α/2π = αr, if α in radiansWe have s = 6π and r = 5.2Find the central angles = αr6π = 5.2αα = 6π/5.2Area of sectorA = r²α/2, when α in radiansSubstitute the value of αA = 5.2² × 6π/5.2 × 1/2 = 5.2 × 3π = 15.6πNote: You could get it more easily if considered 360° = 2π in your calculations.
Answer:
[tex]\dfrac{78}{5} \pi = 15.6 \pi[/tex]
Step-by-step explanation:
Given values:
Radius (r) = 5.2Arc length = 6πAs the arc length is given in terms of pi, use the formulas where the angle is measured in radians.
[tex]\boxed{\begin{minipage}{6.3 cm}\underline{Arc length}\\\\Arc length $=r \theta$\\\\where:\\ \phantom{ww}$\bullet$ $r$ is the radius. \\ \phantom{ww}$\bullet$ $\theta$ is the angle measured in radians.\\\end{minipage}}[/tex]
Substitute the given values into the arc length formula to calculate the central angle (in radians):
[tex]\implies 6\pi=5.2\; \theta[/tex]
[tex]\implies \theta=\dfrac{6\pi}{5.2}[/tex]
[tex]\implies \theta=\dfrac{15}{13}\pi[/tex]
[tex]\boxed{\begin{minipage}{6.3 cm}\underline{Area of a sector of a circle}\\\\Area of a sector = $\dfrac12 r^2 \theta$\\\\where:\\ \phantom{ww}$\bullet$ $r$ is the radius. \\ \phantom{ww}$\bullet$ $\theta$ is the angle measured in radians.\\\end{minipage}}[/tex]
Substitute the radius and the found angle into the formula and solve for area:
[tex]\begin{aligned}\implies \textsf{Area of the sector}&=\dfrac{1}{2}(5.2)^2 \left(\dfrac{15}{13}\pi\right)\\\\&=\dfrac{1}{2}(27.04) \left(\dfrac{15}{13}\pi\right)\\\\&=(13.52) \left(\dfrac{15}{13}\pi\right)\\\\&=\dfrac{78}{5}\pi \\\\&=15.6 \pi\end{aligned}[/tex]
